If you are interested in direct imaging a photo sensitized board search back
through the posts around Nov of 09 for Volkan. He built a UV laser diode direct
writer that did spectacular images. The 400 nm blue-ray lasers are available on
ebay. He has some images posted under the Files secton of the forum. These UV
lasers are very strong >> 100mW.

I took him a board I had coated in AQ3000 (water based photo resist) to try an
image. Once we got the exposure set the image was amazing crisp.

Volkan also built a drum photo plotter.

Both these project on my list of cool things to build.
