The Raspberry Pi isn’t just for Linux anymore. For just over two years, Microsoft has offered a version of Windows 10 that works on the Raspberry Pi called Windows IoT Core. In January 2016, Microsoft created a project that uses Windows IoT and its Project Oxford facial recognition technology to create a smart home door lock.
All you do is stand in front of the door, press the buzzer, and if you’re recognized the door unlocks. Microsoft actually used an Intel MinnowBoard Max for its example, but a Raspberry Pi would work as well, as detailed by Microsoft on Hackster.io. Microsoft’s setup was only a proof-of-concept and therefore something of a kludge, but anyone wanting to do this at home could easily make it look much nicer with a little effort.
That said, we can’t vouch for the system’s security, as Project Oxford is about detecting faces in images—which means a person with a picture of you might be able to defeat the system. Nevertheless, it would be a fun home project and shows off what you can do with a Raspberry Pi and some extra hardware.
