PCB rulers usually have measurements that come in handy for a proper circuit board layout. Prolific inventor and electronics tinkerer Bradley Slattery wanted to make a different kind of PCB ruler, so he came up with the DigiRule, a 6″ ruler that demonstrates the basics of electronic engineering.

The DigiRule gives you a quick rundown – or a way to test your knowledge of – logic gates and flip flops. It also has a four bit counter, as well as on truth tables and component measurements on the other side.
