In this video we will be having a look at a project created by one of my viewers. He created a remake of my power meter/logger project that comes with tons of improvements. Those include 3 channel measuring, WiFi, RTC support, USB measuring and USB-C compatibility. So how good do I think it is from a scale from 1 to 10? And should you consider building it as well? Let's find out!
