Eliminate shop dust automatically with Arduino

What’s the best way to dispose of the dust that is produced when cutting with power tools? YouTuber Bob Claggett’s answer is to automate the process entirely, using a series of PVC sewer pipes to transport air to a central vacuum system, along with an Arduino Uno for control.

Airflow is regulated via a blast gate for each power tool, which is opened and shut using a hobby-style servo and custom linkage system. The powerful dust collector is controlled with the help of a relay.

Cleverly, a voltage sensor is employed for each power tool needing dust collection, allowing the Arduino to turn on the system and decide which gate to open without any human interaction.
