I'd like to develop an automotive cruise control using a 5.25" floppy stepper motor -- the general idea seems simple enough (particularly since I have no experience building computer hardware
) -- I'm a computer programmer who has also remodeled, rewired, and replumbed my previous house, so I'm comfortable with the overall project idea.
Has anyone already done this?
My general plan is to:
1 determine all the ways to instantly disconnect the device -- brakes, manual switch, etc.
2 build or obtain a clutching device that defaults to a physical disconnect.
3 figure out the interface required to interface with my tachometer signal or a single spark plug impulse (manual transmission, so I definitely don't want a speedometer connection!)
4 write or obtain arduino software to recognize current frequency of tachometer impulses.
5 modify arduino software to drive stepper motor to control throttle.
