The colour changing LED projects against a white cut out of the Aurora against a black background. There are small holes in the background with a white LED in behind to give the appearance of stars. When I was looking at images of the Aurora Borealis on Google a lot of them had trees in the foreground so I added some silhouettes of trees to make it look more authentic.
Step 1: What you will need
- White and black card stock
- Template.pdf (see below)
- One White and one RGB colour changing LEDs
- 3V button cell
- Wire, conductive thread or conductive paint
Step 2: Cut out and fold
- Print out the template on heavy paper or card stock
- Cut out each of the pieces
- For the piece with the trees, trace the template on black card stock and cut out
- Valley fold on the doted lines
Step 3: Prepare night sky
- Find something sharp and poke randomly spaced holes into the black background.
- Bend the legs of your LEDs at the base.
- Poke the legs of the colour changing LED through the black background. It should be in the centre bottom with the light aimed slightly towards the back.
Step 4: Add the Aurora
- Using a glue stick, glue the bottom of the Aurora to the back of the treeline (the LED should be behind it).
- Glue the top of the Aurora to the background.
