Hasta La Gadget!

In this day and age, we all carry our fair share of gadgets wherever we go – and one important aspect of this would be to ensure that our gadgets remain fully charged so that we will not be caught unawares when the situation arises and we need to make that all important phone call or send an email. With the $149.99 PowerPot Thermoelectric Generator, it is one device that will be able to take heat and turn it into power, which would then be able to juice up any USB device using a heat source.

The PowerPot Thermoelectric Generator has a 5W output, and is the perfect companion for backpackers, hunters, and basically those who do not mind roughing it out in the wild for a few days on end without a single power outlet in sight. Definitely the perfect addition to any emergency kit, and just in case you are worried that your plugged in device might actually burst into flames, fret not, as the cord is flame-resistant by itself, and is said to be able to chrage just as fast as it does from a standard outlet.

It looks dangerous—because it is—but there’s more to fire breathing than meets the eye. In order to do it safely, you need to think about the science involved, and this video explains why.

Remember LG’s EA93, that eye-catching 29-inch 21:9 “ultrawidescreen” monitor we played with at IFA last year? Well, it’s just spawned a couple offspring. Today in Korea, the company launched a TV set and an all-in-one PC which use the same 29-inch IPS panel with the same 21:9 aspect ratio, 2,560 x 1,080-pixel (WQHD) resolution and 178-degree viewing angles.

LG’s new all-in-one PC boasts a standalone TV tuner with instant-on (no booting required) and simultaneous PC and TV operation (PiP and several split screen modes). Details are few, but we know it features an Intel Core i5 CPU, NVIDIA GeForce GT640M GPU (3D capable) and HDMI / MHL inputs (to use the display as a monitor). The PC comes pre-loaded with an instant messaging app (and matching mobile version) which lets users watch television while chatting.

The TV set supports PiP and split screen, including a 16:9 plus 5:9 mode (HD broadcast plus connected smartphone), and offers a comprehensive set of inputs (DisplayPort, DVI, HDMI and MHL). Pricing is 1.49 to 2.29 million won ($1,315 to $2,021) for the PC (based on configuration) and 690,000 won ($609) for the TV.

Mercedes aims to have its cars talking with each other and warning drivers of potential hazards ahead by the end of the year, with the company the first to deliver Car-to-X wireless to its range. Described as giving drivers the ability to “see around corners”, Car-to-X allows vehicles to send out localized warnings and notifications

Anyone who’s tried to tether to their iPhone or iPad will recall how iOS manages to craft its own passwords when used as a personal hotspot. The aim is to ensure that anyone sharing a data connection will get some degree of security, regardless of whether or not they tinker with the password themselves. However, three researchers from FAU in Germany have now worked the structure behind these auto-generated keys — a combination of a short English word and a series or random numbers — and managed to crack that hotspot protection in under a minute. To start, the word list contains about 52,500 entries, and once the testers were able to capture a WiFi connection, they used an AMD Radeon HD 6990 GPU to cycle through all those words with number codes, taking just under 50 minutes to crack with rote entry. Following that, they realized that only a small subset (just 1,842) of the word list was being used.

With an even faster GPU — a cluster of four AMD Radeon HD 7970s — they got the hotspot password cracking time to 50 seconds. The Friedrich-Alexander University researchers added that unscrupulous types could use comparable processing power through cloud computing. “System-generated passwords should be reasonably long, and should use a reasonably large character set. Consequently, hotspot passwords should be composed of completely random sequences of letters, numbers, and special characters,” says the report, which outlines the trade-off between security and usability. However, as ZDNet notes, Apple’s cycled password approach still offers more protection than static options found elsewhere. Check out the full paper at the source.
