Most people don’t use their floppy drive anymore so you might as well make a car out of it, right? If you short two
sets of pins in the drive connector, the motor will spin freely when 5V is applied. This motor is used to drive the
rear axle. The front wheel is steered using the read/write head’s stepper motor. An NE555 timer is used to pulse the
motor when the steering buttons are pushed. This design is really simple and has a tethered control, but it is a good
starting point if you want to try something else.
Nice project as far as I can tell. I wish the photo didn't look as if it dated from pre-floppy days.--bg
