==Overview of DIY Hardware Approaches That Work With Vixen==

This section provides information about Do-It-Yourself (DIY) hardware that works with the [[Vixen]] software program. Vixen is a Windows (.NET Framework 2) program that runs on a PC, and is used to create and run light shows that may be synchronized to music. Here is a brief list of the DIY approaches that you can take that will work with Vixen.

===Non-Dimmable Light Controllers===

====SSR Direct Attach====

* Controlled through: Parallel Port
* Documentation: [[Solid State Relays]]

If you need 12 or fewer channels, you can just buy or build SSRs and connect them to the parallel port on your PC, and use them to turn 110VAC light strings (or just plain lamps) on and off (no dimming). These ssrs must be sourced or positive switched. From time to time there are coop buys of SSR boards,but these are usually sinked, and/or parts, to reduce your expense. You could place a couple ULN2803s and use the coop sinked ssrs. For more information on this come over to the forum and/or ask on the LiveChat.

====Kit74====
*Controlled through: Parallel Port

This is a kit with mechanical relays that can be purchased from various places. It is similar to the SSR Direct Attach, although the mechanical relays are noisy and have a limited lifespan. There are probably other similar kits available as well.

====Hill320====
* Controlled through: Parallel Port
* Documentation: http://computerchristmas.com/christmas/link-how_to/HowToId-4/How_To_Build_A_Parallel_Port_Controller_Box

This is a controller originally designed by Hill Robertson http://computerchristmas.com to allow up to 320 channels to be controlled by a PC, and requires an external power supply and SSRs. There isn't any coop board for this design at the moment. It is a more complicated design, and it is not currently recommended for newbies.

====Olsen 595/Grinch====
*Controlled through: Parallel Port
*Documentation: [[The GRINCH Controller]], [[GRINCH Controller Assembly Instructions]]
*Documentation: [[Olsen 595]]

This is a popular controller based on an approach first popularized on the http://computerchristmas.com and/or http://planetchristmas.com forums by Peter Olsen. In its first incarnation it used 8-bit 74HC595 logic chips, often with external buffers, while a later design (Grinch), popularized by Robert Jordan, uses 16-bit chips specialized for this use. There are coop boards available for both of these designs. These coop boards need external power supplies, and work with external (coop) SSR boards to control AC lighting.

There are some variations of this approach that support dimming, but they are not as popular and there aren't any coop boards available. However, using a [[Ren-C]] board can add dimming capability to a 595 or Grinch, which causes the board to operate as a Renard board. There is also an option available to run a Grinch or 595 controller from DMX with full dimming capability [[DMX_to_Grinch/595_convertor | HERE]].

The Grinch board is a good choice if you need more than 12 channels but want a board that is simple to build. It doesn't use very many parts, and is easy to assemble.

===Dimmable Light Controllers===
====Firegod====
*Controlled through : Serial Port
*Documentation: [[Firegod]]

This is a modular system that supports 32 to 128 channels per serial port, in increments of 32 channels, with 100 levels of dimming (using pulse width modulation - PWM). It consists of a host controller module and one to four field modules. The SSRs are not included on these boards, and must be provided separately. The interface to this system is RS-232. This system is available on a coop basis from time to time, with the kits including the boards, the parts, and pre-programmed microcontroller chips (PICs). This board is intermediate in complexity to build.

====Renard====
*Controlled through: Serial Port
*Documentation: [[Renard]]

This is another modular system that supports a varying number of channels, depending on baud rate selection. It supports 256 levels of dimming, and can be configured with or without PWM, or for use in DC applications. There are several coop boards available for this system with varying capabilities. It can be a fairly complex system because there are so many options. More information is available at the link listed above.

====Lynx====
*Controlled through: [[DMX]]
*Manual [[LYNX_Controller_Manual]]
The Lynx is a DIY dimmer design that uses [[DMX]] as its protocol but uses standard Cat5 cable for interconnections. It's designed to be similar to the layout of commercially available dimmers (LOR, AL, etc). It is an all in one unit that has its own power supply and SSR's built into it. You connect your DMX Cat5 and plug it in. Lights plug into female cord connections that exit from the board. It allows for a full 256 levels of dimming. The starting address is programmed via vixen. Since it uses the DMX protocol you can run 512 channels of Lynx on one DMX universe at 25ms timming.

In an effort to prevent variations in the design (leading to complications for the newer builders), insure that troubleshooting help can be provided, and keep the total cost as low as possible it is done as a modified coop. All the parts including the PCB and an enclosure are included. The necessary PIC microprocessor will come with the program preloaded so that the builder will not need a PIC programmer. A detailed instruction manual with pictures is included and should allow anyone with basic soldering skills to successfully build the controller.

====Helix====
*Controlled through: Standalone
*Documentation: [[Helix]]

The Helix is a standalone, networkable, modular system that supports a virtually unlimited number of channels. It supports 256 levels of PWM dimming. A Helix system consists of a Helix Main board and up to three Helix Daughter boards. Each Main board and Daughter board can control up to 32 channels. The Main board and basic Daughter board uses the standard four channel SSR boards. There is a 32ch SSR Daughter board that has the SSRs integrated with a basic Daughter board. If more than 128 channels are needed another Helix system can be added to form a Helix Network. These systems stay sync’d via a wireless XBee link. Up to 251 additional Helix systems can be added to the Helix Network as long as they are within radio range of the first Helix system. This allows up to 32,128 channels in a pure Helix system.

Since it is a standalone system, the Helix is a fairly complex system to build and operate. In an effort to minimize the complexity, the design and firmware are configuration controlled by the original system designer, Gregory Bartlett (gmbartlett). The PCBs and preprogrammed EEPROMs are available from him. All PCBs are bare except for the Helix Main Board. Since it requires a surface mount microSD card socket, this part comes presoldered.

===Other Controllers (Signs, Servos, etc.)===
====LedTriks====
*Controlled through: Parallel Port
*Documentation: [[LedTriks Controller Assembly Instructions]] [http://www.christmasinshirley.com/wiki/images/8/8e/LEDTriks_Wiring_Schematic.pdf LedTriks Wiring Diagram]

This board controls low-voltage LED panel and was designed by Robert Jordan. These panels are typically 16 LEDs high by 48 LEDs wide, for a total of 768 LEDs. Vixen can control up to four panels through one parallel port, and can even display text.

One of the problems with the original LedTriks design was the load placed on the PC to chunk the data out the parallel port. The Triks-C and the PIX-C controllers were created to address these shortcomings.

=====Triks-C=====
*Controlled through: Serial port or USB/serial adapter.
*Documentation: [[TRIKSC]], [http://www.christmasinshirley.com/wiki/index.php?title=Image:TRIKSC_CONTROLLER_v.0.1_manual.pdf Manual in PDF format]

This is a an add-on controller/processor for the LedTriks. The TRIKS-C uses an ATMEL processor to take a LedTriks file and send it out to the LedTriks Controller, via the serial port.

=====PIX-C=====
*Controlled through: Serial port or USB/serial adapter.
*Documentation: [[PIX-C]]

This is an add-on controller/processor for the LedTriks. It is backward compatible with the TRIKS-C, and is based on the Microchip 16F688 processor.

====JEC Pixel Displays====
*Controlled through: [[DMX]]

Pixels are a stand-alone lighting fixture controlled by DMX-512. Each pixel has banks of red, green and blue wide-angle LEDs, currently six of each. Firmware is available in two versions: 3 and 4 channel. 3 channel requires a dmx channel for red, green and blue intensity. Four channel adds master intensity control to the original three.

Pixels require a stiff +12v switching power supply. Each circuit board draws ~ 130 mA at full brightness. Pixels chain together using standard CAT5 networking cable. Per the DMX spec, no more than 32 pixels should be connected together without using an optosplitter / signal buffer.

LED refresh rate is nearly 100 Hz.

More details can be found at http://www.response-box.com/rgblights

Currently in progress is a version of the firmware which will allow the DMX address to be changed in the field. Currently the address is hard-coded.

====rgbLED====
* Controlled through: Serial Port

The RGB LED's will have the ability to make hundreds of colors with a single led. They can be controlled individually, series, or parallel with each other. These are not able to be addressable individually as they have no control onboard. You will have to use DCSSR's, Franks Ren24LV, or a Grinch to turn each channel on and off to get the desired color. Each RGB LED will use 3 channels, 1 for each color. These would give you the ability to make strings out of these to have any color you want. It will also use less power compared to standard mini lights.

More information to follow as I start my testing.

====Color Stick====
* Controlled through: [[DMX]]
* Documentation: [[Color Stick]]

The color stick is an 8-channel RGB display that uses 16 RGB 5050-sized LEDs, two per channel. The color sticks can be connected end-to-end as they pass DMX.

====RS485 Splitter====
* Documentation: [[RS485 Splitter]]

The RS485 splitter is a 4-port non-isolated splitter, designed for driving the color stick, but useful for driving any RS485 devices, including DMX or Renard.

By Robert P Martin aka [http://www.doityourselfchristmas.com/forums/private.php?do=newpm&u=1269 RPM]

Like many others here, I too started out with a Grinch controller. It worked, but I soon realized that I wanted to have dimming, so this meant I had to spend more money and build another controller, or build my own dimming adapter and use my existing Grinch controller.

After looking at the options at the time, I decided to build my own dimming interface for my Grinch controller. I also wanted to use the DMX protocol, since I wanted to run my controller out in the yard some distance from my show computer in my garage, and by using DMX I could easily do this.

After a few months of trying different design prototypes, this is the design I came up with:

[[Image:Grinch_DMX_Dimmer_V2.jpg]]

[[Image:GrinchDMXdim_SCHEMATIC.JPG]]

I used this design in my display to run my Grinch controllers for my entire show the first year I ran a computerized show, and I continue to use it to run my 32 channel Megatree and it works very well, and best of all it dims! It also provides power for yor Grinch controller, so no other circuitry (other than a DMX dongle for your computer) is needed to run it.

Another plus about this design is it can also convert an Olsen 595 board to dimming as well!

This is brief a explanation of the operation:

JP1 is a termination jumper for the DMX signal. If this is the LAST device on the DMX line, put the jumper JP1 on it to terminate the 120 ohm resistor across the DMX buss. The DMX signal does not like to be unterminated, and if left unterminated it can do some strange things. If you have other DMX devices to hook up after this, plug them into this board and do not jumper JP1 the terminator on this board.

J1 on your Grinch controller should be jumpered so that the positive +5 side for operation will be provided through the RJ45 connector from the Grinch DMX dimmer adapter board.

This board uses what I call the "switchless" method of setting the DMX start channel, so you will also need to program the starting channel into the board before it will work.
It uses the sum of the first two DMX channels (channel 1 & 2) as the start channel address. This is done by powering the board off, then start vixen with the DMX plugin set for the all the channels.
Set the intensity levels to use the 255 level mode not the 100% mode. Create a sequence of 3 seconds or more and set the first channel to the intensity value of the channel you want the board to use as the first channel for the whole 3 seconds so this is the only value output for this channel. If you want the board to start on a channel higher than 255 than simply add the additional to the second channel.

For example, to start at channel 300, the first channel is set to 255 and the second is set to 45. Now make sure vixen is set to repeat the sequence and start it. Now with the power still off on the board put the JP3 jumper on and power up the board for 3 seconds. The board will light LED1 and LED 2 solid to indicate that the programming has been saved.
Now turn power to the board off and remove JP3 (operation mode). Your board DMX start channel is now programmed. Remember in my example (channel 300) I would use vixens channel 300 - 364 to control my board now. If it doesn't act like you think it should, reprogram it to channel 1 and try it. An easy way to "default" the board back to a start channel of 1 is to place JP3 on and remove the DMX input cable, power the board on until LEDs 1 & 2 light solid, power off, remove JP3 and when you power back up it will be set back to start channel 1.

You can reprogram it as much as you like as the life of the EEPROM is over 1 million cycles, so you should have a hard time breaking it. It will remember the information for about 40 years with the power off so you don't have to reprogram it unless you want to change the channel assigned.

A standard straight through CAT5 cable should be used between the converter and the Grinch/595 board. This converter will run 64 channels, so you will need one converter per Grinch controller.

The distance from the converter to the Grinch/595 controller should be kept as short as possible. I use a 1 foot cable with mine and mount it in the same enclosure as my Grinch controller, although I have tested it with up to a 15 foot cable.

Parts cost is about $25-30 and I occasionally run co-op's for this PC board and I try to keep a few extras on hand. If you would like more information, you can PM me at username [http://www.doityourselfchristmas.com/forums/private.php?do=newpm&u=1269 RPM]

==Overview of DIY Hardware Approaches That Work With Vixen==

This section provides information about Do-It-Yourself (DIY) hardware that works with the [[Vixen]] software program. Vixen is a Windows (.NET Framework 2) program that runs on a PC, and is used to create and run light shows that may be synchronized to music. Here is a brief list of the DIY approaches that you can take that will work with Vixen.

===Non-Dimmable Light Controllers===

====SSR Direct Attach====

* Controlled through: Parallel Port
* Documentation: [[Solid State Relays]]

If you need 12 or fewer channels, you can just buy or build SSRs and connect them to the parallel port on your PC, and use them to turn 110VAC light strings (or just plain lamps) on and off (no dimming). These ssrs must be sourced or positive switched. From time to time there are coop buys of SSR boards,but these are usually sinked, and/or parts, to reduce your expense. You could place a couple ULN2803s and use the coop sinked ssrs. For more information on this come over to the forum and/or ask on the LiveChat.

====Kit74====
*Controlled through: Parallel Port

This is a kit with mechanical relays that can be purchased from various places. It is similar to the SSR Direct Attach, although the mechanical relays are noisy and have a limited lifespan. There are probably other similar kits available as well.

====Hill320====
* Controlled through: Parallel Port
* Documentation: http://computerchristmas.com/christmas/link-how_to/HowToId-4/How_To_Build_A_Parallel_Port_Controller_Box

This is a controller originally designed by Hill Robertson http://computerchristmas.com to allow up to 320 channels to be controlled by a PC, and requires an external power supply and SSRs. There isn't any coop board for this design at the moment. It is a more complicated design, and it is not currently recommended for newbies.

====Olsen 595/Grinch====
*Controlled through: Parallel Port
*Documentation: [[The GRINCH Controller]], [[GRINCH Controller Assembly Instructions]]
*Documentation: [[Olsen 595]]

This is a popular controller based on an approach first popularized on the http://computerchristmas.com and/or http://planetchristmas.com forums by Peter Olsen. In its first incarnation it used 8-bit 74HC595 logic chips, often with external buffers, while a later design (Grinch), popularized by Robert Jordan, uses 16-bit chips specialized for this use. There are coop boards available for both of these designs. These coop boards need external power supplies, and work with external (coop) SSR boards to control AC lighting.

There are some variations of this approach that support dimming, but they are not as popular and there aren't any coop boards available. However, using a [[Ren-C]] board can add dimming capability to a 595 or Grinch, which causes the board to operate as a Renard board. There is also an option available to run a Grinch or 595 controller from DMX with full dimming capability [[DMX_to_Grinch/595_convertor | HERE]].

The Grinch board is a good choice if you need more than 12 channels but want a board that is simple to build. It doesn't use very many parts, and is easy to assemble.

===Dimmable Light Controllers===
====Firegod====
*Controlled through : Serial Port
*Documentation: [[Firegod]]

This is a modular system that supports 32 to 128 channels per serial port, in increments of 32 channels, with 100 levels of dimming (using pulse width modulation - PWM). It consists of a host controller module and one to four field modules. The SSRs are not included on these boards, and must be provided separately. The interface to this system is RS-232. This system is available on a coop basis from time to time, with the kits including the boards, the parts, and pre-programmed microcontroller chips (PICs). This board is intermediate in complexity to build.

====Renard====
*Controlled through: Serial Port
*Documentation: [[Renard]]

This is another modular system that supports a varying number of channels, depending on baud rate selection. It supports 256 levels of dimming, and can be configured with or without PWM, or for use in DC applications. There are several coop boards available for this system with varying capabilities. It can be a fairly complex system because there are so many options. More information is available at the link listed above.

====Lynx====

In an effort to prevent variations in the design (leading to complications for the newer builders), insure that troubleshooting help can be provided, and keep the total cost as low as possible it is done as a modified coop. All the parts including the PCB and an enclosure are included. The necessary PIC microprocessor will come with the program preloaded so that the builder will not need a PIC programmer. A detailed instruction manual with pictures is included and should allow anyone with basic soldering skills to successfully build the controller.

====Helix====
*Controlled through: Standalone
*Documentation: [[Helix]]

The Helix is a standalone, networkable, modular system that supports a virtually unlimited number of channels. It supports 256 levels of PWM dimming. A Helix system consists of a Helix Main board and up to three Helix Daughter boards. Each Main board and Daughter board can control up to 32 channels. The Main board and basic Daughter board uses the standard four channel SSR boards. There is a 32ch SSR Daughter board that has the SSRs integrated with a basic Daughter board. If more than 128 channels are needed another Helix system can be added to form a Helix Network. These systems stay sync’d via a wireless XBee link. Up to 251 additional Helix systems can be added to the Helix Network as long as they are within radio range of the first Helix system. This allows up to 32,128 channels in a pure Helix system.

Since it is a standalone system, the Helix is a fairly complex system to build and operate. In an effort to minimize the complexity, the design and firmware are configuration controlled by the original system designer, Gregory Bartlett (gmbartlett). The PCBs and preprogrammed EEPROMs are available from him. All PCBs are bare except for the Helix Main Board. Since it requires a surface mount microSD card socket, this part comes presoldered.

===Other Controllers (Signs, Servos, etc.)===
====Ledtriks====
*Controlled through: Parallel Port
*Documentation: [[LedTriks Controller Assembly Instructions]] [http://www.christmasinshirley.com/wiki/images/8/8e/LEDTriks_Wiring_Schematic.pdf LedTriks Wiring Diagram]

This is a controller to control low-voltage LED panels, designed by Robert Jordan. These panels are typically 16 LEDs high by 48 LEDs wide, for a total of 768 LEDs. Vixen can control up to four panels through one parallel port, and can even display text.

====Triks-C====
*Controlled through: Serial port or standalone
*Documentation: [[TRIKSC]], [http://www.christmasinshirley.com/wiki/index.php?title=Image:TRIKSC_CONTROLLER_v.0.1_manual.pdf Manual in PDF format]

This is a an add on controller/process for the Ledtricks. One of the problems with the original LEDTRIKS design was the load placed on the PC to chunk the data out the parallel port. The TRIKS-C uses a ATMEL process to take a LEDSTRIKS file and send it out to the LEDTRIKS Controller, via the serial prot.

====JEC Pixel Displays====
*Controlled through: [[DMX]]

Pixels are a stand-alone lighting fixture controlled by DMX-512. Each pixel has banks of red, green and blue wide-angle LEDs, currently six of each. Firmware is available in two versions: 3 and 4 channel. 3 channel requires a dmx channel for red, green and blue intensity. Four channel adds master intensity control to the original three.

==Overview of DIY Hardware Approaches That Work With Vixen==

This section provides information about Do-It-Yourself (DIY) hardware that works with the [[Vixen]] software program. Vixen is a Windows (.NET Framework 2) program that runs on a PC, and is used to create and run light shows that may be synchronized to music. Here is a brief list of the DIY approaches that you can take that will work with Vixen.

===Non-Dimmable Light Controllers===

====SSR Direct Attach====

* Controlled through: Parallel Port
* Documentation: [[Solid State Relays]]

If you need 12 or fewer channels, you can just buy or build SSRs and connect them to the parallel port on your PC, and use them to turn 110VAC light strings (or just plain lamps) on and off (no dimming). These ssrs must be sourced or positive switched. From time to time there are coop buys of SSR boards,but these are usually sinked, and/or parts, to reduce your expense. You could place a couple ULN2803s and use the coop sinked ssrs. For more information on this come over to the forum and/or ask on the LiveChat.

====Kit74====
*Controlled through: Parallel Port

This is a kit with mechanical relays that can be purchased from various places. It is similar to the SSR Direct Attach, although the mechanical relays are noisy and have a limited lifespan. There are probably other similar kits available as well.

====Hill320====
* Controlled through: Parallel Port
* Documentation: http://computerchristmas.com/christmas/link-how_to/HowToId-4/How_To_Build_A_Parallel_Port_Controller_Box

This is a controller originally designed by Hill Robertson http://computerchristmas.com to allow up to 320 channels to be controlled by a PC, and requires an external power supply and SSRs. There isn't any coop board for this design at the moment. It is a more complicated design, and it is not currently recommended for newbies.

====Olsen 595/Grinch====
*Controlled through: Parallel Port
*Documentation: [[The GRINCH Controller]], [[GRINCH Controller Assembly Instructions]]
*Documentation: [[Olsen 595]]

This is a popular controller based on an approach first popularized on the http://computerchristmas.com and/or http://planetchristmas.com forums by Peter Olsen. In its first incarnation it used 8-bit 74HC595 logic chips, often with external buffers, while a later design (Grinch), popularized by Robert Jordan, uses 16-bit chips specialized for this use. There are coop boards available for both of these designs. These coop boards need external power supplies, and work with external (coop) SSR boards to control AC lighting.

There are some variations of this approach that support dimming, but they are not as popular and there aren't any coop boards available. However, using a [[Ren-C]] board can add dimming capability to a 595 or Grinch, which causes the board to operate as a Renard board. There is also an option available to run a Grinch or 595 controller from DMX with dimming.

The Grinch board is a good choice if you need more than 12 channels but want a board that is simple to build. It doesn't use very many parts, and is easy to assemble.

===Dimmable Light Controllers===
====Firegod====
*Controlled through : Serial Port
*Documentation: [[Firegod]]

This is a modular system that supports 32 to 128 channels per serial port, in increments of 32 channels, with 100 levels of dimming (using pulse width modulation - PWM). It consists of a host controller module and one to four field modules. The SSRs are not included on these boards, and must be provided separately. The interface to this system is RS-232. This system is available on a coop basis from time to time, with the kits including the boards, the parts, and pre-programmed microcontroller chips (PICs). This board is intermediate in complexity to build.

====Renard====
*Controlled through: Serial Port
*Documentation: [[Renard]]

This is another modular system that supports a varying number of channels, depending on baud rate selection. It supports 256 levels of dimming, and can be configured with or without PWM, or for use in DC applications. There are several coop boards available for this system with varying capabilities. It can be a fairly complex system because there are so many options. More information is available at the link listed above.

====Lynx====
*Controlled through: [[DMX]]
*Manual [[LYNX_Controller_Manual]]
The Lynx is a DIY dimmer design that uses [[DMX]] as its protocol but uses standard Cat5 cable for interconnections. It's designed to be similar to the layout of commercially available dimmers (LOR, AL, etc). It is an all in one unit that has its own power supply and SSR's built into it. You connect your DMX Cat5 and plug it in. Lights plug into female cord connections that exit from the board. It allows for a full 256 levels of dimming. The starting address is programmed via vixen. Since it uses the DMX protocol you can run 512 channels of Lynx on one DMX universe at 25ms timming.

In an effort to prevent variations in the design (leading to complications for the newer builders), insure that troubleshooting help can be provided, and keep the total cost as low as possible it is done as a modified coop. All the parts including the PCB and an enclosure are included. The necessary PIC microprocessor will come with the program preloaded so that the builder will not need a PIC programmer. A detailed instruction manual with pictures is included and should allow anyone with basic soldering skills to successfully build the controller.

====Helix====
*Controlled through: Standalone
*Documentation: [[Helix]]

The Helix is a standalone, networkable, modular system that supports a virtually unlimited number of channels. It supports 256 levels of PWM dimming. A Helix system consists of a Helix Main board and up to three Helix Daughter boards. Each Main board and Daughter board can control up to 32 channels. The Main board and basic Daughter board uses the standard four channel SSR boards. There is a 32ch SSR Daughter board that has the SSRs integrated with a basic Daughter board. If more than 128 channels are needed another Helix system can be added to form a Helix Network. These systems stay sync’d via a wireless XBee link. Up to 251 additional Helix systems can be added to the Helix Network as long as they are within radio range of the first Helix system. This allows up to 32,128 channels in a pure Helix system.

Since it is a standalone system, the Helix is a fairly complex system to build and operate. In an effort to minimize the complexity, the design and firmware are configuration controlled by the original system designer, Gregory Bartlett (gmbartlett). The PCBs and preprogrammed EEPROMs are available from him. All PCBs are bare except for the Helix Main Board. Since it requires a surface mount microSD card socket, this part comes presoldered.

===Other Controllers (Signs, Servos, etc.)===
====Ledtriks====
*Controlled through: Parallel Port
*Documentation: [[LedTriks Controller Assembly Instructions]] [http://www.christmasinshirley.com/wiki/images/8/8e/LEDTriks_Wiring_Schematic.pdf LedTriks Wiring Diagram]

This is a controller to control low-voltage LED panels, designed by Robert Jordan. These panels are typically 16 LEDs high by 48 LEDs wide, for a total of 768 LEDs. Vixen can control up to four panels through one parallel port, and can even display text.

====Triks-C====
*Controlled through: Serial port or standalone
*Documentation: [[TRIKSC]], [http://www.christmasinshirley.com/wiki/index.php?title=Image:TRIKSC_CONTROLLER_v.0.1_manual.pdf Manual in PDF format]

This is a an add on controller/process for the Ledtricks. One of the problems with the original LEDTRIKS design was the load placed on the PC to chunk the data out the parallel port. The TRIKS-C uses a ATMEL process to take a LEDSTRIKS file and send it out to the LEDTRIKS Controller, via the serial prot.

====JEC Pixel Displays====
*Controlled through: [[DMX]]

Pixels are a stand-alone lighting fixture controlled by DMX-512. Each pixel has banks of red, green and blue wide-angle LEDs, currently six of each. Firmware is available in two versions: 3 and 4 channel. 3 channel requires a dmx channel for red, green and blue intensity. Four channel adds master intensity control to the original three.

Pixels require a stiff +12v switching power supply. Each circuit board draws ~ 130 mA at full brightness. Pixels chain together using standard CAT5 networking cable. Per the DMX spec, no more than 32 pixels should be connected together without using an optosplitter / signal buffer.

LED refresh rate is nearly 100 Hz.

More details can be found at http://www.response-box.com/rgblights

Currently in progress is a version of the firmware which will allow the DMX address to be changed in the field. Currently the address is hard-coded.

====rgbLED====
* Controlled through: Serial Port

The RGB LED's will have the ability to make hundreds of colors with a single led. They can be controlled individually, series, or parallel with each other. These are not able to be addressable individually as they have no control onboard. You will have to use DCSSR's, Franks Ren24LV, or a Grinch to turn each channel on and off to get the desired color. Each RGB LED will use 3 channels, 1 for each color. These would give you the ability to make strings out of these to have any color you want. It will also use less power compared to standard mini lights.

More information to follow as I start my testing.

DMX to Grinch/595 convertor

By Robert P Martin aka [http://www.doityourselfchristmas.com/forums/private.php?do=newpm&u=1269 RPM]

Like many others here, I too started out with a Grinch controller. It worked, but I soon realized that I wanted to have dimming, so this meant I had to spend more money and build another controller, or build my own dimming adapter and use my existing Grinch controller.

After looking at the options at the time, I decided to build my own dimming interface for my Grinch controller. I also wanted to use the DMX protocol, since I wanted to run my controller out in the yard some distance from my show computer in my garage, and by using DMX I could easily do this.

After a few months of trying different design prototypes, this is the design I came up with:

[[Image:Grinch_DMX_Dimmer_V2.jpg]]

[[Image:GrinchDMXdim_SCHEMATIC.JPG]]

I used this design in my display to run my Grinch controllers for my entire show the first year I ran a computerized show, and I continue to use it to run my 32 channel Megatree and it works very well, and best of all it dims! It also provides power for yor Grinch controller, so no other circuitry (other than a DMX dongle for your computer) is needed to run it.
Another plus about this design is it can also convert an Olsen 595 board to dimming as well!

This is brief a explanation of the operation:

JP1 is a termination jumper for the DMX signal. If this is the LAST device on the DMX line, put the jumper JP1 on it to terminate the 120 ohm resistor across the DMX buss. The DMX signal does not like to be unterminated, and if left unterminated it can do some strange things. If you have other DMX devices to hook up after this, plug them into this board and do not jumper JP1 the terminator on this board.

J1 on your Grinch controller should be jumpered so that the positive +5 side for operation will be provided through the RJ45 connector from the Grinch DMX dimmer adapter board.
This board uses what I call the "jumperless" method of setting the DMX start channel, so will also need to program the starting channel into the board before it will work.
It uses the sum of the first two DMX channels (channel 1 & 2) as the start channel address. This is done by powering the board off, then start vixen with the DMX plugin set for the all the channels. Set the intensity levels to use the 256 level mode not the 100% mode. Create a sequence of 3 seconds or more and set the first channel to the intensity value of the channel you want the board to use as the first channel for the whole 3 seconds so this is the only value output for this channel. If you want the board to start on a channel higher than 255 than simply add the additional to the second channel.

For example, to start at channel 300, the first channel is set to 255 and the second is set to 45. Now make sure vixen is set to repeat the sequence and start it. Now with the power still off on the board put the JP3 jumper on and power up the board for 3 seconds. The board will light LED1 and LED 2 solid to indicate that the programming has been saved.
Now turn power to the board off and remove JP3 (operation mode). Your board DMX start channel is now programmed. Remember in my example (channel 300) I would use vixens channel 300 - 364 to control my board now. If it doesn't act like you think it should, reprogram it to channel 1 and try it. An easy way to "default" the board back to a start channel of 1 is to place JP3 on and remove the DMX input cable, power the board on until LEDs 1 & 2 light solid, power off, remove JP3 and when you power back up it will be set back to start channel 1.

You can reprogram it as much as you like as the life of the EEPROM is over 1 million cycles, so you should have a hard time breaking it. It will remember the information for about 40 years with the power off so you don't have to reprogram it unless you want to change the channel assigned.

A standard straight through CAT5 cable should be used between the converter and the Grinch/595 board. This converter will run 64 channels, so you will need one converter per Grinch controller.

The distance from the converter to the Grinch/595 controller should be kept as short as possible. I use a 1 foot cable with mine and mount it in the same enclosure as my Grinch controller, although I have tested it with up to a 15 foot cable.

Parts cost is about $25-30 and I occasionally run co-op's for this PC board and I try to keep a few extras on hand. If you would like more information, you can PM me at username [http://www.doityourselfchristmas.com/forums/private.php?do=newpm&u=1269 RPM]

The GRINCH Controller

2010-04-17T06:58:39Z

RPM:

==Background==
:There are a myriad of computer based controller hardware available that will run under the Vixen software. While Robert Jordan was working on his LEDTRIKs, a LED panel based display, he noted that the same driver IC chip could replace two different types of chips used on the Olsen 595 COOP board.

:Robert’s aim was to come up with a circuit design for a controller that was smaller, cheaper, and easier to construct than the Olsen 595. He had to give it a name and decided on the ‘GRINCH’ after his favorite Christmas movie. The details of his prototype are detailed on the Computer Christmas website [http://computerchristmas.com/christmas/link-how_to/HowToId-118/Next_evolution_595_replacement here].

:The GRINCH does what you expect it to do – it makes lights flash under control of Vixen. It does not have Channel LEDs, it does not dim lights, and it does not use PICs. The GRINCH does work and it is cheap!

==The Board==
[[Image:Grinch Assy Step 7.jpg]]
[[Image:Grinch (top).jpg]]
==Simplified Theory==
:This is a real simplified explanation of how the data flow to the GRINCH works.

:The VIXEN program controls all data communication between the PC and the GRINCH.

:VIXEN uses the DATA BIT0 pin (pin 2) of the parallel port to serially feed data to RJ45 IN connector pin 8 on the GRINCH.

:VIXEN uses the STROBE pin (pin 1) of the parallel port for the clock signal to RJ45 IN connector pin 5 on the GRINCH.

:VIXEN uses the AUTOFEED pin (pin 14) of the parallel port for the strobe signal to RJ45 IN connector pin 7 on the GRINCH.

:VIXEN pumps out the channel data in reverse order, channel 64 first and channel 1 last (assuming a single GRINCH setup). This is due to how the data is clocked thru the serial shift register section of the IC chips. As VIXEN sends out data for each channel, it will also send out a corresponding clock signal so that the data can be clocked into the IC chips. At this point the data is only being held in the IC chips and the outputs of the chips will not change. Once all the data has been sent to the GRINCH, then VIXEN will send out a strobe signal followed by another clock and that will latch the data in the IC chips to the output pins. This process is repeated whenever VIXEN needs to update any channel data.

:A key thing to remember is that when VIXEN shows a channel as ON, the corresponding output pin of the GRINCH will be sinking signal and not a sourcing signal. This means for every channel that should be ON you should have 0 VDC (GND) on the corresponding output pin. This sinking signal is what the SSR boards require to turn on the desired AC connection.

==Circuit Diagram==
:The schematic diagram for the GRINCH can be downloaded [http://www.doityourselfchristmas.com/forums/showthread.php?t=126 here].

:The circuit is based using four 16 bit constant current LED sink driver integrated circuits. Currently, these are the tested/proven and readily available IC chips for use on the Grinch board.

::*MBI5026GN & MBI5027GN - available from [http://www.kingelectronics.com King Electronics]
::*A6279A – available from [http://www.allegromicro.com Allegro Microsystems]

:'''Differences between the IC chips:'''
::*Recommended Operating Voltage Range (VDD):
::**MBI chips = 4.5 – 5.5 VDC
::**Allegro chips = 3.0 – 5.5 VDC

:<blockquote>'''What this means to you:''' The Allegro chip is more tolerant of operating at a lower VDD. So if you are having problems detecting the signals coming from your PC’s parallel port you can lower your VDD and it might solve the problem.</blockquote>

::*Incoming voltage level for a valid HIGH signal:
::**MBI chips = 80% of VDD
::**Allegro chips = 70% of VDD

:<blockquote>'''What this means to you:''' If you are supplying 5 VDC to the GRINCH as the VDD, then your PC must have at least a 4 VDC signal out of the parallel port to properly trigger the MBI chips and at least 3.5 VDC to trigger the Allegro chips.</blockquote>

==Connection==
:The GRINCH is connected to the controlling PC via a cable from the PC’s parallel port to the RJ45 IN connector on the GRINCH.

[[Image:Grinch cable.jpg]]

:Multiple GRINCH boards can be daisy chained together by connecting the RJ45 OUT connector of the first GRINCH board to the RJ45 IN connector of the next GRINCH board.

==Powering the GRINCH==
:The GRINCH requires an external power source to operate. The normal voltage requirement for a single GRINCH would be 5 VDC at about 1 Amp. There are two options for applying power to the GRINCH.

::*Option 1: Apply the external power directly to J2, pin 1 – 5 VDC and pin 2 – GND

::*Option 2: Bring external power in via the RJ45 IN connector on pin 1 (5 VDC) and pin 3 (GND). With this method you would also need to place a shunt (jumper) on J1.

:There are many options of what to use for the external power source. Some users prefer to use an unused hard drive power connection inside the computer that is being used to run VIXEN. Others prefer to use an old computer power supply that they modify to run as a stand-alone power supply. And there are others that have had success in using wall-warts but care should be used with wall-warts since not all of them provide a regulated/filtered output.

:When connecting multiple GRINCH boards together you must have a shunt (jumper) on J1 for both boards being connected to allow the operating voltage to be passed from board to board.

==Computer Setup==
:'''BIOS Settings'''
::*The GRINCH appears to work best (for most users) if the parallel port is set to EPP in the computer BIOS. If you can't get it to work in EPP mode, try all other possible modes to see what works on your computer.

:'''VIXEN Settings'''
::*The GRINCH uses the OLSEN 595 plug-in.

==Layout==
:This image illustrates a simplified depiction of how a typical display using the GRINCH would be configured.
[[Image:Grinch Layout.jpg]]
:The GRINCH needs to be fairly close (less than 30ft) to the controlling computer due to the signal strength out of the parallel port.

:The SSRs can be placed anywhere needed in the display. They can be placed right next to the GRINCH or as far away as 800ft (farthest known test done).

==Setup for Beginners and Troubleshooting==
:If you are unsure that you have built your hardware correctly, you should follow the procedures contained in the [[Beginners Setup Guide The Grinch | Grinch Beginners Setup Guide]]. These procedures will guide you through the steps to help setup the hardware for the first time.

:If you encounter any problems with your Grinch, you can go to the [[Troubleshooting Guide The Grinch | Grinch Troubleshooting Guide]]. This page contains a methodical process to try to isolate problems/malfunctions and gives suggestions of what to do to fix them.

==Upgrades==
:'''Dimming'''
::*The GRINCH can be made to do dimming by adding the REN-T and REN-C boards to the setup. More details on how these boards operate can be found on their wiki pages.

:'''DMX512 Communication with Dimming'''
::*A DMX512 converter is available that will create the required signals and power for the GRINCH controller using a DMX512 signal and provide 64 channels of dimming. More info can be found [[DMX_to_Grinch/595_convertor|HERE]].

The GRINCH Controller

2010-04-17T06:50:50Z

RPM: Undo revision 3657 by RPM (Talk)

==Background==
:There are a myriad of computer based controller hardware available that will run under the Vixen software. While Robert Jordan was working on his LEDTRIKs, a LED panel based display, he noted that the same driver IC chip could replace two different types of chips used on the Olsen 595 COOP board.

:Robert’s aim was to come up with a circuit design for a controller that was smaller, cheaper, and easier to construct than the Olsen 595. He had to give it a name and decided on the ‘GRINCH’ after his favorite Christmas movie. The details of his prototype are detailed on the Computer Christmas website [http://computerchristmas.com/christmas/link-how_to/HowToId-118/Next_evolution_595_replacement here].

:The GRINCH does what you expect it to do – it makes lights flash under control of Vixen. It does not have Channel LEDs, it does not dim lights, and it does not use PICs. The GRINCH does work and it is cheap!

==The Board==
[[Image:Grinch Assy Step 7.jpg]]
[[Image:Grinch (top).jpg]]
==Simplified Theory==
:This is a real simplified explanation of how the data flow to the GRINCH works.

:The VIXEN program controls all data communication between the PC and the GRINCH.

:VIXEN uses the DATA BIT0 pin (pin 2) of the parallel port to serially feed data to RJ45 IN connector pin 8 on the GRINCH.

:VIXEN uses the STROBE pin (pin 1) of the parallel port for the clock signal to RJ45 IN connector pin 5 on the GRINCH.

:VIXEN uses the AUTOFEED pin (pin 14) of the parallel port for the strobe signal to RJ45 IN connector pin 7 on the GRINCH.

:VIXEN pumps out the channel data in reverse order, channel 64 first and channel 1 last (assuming a single GRINCH setup). This is due to how the data is clocked thru the serial shift register section of the IC chips. As VIXEN sends out data for each channel, it will also send out a corresponding clock signal so that the data can be clocked into the IC chips. At this point the data is only being held in the IC chips and the outputs of the chips will not change. Once all the data has been sent to the GRINCH, then VIXEN will send out a strobe signal followed by another clock and that will latch the data in the IC chips to the output pins. This process is repeated whenever VIXEN needs to update any channel data.

:A key thing to remember is that when VIXEN shows a channel as ON, the corresponding output pin of the GRINCH will be sinking signal and not a sourcing signal. This means for every channel that should be ON you should have 0 VDC (GND) on the corresponding output pin. This sinking signal is what the SSR boards require to turn on the desired AC connection.

==Circuit Diagram==
:The schematic diagram for the GRINCH can be downloaded [http://www.doityourselfchristmas.com/forums/showthread.php?t=126 here].

:The circuit is based using four 16 bit constant current LED sink driver integrated circuits. Currently, these are the tested/proven and readily available IC chips for use on the Grinch board.

==Connection==
:The GRINCH is connected to the controlling PC via a cable from the PC’s parallel port to the RJ45 IN connector on the GRINCH.

:Multiple GRINCH boards can be daisy chained together by connecting the RJ45 OUT connector of the first GRINCH board to the RJ45 IN connector of the next GRINCH board.

==Powering the GRINCH==
:The GRINCH requires an external power source to operate. The normal voltage requirement for a single GRINCH would be 5 VDC at about 1 Amp. There are two options for applying power to the GRINCH.

::*Option 1: Apply the external power directly to J2, pin 1 – 5 VDC and pin 2 – GND

::*Option 2: Bring external power in via the RJ45 IN connector on pin 1 (5 VDC) and pin 3 (GND). With this method you would also need to place a shunt (jumper) on J1.

:There are many options of what to use for the external power source. Some users prefer to use an unused hard drive power connection inside the computer that is being used to run VIXEN. Others prefer to use an old computer power supply that they modify to run as a stand-alone power supply. And there are others that have had success in using wall-warts but care should be used with wall-warts since not all of them provide a regulated/filtered output.

:When connecting multiple GRINCH boards together you must have a shunt (jumper) on J1 for both boards being connected to allow the operating voltage to be passed from board to board.

==Computer Setup==
:'''BIOS Settings'''
::*The GRINCH appears to work best (for most users) if the parallel port is set to EPP in the computer BIOS. If you can't get it to work in EPP mode, try all other possible modes to see what works on your computer.

:'''VIXEN Settings'''
::*The GRINCH uses the OLSEN 595 plug-in.

==Layout==
:This image illustrates a simplified depiction of how a typical display using the GRINCH would be configured.
[[Image:Grinch Layout.jpg]]
:The GRINCH needs to be fairly close (less than 30ft) to the controlling computer due to the signal strength out of the parallel port.

:The SSRs can be placed anywhere needed in the display. They can be placed right next to the GRINCH or as far away as 800ft (farthest known test done).

DMX to Grinch/595 convertor

2010-04-17T06:50:14Z

RPM:

By Robert P Martin aka RPM

Like many others here, I too started out with a Grinch controller. It worked, but I soon realized that I wanted to have dimming, so this meant I had to build another controller, or build my own dimming adapter.

After looking at the options at the time, I decided to build my own dimming interface for my Grinch controller. I also wanted to use the DMX protocol, since I wanted to run my controller out in the yard some distance from my show computer in my garage, and by using DMX I could easily do this.

After a few months of trying different design prototypes, this is the design I came up with:

[[Image:Grinch_DMX_Dimmer_V2.jpg]]

[[Image:GrinchDMXdim_SCHEMATIC.JPG]]

I used this design in my display to run my Grinch controllers for my entire show the first year I ran a computerized show, and I continue to use it to run my 32 channel Megatree and it works very well, and best of all it dims!

This is brief a explanation of the operation:

JP1 is a termination jumper for the DMX signal. If this is the LAST device on the DMX line, put the jumper JP1 on it to terminate the 120 ohm resistor across the DMX buss. The DMX signal does not like to be unterminated, and if left unterminated it can do some strange things. If you have other DMX devices to hook up after this, plug them into this board and do not jumper JP1 the terminator on this board.

J1 on your Grinch controller should be jumpered so that the positive +5 side for operation will be provided through the RJ45 connector from the Grinch DMX dimmer adapter board.
This board uses what I call the "jumperless" method of setting the DMX start channel, so will also need to program the starting channel into the board before it will work.
It uses the sum of the first two DMX channels (channel 1 & 2) as the start channel address. This is done by powering the board off, then start vixen with the DMX plugin set for the all the channels. Set the intensity levels to use the 256 level mode not the 100% mode. Create a sequence of 3 seconds or more and set the first channel to the intensity value of the channel you want the board to use as the first channel for the whole 3 seconds so this is the only value output for this channel. If you want the board to start on a channel higher than 255 than simply add the additional to the second channel.

For example, to start at channel 300, the first channel is set to 255 and the second is set to 45. Now make sure vixen is set to repeat the sequence and start it. Now with the power still off on the board put the JP3 jumper on and power up the board for 3 seconds. The board will light LED1 and LED 2 solid to indicate that the programming has been saved.
Now turn power to the board off and remove JP3 (operation mode). Your board DMX start channel is now programmed. Remember in my example (channel 300) I would use vixens channel 300 - 364 to control my board now. If it doesn't act like you think it should, reprogram it to channel 1 and try it. An easy way to "default" the board back to a start channel of 1 is to place JP3 on and remove the DMX input cable, power the board on until LEDs 1 & 2 light solid, power off, remove JP3 and when you power back up it will be set back to start channel 1.

You may reprogram it as much as you like the life of the EEPROM is over 1 million cycles so you should have a hard time breaking it. It will remember the information for about 40 years with the power off so you dont have to reprogram it unless you want to change the channel assigned.

A straight through cable should be used between the converter and the Grinch/595 board. This converter will run 64 channels, so you will need one converter per Grinch controller.

The distance from the converter to the Grinch/595 should be as short as possible. I use a 1 foot cable with mine and mount it in the same enclosure as my Grinch controller.

==Overview of DIY Hardware Approaches That Work With Vixen==

This section provides information about Do-It-Yourself (DIY) hardware that works with the [[Vixen]] software program. Vixen is a Windows (.NET Framework 2) program that runs on a PC, and is used to create and run light shows that may be synchronized to music. Here is a brief list of the DIY approaches that you can take that will work with Vixen.

===Non-Dimmable Light Controllers===

====SSR Direct Attach====

* Controlled through: Parallel Port
* Documentation: [[Solid State Relays]]

If you need 12 or fewer channels, you can just buy or build SSRs and connect them to the parallel port on your PC, and use them to turn 110VAC light strings (or just plain lamps) on and off (no dimming). These ssrs must be sourced or positive switched. From time to time there are coop buys of SSR boards,but these are usually sinked, and/or parts, to reduce your expense. You could place a couple ULN2803s and use the coop sinked ssrs. For more information on this come over to the forum and/or ask on the LiveChat.

====Kit74====
*Controlled through: Parallel Port

This is a kit with mechanical relays that can be purchased from various places. It is similar to the SSR Direct Attach, although the mechanical relays are noisy and have a limited lifespan. There are probably other similar kits available as well.

====Hill320====
* Controlled through: Parallel Port
* Documentation: http://computerchristmas.com/christmas/link-how_to/HowToId-4/How_To_Build_A_Parallel_Port_Controller_Box

This is a controller originally designed by Hill Robertson http://computerchristmas.com to allow up to 320 channels to be controlled by a PC, and requires an external power supply and SSRs. There isn't any coop board for this design at the moment. It is a more complicated design, and it is not currently recommended for newbies.

====Olsen 595/Grinch====
*Controlled through: Parallel Port
*Documentation: [[The GRINCH Controller]], [[GRINCH Controller Assembly Instructions]]
*Documentation: [[Olsen 595]]

This is a popular controller based on an approach first popularized on the http://computerchristmas.com and/or http://planetchristmas.com forums by Peter Olsen. In its first incarnation it used 8-bit 74HC595 logic chips, often with external buffers, while a later design (Grinch), popularized by Robert Jordan, uses 16-bit chips specialized for this use. There are coop boards available for both of these designs. These coop boards need external power supplies, and work with external (coop) SSR boards to control AC lighting.

There are some variations of this approach that support dimming, but they are not as popular and there aren't any coop boards available. However, using a [[Ren-C]] board can add dimming capability to a 595 or Grinch, which causes the board to operate as a Renard board. There is also an option available to run a Grinch or 595 controller from DMX with dimming.

The Grinch board is a good choice if you need more than 12 channels but want a board that is simple to build. It doesn't use very many parts, and is easy to assemble.

===Dimmable Light Controllers===
====Firegod====
*Controlled through : Serial Port
*Documentation: [[Firegod]]

This is a modular system that supports 32 to 128 channels per serial port, in increments of 32 channels, with 100 levels of dimming (using pulse width modulation - PWM). It consists of a host controller module and one to four field modules. The SSRs are not included on these boards, and must be provided separately. The interface to this system is RS-232. This system is available on a coop basis from time to time, with the kits including the boards, the parts, and pre-programmed microcontroller chips (PICs). This board is intermediate in complexity to build.

====Renard====
*Controlled through: Serial Port
*Documentation: [[Renard]]

This is another modular system that supports a varying number of channels, depending on baud rate selection. It supports 256 levels of dimming, and can be configured with or without PWM, or for use in DC applications. There are several coop boards available for this system with varying capabilities. It can be a fairly complex system because there are so many options. More information is available at the link listed above.

====Lynx====
*Controlled through: [[DMX]]
*Manual [[LYNX_Controller_Manual]]
The Lynx is a DIY dimmer design that uses [[DMX]] as its protocol but uses standard Cat5 cable for interconnections. It's designed to be similar to the layout of commercially available dimmers (LOR, AL, etc). It is an all in one unit that has its own power supply and SSR's built into it. You connect your DMX Cat5 and plug it in. Lights plug into female cord connections that exit from the board. It allows for a full 256 levels of dimming. The starting address is programmed via vixen. Since it uses the DMX protocol you can run 512 channels of Lynx on one DMX universe at 25ms timming.

In an effort to prevent variations in the design (leading to complications for the newer builders), insure that troubleshooting help can be provided, and keep the total cost as low as possible it is done as a modified coop. All the parts including the PCB and an enclosure are included. The necessary PIC microprocessor will come with the program preloaded so that the builder will not need a PIC programmer. A detailed instruction manual with pictures is included and should allow anyone with basic soldering skills to successfully build the controller.

====Helix====
*Controlled through: Standalone
*Documentation: [[Helix]]

The Helix is a standalone, networkable, modular system that supports a virtually unlimited number of channels. It supports 256 levels of PWM dimming. A Helix system consists of a Helix Main board and up to three Helix Daughter boards. Each Main board and Daughter board can control up to 32 channels. The Main board and basic Daughter board uses the standard four channel SSR boards. There is a 32ch SSR Daughter board that has the SSRs integrated with a basic Daughter board. If more than 128 channels are needed another Helix system can be added to form a Helix Network. These systems stay sync’d via a wireless XBee link. Up to 251 additional Helix systems can be added to the Helix Network as long as they are within radio range of the first Helix system. This allows up to 32,128 channels in a pure Helix system.

Since it is a standalone system, the Helix is a fairly complex system to build and operate. In an effort to minimize the complexity, the design and firmware are configuration controlled by the original system designer, Gregory Bartlett (gmbartlett). The PCBs and preprogrammed EEPROMs are available from him. All PCBs are bare except for the Helix Main Board. Since it requires a surface mount microSD card socket, this part comes presoldered.

===Other Controllers (Signs, Servos, etc.)===
====Ledtriks====
*Controlled through: Parallel Port
*Documentation: [[LedTriks Controller Assembly Instructions]] [http://www.christmasinshirley.com/wiki/images/8/8e/LEDTriks_Wiring_Schematic.pdf LedTriks Wiring Diagram]

This is a controller to control low-voltage LED panels, designed by Robert Jordan. These panels are typically 16 LEDs high by 48 LEDs wide, for a total of 768 LEDs. Vixen can control up to four panels through one parallel port, and can even display text.

====Triks-C====
*Controlled through: Serial port or standalone
*Documentation: [[TRIKSC]], [http://www.christmasinshirley.com/wiki/index.php?title=Image:TRIKSC_CONTROLLER_v.0.1_manual.pdf Manual in PDF format]

This is a an add on controller/process for the Ledtricks. One of the problems with the original LEDTRIKS design was the load placed on the PC to chunk the data out the parallel port. The TRIKS-C uses a ATMEL process to take a LEDSTRIKS file and send it out to the LEDTRIKS Controller, via the serial prot.

====JEC Pixel Displays====
*Controlled through: [[DMX]]

Pixels are a stand-alone lighting fixture controlled by DMX-512. Each pixel has banks of red, green and blue wide-angle LEDs, currently six of each. Firmware is available in two versions: 3 and 4 channel. 3 channel requires a dmx channel for red, green and blue intensity. Four channel adds master intensity control to the original three.

Pixels require a stiff +12v switching power supply. Each circuit board draws ~ 130 mA at full brightness. Pixels chain together using standard CAT5 networking cable. Per the DMX spec, no more than 32 pixels should be connected together without using an optosplitter / signal buffer.

LED refresh rate is nearly 100 Hz.

More details can be found at http://www.response-box.com/rgblights

Currently in progress is a version of the firmware which will allow the DMX address to be changed in the field. Currently the address is hard-coded.

====rgbLED====
* Controlled through: Serial Port

The RGB LED's will have the ability to make hundreds of colors with a single led. They can be controlled individually, series, or parallel with each other. These are not able to be addressable individually as they have no control onboard. You will have to use DCSSR's, Franks Ren24LV, or a Grinch to turn each channel on and off to get the desired color. Each RGB LED will use 3 channels, 1 for each color. These would give you the ability to make strings out of these to have any color you want. It will also use less power compared to standard mini lights.

More information to follow as I start my testing.

Up to 251 additional Helix systems can be added to the Helix Network as long as they are within radio range of the first Helix system. This allows up to 32,128 channels in a pure Helix system.

Since it is a standalone system, the Helix is a fairly complex system to build and operate. In an effort to minimize the complexity, the design and firmware are configuration controlled by the original system designer, Gregory Bartlett (gmbartlett). The PCBs and preprogrammed EEPROMs are available from him. All PCBs are bare except for the Helix Main Board. Since it requires a surface mount microSD card socket, this part comes presoldered.

===Other Controllers (Signs, Servos, etc.)===
====Ledtriks====
*Controlled through: Parallel Port
*Documentation: [[LedTriks Controller Assembly Instructions]] [http://www.christmasinshirley.com/wiki/images/8/8e/LEDTriks_Wiring_Schematic.pdf LedTriks Wiring Diagram]

This is a controller to control low-voltage LED panels, designed by Robert Jordan. These panels are typically 16 LEDs high by 48 LEDs wide, for a total of 768 LEDs. Vixen can control up to four panels through one parallel port, and can even display text.

====Triks-C====
*Controlled through: Serial port or standalone
*Documentation: [[TRIKSC]], [http://www.christmasinshirley.com/wiki/index.php?title=Image:TRIKSC_CONTROLLER_v.0.1_manual.pdf Manual in PDF format]

This is a an add on controller/process for the Ledtricks. One of the problems with the original LEDTRIKS design was the load placed on the PC to chunk the data out the parallel port. The TRIKS-C uses a ATMEL process to take a LEDSTRIKS file and send it out to the LEDTRIKS Controller, via the serial prot.

====JEC Pixel Displays====
*Controlled through: [[DMX]]

Pixels are a stand-alone lighting fixture controlled by DMX-512. Each pixel has banks of red, green and blue wide-angle LEDs, currently six of each. Firmware is available in two versions: 3 and 4 channel. 3 channel requires a dmx channel for red, green and blue intensity. Four channel adds master intensity control to the original three.

Pixels require a stiff +12v switching power supply. Each circuit board draws ~ 130 mA at full brightness. Pixels chain together using standard CAT5 networking cable. Per the DMX spec, no more than 32 pixels should be connected together without using an optosplitter / signal buffer.

LED refresh rate is nearly 100 Hz.

More details can be found at http://www.response-box.com/rgblights

Currently in progress is a version of the firmware which will allow the DMX address to be changed in the field. Currently the address is hard-coded.

====rgbLED====
* Controlled through: Serial Port

The RGB LED's will have the ability to make hundreds of colors with a single led. They can be controlled individually, series, or parallel with each other. These are not able to be addressable individually as they have no control onboard. You will have to use DCSSR's, Franks Ren24LV, or a Grinch to turn each channel on and off to get the desired color. Each RGB LED will use 3 channels, 1 for each color. These would give you the ability to make strings out of these to have any color you want. It will also use less power compared to standard mini lights.

More information to follow as I start my testing.
