Excellent, I will add the one pot and the one mode switch as planned. Any particular pot I should use? The switch directly to the left of the big starter switch is indeed left to right. The 2 switches above that are up and down. The one below the left joystick is side to side and the one below the right joystick is up and down. The switch to the top right of the starter is side to side as well. This is really an awesome project. Don't know if I will have it ready for the Maker Faire here in March, but I am going to try.
