This page refers to my Autonomous Satellite Tracker article in the March/April 2016 QEX. All updates will be posted here.
Update 2018 July 29: 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.
Update 2020 Jun 16: Changes:
The new sketch is here. Set up the Arduino IDE for the Adafruit ESP8266 Huzzah exactly the same as described in the first answer in the FAQ tab of my HamClock project. Use the IDE Library manager to also load the following libraries:
The Tracker functions exactly the same way as described in the original article except how it connects to the network:
Servo City seems to have discontinued the gimbals I used. One builder reports he will try to use this one although I have not tried it myself. Without the extra 5:1 gearing it's not clear whether this can hold an antenna.
Thomas, DL2TW, twinterfeldt at web dot de, has made some code changes, such as a TFT status display and allowing more characters in the WiFi credentials. I've not tried his changnes but you can get his zip file here if you want to check them out.
Let me know what you think!
