If we’re to store 120v and 100Uf of capacitance and put the victim between charge and ground, there would little chance of survival

just looked up for something like that and came up with this.
not sure what a 400kv generator is...

but it looked interesting.

This little fella is pretty deadly. He fits in a flat rate box, but I gotta give him back to the humane society when he reaches 2 lbs.

cute little guy. I wouldn't give him back. I think my big guy would like him. But I am really allergic to cats. My cat used to puff my eyes up and drive my sinus's crazy.

Very cool, looks simple enough to make in a couple hours and uses a double A as a power source

Maybe a hairless version? I just read they stink, and you have to bathe them every week, and they’re expensive too. On second thought, the 2x4 is probably the better option.

If you have one mouse, you probably have 10 (or will, in short order...). I feel your pain. I fought a losing battle with the #%Q$#ers in my previous shop. The best thing you can do is seal the shop so they can't get in or out - which means making it just about air tight. If you can't do that (I couldn't) you'll have to get used to trapping.

After trying all kinds of traps I found that regular Victor snap traps were the most effective. "TomCat" snap traps with the huge plastic paddle catch more hair and air than mice... You need to do your trapping in bursts. Throw out 8-10 traps, all at once, around the shop. Check them daily and remove any that have caught mice. After three or four days, pick them all up. Wait two weeks and repeat. Leaving them out all the time and the mice just learn to avoid them.

Good luck!

My mice were slow learners. Got them all, at least last year. Old fashioned mouse traps, all metal and wood. The traps last practically forever, which may be necessary. I bait them with chunky peanut butter, making sure to jam the nut into the curl of the trigger. They can't lick it out, and try to get it. That's what gets them. I set multiple traps out, but soon converge to the area that catches them. Have to keep at it.

Stored energy in a capacitor is 1/2*C*V*V. C is in farads, and V is in volts. 10 Joules of energy would make for a very bad day. There's been reported cases of 1 J causing human fatality. 50 J will likely kill most humans.

Playing with capacitors is fun, but potentially lethal, so play it safe. Even with small capacitances, charging to high voltage can become very dangerous, due to the squaring of voltage.

High voltage capacitors can have a memory effect where after discharge they seemingly charge up by 10-20%. Depending on the voltage range you are playing with, that stored charge can be lethal. Always store HV caps with a shorting bar, never assume it is discharged! I have a couple 200J caps, they are shorted by thick wire between the terminals.

For a mouse, hmm, maybe 5J? That's probably 10x what's needed.

not double A... just used for the schematic... LION cells 3.7 volts .
