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.
