Stepper driver circuit for DOB Equatorial Platform
I have recently constructed an equatorial platform for my 8" DOB.
I have used a thread drive with a 3:1 step down belt an pulley that will be driven by a single 6v, 0.6A or a 12v, 0.4A, 2phase stepper motor.
Can anyone point me to a suitable DIY driver circuit with a variable freq pulse input (555?)
I know I should just go out and buy a complete system, but I still enjoy building the bits myself!
