michael witt: charlieplexing is a kind of multiplexing. hence the name.

It’s not multiplexed, it’s “charlieplexed” look around on instructables, there are some good examples of charlieplexing.

Once it's 8^3 it becomes kind of useful.
ak's last link: http://www.das-labor.org/wiki/Borg3d
and also this one: http://www.jamesclar.com/product/2003/3dcubev3/index.html

With 8^3 you could scroll text messages through the cube.
(not that anyone would be able to read it)

"seriously, what's with the led-matrix obsession? the damn things are almost useless. unless you own a bar and need a scrolling marquee sign to advertise happy hour. but that's so last season,"

you can play pong with it :)

Does any one know where to find the source for something like this? I cant code for my life, but i want to build one of these sooooo badly.

So simple, I’ll have to make a dozen.

I like the smaller ones much more than the thousand voxel units people are showing around. There’s a real diminishing return.

seriously, what’s with the led-matrix obsession? the damn things are almost useless. unless you own a bar and need a scrolling marquee sign to advertise happy hour. but that’s so last season, just like neon.

the first thing i did with a microcontroller was build an 8×8 rgb led matrix. i have no idea why. and now i’m going to have to build one of these. damn you.
