Ben and Felix produce a laser guided infra-red grid array sensor, connected via i2c to a micro controller with mechanical relays to disconnect the power to a device that causes fire! They integrate a Hitatchi HDD44790 based LCD display to create a menu and interface for calibration with an enclosure designed with Autodesk Fusion 360. If advanced technology is almost distinguishable from magic then an electronics component that sets itself on fire has “let the magic blue smoke out” and killed the magic.
