My idea came from trying to eliminate the need for a human in the loop. Probably why we stopped using pit stops for club racing because of the lack of marshalls. UF1 series that may or may not be a problem and we may have one there anyway. But I'm curious why you've found a human in the loop is important?

I'm a little out of the loop as to exactly what is being done because we've gone to plan B. Plan A was to use an on delay timer with a photo eye. But I would have had to buy most of it and Bernie came up with some old boards and such at work that we could use so it is obviously cheaper and will accomplish the same results.
