Ever wonder how a rotary telephone works, how sailors and pilots navigated by the stars, or how mechanical calculators perform complex math using only gears? Then you've come to the right place! Our Own Devices is a channel dedicated to the fascinating world of vintage technology, and the many elegant and ingenious ways our ancestors solved even the most complex technical problems. Want more fascinating history? I am a regular staff writer for Today I Found Out and many of its sister channels: https://www.youtube.com/@TodayIFoundOut I also have a historical adventure novel titled 'Our Own Devices' set in 1920s Morocco.

Video Description
In previous videos we have examined a variety of vintage heat and smoke-activated home fire alarms. However, fires also produce another, more insidious combustion product: carbon monoxide. Starting in the 1980s, a number of different sensor technologies have been developed to detect this invisible killer, including electrochemical, biomimetic, infrared, and semiconductor types.
