Make simple or complex electrical circuits on a flat piece of paper!
Using copper tape and surface-mount LEDs allows you to make a fully functional circuit on a flat surface, like a piece of paper. You can make light-up greeting cards, make origami animals come to life, or create three-dimensional pop-up paper sculpture that have working lights in them.
The basic circuit is very simple, and yet allows for a wide range of explorations and aesthetic expression.
With a little more effort, you can add switches, which can be as simple as a piece of aluminum foil, to add a dynamic element to your creation. The window on the little house above lights up when you close the door.
Or you can keep the circuit really simple and let your creativity shine in other ways, like making this beautiful cupcake with light-up sprinkles…
Here is a list of useful parts if you want to experiment with paper circuits at home.
