I read a bunch of reviews from reputable sites and bought what they said was the best. Apparently they couldn’t even spring for an Arduino because the pulse widths are seconds long.
It's not the logic that's expensive, it's the solid state relay suitable for high power, high frequency switching
I don’t need MHz switching. A few kHz would be better than just turning it on for 1 second out of 10 for “low power.”
Still can't do it with a cheap SSR or a mechanical relay
By "expensive" we're still only talking a dollar or two. It's not going to spike their cost to the point where it would be prohibitive to them.
