When you purchase your system with a mainboard and Intel x86 CPU, you are also buying this hardware add-on: an extra computer that controls the main CPU. This extra computer runs completely out-of-band with the main x86 CPU meaning that it can function totally independently even when your main CPU is in a low power state like S3 (suspend).

Wifatch’s code does not ship any payloads used for malicious activities, such as carrying out DDoS attacks, in fact all the hardcoded routines seem to have been implemented in order to harden compromised devices. We’ve been monitoring Wifatch’s peer-to-peer network for a number of months and have yet to observe any malicious actions being carried out through it.

The informatics researcher began his experiment by selecting a straightforward task for the chip to complete: he decided that it must reliably differentiate between two particular audio tones. A traditional sound processor with its hundreds of thousands of pre-programmed logic blocks would have no trouble filling such a request, but Thompson wanted to ensure that his hardware evolved a novel solution. To that end, he employed a chip only ten cells wide and ten cells across— a mere 100 logic gates. He also strayed from convention by omitting the system clock, thereby stripping the chip of its ability to synchronize its digital resources in the traditional way.

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.

Our USB Typewriter circuitry can transform your old manual typewriter into a retro-futuristic marvel. Use a gorgeous vintage typewriter as the computer keyboard for your Mac or PC, or type with ink-on-paper while electronically recording your keystrokes! The USB Typewriter also makes an outstanding keyboard dock for your iPad or tablet PC.

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.
