While not everyone agrees on the installation of wind turbines in their proverbial back yards, one thing not up for debate is that there is a drive to build them bigger, and bigger. Big turbines means big blades, and big blades need to be transported… somehow. If air freight is going to stay relevant to […]
Tent camping lets you explore places on foot you could never reach another way, but sometimes you want to camp with a bit more luxury. [Levi Kelly] decided to see how small you could make an RV. [via Autopian] While we won’t argue one way or another on his claim to world’s smallest, as that […]
The wheels on roller suitcases are one of their primary failure points. After the destruction of the wheel mount on her DIY suitcase, [Laura Kampf] wondered if it would be better to dispense with wheels altogether. To give her suitcase a lift, [Kampf] decided to turn it into a hovercraft so it couldn’t be stopped […]
For RC aircraft there are generally legal restrictions that require the craft to stay within line of sight of the operator, but an RC boat or car can in theory go as far as the signal will allow — provided there is ample telemetry to let the operator navigate. [Thingify] took this idea to the […]
Of the many great technological leaps made in the middle of the 20th century, one of the ones with perhaps the greatest impact on our modern life takes a back seat behind the more glamorous worlds of electronics, aeronautics, or computing. But the ancestor of the modern tractor has arguably had more of an impact […]
Nautical navigation has a long history of innovation, from the compass and chronometer to today’s computer-driven autopilot systems. That said, the poor compatibility of electronics with saltwater has consequently created a need for rugged, waterproof computers, a category to which [Matti Airas] of Hat Labs has contributed with the open-source HALPI2. Powered by the Raspberry […]
If you take the wheels off a FIAT Punto, you might just notice that those rims fit nicely on a rail. [AT Lab] did, and the resulting build makes for a very watchable video. Some of us have been known to spend a little too much time chasing trains, and there’s little on rails that […]
Ultralight aviation provides an excellent pathway for those who want to fly, but don’t want to get licensed. These quite often cheap and cheerful DIY aircraft often hide some excellent engineering underneath. This is no more true than in [ultralight helicopter’s] four-year-long helicopter build saga! While most ultralight builds are fixed-wing, a rotocraft can meet […]
Often times, e-bikes seek to build the biggest battery with the most range. But what if you want to take a couple lunch loops on your bike and only need 20 minutes of charge? That’s [Seth] from Berm Peak set out to find out with his minuscule Bermacell battery. The battery is made from only […]
The JuiceBox charger in its natural environment. (Credit: Nathan Matias) Having a charger installed at home for your electric car is very convenient, not only for the obvious home charging, but also for having scheduling and other features built-in. Sadly, like with so many devices today, these tend to be tethered to a remote service […]
