I built an air hockey table with my friend but it didn't come with a score board.
So I found some extra garage door safety sensors laying around, and I figured I could some how use them to make a counter with some 8 segment displays.
Problem is, I have no idea HOW to make a circuit from scratch, and circuits from most websites seem pretty unreliable.
(This forum seems like a good place to start from what I saw)
Anyways...(back on topic), could one of you guys come up with a circuit that could use these sensors (as the puck passes through them) to keep score of the game as we (my friend and I) play air hockey.
*edit
I am currently learning electronics at a trade school so I have parts in shop that I can use
