Homebrewed Voice Assistant Keeps An Eye On Air Quality via hack a day

Voice assistants are now available from a wide variety of companies, however, [7402] didn’t like the idea of these devices sending data off to the cloud for potentially-nefarious purposes. Thus, the goal became to build a home voice assistant that worked entirely offline, and that’s precisely what [7402] achieved.

The system had limited goals compared to commercial competitors. [7402] was more than happy to deal with a limited vocabulary of understanding as a trade off for privacy. It’s all built around a Raspberry Pi Zero, which runs the Julius speech recognition library. Ultrasonic sensors are used to only activate the device when a person leans in and directly addresses the system.

Along with the busy schedules of two working parents you might have art classes, karate classes, Little League, soccer and more. Add in more than one kid and organizing your life can quickly become a nightmare. This is exactly why one of my most important organizing devices is a shared calendar that reflects all the activities and events for everyone in the household...and I do mean everything.

Google Docs adds templates

Even as a computer consultant, I find that I use probably less than 10% of the features in any of these projects. One feature I really like in Google Docs is the easy, online file sharing that also allows you to edit simultaneously with someone else.
