At my church we recently lost two Optoma EP759 DLP projectors. Both had color wheel failures within a few weeks of lamp replacement. So I decided to hack one of them to function without the color wheel by removing the remainder of the glass from the wheel (leaving the wheel assembly since the projector needs to believe it's there and see it spinning in order to function). The result is a much bright projector, with one of the main sources of light loss gone. It's greyscale only, but very bright for a portable projector. It has potential theatrical applications in our church, but I'm posting this to demonstrate what this bad boy does to a lighting gel directly in front of the projector. It burned this hole in the gel within a couple seconds. Yay for high lumen greyscale DLP projection. And re-purposing seemingly broken equipment :)
