LED Cube RGB 4x4x4

Intro

This LED Cube RGB 4x4x4 is actually based on Charliecube designed by Asher Glick, which all the informations are available at https://aglick.com/charliecube.html

What I made here is a PCB version, which all the circuitry were made into 2 separated boards, which then will be connected using headers. And these are the 2 boards.

The left one is for LED Pillars. And the right one is for the controller board.

Making

First thing to start when making this LED Cube is to prepare the LED. At this project, we will use the RGB LED, with Common Cathode type.

And using a jig, we will bend the LED's legs to our need.

As you can see at the picture above, I left the Cathode leg half bend, to differentiate it from the others. This will come handy when we want to solder it to the wire.
The target is to make the LED like picture below

And below is the led pillar soldering process. As seen below, the Cathode position of each LED (the one without loop) is rotated clockwise for each LED.

And for another tips, after soldering to the wire, I will cut the 3 wires that connected to Anode (R G B) of the last (bottom) LED, shorter. And left the wire that connected to the last LED's Cathode the only one longer. This will become our position marker when placing it into the PCB.

And here are the circuit boards with all the LED Pillars soldered, and the controller board assembled with all the components.

And here is the picture of the LED Cube RGB 4x4x4 in complete form.

As references, here are the schematic of the 2 boards above.
