I posted a note earlier about a UV eraser setup of mine which is crude but works ok for me. I should have thought about a beginner doing this sort of thing and would just like to make mention that these UV lights are dangerous. They can damage your eyes very easily even though they just seem to emit a pale blue color. It is the UV light that you cannot see that is dangerous. I would suggest to anyone making a UV eraser to ensure that the enclosure is light proof and that access to unwary people is denied. Tony Just when I thought I knew it all, I learned that I didn't.
