'2nd hand EPROM eraser needed'

Hi:

I'm getting started with the programming of pics and since many of them
have eproms I will surely need an UV eraser. Does any one of
you have an extra one or one you don't use anymore. If so
please e-mail me with price and S/H costs.

P.D.: I apologize if this is not the right place to post this message.

Thanks,

                        Pedro J.  Barrios

It's very easy to make one. Just buy a 12" fluorescent fitting, and swap
the tube for a UV tube. I don't bother with a timer or a proper box - I
just use the timer on my watch and put a cardboard box over the thing
whilst it is on. With the EPROMs against the tube, they only take about
10 minutes to erase.

I did soething simular with a 6in tube and a $7 flourescent fixture I got
from home depot. It was even battery powered so I can do erasures on
the go.

How ever scavenged the tube from another eraser with a bad ballast. The
real question is: where can you get UV tubes from and how much do they
cost?

I took the innards out of an old 12V fluro light, the kind that you
can use in an automotive environment. I bought a UV tube and
replaced the original tube with it. I placed some black static foam
inside a small wooden drawer and place the chip on this. The tube is
rested directly on the chip and is then powered by a 'Plug Pak'
powersupply.

This seems crude but it only cost me the price of the tube ($15) and
has worked well for over 5 years.

A very helpful little outfit in London (Service Trading Co., 57 Bridgman
Rd., Chiswick, W4 5BB. Tel: 0181 995 1560) stocks them (about #8 UK) and
sells a complete kit (less case) for #15 UK. They also stock the other
UV tubes for exposing PCBs. Not much use to those of you outside the UK,
unfortunately.
