Several years ago I wrote some visual basic software to control the NEC VT470 projector at Church over an RS-232 connection. The main problem with this arrangement was that the computer needed to be switched on - which wasn't always the way things were laid out. This little project puts the code onto an Atmel AT-Tiny2313 microcontroller. The neat front panel was printed in reverse on an overhead transparency, then the overhead was turned over and glued to the case in front of white backing paper.
