List of Material

  1. Five different type of woods
  2. Arduino
  3. Temperature sensor
  4. Led Display
  5. USB cable

Designing

Top three designs are all for sides of the coaster. Its 90mm x 15mm and designed to connect with other sides. The bottom one is for a cutout of display.

Prototyping and Programming

The basic system is arduino. Using thermometer to read the current temperature and via led display to show temperature.

Programming

Both temperature sensor and LED display are put in function. So those programs may be reuse.

Assembly

Three different type of woods are used for each sides. I chose those to imitate French flag and Shonan Like taste. Circle design at the top is for coaster. You may put your glass or mug on top of it.

Further improvements

  • More stable base.
  • Better Design
  • Sanding
  • Implementation of air pressure sensor
  • Implementation of speaker
  • Implementation of microphone(like Amazon Echo)
