DIY 3 Axis Gimbal for Smartphone: A Step-by-Step Guide

In the age of smartphones, capturing smooth and cinematic footage has never been easier. However, achieving stable and professional-looking videos can be quite challenging, especially when on the move. A 3 axis gimbal stabilizer allows you to counteract unwanted camera movements and jitters, providing you with buttery smooth shots. Building your own DIY 3 axis gimbal for your smartphone not only saves you money but also enhances your understanding of filmmaking technology. In this guide, we'll explore the materials needed, the step-by-step process of construction, and some tips for effective use.

What is a 3 Axis Gimbal?

A 3 axis gimbal is a device that rotates on three axes: pitch, roll, and yaw. This design allows for stabilization across multiple movements, making it a preferred tool for videographers and filmmakers. Each axis compensates for different types of movement, ensuring that your footage remains steady even when walking or running.

Why Use a DIY Gimbal?

There are numerous reasons to consider constructing your own gimbal:

• Cost-Effective: Professional gimbals can be quite expensive. Building your own can significantly lower costs.
• Customization: You can tailor the design to suit your specific needs and preferences.
• Learning Experience: Creating a gimbal from scratch provides you with practical knowledge about mechanics and electronics.

Materials Required

Before diving into the assembly, gather the following materials:

• Brushless motors: These will be used for stabilization and should have a good torque-to-weight ratio.
• Microcontroller: An Arduino or similar microcontroller is essential for programming and controlling the gimbal.
• Battery Pack: Choose a lightweight lithium polymer battery that provides ample power.
• Mounting Plate: This will secure your smartphone onto the gimbal. It can be made from aluminum or plastic.
• 3D Printed Parts: If possible, 3D printing the frame can enhance the precision of your build.
• Wires and Connectors: For connecting motors to the microcontroller and battery.
• Tools: Basic tools including a soldering iron, screwdriver, and a wrench set.

Step-by-Step Assembly Guide

With your materials ready, let’s begin the assembly process:

Step 1: Designing the Frame

The frame is crucial for the stability and weight distribution of your gimbal. If you have access to a 3D printer, consider designing and printing a frame that fits your components snugly. If not, a sturdy wood or plastic frame can also serve the purpose. Ensure that the frame allows for the free rotation of the three axes.

Step 2: Adding the Motors

Mount the brushless motors onto the designated spots on your frame. Each motor should correspond to a specific axis:

• Yaw motor: Controls the left and right movement of the camera.
• Pitch motor: Adjusts the up and down tilt.
• Roll motor: Stabilizes the tilt to avoid horizon slant.

Ensure the motors are securely fastened and able to pivot freely.

Step 3: Wiring the Components

Solder the wires from each motor to the microcontroller. Follow the manufacturer's instructions for ensuring proper connections. Remember to check your wiring for any potential shorts before powering up the system.

Step 4: Integrating the Battery

Connect the battery pack to the microcontroller, making sure to adhere to its voltage requirements. Secure the battery to the frame in a way that maintains balance and does not hinder the movement of the gimbal.

Step 5: Programming the Microcontroller

Utilize open-source software like Arduino IDE to program your microcontroller. You will need to configure each motor, tuning parameters to ensure that the gimbal functions effectively across all axes. There are numerous tutorials and libraries online to assist with the programming process.

Testing the Gimbal

Once assembled, it’s time to test your gimbal. Mount your smartphone using the mounting plate and ensure that it’s balanced. Power up the gimbal and move it gently; you should observe the motors kicking in to stabilize the smartphone. Fine-tune the motors settings in your code if necessary.

Tips for Effective Use

After constructing your DIY 3 axis gimbal, keep these tips in mind to maximize its potential:

• Balance Weight: Make sure your smartphone is well-balanced on the gimbal before operating it.
• Use the Right App: Certain filming apps can help you achieve better stabilization and enhance your footage quality.
• Practice Smooth Movements: Enhance your filming technique by walking slowly and smoothly to minimize abrupt motions.

Creative Uses for Your Gimbal

Your newly constructed gimbal opens a world of possibilities for creative video projects. Consider using it for:

• Travel Vlogs: Capture stunning landscapes and city sceneries without the jitters.
• Event Documentation: Film weddings, parties, and other events with professional-like quality.
• Sports Action: Shoot exciting sports footage that keeps pace without losing stability.

Final Thoughts

Building a DIY 3 axis gimbal for your smartphone can be a rewarding project that enhances your filmmaking capabilities. With the right materials, a solid understanding of mechanics, and some programming skills, you'll have a powerful tool at your disposal. Whether you are a budding filmmaker or just wish to capture stunning videos for personal use, a gimbal can revolutionize the way you shoot video.
