[Alex] put together this handy cheat sheet to make pinout lookups much quicker. It covers the most common chips from the AVR line, ISP headers, and FTDI cables.

Mass production is a wonderful thing. Prices fall, and hobby hackers get cheap gear. The mind then wanders towards what can be done with it. So it’s little wonder that someone like [Aaron Christophel] ...

This circuit is intended to program AVR controllers such as the AT90S1200 via the parallel port. The circuit is extremely simple. IC1 provides buffering for the signals that travel from the parallel ...
