Make a GPS tracked bike lock that’s triggered when your bike is stolen with stbennett’s tutorial. via instructables
Having just purchased a half decent bicycle, and living in a city with a bike theft rate almost as high as New York, I wanted to have some peace of mind that if a their with an angle grinder were to cut through my U-lock I could still catch them.
My main design constraints were as follows:
The device has to be Arduino based so that if I run into trouble I can easily search the forums for help
Whatever I make has to be able to fit into a small bag that goes under my seat
The battery must last for a very long time, at least a few weeks. I don’t want to have to plan my bike rides around my lock being charged or not.
This project is pretty cheap, especially if you compare it to the cost of replacing your stolen bike! I’ve outlined the cost of all the components used in my design below. I was able to use some old parts I had lying around and hopefully you will too. If I had bought everything needed brand new this would have cost about $225.
