For my part I don't know if it's hard code developer or more mad hacker, but it is fun.
Here is a picture of the latest addition, an L-Network ATU built in the uBitx case, driven by two servos and controlled by an Arduino mini pro linked over I2C to the Raduino.
It is now working well (80m to 10m) but needs cleaning up, shields (just to make sure) and a nice display of SWR and Power on the LCD.
More details to come.
All the best,
