Picture of LED Organizer/Book Light

This instructable will show you how to make a LED light for a book/laptop/organizer. It turns on when you open it and off when you close it. I came up with this out of pure nececity. I do allmost all of my electronics from my costom cardboard organizer ( thanks =SMART= ) If you want one, get it @ Well I needed a light for it so I got to instructable-ing.
 This, my brain baby, is now here to help you if you have the same problem I had.


Step 1: The Circut

This is a very simple circut. it is basicly a glorified version of my Switch throwie ( All it is is a few LEDs connected Annode to Annode, Cathode to Cathode atatched to a switch and a battery via two long wires.

Step 2: What You Need

Picture of What You Need

You need:
3 LEDs
Battery (I used CR2032)
Lever Switch
Electrical Tape
A Book/Laptop/Organizer to put the thing on

Step 3: Building It

The process to make this is very simple and will take about 5-10 min. to make. First you tape (or solder) a piece of wire to your switch. Second you tape (or solder) the wire to the NEGATIVE (-) end of the battery. Next you get your 3 LEDs and twist the annodes together and twist the cathodes together and then you tape (or solder) a long piece of wire to the cathodes. Run that wire down to the battery and tape (or solder) it to the POSITIVE (+) end of the battery. Do the same with the Annodes and the other end of the switch.

Step 4: Making It Look Beter. (Optional)

If you want to you can put tape onto the wires to "Hide" them. I used Electrical tape because it was the only thing I had.

Step 5: Test It

Open it. It will light up. Close it. It will Stop shining. If it works you did it right. Please rate or comment.  Hope you enjoy!


Step 6: Note:

How does this work? Does the lid of the box hit the switch?

So it's a N/C switch (normally closed)?

It depends on how it's wire. If it is hooked up to the first and third terminals, like I have done here, It will be a normally open switch. If you hook it up to first - second or second - third, It will be normally closed
