Household technology tends to disappear into the background, which is exactly why its history is easy to overlook. Clocks, lightbulbs, and thermostats have all quietly changed how a home is lit, heated, and scheduled, and each has been reimagined more than once.
The pairs here, Analog Clocks vs Smartwatches, Incandescent Bulbs vs LEDs, and Analog Thermostats vs Smart Thermostats, compare a simple physical mechanism with a version that senses, calculates, or connects. In each case the interesting questions are practical ones: how much energy is used, what can be repaired at the kitchen table, and how much of the device's behavior the household actually controls.
The guiding question: How did everyday household devices change when simple mechanisms gave way to electronics, sensors, and connectivity?
