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.

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.

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.

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)

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

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