How heavy is the scope?
For X axis, you could make a turntable, or just buy a "Lazy Susan" and modify it to be turned by a motor.
For the Y axis, assuming you can mount it at the center of gravity of the scope, another stepper should do it.
For positioning, you could use a tilt compensated electronic compass, or something like an HMC5883L and any accelerometer with some code to save money.
If you mount the compass above the center of the turntable & center of gravity of your scope rough positioning will be easy.
Thanks for taking a look at my post. Long story short, I'm trying to make an IoT telescope powered by the pi. Which sounds cool, and the software was super interesting to work on. But I am drowning in questions regarding the physical design of my project.
I have a 12v Stepper motor (and successfully wrote a java program to interface with it). I want to learn more about what kind of designs exist for a rotating platform (just trying to peg the X axis movement with this one). Or even just find a good resource (book, website, blog, etc) that maybe explains a bit more about hardware "design patterns" (if such a thing exists). I'm not looking to solve this one exact problem, per se. I'm hoping to find something that can help me start to think like a robotic/mechanical engineer/hobbyist who can do more than just program
Any guidance would be greatly appreciated. Thanks!
