Intro: Egg Carton Light
Having never played with LED's before, I've been wanting to find something to make using them. After reading about the Egg Bot Challenge, this crazy idea popped into my head.
I know everyone has moments when they just wish they had a light where there isn't one. So for all those folks out there that just haven't gotten around to changing out the burnt out fridge light bulb, I present the Egg Carton Light.
Step 1: Materials
Single LED flashlight
Step 2: Hollow the Egg
Use the long needle to make a small hole on the small end of the egg. Works best if you twist the needle whilst puncturing the egg.
Make a larger hole on the fat end of the egg (make it big enough to fit the LED inside. Poke the needle inside and kinda swing it around in there to break the yoke and mix things up a bit.
Blow through the small hole to push the egg out of the larger hole. Once the egg is out you can run a little water into the large hole to clean out the egg. (At this point you are free to make a 1 egg omelet or otherwise)
Step 3: Light Source
Dismantle the flashlight. You'll need the battery pack, the LED, and the spring/metal in the bottom of the flashlight.
Step 4: Assembly
Cut out a space in the egg carton to fit the battery pack.
Connect the red wire coming off of the LED (the one I accidentally pulled off) to the positive post of the battery pack
Connect the other wire to the spring and piece of metal that came out of the bottom of the flashlight.
Test fit this contraption in the egg carton, so the LED rests on the bottom of one hole. I setup the spring end on top of one of the "hills" in the carton. The metal arm has been trimmed and bent to fit, and touches the negative post of the battery pack.
When the carton is closed it causes the spring to depress sliding the metal arm down and off of the negative battery post, thus opening the circuit and turning off the light.
Step 5: Finished Product
Here's the finished product.
I added the top half of a plastic egg to cover the battery.
