When WiFi imitates art
For most of us, the only way we can see the strength of a WiFi network is by the familiar signal icon on any given device. Newcastle University School of Architecture doctorate student Luis Hernan, however, has a different method: spirit photography. He's using the new age-y method of capturing someone's aura via electric coronal discharges -- a Kirlian Device -- with a few geeky augmentations (an Arduino Uno board and WiFi Shield, for example) to illustrate how strong a wireless broadcast is with colors. As Wired notes, these components take account of the nearby signal and convert it into color information that's then beamed onto an LED strip; red being the strongest and blue being weaker sections of the network. To create the pictures like what you see above and at the source, Hernan swung the home-made device around after setting up long-exposure shots with a camera. While we can't know for sure, we'd imagine that something with no signal would look a lot like this.
Arduino brings the (new) goods to Maker Faire New York, welcomes ARM into the fold
When Arduino unveiled a boatload of new products on Friday, we could have taken the easy route, posted the PR and called it a day. But, since the crew happened to be in town for Maker Faire, with a few folks from Atmel (makers of the AVR chip at the heart of the open source MCU) in tow, we figured why not go straight to the source. Arduino founder Massimo Banzi gave us a look at the company's latest offerings: the ARM-powered Arduino Due, the low-cost Arduino Leonardo, and aptly-named Arduino WiFi, as well as a peek at some of the group's upcoming plans. Keep on reading after the break for the juicy details.%Gallery-134242%
