Massive SNIP
The controller circuit:
Here is a site I ran across. It is a run-down on FET H-Bridges for
FD/REV control of a DC motor. It presents a simple circuit, no special
FET driver chips. The down side is that you have to build (included in
article) a small device to provide 24v to operate the FETS.
Haven't tried it, but looks reasonable. Link below....
