Airsoft Turrent

Created by @sameer-kulhari

Total Time Spent : 12hr

June 26th — 7 Hours

4:00 PM – 6:00 PM : Turret Circuit Design & Component Selection

I began by designing the basic working mechanism of the turret system, including how the pan and tilt movements will be working. After researching various options, I selected suitable components such as:

  • Servos for pan/tilt movement
  • BLDC motor for Shooting pellets
  • ESP32-CAM for camera and control
  • Power supply

Using Cirkit Designer, I created the circuit design for the turret, Once completed, I added it to the GitHub repository.

6:00 PM – 11:00 PM : 3D CAD Design of Turret

Using Onshape, I designed the full 3D model of the turret. The model consists of 5 custom parts and 4 assemblies in total.

Designed Components:

  • Base Mount
  • Rotating Base for Pan
  • Tilt Frame
  • Camera Plate
  • BLDC Motor Holder

After modeling, I exported the STEP files and uploaded them to the GitHub repository, along with rendered images.

5:00 PM – 8:00 PM : ESP32-CAM Firmware Development

I developed custom firmware for the ESP32-CAM using the Arduino IDE, aiming to provide full control of the turret via a Web User Interface. The firmware integrates prebuilt libraries for servo control, motor management, and live camera streaming.

Features Implemented:

  • Web UI accessible over local Wi-Fi
  • Servo Control for pan/tilt using PWM
  • BLDC Motor Control
  • Live Camera Feed from ESP32-CAM

The source code (.ino) and related files were uploaded to the repository.

8:00 PM – 10:00 PM : Final Documentation, BOM, and Repository Setup

I finalized the project by preparing essential documentation and organizing all files in the repository:

  • Created a Bill of Materials (BOM) after comparing multiple component vendors
  • Wrote a detailed README including features, usage, and image references
  • Compiled a Project Journal summarizing the design, development, and testing process
  • Uploaded all critical files:
    • Circuit design and schematic
    • 3D models (STEP, PNGs)
    • Firmware and libraries
    • BOM and project notes

The repository is now complete and ready for demonstration, submission, or further development.
