I can ALMOST do DLP without the external hv power supply, but it
works better with a variable hv supply. It should be possible to
change the voltage on the internal hv supply - there are adjustment
pots all over the board - but I do not have a schematic, and I'm
reluctant to start adjusting things without knowing what I'm doing.
That said, I might give it a try because it would simplify this
project a lot. I do have a "dead" supply (killed by an errant
experiment) if someone would like to trace the circuit. I also do
have the schematic of the hv supply for a Brother printer, if that
helps any. Any ideas would be welcome!
