Hello everyone !
I love your project. So I made pcb.
It works perfectly.
if you are interressed : ebay
[MOD-EDIT] It seems there are some issues with this PCB, just keep in mind and maybe ask darkbobby if you want to buy it
In my defense, the printed circuit boards are factory tested, no problem with that. The factory does not build it if it is not functional. i'm not a thief. The 2 problems were the solderer who soldered upside down or overheated the matrix led display by soldering it.
99% of the time, the problem is human ^^
