Veracity control wheels for gimbal operators using RC transmitters
12 years old. Gear and prices may have changed since.
What the thread found
- Control wheels connect to RC transmitter trainer ports and convert rotary input into digital data streams that replace joystick signals for gimbal operation.
- The Veracity wheels add no system latency because all processing occurs within a single data package heartbeat timeframe.
- Gimbal accuracy depends on the gimbal's own sensor capabilities, not on the control interface, since gimbals like the Movi use gyro feedback without direct position feedback on camera axes.
- An open-loop system like the Jimmy Jib cannot maintain precise wheel-to-camera relationships because there is no feedback about actual camera position or movement, only torque limiting.
- Achieving exact wheel-to-camera axis relationships requires closed-loop servo systems with encoder or resolver feedback mounted directly on individual axis drive trains, which are heavier and more expensive.
- The Veracity design prioritizes precision through hand-machined wheels instead of off-the-shelf components, adjustable counterweights for balance, and high-resolution encoders to create better operator feel.
- Sensitivity adjustment knobs on individual wheels scale output independently, and a zero button allows wheel offset to match the RC transmitter's zero reading.
Depends on
- Gimbals like the Movi cannot provide the same precision coupling between wheel and camera as high-end heads with direct encoder feedback because they lack position feedback on camera axes.
- System latency varies by RC transmitter model, ranging from as low as 10ms to much higher, which affects overall control responsiveness.
- The Veracity system was designed for operators who prefer traditional geared head feel over RC joystick operation and will perform differently depending on gimbal type and settings.
- Comparisons to other third-party systems like Hurricane wheels and Bartech focus interface systems were mentioned but not thoroughly evaluated in the discussion.
