Nearly four years after producing the first prototype, Professor Shree Nayar's BigShot DIY digital camera is now available to the general public. The main parts of the camera include a gearbox, a lens wheel, a printed circuit board with a 3-megapixel sensor and a 1.4-inch LCD panel, a LED flash, a rechargeable battery, a dynamo and a hand crank providing an option to use the camera when the battery is fully depleted. The final product is an improvement over the prototype, which made do with a 2-megapixel imager and no LCD screen at all. The lens wheel has three optical modules that allow you to take three types of photos - a "regular" lens with a horizontal angle of view of 40°, a wide-angle lens and a stereo lens for 3D photography. The BigShot camera is primarily intended to be an educational aid targeted at schoolchildren, with the kit being available for $89+shipping.
