Imagine being asked to provide sound reinforcement for a meeting that occurs in a large room, where anyone can be the speaker, and in a situation where microphones would hinder the flow of the meeting. Throw in a couple of attendees who have hearing disabilities, and you’ve got quite a challenge to make sure everyone gets heard.
Such a situation faced [David Schneider] at his Quaker meetinghouse, which he ended up solving with this home-brew audio induction loop system. The worship style of conservative sects of the Religious Society of Friends, as the Quakers are formally known, is “silent worship”, where congregants sit together in silence until someone feels moved to share something. Anyone can speak at any time from anywhere in the room, leading to the audio problem.
Rooms mics and a low power FM transmitter didn’t work because those using radio as aids to hearing the service felt awkward, so [David] decided to take advantage of a feature in the hearing aids worn by some members: telecoils. These are inductive receivers built into some hearing aids to send sound directly to them using magnetic fields generated by a loop in the listening area. [David]’s loop ended up being 240 meters of 20-gauge copper wire in the attic above the meeting room. The impedance ended up close to 8 ohms, perfect for feeding directly from the speaker terminals of an old stereo amplifier. Pumping 160 Watts into the coil allows the hearing-aid wearers below hear the service now.
There’s still work to be done on the input side to improve audio quality, but [David]’s solution is elegant in that it helps those who need it most using technology they already have. And perhaps those who need but don’t yet have hearing aids can roll their own.
Flow requires a certain amount of focus, and when that concentration is broken by pesky colleagues, work can suffer, on top of time wasted attempting to re-engage with the task at hand. The Technical Lead in [Estera Dezelak]’s office got fed up with being interrupted, and needed his own personal assistant to ward off the ‘just one question’-ers.
Initially, [Grega Pušnik] — the tech lead — emailed the office his schedule and blocked out times when he wasn’t to be disturbed, with other developers following suit. When that route’s effectiveness started to wane, he turned the product he was working on — a display for booking meeting rooms — into his own personal timetable display with the option to book a time-slot to answer questions. In an office that is largely open-concept — not exactly conducive to a ‘do not disturb’ workstation — it was a godsend.

Meetings can actually be useful. It’s hard to believe, but they can actually save time if done right. While most of us are in a perpetual state of torture by Kevin in marketing holding another three-hour meeting during lunch hours, there are a few of us who know their hidden power when put in the right hands.
Working as a contractor, wasted meetings mean wasted billable hours. Even wasted meeting time is covered in the cost of the contract it runs the risk of giving the client the impression that you’re not as productive as originally thought. Organized, productive meetings show that you know what you’re doing and that the cost of your services as a whole is a good value. Yeah, some meetings suck but they are necessary and should be productive.
A meeting needs three things to be worth the time spent on it.
- A well prepared for, simple, and clear agenda.
- A time limit.
- Something needs to be written down at the end of it.
I’ll start with the third item as it shapes the rest. The point of a meeting is to have something to write down at the end of the meeting. Any meeting that ends up in anything requiring fallible human memory was a waste of everyone’s time. This includes, verbal agreements, handshake agreements, ideating (pronounced idioting), brainstorming, think tanking, and the like.

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.
