A company, Alternative-Photonics, supported by researchers at the University of Sheffield’s Institute of Physics, has built a telescope, primarily out of 3D-printed parts, and used the Raspberry Pi camera module to take pictures through the lens. There’s been a bit of over-enthusiastic news coverage of it, most notably on the BBC. Mark Wrigley, one of the developers, has reported on the Raspberry Pi forums that the idea eventually is to put the plans for the 3D printed parts out onto the internet so others can replicate the project. There’s a little more information on PiKon’s blog and more on the Alternative Photonics site and you can follow them on Twitter.
