The idea here is simple. Stick an LED and 3V 2032 battery into a paper cube orgami thingee.
Great idea, well executed.
This little LED-lit cube is much more than just a paper lantern: It’s a translucent and flexible thin-film electronic circuit that hooks up a battery to an LED, limber enough to be folded into an origami box. And the coolest thing about circuits like these? You can make them at home.
