MPJA.com has a black light bill changer for less than $4 US. Could this be used to erase windowed PIC's?
If not any erasers out there CHEAP?

The answer is "probably not in your lifetime".  The germicidal
lamps specialize in UVC, down around 230 nm.  The bill checkers
use a violet led that's around 350 nm, which is UVA.  not nearly
enough energy to wipe them.  too bad, a cheap UVC LED would
be nice.

The problem with these is they use a tube with a black filter on them so
only the longer wavelength UV is radiated. This is fine for making banknotes
glow, but not high enough energy to get the EPROM's to erase.

Change the tube for one without any phosphor, and build a case around it,
preferably with a safety switch so the UV is not on when the case is open.
