  Tetherlight

  Tetherlight is a hand held light that perpetually points at its sibling. Two Tetherlights constantly point at each other, guiding one Tetherlight to the other with a beam of light.

  Feedback Playback

  FeedBack PlayBack is an interactive, dynamic film re-editing/viewing system that explores the link between media consumption and physiological arousal.
  This project uses galvanic skin response and pulse rate to create a dynamic film re-editing and veiwing system. The users’ physical state determines the rhythm and length of the cuts and the visceral quality of scenes displayed; [...]

  GSR Reader

  Galvanic skin response readings are simply the measurement of electrical resistance through the body. Two leads are attached to two fingertips. One lead sends current while the other measures the difference. This setup measures GSR every 50 milliseconds. Each reading is graphed, while peaks are highlighted and an average is [...]

  Soft Pneumatic Exoskeleton : Ankle Support

  The ankle support is a low profile sleeve around the foot and a strap at the heel to connect to the air muscle. A shorter 12″ muscle connects the ankle support to the calf. The calf attachment is now constructed out of a single piece of leather with nylon reinforcement at the top [...]

  Air Muscle Connection

  The most common point of failure in all the test have been the connection at the collar around each end of the air muscles. The inflation of the muscle along with the tension force rip through the threads around the collar, so I’ve reinforced those points with rivets with some room to expand.

  Exploded Air Muscle

  This is what happens when you pump compressed air directly into an air muscle without a pressure regulator. Good thing I wasn’t wearing it when it exploded.

  Soft Pneumatic Exoskeleton : V 01 Test

  After the first round of testing, I realized assisting jumping with pneumatics is nearly impossible. The size of the tubes and tank necessary to get a high enough cfm to actuate the air muscles at the speed of jumping seems too large for a lightweight wearable application. So, I’m going to concentrate on [...]

  Same Food Same Poison

  So if the Golden Arches Theory of Conflict Prevention is somewhat true, is it simply the established economic ties between countries that prevent wars? How about the shared experience of eating the same food? Listening to the same music, watching the same movies, speaking the same language, wearing the same clothes? Could a [...]

  With Other

  How can we share our unmitigated desire for sex, eating, and drinking? Drooling, like blushing is often beyond our control. Good food, or just thinking of tasty food can make people drool.
  With Other is an amorphous teledrooling device. It comes in pairs, soft, and shaped like a smooth pebble. [...]

  Soft Pneumatic Suit : Prototype 01

  I finally have a full assembly of all the major components sewn with thick canvas and leather. The small scuba tank provides the air pressure, controlled by an Arduino and solenoid valves. The basic operation of pneumatic muscle works. Air pressure at about 100psi inflates the muscle, creating a contracting motion of about [...]

  Pneumatic Muscle : Solenoid Valve Test

  I finally got the solenoid valve hooked up to an air compressor and and arduino board. Air pressure is regulated at 100 psi. It looks like I’m going to need bigger pipes to get more cfm for faster muscle actuation. The shorter muscle has an over sized braided sleeve, which I thought [...]

  Why should I trust you? Because you sound trustworthy? Smell trustworthy? Look trustworthy? How do we measure trust?
  Trust Vision is a personally biased trust measuring video camera. As each frame is presented, a face or faces within the frame are superimposed with trust ratings based on previous faces that have been rated by the user. [...]

  Urban Computing : Window

  Windows give a frame of reference, crops a view, magnifies a perspective. It filters and blocks. Window is the opening that mediates here from there. I would argue that windows are what give walls meaning. Without windows, there wouldn’t be a notion of “there” since the possibility of something [...]

  Laser Tether : Sketch

  TeleCursing

  Video chat is great, but maybe I don’t want to see your face. Or more likely, I don’t want you to see me sitting at my computer in my underwear. A less intrusive channel of communication, like IM, is often desirable but we lose several modes of expression when we only communicate with text. [...]

  Pneumatic Muscle : Pressure Test

  The first set of home brew pneumatic muscles actually work. There’s no leakage and it looks like it holds well over 60 psi. The tiny air reservoir barely holds enough air for 2 actuations, so it looks likes a small scuba tank or a tiny air compressor is going to be needed. Weight [...]

  Pneumatic Muscles

  Here’s my first set homebrew pneumatic muscles. I’m not sure how strong these are going to be, but it looks promising. The compression fittings aren’t being used the way they were meant to be used, so it’s likely that connection will be the first point of failure when it goes under stress.
  As [...]

  Pneumatic Soft Exoskeleton

  Pneumatic systems are clean, safe, lightweight, and reliable. In a pneumatic electronic hybrid system, electric components simply control the flow of air pressure, removing the burden of weight and kinetic actuation from electrical power to pneumatic power. The advantage is a lightweight low idle power system with high power kinetic impact.
  My initial encounter with pneumatic [...]

  Talking Face to Face

  Talking Face to Face is a networked communication system that detects the position of two users in relation to each other anywhere on the globe. Using a combination of GPS and a compass, the audio output is modified to create the sensation of the voice’s position and proximity to the listener. If Bob is [...]

  Grass Type

  Grass Type is a virtual grass mat. Mouse movements send waves of wind across the grass, erasing the imprinted text which then slowly reappears over time as the wind dies down. (developed with Tim Stutts)

  It seems like the prefered analogy for voltage, current and resistance uses water with pressured tanks, hoses, etc. The waterfall analogy was the easiest for me to understand.
