First-person, immersive — how to fix a speaker that won’t turn on

Two jobs for an appliance repairman: a Dyson vacuum switch the customer bought himself but couldn’t fit (‘is the repair guy all talk?’ — strip, swap, test run, success); a Bluetooth speaker that won’t turn on — prying the battery is the easiest way to start a fire, swap in a new cell, spot weld, tape it, it has power, fill with glue, charging wattage comes up, perfect repair

Job one: the customer brings a Dyson vacuum and a switch part he bought himself at home but couldn’t fit — ‘I reckon the repair guy is all talk’ — let’s see today whether he is; take it out, fit a new one, test run, installed, perfect repair. Job two: a speaker that won’t turn on, open it and see what’s wrong: prying like this is the easiest way to set the battery on fire (a warning); grab a new cell, spot weld it; a bit of tape; it has power, OK, see if it plays; fill it up with glue for the customer, a bit more glue; watch the charging current — the wattage comes up, OK; charging; the little heart-shaped color-light speaker with a screen, perfect repair. Comments: the most refined man on Douyin (creator liked it); if you were nearby I’d bring my pressure cooker; should the Dyson be opened and blown out; post your address (creator: you can find it here too); can you come fix a water heater (yes, happy to take that off your hands); can you fix charging shoes.
