Fresh hacks every day
We always enjoy seeing what Electrical and Computer Engineering students dream up for their final projects, and though we must have missed this back in 2010 when it was published, [Bruce Land] dropped us a line to bring our attention to this cool Haptic Exercise Coach. Designed and built by Cornell students [Michael Lyons] and [Greg Meess], the Haptic Exercise Coach is a small electrical … [Read more...]
We never imagined that [David Lee Roth] would mesh well with an Arduino, that is until Flickr user [tgtsfkncld] showed off his [Roth] Scream Box a few days ago. The unassuming box resembles sort of a nondescript “Easy Button”, but its payload is far more entertaining than whatever Staples could have possibly recorded for their device. Once the Scream Box is powered on, each press of the … [Read more...]
Sometimes, an Arduino just doesn't have enough horsepower. Whether you're gathering loads of sensor data and sending it over the web via Ethernet, or just trying to build a home-brew video game, it's very easy to run into the limitations of the Arduino platform. [Rik] and his fellow classmates may have a solution to this problem with their SimpleCortex development board. The SimpleCortex began … [Read more...]
For [Gunnar]'s diploma thesis, he wanted to build an autonomous bicycle. There's an obvious problem with this idea, though: how, exactly does a robotic bicycle stand upright? His solution to balancing the bicycle was a reaction wheel that keeps the bicycle upright at all times. A bicycle is basically an inverted pendulum; something we've seen controlled in a number of projects. To balance … [Read more...]
The decision to use electronics for our calculating machines has long been decided. However, that doesn't mean that mechanical engineers didn't put up a valiant, if ultimately futile, fight. [Dvice.com] has an interesting article comparing the calculating technology of the 1960s, such as the [Haman 505], to today's iPad. This comparison and pictures were made possible by [Mark Glusker]'s … [Read more...]
