Bug zapper "tennis racket"
MarkMLl:
Just a brief note to say that I've just ripped a couple of the current crop of these apart (rectangular cross-section handle) in order to put in decent batteries. An 18650 will just about fit, and the board has an 8050SS on it which looks like it's rated for 5V.
They're not quite up to the standard of the last one I did which had a couple of D cells strapped to it. Flies which got that up 'em either took up smoking, or- and this is slightly spooky- headed rapidly for the nearest open window or crack between door and frame.

Johnboy:
That's very interesting about the flies seeming to sense the souped-up racket. If it is really the modification that causes them to flee, I wonder at what threshold their "spider sense" kicks in.
MarkMLl:
It needs to connect, but not enough to cause significant damage. At that point they develop an urgent interest in following an airflow to safety, I find the level of awareness this implies disturbing.
I've just belted one with a well-charged racket, there was a loud crack. The cap does claim 2000V rating...

Those things are fun. I was on a group camping trip about 10 years ago where there were so many flies it was unpleasant to sit still. Somebody found that a nearby store carried those zapper racquets and bought several. Handed them out to the kids that were there and they had a great time running around zapping flies, pretty soon they were virtually gone and we could all enjoy ourselves.

I wish they’d had those when I was a kid, I woulda had a blast with it!
I still do to an extent now. :p
