Hi Walt,
When you say it "misses a command", do you mean that you don't get the touch
sensor pressed once in a while? Or the motor doesn't turn when you want it to?
If it is the touch sensor issue, maybe the round brick+boat plate that are not
close enough to the touch sensor. Maybe you could make that spring loaded?
Or is it that the switch is misaligned when the touch sensor is pressed?
