Last year at Bateaux en Fête the Sequana was fitted with a GoPro Hero 3+ Camera to film other models. Even with the shakiest footage edited out there's still a lot of roll and pitch.
Thanks to the suge in Drones/UAVs sales brushless gimbals can know be had for less than $100.
I hence ordered a Tarot T-2D V2 brushless guimbal.
The T2D is a 2-axis brushless gimbal. It features two brushless motors (one for pitch, one for tilt) and uses MEMS gyros/accelerometers.
Refresh rate is 2Khz. 2000 times every second the controller will correct the camera position based on inputs from the gyros.
When you hold the gimbal (with the camera installed) you can "feel" it's working correcting the jittering from your hand and faint humming sound from the motors.
Being only a 2-axis gimbal it won't correct yam jitters but this is much less critical than pitch and roll on a boat (and even on a Drone/UAV).
The gimbal works great on itself but it can also be connected to the RX and lets you control pitch and roll from your TX. There are then two modes of operation:
The T2D can be upgraded and set-up on your computer (USB cable/adapter comes with it).
Haven't hooked it to the computer yet but I might set it up so that there's still some (minimal) roll and pitch so that the footage would still look "boat-like".
Most BL gimbals are designed to be installed hanging under a drone/UAV. The T2D is no exception. Hence The Thing.
The mount is some sort of container crane with a piece of 110mm * 45mm plywood the gimbal will be bolted on.
It also features a lower platform to hold the 3S LiPo battery, 5V BEC and 2.4G RX for remote operation.
It will obviously replace the original wheelhouse during filming duties.
Parts will be cut from 5mm plywood on one of the routers from the MCCR's workshop.
