USBasp - USB ISP/TPI programmer for Atmel AVR microcontrollers based on the design by Thomas Fischl.
Based on Great Scott idea:
Simple (yet powerful :P ) ATTiny programming shield.
Pin 4 connected to LED for simple blink test etc.
Design was enhanced since photo was made. "Yellow LED" is now further from IC,
so ATTiny is easier to grab :)
If you see any mistakes - let me know :)
