C Sharp Development 101 – Part 1: Hello World In this tutorial we are going to get up close with the Visual Studio 2010 environment. We will learn how to make a console application as well as a form to display our hello world applications. This will give us an opportunity to view 2 types [...]
Magnets Capable of Brain Hacks It has been recently discovered that all of the snap decisions that your brain makes on which hand to use to do simple tasks, such as picking up an object from a table, can now be automatically decided for you. This is done using magnetic stimulation that is applied using [...]
Launchpad not limited to value line chips Wanting to use my TI Launchpad as more than just a development board I thought I’d do a few experiments using it as an in-system programmer. After a few tripping points I was able to get it working and then some. It seems that the device is not [...]

DRM causes vulnerabilities We often hear people touting the evilness of DRM, but usually they are talking about the idea of ownership. In this case, DRM is actually causing harm. It turns out that Microsoft’s msnetobj.dll, which is supposed to enforce DRM on your computer, stopping you from doing certain things like saving files you [...]
Laser mic makes eavesdropping remarkably simple Here’s a surprisly simple way to build yourself a laser-based listening device. It consists of two modules, a transmitter and a receiver. The transmitter is a set of lasers, one is visible red for aiming, and the other is infrared for measuring the vibration of a surface. Point the [...]
Unmanned ocean crossing This is the Pinta, an autonomous sailboat built to attempt an ocean crossing from Ireland to Martinique (in the Caribbean). A group of researchers at Aberystwyth University built her as part of the Microtransat Challenge. To keep tabs on the vessel her creators included an Iridium short burst data modem with a backup system made [...]
WiFi AP gets antenna augmentation Feeling bad that his access point was being made fun of by models with beefier external antennas, [Customer Service] decided to do something about it. After cracking open the Asus wl-330ge he found it would be quite easy to add a connector. This access point has two internal antennas that [...]
Build a tetrahedral ambisonic microphone [Dan Hemingson's] been refining a design for building a tetrahedral ambisonic recording system. This is a set of four microphones used to record audio that can later be mixed down for a three-dimensional listening experience. His goal is an easy and inexpensive build while maintaining the highest fidelity standards possible. [...]
Small and simple FM radio [gpsKlaus] built this little FM radio (translated) based on the AR1010 IC. That chip is controlled via I2C by an ATtiny45 microcontroller. His tuning implementation relies on presetting 16 stations in the firmware and selecting them with the white potentiometer. The FM chip came on a breakout board from SparkFun. [...]
