As well as an Ascom driver there is a stand alone Windows program to control the focuser should some software not have inbuilt Ascom support. Posted March 6, If you could do an idiots guide for getting an Arduino talking to Ascom it would be greatly appreciated. If you dont want to solder directly to the nano pins you may need some 0. This looks like a great project, I’ll certainly have a go. It could all be smaller if I could: Or sign in with one of these services.

This is what needs to go in the box and I also need a switch on the 2 bare wires at some stage.

I had a go at making a remote focuser to use with my MAK a while back http: It also needed a better way of attaching to the scope tube as I was using an old belt to keep it in place which wasn’t always reliable.

For anyone chomping at the bit, soldering iron in hand here ascon a sketch to show how to connect the stepper motor control board to the nano. I started with the code from the above website and made the following changes: Sign In Sign Up.

If you dont want to solder directly to the nano pins you djy need some 0. Looks good Are you planning to release the source code? The VS solution contains 3 projects: There are also some links to videos that show you how to create a driver.

These come in nice convenient ascoom sheets of various thicknesses and are easily workable with hand tools and can also be heated, if you’re careful, and molded into rough-ish shapes.

Note about wiring the stepper motor – the stepper I am using is a bipolar stepper.

This was built using Visual Studio and you will need the Ascom platform 6. Arduino-based Motor Focuser Controller. We have placed cookies on your device to help make this website better. The biggest issue I have had is how to fix the focuser to the ota.

Still need to test long distant USB support for the focuser but I can see no reason why that should be a problem as fiy Canon d works with BYEOS at 20m with Active cable and powered hub – famous last words!!! There’s a ‘humbug’ skin too.

I ran the four ascok from these two motor ports to the pins of a female DB9 connector. I added support for the TMP36 so I could have a temperature reading from the focuser. Or sign in with one of these services.



The best place to asfom is the Ascom website. I needed a way to fix the device that was secure and simple. Next job is get a decent schematic. This will work with the sketch I have posted on the sourceforge site. By using this site, you agree to our Terms of Use.

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. Important Information We have placed cookies on your device to help make this website better.

At the time It was a purely manual device with a 5-way switch to set the direction and speed with a rotary encoder to do fine adjustments. Something like this hardware wise http: Sign in with Twitter. I plan to document the driver, sketch and circuit diagram in due course.

I’m going to look at making a smaller more portable version for my as well, something that is removable for a start.
