Category: Crit 3: Visual

For the Visual Crit, I used Arduino, Rhino, Grasshopper, and GH plug-in Firefly to visualize sensor data over a topographical landscape. The topography model was initially generated digitally with Rhino and Grasshopper, so it could be used later in the model visualization. Contours were exported to 2d CAD to cut the physical model.

The physical model was constructed of lasercut chipboard, with enough variation in height to imitate a landscape that could plausibly have multiple microclimates, which can form due to differences in light, drainage, and airflow. Changes in topography can drive these shifts in environmental conditions. Light sensors will installed in different areas of the model.

Uploaded to the arduino is this Firmata code (which has been edited since the 2015 version to account for some differences in Arduino):

 This Firmata allows you to control an Arduino board from Rhino/Grasshopper/Firefly.
 Updates, Questions, Suggestions visit: http://www.fireflyexperiments.com
 
 1. Plug Arduino boards into your USB port; confirm that your Arduino's green power LED in on
 2. Select your specific Arduino Board and Serial Port (Tools > Board; Tools > Serial Port) *Take note of your Serial Port COM #
 3. Verify (play button) and Upload (upload button) this program to your Arduino, close the Arduino program
 4. then open ... Rhino/Grasshopper/Firefly
 
 Note: The Firefly Firmata sets the following pins to perform these functions:
 
 *****ON STANDARD BOARDS (ie. Uno, Diecimila, Duemilanove, Lillypad, Mini, etc.)*****
 ANALOG IN pins 0-5 are set to return values (from 0 to 1023) for analog sensors
 DIGITAL IN pins 2,4,7 will return 0's or 1's; for 3 potential digital sensors (buttons, switches, on/off, true/false, etc.)
 DIGITAL/ANALOG OUT pins 3,5,6,11 (marked with a ~) can be used to digitalWrite, analogWrite, or Servo.write depending on the input status of that Firefly pin
 DIGITAL OUT pins 8,9,10,12,13 can be used to digitalWrite, Servo.write, or analogWrite depending on the input status of that Firefly pin
 
 *****ON MEGA BOARDS (ie. ATMEGA1280, ATMEGA2560)*****
 ANALOG IN pins 0-15 will return values (from 0 to 1023) for 16 analog sensors 
 DIGITAL IN pins 22-31 will return 0's or 1's; for digital sensors (buttons, switches, on/off, true/false, etc.) 
 DIGITAL/ANALOG OUT pins 2-13 can be used to digitalWrite, analogWrite, or Servo.write depending on the input status of that Firefly pin
 DIGITAL OUT pins 32-53 can be used to digitalWrite, Servo.write, or analogWrite depending on the input status of that Firefly pin
 
 *****ON LEONARDO BOARDS*****
 ANALOG IN pins 0-5 are set to return values (from 0 to 1023) for analog sensors

Next, with Grasshopper/Firefly, the serial data from the light sensors is read. This data is used to generate points, which act as attractors in a domain field. The brighter the light, the smaller the circle illustrated in the domain field.

The final results can be viewed as a plan, or project onto the digital model surface to be viewed in 3d.

Problem:

Many rooms in the basements of buildings are very depressing and hard to work in because of the lack of windows and access to nature. Looking out the window is a very comforting and calming action that one can take for granted when working on floors where there is plenty of access to windows. Not only being able to look out the window and see what the weather is currently, but also being able to see nature outside is very helpful to productivity. In order to solve this problem, this project attempts to make a virtual window that allows you to see the outside environment and also interact with it. The p5.js script reads the weather of the desired location and inputs that into the script which then decides what to do based on what the weather is. For example, if it’s raining outside, the visual feedback will be a rain simulation with the rain droplets accumulating at the bottom to show how much it has actually rained. The same thing happens with snow and other weather events that have a physical element falling to the ground. In addition to the simulation of the weather, the device will have a gyroscope inside reading the current tilt angle and sending that back into the p5 script. With this tilt information, the accumulated physical weather element will then move around the screen to be level with the ground.

The following images and videos show part of the system working with light rain, heavy rain, and snow. The current script is able to read the weather and report back to the user what it is outside. The simulation of the physical weather elements are also able to move around corresponding to the tilt angle accumulating at the bottom until the weather type changes.

The idea for this project comes from an earlier project in this class from someone else involving sensing the weather outside and reporting it to the user. Where this project differs, however, is it will incorporate a visual representation of the weather inside a screen. The general functionality will include sensing the weather either through sensors or getting data from online and then interpreting that into visual representation that can either be displayed through p5.js or an LED screen controlled by a teensy. The two different styles will work the same way just with slightly different implementations.
