The Library of Missing Parts is an ongoing and ever-expanding effort to represent real-world phenomena in a symbolic language compatible with the flow of electricity.

The field of electronics sorely lacks symbolic representations for some of the most relevant parts of any electronic circuit. These missing parts include humans, animals, nature and the built environment – including all objects and artifacts that make up the everyday reality of our lives and the circuits that inhabit it.

This lack of common symbols to represent the full spectrum of inter-dependencies in which each electronic circuit is embedded has lead electrical engineering to develop an extremely narrow perspective. As a result, the electronic devices in our lives are becoming less and less nuanced, more and more bland.

The ohmHook is made from a crochet hook mounted on a circuitboard including a microcontroller which measures the electrical resistance between the crochet hook and a crocodile clip connected to the opposite end of the tool handle. The resistance is displayed as the 10 bit reading of the microcontroller’s analog-to-digital converter.

Having the ability to sense electrical propeties of a material as you are manipulating it can allow you to explore it’s potential for creating electronics. Highly conductive materials make good connectors between physically distant electronic parts. Materials with stable electrical resistance can be used to detect location of contact on their surface. Materials with varirable resistance often respond to forces such as stretch, pressure, bend and twist with a change in resistance, and can be used to sense a large variety of physical interactions.
The ohmHook does not have to be used for crochet. Use it to probe and explore all kinds of materials, and to invent new ways of building electronics.

Prototypes:

A vibrating resistance meter for crochet – this crochet hook translates electrical resistance into vibration, making electrical resistance a tangible property of an E-Textile making process. The Ohm Hook allows you to develop an electrical sense for the materials you work with. For example, if you are crocheting stainless steel yarn to make a stretch sensor you can tailor your design to the range of resistance you want because you immediate feedback on the resistance of what you are making.

The ohmHook is made by cutting and stacking pieces of clear acrylic, and sewing them together with thick thread. The circuitry is contained within the layers of the acrylic and remains visible. To use as few elements as possible, I sought to use materials for both their electrical and material/mechanical/aesthetic properties. For example, the shaft of the crochet hook is itself the negative lead to the coin-cell battery.

MAKE TOOLS, NOT PARTS

The ohmHook is part of a series of tools for e-textile techniques that are motivated by a desire for MORE tools and LESS parts when it comes to building electronics. So many electronic functions are compartmentalized into discrete parts. These parts make up the tool-set of most engineers/designers/makers who build electronics. And while they make it easy and fast to prototype and build electronics, these parts also end up defining and constraining how we make and what we can build. By making tools that allow us to create our own parts, I hope to encourage a greater electronic diversity.

Tools for E-Textile Techniques

A set of tools designed to support a variety of E-Textile techniques such as sewing, knitting and crocheting with conductive threads and yarns. As ambassadors of process, and storytellers of trade, tools have much to say of how we create the things we make. By imagining, creating and using tools designed specifically for the interdisciplinary practice of Electronic Textiles, it should be possible to tell new stories about a new trade.

Seam Ripping Continuity Meter

This seam-ripper has a continuity meter built in. An LED lights up to indicate when an unwanted electrical connection is made between the tip of the seam-ripper and the part of the circuit that you wish to disconnect from. An alligator clip can be connected to different parts of the circuit, so that you can decide where to measure for unwanted continuity. The LED is powered by a 3V coin cell battery. The brighter the light, the less electrical resistance.

Vibrating Crochet Hook (Continuity Meter)

This vibrating crochet hook can be used to measure the resistance of a crochet stretch sensor while it is being made. Continuity and resistance can be measured while the sensor is being crocheted. The vibration motor is powered by a 3V coin cell battery. The less resistance, the stronger the crochet needle will vibrate.

Breadboard Pincushion

This pincushion design has strips of conductive fabric adhered to its surface, so that metal pins or component contacts that protrude through the same piece of conductive fabric are electrically connected. This cushion can be used for prototyping electrical circuits as well as for string pins, needles and components.

A WEARABLE STUDIO PRACTICE WEBSITE

Now is a perfect time for electrical engineers to become mobile with their practice. It’s not just electronic parts that have become smaller and smaller, but also many of the tools used in electrical engineering (power supply, multimeter, oscilloscope, programmers… ) have become more compact and portable. Many practices closely related to hardware such as software/programming and CAD/design have been liberated from static infrastructures because laptop computers – their primary tools – are powerful and lightweight. Co-working spaces and FabLabs offer temporary workspaces all over the world. There is an awareness of the benefits of local production and site-specific development.

Wearable Studio Collection

A collection of wearable and portable accessories that allow the electronic textile engineer to travel, build hardware on-site, incorporate local craft techniques and resources, experience different cultures, encounter and collaborate with other disciplines and share their skills with others.

The items in this Wearable Studio Collection are in various stages of development, but shall eventually be documented in great detail, so that they can be reproduced by others. I hope to encourage copies, modifications and improvements to these designs.

2014

The content of this website is the outcome of a collaboration between Irene Posch & Ebru Kurbak (Stitching Worlds) and Mika Satomi & Hannah Perner-Wilson (KOBAKANT). Starting in November 2014 and continuing indefinitely. The collaboration is motivated by a joint practice in electronic textiles (or textile electronics) and the desire to try and imagine, design and build functional tools for ourselves.
