Instructable Filming

This week we did the filming for our instructable video on making a laser cut box! Many thanks to my group members Yeonhee and Caleb. Before we started I was pretty apprehensive about filming but we worked thoughtfully and efficiently through each stage of our filming. There are about 9 scenes in our video so we did a lot of lugging camera equipment around. We even took everything to Canal Plastics to film in their store. The store owners were kind enough to let us film there.

In total we have at least 40 to 50 GB of video. We did multiple takes for each section, sometimes using two cameras at the same time. We also created two laser cut boxes, because the assembly step involves using acrylic welding and obviously that can only be done once. Two boxes made the success of each shot less critical.

Experiments With Sound

Upcycling a Speaker

A year ago someone gave me a birthday card that played a song when the card was opened. As I was interested in learning more about circuits, I took apart the card and saved the electrical components for a time when I could dissect them and learn more about how they work. Last week we learned about sound in our physical computing class, so it seemed like a good time to put the inexpensive speaker to good use.

To upcycle the speaker I rewired it to give it red and black wires for the speaker's positive and negative terminals and a header pin to go into a breadboard. I also built a 3D printed case as an assignment for my 3D printing class.

Color Palette

This week we learned about the use and importance of color in design. Our assignment is to create a color palette that represents us and then use it in several compositions.

This is the color palette I came up with. The primary color is #882222 which is currently the specific shade of red used in my blog's side menu. I happen to like the shade of red a lot. The other colors were selected using Google's Color Selector Tool. I tend to not like the color blue that much but I thought it did compliment the reds quite well so I decided to stick with it.

First 3D Print

My first (mostly) successful 3D print! It is a speaker case for a small speaker I upcycled from a Hallmark greeting card. I intend to use this for my Physical Computing class.

Here's how I made it! First, I measured the speaker dimensions with digital calipers and sketched my idea on paper.

Instructable Storyboards and Ira Glass

Laser-cut Box Instructable

For our video project we will make an instructable video on making a laser cut box. The video has a few stages:

  1. Sketch box on paper
  2. Design box using makercase.com and Adobe Illustrator
  3. Purchase materials from Canal Plastics
  4. Laser cut acrylic
  5. Assemble parts with acrylic cement

Note we've already cleared this with ITP Shop Staff. We make sure our video is factually accurate and properly observes shop rules.

We made some storyboards to clarify our thinking.

Typography and Expression

This week we learned about typography and how font choices contribute to our design decisions. Fonts and typography contribute much to how well information is communicated to others.

I wanted to learn more about Adobe Illustrator so I went through some tutorials to get a basic understanding of the application, then dove into these assignments.

Expressive Words

Our first assignment is to create expressive words. Expressive words are representations of words that convey the meaning of the word through the fonts used to display the word.

Using a thesaurus for ideas, I picked the word opaque. The word is displayed in a bold black font with its antonyms layered behind it in semi-transparent colors.

Input and Output Experiments and Weekly Readings

Electronics Lab

Our assignment for this week was to create something using digital or analog inputs and outputs. The circuit I created will light up a 3-color LED with a new randomly selected color when a button is pressed.

Here is a photo of the completed device:

And a schematic of the circuit:

/images/itp/pcomp/week3/random_color_picker_bb.jpg

The Arduino uses digital input to detect when the button is pressed and released. It picks random RGB values and outputs analog values to light up the 3 color LED in that color. Observe I am using the 3 resistor values I calibrated for last week's assignment to make the LED's 3 colors balance out.

Things That Fit Together

This week we learned new tools for constructing 3D objects. Our assignment is to use what we learned to build something with two parts that fit together.

My idea for this assignment was to build a phillips-head screw. I had a real screw that I used to model my Rhino screw. I began by making careful observations of the screw with a magnifying glass because I wanted the threads, curvature, and proportions to be as realistic as possible. I used digital calipers to take measurements that I incorporated into my design sketch.

It took a lot of experimentation to figure out how to do this. I settled on an approach using Rhino's Taper and Helix commands. After tapering a helix shaped line, I can then use that line with the Sweep1 command to make the threads. It is important to taper before adding the threads because the Taper command distorts the threads in an unrealistic way.

Tisch Soundwalk and The Machine Stops

Tisch Stairwell Soundwalk

Our class project was to create a Soundwalk within the Tisch building. I worked in a group with my fellow students Chian Huang and Ella Chung.

Our idea was to record the audio of ourselves walking from the main entrance of Tisch up all 12 flights of stairs to the top of the building. We added sound effects to our recording that were inspired by the departments or activities of each floor.

To go on this soundwalk, enter the Tisch building located at 721 Broadway in New York City. Present your ID to the guard and walk to the stairs to the right of the elevator. Go through the door and walk up all the steps.

Signage and Information Systems

This week's topic is signage and information systems. Our assignment was to find examples of well designed signage and analyze what it is that makes it effective, and to find examples of poorly designed signage.

My first thought of poor signage is in Brooklyn Bridge Park. I live in the area and do volunteering there on a regular basis. In the park there is a path running through the entire area that is open to bicycles and pedestrians. Here is an example:

/images/itp/visual_language/week2/bbp.png

There is a mixture of people and bicycles everywhere. It's hard to notice the tiny blue sign in the middle that instructs bicyclists to stay on one side of the path and pedestrians on the other side. There are only a couple of signs like this anywhere along this mile-long path. This is an accident waiting to happen.
