My Project for the Greenbelt Maker Faire is 90% complete. The physical construction, made simple using velcro to attach everything to small Lexan polycarbonate sheets, is done. I plan to custom make some short network cables but that’s optional. I’ve booted the three OS but I need to configure a common network and install the demo application.
The cluster consists of three pair of $40 computers, the Raspberry Pi 3, the Beagle Bone Black, and the ODroid C2. They sit three to a level above the network and power supply. With 24 cores running between 1.2 and 2.0GHz, this little cluster packs quite a bit of compute power into an unassuming laptop bag.
