Don't you have to reverse the yoke connections also? I like the picture

the bright wall lights on - not likely!

Depends on whether you want front or rear projection, either way it's a
silly idea, there's much more modern ways to hack together mediocre
projection TV's these days, as well as a plentiful supply of old real
projection TV's, I've gotten 4 or 5 of them for free over the last few
years, and most required a lot less work to fix up than building something
from scratch would take.
