LP250 LCD Dyi Halogen Hack

This page is kept for history; this hack was made many years ago. 

I haven't written much about this project yet, but it's one of my favorite DIY hacks—turning an LP250 projector into a kid-friendly cinema setup with a simple halogen lamp upgrade.

To save on costs and keep things simple, I decided to swap out the original bulb with a regular OSRAM 50W 12V TITAN halogen lamp. The result? A perfectly functional projector that casts a crisp image on the wall in a fairly dark room. It might not be cutting-edge, but it works brilliantly for our needs.

The projector now throws up an image about 2-2.5 meters diagonally on a white-painted concrete wall. My kid absolutely loves it—especially when Lilo and Stitch are playing, and Lilo is nearly as tall as he is!

The best part? Thanks to a helpful picture I found in a newsgroup (see below for the source), I could modify the projector without fully dismantling it. I just had to remove the front panel (two screws), short-circuit two black wires, and voilà—the projector fired up without a hitch.
