  1. Hi

    so I think that if the projects gets funded i ll use MIDIBox platform linked to vvvv with OSC/MIDI, I ve reduced the number of total outputs (for mental sanity purposes) to 352, each will drive a final stage of 48v at 20W, I know that makes a total of 147 Amperes, I am planning to buy half a dozen of Power supplies so that I can split the lines evenly.

    Lights: I d go for Halogen 12v light (group of 4 serially connected) but that fraction of second it takes to get to full brightness and back to off is a serious bummer, LEDs would be better but I need something that can spread the light rather evenly around.

    For the final stage I am probably going to re-use an already working system I used a couple of years ago: 2n3055 and a basic transistor to trigger the final stage. Is it possible to use a matrix system for the final stage too, or am I supposed to use one stage for each output?

    About modulating the power of the output will I be able to do it with PWM avoiding using Analog OutPuts?

  2. Hola Jefe!

    tx for the offer, at the moment what "worries" me is what s the best solution for the final stage hardware wise, 1000 2W drivers is a lot of components.. I would probably go for some already built hardware if the price is reasonable..

    it s not a problem for 16x 8x8 led matrices but it could be for the final stage.. dunno..

  3. You thought you got rid of me! Not so easy boys...

    So today I woke up and decided I want to drive 1000 1W bright leds, what do you think ? It would be digital On/Off triggering and my software platform of choice would be http://vvvv.org . Seems like a huge task, and I d probably go for some already built hardware driver, any idea? How do you see otherwise the idea of building a 1000 digital outputs with MIDIBox ? Anybody tried something similar?

    So how s everybody doing ?

    Cheers from Tenerife!

  4. I think that "natural disaster" stands for the level of organization of the society and the employment scene here in the islands...

    So UPS made it to my front door, now you would expect a dark brown van with a guy looking like Jim Carrey (o maybe Tom Hanks, all in all we are in island in the middle of the ocean), anyway, the guy came with a hippy-like old Renault van and looked more like the local dealer then an UPS employee. He s got my parcel but no money to change.. I sent him back to where ever he came from.. now I understand the meaning of "natural disaster" ...

  5. mm so I ve ordered some components from Mouser.. have a look at the first line, where it says STA CRUZ DE TENERIFE (that s where I live...) sounds scary...

  6. Hi

    the place is in La Orotava, Canary Islands (Spanish territory but a few hundreds kms off the Morocco' coast) and it is a gallery called Aperitivos Visuales, the exhibition is part of a festival named NumaCircuit, www.numacircuit.es

    The projections are programmed with vvvv (vvvv.org) on a 3Ghz PIV and an nvidia 6600gt, plus a wiimote.

    I hope I ll have some more detailed videos soon.

  7. Hi there

    so I friend passed by and I wanted to show him all the leds and bells of the most unused MB6582 on the face of planet heart, so i plugged the dusty thing in and ... no LCD happy welcome.. may I be a victim of the infamous OLED chicken waving voodoo...

  8. ... I see wide agreement here.. I think these days things can change really quickly so I may have to point out that I haven t used Linux for audio for over one year, so my advice "may" be outdated, yet I reckon the CCRMA packages/mailing list being very solid and decently updated. Being Linux the modular beast it is, a distro can be better than another also depending on the way you use it and your needs.
