The idea here is to build a wearable virtual guitar that is to be controlled with two hands much like playing Air Guitar. It has been created and prototyped during a two weeks project at
The aim is to get the feeling of playing a real guitar. The AIRduino Guitar is made of one glove and one stick. The glove is used to set the tone and the stick to trigger the sound.
To perform such trick, we used an accelerometer and an ultra-sonic sensor (see Step 1 for concept description).
Take a look at the video demo to get a more precise idea of how it works, and get to work to build your own!
The AIRduino Team:
David Fournier, Jean-Louis Giordano, Monireh Sanaei, Maziar Shelbaf and Gustav Sohtell.

The guitar controller is divided in two parts, left-hand controller and right-hand controller.
By left-hand controller the player can bend his fingers and press the glove to change the pitch of the tone.
The right-hand controller is represented by a stick which has to be shaken to trigger the sound of the air-guitar.
Player can also change the distance between right hand and left hand in order to pitch the tones, simulating the different frets on the guitar neck.
To perform such tricks, the main components are an accelerometer to "feel" the stick shake, an hacked ultra-sonic sensor to measure the distance between the right hand and the stick, and conductive fabric to build the glove.
All in all, it is an fairly easy to build toy. The only tricky part would be the ultra-sonic sensor hack which requires some dexterity. You will need some basic electronic skills to understand the instructions, and also to find out what you did wrong when you messed something up and the guitar doesn't work in the end. We have been there. :-)

Awesome project anyway
We will update this instructable during the week. We couldn't do that earlier because we didn't take pictures when we build the first prototype. Since we are making another one we will be able to write more detailed instructions now.
If the finger is not pressed, the input to its pin will be 5V, and if it's pressed it will be 0V, hence HIGH or LOW state for the arduino.
One part of the switch is the large conductive fabric in the palm of your hand and the other part is the small conductive fabric on the top of your finger, the finger part going to the pins and the palm part to the ground.
We plan to make a more explicit schematics in a near future, so check for an update later this week! ;)

Anyway, hope you can still submit yours and have fun.
