This is what people do on YT to attract followers. Stupid on top of stupid. Many years ago, a young husband and wife had the brilliant idea to make a video, showing that a pair of thick books would stop a handgun bullet. You know where this is headed, correct? The husband held the pair of books close to his chest, the wife fired the gun…. And promptly killed him. The wife was arrested on charges of manslaughter and if I recall correctly, she was sentenced. She left a pair of little children parentless. |

He just strikes me as a teenage nerd with the stereotypical teenage boy sense of invincibility. The story of Monalisa Perez and Pedro Ruiz is quite sad really: the boyfriend (they weren’t married) was clearly a moron who had no idea how powerful a Desert Eagle was. (I didn’t, either, before this story came out. But then again I wasn’t trying to get someone to shoot one at me! For those who don’t know: it’s really fucking powerful.) The girlfriend really didn’t want to do it. But he kept nagging her about it for over a month until she gave in. And even in the moments before pulling the trigger, she begged repeatedly to not do it. But he insisted. So she really didn’t want to do it, and she’s the one who has to live with the consequences. (She was sentenced to just 180 days in jail, followed by 10 years parole and a lifetime ban on holding firearms, so it seems to me that the courts understood the situation.) Because yeah, it turns out a single encyclopedia volume can’t stop a 50 caliber high-powered cartridge fired at point-blank range, no matter how many times you tell your GF that it’ll be fine… :palm: Oh, and their toddler was there and witnessed it. |

A failed Darwin award, but it was close >:D Maybe you learn something about transformer ratings before your next attempts. Or maybe not 8) |

--- Quote ---Something similar I've seen first-hand are aluminium-clad wirewound resistors, which have an element encapsulated in some kind of resin in an ali. extrusion. It's tempting to think that puttting these on a big heatsink will allow near-inifinte overload as the heat will get dumped into the ali. But what can happen is they blow one end of the resistor terminal out the end with substantial force - possibly trailing the unwound resistance wire behind it like a taser, --- End quote --- I had that happen with one of those one time. I was working on a 48v 3ph inverter project. I was suspecting some shoot through problem and to protect the unit while troubleshooting I had put one of those type resistors in series with the power supply to limit the current. A bit later, I had forgot it was there and was sitting hunched over with my back to the power supply (and that resistor) and that thing let go with a sound like a gun shot. It was a :o :wtf: moment for sure. And yes, the blown out end trailed a uncoiled string of wire. |

Many moons ago as a work experience kid in a film developing shop (remember those!) I took home a few boxes laden with discarded disposable camera shells. I extracted about a couple dozen capacitors and connected them in parallel to a single flash unit from one disposable shell. After several minutes of charging I triggered the flash. Made the loudest BOOM I've heard in my entire life, and temporarily lost some hearing in one ear. Vaporised the Xenon flash tube bulb of course, only the legs of the bulb remained with their PCB connecting wires. Never knew so much energy could be released from a single AA battery! |
