Homemade Projector
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 lap. . .

Very cool can you buy those screens with A/V inputs withound moding a laptop screen
overhead projector bulbs often retail for closer to $30. and projector bulbs are more like $250-500but the more important factor here is that real projectors with the expensive bulbs, are much, MUCH brighter than overhead projectors, which allows for better throw and projection area.
my projectors bulb cost like 15 bucks
They actually aren’t that much brighter. In a dark room, you could throw this thing 20 or 30ft away and still get a good picture. I don’t even use this anymore though, I have a LCD TV that is easier and quieter to use.
this is cool if you can make one for under $100, but $200 is a lot of money to spend for something that looks this bad. digital projectors have come down considerably in price and look amazing these days.
Look at the date dude.And read the video desc. Under $200 WITH the laptop.
Epic win =)
i don’t know if this would work, but i’d like to see what would happen if you used a 750w ETC Source 4 as the back light. You’d probably have to use a glass panel to help diffuse the heat.
what overhead are u using please tell i have a 3m 1830 projector and its to dim
3M 9100.
