The Raspberry Pi Foundation announced a month ago that it has built a tiny camera that can be hooked up to the little ARM-based computer. It’s expected to be sold sometime in April for $25, but today the foundation said it will give 10 pre-production models away for free to whoever comes up with the most creative uses for the camera.

“We want you to try to get the camera doing something imaginative,” Community Manager Liz Upton wrote. “Think about playing around with facial recognition; or hooking two of them up together and modging the images together to create some 3d output; or getting the camera to recognize when something enters the frame that shouldn’t be there and doing something to the image as a result. We are not looking for entries from people who just want to take pictures, however pretty they are.”

The contest is open until March 12, and ideas can be sent to iwantacamera@raspberrypi.org.

The Raspberry Pi foundation first started talking about building a camera module in May of last year. At the time, it was 14 megapixels, but the foundation noted that it might drop this number down to keep it affordable. It appears that the final version will use the OV5647, a 5-megapixel CMOS image sensor from OmniVision. The entire camera module will be 8×8×4mm, and it will attach to pins on the Pi board with a ribbon cable.
