ESP32 projects and notes in one placeGesture-Controlled 6-DOF Arm with MediaPipe and ESP32
How my 6-DOF arm follows a hand: a webcam, MediaPipe's 21 landmarks, a WebSocket link and an ESP32 driving six servos through a PCA9685, plus the jitter and power problems to plan for.
River-Level Monitoring with ESP32 and GSM: A Monsoon Design Sketch
How I'd build a low-cost river-level node for Assam's monsoon: an ultrasonic sensor on a bridge, an ESP32, a GSM link and SMS alerts on rate of rise. A local supplement to official flood warnings, not a replacement.
ESP32 OTA Updates from GitHub Releases, Without an OTA Server
How I ship ESP32 firmware updates from GitHub Releases with GitReleaseOTA: a version.json, SHA-256 checks, a non-blocking check task, a one-command release script, and the security gaps I still want to close.
10 Final-Year IoT Project Ideas for Engineering Students in Assam
Ten ESP32 project ideas for a final-year engineering project in Assam, each with a real problem behind it, the core parts, and the one detail that lifts it above a copied tutorial.
IoT for Assam Tea Gardens: Soil, Weather and Pest Alerts on a Budget
What a small sensor network can realistically do for an Assam tea garden: soil moisture and pH checks, weather logging over GSM, and alerts that tell you when to scout for pests, not magic pest detection.
