I built something like this a while ago, but mine is not nearly as nice. I etched an interlaced finger pattern on a big copper clad board, then put a tented piece of metal overtop of that, then some lexan sheets with a graphic inbetween them on top, so when you step on the arrow, it squishes the metal plate on to the circuit board and closes the circuit. It works remarkably well. And then the whole thing is powered by an Arduino that pretends to be a keyboard: https://github.com/jwalton/arduino-dancepad https://github.com/jwalton/arduino-dancepad
- jfim 6y agoWe built something similar to that in the early 2000s as well, although we used copper pipe hanging strap for the connectors, a J-PAC from Ultimarc for the PC interface and some plastic tubing for pushing the arrows away from the connectors. It worked pretty well too.
- GuB-42 6y agoI built one too, made out of wood (particle board). Arrows are spring loaded and when you step on it, it bottoms out on a metal bar, which make contact with another metal bar on the bottom side of the arrow. Ugly, noisy, but worked really well. For the electronics I just took a cheap gamepad and soldered the wires from the sensors to the button traces. Cheaper is usually better here. The gamepad was still functional, so I could use it to select songs and things like that.
