Topic: $100 DIY 1024/1280 LCD video projector

[Gutbucket]

Built a video projector Friday out of an old 15" LCD display with a dead backlight, a surplus old high school overhead projector, a computer fan and some foam core board and the neighbors garage wall (screen).  Disassembled the monitor to take the LCD screen element with boards and VGA cable out and placed it on the overhead projector.  12v computer fan to cool it and foam core to crop the image and block some stray light. Pluged in a laptop with a DVD drive and voila! Watched surf & concert movies on a 136" projected image in the back yard all night (largest image that would comfortably fit the wall), giggling occasionally like little girls.

They DIY the whole projector with lenses, box and light source in addition to to the old LCD monitor element.. image is probably brighter than an overhead projector, but we didn't have to build a box or work out the light source or focusing.  Just too easy. Total geek boner.

I guess you'll be surfing the 'hoff bikini thread on this one then?

I love doing this DIY stuff, especially the more mechanical type projects. I can do basic things with electronics unless it requires curcuit calculations or testing equipment more advanced than a multimeter.  I've designed a few circuit boards for motor relays at work, but if it has opamps in it then it's beyond me for now.  I've got a few projects in the back of my head that may urge me past that ignorance someday, but I've got a lot of respect for the guys who really understand and can mod that stuff, such as you Richard. +T
