Ever wanted to listen to something without anyone around you hearing it? While you certainly could go with a pair of headphones, there’s something that just seems that much cooler about using a parametric speaker instead.
I always enjoy checking out the TokyoFlash design blog for new modern watch concepts. Sure, many of them are impractical, some of them are hard to read, but for the most part, they look pretty cool, like this concept design called Raitosho.
Here’s a cool hack which uses an old oscilloscope to play an accurate game of the arcade classic, Tetris.
Engineer Lars Pontoppidan created Scopetris using an AtMega32 micro-controller to drive the beam of an oscilloscope to mimic the game play of the classic Soviet puzzle game.
These ceiling mounted speakers from Holosonic Research precisely direct a beam of sound so it can only be heard if you’re standing directly inside the focused area they project.
Their square Audio Spotlight speakers easily mount in place of standard 2′ x 2′ ceiling tiles and project a perfectly focused tunnel of sound towards the people standing beneath them.
I’ve seen some interesting hackjobs in my day, but nothing quite like this. Builder Harold Ilano has built himself a little robotic insect from the remnants of an old Sony Playstation console.
Harold’s Mercury BEAM Robot was scavenged from a variety of junk parts, but an old PlayStation console was the primary contributor, giving the ‘bot its two motors and other internals that keep it chugging along.
This portable LED flashlight is the perfect source of illumination for reading maps or other documents in you car without disturbing the driver. The compact Auto LED provides a bright, sharp-edged beam, keeping light focused only on its intended target.
