LED Organizer/Book Light

Introduction: LED Organizer/Book Light

About: I make a lot of things and add my own twists to everyday objects. I would rather make something on my own than buy it. ofton times I save money that way!

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 @ https://www.instructables.com/id/Cardboard-Component-Storage/. 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 (https://www.instructables.com/id/Swich-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

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:

Note: yhis instructable can be modified to accomadate anything froma a buzzer to a motor. Heck, you could probably even add som esort od MP3 player or something. Also you can put this into a hollow book, on a door frame, or even under a plate as a presure senser! The posabilitys are endless.

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

    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
