Servo design for a tangential tonearm

[Straight Tracker]

Hello All,

I have designed a unique tangential tonearm and I am looking for someone to design a micro controller based servo for it. I cannot afford to pay for that service and am interested in trading mechanical design work (3 D solid modelling) and/or precision milling machine work in return.

Sincerely,

Ralf Dieckmann

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

Members expect tone arms to be in Analog Source section. I feel u will get more responses there.

U can get an idea from PLL circuits.
