Fresh hacks every day
[Chonggang Li] wrote in to share a link to the final project he and [Ran Hu] built for their embedded systems class. It’s called Piano Hero and uses an FPGA to implement a camera-based touch screen system.
All of the hardware used in the project is shown above. The monitor acts as the keyboard, using an image produced by … Read the rest
We mourn the loss of the physical keyboard with the advent of tablets. After all, we do a bit of typing getting all of these features posted throughout the week. And we kind of blame tablets for the decline of the netbook industry (we still use a Dell Vostro A90 when not at home). But we’re trying to keep an … Read the rest
[Jay Kickliter] sent in his latest electronic business card. This time, his goal was to make it much cheaper so he could actually afford to give it away. He did pretty well considering the two week timeline he mentions. This card is using an MSP430 with the capsense library to light up some LEDs any time the card is … Read the rest
For over a hundred years, good typists didn’t ‘hunt and peck’ but instead relied on keeping their fingers on the home row. This technique relies on physical buttons, but with on-screen keyboards used on tablets and other touch screen devices touch typists have a very hard time. [Zach] is working on a new project to bring a chorded keyboard to … Read the rest
We’ve all had that sinking feeling as a piece of hardware stops responding and the nasty thought of “did I just brick this thing?” rockets to the front of our minds. [Florian Echtler] recently experienced this in extremis as his hacking on the University of Munich’s Microsoft Surface 2.0 left it unresponsive. He says this is an 8,000 Euro … Read the rest
This image should look familiar to regular readers. It’s a concept that [Chris Harrison] has been working on for a while, and this hardware upgrade uses equipment which which we’re all familiar.
The newest rendition, which is named the Omnitouch, uses a shoulder-mounted system for both input and output. The functionality is the same as his Skinput project, but … Read the rest
[Sprite_tm], a name many of you will recognize from these pages, has wasted no time in replicating the latest cool thing in a much simpler fashion. En Garde is a touch sensor that can detect up to 32 different points of contact on… whatever you use as the surface. He couldn’t sit idly by and let the Disney funded one … Read the rest
