DJI Digital FPV Antenna Tracker

Description

Based on the famous "braitenberg" robot and designed by Alex Greve AKA ibcrazy, this is a working and tested FPV antenna tracker board. This circular tracker board also doubles as a turn-table top for you to mount all the electronics to complete the tracker. No need to make a top for the turntable. Note that you are receiving the working tracker board only.
This tracker will continuously point all 4 directional antennas of your DJI Goggles V1 (in 25.4mbps mode only) continuously at your drone which is having the DJI Digital FPV Air Unit or Caddx Vista. No more guesswork or worrying that your head is not turned to the correct direction to point your directional antennas at your drone when you are flying digital FPV. This is a GPS-less tracker so it is suited for small drones that do not have the payload to carry additional GPS electronics which are typically required for a GPS antenna tracker.
Simply connect a regular analog servo (with its stop-gear & potentiometer removed) and solder the direction-control wire of the tracker board to the potentiometer's middle leg's pad on the servo's PCB
. Then connect the 2 rssi wires of the tracker to your two 5.8ghz receiver modules, and you are done with the electronics. To use this tracker for DJI Digital FPV, the two receivers must support RaceBand channels (to listen to the frequency of the DJI Digital FPV Air-unit or Vista).
3D-
print your own turntable’s base (with the STL files provided in the description of the video below), to complete your own unique GPS-less antenna tracker system, to start enjoying long range digital video on your palm-size drone. And what's even cooler is, it looks like a miniature radar system at your local flying community! Do note that you could make the “tripod” or the “head mounted” version, the link to download the STL files for both versions are provided in the YouTube video below.
