Firefly Experiments

Firefly offers a set of comprehensive software tools dedicated to bridging the gap between Grasshopper (a free plug-in for Rhino) and the Arduino micro-controller. It allows near real-time data flow between the digital and physical worlds – enabling the possibility to explore virtual and physical prototypes with unprecedented fluidity.

As a generative modeling tool, Grasshopper offers a fluid visual interface for creating sophisticated parametric models, but by default, it lacks the ability to communicate with hardware devices such as programmable microcontrollers or haptic interfaces. Firefly fills this void. It is an extension to the Grasshopper’s parametric interface; combining a specialized set of components with a novel communication protocol (called the Firefly Firmata or Firmware) which together enable real-time communication between hardware devices and the parametric plug-in for Rhino.

A notable distinction for Firefly is that it is the first visual microcontroller programming environment designed specifically for a 3-D parametric CAD package (such as Rhino). This feature means that real-world data, acquired from various types of sensors or other input devices (video cameras, internet feeds, or mobile phone devices, etc.) can be used to explicitly define parametric relationships within a Grasshopper model. Firefly completes the communication feedback loop by allowing users the ability to send information from Grasshopper back to the microcontroller in order to incite specific actuations (ie. lights, motors, valves, etc). Ultimately, this workflow creates a new way to create interactive prototypes.

as far as I could understand about azteeg, its a sort of combination of Arduino and ramp according to reprapwiki. you might wanna find the firmware to upload on your board maybe in github or websites like reprapwiki itself. Moreover for building 3dprinters you need Stepper motors instead of servo, Cause servo motors have a limited angle to rotate usually 180 degree but steppers are unlimited and have different accuracy like 1.8 degree and variety of voltages,amps, torque and stuff like that. Furthermore Steppers are known with their steps and how many steps they need to turn 360 degree which is called a revolution, for example for 1.8 accuracy it needs 200 steps to rotate a complete circle. I am in the same process and I'm building my own 3d printer, but i use Ramp1.4 and arduino mega but not with Firefly. I hope I could help although a little.

hello 
I am currently new in firefly and I am tring to connect an azteeg board (creat for 3d printer) to firefly but I have some trouble to find the way to find and conect the good pin the firefly plug in seems to be design to work with arduino uno board or mega how can I conect my azteeg x1 board to firefly and send some information to the sevro motor, activate the fan or controle the power of the heat of the hot end with the sensor. if you have somes clue or you now some other works feel free to respond.

thanks for this great plug-in

Origami - grasshopper + arduino

Comment by Guido Maciocci on May 5, 2014 at 1:33am

Andy, some progress... 

I found your question on the Leap dev forums which pretty much outlined the same problem. 

So now, i moved the relevant .dll's to the same folder as the python script i'm running in Rhino Python. 

I use clr.addreference to add the LeapCSharp.NET3.5.dll and append the \\leap\\lib folder to sys.path to reference the libraries. 

Now i can add a controller, and a listener no problem. As soon as I try to poll a frame....rhino crashes!

Hi Andy, 

I have a particular question related to the Leap Motion controller and its intergration with Rhino Python rather than a question specific to Firefly (sorry, but i don't know where else to post this). 

I am writing some python scripts based on the leap API to certain things in Rhino using the controller. As proof of concept scripts they are currently working outside of Rhino and I would like to begin integrating them via Rhino Python and Rhinocommon. 

My problem is that I am unable to get Rhino Python to speak to the controller, in that i keep receiving the following error:

"The type initializer for 'Leap.LeapPINVOKE' threw an exception"

Now, as far as I have managed to research, this error is usually related to the referencing of the wrong type of Leap libraries (x86 or x64). 

I have copied the Leap SDK .dll's into the same folder as the script I am trying to run. I have also included LeapCSharp.NET4.0.DLL, Leap.py and Leap.pyc. 


The only way i can get the Leap module to load is by adding a clr.AddReferenceToFileAndPath pointing to LeapCSharp.NET4.0.dll assembly and appending the leap\lib forlder to sys.path. 


The Leap module imports but I get the PINVOKE error regardless of the x86 or x64 libraries I include in the folder. 

I managed ONCE to import the module and run the leap Sample.py script but I can't remember how I did this. Also, when it ran, it did not print any Leap data to the console and Rhino tended to crash on running the script. 

Would you or anyone else have any advice to point me in the right direction?

Thank you so much for your help, 

Guido

thanks andy, finally I bought a Arduino starter Kit with UNO, if everithing goes fine, then level up ;)

Comment by Andy Payne on April 2, 2014 at 8:40pm

Hi Jorge,

As far as I know, it should be compatible with Firefly... but I haven't run specific tests on it.  However, my understanding of the RedBoard is that it is almost identical to the Uno (and/or Duemilanove) both of which work just fine with Grasshopper.

HTH,
Andy

is firefly Compatible with SparkFun RedBoard???????????????????

Thanks Simon!

Feedback time (sorry for my poor english)

Firefly is awesome, everything works just great...

For example the UDP reciever... I stream whatever for a data from my android phone and it works brilliantly. With gHowl just took ages and still not working. Kinect function are perfect. Really, a world with made out of stuff like Friefly would be a world wher I would be happy to live!

Arduino is working perfectely, in all ways.

I hope one day we will get full resolution for cameras (kinect, webcam or whatever)

Keep doing what you are doing, it's brilliant

Simon
