Logitec Japan (not Logitech) has released the world’s smallest stereo Bluetooth 2.1+EDR earphones. The LBT-PCHP02 series is designed for PC users, while the LBT-AVHP02 series is designed for your portable audio player needs.

Both have batteries that deliver four hours of playback and measure just 1.3-inches long and 0.23 inches thick. You’ll get several earbud sizes included so it should fit you with no problems. These earphones can also support two different Bluetooth sources at the same time, so you’ll be able to connect it to your media player and phone.

Amex Digital’s latest is the smallest media player to actually handle 1080p. The device measures just 175- x 128- x 15mm and weighs just 250 grams. The player can accept a range of file formats from a connected USB storage device or an SD card.

It will also output 1080p over HDMI, and there’s a composite video / audio output and mini-USB port in the back. The MP-501 is equipped with an ARM Cortex-A8 processor and will play nice with nearly every file. The best news is that it is just $49.

We’ve seen our share of pocket-sized speed radar detectors, but the new Pocket Radar might be the first that could actually fit in your pocket. Or in the palm of your hand. Of course there are some trade-offs for the size.

Still, the company says that it “forges a new standard in speed radar performance,” and supposedly it can track the speed of everything from a fastball to race car within one mile per hour. We can only take their word for it.

There is an unseen world, filled with tiny things which resides in our own. It just got a little more festive. Scientists at the National Physical Laboratory have built the world’s smallest snowman. And they didn’t create it using balls of snow.

Instead they used two tiny beads. Beads typically used by physicists to calibrate electron microscope lenses. The pieces were welded together with platinum. It measures just 0.01mm (1/5 the width of human hair). It’s the result of manipulation of nanotech particles.

Epson is claiming another first with this world’s smallest LCD panel and they’ve started volume production of these tiny guys. The XGA HTPS-TFT Liquid Crystal Panel was specially designed for 3LCD data projectors and are up to 23% smaller in size than its predecessor, using a 0.55″ display panel.

The tiny panel can display a natural XGA (1,024 x 768) resolution, targeting projectors which can display up to 2600 ANSI lumens. Epson isn’t resting easy with this achievement though. They even have plans to push the envelope to create higher resolutions for the panels.

Getting video on a small screen is not a huge thing and it’s not new. But how about video on a screen that’s insanely small? Kopin has managed to pack a liquid-crystal display (LCD) with VGA resolution (600 x 480 pixels) onto a screen that measures just over a quarter-inch diagonally. To put that into perspective, that means that the individual color dots are 2.9 x 8.7 micrometers. A typical piece for paper is about 100 micrometers thick.

So who is going to use such a tiny screen? Who is this screen for? Kopin thinks the new screen is a stepping stone on the way to creating a screen with 2,048 x 2,048-pixel resolution the size of a postage stamp. Great HD quality…If you are an ant.

Though it likely won’t hold the title for long, Earth Trek has christened their new 90-805R projector the “world’s smallest”. It measures roughly 4 inches X 2 inches.

The device will give you a 22-inch diagonal image, though I have no idea from what distance. It sports an SD card slot and a 3.5 mm jack A/V input, built-in lithium battery good for 1-2 hours, MP4 player and built-in speaker. Nothing on price or a date yet, but expect it very soon. Not much else to see here, move along.
