Translucent Leaf-Button Lighting 101

Knievel:

Scooter they are the readily available light-blue ones.
I managed to track down some of the dark blue and they didn't light up as well.
They did match better when they were turned off, but they never will be ;)

Lilwolf there's 2 LED's between the buttons, back to back. I wired those together to simplify things.
The LED's are all daisy-chained in parallel with the proper resistor for 12v supply on each one. Then they connect to a spare 12v(yellow+black)molex connector on the computer power supply. Very simple, no extra power source to worry about and they turn on/off with the computer.

BTW I experimented with 1 LED per button and they looked pretty good but 2 pointing at one another really does the job...3 made no difference.

On the NEON CP there's 2 LED's beneath the trackball as well.


Jakobud:

Hey Kneviel, would you be interested in writing out a tutorial on wiring LED's?  I've forgotten most of what I once knew about resistance and current and stuff, but a lot of people here have no idea where to start for something like this.  Perhaps you could just write a simple tutorial for lighting up a few LED's.  Like tell what values of reistors to use and why to use those and how to wire it all to a power supply.  Is this something you could do?  A lot of people here would benefit from it.

I 2nd that suggestion, if you have time.
I would go ahead and emulate this, but the wiring is over my head.
I wired my entire control panel no problem.

I have 2 coindoor lights with the lights in them (normally sold that way) and I can't get them wired up to a power supply even.
:(

ChadTower:

It's a good design, and I can say I may emulate it myself.

Knievel:

Well guys I'm pretty busy at the moment but I think this tutorial about covers it...

I went the Parallel route, if you're using a 12v supply you'll need a 470 ohm resistor for each LED. For the 12v you just connect the LED leads to the yellow and black wires of an unused Molex connector coming out of you computers power supply.

I would suggest buying the LED's off eBay from a seller who packages them together with the proper resistors. I just did a quick search and this one seems to have good quantities/prices....

If you have a specific question about the process just ask away.
