Optoma PK-101 Pocket Projector Preview Monday, December 08, 2008 - Iddo Genuth Home >> News >> Gadgets

The Taiwanese manufacturer Optoma recently introduced a new pocket projector called PK-101. The tiny device, no larger than an iPhone, can project an image up to 60 inches in size from a distance of about two meters and could be used to project still images, videos, and presentations. TFOT recently had a chance to spend some time with the new projector which is also one of the first commercial pocket projectors currently available on the market.

The PICO pocket projector uses DLP technology; DLP projectors use a special optical semiconductor called a Digital Micro-mirror Device (DMD), which was invented in 1987 by Texas Instruments. It is a precise light switch that enables light to be modulated digitally via millions of microscopic mirrors. The mirrors are capable of switching on and off thousands of times per second and are used to create a picture comprised of millions of pixels. With the PK-101 Optoma was able to miniaturize the entire projecting system to a tiny size while still keeping a (fairly) reasonable brightness.
The unit has a declared contrast of 1:000 and the LED lamp it uses is said to last up to 20,000 hours; conventional high-end projector lamps typically last only about 3000-5000 hours before they need to be replaced. The LED lamp is rated at about 9 ANSI lumens, a ridiculously low number compared to some of the company’s full size projectors, which can reach up to 5000 ANSI lumens. We shall get to the actual performance of the projector in a moment but it’s also worth noting that unlike conventional projectors the PICO is completely passive with no moving parts; in fact, during the day the pocket projector fell on the carpet floor several times with no apparent damage.
In a darkened room the Optoma projector was able to display a fairly bright 50-60 inch picture. This is by no means something you would want to use for your high-end home cinema system, but for the occasional outdoor family trip or for the road warrior who lives and breathes presentations, the PICO projector could very well be a useful little device. Optoma is also unsure what sort of applications the new projector might eventually find. Adam mentioned several possible uses for the PK-101, including as an in-car projector, or as a portable projector for gaming (SG actually showcased a Sony PlayStation 3 connected to the PK-101). Another possible use mentioned by Adam was watching movies during flights, although it would probably be more sensible for the airline companies themselves to integrate the tiny projectors to replace the small LCD screens currently in use in many airliners. Adam concluded by saying: “In terms of the uses that users will find for the PICO, we are confident that users will not need much prompting to use the PICO in a wide range of settings. We have delivered a flexible product that is capable of delivering high quality output in most environments. With the flexible connectivity, it will interface with an extremely wide range of devices.”
The PK-101 has only one bottom with three positions – full brightness, off, and reduced brightness, which is used to reserve battery life (it should add about 20% more to the battery life). The device itself is true plug and play with no menus or configurations of any sort.
One of the less appealing aspects of the PK-101 is its low resolution. At 480 x 320 (half VGA) the projector is perfectly O.K. for watching standard resolution videos but it might not be as good for reading small text and might prove to cause problems when trying to connect the unit to a laptop, something we intend to test in our upcoming full review of the PK-101.
The street price for the PK-101 is currently just under $400.

this item was very hard to find in the USA, so I ordered one from Canada. My total cost with shipping was $501. the box arrived two weeks later, even though I paid for Express shipping. The projector was supposed to be the North American version as promised by the seller, Shark Systems. I called them before ordering. I had a prior conversation with Optoma wherein I learned about two versions of this product...one for Europe/Asia and another for North America (US). The US version is supposed to include an iPod cable as well as a volume control cable. My projector arrived without an iPod cable and the volume control was missing too. I phoned Shark Systems and they instructed me to contact Optoma. My emails to Optoma direct me to the seller for the missing parts, even though it was brand new in a sealed box. Hmmm? I took it out of the box, charged the battery and fired it up. Since the iPod cable was missing, I had to connect my 120GB iPod Classic via the lo-res composite cables (red/white/yellow). I played several minutes of "Goya's Ghost" and "Into The Wild". I chose these two movies because Goyas Ghost has a lot of dark & black scenes while Into The Wild has a lot of bright white scenes. Sadly, it didn't matter because the predominant hues (tints) were a bluish-green caste. I switched the source to a COBY portable DVD player with Dark Knight and Planet Earth via lo-res composite cables included. Again, the whites looked greenish while the blacks looked blue. The screens that I projected onto were a Da-Lite and also a 30" Nuvi. Then, I tried projecting onto different flat surfaces around the house and the most impressive in terms of color, contrast & sharpness was the side of my white refrigerator. I played Led Zeppelin's "The Song Remains The Same" on the side of my refrig and it looked nearly true! Odd...I know.. So, all in all as the first reviewer...I gotta warn, don't waste your money unless you really wanna impress friends/family with "cutting edge" tech. Truly, the image quality was a 2 out of 10 and the customer support was even worse. One final note, the iPod cable only works for Video iPods that are older like Gen 5, Gen 4...it will not work with 80GB/120GB/160GB Classic! This info is found in the manual, the photos on Optoma's website are misleading. I have placed my PK-101 on eBay for sale...I will continue to use my Cinego D-1000 |
