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. Craig
