7x7x7 LED cube driven by Arduino mega

7x7x7 LED cube driven by Arduino mega

The cube is able to process 142 frames per second, that is, 1 frame every 7 milliseconds. Within this time period, it loops through a still frame 7 times (Each cycle of POV lasts 144 microseconds). This is able to compensate for flickering during video recording, allowing all camera’s to record fluid video without distortion. The cube itself is controlled with an Arduino Mega 2560. For each frame in memory, the Arduino reads and bit shifts 49 bytes of data for an encoded duration. This allows for the cube to be applied to a variety of purposes, from text display to effects to music visualisation. The frames were generated through complex Processing scripts, allowing for a multitude of operations such as shifting in any direction (seen in the rain effect), and an edge shift (seen in the scrolling text around the outside of the cube). These scripts were used to perform the b...
