Baby’s first star light projector and a foil slip ring

For a newborn, everything is magical; a lack of object permanence means everything is new, wonderful, and novel. What then, could be better than a projected star field circling an infant’s room, gently sending them to sleep? [Pete] was inspired by this earlier starlight projector that projects a rotating star field onto the walls and ceiling of [...]

 
Adding new features and controlling a Kinect from a couch

Upon the release of the Kinect, Microsoft showed off its golden child as the beginnings of a revolution in user interface technology. The skeleton and motion detection promised a futuristic, hand-waving “Minority Report-style” interface where your entire body controls a computer. The expectations haven’t exactly lived up reality, but [Steve], along with his coworkers at [...]

 
The first Raspberry Pi build is a MAME machine

The Raspberry Pi was launched nearly a month ago, but these wonderful cheap single-board computers are still on their way from China to the workbenches of hackers and builders around the globe.

Aquarium water exchanger built from Keurig parts

We keep seeing commercials for those Keurig coffee makers that use a plastic pod of grounds to brew just one cup of coffee.

We’ve actually got a few dead hard drives collecting dust so when we hear about a project that finds a use for one we perk up a bit. But we were somewhat disappointed when we discovered this was a smartphone stand, pen holder, and LED lamp in one. We just don’t have a use for [...]

 

Huge apologies for going quiet on you. Eben and I have been on a skiing holiday, but I managed to fall and twist my knee quite badly in the middle of last week. Eben is a sweetheart and curtailed the holiday to take me down the hill to spend a few days in a rented [...]
