Human: 13-Element Yagi Antenna with Azimuth & Elevation Rotator Material Used: * 1.65m Antenna/Camping Balkon Tripod from eBay * 2000 x 15 x 15 Aluminum Rectangle Tube for Antenna Beam * Two 2000 x 20 x 20 Aluminum Rectangle Tubes for Rotator Frame and Azimuth Axis * Unknown Length x 8mm Aluminum Tubes for Yagi Elements * One 12mm Aluminum Tube for Yagi Radiator * Plenty of M4 Screws with Nuts and Washers * 4mm Plywood for Rotator Sides * Two TB6600 Stepper Drivers * Two NEMA24 Stepper Motors * Four Endstops from eBay * Wemos Lolin32 as Rotator Controller * PLA Filament (ABS Was Bending Too Much for Large Parts) See My GitHub Repository at [github](https://github.com/yeckel/ESPSatTracker) for ESP32 Bluetooth Rotator Controlling Software. The Building Process Is Relatively Straightforward: + Print the Corners of the Cube + Cut the 20mm Tube to Twelve 20cm Long Pieces + Connect Pieces to the Frame + Add Four Plywood Walls So They Fit Together + Drill Holes for Axis Slightly Smaller Than the Bearing + Attach Gears + Add Gear to Stepper Shaft (I've Simply Pressed It On; It's Holding) + Measure Where to Place Steppers So the Gear on the Stepper Fits + Drill Holes for Steppers and Screw Them into Place + Add Azimuth and Elevation Axis and Glue Them in Place + Endstops Are Attached to Holders (However, They're Actually the Only Pieces Breaking When the Gear Overruns; The Software Is Still Not Utilizing Them)
