We have all seen movies and TV show where someone opens a treasure chest and the treasure inside is so shiny that the container is glowing as soon as it is opened. I thought that this would make a great effect for Christmas presents. So I made a small treasure chest with a built-in light that turns on when it is opened. The lights are activated by a normally open momentary switch. This is the same kind of switch that controls the light in your refrigerator. It turns on a set of battery powered LED lights.
I also show how to add a sound recorder module so that the chests also plays sound effects when it is opened.

After you put Christmas lights on your tree, your house and your lawn ornaments, you might wonder if there is anything else that you can put lights on. Well, why not put lights on the presents as well. It sounds like a fun idea, but no one wants their present to be tethered to the wall with a power cord. So I figured out an easy way to power a set of lights wirelessly with an inductive charger.
In this project, I teach you how to make a wireless light up Christmas present.
