Samsung Made a Bitcoin Mining Rig Out of 40 Old Galaxy S5s (vice.com)

An anonymous reader quotes a report from Motherboard: Samsung is starting a new "Upcycling" initiative that is designed to turn old smartphones and turn them into something brand new. Behold, for example, this bitcoin mining rig, made out of 40 old Galaxy S5 devices, which runs on a new operating system Samsung has developed for its upcycling initiative. Samsung premiered this rig, and a bunch of other cool uses for old phones, at its recent developer's conference in San Francisco. Upcycling involves repurposing old devices instead of breaking them down for parts of reselling them. The people at Samsung's C-Lab -- an engineering team dedicated to creative projects -- showed off old Galaxy phones and assorted tablets stripped of Android software and repurposed into a variety of different objects. The team hooked 40 old Galaxy S5's together to make a bitcoin mining rig, repurposed an old Galaxy tablet into a ubuntu-powered laptop, used a Galaxy S3 to monitor a fishtank, and programed an old phone with facial recognition software to guard the entrance of a house in the form of an owl. Samsung declined to answer specific questions about the bitcoin mining rig, but an information sheet at the developer's conference noted that eight galaxy S5 devices can mine at a greater power efficiency than a standard desktop computer (not that too many people are mining bitcoin on their desktops these days).

That mean's a single ASIC (Antminer s7) can mine 19 times more a day than every samsung galaxy s5 in existence today.
