Under the Hood: Mature devices get Rolly rocking
The Sony Rolly, shown at the Consumer Electronics Show in January, is a "dancing" MP3 player: When songs are loaded or streamed via Bluetooth, the Rolly can roll around and flap its speaker coverings in time with the music. The speaker flaps can also muffle the sound and give it a bit more flare when noise is channeled through one side or the other.
Under the Hood: Surveillance on a shoestring
A recent run-through of my local Fry's Electronics was stretched a bit when I took a walk down the do-it-yourself security aisle. Among an array of products for those wanting self-serve video monitoring, a $99.99 surveillance kit caught my eye.
Under the Hood: Inside Sony's OLED TV
For its XEL-1, the first commercial OLED TV, Sony made some interesting design and component choices to realize an 11-inch-diagonal screen that is only 3 mm thick. See what devices make up this ground-breaking display that is a harbinger of exciting times ahead.
