The link below is an example of the modification that I have made to the Sparkfun RGB LED matrix to present visuals on a larger scale: http://www.youtube.com/user/Kianbrill#p ... D-Nbvm_cSA
The following is a link to learn more about the project:

The next link will direct you to my site where you can download an 8 and 4 Channel, custom-spatialized ableton set, max patches for communicating recorded/live video through arduino into the LED matrix and learn more about the construction that went into my projection system:

Re: 8 channel project, Max-arduino- Sparkfun RGB LED code etc
I like your work.
We had considered using vellum over a matrix of cells for our interactive LED board we took to Burning Man; video here: http://www.youtube.com/watch?v=Zu5ORo3Im1g
I think we ultimately determined that vellum might not make it out in the desert, and translucent white plexiglass would have been a bit more expensive.
We got ours working with video also, so it works with cameras and you can create some pretty awesome interactive video feedback with it.
We're currently planning to refine the generative music algorithms it uses, and potentially offload that to a computer, rather than trying to keep it all on the microcontrollers.

That is looking really sharp- thank you for sharing!
Yeah, the plexiglas would be the way to do it, but at 7.5x120ft, that was not looking like a viable option.
For now I am running the vellum with single sheets and it's an interesting effect. Low values create a different quality than more intense colors. It creates an illusion of changing depth that I like. In the end, I may decide not to use an intermediary diffuser (inner or second sheet of vellum- which works, btw) after all.

Re: 8 channel project, Max-arduino- Sparkfun RGB LED code etc
Thanks!
Hahah, yeah, in retrospect using plexiglass would have been a very small percentage of our final cost. But 7.5x120ft definitely is prohibitively expensive. And heavy!
What would an inner sheet do for you? Is the single sheet too transparent?
Are you a student at a Master's in art/video/communication program or something? Or do you do this work for fun/art/profession?

Re: 8 channel project, Max-arduino- Sparkfun RGB LED code etc
The inner sheet diffuses the light so that the outer sheet is a solid, saturated pixel. This was the original goal but it has a different effect and will take one person 2-3 days to do.
I have been working in related tech since around 2004 (there is some stuff on the website) but I am currently a first year MFA student in New Media. This project was going to be the "if I don't go to graduate school I will...", but my advisor liked the idea once I was accepted, so I went for it.

Hey,
My installation in Pittsburgh has been a major success. If you are in the area, please check it out!
There are some pix on my website:

Here is a video of the work:
http://vimeo.com/19011895
It does not do it justice. Hard to present a minimal 8.1 sound system in stereo and the low-level lights are optimized to adjust in human eyes, not cameras.
The piece is rocking. You should check it out if you are near Pittsburgh.

Two more days to check out my installation, if you are in the Pittsburgh area: ibrill.com
And for those who asked for video, I finally got some time lapse shorts that do the visuals justice:

Re: 8 channel project, Max-arduino- Sparkfun RGB LED code etc
How difficult would it be to use this patch/session but with MIDI output instead of arduino? I'd love to try this with my ColorSynths.
Re: 8 channel project, Max-arduino- Sparkfun RGB LED code etc
I am not sure what you are asking. Which patch?
Specifically, which would you want data sent from; sound source? Spatialization engine?
The answer is, probably not a big deal. Currently I have a patch that sends from max to arduino via serial and from max to maxforlive via udp. It's all just data that I scale in one way or another. For instance, all of the data coming into m4l is scaled to either 0-1, or 0-127 before talking to the API.
