How to solve EMC problems! || The mystery of the buzzing speaker



Thought this might interest some, Great Scott on dodgy power supplies, and a quick visit to the EMC lab.

Funny enough I have that exact same dodgy LED light with the same dodgy power supply, but never actually used it to do anything more than a brief test of the lights. Used another one instead.

Nice.  Simple, superficial, informative.  I don't watch his channel regularly but from the few I've seen, the factuality seems a bit hit or miss.  This one landed pretty well.  (I wonder if maybe it was even reviewed by Wurth not just for marketing value but technical as well?).

Also, TIL they make ferrite anal beads... :-DD

Oh, yes. It's somewhat informative, but clearly advertising for W├╝rth?
