High-Low Tech
How to engage diverse audiences in creating their own technology by situating computation in new contexts and building tools to democratize engineering.
The High-Low Tech group integrates high and low technological materials, processes, and cultures. Our primary aim is to engage diverse audiences in designing and building their own technologies by situating computation in new cultural and material contexts, and by developing tools that democratize engineering. We believe that the future of technology will be largely determined by end-users who will design, build, and hack their own devices, and our goal is to inspire, shape, support, and study these communities. To this end, we explore the intersection of computation, physical materials, manufacturing processes, traditional crafts, and design.

Research Projects

  • Animated Vines

    Leah Buechley, Jie Qi and Adrian Melia

    Animated Vines is an interactive paper installation that comes to life in the presence of a viewer. Normally a static wall hanging, as the viewer approaches the vines begin to curl and slither up and down. Each vine is made up of eight units, and each unit actuated to curl using muscle wire sewn directly to the paper. While a single unit can only curl slightly, cascading the units sums the individual movements to create a lifelike dance. The muscle wires’ movements are silent so that the interaction is accompanied only by the sound of gently crackling and creaking paper.

  • Circuit Sketchbook

    Leah Buechley and Jie Qi

    The Circuit Sketchbook is a primer on creating expressive electronics using paper-based circuits. Inside are explanations of useful components with example circuits, as well as methods for crafting DIY switches and sensors from paper. There are also circuit templates for building functional electronics directly on the pages of the book.

  • Codeable Objects

    Jennifer Jacobs and Leah Buechley

    Codeable Objects is a library for Processing that allows people to design and build objects using geometry and programing. Geometric computation offers a host of powerful design techniques, but its use is limited to individuals with a significant amount of programming experience or access to complex design software. In contrast, Codeable objects allows a range of people, including novice coders, designers and artists to rapidly design, customize and construct an artifact using geometric computation and digital fabrication. The programming methods provided by the library allow the user to program a wide range of structures and designs with simple code and geometry. When the user compiles their code, the software outputs tool paths based on their specifications, which can be used in conjunction with digital fabrication tools to build their object.

  • Computational Textiles Curriculum

    Leah Buechley and Kanjun Qiu

    The Computational Textiles Curriculum is a collection of projects that leverages the creativity and beauty inherent in e-textiles to create an introductory computer-science curriculum for middle- and high-school students. The curriculum is taught through a sequence of hands-on project explorations of increasing difficulty, with each new project introducing new concepts in computer science, ranging from basic control flow and abstraction to more complex ideas such as networking, data processing, and algorithms. Additionally, the curriculum introduces unique methods of working with the LilyPad Arduino, creating non-traditional projects such as a game controller, a networked fabric piano, an activity monitor, or a gesture recognition glove. The projects are validated, calibrated, and evaluated through a series of workshops with middle- and high-school youth in the Boston area.

  • DIY Cellphone

    David A. Mellis and Leah Buechley

    An exploration into the possibilities for individual construction and customization of the most ubiquitous of electronic devices, the cellphone. By creating and sharing open-source designs for the phone's circuit board and case, we hope to encourage a proliferation of personalized and diverse mobile phones. Freed from the constraints of mass production, we plan to explore diverse materials, shapes, and functions. We hope that the project will help us explore and expand the limits of do-it-yourself (DIY) practice. How close can a homemade project come to the design of a cutting-edge device? What are the economics of building a high-tech device in small quantities? Which parts are even available to individual consumers? What's required for people to customize and build their own devices?

  • Exploring Artisanal Technology

    Leah Buechley, Sam Jacoby and David A. Mellis

    We are exploring the methods by which traditional artisans construct new electronic technologies using contextually novel materials and processes, incorporating wood, textiles, reclaimed and recycled products, as well as conventional circuitry. Such artisanal technologies often address different needs, and are radically different in form and function than conventionally designed and produced products.

  • Getting Hands-On with Soft Circuits

    Leah Buechley and Emily Marie Lovell

    Getting Hands-On with Soft Circuits is a set of instructional materials which seeks to expose middle and high school students to the creative, expressive, and computationally engaging domain of e-textiles. Engaging in hands-on activities, such as creating soft, electronic textile (e-textile) circuits, is one promising path to building self-efficacy and scientific understanding – both of which can have a dramatic impact on diversity in the field of computing. The instructional materials include a workshop activity guide and an accompanying kit of low-cost craft and electronic components.

  • LilyPad Arduino

    Leah Buechley
    The LilyPad Arduino is a set of tools that empowers people to build soft, flexible, fabric-based computers. A set of sewable electronic modules enables users to blend textile craft, electrical engineering, and programming in surprising, beautiful, and novel ways. A series of workshops that employed the LilyPad have demonstrated that tools such as these, which introduce engineering from new perspectives, are capable of involving unusual and diverse groups in technology development. Ongoing research will explore how the LilyPad and similar devices can engage under-represented groups in engineering, change popular assumptions about the look and feel of technology, and spark hybrid communities that combine rich crafting traditions with high-tech materials and processes.
  • LilyPond

    Emily Lovell, Leah Buechley, Kanjun Qiu and Linda Delafuente

    LilyPond is a budding e-textile Web community that fosters creative collaboration through the sharing of personal projects. Home to a growing repository of skill- and project-based tutorials, LilyPond provides support for young adults who want to design and create soft, interactive circuits with the LilyPad Arduino toolkit.

  • LilyTiny

    Leah Buechley and Emily Marie Lovell

    The LilyTiny is a small sewable breakout board for ATtiny85 microcontrollers–devices which may be integrated into circuits to enable pre-determined interactions such as lights that flash or areas that can sense touch. The circuit board can be pre-loaded with a program, enabling students to incorporate dynamic behaviors into e-textile projects without having to know how to program microcontrollers.

  • Novel Architecture

    Leah Buechley, Jie Qi and Adrian Melia

    This project is an experiment in material and scale: a life-sized pop-up book that you can open up and step into, made using only cardboard, an X-acto knife, tape, and glue. Inside the book is a kinetic mural of breathing pleated flowers. As you tug on a string of beads leading from one flower, the rest come to life, moving like puppets using a series of strings attached to motors. The mural itself is drawn using conductive fabric and copper tape, which serve as both expressive and functioning traces within the circuit. Electronic components are also openly displayed and emphasized to explain the electronic workings behind the mural.

  • Open Source Consumer Electronics

    David A. Mellis and Leah Buechley

    We offer case studies in the ways that digital fabrication allows us to treat the designs of products as a kind of source code: files that can be freely shared, modified, and produced. In particular, the case studies combine traditional electronic circuit boards and components (a mature digital fabrication process) with laser-cut or 3D printed materials. They demonstrate numerous possibilities for individual customizations both pre- and post-fabrication, as well as a variety of potential production and distribution processes and scales.

  • Piezo Powered Tambourine

    Jie Qi

    An electric tambourine that is completely powered by the playing of the instrument. The jingles of the tambourine are lined with piezoelectric elements, which generate voltage when impacted. This voltage is then harvested to turn on LED lights on the tambourine. The harder the tambourine rattles, the greater the voltage generated by the piezoelectric elements and thus the brighter the light. Yellow LED lights on the jingles light up when the corresponding piezo is rattled. If the tambourine is played with enough force, blue and red LED lights on the band also light up. Thus, the player can both hear and see the music generated by this instrument.

  • Programmable Paintings

    Leah Buechley and Jie Qi

    Programmable Paintings are a series of artworks that use electronic elements such as LED lights and microphone sensors as "pigments" in paintings. The goal is to blend traditional elements of painting–color, texture, composition–with these electronic components to create a new genre of time-based and interactive art.

  • Self-Folding Origami Paper

    Leah Buechley and Jie Qi

    A first-step toward origami robotics, I/O paper is a pair of origami papers in which the red (controller) paper senses how it is being folded and the white (output) paper follows. When the white paper is flipped over, blintz folding allows the paper to get up, wobble around, and even flip itself over. The microcontroller and circuitry is on the body of the red paper and the white paper is actuated by shape memory alloy.
