Everybody is busy these days, but sometimes it’s hard to tell. What with teleconferences being conducted over tiny Bluetooth headphones and Skype meetings where we seem to be dozing in front of the monitor, we’ve lost some of the visual cues that used to advertise our availability. So why not help your colleagues to know when to give you space with this shark themed WiFi-enabled meeting light?
Why a shark and not a mutated intemperate sea bass? Only [falldeaf] can answer that. But the particulars of the build are well-documented and pretty straightforward. A Photon runs the show, looking for an Outlook VFB file to parse. An RGB LED is used to change the color of the translucent 3D printed shark based on whether you’re in a meeting, about to step into one, or free. The case is 3D printed as well, although [falldeaf] farmed the prints out to a commercial printing outfit because of the size and intricacy of the parts. He did fabricate a nice looking wood base for the light, though.
There are plenty of ways to tell people to buzz off, but this is a pretty slick solution. For those in open floor plan workspaces, something like this IoT traffic light for you and your cube-mates might be in order.
Calling Canada home, Hackaday reader [TheRafMan] has seen his share of bitterly cold winters. He also knows all too well how hard it is to get his cars started in the morning if somebody happens to leave the garage open. After the door was left open overnight for the second time this last winter, he decided that it was time to add an indicator inside the house that would alert him when the garage had not been closed .
Inspired by our BlinkM Arduino coverage a short while back, his circuit incorporates a BlinkM as well as several other components he already had on hand. He disassembled the garage door switch situated in the house and fit the BlinkM into the switch box once he had finished programming it. A set of wires was run to the BlinkM, connecting it to both a power supply located in the garage as well as the magnetic switch he mounted on the door.
The end result is a simple and elegant indicator that leaves plenty of room for expansion. In the near future, he plans on adding an additional indicator strobe to let him know when the mail has arrived, not unlike this system we covered a few months ago.
Stick around to see a quick video demonstration of his garage door indicator in action.
In his line of work, Hackaday reader [Pedantite] often has to monitor the build status of several continuous integration servers throughout the day. One afternoon, he got the idea to install a set of stop lights in the office in order to monitor the status of the servers, but filed it away as a “wouldn’t it be cool if…” project.
After some time had passed, he was bitten by the idea bug again and decided he would build a physical device to display the status of his build processes. This time around, he brainstormed on a smaller scale and the result is the “Indictron” you see above.
He built a simple LED board made up of four rows of four LEDs to display the build processes. Different LEDs are lit depending on the project’s current build status as well as the results of the previous build. The board uses an ATmega88, and interfaces with a compiler watchdog application using a virtual USB package made specifically for AVR micro controllers.
The end result is a simple, yet useful status board that “just works”. He does not seem to have code or schematics posted on his site at the moment, but we’re pretty sure he would share them upon request.
