The new $229.99 picoprojector just announced by TI and Brookstone represents a real tour de force in System Realization. It combines a TI DLP (digital light processing) Pico light engine, video circuits, audio circuits, a 2100 mAh battery, and a speaker into what is essentially a carry case for the iPhone. Here’s a photo.
The unit uses a 15-Lumen LED as a light source and is said to be able to project a 640×360-pixel display for images as large as 50 inches in diagonal. Here’s a photo of the device in action:
When not acting as a projector, the device can double as a backup battery for the iPhone.
