  • There are already several software solutions for polar alignment; NINA, ASI Air, SharpCap, StellarMate etc. Of those I think only NINA is open source. They all use the primary imaging camera and the mount to calculate the polar error and display that for the user to manually correct. So the alignment part is already solved.

    You’d need to figure out a good mounting solution for whatever servo/motor used (and this will likely be very mount dependant) and then just translating NINA’s (or whatever’s) output into actions for the motors.


  • Pretty much this. Combined with how easy it is to install VaultWarden (docker ftw), it was a no brainer for me.

    Also, my little home server is a WAY less juicy target for someone looking to steal and sell a bunch of passwords.

    Been running it for probably about 2 years now. No ISP outages but a couple self-inflicted ones. Didn’t even notice the outages in the BitWarden app/extension.




  • Consider a used HP Elite desk SFF (small form factor) with a 6th Gen or later Intel CPU (or the equivalent from Dell or Lenovo). Space for 2x 3.5 HDD for data, an nvme m.2 slot for your OS drive, and a couple of pcie expansion slots.

    1.) it’s cheap and replacement parts are plentiful 2.) 6th+ gen Intel CPUs have Quick Sync for hardware accelerated transcoding 3.) fast interface for the OS drive, and room for a pair of multi TB HDDs in raid. 4.) some expandability 5.) power draw isn’t horrible, but nor is it great.

    OS wise, lots of options. Ubuntu server LTS is my general go to because it’s easy to Google stuff for and is stable. And I don’t need a desktop environment. I then run the services in docker.

    Note about Intel Quick Sync when running headless: you may need a display emulator to get the system to enable it. The HP bios (and maybe some others) don’t have the option to permanently enable quick sync. The display emulator tricks it into thinking a display is plugged in. You can get them on Amazon for under $10.
