USB Solar Power Bank Review

A few months ago, I won a $5 coupon for DealExtreme, and decided to buy a “Portable 5V (30,000mAh) Li-ion Battery Solar Power Bank w/ Dual USB + LED – Black + White” for just over $20. For the price, solar charging was a nice bonus, and the 30,000 mAh was probably a “mistake” but it did not really matter. The SKU is gone, but 1BA-2 Solar power bank ($23.97) appears to be a very similar product. I did not plan to write about this gadget, but a few things happened that made me change my mind. First. it took over two months to reach me, instead of the usual 2 to 4 weeks. I ordered on the 9th of November 2013, and received the package on the 25th of January 2014. The reason being that the package got declined by Thai immigration (I live in Thailand). DealExtreme could not […]

802.11ah Wi-Fi (900 MHz) to Provide Low Power, Long Range Connectivity for the Internet of Things

Most devices now feature Wi-Fi modules capable of handling 802.11 b/g/n at 2.4 Ghz (and 5 GHz for dual band Wi-Fi), and newer devices and routers boast 802.11ac connectivity @ 5GHz with increased bandwidth (up to 1.2 Gbit/s in theory, maybe around 400 Mbit/s in practive), and in some case increased range with  beam-forming. But thanks to an article on EETimes, I’ve learned there’s another upcoming Wi-Fi standard called 802.11ah operating in the 900MHz range, with data rates from 150 Kbit/s with a 1 MHz band to as much as 40 Mbit/s over an 8 MHz band, lower power consumption, and a least double of the range of a typical 802.11n device,capable of covering an area of about 1 km2. The target applications are sensors networks, backhaul networks for sensor and meter, and extended range Wi-Fi, as the standard allows long range and more clients at low bitrates. This new […]

Google’s Project Tango Phone Prototype Generates Real-time 3D Maps

Google ATAP (Advanced Technology and Products), the team who is currently working on Project Ara for Google, and recently moved from Motorola following the acquisition by Lenovo, has also been busy on another project called Tango, which centers around a phone equipped with cameras and sensors capturing 250,000 data points per second to track motion and generate 3D maps in real-time. The prototype is 5” phone with hardware and software customization designed to simultaneously track the 3D motion of the device, and creating a 3D map of the environment. The device runs Android and includes development APIs to provide position, orientation, and depth data to standard Java, C/C++ Android. This is still early development, but the team imagine the technology could be used to easily create a 3D map of your home, facilitating furniture shopping. Other usa cses include indoor navigations, visually-impaired aid, and product location in a store. Augmented reality […]
