MaJaTron is a 3-Dimensional, color graphics display system. It consists of 125 RGB LEDs arranged in a cube of 5x5x5 dimension. Each LED is a multicolor Red, Green and Blue LED and the control circuit of the system can individually control the intensity of each color, thereby, creating a full color, graphics system. Each LED is independently controllable. To control these 125 LEDs, a control circuit consisting of 13 AVR Microcontrollers is used. The AVR device chosen is ATMega32. Each ATMega32 controls 10 LEDs. All the microcontrollers are networked together in a pseudo-RS232 network. This network gets the pixel color and intensity information from a PC. The Mega32s are programmed to operate at a rate of 230400 bps, thereby providing a frame update rate of more than 30 frames per second. The PC runs a custom graphics creation and simulation software, which any user can use to create, simulate and then download the graphics/animation onto the MaJaTron network of LEDs.

 MaJaTron can also be offered as  a DIY kit in near future. Currently, the price of this kit is yet to be decided and will depend upon volumes. If you are interested, send a mail to majatron.cube@gmail.com. You can also specify, what you would be willing to pay for such a kit.
