Tiger, you are may Hero :thumbup:
I try to build a home-cockpit since two years.
Therefor I use the electronic of an keyboard.
It works nice, but it's not possible to use switches without
some eletronics (switch 'on' is the same like press down the key :()
I searched a long time to find a microchip like "yours"
Now I cell my car, the horse of my girlfriend and build my cockpit :pilotfly:
yeeehaaaa
Very nice work :thumbup::thumbup::thumbup:
Yours
