Introduction: LED Halloween Lights
Here is how to make decorative LED Halloween pumpkin lights using LED's, ping pong balls, and some wire.
Step 1: Parts N Tools
You will need:
-5 feet of stranded wire (two wires twisted together)
-10x orange 5mm LEDs
-3 volt battery pack
-2x AA batteries*
-Coin cell for testing
-Hot glue gun
-10x ping pong balls
*Be careful that the AA batteries do not exceed 2.5 amps. This could cause the LEDs to burn out. Test the batteries with the multimeter beforehand. Test the string after ever each LED is soldered with a coin cell.
Step 2: Start Soldering
Step 3: Prep the Ping Pong Balls
Slowly drill 3/16" holes through the writing for the LED's. Stick one all the way in and hold it in with hot glue. Shake out all the extra bits of plastic through the hole before putting the LED in. Draw a pumpkin face on both sides of the ping pong ball with a sharpie. Put tape on te exposed leads.
Step 4: Schematic
All LED's are wired in parallel
Step 5: Hang It Somewhere
The last step would be to hang this somewhere. It could be over a window or door, or even on an umbrella or haunted house.
