New Project: Make an EEG Beanie That Reads Your Mind
Time required: A weekend Cost: $100 — $130 Ever wanted to visualize your brain activity? Electroencephalography (EEG) uses electrodes placed against the scalp to detect the tiny electrical changes that occur when neurons fire. By amplifying these signals through a computer, you can observe brain activity in real-time. Using an […]BITalino (r)evolution: Circuits for Quantified Self and More
We first met Hugo Silva last year when he introduced us to Bitalino, an Arduino-compatible electronics toolkit designed for exploring the various physiological signals that the human body gives off. The latest iteration of the platform, BITalino (r)evolution, is more affordable and capable than ever, but the team still needs […]Bringing makers back to the Lab

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.
