Firefly Now Available for Rhino 5.0

Hi Everyone,

After a long time coming, the complete Firefly toolkit has finally been upgraded for Rhino 5.0 (both 32-bit and 64-bit versions).  This new release includes an updated C_sawapan_media.dll (many thanks to Panagiotis Michalatos!) as well as a new installer!  

The installer should automatically remove any previous versions, and copy all of the core Firefly Grasshopper Assembly files (as well as any needed dependencies) into the roaming Libraries folder on…

Firefly Kinect 0.0004

I have just released an update for the Firefly Kinect (ver. 0.004).  There had been a small bug in the Kinect Video Stream and Kinect Depth Stream components which has now been corrected.  As before, this build uses the Microsoft Kinect SDK 1.5, which means the components will only work in Rhino 5.0.  For best results, I recommend using Rhino 5.0 32-bit version as the Firefly Kinect components also rely on some of the C_sawapan_media.dll functions which has only been compiled for 32-bit…

New Firefly Build, Website, and more!

I'm really excited to announce the release of several new Firefly endeavors I've been working on over the past few months.  The first is the release of a new Firefly Build (1.0067) which is compatible with the latest version of Grasshopper (0.9.0006).  This release has a lot of new features…

Hi Andy,

i've hooked up a dc motor with an h bridge circuit and i have been able to control the rotation and speed so far through Arduino code. Now i wanted to do the same through Firefly, but it keeps working with the Arduino sketch ignoring the current values i am sending through Firefly, shouldn't the Arduino sketch be overwritten? However that was not the case with servos..

Should i reset the Arduino?

Thank you

Hi andy 

I've been trying to work with OSC lately,but unfortunately i was not able to send data from my ipad to grasshopper although I was able to send some data from grasshopper to ipad. all the port numbers and page numbers and stuff seem to be right. i was wondering if you could help me. thnx in advance

Andy,

FYI, I just hooked up a different type of stepper motor (http://robotics.reefat.com/wp-content/uploads/2008/08/PF35T-48L4.pdf) and the speed is much better.  This must be a hardware issue I'll have to look at.  Sorry for the trouble.

Andy,

I really appreciate the quick response.  My issue here is speed.  I took a look at AccelStepper.h, which mentions that speeds above 1000 steps/sec are unreliable...so just to test it, I tried setting the stepper speed to 1000 on the quadstepper component.  The steppers I'm using are vextas: http://www.interinar.com/vexta-px243m-03aa.html, which have a step angle of .9.  So a speed of 1000 should give me an rps of 2.5, but when I set the quadstepper to a speed of 1000, the actual rps I'm getting is really slow, its more like .2 rps.

Andy,

Thanks again for your help today with the capacitors. I have another question regarding quadsteppers and I'm not sure which forum for Firefly is current.  Is the most recent forum at firefly.squarespace.com?  I had trouble finding a discussion part on the new web site. 

Anyway, I posted a question there about increasing stepper speeds with the Quadstepper driver.  I'm trying to attach a dremel to a reprap to turn it into a router.  The quadstepper works great, but I just need some more juice.  Thanks for any help.

-Erick

Hi Andy,

thank you for your reply. I did have a look at Firefly's Audio components. 

We're trying to move an "arm" similar to the polyline in screenshots, where each member rotates in relation to the members in either side of it. The two end members are fixed at one point. (Thinking in section) a fabric skin is attached to the arms. This skin moves according to the arms' movement behind it. We have an Adruino Uno board connected to grasshopper. 

If sound produced by speakers of laptop is our input data, how will it be input into arduino? Also is it possible for us to divide the frequencies of Piano keys into 3 categories of low, medium and high and have them as the output that moves the structure? If yes how should we do that?

thanks heaps for your explanationGH-Rhino%201.jpgGH-Rhino%202.png2.png

Hi Andy,

I am fairly new to arduino and grasshopper, as well. I'm after a sound responsive vertical surface that moves with the sound frequencies produced from a central source (a piano) in an enclosed space.  So we basically are trying to read a sound input and turn it into the surface's movement parameter.Should we use firefly to input sound?

Thank you

Hi Andy, 

Thank you very much for your helpful explanation!

Hi Andy.
Is current Firefly compatible with the new Arduino UNO? I have been to the recent workshop in London and we were introduced to the new board.
Thank you

Luca
