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.


Items to be Used:







Prices:

  • Undershirt $12.33
  • Hoodie: $10.65
  • 2 flexible LED strips $29.98
  • 2 Mini Speakers $2.58
  • Buzzer $5.76
  • 2 Proximity Sensors $9.00 
Current Total: $70.30

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

The Good, The Bad, and The Ugly Instructables Posts

The Good:
Reading Sensors with a Microprocessor

  • The post is well-written and clear.
  • Complete list of parts are included.
  • Along with complete instructions and informational backgrounds, images and diagrams are included to enhance understanding.
  • Post includes information on building the circuits with components, the program, and other ideas that can be tested with this information.
The Bad:
  • The post describes enough information to understand the goal of the project and gives simple instructions, but does not go into much detail.
  • The images of the diagrams are crumpled and not the best quality.
  • Very little is explained, and there are elements of careless grammar.
  • The videos linked in the description do not work, so even more information is missing.
The Ugly:
  • The images give a brief idea of the information, but the post has very little information.
  • Nothing is explained, and while links are provided that can help explain some of the information, their role is not explained.
  • Overall while the idea behind the project can be understood after viewing the post and links, there are too many gaps and a lot of questions are left.
