Jameco Electronics carries something they call "Photo Etch Light Bulb Set".
This consists of a 3400K white light bulb and a 4800K UV bulb. The UV bulb

power output, and I've never used it. However, it only costs US $16.95 for
the set (US$ 14.95 each for 10 or more.) Is anyone tempted to give it a go?
(Part Number is Jameco 70471, and Jameco is at 1800-831-4242 or
+415-592-8097. They are in the Pacific time zone).
I have no affiliation with anyone who sells this product.

manufacturers make a transparency at the size of the board, then expose a

light disappears. They then dunk the board in etchant, which removes copper
from the board. This gives rise to, effectively, a contact print made out of
copper. I have been thinking about experimenting with
artistic uses of this process for a while. Has anyone ever done anything with
