Not sure if HN knows about Mehdi Sadaghdar's (aka ElectroBOOM's) YouTube channel, which is somewhat similar - but takes a more lighthearted view on electronics. E.g. Compare Big Clive's mention of a full bridge rectifier in the video vs Mehdi's YouTube video of the same thing :) [VIDEO]

The linked video of how bridge rectifier works is enlightening, funny and terrifying. Makes me glad I'm a software developer and not an electrical engineer so I'm in no danger of killing myself if I miscalculate. [VIDEO]

> The 60-Hertz AC (alternating current) from the wall oscillates 60 times a second, but the power supply needs steady DC (direct current) that flows in one direction. The full-bridge rectifier [1] below converts the AC to DC. [1] [VIDEO] I just knew which video is linked without clicking. ElectroBOOM is a treasure.
