Also, it would not erase PIC12c508'S. You see, they cost much less than a dollar, and this is a BILL checker. It would reject them every time +ADw-Groan+AD4- -- Lawrence ----- Original Message ----- From: +ACI-Alan B.

If not any +AD4- +AD4- erasers out there CHEAP? +AD4- +AD4- The problem with these is they use a tube with a black filter on them so +AD4- only the longer wavelength UV is radiated. This is fine for making banknotes +AD4- glow, but not high enough energy to get the EPROM's to erase. +AD4- +AD4- Change the tube for one without any phosphor, and build a case around it, +AD4- preferably with a safety switch so the UV is not on when the case is open. +AD4- +AD4- -- +AD4- http://www.piclist.com hint: The list server can filter out subtopics +AD4- (like ads or off topics) for you.
