This is a rough list of resources needed to build one cup:

  • 1 Thermos mug with detachable inner and outer parts (you can get one at Åhléns)
  • 1 Arduino Nano
  • 5 RGB LEDs
  • 1 nRF radio transmitter (?)
  • 4 transistors
  • board with15x11 pin holes (you might want to make it slightly larger so that you get a nicer board than we did…)
  • 15 680ohm resistors
  • 4 1Mohm resistors
  • 1 small switch
  • 1 9V battery socket
  • 2×15 female pinholes
  • isolated wire
  • Strips of copper or equivalent
  • Paper cup to fit into the thermos mug.
  • …and wire, solder, tools and some other bits and pieces.
