Step-by-step guide

 

  1. Put the LED on the end of the tongue depressor, splitting the two legs, one on each side.
     
  2. Use a strip of copper tape to secure one leg of the LED to the tongue depressor.
     
  3. Remove one of the arms from the binder clip and thread the unshielded wire through it.
     
  4. Put the binder clip on the side of the tongue depressor opposite the copper tape and wrap the wire around to the side with the copper tape.  Use the wire to secure the binder clip to the depressor by twisting the wire.
        
  5. Fold down the twisted wire and place a piece of copper tape on top of the twist, securing it to the copper tape below.
     
  6. Place a strip of copper tape on the “+” side of the coin battery.
  7. Attach the copper tape with the battery to the other leg of the LED on the depressor.
  8. Now fold the battery back onto the copper tape so the “-” side of the battery is facing up.
  9. You can use the binder clip arm as an on/off switch.
  10. Optional: Use some masking tape to secure the LED in place on the tip.
