This is a 3-dimensional frame for the Dance Dance Revolution (DDR) game on the Sony Playstation 2. The pads are modifiable and can be used for other games as well. I wanted to build something for the kids in my Taekwondo class to have a game that can utilize hand techniques and timing.
It is slightly different from the video as I have modified and improved it since then. Here is Jacky demonstrating it. First time she ever tried it!!
Four Pushbutton switches (momentary ON) - Radio Shack 275-1566A for the square one pictured. The round ones are better but I don't have the number. The other difference is that the round ones have screw-type terminals (better) and the square one pictured has solder-type terminals. If you will be moving it a lot you may want to get alligator clips as well.
Small gauge wire - Radio Shack 278-1218. I found afterwards that a couple different colors helps to keep everything straight.
Yes, you have to be fairly accurate to hit the center, but it is pretty forgiving, and I rarely have misses (when my timing is right, anyway!).
nice instructable tho...i'll consider doing it sometime
