The traps have been tested and approved to be humane. A stoat is dead before it knows what has happend. Its instant. |

It's sort of too bad the trap is all metal, if you got the right mix of materials used in the base and support structure, you could just wire a sense line on the trigger and the arm and when the sense line goes open, your trap is sprung. |

Dedicated "mute" ICs used to be available which were used in radios, so if you can get one which just presents a logic level change at its output, you are halfway there. If you have to fart around setting levels & stuff with a PIC or whatever, it is a bit more messy, but still do-able. --- End quote --- This is very true. And this gives me an idea. When they go off, they really do go off. Its a very strong spring and it really accelerates very fast. When it hits the base, it really hits. At least for the said 'victim' the end is quick. A peizeo electric transducer would certainly pick up the hit. The problem i have with microswitches ( which would be the easiest way by a long time ) is that these traps are in ugly places, with mud, and rain. A peizo could be sealed up and attached to the side of the box. |
