 No, this is not actually a bomb, even though it does look more realistic than the ones in the movies. This is actually a motion controlled light that I built specifically for my dog. It uses a PIR motion detection system and it works by measuring infrared light that is radiating for my dog. While it can't tell me who or what moved, it can be set up to be more or less sensitive. I don't want it to trigger off of mosquito. So I set it up to only work on something as big as my 85lb German chip. And when it gets dark out, it will automatically switch out of solar charging mode so that when the dog walks by, bang, light.
