Oh my dearl lord what a nice nice and nice upgrade duuuuuuude, one of the best during the last 5 years!
Sadly I dont understand a word of german...is the hardware and software available for anyone or is it custom made?
Thank you for the flowers
the hard and software is built on Arduino, all components are available in the open market. In the Arduino forum I have written a thread (https://forum.arduino.cc/index.php?topic=589039.0) is in German, but there is still the Google translator .....
