YouTuber Builds Automatic Backpack Umbrella That Deploys
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.
Key Points
- 1Uses an ESP32 and resistive rain sensor to detect drops and trigger automatic deployment
- 2Employs a worm gearbox and high-torque motor to compress umbrella springs reliably without back-driving
- 3Demonstrates practical embedded-mechanics integration for hands-free rain protection and prototyping mobile accessories
Scoring Rationale
Novel DIY hardware innovation drives score, but single-source hobbyist project limits scope and broader impact.
