DIY Your Antenna Rotator/Satellite Tracking Device
After finding that purchasing a tracking device for his satellite dish would be quite expensive, YouTuber “Tysonpower” decided to simply build one himself.
He made it with 3D-printed parts and extruded aluminum that uses a pair of NEMA23 stepper motors for movement.
While it doesn’t quite work with the dish itself due to its offset weight, the concept was successfully used to track weather satellites using a VHF Yagi antenna.
Control is provided via an Arduino Nano, which interfaces with a computer over USB serial that provides satellite information.
All you need for this project is:
4x 6008 2RS bearings
2x Aluminium pipes 40x3mm
2x Optical endstops
19x 2020 Aluminium extrusion, each 20cm long
8x inside 3 way corner bracket for 2020
T-Slot inside corners
M4 hammer nuts
2x Nema23 brackets
4x 625 ZZ bearings
M3x10mm grub screws
2x 40T GT2 pully (5mm inner diameter)
2x 20T GT2 pully (6.25mm inner diameter for motor)
2x 160mm closed loop GT2 belt
Arduino nano or similar
