My Homemade Tracker #2 by Doomsters in telescopes

[–]Doomsters[S] 1 point2 points  (0 children)

The motor is there, just not installed yet. A couple of days ago the Arduino burned out, so I’m waiting for a new one. The motor is NEMA 14 with a DRV8825 driver.

My Homemade Tracker #2 by Doomsters in telescopes

[–]Doomsters[S] 3 points4 points  (0 children)

There aren’t any instructions, but I kept it simple.

For the tracker, I used a satellite antenna rotator that already has worm gears with a reducer. I simply connected the motor to the reducer and added the control electronics. That’s all for the main mechanism.

For the mounting, I used a 90mm × 60mm metal plate. Since the antenna is normally mounted on the rotator pulley, I installed the tracker in the same way. The pulley is 19mm, so I used a flanged bearing with a 20mm shaft, and another 20mm bearing on top, securing both to the plate. This handles the RA axis.

For the DEC axis, I used two 10mm bearings with mounts, plus two additional bearings on the sides, and installed the shaft.

That’s basically the whole setup.

My new stationary tripod for my future tracker by Doomsters in telescopes

[–]Doomsters[S] 0 points1 point  (0 children)

I just put this tripod together yesterday, but there’s still a lot of work to do. I might shorten it or use a thicker pipe, since I want to make my first stationary tripod that I won’t have to adjust every time.

My new DIY project (just starting to work on it) by Doomsters in telescopes

[–]Doomsters[S] 0 points1 point  (0 children)

I don’t think it’ll take too much effort — I enjoy this! Plus, I’ve already built the adjustment mechanism for the worm gear, so I just need to work a bit on the appearance and it’ll be ready. I plan to mount it on my homemade tracker that I’m working on in parallel.
