The First Person Gamerunner fuses a treadmill with a USB game controller and allows players to literally walk through first person shooter games. The system uses optical encoders and embedded software to translate the movements of the treadmill to the corresponding movements inside the game environment, according to Charles Van Noland, Gamerunner's inventor. The toughest part of the design, he says, was translating digital signals from the encoder into the analog signals required to control the games. The system has a swiveling set of handlebars that allows players to make direction changes within the game. The handlebars also house user-configurable buttons, such as the one used for the trigger. Gamerunner Inc., the device's manufacturer, calibrates the system for fast walking speeds, rather than flat out running — mostly to allow gamers to play for long periods of time. And for the sake of safety, the treadmill moves forward only; a "reverse" button translates forward treadmill movement into backwards in-game movement. Gamerunner builds its treadmill structural elements from machined aluminum billets. "We wanted them to be rugged," says Van Noland, a mechanical engineer with a background in CNC machining.

The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
Barnacles and mussels stay attached to ship hulls and rocks because of a very sticky protein glue they secrete, holding on for a long time even underwater. Researchers at MIT took mussel glue as inspiration -- and as an ingredient -- for engineering their own sticky waterproof adhesive.
