Tiny Tech Gadgets

It's a teeny camcorder, DVR, hidden webcam, and camera ($16) all in one. And it actually works — you know, if you don't crush it while you try to take a snap.

Not just for kid fingers. At two inches wide and almost three ounces in weight, this Game Boy Micro ($170) was discontinued in 2008, but lucky for you, you can still get it on Amazon.

Yes, that's a minispeaker ($10) that fits on your fingertip, and it only weighs 17 grams. Seventeen grams! But it promises to bump your tunes just as well as any other speaker.

Is this the world's smallest walkie talkie ($15)? That's what it claims to be, and while we may never know for sure, it definitely looks like it. Just think of all the microcommunication that awaits.

It calls itself the world's smallest USB 3.0 flash drive ($96), and it's hard to challenge that claim. Just look at the teeny thing! If you didn't think it could do more than hold 64GB of data, you're wrong — it also comes with a small LED activity light.

So you could buy a mini, dorm-size fridge (already a feat of miniaturization wonder), but why bother with all that wasted cubic feet when all you're going to be storing is the twice-daily Diet Coke? The answer is this USB LED cooler ($15, originally $30), which plugs into a computer to chill one beverage at a time.
