YouTube user Phaxmohdem has built a 15 Raspberry Pi 2 (60 core) supercomputer cluster into a portable toolbox. He is using a 300W power supply for it but it only draws about 45W when under full load. He’s done some benchmarks but hasn’t said what he’s using the cluster for (although the comments section has some suggestions. *rolls eyes*) Watch the video above for a little tour or visit the YouTube video page.
