This really needs little explanation. I basically have some IC sockets with extra long legs (I think maybe they're for wirewrap?). I've put these on small pieces of protoboard with AVR ISP programming headers and the necessary connections to allow me to program the AVR chip whilst in-situ on a breadboard. Very useful for prototyping
You'll notice the jumper on the Atmega board, this allows you to tie VCC and AVCC together, or separate them depending on your needs.
