snowflake world a.k.a. SFW
TL;DR: I got written up at the aforementioned tool and die shop for leaving a homemade 3s3p LiIon pack in the men's locker room, after someone somehow mistook it for a bomb.
I had (hopefully) made it somewhat rain-resistant by wrapping in clear packing tape, which also held the NdFeB onto the bottom/back (normally for holding it to my bike, for the lights that make it street legal at 6 AM during most of the year). The clear packing tape was because I hoped to be able to see when there was water getting in and if the strips joining the cells were rusting (they were, lightly).
I don't have a locker-- it was supposed to go into my backpack as usual. My mistake was sticking it onto an I-beam while I got my shirt out of said backpack and changed into it, and then forgetting it. Their mistake was being a paranoid mindless Murkin-- who believes their favurite government official that tells them "land of the free, home of the brave" means the worst is about to happen and we all have to act accordingly-- and assuming that same worst thing, without spending another 30 seconds working on an awareness of their "situation."
It wouldn't have been so difficult. All 9 cells were positioned with the label printing facing out: ICR18650A220 (can you believe it? 18650 form, 2200mAh) and the letters YLE (the manufacturer in China) and 3.7V and a plus and a minus at either end... and a bar code which matched a 12-digit serial number, which would be pretty important for quality control, or something. Very readable. Very obvious. It would have been nothing for someone to notice and look it up on their phone, but instead they got on the phone with the cops and started evacuating until a guy recognized it and had a good laugh (and many more in the following weeks). But I'm the one who incited a panic. Not that whistleblower.
A few rhetorical questions: what kind of self-respecting terrorist is masturbating in the village of <deleted> instead of getting busy in a real city with lots of potential victims? What kind of self-respecting terrorist takes a bomb to a factory and then puts it in the vicinity of toilets and clothes racks instead of near some industrial chemicals, preferably flammable ones? What kind of self-respecting terrorist puts a bomb on/near a wall, at chest level, almost directly in front of a mirror where lots of people will have a good reason to look directly at it, instead of hiding it anywhere?
More recently there is a suggestion/subliminal message posted around, whereby this tool and die shop ironically encourages "attention to detail." The company has more than a few ongoing quality problems-- they're on what is basically probation with their more important customers including Honda. My unhappy conclusion due to this and a dozen other obscenities: the people who make decisions there also kind of suck at thinking, fail at creative problem solving, and generally aren't as properly addicted to believing true things as one would hope.
