Tech Ping!...................
I always have to be careful when reading about electronic innovations on April 1st.
Back in the 1970s I subscribed to Electronics Magazine and they always had an April Fools article in the April issue.
The one I can still remember was about a new Input/Output data protocol for interfacing tractors with harvesting implements for automated control and data collection that was proposed by John Deere engineer George MacDonald.
He called it the Extended Implement Electronic Input Output Interface, or the EIE I/O.
I’m not good at readng schematics. Is one of those squiggles the “And Then A Miracle Happens” box?
Heads up

Interesting. Thanks for posting.
I have no real idea how this works, but I use PC power supply to power an immersible pump in a rain barrel for the garden, and a cheap DC PWM variable speed controller for a 12v fan.
Neighbors Pacifica radiator fans will not run unless connected directly, despite replacing sensors. I suggested using a 35 amp switch and a PWM controller, but it would have to be more substantial than mine.
