When it comes to tech gadgets as holiday gifts, the familiar is always popular.

Apple iPads. Samsung Galaxys. Eighty-four-inch LED TVs with a 3-D, 4K ultra-high definition picture, four built-in speakers and smartphone control.

OK, so that last one might be a little pricey. (It would also be popular.)

Still, you almost certainly know about the new iPad Air. You probably also know about the new PS4 and Xbox One gaming consoles.

But have you considered a portable solar array? Or some electric paint? Or a camera that creates a visual diary of your life?

Take a glance at our holiday gift gallery, above. We hope it offers some interesting ideas that go beyond the usual roundups of phones and tablets.

And if you have some ideas of your own, let us know in the comments. We'll be checking them twice. (Prices listed are full retail, but you can probably do better.)
