Dash cam

We've all had it happen while out walking, cycling or driving. Somebody does something foolish and it results in an accident or a near miss, a giant meteor comes streaking through the sky or we catch a rare glimpse of a hoverbike-riding robot. Something memorable always happens when your phone is cached safely in your pocket. This typically leaves you shaking your fist at the missed opportunity.

Victim of road rage? An accident? Ever had your car dinged while parked in a public lot? These are all great reasons to invest in a dash cam. And with prices for decent units at well under a hundred bucks, the cost of admission is easy for just about any budget. While the technology may not appeal to everyone, the payoff in the unfortunate event of an accident might just make it a must-have. So if you're in the market for a dash cam or you're just plain curious what they're for, here's what you need to know.

No one wants the smartwatch category to succeed more than I do. As a kid, I dreamed of enjoying TV on my watch, or video calling "HQ" (or more likely, my mum), just like Penny in Inspector Gadget. Most smartwatches offer a taste of this experience, but not the whole enchilada. Enter Neptune Pine. It's a smartwatch by the loosest definition: it's a small Android phone in a wrist-strap. Whatever you want to call it, it'll do both of the above things, and more. It's also a genuine Kickstarter success story -- like, one, where the product came out and everything! It might not be the first smartwatch/phone mash-up, and it's (definitely) not the last. But, it's one of the more ambitious takes on the idea I've seen. I spent seven days with it (and no other phone) to see how my dream stands up to the reality -- and whether a watch could ever replace your trusty mobile. The galleries tell much of the story, so be sure to jump in when you see them.

I'm not complaining about my life, but one of the downsides of international travel is that it's an in-and-out process. That means I land, scratch together a few hours of fitful sleep and then dive head-first into the breakneck pace of covering a trade show. By the time I've adapted to a new time zone, it's time to pack up and go home. That's why an app called Entrain from the University of Michigan was such an exciting prospect, since it promised to help my circadian rhythms resume normal operation in record time and hopefully make those first few days a little less painful

It's been a bright summer for solar energy -- Samoa just cut the ribbon on the largest solar array in the South Pacific, and even Saudi Arabia -- the country with one of the largest oil reserves in the world -- is investing heavily in photovoltaic technology. We also showcased an awesome energy-generating briefcase that lets you carry solar power everywhere you go! In other renewable energy news, Seoul, Korea, is planning to install new hydro-powered charging stations so that residents can keep their mobile devices charged. The city will install mini hydroelectric turbines embedded in the Cheonggyecheon River, which runs through the capital's downtown. And a town in Denmark just unveiled an amazing Energy Tower that transforms trash into electricity!

Broken Hard Disk

Saving files to memory is something that's supposed to be mostly invisible for the end user. We don't need to think about it; it just has to work. But whether it's a solid-state or hard disk drive, conventional storage solutions have their limitations -- namely, speed, rewritability and durability. A team at IBM Research's Almaden facility in California has a cure for all of that and it's called "racetrack memory."

Mobile technology continues to expand and evolve, but until we develop a way to charge our devices on the go, we'll continue to jockey for outlets at airports and coffee shops. Enter Angelo Casimiro, a 15-year-old who has developed a shoe that harnesses the power of footsteps to charge your phone. The youth of today continue to be at the forefront of renewable energy innovation; a 14-year-old named Gregory Martin recently made a major biofuel breakthrough with a technique that boosts the amount of lipids in algae by over 500 percent.

There are times when I just want to lie in bed and surf random YouTube channels on my phone or tablet, but it's impossible to hold the device above my head for a prolonged period (we've all been there, right?).

Luckily, I stumbled upon this neat kit in Shenzhen one day: a swing-arm tablet holder by some random brand called Usiabu, and it only cost me CN¥80 or $13, as it was from a wholesale dealer (retail price is around $25 in Hong Kong, and Amazon's start from around $30). As you can tell from the price, this product doesn't involve any groundbreaking technology: you've probably already come across desk lamps that use this type of spring-loaded mechanism.

MeMO Pad 7 and 8

A few years ago, tablets were poised to replace laptops as the computing device of choice. That never happened, as we've largely stuck with laptops and phones as our daily drivers, with tablets relegated to a secondary role. If you don't use a tablet that much, it certainly seems wise to avoid dropping a lot of cash on one. But a lower price often means compromises, and too many compromises means you won't be using the tablet at all. To figure out how many corners you can cut when it comes to purchasing a sub-$200 tablet, we've gathered opinions from across the web, from our own reviews to the opinions of other trusted critics. Which cheap tablets balance performance and price to still deliver a good experience? When is it worth spending just a little bit more money? And which deals are too good to be true?

Casio continues to inch its G-Shock series toward something a little smarter, while holding onto a simple monochrome LCD display and that distinctly G-Shock styling. The "G'Mix" GBA-400 improves on the typical digital watch feature list through Bluetooth, a pair of dedicated apps (one for the watch part, one for the music-playing part) and your smartphone, whether it's iOS or Android. Oh and there's a giant dial control on the side and it's really satisfying to play with.
