Air date: Aug 24, 2018

Until cryptocurrency replaces money, we have to deal with coins. Instead of just collecting them in a jar, this electronic coin bank lets you know how much you have. The simple part is the count counter module which detects up to 4 coin types. The tricky part is making it battery powered. Thanks to capacitive sensing technology, this coin bank can run off a single charge for months.
