Re: Dinghy theft protection

I have set up an alarm system based on the following link.

If anyone is interested, pm me with your email address and I can supply an updated circuit diagram as I seem to remember that there was a small error with the attached diagram and I have an amended diagram on Excel. The circuit is based upon a $6 Radio shack relay

Dinghy Alarm

Most of the solutions I had seen before tell you after the dinghy has gone, This solution tells you that some one is trying to take it because as soon as the wire loop is cut, the alarm goes off. I have loud buzzers and lights attached to the relay.

We have also extended the circuit to allow us to have a “panic” button in the sleeping cabin in case you feel someone is too close at night.
