Do you want to take over the world? or just annoy your roommate? This should probably do the trick (to annoy someone, taking over the world is a little far fetched)

Step 1: Materials

For This Instructable you need:

* a piece of tin foil (or other conductive materials)
* electrical wire
* tape
* Polyurethane sponge (with scouring pad)

Tools:

* a knife (i used my scalpel) or scissors

Hardware:

* hacked USB keyboard

Step 2: Rip It Apart

Start out by removing the scouring pad from the sponge (we only need this part).
Cut it in two and cut a round hole in the middle.

Step 3: Fan It Out

Strip the end of a piece of wire and fan it out, 
Tape this to a piece of tin foil and fold it to the size of the scouring pad.

Repeat this step

Step 4: Tape It Down

Place the foil wire combination on two sides of the scouring pad and secure them with a piece of tape.

Step 5: Hook It Up

I taped mine to a cap and hooked them up to the 6 and 7 button of a keyboard  and scripted a couple of lines in processing to create the noise.

The .zip files contains the script.


You wil need to use a <a href="https://www.instructables.com/id/Hacking-a-USB-Keyboard/" rel="nofollow">hacked keyboard (https://www.instructables.com/id/Hacking-a-USB-Keyboard/)</a>. hook up de soft buttons to the keyboard interface and use the software <a href="http://processing.org/" rel="nofollow">'Processing' (http://processing.org/)</a>. I added the <a href="https://www.instructables.com/files/orig/F9F/Y58D/HD4VMTDO/F9FY58DHD4VMTDO.zip" rel="nofollow">script and sound</a> to step 5.
Um, how does this work?
