When it comes to the safety of your family, sometimes you have to put a GPS in their pocket. The Spark Nano 3.0 from Brickhouse Security is a great tool for that.

It’s a relatively simple hardware build in that it is simply an Arduino Nano, GPS module, and e-ink display module wired together, but it provides an interesting exercise in running through the ...
