.NET Gadgeteer - Microsoft’s open-source toolkit for building gadgets
By Pawel Piejko
DIY gadgets' makers have a new solution for quick and easy building of custom devices in the form of the .NET Gadgeteer platform. Utilizing .NET Micro Framework and C# programming language, .NET Gadgeteer is an open-source toolkit combined of a basic ARM CPU-equipped mainboard and a choice of easily attachable modules, including displays, buttons, camera, Ethernet, USB ports, or WiFi. The idea resembles the Arduino platform or EZ-Builder kit for DIY robotics projects like DJ Sures' WALL-E.

DIY Spy Drone Sniffs Wi-Fi, Intercepts Phone Calls
By Kim Zetter Email Author
LAS VEGAS — What do you do when the target you’re spying on slips behind his home-security gates and beyond your reach?
Launch your personal, specially equipped WASP drone — short for Wireless Aerial Surveillance Platform — to fly overhead and sniff his Wi-Fi network, intercept his cellphone calls, or launch denial-of-service attacks with jamming signals.
These are just a few of the uses of the unmanned aerial vehicle that security researchers Mike Tassey and Richard Perkins demonstrated at the Black Hat security conference here Wednesday.
At a cost of about $6,000, the two converted a surplus FMQ-117B U.S. Army target drone into their personal remote-controlled spy plane, complete with Wi-Fi and hacking tools, such as an IMSI catcher and antenna to spoof a GSM cell tower and intercept calls. It also had a network-sniffing tool and a dictionary of 340 million words for brute-forcing network passwords.

Rich Decibels Brainwave Disruptor
Audio-visual brain entrainment using an Arduino
There are some interesting theories about the ability of low frequency light and sound to alter brain states. I created the Rich Decibels Brainwave Disruptor to investigate some of the theories.
Electrical activity in the brain is rhythmic. The frequency of this rhythm depends on the state the brain is in: an active, alert state correlates to rhythms in the range of 30-100Hz. As brain activity reduces in frequency, so the brain state changes: 8-12Hz is associated with relaxation, 4-7Hz with meditation, and below 4Hz indicates deep sleep.
The concept behind ‘brainwave entrainment‘ is the idea that you can induce different brain states by causing brainwave frequencies to fall into step with external stimulus.
Concept
My device generates this external stimulus with binaural beats, by creating two tones whose frequencies are separated slightly, along with flashing lights and a pulsating audio filter.
