Here is a list of the hardware I used: Stop laughing at my bracket Graham – it was a fence post bracket before I bent it into a Z shape and fixed to my ST80 focuser. It could all be smaller if I could: We have placed cookies on your device to help make this website better. You can adjust your cookie settings , otherwise we’ll assume you’re okay to continue.

Ok so far so good – next I tried driving the focuser when attached to a SW ST80 using a direct shaft coupler – knock me down with a feather it works.

I started with the code from the above website and made the following changes: We have placed cookies on your device to help make this website better. Here is a list of the hardware I used: If you could do fous idiots guide for getting an Arduino talking to Ascom it would be greatly appreciated.

I’ll be adding documentation to the wiki over the next few weeks including parts list, schematic plus anything else I think is relevant.

If you want to use different pins on the nano you can simply change the pins defined in the sketch. When I went to look at it again some of the annotations pin numbers, signal names etc had disappeared. Important Information By using this site, you agree to our Terms of Use.

This can be used to track when you might need to refocus as the temperature changes. Posted June 16, Sign in Already have an account?

Ill be adding full details of my Arduino on the sourceforge wiki including circuit and parts as soon as I can. I started by cutting a cardboard template then used that to cut out the cork mats.

Removed the dependency on the AccelStepper library – I didn’t feel I asclm this capability for my geared Robofocus stepper motor. For anyone chomping at the bit, soldering iron in hand here is a sketch to show how to connect the stepper motor control board to the nano. I did join the yahoo group but couldn’t figure their focuser out.

Focud shows the cutout section that slides over the dovetail bar on the ota.

Ive used Subversion for source code control as its what im most familiar with. It could all be smaller if I could: The only drawback so far is that I haven’t found an adhesive that sticks them reliably, so doy needs to be added by mechanical attachment: I used the TB shield and one of these http: I haven’t tried building it with any of the free ‘express’ versions of VS. There’s an SGL Focusers group on yahoo nothing to do with this forum that have the details on how to do this along with the ascom drivers and some software to control the motor.
