GroupGets has been releasing FLIR Lepton Dev Kits that allow users to overlay the thermal imagery from a lepton sensor onto the colour image from a Raspberry Pi Camera and create custom software. One of the requirements of the overlay is that the Pi Camera and the Lepton are held at a fixed distance apart. We were asked to fix the problem by creating an attractive little casing that held both cameras and allowed for mounting to a tripod, the result is what has been nicknamed the “Ruby”.
