YouTuber Builds Automatic Backpack Umbrella That Deploys
|
2.7
YouTuber Current Concept recently built an automatic backpack umbrella that deploys when a resistive rain sensor detects raindrops. The system uses an ESP32 microcontroller, three servos, a servo-driven cam, a high-torque motor with a worm gearbox, and quarter-inch Dyneema rope to extend and retract the canopy, plus a sliding carriage and limit switch for safety. It retracts when the sensor dries, leaving hands free.
