Tomorrow There Will Be Wind ( Automatic Windchimes )
A performance of playing an Arduino controlled set of wind chimes.
Vibration motors are activated through a motor driver creating divisions and
polyrhythms based on various “states.” First iteration prototype with beer
bottle activation.

4-Note Bottle Blowing Instrument

I have always loved the angelic sound that is produced by blowing into an empty glass
bottle. The combination of wind noise and the ringing sine wave tone that resonates out of the
bottle creates a fascinating timbre that is impossible to perfectly replicate digitally. What if you
could mechanically create this sound and produce beautiful melodies to perform with it? This is
what inspired me to create the 4-Note Bottle Blowing Instrument. This device contains four
small fans attached to DC motors mounted in a specific way to effectively blow air into each of
the bottles. This causes them to resonate and create a fairly loud sine tone. Each bottle is
individually tuned by raising and lowering the amount of water inside them. Using an Arduino,
the instrument will then perform a sequence of notes by fading the fans in and out from left to
right. This allows musicians to tune each bottle accordingly and create any four part melody
they desire.

Liquid Light Movers

This work in progress was inspired by a love of old school liquid light shows and a fascination
with the precise engineering of the inside of a moving head. The goal is to repurpose the
internal mechanisms from used Clay Paky Alpha Spot and Alpha Wash fixtures to create an
animating liquid light show in the beam of the fixtures.
I began with the Alpha Wash fixtures due to the less complex internal layout. However, due to
the limited range of beam effects in the fixture, the color wheels were my first choice for
modification. The challenge with the color wheels was adapting the rotational movement of the
color wheels into the vertical movement of a plate.
The first iteration of this design is made of two clear discs connected by a silicone tube to create
a sealed container that is then filled with the dyed oil and water. The two discs can then be
oscillated against each other through the use of a ridged gear on the inside of the metal plates
holding the discs. This creates the fluid movement associated with traditional liquid light shows.
In addition, the entire mechanism can be moved in and out of the beam to add or remove the
effect. The prototype of this iteration is still in development
