Samsung’s SP-H03 pico projector is tiny. About the size of a hockey puck. But that doesn’t stop it from outputting 854×480 resolution with 1GB of internal memory in the palm of your hand.

The SP-H03 weighs only half a pound. Aside from the WVGA resolution, it boasts 30 lumen brightness, microSD memory expansion up to 16GB, and 1W stereo for your media presentations. It’ll be available this month for $300. Not bad at all for those specs in a projector this small.

The Uniden ULP1000 laser pico projector is capable of displaying WVGA (848 x 480) resolution pictures and videos with a 5000:1 of contrast ratio. The Uniden ULP1000 laser pico projector also comes equipped with a unique charging station instead of the simple power adapter.

When the device is fully charged, it delivers up to two hours of operation time, which is pretty average for pico projectors right now. The ULP1000 also has a VGA port and a composite port.

Another day, another pico-projector. This latest is a new model by RoyalTek, the RPJ-2000, all set to be the first of several from the company in 2010. The RPJ-2000 uses a second-gen 3M LCoS chipset and will project up to a 65-inch image with 14 lumens brightness and 640 x 480 resolution.

This one includes VGA and NTSC/PAL TV inputs, but there’s no integrated mediaplayer or onboard storage. They do throw in 0.5W stereo speakers and the RPJ-2000 is Apple-certified so you can use it with iPods and iPhones. You just have to add $43 for the adapter kit on top of the $315 price.

AAXA Technologies has unveiled their latest pico-projector dubbed the P2. It measures only 4.3-inch x 2.1-inch x 1-inch and weighs just 260 grams. The palm sized projector sports a 800 x 600 resolution, 33 lumens brightness, 1,000:1 contrast ratio, 1GB of storage, a microSD card slot and a 1,700mAh rechargeable battery that lasts up to 35 minutes.

It also comes complete with 1W stereo speakers, a 3.5mm composite A/V port, a mini USB port, a 3.5mm headphone jack and VGA port. The AAXA P2 is available now for pre-order for $349.

Surprisingly, it isn’t a huge name taking the Pico projector to 720p. Forever Plus gets the credit for the world’s smallest 720p projector. It measures just 0.49 x 0.59 x 0.19-inches and projects footage from HDMI at 1,280 x 768 resolution for 30,000 hours via LED lighting.

Nothing yet on price or availability. We’re not completely sold however. We’re a little skeptical that they didn’t list the brightness or contrast ratio. Makes you wonder why. They probably aren’t that good. Now the rest of the big names have to get in on the action.

WowWee is smart. They know that in this economy, it’s smart to diversify. We are all used to seeing the company’s latest robotics offerings, but now the company responsible for Tri-Bot is serving up a Cinemin line of micro Projectors.

Another thing of interest is the Spyball spy-cam, a remote controller, WiFi-enabled robotic ball. The company has more too. It doesn’t stop there. How about the Joebot and Roborover robots, FlyTech Lightstar flyer / Hoverpod racer, four brand new breeds of Alive Cubs and a fresh line of “pajama pals” called Sleeping Cuties.

When Moti Barzilay had to design something iconic in the Apple universe of products, something he felt was missing, the iShow was the end result. It’s a portable projector designed for Apple’s line of iPods, iPhones, and MacBooks.

The body turns on when you pull the two discs apart to reveal a pico projector and some ports. The projection system is LED based. Not very many details other then that, but since it’s a concept we can hope for HD resolution and the ability to roll itself around and take a charge by becoming a yo-yo and offering up some nice tricks with the string. That would be something to see Steve Jobs play with on stage.

We all love our tiny devices, but what we trade off is larger screen size when watching videos. Here’s a nice compromise. Optoma’s Pico projector. It’s currently in the prototype phase, but Optoma plans to have a limited release in Europe this summer, followed by international availability in 2009.

It’s a projector for your cellphone or iPod, and can be used on anything of course. Whether it’s on a wall or some fat guys back, this device will have you covered. Because you wouldn’t want to not be entertained for even like ten minutes. Then you might have to interact with others.
