Making a mini drone with a camera requires a combination of electronics, programming, and mechanical assembly. Below is a step-by-step guide to help you build one:
—
Components Needed
1. Frame: A lightweight frame (carbon fiber/plastic)
2. Motors: 4 coreless brushed or brushless motors
3. Propellers: 4 propellers matching motor size
4. Flight Controller: F3, F4, or Betaflight-compatible controller
5. Electronic Speed Controllers (ESCs): Needed for brushless motors
6. Battery: LiPo battery (3.7V–7.4V)
7. Camera: Small FPV (First Person View) camera (e.g., AIO FPV camera)
8. Transmitter & Receiver: 2.4GHz RC controller & receiver module
9. FPV Video Transmitter (VTX): To send video feed (if using FPV)
10. Microcontroller (Optional): Arduino or Raspberry Pi for autonomous flight
11. Sensors (Optional): Gyroscope, accelerometer, GPS (if needed)

Steps to Build a Mini Drone Camera
1. Assembling the Frame
Use a lightweight material (3D print, carbon fiber, or plastic).
Mount the motor brackets at the corners.
2. Installing the Motors & Propellers
Attach brushed or brushless motors to the frame.
Connect motors to the ESCs (if using brushless motors).
Secure propellers (clockwise and counterclockwise pairs).
3. Connecting the Flight Controller
Mount the flight controller in the center.
Connect the ESCs/motors to the controller.
Flash firmware (Betaflight, Cleanflight, etc.).
4. Adding the Camera
Use an AIO FPV camera (built-in transmitter) or a separate small WiFi camera.
Secure the camera at the front of the drone.
Connect it to the power source and transmitter.
5. Setting Up the Transmitter & Receiver
Bind the radio receiver to the transmitter (remote controller).
Ensure all controls (throttle, yaw, pitch, roll) work properly.
6. Powering the Drone
Use a lightweight LiPo battery (1S or 2S for mini drones).
Secure it properly and ensure balanced weight distribution.
7. Testing & Calibrating
Connect to Betaflight or Cleanflight software for calibration.
Test in a safe indoor environment.
Adjust PID settings if needed.

Optional: Adding Smart Features
Use Arduino/Raspberry Pi for autonomous flying.
Add GPS for waypoint navigation.
Use an optical flow sensor for stable hovering.

Final Thoughts
If you’re new to drones, you can also buy a DIY drone kit (like Makerfire, Eachine, or BetaFPV kits) and modify it by adding a camera. Would you like specific recommendations for DIY kits?
