Overhead Projectors

Posts Tagged ‘computer’

I never said this was a how-to video. It would be duplicated effort. Check out http://www.youtube.com/watch?v=b7lWqKHpGuc&NR=1 if you want to learn how to build one yourself. Their project looks to be very similar to what I did.

Cost: under $200. Make an 8 foot screen TV / computer monitor from old computer parts and an Overhead Projector. The projector is higher wattage (brighter) and the screen has more pixels (sharper) than a standard computer projector so overall I’m quite satisfied with the way this project turned out. The higher wattage bulb is bright enough for a clear daytime picture but it also raises your electric bill and puts out a lot of heat. I taped a quiet CPU fan on top to keep the screen cool. It just blows across the top surface of the screen, nothing fancy.

Operating system: Fedora Linux $Free
Computer: Junk AMD 1GHz O/C to 1.4 GHz (upgraded to 2200+) $40. (It came conveniently with a vintage ATI All-In-Wonder R200 TV/video card)
Monitor: Generic LCD (WXGA?) 14″ $20
Projector: Used OHP re-wired $50
Screen: Letter-size paper sheets and lots of scotch tape.

This is an Overhead Projector (remember math class?) and a TFT LCD panel. Simple to make, and best of all, cheap. Total cost for this project including all cabling, LCD, fan, Overhead and the laptop was under $200.
