This is a good and fairly efficient flyback driver circuit. All parts can be obtained easily from Radio Shack, including the MOSFET. This circuit uses a 555 timer IC to pulse a 2N2222 with square wave at a frequency that is set by the capacitor and the potentiometers. The 2N2222 then drives the gate of [...]

Here is easy circuit drive a stepper motor with pulse input. Use IC 4013 (IC Cmos) and Mosfet IRF510 drive Motor Stepper.
The circuits below only required a single power source, The maximum power supply voltage can not exceed +20V.
