The LedBorg provides a tri-colour LED controllable from the Raspberry Pis GPIO header. Using simple on / off logic it can provide a total of seven colours as well as off. Using software based pulse width modulation (PWM) it is capable of many more colours, around a million in fact.

Quadcopters are great at hovering, but don’t have long range. Fixed-wing aircraft can travel long distances quickly, but don’t like to stay in one place above the ground.

Krossblade’s SkyProwler solves both of those problems. The hybrid aircraft is a remote controlled quadcopter with wings, or a plane with six rotors, capable of vertical takeoff and landing (VTOL).

The USB Weather Data Receiver USB-WDE1 wirelessly receives data from various weather sensors of ELV at 868 MHz. The receiver is connected to a USB port on the computer, so no additional power supply is required. The data is transmitted via a simple serial ASCII protocol, which is well documented by ELV. The RasberryPi running Raspbian is used for the data acquisition allowing very little power consumption while being completely flexible.

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.
