projector

The time is 22:17. I am going to build the system described here. It will take about an hour. Here is the untouched, $210 CMV CT-522 LCD screen, powered on for the first time

The mount doesn't swivel all the way down like it probably should. Good thing I don't care.

Slightly-used $80 overhead projector 3M model 1700. 360W bulb.

Projector shining on the wall against a 40W lamp.

Unfortunately, the 15" LCD is quite a bit bigger than the working area of the OHP, so a bunch of it will be wasted.

There's a 'turbo' button on the monitor.

It flips between a few brightnesses.

I cannot find any bad pixels.

case off

the ribbon cable is stuck to the case, but peels off

I stuck the front control panel to the metal cover.

backlight connectors are on the left

diffuser layers on top of the backlight, which is now detached

prototype projector setup with fan

wooden dowels hold the LCD above the warm projector so air can blow through
