I have limited knowledge of Max/MSP/Jitter. I took a course that I barely passed!

But, I finally have a project that I'd like to pursue. Although, I don't know on the scale of things how hard this will be. So, can you point me in the right direction? Let me know if what I am wanting to create is super hard, or pretty simple? Is this too much for a beginner in MaxMSP/Jitter?

I want to take a video, and output it into a grid of LED lights. The LED lights would become the pixels of the video. This could be in color, or b&w. I could have just 72 x 72 lights, or thousands of them. The resolution would be different... of course. The more pixels, the higher the resolution.

I found a thing called a Peggy Board. Is this a good place to start? I'm open to experimenting, but want to know I am in the right ballpark.

For example, eventually, I'd like to not be limited by Peggy. I'd like to string lights in a room, and the room would become the video screen... But maybe Peggy is a great way to learn about the video signal to LED's?

Actually, I'm fairly new to Max/MSP and this seems within my scope. I hope I'm not steering you wrong, being very new to this as well, but I would try using an Arduino and play with multiplexing through maxuino. Sounds like fun. As far as the patch, just lower the input resolution down to the resolution of your LED matrix (I forgot exactly what to use, it's in one of the jit tutorials), then I would use jit.scissors to separate the different pixels and test them with jit.op to see whether the pass or fail a threshold value. Then output through maxuino after doing whatever multiplexing formula you have to do, and bingo? At least, that's where I'd start.

not exactly what you are looking for, but maybe it will be useful. I did this little example patch for another thread a while back... it's a javascript that loads a movie, downsamples it, and send out bangs when a cell crosses a certain threshold.

ups, upload didn't work. here is the patch:

Did you manage to get anywhere with using Max with the Peggy 2? I'm using the Peggy 2 with Processing at the moment but would like to use Max for audio processing to control LEDs. Would be great to hear if you managed this with Max.
