A process to update the firmware on a Geekcreit® 8x8x8 LED Cube 3D Light Square Blue LED Electronic DIY Kit and get it cycling animations, using a Mac OSX. I got this Geekcreit® 8x8x8 LED Cube 3D Light Square Blue LED Electronic DIY Kit from Banggood ('the kit').

My friends Max (hutattedonmyarm@me.com) and Felix built this single-color 8x8x8 LED Cube with me. On this page, you can get the Software as well as Schematics and the PCB Layout licensed under the GPLv3. Have fun!
Hardware
An AtMega32 controls 8 8bit Latches. These 64 bits control, via a PNP Transistor, the anodes of 8 LEDs, each.
There are also 8 N-Channel MOSFETs connected to the AtMega32. They each control the cathodes of 64 LEDs on a Y-Plane.
It can talk to a PC via USB with a FT232RL. A 1Mbit FRAM is accessed over TWI (or I2C).
There's also an AtMega8 which acts as a TWI Slave and sends audio data to the AtMega32. This data comes from a MSGEQ7.
An extensive part list can be found in the Github repository, in Hardware, called parts.txt.
Frank mailed me and explained that the FRAM is operating outside of it's absolute maximum ratings. It should get 3.3V, not 5V. I'll probably update the board and schematic, soon. It seems to work, regardless.
Kay also mailed me. It seems as if the FRAM used is no longer available, but FM24C04BG is a viable replacement part. It has the same pinout and package, and even supports 5V operation, so the problem Frank encountered has solved itself.
Software

The software is composed of 3 parts. The CubeFirmware for the AtMega32, the AudioFirmware for the AtMega8 and CubeControl, the PC software.
CubeFirmware
It's main work is to load images from the FRAM or the AtMega8 and display it. It also monitors the serial Port and reacts accordingly.
AudioFirmware
It gets data from the MSGEQ7 and sends it via TWI.
CubeControl
Depends on Java3D. It renders a rotatable 3D View of the cube. You can then create animations, load and save them, and upload them to the Cube. It has it's own C Library for Windows and Unix to talk to the serial port.
Hardware Emulator
Allows you to test CubeControl without a real Cube. Unix only!
UploadTest
Small CLI tool to send testdata or stored animations from CubeControl. Unix only!

Frank built this Cube, slightly improved the code and made a Slow-Motion movie. You can see the Multiplexing very nice:
Andrej built this cube and sent an X-Ray photograph that he made at his workplace, manufacturing the Eledus - SCIOX X-Ray inspection device. Thanks!

Believe it or not, [Anred Zynch] had no soldering skills before starting this project! What we’re looking at here is an 8x8x8 LED cube set up as a Space Invaders style game with a Playstation 1 controller.

He was inspired by several other cubes like [Chr's], and the Borg cube by [Das-Labour]. The project makes use of an Arduino Mega 2560 R3 to drive the 512-LED array, and an Arduino Uno to take care of the sound effects during game play. It’s kind of like Space Invaders — but in 3D!
Complexity of building and wiring it aside, [Anred] has provided great instructions and the code for the entire project, so if you’re looking to recreate it or something like it, you can! It’s also entered in an Instructable’s contest right now, so if you like it, we’re sure he’d appreciate the votes.
And showing off the cube’s effects:
Not enough LEDs for you? How about this massive 16x16x16 cube? Too many LEDs? Okay, how about this tiny 3x3x3 cube?
