Door Bell 2.0 (or #DoorBell20 for short) is a Bluetooth Low Energy (BLE) appliance to monitor a door bell and send notifications whenever the door bell rings. It turns a conventional door bell into a smart door bell that can be connected to the Internet of Things (#IoT), e.g., through the DoorBell20 If This Then That (IFTTT) client. Thus, DoorBell20 is the modern version of a door bell, or, as the name suggests, the door bell version 2.0 for the IoT era.

Paper on Automatic Indoor Mapping @ Percom 2014

Patrick and me, we just arrived back from Percom 2014 in Budapest where we presented our work on automatic indoor mapping using crowds of mobile users (I should also mention that this was joint work with many other great colleagues from University of Stuttgart coming from photogrammetry and distributed systems). 

I think, the results are quite impressive, showing that it is indeed possible to use crowds of mobile users to automatically create complete high-quality floor plans, by opportunistically collecting mobility traces and a novel technique using structural knowledge about buildings to fill uncovered "white spaces" and further improve accuracy. 

If you are interested in the details, here are the links to our paper:

Very good point Faraz! That's exactly where the structural building information comes into play. We assume we have knowledge about the possible sizes of rooms (encoded into an indoor grammar). Then traces give evidence, which room we actually have by defining constraints on possible room layouts (users cannot walk through walls, ...). This helps us to correct these kinds of errors.

Testing USB-C to USB-A/Micro-USB Cables for Conformance

With this little Arduino-based tool you can test whether your UBS-C to USB-A/Micro-USB adapter conforms with the standard (includes a 56k resistor) or might damage your host.

#usb #usbc
Many new mobile devices now feature an USB-C connector. In order to connect these devices to USB devices or chargers with a USB-A or Micro-USB connector, you need an adapter or cable with USB-C plug on the one side and USB-A/Micro-USB connector on the other.

Can get Google Glass now ... hm, well, not really :(

I have received a nice email from Google telling me that now I (or better we = our research project at University of Stuttgart) could purchase Google Glass:

"We're seeking new Explorers and we're opening up some spots in the Glass Explorer Program. Any adult in the US can become an Explorer by visiting our site and purchasing Glass ... including you! "

However, obviously I am not an adult in the US (come on Google, you should have known, or at least have an educated guess by looking at my email address or the country field in the registration form). So "including you" should be replaced by "excluding you" ... once again. 

Sad but true ... we could have really used Glass for nice research prototypes. Guess we have to wait for the international version of Glass ...
