I can now slap my table to turn on my PC, thanks to a simple vibration sensor
With an ESP32 and a simple sensor, I can slap my table to turn on my PC for less than $5.

The act of turning on your PC is a simple one, but pressing the power button isn't the only way to do it. In fact, I would argue the power button is archaic, and there are significantly more convenient ways to switch on your PC when you're ready to use it. That's why I slap my table to turn it on instead.
