Alkaline Charger, Gigabit Powerline, And Tiny 802.11n

Computex 2010 Roundup: Coverage From The Show Floor
By , Dmitry Chekanov

Specialty DRAM chip vendor Etron Technology said it is sampling a USB 3.0 host controller developed in-house that it intends to sell to motherboard manufacturers, with mass availability slated for the third quarter of 2010. We saw a sample board with this controller at the show, but couldn’t perform any tests. Choice is a good thing, though. Hopefully, we'll have a number of USB 3.0 controllers from which to choose soon.

What do you think about recharging common alkaline batteries? Crazy idea, right? How about potential damage to your charging device? Of course. But GreEnergy was at the show showing off its own patented alkaline battery charger. It supports AA and AAA alkaline/NiMH/NiCd batteries. As for alkaline batteries, charging time is about four hours, and you can charge one battery up to 20 times. We think this is a cool idea, and quite possibly easy to make worth a $20 asking price if it does its job well.

Two models are currently available. The CT-515 (in the photo above) will work from electrical socket (100-240V) and can recharge four batteries with 350 mA maximum current. The CT-586 will work from USB (5V/500 mA) and can charge two batteries with 300 mA maximum current.

We don't know how much truth there is in the company's representatives' words, but we will definitely test this charger in future.

We were amazed by this tiny USB-based 802.11n adapter from Micronet (the SP907NS). It's probably very easy to lose, so be careful. The adapter supports the 802.11b/g/n standards (single transmitter, single receiver), WPA2 encryption, WPS, and transfer rates of up to 150 Mb/s.

ST&T was showing off a prototype of its Powerline adapter, which can achieve speed up to 1 Gb/s. That's a nice boost from the technology's usual 200 Mb/s. Additional details are not available, so we'll have to wait for more information on this one.
