.. my personal plan is to interface a homebrew set of switches with an Arduino plugged into an AUX port to provide independent means of controlling focus.
I'd love to hear how this pans out. It's something I'd like to set up. Do you have any instructions on how to do it at this time?
Still just the 6se here, but I did get a Celestron Focus Motor for it. After using the motor for several nights, I decided it was inferior to just turning the focus knob by hand and/or using a clothespin "extender" on the knob. So the motor got returned and the cash used for other stuff.
But.. while I had the motor here, I did create a prototype hand-controller for it. Just two buttons on the prototype, and it works fine. The hardware is simply a very cheap Arduino Pro Mini (no USB!!) board, and two momentary contact push buttons. It is wired/mounted onto a basic breadboard, and plugs into any available AUX port (or a splitter off of an AUX port).
The Arduino code for this is attached, using D8,D9 pins for the buttons, with the other side of them grounded through a couple of 10K-ohm resistors. One can easily tweak the code to adjust the ramping of the focus speed and other parameters if desired.
