I just ordered the connector and pins from Tischer, and a plastic project box and a couple of switches from DigiKey. Need to find some battery terminal aligators. Have everything else.
Looks like in total it will cost $30-$40, depending on how many parts you already have laying around.
I hope to never need it either, but if I do, I'll need it really badly.
Mostly I just wanted to prototype it for others to enjoy. I'll post pics and the complete costed parts list as soon as I have it together.
