That's a rather serious accusation. What prompts such a statement?

Call me old fashioned, unknowledgable and noob; I am, in fact, all of

Which was always the 'scare' when you saw a 'stickered' EPROM and the

It's like using a refrigerator magnet to try to bulk-erase a disk.
It works great and instantly, IFF you did not want it erased.
If you WANT it to erase, it'll take forever, and never quite finish.

Solar UV radiation w/o intensification has been shown not to erase most
eproms.
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.
device is here:

Also have a mercury source:

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.

But remember, the short-wave UV can harm your eyes fairly quickly.
Catching a brief glimpse of it won't hurt you, but avoid looking at it
any longer than that. Put it in an opaque container. I strongly
recommend installing a switch that turns off the lamp when the container
is opened.
The closer the EPROM window is to the bulb, the faster it will erase.
Experiment to find the necessary duration for the part to verify erased,
then double the time to ensure a good margin. When the bits first read
as erased, the charge of the floating gate is only slightly below the
threshold, while you want it to be completely discharged.
If you're in a hurry, it is also possible to use a Xenon or Krypton
flash tube (provided that it is made from quartz class to not filter out
the shortwave UV) to erase the EPROMs nearly instantaneously. Needless
to say, this is even more potentially harmful to the eyes.

Hi
Actually that isn't exactly true. That frequency of UV don't even get
to your retina. It is mostly stopped in you cornia so you don't even
have to be looking at it. If there is any direct line of sight between
the source and your cornia, it will damge your cornia.
Most surfaces don't relect it well so you don't usually have to worry
about it bouncing off some paper or wood surface. Even
metals are not particularly good reflectors. I wouldn't use prolonged
exposure to a reflected source but it is most likely only a fraction
of what the direct source is.

Awesome stuff. I didn't know you hacked on that sort of stuff.
You should be on the "lasers" list that I run. It's not just lasers,
but other optics and high-energy physics stuff. There are some serious
heavy hitters on that list, including a technical celebrity or two.

Yes, in perhaps a month. The total necessary UV does for a typical
EPROM is about 15 Watt second/cm^2 at 253.7nm, though wavelengths below
400 nm cause erasure. An EPROM eraser provides about 12 mWs/cm^2. At
sea level, exposure to direct sunlight delivers a maximum of about 0.1
mWs/cm^2, so erasing an EPROM will take 120 times longer, or 40 hours,
but that is 40 hours of peak sunlight, so the actual time is much longer.
The reason you need a UV-opaque label on the window of an EPROM to
prevent erasure by room light or sunlight is that erasure is a
continuous process, so the bits will start to get flaky long before the
part is fully erased.
