This fun mod was sent in to Hackaday. A guy found a projector in the trash, got it to work. and while he’s waiting for the LED’s to arrive he tried using a candle as lightsource. And it worked, well to some degree.

One of our readers recently found a ASK Proxima C170 (also sold as the InFocus LP600) in the waste bin, thrown away because it stopped working — He snatched it up and decided to try tinkering with it. A visual inspection quickly found the problem, a 100uF cap had blown!

He replaced the capacitor and got the projector to turn on again without much difficulty. Not wanting to pay a few hundred dollars for a bulb he’s ordered a 5000lm 50W LED array from China to give it new life as an LED projector, because as it turns out it’s a fairly simple hack to trick the projector into thinking it has an official lamp in it. It’s just a matter of shorting a few leads on some of the photo-couplers!

In fact, once this hack is done, you can use any kind of light source you want! So just for kicks he decided to try using a tea light candle. It actually managed to project an image on the wall thanks to the optics of the projector! Functional? Not really, but it’s a cool way to prove a successful hack towards an even cooler end project though!
