Tech Epiphanies: Understanding the ‘Internet of Things’

In this podcast from the sandbox, our department director, John McAdam, muses on an internet-connected toothbrush, first unveiled at the Consumer Electronics Show in early January.

Taking a look at the high-tech toothbrush

The start-up behind the brush is Kolibree and it aims to make dental health a quantified-self pursuit. The proposal is that you use the smart toothbrush (not yet available in stores, but there’s a Kickstarter coming soon) and then it sends data via Bluetooth to your smartphone app.

In the podcast, John talks about how he made the connection between this idea of Internet of Things—all kinds of smart devices, not just phones—and the computer-code-like numbering system dental hygienists use to communicate about teeth.

How John’s musing was made

After inspiration hit, John typed up his script in a Word document, embedded here through Scribd, a free document-sharing site.

He then recorded his speech (using a headphone mic) directly into Audacity, a free audio editor and recorder.

Finally, he found a backing track—”Didgespiral” by Tomas Bown, downloaded from—and then added it via Audacity. After exporting to a MP3, we uploaded that file to Soundcloud, a free audio-hosting site that allows for track embeds (and Creative Commons licensing).

And that’s it! With free & cool social media tools (including this free WordPress blog), we shared an audio track with the world. In this case, it was John’s musings, but it could also be an instructor’s lesson or a student’s assignment.
