A couple days back we mentioned that Lumenlab had released their top trick plans for building an LCD based projector. Hack-A-Day visitor [Brad O’Connor] sent along his experiences utilizing the Lumenlab plans. like most people, he states that the $20 cost of admission is worth it. The system utilizes a 400Watt metal halide lamp as a light source. A fresnel lens straightens the light before it passes with a consumer LCD panel. A second fresnel lens directs the light to the final focusing lens. You can grab a torrent of the plans here. Brad is currently working on motorizing his 120″ screen.
