Servo design for a tangential tonearm

Making it a little easier

Hello All,

I have selected the following components for the above circuit: Hall effect sensors, Digital and analog, Stepping motor and stepping motor driver. Also, the servo could be TTL controlled rather than by micro controller. I would like the circuit to operate on a single 5V supply.

Hopefully this makes it a little easier for someone to be interested.
I know enough about electronics to provide a block diagram to show what I need. And I can do my own prototyping. I used to tape printed circuit boards in the seventies.

Sincerely,

Ralf
