Inspired by the work of Arthur Ganson and other kinetic artists, this post features some mechanical gears assembled and sculpted from various materials such as wire and cardboard.

Recipes >> Molded Circuitry

In contrast to casting traces by applying the cast material selectively to a flat surface, molded circuitry is cast into a mold. I’m interested in being able to cast both flexible and firm conductive materials in combination with common casting materials such as silicone and epoxy. This post describes various attempts at creating molds and […]

Recipes >> Paper Power Pouches

Battery pouches made from paper, plastic and fabric are quick to make and are a cheap alternative to commercially available options. Copper tape and conductive fabric work great as conductors and some squishy foam or fabric, or else some flat magnets, help achieve a reliable contact between your pouch conductors and the contacts of your […]

Recipes >> Assembled Coin-cell Holder

This coin-cell holder is made using copper tape and a mini cloths peg. The LED lead wires are soldered to the strips of copper tape on the peg, which simply clips onto a 3V coin-cell to complete the circuit.

Recipes >> Press-fit Battery Holders

Press-fit, also known as interference fit or friction fit, describes a connection that is held without adhesive, screws or nails, but simply by the friction between materials and shapes of either part after they have been pressed together. This recipe describes various ways to make press-fit holders for a range of standard batteries.

Recipes >> Taped Traces

This is one of the quickest techniques for prototyping circuits, as well as an efficient and reliable way of making flat and flexible circuitry. Copper tape and conductive fabric tapes are relatively affordable and comes with or without conductive adhesive. When using copper tape with conductive adhesive, connections between separate pieces of tape can be […]
