Ever wanted a development kit that flies? Well now you can! The Crazyflie is an open source nano quadcopter kit designed for flexible development and hacking. It's among the smallest in the world, weighing only 19 grams and measuring 9 cm motor to motor.

In very simple terms, the POV globe is a ring of RGB LEDs that is rotated axially at high-speed (300 rpm). Due to this high-speed and the phenomenon of persistence of vision (POV), our brains interprets this moving ring of light as a solid, spherical surface. By changing the colours of the LEDs very quickly, we can display images on this spherical surface. Mounted inside the ring is a Raspberry Pi (RasPi), a small, single-board computer that has become popular in the last couple of years. Its small-size and lightweight design make it ideal for this application. The RasPi has an HDMI output and therefore a custom FPGA-based HDMI decoder was designed and implemented for this project. The decoder takes the HDMI signal and converts it into a form suitable to be displayed on the ring of LEDs.

The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user. Beware, though: What you are about to see is not particularly elegant. In fact, the TTY subsystem — while quite functional from a user's point of view — is a twisty little mess of special cases. To understand how this came to be, we have to go back in time.

A new study has shown that Apple’s lawsuit against Samsung has actually helped spike sales for the South Korean firm.

...

The report argues that the press coverage not only helped Samsung become a recognisable name but the constant comparisons between the iPhone and Samsung’s Galaxy S III suggested that the devices were rather similar thus making them a decent option for consumers to consider. A key point to be remembered is that after the verdict in early September, the Galaxy S III outsold the iPhone 4S for the first time ever in the US.

Targeting cinematographers, journalists, scientists and hobbyists, the eye3 isn’t just a toy but packs enough power to hoist weighty (and expensive) 35mm dSLR cameras or even 16mm motion picture cameras with mounts. It has a durable, high precision carbon and glass fiber frame that weighs just half a kilogram. It uses the popular APM2 open source autopilot platform. Each of the six rotors is powered by a 350-watt motor. The six rotor design is a safety measure: two rotors can fail and the copter will still be brought back safely.

PsiXpda, who you may remember channeled some classic Psion nostalgia for their UMPC in late 2009, is planning a second attempt on the companion device market with a design that sticks more faithfully to the fondly-remembered Series 5mx.

...

Rather than attempt to squeeze a desktop OS onto the new PsiXpda, Pinnock intends to use Android, which should add up to longer battery life and more consumer appeal. Although we’ve seen Android MIDs with physical ‘boards before, they’ve always been intended for thumb-typing rather than anything more ambitious. No word on when PsiXpda intends to release the new model, but we’re tentatively curious to see if its second attempt can do a better job of living up to the Psion inspiration.

So, an Android device with a Psion keyboard? Yes please! If my Psion 5mx had wifi, or 3G, or GPRS, or Bluetooth, or any other reasonable way of communicating with anything else, I'd still use it to this day.

The WilliamsWarn Personal Brewery has six main technical features that, when combined together, create the world's first all-in-one brewing appliance. This combination then allows you to make the freshest beer on the planet with minimum effort.

This thing looks ridiculously cool. Makes me wonder though... I'm sure a total noob (like me) can use it to make okay beer -- but would a skilled brewer (like I would want to become if I had one of these) be able to make excellent beer with it? Then I'd want one. Or at least I would if I had somewhere to put it. It's pretty stylish, but not something I'd want in my living room.

OpenPilot is a next generation Free Software autopilot for small UAVs, including multi-rotor craft, helicopters as well as fixed wing aircraft. It aims to implement the best features of all current enthusiast autopilot systems and combines them into a simple easy to use package. Simplicity does not come with any compromises either, with no hard-coded settings, a complete flight plan scripting language and other next-generation features, OpenPilot is planned to be an extremely capable UAV platform.
