EPROM ERASER This is a nice UV EPROM eraser I bought on Ebay on '07, by aroun USD15, low cost type, so it did not had UV protection, and I modified it to include one. Not a big deal... just the pictures as a reference, since even low levels of UV can be dangerous to eyes and skin. A litlle micro-switch and convenient positioning done the job. I included 2 leds to indicate when the gadget is on or off.

    A half hour inside this  box can erase most of the UV eproms I used up to now...


The EPROM eraser as original one.


Drilling the posts to attach the micro switch and the micro switch in place.

Even a small movement of the drawer can turn off the UV lamp ballast.
