Step 1: Gather the Materials
150 Ohm Resistor - This value depends on the LEDs you are using, your power supply and what's available at your local store.
Christmas Ornament - Used to form the head of the ghost. I found these at Hobby Lobby, these are opaque to help diffuse the light.
White cloth - Used to cover the ornament to create the ghost.
1/4" square wooden dowels - these are used to create the skeleton of the ghosts. It will hold the LED and the ornament.
Glue. (Yellow wood glue for the dowel, hot glue for the ghost assembly)
Soldering equipment (Soldering iron, solder, helping hands, etc)
Power supply - I'm using an old ATX power supply but you can use whatever you have available.
Some copper wiring.
Knife/Saw - To cut the wooden dowels.
Heat shrink tubing (Optional)
Breadboard for testing the circuit (optional)
Step 2: Assemble the Circuit
Then add the resistor to the anode leg.
Next, add a segment of copper wire to the resistors and another segment of copper wire to the cathode leg.
Finally, heat shrink your soldering to help protect it from the elements.
Step 3: Build the Ghost Skeleton
Then I cut two small segments about 1" long.
Glue these two pieces about 1" down from the end of the dowel on opposite sides of the dowel.
This going to create the neck of the ghost so that the ornament has some place to rest and this will also allow you to position the LED's closer to the middle to help evenly diffues the light to create a more even glow.
Step 4: Add the Circuit to the Skeleton
Place the circuit on the same end of the dowel as the neck as in the previous step and place the wires so that it straddles the dowel and glue the wires to the dowel to hold it in place.
I have bent the two outside LEDs to help spread the light around.
Step 5: Cover the Ornament
I covered the ornament and tied it off with a piece of string and then super glued the string down to hold it together.
Before you cover the ornament you could also paint a face on it so that it will shine through the material.
Step 6: Assemble the Ghost
I tried yellow glue but it wasn't strong enough, so I just used the hot glue.
Connect the power and you're ready to go.
Step 7: Oh the Possibilities
There are so many other possibilities you could create with a photo resistor, ir sensor, solid state controller, 555 timer, different color LEDs, etc.
