Hi,
I've got a video showing the stepper controller and the 5 buttons that I wanted in my scope control.
its at

motor jitter is because the clock pulses are not synced with button depresses. will be fixed later. the 5 button functions are
high speed CW slew, high speed CCW slew, micro adj CW, micro adj CCW, tracking.
does'nt incorporate encoders at this stage. something to be added later on.
I wanted an autonomous simple but accurate hand held controller, hence this design.
