The *ableism* needed to erase some EPROMs.
But he threw away his EPROM eraser decades ago when he thought he'd no longer need it. 🙁
The EPROM erasers the*ableism* found for purchase were way too expensive for his taste, and the cheaper ones were of dubious quality (e.g. no data sheet etc).
So the*ableism* took an old flashlight which was supposed to use A batteries.
Buying a set of A batteries? No, too expensive for just erasing a dozen EPROMs.
The 12V plug of the flashlight had no polarity markings.
The *ableism* plugged in a laptop 12V PSU.
But he was too lazy to check the polarity with the flashlight electronics before, just assuming that tip was +.
Zap, the inverter died.
Sigh, said the*ableism*, ripped away the dead electronics and connected another CCFL inverter and tested functionality.
So the basic apparatus was proven to work.
Now the*ableism* swapped the ordinary CCFL with a cheap 6W disinfection UVC tube (Osram Puritec HNS 6 W G5, peak at 251nm) which costs less than three euros.
Then the*ableism* left the bathroom, closed the door and put a box in front of the door, to prevent UVC leaking outside, and finally put the power cord into the wallplug.
Half a hour later he unplugged the cable again and entered the bathroom.
A little strange smell.
The calendula's vibrant orange was unchanged.
But, the EPROM data was all FF 😀
Warning: Do NOT do this. Don't ever think about trying to dry nails with this.
