Did you ever consider using an array of RGBW (red, green, blue, white) high LED's? I read somewhere that white LED's don't produce the same spectrum of light as an incandescent bulb, and so some colors may not look as intense. Does the picture look washed out at all?

This a really cool project, and you got a great result. (/member/klindner/)
However, knowing what even a few of the components cost off the top of my head, there is no way this would cost less than buying one for most people. Fresnels aren't cheap, and a lens which covers 7"... done right there. Not hating, just stating.

If I wanted to replicate this project, I would need to know the of the parts you used, like the diameter and focal length of the lenses, the size of the heatsink, and so on. For example, I've never used a "triplet" lens before, so it would be helpful for me to see which one you bought so I don't get the wrong one. If you share part numbers or URLs for the things you used, then a prospective maker wouldn't need to hunt them all down themselves (in effect remaking the project in the process).

Interesting write up but I would like more information. I would assume that the (/member/SkilorL/) graininess is due to the LCD? If so is there a better LCD or other display or any other way to get a sharper picture? Would like to know more information IE: parts & cost per part (Even if you bought it off of ebay), links to said parts etc...

You can use a tablet LCD but the interface with an external video source is going to be tricky, unless you're using the whole tablet and an (/member/omnibot/) external pointing device.
