Hi folks! Long time no see. During this summer, I read up on LED cubes and decided to design and build one myself. It was an exercise in circuit design and programming, as I had never tried taking on a project as big as this, and I had never worked with microcontrollers or arduinos. I also made a small 4x4x4 prototype to see if it was something I could manage. It was also an exercise in patience! Soldering one layer took about 1.5 hours, and soldering a layer to the cube took about an hour too. I think it was worth it in the end, though. Looks pretty neat in person. the video doesn't do it justice.
I'd love to post the schematics, but I don't have any. It was all in my head, never bothered writing it down! I do have the code however, see the description of the video. It's written in Arduino.
It was fun to make, though. Weeks of "entertainment" ;) It also has the option of plugging a controller to it so I can change the parameters of each effect. Unfortunately I can only have about 7 effects total, since the ET-EASY 168 uses a microcontroller with only 16kB memory.

LED Cubes are really cool. Unfortunately the labor involved in building one can be downright staggering!!! Wish there was a way to mass produce these with something that could be easily pick-n-placed etc....
Anyways, very nice work. I love these things.
I did design one myself awhile back that used a DSP processor to make a very cool 3-D audio spectrum analyzer. That could be another idea you could use.

Ive got a few ideas on how they could be mass-produced... very interestingly designed machines :)

I've been playing with that idea myself. Plugging it to the computer, and letting it do all the computation necessary.

We need a transparent PCB substrate, that way everything can be pick-n-place and just assembled in a modular fashion!
there are polyester resins for encapsulation that anrt as exothermic (as much as epoxy) that are totally transparent. this is totally cool and doable with some effort... what are the dimensions of your 8^3 one? (in inches, not communist metric )
some fiberglass is also nearly transparent, though with multi layers im not sure theyed be useful.
