Smartphones and tablets are convenient ways for consumers to enjoy music
on-the-go, but they have limits for audio reproduction – the internal
hardware is able to accomplish only so much. Portable digital-to-analog
converters (DACs) and AMP products solve this by providing the necessary
power, but most options tend to be bulky, battery-operated, expensive,
or all of the above. The Nexum Aqua aims to deliver an audio experience
without any of those drawbacks.
Occasionally an invention comes along that promises to change mankind fundamentally, enable us to grow as a species, and expand our capabilities beyond what was previously thought possible. MagKey isn't one of those kinds of inventions at all. It simply uses magnets to stop keys from jangling, but we're still impressed.
Above all else, it's important that any device does its bread-and-butter functionality well. The nipi cooler, which is currently the subject of a Kickstarter crowdfunding campaign, is said to keep ice frozen for six full days, and comes packed with what its makers are calling "21st century survival features."
Smog affects many major cities around the world and can cause health problems for those breathing it in. To highlight this issue, Dutch artist Daan Roosegaarde is building what he calls the world's largest air purifier. The Smog Free Tower is designed to allow people to breathe clean air in a city ... plus it also turns the smog into jewelry.
For those that like to mix and match their jewelry to match their outfits, Covair is looking to make what it calls classic timepieces with interchangeable components. This means you can swap the face or strap out for another whenever and wherever style dictates or the mood strikes you.
Bicycle generators always seem like a good idea, but the friction caused by an old-fashioned pedal-powered dynamo can be a drag – literally. Miami-based startup Spinetics says its new CydeKick Pro generator can turn your pedal power into electricity for charging a phone and running a headlight without adding any friction.
While hub motors may be quite common on commuter e-bikes, they’re not so popular on full-suspension electric mountain bikes. That’s because they add unsprung weight, which nobody wants. Various companies have responded by developing motors that are located in the middle of the bike, near the bottom bracket. These solve part of the problem, although they have to actually be built into the frame. That’s why Germany’s Bionicon has created the e-ram – it’s reportedly the world’s lightest mid-mount motor, and it could potentially be installed on existing mountain bikes.
While many people may like the "pop-in-your-mouth" texture of caviar,
not everyone likes the taste ... or the price. That's why Montreal
entrepreneur Naor Cohen created the grandly-named Imperial
Spherificator. It takes a liquid of your choice, and converts it into
fish egg-like pearls. Sriracha caviar, anyone?
When it comes to hanging things on a wall in a straight line, a laser level can go a long way towards making that easier to accomplish. A new device called Sure Hang aims to make the laser level even more useful by allowing it to integrate directly with a tape measure for hanging things up at a perfect interval along a level, straight line.
If you've ever wanted to channel your inner Buckminster Fuller and
construct a geodesic dome but didn't know how, you may well be in luck.
hubs promises to make building an open geodesic dome quick and easy,
with construction time rated as under an hour. Its creators cite
possible uses for the dome as a garden room, aviary, chicken run,
children's den, and more.
