A 8x8x8 LED Voxel Display designed, built and programmed by me.

Responsibilities

Designing and building the display hardware and control logic around an Arduino Micro

• Multiplexed adressing of the LED matrix in eight 8x8 layers

Creating driver software

• An API that handles updating the displayed image

• A wireframe rendering API using the using the DDA rasterized line drawing algorithm modified to rasterize lines in three dimensions

Implementing a demo slideshow displaying simple wireframe models using the driver software

The full HoloVox display.

The LEDs are airbrushed white in order to diffuse them.

The hole in the front is the access to the micro USB port of the Arduino for power an programming.

Control Logic inisde the wooden base of the HoloVox.

On the left are the connectors to the LED cube. On the right are the two boards controlling the display.

The top board holds the Arduino Micro, an 8-bit shift register for going through the layers of the display and resistors for the LEDS. The rest of the board and the second board holds AND gates used to control each LED seperately.
