Step 1: Gather Electronics

Materials:
Wave Shield - Adafruit
Arduino Uno - Adafruit
SD Card - Adafruit
ADXL335 Accelerometer - Sparkfun
Female Headers - Sparkfun
Toggle Switch - Jameco
9V Battery Snap - Jameco
9V Battery - Adafruit

Optional:
X-Mini Speaker (surprisingly good sound quality for the size) - Amazon 
Web Belt - Most workwear clothing stores

Tools:
Soldering iron & solder
Wire strippers
Diagonal cutters
3D printer for the case

Step 2: Solder & Test the Wave Shield

First step is to solder the wave shield together. There is already a great tutorial from Adafruit for soldering it together. If you are going to assembling this inside of the 3D printed box, you will have to leave off the black volume control knob. You can still control the volume by twisting the potentiometer, it will just be slightly less convenient. 

In order to program the wave shield you'll need to download the WaveHC library and put it in the libraries folder within the Arduino program files.  

Audio files need to be converted into 22KHz, 16-bit, mono .wav files. If you don't know how to do this, follow this tutorial using either iTunes or Audacity.

My experience with the Wave shield is that it can be fickle. I highly recommend loading a formatted song onto the SD card and testing out this shield with this example. This example should automatically search for any properly formated wave files on the SD card and play the songs all the way through. If it doesn't start playing, check the serial monitor to see what error messages you are getting. If a song starts playing, you are good to go!
If only this was here before the Harlem Shake!

Do you have to have a 3D printed box, or is there another box type object you can put this in? I do not own nor do I know of a place where I can use one

I'm using the box mostly just to attach the electronics to my belt. Radioshack sells project enclosures that come in various sizes. You could probably find one that the electronics could fit into.

GREAT!!!! Is the accelerometer ADXL345(https://www.sparkfun.com/products/9836)?
I think that it is ADXL335(https://www.sparkfun.com/products/9269).

Thanks for pointing that out. It is the ADXL335. I'll update it.

This is the best thing ive seen on here so far.
Im definately going to make this. oh yes indeed. it will be just so much awesomeness.

LOL! Nice video!
I see as-seen-on-tv exercise product potential. You should market it.

OH GOD I NEED THIS!

I'll use it to play funk music as I walk down the street! :D


er..looks like its not really responsive. do you think the lag is in whatever youre using for a sensor? accelerometer of some kind?
ElectricSlim (author)  the new voodoo1 year ago
It is using an accelerometer. I didn't spend a lot of time trying to optimize the code but just enough to get the proof of concept running. When you're moving the box in your hand you can get it to start and stop without any lag but dancing sometimes creates a little bit of lag in the shut off.
want!
YES YES YES

I love this project :D
