Continuing the series of building your own lab equipment, this video shows you how to build a power meter using a rather nicely made module from Peacefair. The result is a useful meter that is similar in capability to the well-known HOPI frequently used in BigCliveDotCom's Youtube channel but significantly cheaper.
Please only attempt building this if you are familiar with mains voltage safety precautions and regulations
