There are plenty of fun laser toys on the market these days. This Homemade 40W Laser Shotgun is certainly not a toy. It emits 8 parallel 5W laser beams, allowing you to kill balloons, wooden objects, and everything in between. The diode array is powered by a 250A Lithium Polymer battery pack.
This laser shotgun is powerful and dangerous, so it shouldn’t be used as a tool. It does look kind of fun to use though. What do you think? Are you impressed?
