I would like to make a bounce juggling piano like in this video:
, I think this is fake.
I would like for it to be just some thin sensors or something I can lay on the ground and bounce the balls on? I cannot use wood or cardboard because that will ruin the bounce. So I am looking for some good sensors I can use for this that is easy to read from the arduino. I have been thinking about piezo-elements, but I am not sure how to separate them unless I have separate blocks for the separate keys, but then the balls will fly away if they hit the area between the different keys. Do you have any ideas for sensors for this, the keys have to be quite a bit larger than the balls.
I am thinking about using the new Music shield from Sparkfun to generate the different sounds.
