Hopefully this book and this chapter have inspired you to create your own high-tech alarm system.
I am sure that in the future, others will take what I have started here and build on it. At least I hope so.
In the meantime, stay safe; have fun building a home security system with BeagleBone! The following are the links to the CAD software that has been used here. It is a freeware, and you will need ExpressPCB to read the schematic and PCB files.
