SUMPOD printer has the looks

Check out this fine looking 3d printer from Richard Sum.

The aptly named SUMPOD is currently the focus of an IndieGoGO campaign, where contributors can pledge their support and receive the sum of many parts in return.

It’s interesting to note that Richard has based his printer off the RepRap (as many 3d printers are these days, for good reason!) but has given it a refined visual language that is unusual in the DIY landscape. Exploring beyond the smooth white exterior, the SUMPOD has a build area of 150×150x100mm (a little bigger than the Makerbot) and an overall footprint of 280×350x280mm.

Benelli High Technology – Computer Modeling and High Speed Video

An example of how the latest in technology has found its way into the firearm industry is Benelli’s design bureau. The engineers there utilize various CAD software programs, as well as a high speed camera capable of taking 1 million frames per second, to design, test, and analyze their weapons. One of the more interesting things we saw at Benelli was what you’re about to see in this video: high speed camera footage alongside a computer model in motion.

Some of this same technology is in use by automotive racing teams at the highest levels of competition, to squeeze every bit of performance out of their cars. Benelli’s goals are similar, and the knowledge derived from the use of this technology is part of the reason why their shotguns command high prices.

"Olha, Mâe! sem mãos!" Um conceito melhor que o Segway, na minha opinião...

TILTO is a home-built attempt at reinventing the Segway

By Pawel Piejko

Although it's not that uncommon to encounter people riding Segways, self-balancing vehicles haven't revolutionized urban transport as some expected. Created by Argentinean inventor Marcelo Fornaso, TILTO is a new incarnation of the idea behind the Segway. It replaces the stiff platform and wheels with tilting equivalents, while eliminating handlebars or a steering wheel. It is an electrically powered, single-person vehicle, with a maximum range of 15 km (9,32 miles) and top speed of 20 kph (12 mph).

TILTO (from "tilt and go") has no handlebars so turning TILTO is achieved by leaning sideways, which surprisingly is safer than turning a Segway, according to Fornaso. When turning a Segway at high speed, there are forces pushing the driver out of the vehicle. Turning by tilting reportedly eliminates this problem, since there's an inertial system that prevents the driver and vehicle from falling during turns. "It produces the left wheel to accelerate and the right wheel to decelerate proportionally," Fornaso says.
