Daniel Grießhaber @ hackaday.io has published his build of a USB power meter. His device is based on ATTiny 85 mcu and 0.96″ OLED Display and is able to measure voltage, current and power output from USB port.
Since USB has become more and more a power delivery standard, it would be nice to have a convenient way to measure the power consumption these devices need. Of course there are already power meters out there, but they are just boring or don’t have all the features I like.
