I'd like to use one for visual fine motor focus when I don't want to set up the PC, cables etc. Something like the Moonlite or Skywatcher DC motor focus units, but for those of us with stepper motors already attached.
Avalon were thinking about a re-chargeable one, but I don't think it came to anything: http://www.avalon-instruments.com/products/x-md, plus the 1 Amp max limits the motors it can control.
Thanks for any info. |
How about a 12 volt battery pack, (many options there), with a DC plug on the end, some velcro and plug that into a Moonlite stepper motor focus control box. The one I have, has a 12v input socket for power. Button controls are in, out and there is a variable knob for the speed.
Or DIY
I say that as I'm making a DC motor controller at the moment to control a Meade focuser. Hope to post it here on IIS soon, once it's done. My point is, when doing the research for this build, I found it's very close to doing it with a stepper motor, same hardware. Differences being changes to the code (Arduino stepper control) and slight wiring changes. Cheap from Ebay stuff etc.
So if DIY is an option... That will be my next project.
Cheers,
Damien
