DIY 8x8x8 RGB LED cube

Index

Build a custom jig

Making an 8x8x8 RGB LED cube from the ground up involves a variety of tasks, therefore I need to build a custom jig in order to maintain the spacing between LEDs while soldering. Figure below shows the design of my jig, it is very unique and modern.

Setup a jig

I made this jig using my CNC laser cutter, the Autocad drawing file (filename: Layer building tool.DWG) is available here.

 

Prepare the LED

The LED cube is arranged into 8 layers of 64 LEDs each, therefore you need 512 RGB LEDs. They are all common anode LEDs.

Prepare the LED

 

Bend the LED leg like this. It will take approximately one minute to make one of this.

Bend the LED

 

Build the First Layer

Aligning and straightening the bare copper wire with two pliers as figure below.

The LEDs will then fit snugly into the holes as shown in figure below.

Solder the anode of the LED to the bare copper wire.

Solder the anode pin of the LED

 

Test the LEDs, make sure all the LEDs are working before continue next step. A current limit resistor is required.

Test the LED

 

Solder the rest of the LED pins  to the bare copper wire which including Red pin, Green pin and Blue pin.

Solder the rest of the LED pins

 

It took about one hour to complete this layer.

Trim away the excess leads. Congratulation! First layer of LED cube is completed!

You need to make seven more of this for a total of eight layers.

Each layer of LED cube

 

Stack the layers

I'm using my CNC laser cutter to make one more tool which helps to stack the layers.

Stack the second layer

Stack until the last layer.

Done! All layers completed!

    hola exelente proyecto una duda que tengo cual se supone que es el led nº1 si miramos en cubo de frente.?????
    creo que podria ser el primero de detras de la derecha ????
    es para poder centrar el con1
    gracias

    This LED cube was made by my friend, he modified the hardware only, leaving the source code untouched.

    Good afternoon. Please tell me how you managed to start the danu version of the cube on the code Kevin Darah, because his code is designed for using the register 74ch595, and you have a completely different register. Have you changed anything in the code to use this register?

    Hi,

    congratulation for this very nice cube !
    Is it possible to share the source code for the arduino board ?

    thanks a lot !

    How the Cathode be provided the ground as in 74595 IC it will give you 5 volt we can use hex invertor to make it 0V so cathode is provided the ground and it will light up how MBI5026 works to provide cathode ground ? Please help me in this regard.

    Hi, anup shehkar
    You can send request to my email [email protected] I only created and design hardware part, the software, the way to blink LED and the arduino is copy from other website. If you really wan the Driverboard you can email me, but the parts on the board I think not much I left.

    hi,
    I am highly impressed with the way you have explained everything about how to make 8x8x8 rbg led cube. I am an arts student and struggling for almost a month that someone can explain this in lay man language that how to make it and how to connect it together .I am really interested in the printed circuit board you have created .Please let me know if I can buy it from you.
