05.05.09Counting to a Billion
As a child, I remember challenging myself to count to 1000, 1 million, or 1 billion. I don’t think I ever made it. Why do we aimlessly count? How long would it take to count to a billion? Counting to a Billion is a device created to fulfill the desire to count. The electronics consists […]

04.13.08GSR 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 calculated to smooth out the […]

03.27.08Ornos: Prototype 02
Here’s the first test with Ornos. The compass readings are behaving pretty well considering it’s right underneath a spinning hard drive. The 1.2Ghz processor and 512 RAM don’t seem to be enough to download and render the image quickly enough, so I’m going to have to figure out how to speed things up.

03.13.08Etek EB-85A GPS Example Code
Here’s some example Arduino code for getting a Etek EB-85A module up and reading latitude and longitude (will probably work with most GPS modules). You can purchase a module from Sparkfun. The module only needs power, ground, rx and tx. Most modules like the Etek start sending NMEA strings as soon as it has power. […]

03.12.08Ornos : Prototype 01
I was going to cover the lasercut masonite with a leather sleeve, but I’m going to go with cnc milled RenShape with a painted finish for the next prototype. The compass needs to be calibrated to the offsets caused by the magnetized computer hardware and I need to tweak some code to get the frames […]

02.25.08Stabilize : Accelerometer + 4 Servo Motors
So far, the Arduino reads the x and y tilt values and translates them into motion across 4 servos to maintain a horizontal platform at the top. Next, I need to get the z tilt values to reverse the x and y tilts, so you can tilt the whole thing up side down and still […]

02.24.08Ornos : A View from Above
Since the first hand drawn maps of the stars to satellite imagery and GPS navigation today, our frame of reference and our perception of space has been molded into a view from above. Our understanding of place is often linked to an abstract representation on a map rather than a physical relational comprehension. You could […]

11.19.07moMo : version 2
-new compass unit calcuates true north in relation to itself and waypoint (so it points in the right direction even if you spin it) -upgraded to 32 Channel!! ETek GPS module -4 AA batteries powers the entire circuit with 5.6V at 2700mha -a new skeleton ( to be outfitted with a flexible skin soon ) […]

10.03.07A Haptic Navigational Device
A haptic navigational device requires only the sense of touch to guide a user. No maps, no text, no arrows, no lights. HND sits on the palm of one’s hand and leans, vibrates and gravitates towards a preset location. Imagine an egg sitting on the palm of your hand, obeying its own gravitational force at […]
