If the video quality can be improved, the price of the gimbal is not a problem. The gimbal not only prevents hand shake when shooting video, but also facilitates camera movement. Of course, it costs quite a bit to buy. I don’t know if it’s the role of balancing, but it’s even more so if you add the motor to the angle.
However, there are gimbals made by hand using parts such as broken hard disks and earphones, which draw attention. In addition to reducing the weight by using a pipe, it moves stably through the gyroscope and two axes within the magnetic disk even if the needle or handle used for magnetic disk is shaken left and right or tilted back and forth. The production cost is said to be only $10.
The gimbal itself is cheap, but it has all the functions it should have. Related information can be found here.
