Week Seven Experience Documentation

Reflection
  • The critique for our Noise Project occurred on Monday. 
    • Specific information about the project is located in the Noise Project post.
  • We were going to continue learning about programming, but class on Wednesday was cancelled for hurricane Michael.

Noise Project

Description and Methods

          While my original design was that of a power strip, I instead decided to use a ceramic pumpkin as my interface, since the power strip was proving to be too difficult. I decided to use a pumpkin because I still wanted my base idea to be about the artistry of everyday objects, and since it was now October the object was relevant to the season. While creating the interface, I was attempting to convey the idea of an object that would be bought as a toy. I began by repainting the pumpkin before addressing the touch points.


          The touch points were made using Aluminum foil, and were placed in the eyes, nose, and side mouth locations, while the middle three holes of the mouth were for the speaker. Because I was having issues getting the touch points on the circuit board to work, I soldered all of the wires to the board first. I removed the LM386 chip from its mounted piece each time I soldered a touch point, since I seemed to keep short circuiting the chip. When I finished two wires, I would place the chip back into the seat and test the touch points.
          After soldering all of the touch points, I used electrical tape to connect the wires to the aluminum foil, which I then secured inside the pumpkin with electrical tape. Similarly, the chip and speaker were placed inside with electrical tape.

Critique and Thoughts

          While I understood that the aluminum foil might not have been satisfactory, I chose to use it at the time because I was running out of options. When working on the project, a lot of time was lost trying to get the touch points to work properly. Then, when I continuously kept running into problems with the power strip idea, I did my best to create another interface plan. However, I received some ideas from the critique given regarding the current state of the design. If I am to redo the project, I will make the touch points in different areas, such as possibly placing leaves and vines around the pumpkin, and having certain areas be touchable. I will probably try to have the pumpkin itself raised off of whatever surface it was placed on, since the noise seemed to be louder when I allowed the speaker to play through the bottom of the pumpkin. Similarly, I will do more research regarding how to make the project more stable, as well as how to create a more commercial toy appearance.

Regarding the video, for the final I will be sure to have better documentation. At the time, the only person I had available was not good at recording, so I made do at the time.

Week Six Experience Documentation

Reflection
  • The critique date for our Noise Project was changed to next week, so I continued working on my project.
    • Due to different issues, I changed my idea from a power strip to a ceramic pumpkin interface. 
    • Thomas helped me re-solder my circuit board design, since I short circuited the LM386 chip. This time, a mount piece for the chip was soldered to the board instead so that if I had issues I could simply replace the chip. 
  • We were to begin programming the Arduino, but a certain driver was missing from the school's computers, causing the lesson to be moved to next week.
    • We did, however, end up creating a short program that changed the speed of the LED flash on the Arduino board.

What Sensor Do You Want To Use?

          While I am not sure which sensor I will pick yet, I am thinking about using either infrared sensors or proximity sensors, since I will most likely be designing a project that reacts according to the distance of objects.

Project Proposal

Inspiration:

  • I received a lot of inspiration from Instructables, specifically from the project Proximity Hat. In this design, the author used a proximity sensor to avoid hitting objects. I really liked the idea of layering two hats in order to keep the object wearable with a separation between the electronics.
  • I was also vaguely considering ideas from the Anti-Rape Lingerie design we were introduced to in the beginning of the class.

Design:

  • I decided to make a hoodie that utilizes proximity sensors to react when people get close to me.
  • When within distance, red and blue LEDs will alternate, reminiscent of police lights. Similarly, noise from a buzzer will be activated through speakers.
  • The original basis was that if an attacker got close, the hoodie would hopefully spook the attacker, or at least make enough noise to attract attention. However, the general idea can be expanded to spooking anyone that tries to get close when you're just not in the mood to be close to people.

Week Five Experience Documentation

Reflection
  • As a class we were introduced to Instructables, an online site used to learn how to make things and contribute to a community of knowledge.
    • The process of finding new things is easy.
    • There are competitions for creating good projects and posts.
    • There are some really interesting projects, and a wide variety in all subjects.
  • We were given an assignment to examine good, bad, and ugly posts to get an idea of good formatting and practice.
  • We were briefed on the final project.
    • We were told that we will post our project and findings on Instructables at the end.
    • We were told that we will be using some sort of sensor in our project, so we should browse to get an idea of what kind of sensors are available.
  • We learned how to use a multimeter.
    • We learned how to measure voltage, amps, and ohms.
    • We learned how to check if materials are conductive and how to check whether links exist in the circuit (such as what the power connects to in the circuit.)
  • I worked on my final project.
    • Finally soldered circuit board, but while the touch points worked at first, they stopped making sound so will have to speak with Thomas before continuing.
  • Sensor Research.
    • Examined the Boe Bot project that uses sensors that differentiate between black and white lines.
    • Read a post that mentioned temperature reading sensors.
      • The post also gives ideas such as programming objects to illuminate when certain events are triggered.
    • Short reading on types of sensors. The reading discussed:
      • IR Sensors
      • Ultrasonic Sensors
      • Touch Sensors
      • Proximity Sensors
      • Pressure Sensors
      • Level Sensors
      • Smoke and Gas Sensors
