I want to add a motor to my webcam to be able to turn it remotely and I want to do this out of spare computer parts, if possible.
I've obtained a 4 phase unipolar stepper motor from an old floppy drive, which's specs go like...
kp39hm2-025 12V Unipolar 4 phase 1.8 degree stepper from Japan servo Red = Common Bl = Phase A Ye = Phase B Br = Phase C Or = Phase D
I was thinking of hooking it up to a parallel port and then controlling it programatically (sending the voltage to the wires is something I would know how to do once within the computer).
Now I know the parallel port provides me only 5V and that the motor is12V but I suppose even an underpowered motor would still turn (I've run 24V installation fans in my computers on 12V and they worked just fine).
Now I've found a post from this newsgroup saying:
...Steppers are produced in two kinds: one is unipolar 4 phase - it has 5 wires, 4 coils with one common connector. common you hook to +5V and switch the ground between the four others...
I realize the Parallel port would in effect have it the other way around (one ground and voltage on the wires).
Would this ever work?
Probably not, so which components would I need to get myself to get this finnished anyway as cheap as possible?
Thanks in advance.
