I'm confused? Is this for just the the LEDs? If so, what about Boards and other components such as Resistors and RJ-45 Connectors?

Frank's video is with half-populated strips btw.
I have a demo of them also - I was playing with the WinAMP plug-in for Halloween so the colors changes are a bit odd... forgive the camera work - it's a still-camera in video mode and it doesn't do the brightness justice:
http://www.vimeo.com/7323209
and from my 2009 show - this shows them off fairly well - a better camera was used this time but again - they are brighter in person:

You will want Common Anode if using a DCSSR (and I believe for Frank's LV as well).

Does anybody know for sure if the 24LV needs common anode or common cathode? Looks like common anode to me (setting ssr mode off sends (+) to pins 1,3,5,7, which would mean common anode, if I'm not mistaken?)

From my understanding you need a DC SSR to use the Super Strips fully populated on the 24LV correct. Can you get away half populated on the 24LV? thanks

So this co-op is for rgb only what would total be for everything i need to complete project want to make sure its worth it. Like the effect it makes just trying to determine if price per unit is not to much.
budude

First - regarding questions about the LV - - I suggest one of you PM Frank directly, get the answers and post back here. I do not believe the LV will drive a fully populated strip especially if you have Red + Blue on to make purple at full power and on multiple strips from the same ULN2803 - it just can't drive that much (it would >1A per chip easily...). In that case you should use a DCSSR (from the LV for example) which can easily drive a full strip no problem. Yes - it costs more but then so will the constant pile of ULN2803 chips you keep pulling out of the LV after smoking them...
wrt to the Strips - to FULLY populate them you need (I will talk in multiples of 3):
3 Strips - $12 (from Frank's store) + SH - let's call it $18
54 RGB LEDs - the group buy is for 60 so you get extras - $19+$6 or $25
54 White LEDs - guessing about half the cost of RGB - let's say $12
216 resistors of different values - I can get 100 at JameCo for $2 - let's say $10 w/SH
3 RJ45s - it's really 6 but if you aren't going to daisy-chain - which you can't with fully populated then you only need 3 - let's say $2
We can argue over actual pricing - but I think it's close enough - you're looking at about $67 or ~$22 per strip - let's call it $20 if you save on S&H here and there and you still need something to drive them (LV+DCSSR for example) and a power supply.

I have seen Frank post he is driving 2 off each cat5 from a Ren24lv, however he did not state whether the boards were fully populated.
Unfortunately there hasn't been a lot of documentation or questions on the forum about these. I will PM frank and get some more information.
I will also be looking at a white & warm white LED coop to start later tonight or tomorrow morning.
Unfortunately because of the different configurations possible and the different needs of the members of the board the coops are difficult to run. I be running the coops for the different LEDs. Once I have LEDs and boards I will looking at running a coop for the rest of the BOM after I have determined a good BOM using these LEDs running off a Ren24lv w/o SSRs which is how I am going to run mine. I will post back once I hear from Frank about the LEDs and the controllers.

I find that ... interesting ...
So - two half-pop strips is really one fully populated. That is 360mA (if using 20mA forward current on the LEDs to get full brightness...) - and that might be OK for a single ULN2803 for a single channel -- but the chip has 8 drivers so it's probably going to be driving two strips (RGB+W x 2) or 720mA and that's assuming you don't mix colors at all - which - if you did at full power would be 1440mA - I'd have to see it to believe it... I suppose if you were careful with your sequencing/mixing you might get it to work but...
I think it would be very important for someone to get his blessing one way or the other before anyone goes down a particular path... In either case, there is no loss going with the Ren24LV as the controller since it can drive DCSSRs as well...

Adding it all up ...
$19.00 (x 4 sets) + $13.00 is quite a bit more than the original guesstimate values of $15.75
It's only slightly cheaper than ordering direct from the Wholesaler. Given I want to order some additional WARM WHITE, and flat top LEDs, I think I'm going to be better off buying direct. Sorry to everyone else who may have been depending on me to help keep the numbers in check.

Look at post #5 - 15. (http://doityourselfchristmas.com/forums/showpost.php?p=67803&postcount=5) unfortunately Frank doesn't say whether his are half or fully populated. I have asked him and will let everyone know his reply.

The price in the other thread was based on the sellers new manufacturer. This price is based on the old proven manufacturer. This price is also based on an order of 1500. If we reach 2000 LEDs the price will come down.
Also, keep an eye out tomorrow for the white/warm white LED coop. I will be ordering all the LEDs at the same time and will combine RGB and White LEDs together which will (in most cases) eliminate additional shipping costs.

As budude pointed out, with each uln actually controlling (2) of the rj45's, I think it's reasonable that you could have 4 outputs conducting at the same time (ie r+b on rj45 #1 and r+b on rj45 #2). With 4 outputs on at the same time you have a max of about 260ma per output.
That would be 13 leds if you were driving each at 20ma.
If you half-populate each strip and have it on it's own rj45 I think you would be ok for any scenario.
If you fully populate or chain two half-populated I think you would have a problem if you weren't careful not to have 2 or more channels on 100% at the same time. Which I suppose is not a common occurance. Normally you would be fading one down while you fade another up, or mixing two colors at less than 100% to make some other color. If you were planning on making white by turning rgb on at the same time rather than putting the white leds in, I think you would have trouble.
Skunberg

Frank's are half populated w/ two tied together. He also has only the RGB (no white) and mentioned not exceeding full power of one color, so if two color are running they need to be half power each. This information is from a mix of his website, test video, more than one thread and a couple PM's last year.
I'm planning to half populate and one strip per rj45 off the Ren24LV so I can add some white and not be as close to the edge as Frank. Not to mention being able to chase like budude. Subject to change from this years discussion. Is that clear as mud?

The strips don't care - they can use use common anode or common cathode but if you are using the "normal" DC control stuff here - like DCSSRs or Ren24LV then you want Common Anode. This is because the -DC(GND) is switched on the SSRs and the +DC is common to all the LEDs.

This group buy is now CLOSED! Thank you to everyone for paying rapidly. Everyone got their payment in before the deadline, so all LEDs will be ordered!
I will be placing an order for over 10,000 LEDs! Because of the size of the order it will take a little longer to arrive at everyone's door step. The seller has agreed to prepackage all LEDs in groups of 60 so my turnaround time will be very fast. The seller states it will take 11-12 days for me to receive them. I will have all orders shipped within 36 hour of receiving the LEDs. Most participants should have their LEDs delivered around March 20th.

Got mine yesterday as well - Thanks Todd!
I use 5v for mine and I'm using 100ohm for Green and Blue and 150ohm for Red. I don't have White on mine but I think they have the same Vf as the Green and Blue so they might be 100ohm as well. This gave me 18/19mA current. Be sure to allow for voltage drop from your cabling.
akonkman
03-27-2010, 12:16 PM
I think I'm going with 100 ohm for Green/Blue and 150 for Red also, using a 5V supply. Don't make the mistake I did: I breadboarded one RGB LED to test out what resistor values I am going to use, and I used the pinout that is shown on the ebay listing (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110483571089), but apparently that pinout is wrong, as I had a 100 ohm resistor connected to Red and ended up ruining 2 LEDS in the process. So you might want to start with a higher resistor value for all pins at first to ensure you know which pins are Red, Green, and Blue! (The common anode pin is correct)

Actually... I can't yet as I don't have white on mine yet! However, I recall these are 3.0-3.2Vf so a 100ohm should work for these as well - do a quick bench test to be sure. Note - - a BOM like this will only work if everyone is using 5v - if you are using anything else (like 12v) they'll be different of course...
Also - I'd suggest 1/8W resistors if using 5v. Since maximum voltage drop is ~3v on the resistor (for Red) and at 20mA, this would be .06W - well under the .125W of the resistor rating. If you're using 12v, the maximum drop would be ~10v which would be .2W - way over .125W so you must use 1/4W for that. The resistor pads are on 3.5 centers (I think) so the 1/4W resistors are a very tight fit. That's what I used on mine but it was a real PITA... The 1/8W will fit nice and easy.
If you aren't going to daisy-chain the strips (you SHOULD NOT daisy-chain if fully populated!) you can get away with only one RJ45 per strip. You'll also need to house these in something - they can't be out in the weather.
You can test these w/o a controller btw - just use a REGULATED power source and run the "+" to pins 1,3,5 and 7 and then tie the "-" to pins 2,4,6 or 8. I used an old phone wall wort which used a switching regulator in it for mine - but you can use the supply you are planning to use as well as a test. Keep in mind that the colors go RBGW - not RGBW (unless the LEDs have changed since I got mine) you must account for this when wiring things up or sequencing.

If someone wants to work up a working BOM for the strips I would be willing to run a coop to pupoluate them. I won't be able to test any strips until I am able to get my grubby hands on one of budude's strip controllers.
This would be great, but might be hard because some people are doing strips different ways. But doesn't change that it would be great!

Where did you get the values in order to calculate this? I followed the link to the EBAY site, and the forward voltage for all three colours was listed as the same, as was the current ratings (0.25ma). Now I know better, and realize that the RED is almost always different from the other two, and your values support this. So.. where did you get your starting numbers from? Is there a data sheet, or was this a case of trial experimentation, and recalculation?
The reason I ask? I'm considering running these off of a 12v supply. So was going to recalculate the resistor values required. (best guess at the moment = 460ohm, 360ohm)

This data is from budude last year in a thread. And his reply to me has a little more detail on this. I bought strips last year but didn't have the channels or tubes for them. But I kept on top of the threads and know a little bit from others. This year I bought Ren24LV for them, then changed my mind to add DC SSRs, and may change my mind again to budude's controller.
Anyway back to your questions, budude tested last year and came up with those figures.

I got my values by experimenting on a breadboard first aiming for 20mA and ended up with 18/19mA. I think I recall the info you mentioned and sent an email to the vendor and he responded that the Red was not the same as Green/Blue - guess he never changed the datasheet...

So can I assume your resistor values provided 18/19 ma on all three channels? Thus working backwards to figure out the Vf for each colour?

Correct - I think it was 2v (Red) and 3.1v for (Green/Blue) and I allowed a bit for cabling voltage drop (~.25v or so) as well.

It seems to depend on the actual resistor. I got NTE brand metal-film 1/4W resistors last year and had to bend them as sharp as possible to barely fit so I got 1/8W resistors this time. However - I had already purchased some other 1/4W resistors (150 ohm) when I bought LEDs for my LEDTriks and those fit perfectly fine - - so I guess the answer is - it depends. However, there's nothing wrong with 1/8W when using 5v since it's only 20mA across the resistor and even if the full 5v were across it it would only be 1/10W (.020 x 5 = .100) but of course the LED drops 2-3V so it doesn't even come close to that... If you're using 12v you'll probably need 1/4W for sure...

To clarify - the RGB LEDs go in as per the silk - it's the WHITE LEDs that go in 180deg off... Also - Everything labled "G" is for Blue - everything labled "B" is for Green. At the RJ45 it goes:

2 - Red
4 - Blue
6 - Green

Note - since you are one of those getting the Ren48LSD - I did NOT re-order the colors on the board which means you will either have to swap pins 4 & 6 on your Cat5s to the SuperStrips OR you just reorder them in Vixen if you want them in RGBW order versus RBGW order...
I did not change the order as I already have my existing strips cabled that way :roll: - plus - in case someone wants to use these for other purposes, the channel order goes in the same order as the cable pins (2,4,6,8).

You will need to calculate for them - but it's not too hard. To get in the ball park use 2v as Vf for Red and 3v as Vf for Blue/Green/White. So:
RED: 12v - 2v = 10v across the resistor - if you're shooting for 20mA (normal) through the LED, it would be 10v / .02A = 500 ohm. I think the next common size would be 510 ohm which would give you 19.6 mA.
BLUE/GREEN/WHITE = 12v - 3v - 9v across the resistor - if you're shooting for 20mA (normal) through the LED, it would be 9v / .02A = 450 ohm. The next common size up would be 470 ohm which would give you 19.1 mA.
You do not want to down in value as that may raise the current too high.
If you have a breadboard, you may want to try these values out first. If you do go straight to the strip, mount only one set of resistors and one LED and see how it looks and do some measurements there. If all good, then go at it!
mschell
05-08-2010, 02:03 PM
And remember that you'll need a larger size resistor for 12V. Since the voltage drop is 9V and 10V, times 20mA, you'll need at least a 1/4 watt resistor. (9*.020 = .180 Watts, 10*.020=.200 W) 1/4 watt is .250W, so you should be OK.
Check the size of the resistor you choose, because those positions on the strips are fairly small...

570 ohm? Where do you live? Some places might be nearby and you get stuff fairly quick. I have Jameco right up the peninsula from me - typically not the cheapest but if I order in the morning, the stuff will be at my door by the afternoon of the next day. Digi-Key is in MN, Mouser in TX and Newark is in Chicago (I think?) so the Midwest is covered pretty well!
If you're just experimenting then it doesn't matter but I wouldn't want to mess with 2 resistors together.

I started soldering mine today. I'm using the 5V rail from an ATX power supply to power them.
The PS is putting out over 5.6V and I am getting 23mA of current with the suggested 100/150 ohm resistors. This is with the PS connected to the strip, so there's no voltage loss accounted for.
If you have a PS that is putting out 5.0V, I personally would reevaluate the resistor sizes.
These LEDs are rated for 25mA.

They are rated for 25mA MAX but have a suggested nominal current of 20mA. If you have a decent voltage drop in your cabling, then yes it's fine but if not, I would not run them above 20mA... I don't think you'll see any difference in brightness between the two.

Ah thanks budude, you are the LEDstrip master.
The specs from the auction page simply say 25mA, not maximum (nor nominal). I searched around for other specs and you are right on with the 20mA.

I measured the length of the vias for the resistors and they are ~9mm from outside of the hole to outside of the hole.
I also figured it takes about 3mm (1.5mm per side) of room to bend the leads of the resistor without a lot of hassle.
This leaves ~6mm for the actual body of the resistor.
Looking at Mouser, good choices would be 270-VALUE-RC, a 1/8W 1% metal film resistor with a 3.5mm body width or 299-VALUE-RC, a 1/8W 5% carbon film resistor with a 4.2mm body width.
1/4W are cheaper, but with a 6.8mm body width it's going to be a tight fit, although certainly manageable, the p/n would be 271-VALUE-RC and 291-VALUE-RC, respectively.
Anything bigger than 1/4W really will not fit; not that you need anything bigger than 1/8W, but if you have some laying around..

If you order 600 of them, they just use the vendor's packaging of 200 per bag. I didn't actually count to see if there were 200, but it looked pretty close...of course, I'm only finished with about 10 of the strips so far.

What else is everyone using to protect these strips from the elements? I know frank recommends T8 Florescent protection tubes, but those were a little too flimsy for my taste.
I tried to take 1" schedule 40 PVC, and cut a window in one side and slide in Clear PVC, but turned out to be way too tight.
Ended up ordering clear Schedule 40 PVC then using the standard white end caps, ran a bead of Silicone down the back of each board and placed it in. I like it, but the Clear PVC was +$4.50/foot shipped

If, while turned on, I take the soldering iron to them and heat them up they'll turn on and stay running until I remove power.

I have had a few go out as well - especially the red and I've seen the same thing you have. Sometimes soldering gets them going but usually, it just means they need to be replaced.

If I had not soldered in all the resistors ahead of time thinking the new RGBs were going to be the same, I would not have any issues. Could just reorder the channels to make them 'match' the order of the old strips. As it stands tho, the Red would have a 100 Ohm resistor and the Green would be a 150 Ohm resistor. I was just checking to see if anyone brought some and didn't end up ever building the strips. I have a MFG that is willing to custom make me some but figured I would ping the board first.

I assembled 13 complete strips so far and out of all of them I only had an issue with 1 RED led. So 1 out of 234 RGB leds is not a bad fail rate and most likely it failed because I fried it while soldering it.
FYI another 10 strips in progress and 7 not touched yet. But on the BRIGHT side (couldn't resist the pun), My 550 UV Leds showed up from England!

You gotta show those off! I still have 5 strips leftover with no White LED installed and was thinking of installing UVs on these for my Halloween setup...
Time will tell if your RGBs do well in the weather - when I took my 20 strips down to install white LEDs in them, I replaced all the bad RGBs while I was at it. I even tapped the strips on my bench and gave them a small twist/bend looking for loose solder and made sure everything was 100% before reinstalling them in my eaves. After my Halloween show I noticed a handful more dead ones here and there - argh... Red seem to be the worst and then Green - I don't recall having any Blue go out yet and none of the single color white have gone as of yet either.
