One time I needed an AVR programmer for a test stand that didn't suck[1] and didn't backfeed the device under test. So I designed one using an AVR. And programmed it with the crappy one. Then I programmed the next one with the first one. Feels good. [1] Atmels cheap USB programmer would lose it's mind if the programming pins aren't all connected[2]. Tech had to reset it manually by unplugging the USB cable. If it happened a couple of times in a row, windows would disable the USB port. [2] Board house liked to put their inspection stamp on top of the programming port pads.
