Origami LED-Lanterns

Electric circuits don’t necessarily need to be soldered – they can also be folded! The small lanterns charmingly mix electrical engineering with the ancient art of paper folding.

You can have simple lanterns as LED-foldies, but maybe you would prefer a glowing Pikachu or a rabbit with a LED nose? You only need paper, tinfoil, an LED and a coin battery (1.5 V), soldering is not required.

Even more fun: paper circuitry
You can find many projects with electric circuits on paper under the term “paper circuitry”. A good intorduction provides sparkfun: https://learn.sparkfun.com/tutorials/the-great-big-guide-topaper-circuits.

It’s interesting to experiment with other materials as well, i.e. copper bands or even conductive ink, which allows to draw circuits on paper.
