  • A slim USB flash drive
  • A slim potentiometer - just for rotation but not resistant related, probably you can find one in old radio circuit
  • An empty USB type A metal case
  • Some plastic plate
  • Sliver red spray paint - you may change to any color you like
  • A thin leather necklace

Step 3: Design the Heart Shape

Base on the size of the potentiometer and USB flash drive board, draft the heart shape.

  1. Plastic plate
  2. USB
  3. Plastic plate
