absolutely amazing! how did you manage to connect so many usb cables to one computer.... and how are you controlling them?

Thanks!

I had 21 4-port USB hubs that I daisy chained together to reduce it to 1 USB going into the computer. I then used Processing combined with a custom c /java wrapper written by a co-worker to talk to the Powermates. Each knob was identified by an index number and could send left and right turn events, press left and press right turn events, and push events. Processing could send back a number from 0 to 255 to control the brightness of the LED.

However, the library no longer works. It needs to be rewritten as it has stopped working with the intel chip Macs. One day I will get back to it. But I am in no hurry to tackle the tangled cord situation.

that looks expensive, but very cool.

Didnt cost a cent. :P

insane..

Cool.

i prefer this sort of thing in the physical world as opposed to the screen stuff. awesome.

it reminds me of a project of mine some years ago: vimeo.com/clip:198646

So this was the project you mentioned at Sciarc the other day. Noisy indeed. Great talk by the way. It really helped hearing your process.

Great effect !

Awesome!
