Yes, it's a separate battery box. I used it for easier change of battery and with an already built in switch. Sent from Xperia Z1 using Tapatalk.

Ok, my focuser is almost completed. It's only fastened with velcro but this works just fine, might keep it as is. Hehe. Sent from Xperia Z1 using Tapatalk.

I couldn't help so I had to try this arduino focuser aswell and just right now I just got the stepper motor running. Had a few USB issues and bad performance of the motor. It all turned out to be 2 bad solders, that sorted it all now works. Now I "just" need to make things look nice and keep the electronics from the dangerous outdoors and order some pullies and belt - after I measured things 10 times, I'm a notoriosly bad with measuring and tools.. haha. Still, a fun project to follow and try out for myself!

Helt galet! Think I just spent 20 mins looking on your image, I just can't get enough of all the eye candy presented in this amazingly professional way. Well done!
