Don't leave that light where you can look into the light (It'll hurt
your eyes.  Permanently)  Usually, you want an interlock (safety switch)
in there so the case has to be closed or the light won't come on.

 (I think this sort of UV causes cataracts or some such BAD health
consequence - Just don't find out the hard way, look it up instead!)

 There's a little tiny "Counterfeit detector" at MPJA or Hosfelt, that
is smaller than pocket sized, runs off 2 AA batteries, wonder if it
could be changed into a single-EPRom eraser for field use?  <G>

 If you can find the tube to fit!  Original with "Woods glass" filter
is rather small, two electrodes, no filaments.

Hi,

1,     Could a UV-C tube be used to develop photo resist circuit boards???
2,     An easy and cheap source of UV-C tubes could be your local Fish Pond
/ Aquarium stockist, UV-C tubes are used in water sterilisation units... I
picked up an 8w UV-C tube for £2, ($3 ???)

Cheers,

Chris

Hi Jay,

Normal EPROM erasure does not erase PIC's properly. I had an old UV tube
bought from Kontron Electronics about 10 yrs back. This tube erases the
PIC's perfectly. My customers have problems erasing windowed PIC's with
normal UV lamps.

Thanks
