For anyone who is intimidated by the microcontroller board or just
not in a mood to build one, I believe I can simplify it quite a bit.
You can probably even do without it by using the original sensors to
read slots in the carrier, but as a better and easier compromise I
think you can use a simple 8 pin micro with minimal other components
(a diode and a bypass cap) to control the printer. When I get a few
minutes I'll give it a try.

Assuming this works, I'd like to offer a little board with the mcu
already programmed to anyone who would like to give DLP a try. The
cost will be minimal, should be under $5 USD. I only ask that you
refrain from asking for one till you have purchased a printer and are
serious about the project.
