Epic staircase incorporates cinema, library, and playroom

The architects responsible for the Panorama House have made a staircase of epic proportions that acts as a functional centerpiece of the house. The staircase serves as a multifunctional hub, not only providing a way to get from downstairs A to upstairs B, but forming a central element of the house's library, cinema, and play area.Designed by Moon Hoon, the Panorama House is located in Chungcheongbuk-do, South Korea, and while the whole building is magnificent, it's the staircase that really stands out. It is gargantuan, with the stairs themselves representing just a small part of the structure (as can be seen in the gallery). Those heading down to the lower floors can take the stairs or use the slide instead, with kids and adults alike invited to experience the latter.The individual steps provide storage space for books, while the space underneath the staircase itself is used as an office, with plenty of room for a desk and chair. Last but not least in this staircase's box of tricks are the seating areas which the family who reside in the house can use while watching films projected on the back wall.

Nerf Vulcan Sentry Gun tracks targets and avoids friendly fire

Anyone who plays video games will know that few things protect an area like a well-placed sentry gun. In the real world, though, even a person's bedroom or office could use a little protection sometimes, which is why one designer has built the Nerf Vulcan Sentry Gun. Using a custom program and some servos, the sentry can automatically locate targets and unleash a stream of foam darts at over seven times the usual speed, while keeping its owner out of the crosshairs. Britt Liv Ulrike Michelsen, a chemical and biological engineering student from Germany, designed and constructed the sentry using mostly basic electronics and some plywood. This isn't the first time she's modified a Nerf gun, but building this robotic turret is arguably her most ambitious project to date. Luckily, the Nerf Vulcan already operates using an electric motor, so controlling the actual firing mechanism through a computer was just a matter of connecting it directly to an Arduino Uno and a laptop. ...

Students crash rockets to develop new asteroid sample collection technique

In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it's actually a serious effort to develop new ways of collecting samples from asteroids. The test was part of the “Sample Return Systems for Extreme Environments” project. The idea is to find cheaper, more efficient ways of collecting samples from asteroids and hazardous areas on Earth, such as volcanoes and nuclear disaster zones, by using penetrators instead of soft landers or ground crews to hammer out sample cores. According to the team, this would result in lower cost than soft landing techniques by reducing the velocity and vehicle mass needed to gather the sample, minimizing damage on impact, as well as being mechanically s...

Review: i-H2GO hydrogen-powered remote-control car

At the end of last month, Horizon Fuel Cell Technologies began shipments of its latest hydrogen fuel cell-powered remote-control toy car, the i-H2GO . Like its predecessor, the H2GO , it runs on hydrogen obtained from user-supplied water. The main thing that's new about the i-H2GO, however, is the fact that it is now controlled using a free app on the user's existing smartphone. I got my hands on an early production model, mainly just so that I could truthfully say "I've driven a fuel cell car." Like the H2GO, the new car comes with an included Refueling Station. The user pours purified water into that device, and it proceeds to electrolyze the H2O, separating it into H and O – hydrogen and oxygen. A plunger on the station rises as hydrogen fills its temporary holding compartment. The user then connects the car to the station using a built-in hose, and manually pumps the hydrogen from the station into the car. The car's fuel cell subsequently combines...
