<p>My friends Max (<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#104;&#117;&#116;&#97;&#116;&#116;&#101;&#100;&#111;&#110;&#109;&#121;&#97;&#114;&#109;&#64;&#109;&#101;&#46;&#99;&#111;&#109;">&#104;&#117;&#116;&#97;&#116;&#116;&#101;&#100;&#111;&#110;&#109;&#121;&#97;&#114;&#109;&#64;&#109;&#101;&#46;&#99;&#111;&#109;</a>) 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!</p>

<h2>Hardware</h2>
<p>An AtMega32 controls 8 8bit Latches. These 64 bits control, via a PNP Transistor, the anodes of 8 LEDs, each.</p>
<p>There are also 8 N-Channel MOSFETs connected to the AtMega32. They each control the cathodes of 64 LEDs on a Y-Plane.</p>
<p>It can talk to a PC via USB with a FT232RL. A 1Mbit FRAM is accessed over TWI (or I2C).</p>
<p>There's also an AtMega8 which acts as a TWI Slave and sends audio data to the AtMega32. This data comes from a MSGEQ7.</p>
<p>An extensive part list can be found in the Github repository, in Hardware, called parts.txt.</p>

<a href="/img/cube12.jpg"><img alt="Foto 4" src="/img/cube12_small.jpg" /></a></p>
<h2>Software</h2>
<p>The software is composed of 3 parts. The CubeFirmware for the AtMega32, the AudioFirmware for the AtMega8 and CubeControl, the PC software.</p>
<h3>CubeFirmware</h3>
<p>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.</p>
<p><a href="/img/kuehler1.jpg"><img alt="Foto 7" src="/img/kuehler1_small.jpg" /></a>
<a href="/img/kuehler2.jpg"><img alt="Foto 8" src="/img/kuehler2_small.jpg" /></a></p>
<h3>AudioFirmware</h3>
<p>It gets data from the MSGEQ7 and sends it via TWI.</p>
<h3>CubeControl</h3>
<p>Depends on <a href="http://www.oracle.com/technetwork/java/javase/tech/index-jsp-138252.html">Java3D</a>. 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.</p>

<h3>Hardware Emulator</h3>
<p>Allows you to test CubeControl without a real Cube. Unix only!</p>
<h3>UploadTest</h3>
<p>Small CLI tool to send testdata or stored animations from CubeControl. Unix only!</p>
