Paper circuits w/ copper tape
You can quickly create circuits on paper using copper tape, clear tape, and some simple electronics. The image above is from a workshop Jie taught at the Exploratorium museum. Components (available from Digi-Key): Other tools & materials: small binder clipsclear tapecard stock paperscissors or an xacto knife and cutting mattweezerssoldering iron + solder (optional) Getting started You can use the templates we’ve created to guide your initial explorations. Electrical connections Electrical connections between the LEDs, switches, and battery are made with copper tape (shown in grey in the templates). Battery connection To secure the battery and create electrical connections between it and the copper tape, fold a corner of the page over and clip it around the battery using a binder clip or a paper clip: LED connection Surface mount LEDs, shown as yellow rectangles on the templates, are teeny tiny and can be challenging to work with at first, but aren’t bad once you get the hang of it.
