Using a hand saw is nobody’s idea of a good time, but one inventor is trying to at least make it a little easier. John Zimmerman, a software developer by trade, has created what he calls the Recoil Saw. Essentially, it’s just a saw – various types of saws, actually – with one or more spring-loaded impact bars attached to the blade. At the end of each stroke, the spring compresses as the bar hits the material being sawed, then releases that energy back into the following return stroke. The idea is that users can pretty much just bounce their way through cutting jobs, as opposed to having to purposefully stop and start between every stroke. Zimmerman, who admits he’s probably not the most unbiased tester, said that he has found it cuts twice as fast as a regular saw. Read More

Dr. Douglas Engelbart is perhaps best known as the inventor of the computer mouse, but when he unveiled that device at a computer conference in 1968 he also introduced additional technology that would profoundly affect computer-human interaction as much as the mouse has. During the "mother of all demos" at the Fall Joint Computer Conference held at the Convention Center in San Francisco, Engelbart and his team of researchers from the Augmentation Research Center at Stanford Research Institute gave a live demonstration of hyperlinks, remote collaboration software, on-screen windows, and even video conferencing.

Charles Babbage was the quintessential "man ahead of his time". In the mid 19th century the English mathematician and inventor developed the concept of a programmable computer and designed complex, steam-powered calculating engines that were never completed during his lifetime. One of these machines – the Difference Engine – was successfully constructed using Babbage's original plans in 1991 and now programmer John Graham-Cumming is on a mission to build a working replica of a second, more complex computing machine known as the Analytical Engine.

Perhaps you haven’t given this problem a lot of thought, but it is a problem nonetheless... most spray bottles can’t be used upside down, or even at much of angle once they’re half-empty. Not only that, but there’s always that last little bit of liquid in the bottom that gets wasted. That's because most of them have rigid-tubed sprayers that just have a single hole at the bottom, so they only suck up liquid from the bottom middle of the bottle. Well, British inventor Michael Pritchard has come up with something he calls the ANYWAY Spray, a tube that allows you to hold your spray bottles any way you darn well please, and keep spraying until they’re as dry as Keith Richards’ bourbon glass.

Ready for a bit of a mental mechanical challenge? Try your hand at understanding how the D-Drive works. Steve Durnin's ingenious new gearbox design is infinitely variable - that is, with your motor running at a constant speed, the D-Drive transmission can smoothly transition from top gear all the way through neutral and into reverse. It doesn't need a clutch, it doesn't use any friction drive components, and the power is always transmitted through strong, reliable gear teeth. In fact, it's a potential revolution in transmission technology - it could be pretty much the holy grail of gearboxes... If only it wasn't so diabolically hard to explain. We flew to Australia's Gold Coast to take a close look at the D-Drive - and it looks to us like Durnin has pulled a rabbit out of his hat. Check out the video after the jump and see if you can work out if there's a catch. Read More

Putting aside ugly flying cars, no one should fail to be moved by the gorgeous warm-colored wood, hammered copper trims and time-worn patina of this gorgeous piece of antiquity. One of the last known Curtiss MF Seagull Flying Boats is to be sold at auction on Tuesday April 13 at Bonhams in New York. Rich in history, this beautiful vintage sea plane was designed and created by engineer and aviator Glenn H. Curtiss, otherwise known as "the Father of Naval Aviation." Read More

Toilets use a lot of water. And once they’re done with that water, well, it’s very... used. So, any time anyone can suggest a way of limiting water usage in toilets, Mother Nature wants to hear about it. Recently, Australian inventors Tom Trainor and Mark Hutton came up with a product that they claim uses up to 90% less water than a regular toilet. The EVOLUTE’s patented new technology offers a greener, drier alternative to our current “swimming pool for your poop” model. Read More

Older Gizmag readers may remember the Etch A Sketch, a child’s doodling utensil that used aluminium powder and a glass screen to draw horizontal and vertical lines and the Magna Doodle, a similar product that used a magnetic drawing board. A cheap and cheerful version of the latter, often called the ‘magic slate’, consisted of a pad and stylus that allowed scribbles to be erased by lifting off and replacing a film of plastic. This concept has now been rather cleverly turned into a Mouse Pad called the Scratch-n-Scroll. Read More

The eniCycle is the latest entry in the increasingly crowded self-stabilizing electric unicycle market. Developed by Slovenian inventor Aleksander Polutnik, the eniCycle has Segway-like balancing capabilities but only a single wheel. With its three-hour battery and lean-to-go controls, this diminutive one-wheeler prototype brings Jetsons-type technology one step closer to reality. Read More
