    img_09451 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 [...]

    dsc00490.jpg Ornos: Prototype 01 Test

    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.

    etekgps5hz-02-m.jpg Etek 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 [...]

    dsc00367.jpg Ornos : 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 [...]

    img_0921.jpg Stabilize : 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 [...]

    picture-4.png Ornos : 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. [...]

    Micromag 3 Axis Micromag 3 Axis

    Here’s some modified code from Sensor Workshop to get heading values in Arduino from the Micromag 3 axis magneto sensor. Next up, accelerometer calculations on the magneto sensor to get tilt compensation on the compass readings.

    img_0696.jpg AGS : Haiku Shake V02

    AGS aka Haiku Shake is a haiku generator. Tilting to the left begins the trickling of the haiku. Each haiku is generated randomly based on 3 haiku forms and a set of preselected words. To generate a new haiku, just shake it.

    img_0439.jpg moMo : 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 )
    -updated code for smoother [...]

    A Haptic Navigational Device A 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 [...]
