Nintendo Switch Gets Making with Labo

Over the years, Nintendo has had little trouble printing money with their various gaming systems. While they’ve had the odd misstep here and there since the original Nintendo Entertainment System was released in 1983, overall business has been good. But even for the company that essentially brought home video games to the mainstream, this last year has been pretty huge. The release of the Nintendo Switch has rocketed the Japanese gaming giant back into the limelight in a way they haven’t enjoyed in a number of years, and now they’re looking to keep that momentum going into 2018 with a …read more

Color Changing Clock gets a Pi Zero Heart

Hackaday reader [Don] dropped by the tip line recently to let us know about the latest version of his color-changing LCD clock project. This is his second version of the hardware which makes some pretty big improvements over the original, including moving from the Pi B to the Pi Zero and an internal simplification of the wiring. He mentions the next revision of the project will focus on Google Home integration, which should be interesting to see.

Hazardous Dollhouse Teaches Fire Safety

Fire safety is drilled into us from a young age. And for good reason, too, because fire hazards are everywhere in the average home. Even a small fire can turn devastatingly dangerous in a matter of minutes. But how do you get kids to really pay attention to scary (and often boring) adult concepts? You can teach a kid to stop, drop, and roll until you’re blue in the face and still might not drive home the importance of fire prevention. Subjects like this call for child-sized visual aids that ignite imaginations.

That’s exactly what firefighters in Poznań, Poland did …read more

Educational Robot for Under $100

While schools have been using robots to educate students in the art of science and engineering for decades now, not every school or teacher can afford to put one of these robots in the hands of their students. For that reason, it’s important to not only improve the robots themselves, but to help drive the costs down to make them more accessible. The CodiBot does this well, and comes in with a price tag well under $100.

The robot itself comes pre-assembled, and while it might seem like students would miss out on actually building the robot, the goal of …read more
