Watch This Crazy Video: Hobbyist Builds 40-Watt Laser Shotgun

“DIY Laser Guy,” Drake Anthony, whose YouTube channel includes a plethora of homemade laser creations, recently unveiled his newest: a laser shotgun comprised of 5W-laser beams, totaling 40 watts of power.

The parallel beams are manipulated with lenses, similar to how a choke modifies the spread of a shotgun blast.

The massive diode array is powered by a huge lithium polymer battery pack (capable up dumping 250A) and the laser array is regulated by 24 LM317 drivers.

“This is definitely the craziest thing I have ever built, but I hope to beat this invention with something even crazier before too long,” Anthony wrote on his YouTube channel, StyroPyro.
