Triangulating the office dog
Emma, our office manager, has forbidden us any office pets of the higher orders. She has said she’ll allow hissing cockroaches, which was a singularly unpopular option. (Emma has a PhD in entomology – the study of insects – and we’re worried she’s serious.)
Hissing cockroaches, like dogs, tend to wander (cockroaches do it in more of a scuttling style than dogs, but the principle holds), and in a large office with many rooms, it can be hard to locate your pet. So we are extremely impressed by the problem-solving hacking of the folks at Red Pepper, a digital agency in Atlanta and Nashville, whose office dog is a) adorable and b) bionic. Bean the greyhound wears a collar fitted with a beacon, and Red Pepper’s office is equipped with three bluetooth-sniffing Raspberry Pis, so she can be located at all times.

We are unclear on whether this approach will work with cockroaches.
Matt Reed, Bean’s caretaker, and Red Pepper’s hacker-of-things, is behind the project. He says:
Beacons are usually placed in stationary locations such as displays or areas of interest in retail stores. They emit a polling signal every second or so that any device with BLE (Bluetooth Low Energy) can pick up, your phone being one of them. That signal includes a few unique IDs and a value called an RSSI (Received Signal Strength Indicator) which basically tells how close you are to the beacon.
If you have an app that is configured to listen for a beacon with a certain ID it can make things happen behind the scenes. For instance, at a retailer, the app could determine if you’re standing in front of a pair of jeans and then tell a server on the internet this information. The server can then send out a push notification giving you a deal on jeans.
For Sniffur we flipped this scenario and put the normally stationary beacon on a moving dog. The signal strength then emits from the dog for our three antennas to pick up and process.
You can read more about the build, and about Bean, over at Red Pepper’s website. Thanks Matt – please give Bean a cookie for us!

This is a very cool idea! I will be sure to visit Bean and the people she owns (let’s get the relationship straight – who’s buying the food, toys, etc.? :) since I’m in the neighborhood!

I’ll have to see a man about a dog…and a Pi. (Sorry…)
Jean-Louis Z, one of our Rhône Valley Jam (and Cour_Tech_Zone fablab) friends, is a major Open Street Maps France and Mapillary head. He was wondering how we might triangulate inside buildings using Bluetooth and RPI to place his 360° photos on the Maps and for building interior documentation/surveys.
Et voilà, a big part of an answer….I think he’ll be pretty interested in what Matt and Bean have been getting up to =o)

Back in the day, lower order pets (aka grad students) could be tracked in the computer dept by active badge technology.
Haven’t been back there for years – is it still used / what happened to it?

I believe the setup is still in the CL. Not sure how much use it gets these days. But the creators of the active badge went on to found a company to commercialise the tech – Ubisense.

1) You will need very tiny collars to put on your cockroaches.
2) Was that Emma in yesterday’s xkcd?
