TV repair shop: We had a game we called "One Twenty to the Board." (USA, and are mains power is typically 120V) We would take junk PCB's and attach a stripped AC power cable to two random spots and plug it in. Sometimes nothing, sometimes MASSIVE showers of sparks. More than a few times we would blow the 20amp breaker which was actually next door! We found that the large 40-ish pin chips were the best... they'd look like Roman Candles going off. Tons of fun. |

Year circa 1960 At Radio Row lower Manhattan NYC TAB surplus, 111 Liberty St. Old warehouse, with war surplus store and power supply mfg My first Summer job: I was just the kid, a go-fer. I learned a LOT that Summer.... When closing up, with breakers OFF a tech placed 1 W 10 Ohm carbon comp resistors inserted carefully into the mains outlets.....various places like behind sales counters and mamagement offices..... Next morning the boss (who usually opened up) got a BIG SURPRISE as breakers were turned ON. BANG! SMOKE! FLAME! at each rigged outlet..... Jon |

I have a 300V power supply, sometimes I would put 1k ~ 22k ohm 1/4W resistors across it and watch the fireworks. |

When I was an apprentice mechanic, one of the guys quietly wired the cars ignition coil to the drivers seat and asked me to drive it it… sure enough, I turn the key and feel like I’ve been shot in the butt :-DD I still drove the bloody thing into the shop with it zapping me the whole time though :-DD You probably couldn’t get away with that these days but was all in good fun :) Good times :) |

Early Weller TCP soldering stations had a transformer base on the front with 24V AC terminal posts to connect the iron. A small bead tantalum discreetly wired across the terminals never disappointed :) |
