I'm going to be building a lap counting rig, and was looking for
pictures of other systems in use. Any help will be appreciated.
John,
The PGRC guys have a nice flip card system. It uses some welded aluminum channel to hold the cards, and they have a stand to hold it. Contact Rick Moreland. Jim Katz knows how to get in touch with him. I have a couple of pictures I will try to find.
I have a program that will print 7 segment digits for making masks if you don't want to buy vinyl numbers. And at 40+ to 80+ numbers, they add up.
