Stolen Bike - Radio Alarm Bike Lock


My bike got stolen. It happened sometime between 10:30pm last night and 11:00 am this morning. I filed an incident report with Campus Security, but that bike is gone. I should have used a better lock. A pair of bolt cutters could have gone through that lock in a matter of minutes, if not seconds.

The thief might have won the battle, but he won’t necessarily win the war.

I want to build a Radio Alarm Bike lock and lock up a decoy bike. This is a simple device that could be built using a cheap-o cable bike lock, a radioshack plastic enclosure box, and an FM broadcast circuit. When the bike lock is cut, it would activate the weak FM distress signal. I would have a radio tuned to this FM frequency in my room and amplified. I could then go out and beat the @#$% out of the thief with a large blunt object. Or, this could activate a security camera, call security, etc.

Unfortunately, I have no funds for this project. It would probably cost me $50. Any donors or interested parties?

I feel your pain. My (locked) bike was stolen the second week of classes here at USC. I like the idea of the lock alarm, but I really like this better: http://www.onguardlock.com/beastchain.html

They’re supposed to be damn near indestructible without the use of power tools. Sure they weigh a ton, but I’m not dealing with this again.
