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.

United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
