Intro: Ukulele LED Light
In this instructable I am going to show you how to create Ukulele LED Light that changes color.
Step 1: Materials
For this instructable you only need a few things.
LED- I used a 10mm RGB self cycling LED. 20-50 Cents. You can take an LED pretty much any old electronic device or buy them online. Radio shack sells them normal (non RGB) LEDs for an arm and a leg.
Coin Cell Battery- I used the CR2032. Very Common. You can get them at radio shack or online. Even Big Grocery Stores have them. They cost any where from 7 cents a piece online to close to $5 dollars at radioshack. Here is one of many stores online with cheap batteries.
Electrical tape- About 5cm. You could even use duct tape.
Magnet- You need at least 2 maybe more depending on size and strength. I would recommend a rare earth magnet. They are really strong, and pretty cheap. You can get them online or cannibalize them out of old toys, hard drive or any number of electronics. They only cost pennies for small ones. ,There are some really big ones that cost a lot though. ($100s of dollars!!),
Magnetic Switch- I used one that I took off of an old sliding door. It was used for a security system. You need the type that is on in the presence of a magnetic field. You can buy these online, at radioshack or at your local hardware store. ( Please Shop local, no big box stores. Big Box stores are evil!!!) They cost about $3.
Ukulele or Guitar- You could use any hollow body guitar or Ukulele. It is probably not a great idea to stick magnets next to your guitar if it has pickups because it could screw it up.
Solder and Soldering Iron- This makes the connection that much better.
Step 2: Assemble
OK, the first step is to attach the Switch to the LED. I clipped the LED down and then soldered the switch to it. Then I Basically make a LED-Throwie. Tape the LED to the battery. Once thats done just push the Throwie though the strings and let it fall inside. Once it is inside slip a piece of tape inside and push it down from the outside attaching the LED to the inside of the Ukulele.
Step 3: Jam!
Now jam away at your hearts content and let the audience enjoy the light show and music.
Hope you enjoy.
