Fish bag

Making process:

Materials:

  1. Two LED bublbs
  2. Wires
  3. A battery pack with three AAA batteries
  4. Fabric
  5. Needle and thread
  6. Resistor

Story:

I have mild night blindness, therefore I want to have a light helping me walking at night. I choose the fish shape because light reminds me of some types of fish in the deep sea which light up by themselves.

This is my first time sewing and soldering, also choosing fabrics. So I made mistakes in almost every steps – bought not suitable cloth, trimed the cloth in wrong size, forgot buying LEDs, connected bulbs in wrong way, placed LEDs in wrong place. But it’s fun and I learned a lot after every mistake.

Iphone 6 Teardown

The product I chose to tear down is iphone 6 because my eyes just sticked to it when I saw the white cubic package. Everytime I was super excited to get a product from Apple. There’s actually a funny story between me and Iphone. Back to 2012, I was in my first year of middle high school, and visited the US by a study camp. That’s the first time I saw iphone 4 which used by a girl in my team. By contrast, I was using the phone that my mom got for free by charging calls – so jealous. Also, since then, Iphone has become a symbol of technology, design, fashion and wealth. For iphone 6, an interesting finding is that it’s the best selling model among all Iphone. So, let’s go for a look.

Components

The inside of iphone 6 is compact and neat by the well designed layout. Apart from the battery, which takes up half the area, many electronic components are distributed around. They are fixed by brackets and screws, and powered by circuit boards.

When I finished the disassembly, I was shocked by Apple’s exquisite design and precise manufacturing. All the parts are easy to disassemble, which means more convenient repair and recycling. Also, this is the first time I take a close look at the elecronic components whose function has been used by me every day. Just list some of them below.

  • Back camera
  • Front camera
  • Logic board
  • Front: components related to frequency signals
  • Back: components related to storage, Wi-Fi, touch screen control etc
  • Speaker
  • Home button
  • Lithium-ion battery: surprisingly foud that the battery is soft. After research, it is because Apple use the soft packaging technic. Soft-pack lithium batteries are liquid lithium-ion batteries covered with a polymer shell. The structure is packaged with aluminum-plastic film. It is safer because when a safety hazard happens, the soft-pack battery will only bulge and crack and won’t explode. Besides, it’s ligther and has more capacity.
