While working on a project for a television program,
several-times-over Gadget Freak John Tindall started tinkering with a pulsejet
engine. Pulsejet engines were used by the Germans during WWII. The technology was
left behind by turbofan jets. But Tindall found the pulsejet well-suited to garage
- and Gadget Freak - tinkering. Apparently there is a wide community of
hobbyists playing with pulsejets at home. Tindall came up with a cyclonic-valve
radial design that makes for smoother airflow. He proved the concept with
plastic and aluminum valves - but the gadget backfired and blew up. Next step, a
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
