Great work ! Great! I’m also interested in the remote control electronics. I am looking at how I can further automate my LHiResIII for remote control. Especially the focus of the internal doublet and also a control to change the grating position so I can also set a different wave range. so 2 motors should be implemented. I have already seen some examples in the field of mechanics. I would also like to do the controls with an Arduino, but my software skills are rather poor. So all tips, possibly links to website , where I can find info, are always welcome.
