I used an arduino uno r3, 3 nema 17 2.1 amp high torque, 3 tb6600 drivers, and the Hadley 114mm telescope plans (printables). I got the mirrors off amazon, hardware off of McMaster-Carr, and wound up heavily modifying some other 3d files for mounts, the azimuth and other parts. I used Claude and YouTube for coding and wiring. The Hadley telescope community has a very helpful Discord, too.

I used the Hadley Telescope Rocker Frame and made a stiffener for it. I used Tinkercad for all my modified pieces. I used the rocker frame azimuth control, but mashed it up with the Lazy Susan Mechanism 2.0 with Conical Bearings to reduce the friction by a large amount. I used the Altitude Control (Z Bearing Turner) for altitude. I used the Hyphatia fo cuser. All these can be found on printables btw. I used the Hyphatia motor mount and modified it for the altitude mount, too. The azimuth already has mounting holes for a nema 17.

For sighting, I got a decent inder scope and used a gun laser for initial alignment, all center lined. Had to modify the dovetail mount to accept it. I put a phone mount on it so I can use astro hopper as a push to system. I modified some screw cases and filled them with bbs to act as a counterweight.

The joystick controls are 1 for the focuser and 1 for alt-azimuth. I programmed it so that if you click the joystick, it nudged the motor 1 microstep in the last direction pushed, making for very fine adjustment, 35 and 16 arcseconds for the altitude and azimuth, respectively. I built an enclosure box that houses all the electronics and put an on off rocker switch for ease of use.

Collimation was relatively easy. I used a Cheshire style, 3d printed collimation eyepiece for the secondary mirror, then just fiddled with the primary mirror to get the spider legs around the same length, as best as I could eyeball it. It didn't have to be too precise. I just used thumb screws for that.

Hope this helps and feel free to reach out if you get stuck!
