Tcho, created by the founders of Wired magazine, is probably the nerdiest chocolate operation in the country. And, it so happens, the only bean-to-bar manufacturer in San Francisco. The Feast gave us a peak at their factory a couple of months ago, teasing that it could be controlled via iPhone.
Well, this is how Tcho's iPhone-controlled factory works. It allows surprisingly fine-grained control over the lab from anywhere - the melangers (mixers), the roasters, cameras to check on things, even the lights. [The Feast]
