Hey guys, this is my first attempt at a saber with a sound card, so I am a little unsure of myself. I'm really hoping that this diagram is correct, and if it is not, please let me know what I can do to fix it.

Parts included in this build are as follows:

LED: http://www.thecustomsabershop.com/Custom-Tri-Cree-LED-P1035.aspx
(royal blue, royal blue, white)

Switch: http://www.thecustomsabershop.com/12mm-Anti-Vandal-Momentary-Blue-Ring-Switch-P925.aspx

Charging Port: http://www.thecustomsabershop.com/Switchcraft-21mm-Power-Jack-P822.aspx

Sound: http://www.thecustomsabershop.com/Nano-Biscotte-Sound-Module-V2-P806.aspx

Battery: http://www.thecustomsabershop.com/Panasonic-Protected-18650-37V-3400mAh-P855.aspx

Resistors: http://www.thecustomsabershop.com/82ohm-14w-resistor-P23.aspx
http://www.thecustomsabershop.com/27ohm-10w-resistor-P14.aspx
http://www.thecustomsabershop.com/2ohm-1w-resistor-P946.aspx

If there are any questions or concerns, please let me know! I've made notes in the attached diagram, so I hope they help. Thanks so much for your help!

Welcome to the Forums.

The diagram looks good. You're only going to be using one blue die?

Hey, thank you for your input. I'm glad I have the right idea about this, because I was second guessing myself a lot. In reference to the dies, I was going to wire them together in parallel at the face of the led and then use only two wires to get them both hooked up. Is it better to just use 4 wires for the two blue dies and then solder them into a positive and negative wire?

It's better to use the 4 wires (you can make the connections farther down, but before the board), and a proper resistor for EACH die.

Ok, I'll have to change my design to one where I use 2 sets of positive and negative wires for the blue dies.

If my math is correct, I'll need 0.29 ohms and 0.29 watts for each die (3.7-3.41)/1A = 0.29 and then 0.29 x (1A)^2.

This resistor meets those requirements:

But before I order it, I want to make sure that I need 2, correct? One for each positive blue die wire?

That is correct.

Resistors cost pennies. Always grab more than you need, you can put them in your spares box for the next one ;)

If you want to get fancy, you can wire it in three. Example, if you wire the resistors to each die on the positive side, you could combine the negatives in parallel at the LEDs and only have one negative wire leaving the module. Just keep an eye out for short circuits.

Yeah, you're definitely right on that; Why not just order a few? Especially since there is the possibility of error. I'd rather have too many than not enough. Thanks for that suggestion, I'll order some extras.

How prone to short circuiting would that system be? Is it just dependent on the soldering ability of the individual?

Just keep your joints clean. This is how I wire my tri LEDs but you don't need to do it. Whatever you're comfortable with.

Alright, I think I may actually do it this way then. If I'm not mistaken, it would just be the same as my orginal design, but I would not wire the positives in parallel at the LEDs? Just wire them together after the resistors?

Just for example, if you were running all 3 dice 11771


Maybe it's just me, but your image is a little small for me to see what's going on. But FJK said it's good and there should be very little change, just 1 wire bridging across the face of the star instead of going down through the heat sink.

Liiiiiike this, methinks. 11772

Bleh. My little diagram got shrunk down, too. Hopefully you can still see it.

Yeah, I'm really not sure why my image got shrunk down so much. I made it ridiculously large so that people could read it, but that obviously didn't work. I've tried reuploading a few times as an even larger file but no dice. The diagram you posted was pretty close to what I had, so I think I understand the concepts, which is step 1. I just need to wait for the soundcard and speaker holder to come back into stock :|.

We limit the size of the images posted here on the forum. Normally, you post your pic to a (photobucket or similar) and then post a link, and people can blow it up from there. ;)

Well, now I feel stupid lol. Thanks for that, hopefully *this* link will be legible for all. Now I know why so many people looked at the thread and opted not to comment :p.

So this is the original picture I linked. Assuming I follow the advice given to me, it's the same except I would link the positives off of the LEDs and have resistors for each blue die.

Yeah, I'd noticed that it happens, but for some reason the first photo I put in that comment ended up larger than the second. I guess cause file is larger? I guess I hadn't considered file size before, just image size... Either way, normally I post with my photobucket or just imgur.
