I want to make a rat zapper because they keep getting into the bird feed dish. You can’t shoot them because they are too fast and scatter when you open the door.
I made a grid (12 interleeved fingers) of brass on a piece of wood and connect it up to the outdoor light socket with a breaker. Then I just need to turn on the light from inside to zap them when they are in the dish. But BION, 120 volts doesnt do it. They just “fly” out of the dish and run. And that’s just cruel.
I want to use one of my 16 volt/16 amp transformers in reverse to produce ~900 volts. I am wondering whether I can do this directly (with a breaker), or if I should put a light bulb in series with the transformer input (formarly the output) to limit the current. A 60 watt bulb would pass no more than 0.5 amp (60 watts/120 volts = 0.5 amp) to the transformer and stepped up 7.5 times, this would be no more than about 67 milliamps. I’m wondering if this would be enough current and if the bulb is even necessary.
