I have an idea for making logochips have numerical wars. I have a one on one chip program that is 80%done. I will need logochip V2 in order to have one chip connected to two or more other chips with my current protocol scheme.
I have also come across a good source for 7segment led’s with built in logic. I will need a lot of these to display the numbers in the chips with minimal ports for decoding. I would like to find green ones though.
An Engineer’s Review
Ulrich Museum March 2nd, 2007
Thomas Engdahl
I was given an insightful tour of the Ulrich Museum and the adjoining facilities by Joshua Unterman. He first showed some of the processes of the art before exposing it in order to help the viewer understand the art better. Most specifically he introduced the basics of printing and showed some of the equipment. Then we proceeded into the Ulrich Museum from the back entrance.
The piece that really caught my eye was “Double Transversal†by Richard Serra. This was a very large print. The piece is very large in scale and occupies most of the wall it is hung on. It was also one of the first pieces visible when coming in from the back entrance. The print is very monochromatic; the black creating very large negative space opposed to the white walls of the room. The piece’s parallelism with two identical shapes create a very interesting illusion when view from a moderate distance both giving the shapes depth and also making the viewer doubtful of the two shape’s equality by use of devices such as skewed and concave perimeters. When viewed at a closer distance, more depth is exhibited from the large amount of ink used on this print. The inks clump up creating an almost metallic texture, like panted over oxidizing iron. Of course when viewed from the side the piece has no depth as all prints are flat, but the piece seems to merit such practices.
Another Piece that was discussed was “Torn Leaf Hold to Fallen Elm with Water†by Andy Goldsworthy. What was viewed was not the piece itself but a picture to document a temporary piece or ephemeral work. Goldsworthy used limited tools in this work, constructing the entire piece from trees and leaves and other elements from the surrounding stream. This clash between the eternal nature of the wild built on the brevity of life is portrayed by the platform that is the elm and the construction of the artist on the elm torn against the elm, revealing elm beneath the construction of leaves.
The last piece I want to discuss is “Landscape (detail)†by Kristen Beal –De Gandmont. This installation consisted of many small uniform pieces of plastic mounted to the wall. The white light shining from above the piece then created patterns as it affected by the properties of the plastic. The piece created an interesting three-dimensional presence when the light was viewed in conjunction with the plastic, making the plastic look like crystalline or solid glass. Upon further inspection, these fixtures were flat pieces of plastic shaped like raindrops. The idea of rain is further exemplified by the dense distribution of the plastic figures toward the top and a thinning number of figures as it worked its way to the floor. All the droplets faced downward which is important in a portrayal of rain and gravity.
I met with my group this friday and here is our idea.
We want to harness some kind of standing wave or magnetic material on a small scale and use the logo chip to fauilitate it. Possible use light in conjunction. These princibles may apply to a large project idea.
Group members:
Thomas Engdahl
Nick Meyer-Hesler
Muhammad Zahid
Andy Zerngast
John Carper
Our schedule is to research and investigate phenomonon for the next week. Next week (Friday) we will start building the device. Andy is going to look at ferrofuilds:How to attain/make it. Nick will look at some of the standing wave materials, diaphrams. John will investigate sound generators and possible music moments that could happen with PD. I am going to look at drivers (speakers) and the dry/salt standing wave patterns and lights with the logochip.
Here are some sources we pulled up during the Lab today.

My Programs are beginning to get a little lengthy. I will start providing a link to my program-wiki instead. This week I added functions relevant to the material taught this week to my program that I created last week. I created “equi-tempered beeps” to help reduce difference in beep length versus wavelength. There is also included the “S” or the sync functions for better network timing across more than one chip. Also register A0 has been converted to a analog input. In this program a potentiometer can be used to change the tempo as the song is being played. I also updated the resting functions.
I finished my Mario Trio Program. I have been able to get 2 parts of the song to play at the same time. I need to get a 3rd logochip to see if it will work with 3.
Here is the program and some of my networking ideas.

It took a while to get this to work. You need at least 3 devices. You also need to make sure they all have a “common ground” and they are all turned on within 10sec of each other. There is also a master or starting version to the program so that the one primary device will start the loop.

Here is a demonstration of what square waves look like.
Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. Download the latest version here. You also need to have JavaScript enabled in your browser.
This is a stereo square wave(phase difference 90 degrees). It should be a square on the X-Y plotter.

Here is a chord of square waves. Notice the “constructive interference” as more notes are brought in. One note plots 1^2=1 squares, Two notes plots 2^2=4 squares, Three notes plots 3^2=9 squares, and so on. So it’s N(#notes) squared! Playing certain chords will trace only certain parts of the squares depending on their harmony.
