Octolively Kit - Blue - Tileable Interactive LEDs
Octolively modules are tileable, digital interactive LED surfaces filled with ultrabright LEDs that respond in complex and gentle ways to stimulus provided by human interaction.
Each Octolively module is 4 X 8 inches (10.16 X 20.32 cm) in size, and features eight huge (10 mm) ultrabright LEDs, spaced along a two-inch grid. Each Octolively module also has eight infrared proximity sensors-- one for every LED --to detect nearby motion, even in total darkness. The modules can be tiled edge-to-edge, seamlessly, in any size or shape of rectangular array. You can cover a full wall, or just make a long strip as narrow as 4 or 8 inches wide.
Octolively modules come pre-programmed with eight different effects that respond to motion and gradually fade back to idle when there is no motion-- ideal for making interactive LED walls, bar tops, and coffee tables. You can switch between the different effects with a button press: Gently fading trails after your motion, a "heat" mode that gets brighter as it detects more motion, simple positive and negative "shadow" effects that light the LEDs-- or darken them --wherever you touch, ripple, sparkle, and a "melting" mode where activated pixels fade only very slowly.
Each Octolively module is controlled by an on-board microcontroller and functions as a self-contained, stand-alone device. You do need to provide power (5 V DC), but no central computer nor complex communication wiring is needed. Because it's self contained, there is no trade-off between array size and performance.
Octolively is a fully open source hardware+software design, designed to be hackable.
