Common grey mouse? -- the same thing happens to you average grey-haired
human when 10 kV "activates" large muscle groups. HV like you're talking
about can kill people - please be responsible.

Aw.... Phooey! Didja think I was going to make a 10KV floor mat for the
front door of my house?

It's a rat trap; enclosed. The user (human) doesn't touch the HV circuitry.
The mouse does.

That's sorta-kinda the purpose of a rat trap, no? Kill the mouse, preserve
the human?

(please think responsibly)

France makes oil ignition transformers, and neon transformers which
are electrically quite similar. Given the 9KV rating, it's probably
neon or possibly aircleaner. They're not like auto ignition coils
that produce low-energy sparks. They're more constant-current devices
with high dynamic Z, so once a spark establishes a path it will become
an arc even if the pathlength is significantly extended. e.g.,
Jacob's ladder.

Once an arc starts, as by a mouse, it may not go out even when the
mouse has become char. There's enough power there to create
significant heat. Hence --- fire hazard.

I once made a mosquito zapper from an oil ignition transformer,
hardware cloth grids and an F15T8BLB UV tube. I don't know what got
into it , but it melted clear down. The tube was reduced to a gob of
glass. Fortunately, it was on a pole in the back yard.

OK, so now we're talking rodent-fueled space heater!
Cheap shop heat!

I suppose it would make a difference if it were male or female...and
would it set the Watchtowers on fire?

You know, this does actually sound practically useful.

Seems like it might be a good idea to provide a way to have it turn
back off after a few seconds. I don't think I would enjoy the smell
of burning rat.

Maybe the primary should be in series with an appropriate light bulb.
Obviously a good mechanical design would be needed to keep the
electrodes clear.

I actually built one of these (or I wouldn't have known about the mice not
using the ramp when it's on). However, it was an "observed" machine. I had
so many mice and rats in my goat barn that they'd come out even if you were
working there.

So, I set the thing up on a light circuit (with wall switch), loaded the
bait tray with sweet-feed, got a can of beer, sat by the switch, and just
watched.

The tip-tray actually was the switch... no mechanical parts, per-se. It
would just fall down against one of the secondary terminals. 10KV doesn't
jump very far in dry air, so (IIRC) my switch gap was only about 1/4".

When thumping noises, zzzzaaaaapppp!s, and smoke emerged from the tunnel, I
just flicked off the light switch and killed the power. One mouse launched
out the end of the tunnel like a bullet -- stone, cold dead, but at very
high speed! G
