Book of Light

About a year ago I made a gift inspired from an instructable I had read. This instructable detailed how to make a book that lights up with a warm glow when it's opened. Here are the instructions.

I really liked the idea, but there were some areas I wanted to change or improve.
For one, I didn't use batteries in the book. This was to avoid having to either change or recharge batteries. To me this meant the book could be used more freely because there weren't any battery anxiety. Instead of batteries I opted for an USB cable so the book could get power from any old phone charger. The USB cable I ordered was extendable. I chose extendable so the cable could be rolled together and neatly tucked away when the book wasn't powered.
    Another change I did was to use regular 5 mm LEDs. Regular size LEDs are much easier to acquire and they don't develop as much heat. Heat was a big concern to me because all the electronics would be enclosed in old and dry paper. Opting for regular LEDs instead of high wattage LEDs had another positive effect. The book could be made with several more light sources, which meant the light from the book would be spread more evenly.

And by the way! The book was made as a gift and I'm happy to report it was a huge success. Appreciation always makes the effort worth it.
