An Arduino set up with the monome serial protocol, running with MonomeSerial and several of the MaxMSP patches from the monome base collection.

As always, apologies for the video quality: hopefully you can occasionally make out what's happening on screen!

i love it :D i've been following your project for awhile and look forward to building one myself. im not sure if want to use digital pots, or an led dimmer. also you mentioned the brightness/multiplex problems. shouldn't the led's be able to handle higher pulsed current which would correct some of the dimming?

love your work i expect some more details :D

here are some of the chips im looking at:

search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=296-17732-5-ND
16 output w/ pwm and dot correction, 4096 steps

search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=568-1039-5-ND
cheaper but not dip, 16 output with pwm registers, 256 steps.

dr unsped: First of all, this version isn't using any digital pots at all; it's just connected to the blue channels in an all-or-none fashion.

On the RGB version higher pulsed current would partially solve the brightness problem, but not completely. Part of the problem is that the digital pots have resistance even when set to zero. That limits the maximum current I can get at 5V, so I couldn't pulse much higher without using an external power supply.

I have several of the TLC5940 chips and they're great! That's what I'm planning on using in version 2, if I ever get around to making it.

Fascinating stuff.

Despite my sub-amateur level knowledge of electronics, your series prompted me to take a look at arduino which looks like an excellent platform.

Would you mind posting the arduino code you use here to interface with the monome protocol?
