The PiKon project is a low-cost telescope kit using 3D printed components, an off-the-shelf heating duct, some Meccano, and a Raspberry Pi camera with the lens removed.
Earlier this year at Maker Faire UK, we talked to Mark Wrigley about the PiKon telescope, and how he went about building the 3D printed, Raspberry Pi powered, telescope.
Based on the Newtonian design, with a 113mm (approx. 4.5″) primary mirror, the telescope dispenses with the traditional flat secondary mirror, placing the small (25mm×25mm) Raspberry Pi camera board at prime focus.
The PiKon telescope is now crowdfunding on Indiegogo, and is roughly three quarters of the way towards its funding target with just a few days still to run on the campaign.
