Live audio demonstration being able to listen to the combined motor revs of the Blackout Mini H Quad on a 7" 5.8 GHz Receiver/Screen.
This uses a cheap electret mic insert and a simple mic preamp based on a TL061 Op Amp.

An introduction to the VK4GHZ Nextion HMI touchscreen interface for a K3NG Rotator Controller.
Part 3 Introduces moon and sun tracking, and discovers context-sensitive help screens. Elevation calibration is also discussed.
Part 2 introduced elevation functionality and adds a decimal place to Az & El readings.

Adam discusses why it is important to power your Nextion and MCU up at exactly the same time (ie; off the same power rail), and some basic checks you do if your HMI is incorrectly coming up in the basic Az only cheeseburger mode.
Both 3.5″ and 5.0″ Nextion touchscreens for the K3NG Rotator Controller receive an update and the updates are discussed and demonstrated.
