<The problem you are going to have to beat is how to get rid of the heat <from your projection source. Any light bright enough to make a decent <projection display is going to throw off a lot of heat. You will have to <block or remove the IR from hitting the LCD display or it will quit <working. They don't like temperature extremes. Greetings. I recently made curing unit for a dentist. It uses 4 300Watt halogen lamps and 4 IR filters. The lamps were $20 each and the filters $40. The filter looks like ordinary thick, bluish-tint glass that just _loves_ to shatter :-( Heat should not be the problem. (I can get a 200Watt 12V lamp) -- _______________________________________________________________________________ "The Force will be with you, always."
