An old friend ask if a prior project "using USB" would work for a Mud Bog event he had coming up, it would not, however I knew SI/OP could. So I came up with the following, which would handle his needs, then I just had to keep going with more features. He requested only a start and finish line to be logged, the driver just went whenever they were ready. Easy enough to add a staging line and a tree output with a red light for other events which I like, so I did.
