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.

Stack the layers

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

Stack until the last layer.

Done! All layers completed!

    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.
