Upcoming Events

Jason Kelly Johnson will be running a one-day intensive Firefly/Arduino Workshop "RESPONSIVE BUILDING FACADES" on July 27, 2012 in San Francisco (as a part of the Architect's Newspaper "Art and Science of Building Facades" Symposium.) Register here.

*Read Jason's Hardware Recommendations blog post for 2012-13 Firefly Workshops.  

Are you teaching or participating in a workshop that is using Firefly?  Let us know about it and we'll feature it here on the Firefly website! (info@fireflyexperiments.com)


Delta Bot Print Head Test

The Delta Bot Print Head Test by Brian Harms

A quick glimpse of the definition behind the mechanics, a preview of the digital delta bot, and finally the physical delta bot working in unison with it's digital counterpart.

For more information, check out Brian's Blog.


First Delta Bot Test

The First Delta Bot Test by Brian Harms

Fairly successful first Delta Bot run. No smoothing yet, and the servo mounts are all but stable, so I have high hopes for the robot-mounted version.

For more information, check out Brian's Blog.


A_FAB Robot in Action

The A_FAB Robot in Action by Brian Harms

First documented operation of the A_FAB robot. It sits idle, stands, walks, changes the position of its end effector, and extrudes a material in specific patterns.  A prototype for a robot capable of creating brand new built environments for itself on a print bed potentially unlimited in size.

Kinetic Pavilion

The Kinetic Pavilion by Elise Elsacker and Yannick Bontinkx

This project orients itself on the development of a new kind of pavilion that’s capable of acting upon changing weather conditions, human movement or human moods/mindsets. It’s shape has been made dependable of ecological choices and parameters extracted from the pavilion’s surroundings. Just like every other organism, this new prototype changes itself when parameters take on other values. - text provided by authors.  For more information, make sure to check out their website.

How it works:

1. Input: Ipad, Ecotect, Processing (sine function, webcam, twitterfeeds,…)

2. Process:
a) input parameters are sent through OSCTouch , gHowl, geco GH2Ecotect and UPD to Grasshopper.
b) Different kinds of data are translated into height coordinates.
c) These processed coordinates are sent through Firefly to an Arduino-board

3. Output:
a) Arduino controls 28 servos
b) Spur gears translate these coordinates into a vertical movement, controlling the roof structure.


Firefly Linkage System

I came across this video on youtube posted by member dobac09 and really loved its use of physical interaction and linkage systems.  He has a number of other videos that use Firefly as a virtual prototyping platform for his physical model.


Nintendo DS Touchscreen with Firefly

This was a very quick demo I made to test a touchscreen from a Nintendo DS game console.  In this video, I use the touchscreen data to send information into Grasshopper via the Generic Serial Read component.  Using the Data Log component (with the wrap input set to true) I can track the last 20 values and plot them on an XZ plane.


Firefly Intro plus Flex (Bend) Sensors Laminated into Composite Panel

In this Intro to Firefly video, there are several examples including one featuring 4 flex (bend) sensors embedded into a laminated composite panel.  Each of these sensor values can be read into Grasshopper (in real-time) and can be used to control a virtual simulation of the same bending stresses.


Controlling a Pan/Tilt Servo Setup with Firefly

In this video, we are using two numeric sliders in Grasshopper to control a pan/tilt servo setup.  In this case, one slider controls the panning servo, while the other controls the tilting servo.  The setup seen above can be purchased from Trossen Robotics (some assembly required).


Using Wii Nunchuck to Control Grasshopper via Firefly

The video above demonstrates how to use the Wii-Nunchuck component in Firefly to control a parametric model in Grasshopper.  I'll be the first to admit that this is not a 'new' demo... In fact, this demo was heavily inspired (in concept) by this video that was created in 2008 that shows how a Wii nunchuck can control a mechanical arm in 3D Studio Max . 

Unless you feel like cracking open the end of your Wii-Nunchuck to get access to the different wires, I recommend buying this $4 adapter developed by Tod E. Kurt.  You can buy them at any of the links below (some assembly may be required).
