Human-powered laser cowboy rifle

thingiverse

This Wild West laser rifle gets its juice from a good ol' fashioned lever cocking action - no batteries needed, partner!\r\n\r\nIt works by turning physical motion into electricity through a clever little stepper motor built right into the lever itself.\r\n\r\nThe stepper motor is a 12v powerhouse with a built-in 5:1 gearbox, meaning just a small movement will generate enough power for one laser blast after another.\r\n\r\nI constructed a laser target to go along with it, and below you'll find a video that takes you through the whole process in painstaking detail.
