Depending on your taste for social interaction and tolerance for distraction, an open floor plan or “bullpen” office might not be so bad with a total of four people. Hackaday.io user [fiddlythings] likes it, but people often stop by to see him or one of his coworkers only to find them busy or absent. While their status is something they could plainly see in Microsoft Communicator from their own desk, some people like to chat in person or stop by on their way to and from meetings.
In order to save these visitors a few seconds, [fiddlythings] came up with an IM status indicator using their existing nameplates outside the door. Each of their names has a little silver dot by it which he backlit with a flattish RGB LED. These LEDs are driven by a Raspberry Pi and NPN transistors through a ribbon cable.
The plan was to imitate the Communicator status colors of green for available, red for busy, and yellow for away. [fiddlythings] dialed up a lovely shade of amber for away using a mix of red and green. Since he really only needs two colors, he’s using eight NPN transistors instead of twelve. The quick ‘n dirty proof of concept version used Python and a Pidgin IM console client called Finch. Once he got IT’s blessing, he implemented the final version in C++ using Libpurple to interface with Communicator.
This isn’t the first time we’ve seen a Pi used to indicate status—remember this mobile hackerspace indicator?
Things don’t always run the way we want them to or operate at the ideal temperature out of the box. Instead of spending extra for power controls that may or may not meet your needs, wouldn’t it make more sense to dial in the ideal level from the source? That’s what [dekuNukem] had in mind when he decided to make

Would you believe that some people think the internet is a time waster? Well, not at this particular address of course, but we can think of some other sites that are absolute rabbit holes without so much as a rousing game of croquet at the bottom. If you need help achieving what Tim Ferriss dubbed a Low Information Diet, there are browser extensions that will block your access to sites that keep you from getting things done. [Ivan’s girlfriend] has taken this time management tack seriously and even created a simple web page that states “Don’t Waste Your Time!” that will show if she tries to get to Facebook.
How ’bout that 2048 game? Pretty addictive, huh? Almost as addictive as embedded systems are, at least if you’re [Andrew]. Armed (pun intended) with a Nucleo F4 and a Gameduino 2 shield, he decided to have a go at making
