Step 2 Rescue a part.

You will want to rescue a 5 wire stepper motor from an old 5 1/4 inch drive.  You may have to be gingerly with the cable on some of them. Four wires receive impulses and the other wire is for power (+12 volts). Other stepper motors that have more or less wires will require additional electronics which I do not want to deal with.

Slot power cable adapter is great for using the pc ps to power your projects.

Note
You can see the hole where the stepper motor came out of. The connector bar did not come from the drive. I just did not detach it because I wanted to use it for some experiments.  Some really old drives may also have the uln2803, but you will have to de-solder it from a board.

Or you can order a stepper from the likes of MPJA, Sparkfun, etc.
