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...
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 is
12V 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.
