HW 3: Paper circuits


reflection eassy
Designing:
1. learn to fold paper to connect the circuit; the AL stript cannot be cut into parts.
2. First three simple circuits just follow the tutorial.
3. Button circuit has a button part, and I design as another paper which has a vertical circuit stick on one side of button part. When you press down the paper, the circuit will connect.
Blink circuit is the same way, but putting 3 same vertical circuit on the button, when you pull the button, the light will blink.
4. pull circuit needs a pull tag. I cut a line between the circuit and make a pull tag which fits the line. Then making three horizontal circuit. When you pull the tag, and the circuit will connect.
Calculating:
1. Battery capacity: 80 maph
2. one LED current: 10 ma
3. every circuit except 2nd one I have 1 LED, so battery life is Battery capacity/ Current = 8h, the second circuit I have 2 LEDs, so battery life= 4h
Soldering:
Soldering is more difficult to do on my own than looking at other people doing that. At first, I found it pretty easy to just melt and solder on the circuit. However, when I began soldering, I found the material could not be easily melt because of the wrong position. It should be at the flat part of head. Then I found the LED could not fix firmly when I started to solder. I soldered, the LED moved.
From this soldering experience, I learn I need to take everything seriously, because everything is not as easy as it looks.
My First Career Fair altlab
The first impression that left on me was that the career fair was so formal and big that I did not even know where to go. As soon as I got in the second floor, I felt like I was swimming in the human pound, filled with lines of people waiting to talk to the employers. Because I could only stay there for approximately 40 minutes, I only queued in one short line and got to talk with a woman employer who looked friendly. As far as I said I was a freshman, she suddenly turned off her bright eyes. She generally explained what their company was and said they were possibly finding some students who were sophomores or juniors or higher. I was disappointed because I felt embarrassed when talking to her, I did not know what to say further.
Overall, it's not a bad experience, and that broaden my horizon, making me confident when attending the next fair.


Introductory Project: TECHONOPOLY
Our project is to design a technical monopoly: technopoly. Basing all the pieces around the theme, we would be able to design a creative game that would allow us to incorporate all the needed components. The various squares on a monopoly board would allow us multiple opportunities to integrate interactive electronic components, and through our design of the game and the components we would be able to creatively construct our game.
The game board is laser cut and is colorless save for several integrated LED’s to allow a simplistic yet engaging design. Within the top of the game board it was designed so that small laser-cut slits would allow the wires and tape to assimilate into the top of the board. This design permitted the electrical components to function without the distraction visible connections and batteries. All connections were to be within the box as well as the batteries powering the circuits. Due to issues with the laser cutter, this plan failed, and improvisation was necessary to complete the project.


While working on our project, we ran into several challenges which we were forced to overcome. The biggest challenge we faced was the laser cutter not working which in turn forced us to reassess how we would complete several key aspects of our projects. We ultimately printed many of the components out on paper, including the game board and the chance and community chest cards. This left our finished product not as polished as it would have been, but it also created further issues which we had to address. The design called for holes being cut into the game board which would allow us to store all of our circuits and other electronic components underneath.
Design Project
Our project is called EcoClaw.The EcoClaw is a different take on a normal trash picker. On the handle of the EcoClaw is an OLED screen that displays the amount of trash you’ve picked up and the different materials of each. On the grips of the claw is an inductive sensor on one side and a capacitive sensor on the other, which will detect the material of the trash the EcoClaw picks up. Inside the EcoClaw will be the wiring, which will connect the OLED screen and the sensors to a Flora or an FTDI, that our team will code to reflect what the sensors pick up onto the counter on the screen.

Our process and how we make it
We have a detailed instruction in instructables. com. Here is the link
