Surprisingly Simple Arduino Motion-Sensing Project Makes For Some Weekend Fun article tells that Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your desk or into a room. It’s completely open source and the notifications system runs on your PC thanks to a simple Python script. Why is →
Three phases of owning a computer is a funny poster you can find at the Oatmeal. Look at it. It is the special link for this Friday. →
GPU computing is a hot topic at the moment. GPU computing is the use of a GPU (graphics processing unit) as a co-processor to accelerate CPUs for general-purpose scientific and engineering computing. General-purpose computing on graphics processing units (GPGPU) is the means of using a graphics processing unit (GPU), which typically handles computation only for →
The NSA Is Building the Country’s Biggest Spy Center (Watch What You Say) article tells that the NSA has become the largest, most covert, and potentially most intrusive intelligence agency ever. Under construction by contractors with top-secret clearances, the blandly named Utah Data Center is being built for the National Security Agency. A project of →
UNDERSTANDING, FINDING, & ELIMINATING GROUND LOOPS IN AUDIO & VIDEO SYSTEMS – 2005 Generic Seminar Template is a very good collection of information on ground loop problems on audio and video systems. The writer Bill Whitlock from Jensen Transformers really knows what he is talking about. Here are some fact points picked from document: The →
IGNITION WEST: Future of Mobile article constains an interesting slide set that puts together a deck on the current trends in mobile. The slide set by BI Intelligence service looks closely at the growth of smartphones and tablets, the platform wars, and how consumers are actually using their devices. Android will be the OS of →
Have you ever wanted to find out how strong a magnet really was, or how the strength of the magnetic field varied as you changed the distance from the magnet. Devices used to measure the local magnetic field are called magnetometers or gaussmeters. There are commercially available meters for this, but they are usually a →
When I was a kid, there was a periscope you could make out of a cardboard tube and two small hand mirrors to see around corners. Now there’s a video camera system that can do the same. Camera Can See Around Corners and Femtosecond Camera Sees Around Corners articles tell that Scientists at the Massachusetts →
If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. How-To: Shrinkify Your Arduino Projects video and How-To: Shrinkify Your Arduino Projects article shows you how. The best part is you can use the same Arduino code and →
I have earlier written about a tiny Tetris. Not is time for a big Tetris. At MIT, fun is accomplished with architecture. Hackers turn MIT Building into Tetris Game. MIT hackers have, for some time now, considered playing “Tetris on the Green Building” to be the mother of all MIT hacks because “the side of →
