znanev built a free RGB color changer PCB. This was the ‘first’ free PCB. It was originally a DIY Life project. Someone had a bunch of the boards made (a TON!) and mailed us a brick of them. They were free PCB filler boards many times during our first year.
If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you another coupon code for the free PCB drawer.
