eBay-special UV LED insect zapper
Added 2022-12-28 08:57:43 +0000 UTCWell I say "UV" but more sort of near-UV and not very high output. But I suppose an insect might wander in accidentally. The circuitry is pretty much what I expected for this unit, with a fairly spicy high voltage section (about 1.2kV).
I'm almost tempted to buy the fluorescent tube based version to see how they mounted the tubes to allow changing them safely, given that there's no bleed resistor on the high voltage side. (And the units switch is on the neutral.)

One of the commercial ones bit me and tore my rotator cuff muscles. I was a newly qualified biologist with a pest control company, (note biologist not technician) . Visited a site to collect the insects zapped by the systems. Now I'd been taught to turn off and unplug the zapper and they were safe. Not the very old models. I was on tip toe, went to wipe a moth off of the grid, and zap. A witness said they thought my left elbow tried to connect with my right shoulder blade. Ended my pest control career. Went back to my hobby of pyrotechnics... much safer
