@janbeta I tried several eBay-finds like this back in the days and they were always crap. My ultimate EPROM mass amnesia device was finally made out of a toolbox, gutted fluorescent desk lamp's electronics and a sterilization lamp tube. It has served me very well for bulk erasing for over 15 years now. Not pretty tho.
New video! I'm taking a look inside my very inexpensive EPROM eraser and I'm making some modifications.

For legal reasons I must state that this chip is in fact blank. I would never do something as illegal and wrong as writing my own ROM chip for hardware I own, that hasn't been manufactured in 30 years, when there's a company (that didn't develop it) which is actively licensing said ROM. #amiga #cloanto #retrocomputing #eprom #grift #cbm #commodore
Got one of these cheap #EPROM erasers from China to go along my T48 programmer.
This is the cheapest, most crappy tech thing I've ever got from China. If you plan to buy one - don't! If you have one, consider no longer using it as is.
This thing needs serious modifications to make it safe. It heavily leaks UV light, the mains cord is as thin as a hair, there is no fuse or any other protection inside. Oh, and that mechanical timer may stop working any time never turning the UV light off. This should cost 5 bucks, not 30. Or better, it should not exist at all.
Having spent money on it already, I'll do what's needed to make it safe. But really, for an EPROM eraser, you should not look for the cheapest option. Otherwise you get this...
Graphically visualizing the erasure of a 16kbit #EPROM with a UV source in 16 seconds!
This time lapse shows all of the bits being flipped from 0 to 1 over about a 24 minute period. The first bit flips at 8 minutes.
What's fascinating to me is the bits "twinkle" as they flip back and forth before settling.
