Professor Michael Robinson came into the lab with the idea to make an Astrolabe. This is a medival device used to tell time similar to how a sundial uses the sun to tell time. The majority of materials for this build were fabricated on the laser cutter. Professor Robinson used a custom Jupyter notebook to create a vector file containing appropriate calendar days and star charts that could be easily sent to the laser cutter's CAM software. One tricky part in making this was ensuring the acrylic stock was aligned so the laser cutter could imprint designs on both the front and back of the astrolabe pieces. The pointer is 3D printed and all the pieces are held together with M3 screws. This is truly a very unique and interesting device; great work Professor Robinson!
