For the gadget freak who thinks he has everything, here's Ed Nauman's microprocessor-controlled, pneumatic-actuated can crusher. Great for parties, it consists of a pneumatic ram, precision bore crushing cylinder with aluminum crushing piston, two pneumatic rams to control the loading of cans, and solenoid valves to control the rams.
Operationally, the user simply loads the cans into the magazine, opens the pneumatic ball valve to charge the surge tank, places the rotary mode switch in either auto or manual, and presses the run switch. In full auto mode, the crusher loads and crushes cans at the blinding rate of 1.5 cans/second. That's a lot of six packs!

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
