Use of several robofocus motors from a single control box

[Gerald Sargent]

I currently use two motors to focus imaging and guiding OTA's.
This involves some especial circuitry between to control box
and the individual motor, and a new "focus contol box". The
latter has a motor select switch and push buttons for in/out
movement. The special circuitry uses four FET's per motor
and on my system is housed in a small aluminium bracket with
connectors for each motor and for the robofocu control unit.
Anyone wanting the circuit is welcome, just let me know. I have
no ability to get drawings onto a computer but I am sure someone
will help and it can then be got into email form.

It's always good to get someone elses ideas, please post if you can. If you have a digital camera you could simply photograph your drawings (and equipment) and post on the forum.
