Chinavasion “MiniView” LED Projector…

If you’re budget sensitive and really want a mobile pico projector, the latest Miniview LED projector from Chinavasion may be a fit. The main features that it boasts is having a variety of input connections and its mobility.

budget video projectorThe MiniView does not have batteries and does requires a power cord to plugged in to work. Shinning with a 55 ASNI Lumens this project has a price tag of $69.91.

“With an 100 inch wide projection, 200: 1 contrast and 1.67 million color projection the Miniview is a high performing video projector,” says Rose Li, PR manager for the projector specialist.

While this may not be the brightest in the bunch it has been doing surprisingly well in the market. One of its key features to talk about is the coaxial input allowing the user to connect their cable or satellite feeds directly into the projector.

Here is the list of inputs:

1 x Antenna
1 x Micro SD Card Slot
1 x USB
1 x HDMI
1 x VGA D-Sub 15pin
1 x Composite
1 x EF

So the question you have to ask yourself is if the MiniView’s functionality and low price outweigh a competitor’s brighter display, higher price, and in some cases better mobility (battery powered)?

Carnegie Mellon Researchers Reduce Headlight Glare through Projectors

 

Researchers at Carnegie Mellon University say they’re working on a solution that could make raindrops nearly invisible while lighting the road in front of you.

The problem Carnegie researchers are trying to solve is that headlight beams are reflected back at the driver when it rains, snows, sleets, et cetera. The brighter your headlights, the brighter the light is reflected back at you, and the harder it is to see the road ahead of you.

Carnegie’s researchers came up with a possible solution involves a camera, a digital light processing (DLP) projector, and a reflecting mirror, alongwith a computer to control the whole setup. As rain falls, the camera can detect individual raindrops and predict their velocity and trajectory. It sends that information to the projector, which projects a small black dot over each rain drop’s location. The result, researchers hope, is the ability to light in front of the car but not the raindrops, which would result in the most light output without returned glare.

As expected, it’s very difficult to detect individual raindrops and light around them. The system takes about 13 milliseconds to find raindrops and respond accordingly, so the top portion of the light beam would still hit the raindrops like a standard headlight. As it stands today, the system also works best at a speed of about 19 mph, where it’s 68.9 percent accurate at blacking out raindrops while still keeping over 95 percent light throughput. Drive faster and the system steadily loses accuracy. As you can see, it still is a ways off from mainstream implementation.

As we always say with futuristic tech like this, it’s going to be many years until we see something commercially viable that works like this. The system will need some big strides in digital light processing projector technology to work better,

Still, the idea of going from halogen bulbs to xenon to LED to DLP projector headlights is intriguing, and having two DLP projectors and two wide-angle cameras mounted to the front of your car would open up a whole new world of active headlights that could shift to avoid blinding oncoming traffic or pedestrians.

Who knows, maybe eventually we can project movies from those headlights.

 

 

AAXA releases M1 Ultimate-X LED Projector

AAXA Technologies has released the M1 Ultimate-X led projector. The only difference between the Ultimate and Ultimate-X is that the Ultimate-X features a 2GB SD Card instead of 1GB onboard memory. The reason AAXA has choosen to go this route is to further increase the stability of the onboard operating system.

For those unfamiliar with the M1 Ultimate here are some specs:

* Native SVGA (800×600) resolution
* Ultra-bright 75 lumen LED light source
* SD card reader – 2GB card included
* NEW aluminum case, touchpad, and tripod
* Excellent text clarity and contrast
* Input support: See technical info below
* RMVB, MP3, AVI, JPG decoder
* Projects up to a 100″ image*
*(In low-light conditions)
* Optional iPod, PSP, PDA, DVD input cables
