Motorized bahtinov mask

[bojan]

It is hard (and somewhat dangerous for me, the scope is accessible with help of ladders) to place-replace B-mask in the dark during photo session to check focus..

Idea to do something about it came from here (https://www.youtube.com/watch?v=KrSrh4rIldk).

I decided to use this motor (https://www.jaycar.com.au/dc-geared-motor-with-rubber-wheel/p/YG2900?pos=4&queryId=147e60ea3b153b0b0fd17d3815e 3cc0c&sort=relevance), with additional worm gear reduction, initial design is attached.. I have some plastic gears and worms in my boxes, and bracket will be 3D-printed.

Long time ago I used Delphi4 for some projects involving GUI (focus (https://www.iceinspace.com.au/forum/showthread.php?t=66862&highlight=focus+software)).. maybe I will use it again (or similar freeware.. any suggestions? Lazarus maybe?) for B-mask control (I will need to use 2 relays (https://www.iceinspace.com.au/forum/attachment_browse.php?a=284452) from Relay box discussed here (https://www.iceinspace.com.au/forum/showthread.php?t=195590).

I am looking to do the same. How I motorise it I am not sure. But for controlling I will use Astroberry so the scripts can do this automatically.

I hope to make another mount and control it with Onstep. I am hoping there is a lot of output functionality available for control as well.

Model done, now printing... 3 parts.

Following with interest! Your engineering skills are quite admirable so keen to see how you solve this.
