Portable Password Generator

Built from a modified AVR development board manufactured by Olimex, Pass Key is a sweet little 5V โ€œcandy barโ€ style computer that can generate 16-digit alphanumeric passwords as fast as you can press a button.The original AVR-MT dev board requires 10-14V, but with a little circuitry magic, this power demand can be sliced to a scant 5V without losing any of the display, buzzer, LED, button or computational capabilities of the original dev board.
