Otii Review: Super Low Electrical Energy Meter || DIY or Buy || Is measuring µA/nA possible the DIY way?

January 25, 2021

It’s time again for one of Great Scott’s famous “DIY or Buy” episodes. This time with our Otii Arc playing the leading role. Since Otii can measure µA/nA and therefore calculate the used energy of a low power device, Great Scott tries to create is own low energy meter.

Well, we probably would be lying if we said that the result was surprising but see for yourself below and check out how a Teensy microcontroller and an Op-Amp circuit were performing compared to Otii Arc!
