Using a “hard to acquire” laser diode (I suspect the black market was heavily involved), Youtuber styropyro went and built what is allegedly the world’s brightest laser pointer. Based on that photo alone, I’m apt to believe him. The green laser is so bright “you need welder’s goggles to be in the same room with it” or risk eye damage. Damn, now that IS bright. Me? I am not that bright. If I were a laser pointer cats wouldn’t even chase me.
