Maker Faire Bay Area 2014
This custom ruby laser was built from surplus parts, and produces enough energy in a single shot to drill holes in metal. Ruby lasers have also been used to make hologram snapshots and to measure the distance to the moon.
About the Maker
I work on Virtual Reality and other hardware at Valve. For my previous day job, I built computer peripherals such as keyboards, mice, and joysticks that were meant to be used inside MRI machines.
