I’m curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?
It’s all Science Magic to me. I am continuously thrilled that the world is filled with people who are much smarter and more curious than I am.
I’ll sleep a little better knowing the quiet strip flickering under my aquarium isn’t a ticking time-bomb though.
