Mains Transients Cause Spurious Switch-on of Toaster, Burns Gas Station Down
Transients in the mains supply of a gas station in the USA (called a petrol station in the UK) caused the spurious switch-on a microporcessor-controlled toaster one night after staff had all gone home. Since the microprocessor wasn't in its normal programme, it didn't switch the toaster off. The manufacturer of the toaster had omitted to include a thermal fuse, so the gas … [Read more...]
