If you want cheap ( but no speed control) use automotive relays.
If someone tells you it's easy, they're wrong! Once you get up into the 10A+ range of current, things get difficult.
I'll post a picture. I somehow lost the schematic, but I'll reconstruct it.I've never been able to talk to somebody who REALLY knows what he's doing as far as MOSFET drives goes. That's probably why I think it's so difficult.The latest problem I have is that I'm using 15 ohm resistors between the MOSFET driver and the MOSFET gates. One of them burned up. It wasn't the first. Is a gate resistor really needed? I'm running the PWM at ~20 kHz, so I imagine that resistor is taking a pretty good load.EDIT: I found the schematic I was working on. It's almost done, but I haven't added the actual component values yet.
