Who doesn't want to dance around on a giant floor piano like Tom Hanks in Big?

There are many great Makey Makey piano tutorials on the web. We wanted to make a version that really looked like a piano and that worked without participants having to hold on to a wire to ground themselves. This is what we came up with!

Step 1: Gather Supplies

You will need the following supplies:

  • 4 Foam exercise tiles
  • Makey Makey
  • Aluminum foil
  • Duct tape
  • White tarp
  • Wire
  • Raspberry Pi, keyboard, mouse, and speaker OR laptop

You will need the following tools:

  • Wire stripper
  • Scissors
  • Level
  • Measuring tape
<p>So, if I'm understanding right, there is duct tape between the layers of foil, which is a buffer that keeps them from completing the circuit until it's stepped on. Is that right? How does pressure all of a sudden turn duct tape into a conductor? Am I misunderstanding something? How well did it work?</p>
<p>Nice idea,I really want to know the sensor you used is the touch sensor or pressure sensor?If you put bare foot on the tin foil mat may trigger the sound.but the foil is covered by duct tape,not to say you trigger the sound with your shoes on,so it looks like you used pressure sensor.</p>
<p>We did not use a sensor. I'm sorry. I wish I understood more about WHY this works, but I don't. I just know that it works.</p>
<p>Could you be more specific about the wiring,So you just put 'trigger wire with a layer of tin foil at one end in between the duct tape and the exercise mat' right?</p>
<p>Here's how one key is layered out from bottom to top: exercise mat-wire-tinfoil-duct tape-wire-tinfoil (secure edges with duct tape)-tarp.</p>
<p>Big Thankssssssssssssssssss.</p>
<p>I think by &quot;Arduino&quot; you mean &quot;Raspberry Pi&quot;, right? Arduino is a pretty bare-bones microcontroller, but the device you have looks like it runs Scratch on the web. Could you clarify?</p>
<p>You're absolutely right! Thanks for catching that. I'm making corrections now.</p>
<p>Where's the ground position between piano;s key and board? suggest me please..</p>
<p>There is no separate ground wire for people to hold in this design. The ground wire is attached to the board and separated from the trigger wire with a layer of tin foil and duct tape.</p>
<p>Crazy! This reminds me of Dance Dance Revolution, but DIY. Super cool.</p>
<p>Very nicely done, this looks like loads of fun!</p>
<p>Thanks so much! </p>
