Kit-of-No-Parts I wish I had made one of these. But no, not yet. 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. 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. Battery pouches made from paper, plastic and fabric are quick to make and are a cheap alternative to commercially available options. This coin-cell holder is made using copper tape and a mini cloths peg. 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. Second attempt: Print carved from linoleum.
E-Textile Swatch Exchange YEAR OF INVENTION: 2017CREDITS: BeamDIMENSIONS: 150 x 110 mm With a rectangular piece of carbon non woven, a microcontroller ATtiny85, with two analog inputs and 4 LED’s a device can be made which indicates on which quadrangle of the carbon a droplet of water has been fallen. Over the rectangular piece of carbon non woven a voltage is applied. This swatch is a micro invention more than design. main material: carbon non woven, high resistance type eg Eeonyx 50-70k (i still love the summercamp doggy bag of 2013!) used other materials: linen, aluminum (cheap from the supermarket), copper sheet on adhesive paper (expensive), Kapton adhesive tape, electric wire etc for the circuit, 4 smd LED’s, ATtiny85 The smd LED’s farnell.nl: the simple text was emboridered using a Janome sewing machine. the copper was cut using a Silhouette Portrait for step 20 problem solving: Wire Glue, Electric Paint circuit
Making Fabric to PCB “SnapBricks” As I continue my exploration with e-textiles and fabric based inputs, I ran across a problem when trying to prototype some wearable buttons I had made. I needed a way to connect the conductive fabric to a prototyping board so that I could make it more rigid and “wearable”. I tried soldering the fabric to a small PCB but no matter how low I set my soldering iron the wire would melt in the solder and the connection would break. I set out to find a solution and went on Sparkfun’s website. Here are the steps I took to make my very own “SnapBricks”: First I cut my PCB board to the right size and marks some holes equally spaced out. Using a drill press, cut out holes for the fasteners to go through. It was fairly easy to do since there was so many holes already on the PCB, but make sure you don’t make them too big. Check to makes sure all the fasteners fit snuggly, don’t try and force them in as the PCB might crack. Next I cut the PCB leaving some room at the bottom for making connections.

casting There are a large variety of castable materials with various consistencies, colors and other material properties. The information in this post only covers a selection of such materials that I’ve experimented with myself. Silicones Smooth-on is a great resource for all things castable! >> Brilliant Resin This resin is great for casting transparent coating over electronics! Easycast clear casting epoxy >> Smoothcast 326 A clear hard resin that can be mixed with pigments to give it colour. Smooth-on Ecoflex Ecoflex is a really nice soft, squishy silicone that is easy to mix. Dragonskin Latex While not good for casting voluminous shapes, latex is good for applying to surfaces. Mold Making Mold Star (have not tried yet) Smooth-cast 326 Casting urethane foam prototype in Smooth-cast 326 didn’t go so well.
Thingiverse - Digital Designs for Physical Objects electroplating To start electroplating you will need the following materials and tools: - Voltage rectifier - Copper Sulfate - Copper metal - Conductive paint The difference between electroplating and electroforming is that with electroplating the plated metal is intended to stay on it’s base, whereas with electrofomring the idea is to remove the base and have the metal be a stand-alone piece of its own. Voltage Rectifier Converts AC to DC current. >> The Model 1672 is a Quad Display Triple Output DC Regulated Power Supply that provides one fixed output (5V/ 3A) and two variable outputs (0 – 32V/ 0 – 3A) ratings. >> >> >> Copper Sulfate (acidic, sauer) Used for electroplating.
