A great shield for driving an 8x8x8 LED matrix!
First off, a quick announcement. This Thursday is Thanksgiving. SparkFun offices will be closed Thursday and Friday to give us time to
stuff our faces reflect on the things for which we are thankful. We'll be back up to ludicrous speed on Monday. Today, however, we're going to talk about the Voxel Shield.
The Voxel Shield, developed by Connor Taylor, is an Arduino shield designed to give easy control of an 8x8x8 LED matrix. This shield uses nine shift registers in serial, eight of which act as positive outputs for the LEDs. The last shift register is connected to MOSFETs to act as grounding pins. To connect the LEDs, Connor used a method known Charlieplexing.
The results were pretty great. Connor is in the process of developing a Voxel Shield for commercial use. In the meantime, check out his website to find more information about the project! Great work, Connor!
