Diy camera

I happened to touch a model plane and an aerial photo. What a coincidence! I like playing with cameras, too.

In fact, the principle is very simple, really simple. The position of the camera is sensed by sensors such as gyro accelerometer, and then the data is processed by single chip microcomputer and instructions are issued to make the motor (usually brushless motor) act to offset the unnecessary action of the camera.

The required materials are: control panel, brushless motor, electric regulator, tripod, sensor, control lever and battery.

At present, there are many types of pan-tilt control panels, which are generally available.

Russian: AlexMos (commercial control panel, used in many places, in many movies.

Germany: simpleBGC (open source products, mostly in the low-end market, few people want to use it in the control of SLR and professional cameras. But it is used a lot on mobile phones and gopro)

USA: storm32: (Also open source, 3-axis control effect is ok, many people use it on SLR)

In fact, diy stabilizer is not difficult, but debugging is time-consuming. Especially open source. Generally adjusted are

Center of gravity, pid value, need a little knowledge to adjust.

Another answer upstairs is to use Arduino+ three-axis gyroscope. Is it okay? Yes, but Arduino's processing performance is limited, and it involves microcontroller programming. Even if it is written, it is very cumbersome to make various modifications to debug in order to use it in various environments.

If it is practical, if you really want to diy, you can choose to use the control panel to diy, roughly adjust the parameters for dozens of minutes, and accurately adjust the parameters for months or even more than a year.

China also has world-famous products, which can be used after simple debugging, just like computer assembly, with little difficulty.
