MAKERS: Muhammad , Itrat , Muhammad , Muhammad COUNTRY: Pakistan

The L3D Cube (3D LED Cube) is a three-dimensional array of LEDs, of size 8x8x8, that is able to display various animations and graphics with the help of a microprocessor.

The Purpose

The main purpose that the L3D Cube serves is in the entertainment sector. For all intents and purposes, it is actually a high-tech display. Think of it as a three-dimensional display consisting of 512 pixels (or voxels in this case) which can be used to visualise any sort of animation or graphics. The cube has commercial potential due to its advanced and unparalleled design. LEDs present many advantages over incandescent light sources including lower energy consumption, longer life time, improved robustness, smaller size, faster switching, easy installation, friendly environment, and greater reliability.

The Technology

L3D Cube, with the help of some advanced programming, can display a variety of visualisations and animations through the use of multiplexing and serial-in, parallel-out shift registers. The cube has 512 LEDs. Obviously, having a dedicated IO port for each LED would be very impractical. Instead, it relies on the concept of persistence of vision to reduce the complexity of the cubic structure. This amounts to 64 + 8 IO pins. Further multiplexing through a 3x8 decoder and octal D-type flip-flops reduces the pin requirement to just 19. The microcontroller used to drive the cube is TM4C123G by Texas Instruments.

Additional Details

As mentioned before, L3D Cube has immense commercial potential due to its advanced and unparalleled design. It could revolutionise our perspective on how we perceive visuals. As wonderful as it is, the experience can still be enhanced. Following are a few potential features that can be implemented in the near future: ? Synchronisation with music ? Remote access via Bluetooth / WiFi ? Interaction between the cube and an individual
