Music Box- Phys. Comp. Midterm.

Tuesday, October 23rd, 2007

Continuing on our research of sound and the Arduino chip, we have created a musical instrument after a lot of hours spent on the comp version. We have called this instrument “The Light Wave DJ” and are in the process of developing a web site for it. What you will see below is a video showing the actual project we had in mind. It is basically an Arduino chip coded to receive input from 2 photocells and a Potentiometer and then use the variables to produce square frequencies that produce sound on the speakers. The speakers are assigned to play the sound one at a time to produce a looping effect.
Here is the Video… I need sleep.

Talk by Marius Watz at ITP.

Friday, October 19th, 2007

Marius Watz gave a talk about digital media and digital fabrication of art. He is a Programmer that began his career in the “Media Revolution” of the 1990′s He talked about the difference between “Strong” and “Weak” Artificial Intelligence. He talked about non-human art theories and his view of the direction of computer generated art. He is also the person behind Generator X and The Flickr Group Digital Fabrication. This is an image from Marius’ Flickr Web site:


Preparing 3D modles in Maya

Thursday, October 18th, 2007

For the Class Physical to Virtual and Back (P2V) we are designing 3D models in Maya and then exporting to Virtools for programming and interface building. This is a fictional fighter jet I made. Soon I will be exporting this to Virtools so I can program it to respond to sound sensors and video feeds.

Here is a video of the 3D model in progress.

Text Rain with Potentiometer Control

Thursday, October 18th, 2007

I decided to elaborate on my “Matrix” text rain and hook up some Arduino control to it.

I programmed the Arduino to communicate with my Powerbook using a 9600bps signal. The Arduino was hooked up to a breadboard with 3 sensors; 2 potentiometers and a photocell. I then programmed my text rain to read the 9600bps serial connection with the Arduino and used the variables from the 3 sensors to manipulate the color. The variables are passes from the Arduino to Processing in a 3 byte digital format. Below you can see the result.

Text Rain!

Wednesday, October 17th, 2007

For ICM we had to code a Processing file to display a text of some sort. I decided to go a little towards the POP end and create raining letters like in the movie “THE MATRIX” Here is what the file looks like and the code! =)

Phys. Comp. Midterm Project II

Tuesday, October 9th, 2007

Moving on with the concept for out midterm project I rigged a Piezo buzzer to a potientometer to see how a change in voltage frequency will effect the buzzer.

After working on the Buzzer I included 2 photocell sensors to the circuit of LEDs that I created previously. The goal is to try and change the direction of the electric impulse of the LEDs with the two photocells, after a lot of trial and error with the code, Success!

Eventually we (Borna, Jay and I) want to incorporate the Piezo buzzer into the LED circuit to create an impulse of sound and controll it with the photocells.

Phys. Comp. Midterm Project

Sunday, October 7th, 2007

For a midterm project Borna, Jay and I are creating a circuit of lights and sound that turn on and off in a looping sequence. This is an attempt number one to illustrate the general concept.

We are rigging a circuit of 8 lights and thinking about using Piezo Buzzers in the mean time to create sound. The Arduino will allow us to control what lights will turn on and off. We are thinking about using this electrical impulse later as a switch to trigger a more intricate sound patter.

Later on the potentiometer will be swapped out by two photocells that will detect the movement to trigger a switch in the direction of the blinking LEDs and sound.

Here is a simple prototype of the circuit:

And so the bunnies go…

You may be wondering; gee why would anyone use Processing over Macromedia Flash?

The answe of course is; Bunnies!!!!
Check them out! They bounce they are adorable and they never stop moving!



Servo Motors.

Tuesday, October 2nd, 2007

This week I wired my Arduino and my Breadboard to take the reading from a potentiometer or a photocell and use it to turn a Servo motor at a specific angle. Here is the video I managed to capture.

This is a video clip showing the potentiometer
controlling the Servo motor:
