4-transistor H-bridge:  an interesting 4-transistor H-bridge variant; this is cheap and easy to build, and best of all is "smokeless" (i.e., no combination of inputs can cause  bridge to self-destruct).   (added 7/06)

6-transistor H-bridge:  This is  six transistor "Tilden style" H-bridge; while not as old as  original "basic H-bridge," this goes "way back," and is  basis for many BEAM driver circuits (added 7/06)

Full-featured Dual H-bridge:  I had always assumed that dynamic braking would be most effective at higher speeds. However, actual tests using a Faulhaber (micro mo) gearmotor showed that the brake would hold a motor almost stationary. These gearmotors are so well made that I can turn the 4 mm diameter shaft with light finger pressure. For the tests I had mounted a 90 mm diameter wheel, which gave me tremendous mechanical advantage. I found with the wheel mounted that I could barely turn the motor against the brake.    (added 7/06)

Motor Control Scheme Yields Four Positions with Two Outputs:  02/07)/02 EDN Design Ideas  /  (added 7/06)  Figure 1 showshow to position a mechanical device into four discrete positions but with only two free outputs and one free input from the control system. The position depends on a set of cams and four corresponding limit switches. The 24V-dc motor comes with a worm gear. Darlington transistors Q3 to Q6 and resistors R7 to R12 form an H-bridge that drives the dc motor, M. ...

Reversing H-bridge:  This H-bridge variant was one of the first in which the reversing circuitry is built into the driver, rather than (as is more-commonly done) into the control circuitry upstream of the driver. This is a handy circuit, though, for 2-motor walkers -as all that is required to reverse one is to reverse the phasing of one of the motors.   (added 7/06)
