Kenneth takes apart a few old “tube” radio receivers and finds 8 Henry inductors inside, which is several orders of magnitude more then regular inductors we’re accustom to. He proceeds to hook it up to a 10 uF capacitor, and tests the ringing frequency of this LC circuit.
This LC pair resonates at 12Hz, which is crazy. Usually, getting an LC circuit to even resonate as low as audio frequencies is challenging, but here we’ve got one which resonates at infrasonic frequencies, and with plenty of arcie-sparkie to go with it.
Moral: Always dig through e-waste piles, and make sure you always have a friend with a pickup truck.
