Power MOSFET tutorial

Best short description of how to use
power MOSFETS that I’ve ever found.

Now I know why the power sucking pig of an electomagnet I made from hookup wire and a nail is so hard to drive with a power MOSFET.

Also, shows why sometimes you are better off just buying controller chips that do the job you want than to try to roll the circuitry yourself with discreet components.
