View Full Version : 2 channel learning prop controller

I have been working on a Halloween prop controller and so far things look very good. It is still in prototyping stages but the I believe concept is solid enough to share with the community. This controller uses a PIC12f683 micro controller, 3 push button switches, 2 relays and a few other parts. Cost to build will be around $6. Basically how it works is you push a record button then tap in the timing sequence you want the 2 channels to come on and off. Record time is 102 seconds and the sequence is saved to the EEPROM so it will remain stored even after power is unhooked from the board. Here is a video of my prototype in action.

I hope this is inexpensive to build. I have worked for a haunted house for many years and we have several devices like this. They are called the Maestro II
http://www.halloweenfxprops.com/animation-maestro-ii, they work just like you show but can handle any voltage put through their build in relays. As you can see from the link, they are not cheap. This may be a much cheaper solution. Keep going!

The relays I have on order but are currently untested are good for 120v@10 amp. Max current draw will be limited by the PCB but I think we should be able to get somewhere near 5 amps each channel. The cost of the circuit shown in the video was under $3. by the time we add in relays and voltage regulator it should be up to around $6. The PIR used in the video will set you back about $3. Of course this one is DIY so you have to put it all together yourself. Even if you have to buy a soldering station and PICkit2 I believe you would still be money ahead on the 1st one compare to the out of the box solution.

Just a quick update. I did all the parts I need to complete this board have been shipped and I expect to have one built and tested by the end of this week or early next week. The board layout is near complete. I'm trying to make this a 100% Tayda Electronics build to keep price low. Some of the part numbers Tayda gives are not listed as components in Eagle so I tried to look at the datasheets provided and choose similar footprint parts. As soon as I get all the needed parts I will build one to make sure that everything fits and works as it should. I have attached a PDF of the board layout. As always question, comments, and criticisms are welcome.

The silk screen likely has several errors at this point. My main concern at this point on the board layout is the copper layer. I will go back and clean up the silkscreen after I test the board. Make it work first then make it look good is my way of thinking.


Oh, I meant to ask; did you use all of the bits in each EE byte for channel data?

Yes, Four events are stored per byte of EEPROM. A bit 1 is channel on a bit of 0 is channel off. Event 1 is stored in bits 7 and 6 event 2 is stored in bits 5 and 4. Event 3 is stored in bits 3 and 2. Event 4 is stored in bits 1 and 0. By using this method I can store 1024 total events in only 256 bytes of ram. Each event period last 100 ms for a total of 102.4 seconds of record time.

09-01-2012, 11:31 PM
Ah, that's what I thought. I made something similar a while back, but that used one byte per step as it had 8 channels.

For the relays, you could get better mains to ELV clearance by choosing relays that don't have the common between the coil terminals.

Thank you for the suggestion David. I really am glad to see that you are looking out for my best interest and I agree that a different choice of relay would provide more clearance. However I believe that this design does provide sufficient clearance. I think that this will be used mostly for 12 volt applications. Things like wiper motors, vent motors and pneumatic solenoid valves. Although if you wanted to use 120 volt reindeer motors or lights that is certainly possible. Lets also remember what we are isolating from the possible high voltage. This controller is not connected to a PC worth thousands of dollars it uses a micro controller that only cost $1.30. Heck the whole circuit comes in at $4.65 so In the very unlikely event that water would get on the board and cause a short its not a real big loss. My plan is to move forward with current design. Again, thank you for your interest and I'm glad to see people are taking time to look at the circuit well enough to see these things and point them out.

No problems. I wasn't sure of the intended loads so thought I'd chime in.

There are a few improvements I'd do layout wise, but as a hobby design it's pretty good overall. :)

Just a quick update. All parts have arrived and they do fit testing is underway and all initial this for this 2 channel board look great. I will get the etch files and firmware cleaned up and upload them to the copper section of the File Library hopefully within the next few days.

I have also been working on a similar similar controller that has 4 channels of relay output and stereo MP3 sound output. The 4 channel board still needs some work to get the MP3 playing correctly I hope to get the firmware working soon. This board should cost around $20 to build including the MP3 player module. Here are a few pictures of the 4 channel board currently under development.

Files for the 2 channel version of this board have been added to the copper section of the File Library (http://doityourselfchristmas.com/forums/dynamics/showentry.php?e=189&catid=8). Cost to build this one is about $5.

I have not started documentation on these boards yet. I'm not sure if or when I will have time to properly document these. My feeling is that the design is simple enough that most people that are willing to tackle a home etch will most likely have the skill required to get it up and running without a step by step assembly guide. I do plan to at the very least put together a brief description of operation. If you have any questions please feel free to ask and I will do what I cant to assist you.

I'm not sure if anybody has built or is planing to build these controllers. I see the files have been downloaded a few times so for anybody who is building, waiting for parts, or just thinking about it. I have a short video that shows the operation of the 4 channel controller. I still have not made a prop to control yet but maybe this will give you guys an idea of how it works.

Etching the PCB is really easy once you get the hang of it. There is tons of info both here and on the net to help you get started. I know there is a thread that Dirk put a lot of time into with pictures and a great written how to but I cant seem to locate it right now. I know there are a few people that would like production boards but I simply do not have the extra time or cash to make it happen this year. I wish you the best of luck with you ground breaker prop and hope you find this little controller useful.

I have had enough interest in the 4 channel version of this board to move forward with at least a small run of production PCBs. I would like to get a feel for how many boards to order. So, please post any interest you have in this thread. I know its late in the year to start Halloween so please think of this as a for next year project. I can't promises delivery before Halloween. The etch files are still available for anyone needing to get one together real quick.

The board has changed slightly from the home etch version but functionally will be the same. Going to a two sided board has allowed me to add a headphone jack for the audio output rather than the 3 pin header. Max current has been increased to 10 amps on each channel. I have attached .pdf files of the proposed board layout.

A huge thanks goes out to Mactayl for helping iron out the final board layout and to scubaspookf and the rest of the guys over at SOP for the high interest to make this happen.

I'm currently getting quotes on PCB prices so I don't know for sure yet. But, these boards are close to the same size as the Simple 32 so my best guess at this point would be a similar price of about $10 each. Keep in mind that the order for these will certainly be a smaller quantity than the Simples so that may affect the price a bit.

Yes PCB only. You can get the BOM from Tayda electronics for about $9 I need to adjust a few things in the BOM from the home etch version because there are a few changes. The MP3 module is available from MDfly.com for about $10. You will also need some sort of 12 VDC power source, an SD card to store the MP3 files on, and some sort of external trigger(PIR sensor, reed switch, push button, ect.) I have been testing with this PIR sensor (http://www.suntekstore.com/goods-14001941-pyroelectric_infrared_pir_motion_sensor_detector_m odule.html) with great results or you can get them for even less money five at a time (http://www.suntekstore.com/goods-14002005-5x_pyroelectric_infrared_pir_motion_sensor_detecto r_module.html)

I was toying with the idea of 8 channels on an 18F2525 because it has a large amount of EEPROM space. The biggest hurtle I see is physical board space will not fit within the free version of Eagle. Maybe a daughter board to make use of the future expansion header on the Simple Renard 8 :hmm:

Consider Diptrace, Tyler. No size limitation -- free version can have up to 400 holes I believe; they also can set you up with a "non-profit" version since this is a DIY type of site, and that extends the limitation to 500 holes. Using surface mount, I guess there'd be no limitation at all!

tstraub
10-13-2012, 06:54 AM
I have made some changes to the firmware on this controller. The new firmware adds an options menu to select longer record times and to enable a re trigger delay. You can now select up to four minute sequence length. The catch is at four minute record time the switch sample rate is nearly 500 ms. I don't think this is too big of a problem. If a prop takes 4 minutes to complete its action I think a half second timing error is acceptable.

The re-trigger delay is a sequence of 4 timers that can be enabled in any combination you want. the timers are 1 minute, 2 minute, 3 minute, and 4 minute timers. If you want a 10 minute delay between possible triggering events enable all 4 timers. if you need 7 minutes enable the 3 and 4 minute timers. the ambient audio track is played once before the delay and not restarted during the delay so if you are using an ambient audio track and a trigger delay the audio file must be at least as long as the delay time. Just use your favorite MP3 editing software to loop the audio enough times to extend the file length

I'm not sure how many of these have been built, maybe just the three I etched? Anyway the etch files have been downloaded enough times that I believe there might be a few out there in the wild. The updated firmware is attached for anyone who wants to give it a try. Just flash the microchip and drag the 2 included MP3 files to the SD card. As always questions, comments, and criticisms are welcome.

Just a thought; If you used 1, 2, 4 & 8 minute values, you can have 1..15 minute timing. Alternatively make it 30s, 1m, 2m and 4m to get 00:30 to 7:30 in 30 sec increments.

Thanks for the suggestion David. I went by the numbers marked on the switches. Your timing increments would be a more efficient way to go. It eliminates the overlap of sum values. I like it, changes should be very easy.

Just a quick update. PCBs arrived this afternoon. I did populate one of them and testing has started. All initial test look good. I will torture this thing for a day or two and then is long as all goes well I plan start the dreaded documentation and have boards available very soon. I know the drill "without a picture it didn't really happen". So, enjoy the picture.

The BOM has changed slightly from the home etch version so please wait for the revised BOM if you plan to build this board.

The PCB dimensions are 3 3/4 in x 4 1/2 inches. The MP3 module sticks up about 1 3/4 inches from the PCB. There is a headphone jack on the right side of the board so you will need to leave room to plug in your audio cable. An inch would probably be enough if you use a right angle plug maybe 2-3 inches if using a straight plug.

I built one of Tyler's 4-channel Learning Controllers tonite, and it's really quite a nice project.

It's an easy build, the firmware works slick, and I can see how this little gizmo could be a very, very useful little tool! For example, controlling your fog machine so you don't have to monitor it, or maybe a fan that blows air over some blocks of ice to add a chill to the air where kids may walk... playing background sounds repeatedly through its sound card... Its relays will handle up to 10amps each so you can put some pretty hefty gear on it.

Only thing I'll suggest to folks is that the firmware ASM file has a blank space in its name. MPASM (or other compilers) don't like names with spaces so be sure to replace the space with an underscore bar or take it out altogether before you try to compile the firmware.

Nice job, Tyler! Now I have to go think up how I'm going to use this.... or where I might be able to use it in my Christmas display.... hmmmmm......

Here is a crazy idea I just thought of to work this controller into Christmas displays. Why not use it to animate your donation box. Ambient track could be a voice-over containing info about your charity. Trigger it off a micro switch or even a mercury switch attached to a flap that needs to be lifted to insert the donation. Then it switches to a Thank you audio track and flashes some lights. This way the person making the donation would recieve an instant thank you and get that warm and fuzzy feeling that there donation really did mean something.

Anyway just some rambling from a crazy man. Maybe someone will run with it.

OK Update:

I currently do have PCBs available for sale at hauntfourm. I have been putting off offering them here mostly because of lack of proper documentation. I just don't think it would be wise to sell sell a bunch of these and then be bombarded with questions that could be avoided simply by having the documentation available at the time it is needed. I have sold a few and the guys who have recieved them have been great about giving me feedback that should help make the documentation better.

I have also teamed up with another member of the forums to explore the possibility of offering a kit that will include the PCB, BOM, MP3 module, PIR sensor, and a 3 wire harness to connect the PIR to the controller. All you would have to come up with is an SD card, 12 volt power source and some sort of enclosure. We are still in the process of crunching the numbers to see if we can make this work.

In short if you are the type of person who would rather receive a kit with proper build instructions then I suggest that you wait and see what we can work out. but, If you are the type of person who would rater get to it right away and start building then head over to hauntforum and look for me in the vendors section to place your PCB order.

Gordy,
Did you register at Haunt Forum using this same name? I don't see that name coming up in the members list.
I'm a moderator over there so let me know if you have problems getting registered and I'll see if I can help get it taken care of.

Does someone know where the brd files are for this and the 4 channel controller?

Home etch able eagle files are in the copper section of the file library.

Four channel version is here http://doityourselfchristmas.com/forums/dynamics/showentry.php?e=188&catid=8

2 channel is here http://doityourselfchristmas.com/forums/dynamics/showentry.php?e=189&catid=8

I also have a few production PCBs for the 4 channel board on hand. If you want to take the easy way send me a PM and we'll work out the payment and shipping arrangements. BTW the production 4 channel board has a few improvements over the home etch. It has now has diodes on the input to protect it against accidental reverse polarity. And it has an optional wired remote controller to extend the buttons away from the controller. This is useful when using pneumatic cylinders to keep a safe distance away from moving parts or anytime you mount the controller in a place that has limited access.
