DIY multimedia projector

From the very beginning, we decided that we needed at least a high-resolution XGA projector (1024x768 pixels). By the way, most of the proposals on eBay describe projectors with a resolution of VGA (640x480) or SVGA (800x600). Who needs 300, 000 or 480, 000 pixels if you can get almost 800, 000? If you buy a ready-made projector with an XGA resolution, you will have to spend at least $ 1, 500. We built our system for less than $ 300. Add to this the excitement of self-assembly and numerous opportunities to improve picture quality.
