Cell phone Gimbal
The gimbal was first described by the Greek inventor Philo of Byzantium(280–220 BC). Philo described an eight-sided ink pot with an opening on each side, which can be turned so that while any face is on top, a pen can be dipped and inked — yet the ink never runs out through the holes of the other sides.
We can define gimbal, A gimbal is a pivoted support that allows the rotation of an object about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support.
If we speak about the overview of technology, they applied this invention to ships and submarines, a minimum of three gimbals are needed to allow an inertial navigation system to remain fixed in inertial space, compensating for changes in the ship's yaw, pitch, and roll.
We can classify this cell phone gimbal in three aplications: rocket engines, photography and imagining and film&video.
- Rocket engines: The rocket engines are generally mounted on a pair of gimbals to allow a single engine to vector thrust about both the pitch and yaw axes; or sometimes just one axis is provided per engine. To control roll, twin engines with differential pitch control signals are used to provide torque about the vehicle's roll axis.
- Photography and imaging: Gimbals are also used to mount everything from small camera lenses to large photographic telescopes. In portable photography equipment, single-axis gimbal heads are used in order to allow a balanced movement for camera and lenses.[20] This proves useful in wildlife photography as well as in any other case where very long and heavy telephoto lenses are adopted: a gimbal head rotates a lens around its center of gravity, thus allowing for easy and smooth manipulation while tracking moving subjects.
- Film and video: Handheld 3-axis gimbals are used in stabilization systems designed to give the camera operator the independence of handheld shooting without camera vibration or shake. Powered by three brushless motors, the gimbals have the ability to keep the camera level on all axes as the camera operator moves the camera. An inertial measurement unit (IMU) responds to movement and utilizes its three separate motors to stabilize the camera.
- If we speak about gimbal, the most cheapest one is the FLY X3 PLUS DE IKAN, here is the web page that show this: http://www.hungamahub.com/video/Y5d1uqPIYPA/el-gimbal-ms-econmico-el-fly-x3-plus-de-ikan.html. .
- In our oponion we think that this camera´s instrument is very helpful and useful for improving the quality of the photo.
