It's not only your own safety to consider but anyone who may happen on your device and not know it's dangerous |

Not sure if this Forum should be about what cannot be done, but how can one argue with Simon |

You say your a beginner and don't have a clue how to start. This is a bad recipe for creating something that uses high voltage to cause harm under controlled conditions. At least do some high voltage work on stuff that is not meant to cause harm first to give you a firm footing in HV design and then look at this sort of project. If this is something you can get off the shelf then get it off the shelf, it will have already been tested and you won't be liable for any problems it causes under normal operation. |

I gave up on electronic killers, they only get one or two rats. I made a fairly large wire cage, with mesh too small for rats to escape, with a drop down shutter. Inside I put a thin board, suspended on a hinge one end, and the other supported by a spring. Put grain in it, when enough rats are in it their weight overcomes the spring and the floor drops a few mm. This closes a microswitch and a small accumulator triggers a solenoid and the gate drops. You are left with a cage with several (the most I caught in one go was ten) rats in it. You can then dispose of them. Safe, has a simple electronics element, and won't kill things that you don't want or expect to. A large piece of single sided PCB etched into a form of well spaced tacks, alternate ones to ground and a HV supply works, too, put in a cage to keep out cats and other pets, but if only one rat enters, it gets zapped, and being fairly intelligent the others, err, smell a rat (sorry....) and keep clear. It also zaps birds and other "nice" critters, so is not very selective. For lots of rats the cage traps, rat bait, fenn traps or a good small terrier are alternatives. I am unsure if an electric fence energiser has enough clout to kill a rat, probably not instantly. Possibly worthy of investigation. I have a 6kV 1.5 amp DC supply and a vacuum relay, but I think that's a bit OTT..... ;) |
