Instruction

  • Take a rectangular foam block

  • Orientate the LED legs so they run down the centre of long side of the block. Place the LED about 1-2cm from one end
  • Wrap a piece of conductive tape over the top of one legs of the LED legs and take it down the front of the block, along the underside and half way up the short side which is the back of the block
  • Wrap a second piece of conductive tape over the top of the second leg of the LED running along the long side and around the corner and halfway down the back of the short side of the block. Make a 1cm gap between the two pieces of tape.
  • Insert the battery holder and battery with one pin in each of the pieces of tape.
  • Cut a piece of 1mm EVA foam into a rectangle to make a cabin.
  • Stick the 1mm foam on the two sides of the long side of the block. Stick it at the end away from the LED
