Hi everyone. I have a project on mind but I really don't know where to start. I'll try to explain it....
I am a fencer and I want to make a game for the kids I train. The game is to try to touch the other and not to get touched. I tought about making some kind of t-shirt with five leds and a pressure sensor at the front. Each time you hit on the front one led would iluminate.
You don't really want pressure sensing you want contact sensing. You could do that with conductive fabric, and using a low current AC source attached to the foil, so that when it contacted the fabric it would register as an AC current, voltage probably wouldn't even have to be that high.
In such an active environment capacitive sensing is probably not going to work, straight voltage detection is far simpler and more reliable.
Just found out how they do it professionally. Apparently there's a simple contact switch on the tip, seeing as how only tip contact counts in fencing. That'd be extremely easy to make, it'd be easier to put the LED's on the foil though.
