The code creates a serial stream of bits. One byte of this stream represents the PWM-state of 8 outputs at a certain time. I’m not using ‘the PWM’, I’m making my own.

How do you use the pwm to turn on each led if it is a serial circuit? Hi there, can you explain the functionality of the circuit?

If you're planning to glue fibers to the LED segments, you'll need a diffuser in-between, or you'll be picking up the unmixed fundamental colors. If you require increased brightness and several boards, you should have a look at the 'rainbowduino' by Seeedstudio (about 50$). My little controller board (starts at 37.50$) is only good for indoor situations with reduced lighting. If that is all you need, you can get it and another LED doodad <a href="https://shop.spitzenpfeil.org" target="_blank" rel="nofollow">here</a>. Hi,

Do you have any of these available and what is the price? Thanks! Ben Smith I am interested in one of these 8×8 RGB Matrix boards for a fiber optic project I want to build.

I’ve got one of this and one of this left over. Unassembled and no matrix.

Any chance you might still have those pcb:s laying around? I pretty much have the same problem as Nick. :) Excellent work! Any chance you might still have those pcb:s laying around?

The only change I did was add a resistor, a capacitor and a jumper. Also I fixed a small mechanical "discrepancy" between theory and real life object :-) Assuming that KICAD worked as before, it should have produced proper files. Well components, how about your favorite electronics distributor (mouser, digikey to name a few big ones). The mini-switches I used are available at <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=97" rel="nofollow">Sparkfun</a>, if you don't want to go hunting for them. But you could surely find a cheaper source for them. There is some information on my datasheet page. The footprint is metric. It's the third one from the top (LPH). The LED matrix is available at Ledsee.com or Seeedstudio.com. The first source is cheaper. Both are in China and have webshops. All the other parts are easy to get. Just make sure you import the libraries in EEschema (preferences --> libs and dirs) and the netlist/footprint linker CVpcb (preferences --> configuration) Edit: there was something strange in the V3.03 files I had uploaded. I'm fixing that right now. The V3.00 gerber files should be OK, that is the boards do work. The small pin offset is just a nuisance. @andy
