Make: Electronics - Intrusion Alarm (Experiment 15)

Today I finished Experiment 15 of Make: Electronics.

I finally got the hang of soldering and now the alarm is all soldered. Below you can see the pictures when the alarm is ready to be armed (green led on) and armed (red led on). It's connected to a pair of magnetic switches that can be applied to doors or windows.
