Distance detecting pc

distance

Reader [Joshua] sent in his latest project. using a sonar rangefinder, an Arduino, and some clever programming, he’s made is computer react to his distance from it. As you can see in the video after the jump, he has programmed it to change text size and background color depending on his distance from the screen. While he admits that his implementation doesn’t seem immediately useful, there’s lots of potential  there. We can actually think of several uses. What would you use it for?

Banjo hero

We’ve posted a plethora of Guitar Hero style hardware hacks, but this one is completely different than the others. Behold, the Banjo hero. This unique controller was constructed from an old banjo and a guitar hero controller. Custom software was then built with custom songs for game play. We really wish we could see it in action. There are a couple videos available for download, but they are just pictures of the build process.

Tweet-a-Watt kits

[adafruit] wrote in to let us know that the Tweet-a-Watt is now available in kit form. While the plans have been available for a while, a kit is a welcomed addition. The kit doesn’t include the Kill-a-Watt monitor, but rather the XBee adapters and parts necessary to make it talk to your Arduino or computer. The kit is $90, while the Kill-a-Watt can be found for roughly $20.
