Car Alarm

This summer an opportunistic small time thief has been roaming our neighborhood stealing ipods from unlocked cars.  To discourage them messing with our vehicles, I built this circuit and installed it in my wife's car.  We use a rechargable 9V battery and recharge/replace it about every two days.  This project was fast to develop and satisfying to see in action.

Build #2 with battery inside

  1. Woah this looks so badass. Your wife married the right man. I take it you are an engineer because skills like these always come in handy.
