Fresh hacks every day
[Matt the Gamer] loved his pair of Minimus 7 bookshelf speakers. That is until a tragic hacking accident burned out the driver and left him with a speaker-shaped paper weight. But the defunct audio hardware has been given new life as a single portable powered speaker. Now he can grab it and go, knowing that it contains everything he … Read the rest

Copper vapor lasers require temperatures of about 1500° … Read the rest

As you may have noticed from some of the posts we’ve done on his projects, [Mikey] lives in the middle … Read the rest
Fresh from Microsoft Research is an ingenious way to reduce interference and decrease the error in a Kinect. Bonus: the technique only requires a motor with an offset weight, or just an oversized version of the vibration motor found in a pager.
Being the first of its kind of commodity 3D depth sensors, the tracking on a Kinect really isn’t … Read the rest
