Pocket Rocket

What are some of the biggest challenges using a projector? One of them is that fact that the lamp doesn't last very long and they are expensive to replace ($350, or more). Other challenges include weight, and warm-up and cool-down periods, and that you have to be close to an electrical outlet to use one.
Not any more. Mitsubishi Electric Presentation Products incorporates the latest LED (Light Emitting Diode) and DLP (Digital Light Projection) technology in their new one pound "PK-10 PocketProjector". The LED lights are rated to last up to 10,000 hours (in other words, you could use the projector for 3 hours every single day for over 9 years).

Because LED lights use the least amount of energy for light produced of any other source, Mitsubishi is able to offer an optional battery that is expected to last up to 2.5 hours (with a full charge). LED lights also produce very little heat for the light they produce. This translates into instant-on (no warm-up necessary), and non-existent cool-down periods.

The trade-off for all this portability and longevity is a small (but impressive) viewing area, and low (but usable) light levels. The image size is 12" to 60" (optimal is 40" to 50"), and the LEDs generate approximately 250 lux (lumens per square meter), making it fully usable in a dimly lit room with low ambient lighting! Not bad for a native resolution of 800 X 600 (SVGA), and 1024 X 768 (XGA) maximum.
Note from Technophile: How about a portable big screen theater? Or watching movies with a portable DVD player? Or enlarged video for more exciting gaming? Or mobile video for camping (just charge the battery during the day using a PV (Photo Voltaic) panel. The applications are limited only by your imagination, and with a street price of just $799, you may not even be limited by your wallet. Buy it now at the CDW Mac Warehouse.
