This page refers to my Autonomous Satellite Tracker article in the March/April 2016 QEX. All updates will be posted here.
The Tracker is now available using the ESP8266 processor, the same one used in my HamClock. This eliminates the need for the Arduino, ethernet shield and the TP-Link. The wiring diagram and interior view are now just this:
The wiring for the Servo controller, 9 DOF Sensor and tilt and pan servos is the same as in my original design. Note the change from 5 to 3.3 V supply for which the Huzzah EN is grounded. If you use a 5 V supply then leave EN disconnected.
The new sketch is dated 2023-05-30 here. Set up the Arduino IDE for the Adafruit ESP8266 Huzzah the same as described in FAQ 1 of my HamClock project. Use the IDE Library manager to also load the following libraries:
The Tracker functions the same way as described in the original article except how it connects to the network:
Servo City seems to have discontinued the gimbal I used. The closest they seem to have now is this one which can be connected as shown in the lower diagram to form a pan-tilt platform.
Thomas, DL2TW, has made code changes to add a TFT status display. I've not tried his changes but you can get his zip file here if you want to try them.
Kishore, A45WI, is building his own platform using these monsters (demo video here).
Let me know how it goes for you,
