Today my EPROM Eraser showed up which I've bought
here (NAWTS).
I've ordered it in France, because I didn't want to wait for the nine-Euro-version from China.

And, of course, I took it apart first before turning it on (which was a good idea anyway).
Overview and a closer look to the electronics.

The wires attached to the UV-lamp did not convice me. I'll replace them and add some shrinking tubes.
But let's have first a look at the backside of this pcb.

Ugly soldering and a non-soldered joint.

New PTFE-wires (the brown ones) and some aluminium foil taped at the lid of the case. Added also some black conducting foam at the bottom of the drawer.

I've tested it with some 27C1001 EPROMs and it is doing its job. That's all I wanted. But I'm convinced, it will for sure not meet the VDE safety standards or the CE standards (EMI).
Thanks for watching.
