A series of videos demonstrating the VK4GHZ Nextion for K3NG Rotator Controller

Part 1 – Basic Az system

Part 1 looks at a basic azimuth-only system and introduces you to some of the functionality offered.


Part 2 – Elevation

Part 2 introduced elevation functionality and adds a decimal place to Az & El readings.


Part 3 – Moon & Sun Tracking

Part 3 looks at moon (EME) and sun tracking, context-sensitive help screens, and elevation calibration.

Part 4 introduces satellite tracking, and the process to get the TLEs (keps) into the microcontroller EEPROM.


5.0″ Nextion Release & 3.5″ Update

Adam walks you through a comparison of the new 5.0″ vs a familiar 3.5″ touchscreen, and it’s features.


Nextion V2021-01-06-01 Update

In this short video, Adam shows the changes in V2021-01-06-01.


K3NG Rotator Controller Mounting

Adam shows you how he crams his 5.0″ Nextion touch screen and custom K3NG rotator controller board inside an $8 box.


Nextion V2021-02-11-01 Update

Adam goes over the latest Nextion NX8048K050 (Enhanced 5.0″) firmware V2021-02-11-01 update for K3NG Rotator Controller.

Solutions to fix the crappy G-5500 +13V rail voltage drop on its Ext Control connector are also offered.
