Instruction

  • A rectangular foam block
  • Take the two legs of an LED and split them apart until the LED will sit flat on a foam block.
  • Orientate the LED legs so they run down the centre of the long side of the block
  • Wrap a piece of conductive tape over the top of one legs of the LED legs and take it half way around the block.
  • Wrap a second piece of conductive tape over the top of the second leg of the LED and around the back of the block but leave a 1cm gap to the other piece of tape on the bottom of the block
  • Wrap the material around the block and use a band to collect it at the end of the block
  • Insert the battery holder and battery with one pin in each of the pieces of tape.
  • Cut a hole so the light can come through
  • Cut a hole under the bottom of the block so that the battery carrier can be accessed
  • Make a fin out of bubble wrap and glue it along the top of the long block on top of the LED

Problem Solving

  • The bubble wrap needs to sit over the LED to get the best diffusion
  • If the LED does not work check all of the connections
