    Hi All,

    I just put the finishing touches on my Auto Antenna tuner, which uses a T-Network, driven by an Arduino Due, and also uses a Raspberry Pi with an LCD screen to display a Custom Build JavaFX Interface.

    I have posted an overview video on it on Youtube here:

    In the process of writing it all up, and hopefully having ARRL publish it, so others can build it.

    More to come and more videos....

    W9FTV and KD5RKO like this.

    Curious, did you use a program/library/api to do the display? I have some projects that could use a nice display showing temp, voltage, etc.

    Yes, there are a couple of JavaFX libraries out there that you can use for Gauges, but I used this one:


    I then used those to modify them a bit, to make them suitable for my LCD screen and for what I wanted to do with the tuner Display. It worked out pretty well.

    HI All,

    My second video in the series of this tuner is here:

    I will do one more that shows all the internals, but this one talks about how it tunes, and shows a demo of it tuning...
