Researchers at the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz led by Prof. Dr. Reinhard Baumann have unveiled tiny, printable batteries that they hope to put into production for pennies apiece. The new battery prototype is primarily composed of a zinc anode and a manganese cathode that can be screen printed and covered with a non-printed template cover. Each mercu...

Lovers of pyrotechnics everywhere have always struggled with the quandary: what to do on a rainy day? Well, firebugs, get a load of this: Sega Toys Japan has heard your prayers and answered 'em in the form of the Uchiage Hanabi. This is essentially a projector that displays "fireworks" on the walls and ceilings, with realistic movement and sound. And if that weren't enough, you can creat...

Uh, oh. Looks like there is something to take seriously about the reports that some are experiencing heat issues with the iPhone 3GS and the earlier iPhone 3G running the 3.0 OS. Apple has issued an Heat Advisory warning users that they could experience problems in an environment where temperatures exceed 95 degrees Fahrenheit and

CDM has a great post on the 30th birthday of the walkman. How excellent is that. Now I want one of those Akai 4-track walkman things again! var

So what if Thanko's ¥5,980 (about $62) Spy Button Camera doesn't look exactly like the other buttons on your shirt. Anyone inclined to wear such a device to covertly record VGA video at 15fps (or 1280x1024 stills) to 4GB of internal memory isn't likely to get noticed in a crowd anyway. At least the magnetic on/off switch gives renewed purpose to your wedding ring while offering...

But to fully understand why, you have to go back and look under AdWords' hood. How 22% Annual Fees For You Equals 51% Operating Margins For Oracle And finally, will customers who've spent the past 12 mon...

Looks like Verizon's got a winner here. That leaked promotional graphic was right on the money, as the carrier's just replaced its BlackBerry Tour teaser with a pre-order page and, lo and behold, it's indeed coming July 12th for a penny under $200. We're still waiting to see if Sprint's whispered July 20th date pans out, but regardless, if you want a Tour before anyone els...

What's this? An as of yet unannounced Nikon D3000 camera has allegedly popped up in press photo format, flaunting itself as what appears to be a slimmed down entry level DSLR. The gang LensTip have analyzed the pic pretty thoroughly against the D5000 and have concluded it's got a smaller body, no HDMI connector, no microphone (so much for a movie mode), and likely no articulating display...

One of our favorite intellectual property rips of recent months is without a doubt the SciPhone Dream G2 from China. Having completely missed the point of Google's open-source OS being, well, open-source and thus free for SciPhone's use, the company instead chose to hack the G2's "proprietory" OS to look like Android. The charger, however, built to look like the iconic Android masco...
