8x8x8 LED cube project

Chris shared his latest LED cube project details. This is an 8x8x8 LED cube soldered using 512 single color LEDs. We’ve seen much bigger LED cubes even with RGB LEDs. But these are result of patience and hard work. If you are thinking about building one 8x8x8 is a good starting point.

Such Led cube can be easily controlled using Arduino which is used here. Obviously in order to address individual LEDs there is additional electronics required. In this case Chris used one addrees selector 74HC138 and eight data buffers 74HC574. Also Arduino switches LED cathodes of each layer using transistors. This is enough to address individual LEDs. By switching single layers of cube pretty fast it gives illusion of normal display. Led cube is placed on box where all electronics is hidden and serves as solid stand. So this is nice weekend project.
