Your electronics videos AND your website are the absolute BEST I have ever seen on electronics, and I have seen a lot. Thank You sir for your generosity. Minneapolis MN
As always a very interesting video. Do have a video on the non-contact 3 phase 2,300vac identification [A-B-C] [L1-L2-L3] line tester? Most of the testers are rated at about 700 to 1,000vac. Also, there are several 3 phase motor rotation sequence tester. Do you have a circuit video on these devices? 🧐 Thank you.
Great video! i'm building a small model engine, and i'm thinking of how to make the ignition. I guess i have two choices: a steel wheel attached to the crank with a gap tooth, and a Hall sensor biased with a magnet. Or a wheel of any metal, with a small neodymium magnet glued to it. Any opinions? Also, i've noticed that the flywheel of motorcycle engines usually have 2 or 4 large (wide magnets), why do they use such wide magnets? Wouldn't that lead to imprecise timing? thanks
Several issues could be improved. It depends on the RPM. Gluing a magnet to the flywheel at high speed may detach the magnet. The hole magnet idea would be best. Multiple sensors can be used to sense the position of rotation. The gap between the pulses would indicate speed, etc.
It does not look like an SSR to me. It has a set of 2 pins and another set of three pins. Measure the resistance of the three pins to each other. If two are shorted and are open in relation to the third that is a mechanical relay and the other two pins are the coil. I couldn't find a spec sheet either. Let me know.

Thank you @Lewis!

Happy Teacher's Day Sir
Hi LEWIS, Do you know where I can get hookup info for a grayhill 70yy20010 solid state relay? thanx

@@LewisLoflin THANKS
Dear Lewis, I have learnt so much from you MOSFETS videos. Thank you so much, you are an amazing teacher.
