This Dude Built A 40W Laser Gun!
Drake Anthony from the Styropyro YouTube Channel just built this 40W laser shotgun! The laser is made up of 8 parallel 5W laser beams totaling 40W. The diode array is powered by a lithium polymer battery pack and the laser array is regulated by 24 LM317 drivers. You've got to see it for yourself!
You probably shouldn't try this at home unless you intend on making a youtube video.
