Optoma PK-101 Pico projector

  • Print

Want to put on a show — on the fly — for your fellow dorm dwellers? Just slip Optoma's Pico projector out of your pocket and turn that blank wall in the lounge into an instant movie screen. About the size of a cell phone, the 4-oz. (113 g) PK-101 can project an image up to 60 in. (150 cm) in diameter, at a reasonably sharp (if far short of HD) resolution of 480 pixels by 320 pixels, and it even has a tiny built-in speaker. The diminutive, battery-powered projector comes with an iPod/iPhone-compatible cable and will also work with any DVD player or digital camera with standard RCA-style video and audio plugs. No, the PK-101 will never compete with an IMAX theater, but it's better than trying to watch The Lord of the Rings on a 3-in. iPhone screen.

Price: $299
