Speaking of tap dance boards, below is a link to an electronic tap board I built and how I did it. It's been done before but some of you might find it interesting. Also, I'm working with a software programmer on creating a program that can analyze your tap sounds when you tap on an electronic tap board like the one I built. It's in the early stages and I can't say for sure whether it will ultimately work or not, but I'm very hopeful. I'll keep you all up to date as it progresses.
