Question:
I'd like to make these out of an auto coil, some sort of flasher
relay to make the coil work, battery powered so I can
put these in the grain truck, & other outbuildings
where the mice move in
over the winter and sometimes damage wires ect.
Made totally out of junk yard parts if possible...
If you want a sure kill, instead of a pissed-off mouse, use the same
arrangement of flasher/transformer, but use a small neon sign transformer.
Answer:
I used the vibrator out of an old tube car radio to "activate" a 12
volt coil(sans resistor) to electrify the leading edge of my car hood
when I was in trade school. Got wind that some guys were planning on
"fixing" my car during class, so I rigged an "alarm" with a jam switch
to sense hood opening, which energized a locking relay to activate a
hidden horn and the "juicer" which was connected to a strip of foil
tape, laid on a strip of mylar tape across the bottom of the leeding
edge of the hood.
Lift the hood half an inch or so, and the horn blows, and the guys
hair stands on end. Slam the hood, and the horn keeps going. Lift the
hood to pull the wire off the horn, and it gets you again. If you
manage to get the hood open, you can't find the wires OR the horn.
I found out how well it worked when I went to check the oil with it
armed one day a few months later!!
