Executive Summary

We got the idea from Makey Makey which is a invention-kit to use everything to be Keyboard. like banana, water, even cat. For this project, we created a Bonekey Bonekey to play with sound. Our Bonekey Bonekey uses banana as keyboard to play piano tones. This design is consisted of a main microcontroller, a PCB board, a USB sound card, and an audio player. We use Beaglebone to get the different input informations and produce corresponding tones to the audio player. One of human's wrist is mounted by reference ground and human can use either figure to touch bananas to produce different tones. Our Bonekey Bonekey will not only use bananas as inputs but also apples, water and everything.


If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.

Installation Instructions



Build Csound from source Beaglebone. The BonekeyBonekey need CSound6 but the apt-get version is still CSound5

bone$ sudo apt-get build-dep csound
bone$ sudo apt-get install cmake git
bone$ cd ~
bone$ mkdir csound
bone$ cd csound
bone$ git clone https://github.com/csound/csound.git csound
bone$ mkdir cs6make
bone$ cd cs6make
bone$ cmake ../csound
bone$ make -j2
bone$ sudo make install
bone$ sudo ldconfig
bone$ cd cs6make

MakeyMakey github link https://github.com/MikuZZZ/BonekeyBonekey.

User Instructions

Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.

When everything is installed, we can play with Makey, Firstly connect the USB sound and the audio player to beaglebone. Then connect the 7 input wires into 7 bananas, and wire the reference ground to one of your wrist. Use your hand to touch bananas to play sound!


Here is where you brag about what your project can do.


Theory of Operation

1- Input

   * The bananas are the inputs of Bonekey Bonekey
   * By touching the banana, the input will be shorted to ground.

2 - Transistor Switch

3 - GPIO Interrupt

4- Csound

Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.

Work Breakdown

  • PCB
  • GPIO read in
  • Csound play sound

List the major tasks in your project and who did what.

Also list here what doesn't work yet and when you think it will be finished and who is finishing it.

Future Work

Suggest addition things that could be done with this project.


Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
