We have been using this project for many years but discontinued it because of cost, but thanks for our wonderful component donations we were able to start building this project again.
The original code and design was from Andrew D. Vassallo

ASM CODE (Originality from Andrew D. Vassallo)
Programmed the chip using our new Wellon VP-590 universal programmer firmware version 16, yes version 16! When I got it out of the box this morning it only had version 4 and was bricking my ATMEGA328P's but version 16 solved this. Works with Windows 8 just use the 64 bit Wellon software on the web site.
