The Pocket-Sized Projector Has Arrived 220
mallumax writes "David Pogue of New York Times has reviewed the Pico, which is a pocket projector from Optoma. The review is quite entertaining (Pogue projects the images on to a plane's ceiling, leaving passengers baffled) and detailed. The highlights are: It is a pocket-sized projector which runs on batteries and can project images and videos from a variety of sources like iPhone, iPod and DVD players with a 480x320px resolution, with a maximum screen size of 65 inches at 8.5 feet. It uses a non-replaceable 10,000 hour LED lamp and a DLP chip from Texas Instruments. The battery lasts for 90 minutes and can be recharged through USB or with its own power cord. The device weighs 115g and comes with an inbuilt speaker which is practically useless. If you want one, it will set you back by $430."

Huh... Didn't the thing use lasers... (Score:2)
The Pico I remember used laser diodes, not just a LED light.
The lasers allow much greater efficiency - traditional projectors, like LCD Monitors, actually use more energy to display black, because it has to activate the cells to block light.
In this case, the lasers just shut off, reducing power usage to what's actually needed to make the image, not to make a full while screen all the time.

That may be true in LCD shutter technologies, such as an LCD monitor. This baby uses DLP technology, which is essentially a chip covered in tiny steerable mirrors. To produce black, they simply aim the mirror off-screen. It costs essentially no more energy to produce black vs any other color.

Then gray must be even harder because it has to aim the mirrors back and forth rapidly.

I imagine the power costs of the DLP mirror chip to be negligible. Heck, even energy needed to black LCD cells isn't much compared to the backlight.
Not to mention that you're still throwing away, on average, over 50% of the light you're producing. While LEDs are more efficient that current generation lasers, it doesn't overcome that.
The projector I remember is both smaller(matchbox sized) and brighter.

Given that its a "10,000 hour LED" it should last over a year of continuous use. At 8 hours a day every day it will last 3 years.
At more realistic (but still high) levels of usage... say, 4 hours 4 times per week, we're looking at 12 years.
