This human flight hoax has been picked up by all the tech and gizmo blogs within the past 12 hours. http://www.wired.com/wiredscience/2012/03/human-bird-wings/ They have Youtube videos going back several months, working machines, blueprints, blogs, press kits... pretty impressive. The videos on the whole seem vaguely like some kind of fake European viral advertisement, but if you […]
Display-Aided Head Tracking
If you've ever used Apple's PhotoBooth software to take a picture of yourself with the webcam built into the screen, you'll notice the display turns white when the picture is taken. The idea is to use the monitor as a flash bulb - it illuminates your face and produces a better image in low-light conditions. […]
Wave field synthesis graphical simulation
This is a Processing sketch/Java applet that simulates wave field synthesis. A virtual source follows the position of the mouse cursor. It's useful for visualizing the behavior and limitations of WFS. Right now it lets you change parameters of a line array, and I'll try to extend it to simulate other array configurations. Key Commands: […]
Wave field synthesis build progress
Spent the week building speakers. 12 modules complete (48 speakers). Have yet to wire them all up. Still waiting on a few power adapters.

Wave field synthesis first speaker module
I built the first WFS speaker module and it turned out well. Now I have to build 11 more before Christmas. Just like Santa's workshop 🙂
Wave field synthesis array plans
Plans are coming along for construction of the ALMWFSLA (pronounced "almwfslah"), or Absurdly Large Modular Wave Field Synthesis Loudspeaker Array. The modules will be 18" x 4.5" with an open-back enclosure. This will allow for a 4'-6" x 3' plane array, a full surround line array 11 feet in diameter, and many more fascinating configurations. […]
