Review of the CAM8100-U USB Camera with the RIoT Android Board

In my earlier post, I was running into the ‘single camera’ trap of the current RIoT Android OS image: with only one camera attached, and switching between front/back camera, Android is stuck and needs to be flashed again to the board.

The 'What Time Did My Son Wake Up?' Project

My 2 1/2 year old son wakes up before us during the spring and summer. He turns his light on fully, and plays until he's bored. The problem was: exactly when was he waking, because it would affect how tired he was in the day (and affect nap times). So I built a tiny Arduino prototype :-)

Developing with a Sense of Direction: Hackstock for #LocalGov

It's a familiar trend when it comes to hackathons - to startup-centric software development in general, maybe - that the app comes first, and the reason comes second. Hackstock for #LocalGov, on the other hand, is an interesting twist on this tradition.
