Fresh hacks every day
This one is so simple, and works so well, we'd call it a hoax if April 1st hadn't already passed us by. But we're confident that what [William Myers] and [Guo Jie Chin] came up with exists, and we want one of our own. The project is a method of drawing in 3 dimensions using ultrasonic sensors. They call it 3D Paint, and that's fitting since the software interface is much like the original MS … [Read more...]
[Dave's] drawbot writes his Facebook wall messages on a whiteboard. The setup is pretty simple, depending on a pair of stepper motors and common household goods. As you can see in the image, the stylus is a plain old dry-erase marker held by a big spring clip (the kind that holds a stack of papers together). What you can't see is that there's a kick stand to hold the writing head away from the … [Read more...]
No matter how good the intentions or how strong your hack-fu may be, sometimes you just can't cross the finish line with every project. Here's one that we hate to see go unfinished, but it's obvious that a ton of work already went into reclaiming these smart white-board projectors and it's time to cut the losses. The hardware is a Smartboard Unifi 35" computer with a projector mounted on a … [Read more...]
The Wiimote is a fantastic tool for hackers, given their affordability and how easy they are to work with. [Gareth] had a "eureka" moment while working on another Wiimote-based project, and with some alterations, converted it into an electronic whiteboard. The whiteboard was built using the IR sensor he extracted from a Wiimote, which is wired to an EasyProp board to process the input. The … [Read more...]
White board beats chalk board, LED marquee beats white board, and an LED white board trumps them all. This hybrid lets you draw on the surface with dry erase markers while Conway's game of life plays out underneath. [Bert] sent us this tip after seeing yesterday's office marquee. This version is quite similar in appearance but the guts are very different. Inside you'll find a Parallax SX28 … [Read more...]
[Raj Sodhi] and [Brett Jones] have been working on interactive augmented reality as part of their research at the University of Illinois. What they have come up with is a stylus-based input system that can use physical objects to create a virtual landscape. Above you can see that an environment was built using white blocks. A camera maps a virtual world that matches the physical design. From there … [Read more...]
Check out the video above by [Adrien Mondot] for a extensive demonstration of eMotion being used with a Wiimote. eMotion is a physics based visual tool for the Mac. It's designed to enhance performances by reacting to real world motion. Its grounding in physics makes the resultant motion appear more natural than if they were arbitrarily generated. The video above combines eMotion with the output … [Read more...]
