Hello! A community question regarding the +/- functionality:
The Digitast buttons specified in the build instructions seem impossible to find, but I suppose any momentary switches could work. Since there is no proper wiring diagram i just wondered how you'd go about wiring them in (supposing they are standard pushbuttons with stabdard 2 lug-layout).

I have the digitast-Buttons, they are technically 2 switches in one button. One is "on" when the switch is pressed, the other one is "off" when the switch is pressed. So the digitast button has 4 pins. I used a multimeter to determine wich pins are connected when i push the button. You will only need the "closing" switch (Pins 0-1) of the digitast button.
So it would be possible to use any kind of momentary switch wich closes the contact when it is pushed down.
