In one of our earlier instructables, we built an Arduino based Audio Spectrum Visualizer using our bi-color LED Matrix modules for the display. You may check it out at https://www.instructables.com/id/Arduino-based-Bi-color-LED-Matrix-Audio-Spectrum-V/

A few months ago, we designed jolliCube, an 8x8x8 LED cube. We are very encouraged to know quite a few entry level electronics hobbyists has bit the bullet and managed to successfully complete their 8x8x8 jolliCube instead of working on a smaller LED Cube as their first cube. You may find our LED cube project at https://www.instructables.com/id/JolliCube-an-8x8x8-LED-Cube-SPI/

Recently, we stumbled upon a 3D Audio Spectrum on Analyzer on YouTube. We were mesmerized by it.

You may find this YouTube video at https://www.youtube.com/watch?v=Vn39txtVIHc

In this instructable, we will use the electronic circuit we put together from our Arduino based Audio Spectrum Visualizer project to drive our jolliCube re-arranged with the 2 sets of 3D 8x8x4 LED Matrix displays placed side by side to form a 3D Stereo Audio Spectrum Visualizer Display.

To build this project, basic electronics knowledge with electronics component soldering skill and some knowledge on using the Arduino are required.

You may view the following YouTube video to see what we will be building.

Step 1: Building the 3D LED Matrix Displays

To build the 2 sets of 3D LED Matrix displays is to practically build the entire jolliCube up with only some steps omitted.

Follow main Steps 1 to 6 in our instructable for JolliCube - an 8x8x8 LED Cube (SPI) to build the 2 sets of 3D LED Matrix displays but omit steps 5, 7 and 15 at Step 5: Assembly Part 2 - Complete the LED Cube with control circuit if you do not intend to use them to create an 8x8x8 LED cube.

<p>hi guys , </p><p>I really need this wonder . can someone make this for me ? </p><p>actually Im willing it pay more if someone can make this instead : </p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/yYPCe372meM" width="500"></iframe></p><p>all the instrusctions and stuff are available in the description of the video . </p><p>please take my money ! </p><p>email : ddehghani@icloud.com ,</p><p>im from germany btw .</p>
<p>This is their making-of. You could do the same as the guy in the video: build the stuff and ask a nerdy programmer friend to do the rest.</p><p>https://www.youtube.com/watch?v=Vn39txtVIHc</p>
<p>Well done ! fabulous. I admire all your works man. Thanks a lot. I am a PIC fan so ... :) I'm still learning and CHR and you have opened my eyes and my mind. Thanks</p>
<p>Beautiful looking display. But not much spectrum information it seems to display more time duration than spectrum, and the repetitive tinkly music was spectrally limited and frankly annoying to listen to.</p>
<p>It would be even cooler to make it real 3D, instead of lighting up the whole row as a single sampling data.. I suggest to add a few msec time delay and variable in arduino to store each of the row separately, and perhaps the front LEDs would be the real time, and then starting to shift to the rear, giving it real 3D look..</p>
<p>Yeah, I was really hoping that the 3rd dimension would be used for more of a histogram display as well.</p>
<p>Dude that foken awesome man!</p>
<p>very nice</p>
<p>why not use different coloured LEDs as well 2 rows blue 2 green 2 yellow and 2 red or what ever sequence you like </p>
<p>You can probably use the colors to show the amplitude of the given frequency in case its getting too hot.</p>
<p>Ok, Things can always be better, bigger, but I think this is really cool, well done :)</p>
<p>Very cool looking display. The depth appears to be static, perhaps have the depth of the cube be driven by surround sound front to rear levels or the inverse of the other channel. Then it would be true 3D look with varying depth.</p>
variation idea: infinity mirror and single card
<p>Now that would be good &quot;infinity mirror and single card&quot;</p>
<p>This looks nice. But then when I watch the video I see always a full line (4 dots) lighting up. So, where is the point in 3D? To me it looks like 4x2D.</p>
<p>same</p>
