Hi, I have made a H-Bridge with zener diodes for 1 DC motor, you can make 2 though. Steps: 1. Get a motor and a battery. 2. Get 2 zener diodes and a CMOS not gate 3. Connect a terminal to one pin of the motor 4. Connect that terminal to a zener diode. 5. At the other side of the zener diode put a 10M resistor. 6. Then add the input of a not gate to the end of the 10M resistor. 7. Connect the output of a not gate to the other pin of the motor. 8. Connect another terminal to the zener diode, resistor and not gate like steps 1 to 7 but reverse the pins on the motor so that if one pin is high the other is pulled low.

This has not been tested but I think it will work. Bye, Andrew
