    Giving a Raspberry Pi extra voltage is a quick way to squeeze out additional processing power and void its warranty, but the folks behind the tinker-friendly board have devised a turbo mode that boosts performance by roughly 50 percent while keeping warranties intact. After studying the effects of temperature and voltage on the hardware's lifespan, the team found that dynamic overclocking and overvolting doesn't affect the Pi's health appreciably. As a result, speeds can be pushed from 700MHz to 1GHz only when additional horsepower is needed, and things are reined back in when the CPU grazes 185 degrees Fahrenheit (85 degrees Celsius). Benchmarks show the extra computing oomph makes the Pi 52 percent faster on integer, 64 percent speedier on floating point and 55 percent snappier on memory tasks. The new mode is available in the latest firmware update, which also includes temperature and frequency widgets, better analog audio, improved USB performance and support for WiFi dongles out of the box.

    Though electronics hobbyists may not have the same resources that the Maker Sheds of the world have to design, package and sell do-it-yourself kits, electronics component distributor Jameco plans to change that. With Club Jameco, enthusiasts can pitch their kit ideas to the electronic component wizards in Belmont, CA and if a project is deemed viable for production, they'll be provided with feedback and have their idea posted for public comment. After the creation of step-by-step kit instructions, a list of materials and undergoing final approval, kits will be sold to the adoring masses. Once projects roll off production lines and into garages, creators will be paid royalties anywhere from five to ten percent based on quarterly sales. Aside from giving DIYers another sales avenue, it's also an opportunity for those who've been wary of piecing together projects to finally dive in sans the added fuss. Hankering to propose a bundle of your own? Per usual, all the particulars can be found in the source link below.

    Arduino boards have smoothed the creation of lots of eccentric thingamajigs, but robotics and controllers are still not for the faint of heart. Luckily, RoboMatter is coming to the rescue of would-be roboticists with a public beta version of its C-based RobotC language for Arduino. Joining Lego Mindstorm and other bots, Arduino will get RobotC's straightforward sensor and motor controls, along with a debugger and sample program library, while still keeping its native Wiring language. So, if you want to be a Kickstarter magnate , or just out-weird everyone else, rolling your own droid is now a bit easier.
