Intensifying it w/o doing something about the IR and visible will
probably melt the device, so you get complicated enough to make it not
interesting to do so.
I do have a question. I have a deuterium source with quite a kick.
Anyone have a guess what a deuterium lamp full spectrum would take to
do an eeprom? I would not put hours on my good source to do routine
erasures, but in a pinch it should be more than enough to do the
erasure. I don't have a programmer to check erase state with right
now to answer the question and am asking more to get a pointer to the
spec as to what it takes to erase than anything else.
My first EPROM eraser was a clothes dryer "ozone lamp" mounted inside
of an empty coffee can. Worked just fine. They used to be present
on many 50s and 60s clothes dryers.
You can still get similar lamps, just google for "germicidal lamp"
Not horribly expensive. Add an inexpensive mechanical timer if you'd
like and you're all set.
