Introduction: Cheap Handheld 3-axis Camera Gimbal

About: Aerospace Engineer working in Software Development with a passion for Hardware.

This is a cheap ( under $30) handheld camera gimbal that can pivot in three axes with three degrees of freedom- pitch, yaw, and roll.

Most camera gimbals are extremely expensive but if you just need a small gimbal for your action camera this is the perfect solution for you!

Step 1: BoM

  • 3 Servo Motors
  • 3 Potentiometers
  • Jumper Wires
  • Arduino

Tools

  • Hot Glue Gun

Step 2: Circuitry

Follow the table below for the most straightforward guide on how to wire it.

Step 3: Code

#include <Servo.h>
Servo servo1;
Servo servo2;
Servo servo3;
int pot1;
int pot2;
int pot3
void setup() {
  servo1.attach(5)
  servo2.attach(6);
  servo3.attach(9);
}
void loop() {
  pot1 = analogRead(A0);
  pot2 = analogRead(A1);
  pot3 = analogRead(A2);
  pot1 = map(pot1, 0, 1024, 0, 180);
  pot2 = map(pot2, 0, 1024, 0, 180);
  pot3 = map(pot3, 0, 1024, 0, 180);
  servo1.write (pot1);
  servo2.write (pot2);
  servo3.write (pot3);
  delay(50);
}

Step 4: Glue Servo

Glue the servo horn onto the body of the other servo so that they are facing two different axes to make a two axis servo gimbal.

Then, glue the last servo onto the two axis servo gimbal to another perpendicular axes (aka cross product of the two axes). Glue this servo onto the mount of an action camera box.

Step 5: Enjoy!

Enjoy you're 3 axis camera gimbal without breaking the bank!

Now you can take awesome shots with this nice gimbal!

    your concept is great but if you had given a video taken from it. it would be much better.

    I'm concerned that the servo "chatter" might be bad with this. Would you mind posting a video from the camera's perspective?

    I suppurt you. If he will upload a video I think it will be terrible. This is crap, not a gimbal.
