Working with Tulane University students over three days, we fabricated and deployed a 32' x 32' x 9' tall 3D matrix of 875 individually addressable RGB LEDs. The intent was to create a platform for dynamic spatial experimentation: luminous forms that can be generated by a variety of static and dynamic inputs including real-time sensor data, social media inputs like Twitter, and connecting the light matrix directly to CAD (using the Firefly for Grasshopper plug-in) or related programs to simulate a range of forms, patterns and more. Vertical light quills were fabricated and installed in the Gibson Quad at Tulane opposite the School of Architecture.
Location: Tulane University, New Orleans, LA.
Project Team: Jason Kelly Johnson & Rip deLeon
EXPERIMENTAL MODES OF INTERACTION & INPUT
This is a preliminary list of the modes we experimented with using the Luminous Forms installation. Small groups of 5-6 students developed a mini-project that explored one of these unique modes of input combined with a specific light quill arrangement.
1. Live interactions using IR Sensors or other sensors
2. iPad interaction with TouchOSC (to be confirmed)
3. Animated object simulation w/ Rhino (digital storeypole?)
4. Twitter (similar to "tweet 2 form")
5. Kinect Depth Track to create topographies
6. Live webcam input using Grasshopper / Firefly
7. Image to Heightfield (also using Grasshopper)
8. Waveforms or Flocking using Processing
9. Gyroscope input with wireless XBee
1. NeoPixel Digital RGB LED Weatherproof Strip (product link) from Adafruit Industries
2. Arduino Mega microcontroller (product link) from Adafruit Industries
3. Arduino Mega electronics prototyping shield (product link)
4. 18/3 "thermostat" stranded wire (product link) from Home Depot (18 ga, 3 wires)
5. 24/4 "intercom" multi-color solid core wire (product link) from Radioshack
6. 4-wire inline connectors (product link)
7. 1" and 3/4" dia Acrylic tube from ePlastics
8. 1" inner dia. Grey PVC Conduit (product link) from Home Depot
9. 1/2" thick MDF sheets (product link) from Home Depot
10. 30 Amp 5v Power Supply (product link) from Jameco
1. Arduino Software (program electronics with code)
2. Rhino + Grasshopper (graphical algorithm editor)
3. Firefly Plug-in (control Arduino with Grasshopper) video link
4. Others that the workshop participants want to explore
SOME USEFUL LINKS
1. What is an LED?, Soldering basics, electronics tutorials and other basic Arduino links
2. Good books to order: Getting Started with Arduino, Make: Electronics, and others
