Experiences with WHM-BG artificial horizon modules for camera stabilization equipment

What the thread found

  • The device weighs less than one pound total and draws between 0.1A and 0.2A at 5 to 18V DC through a 2.1mm center-positive connector.
  • Power can be supplied via P-tap, 9V battery pack, or 0B Lemo connector using various cable options from different manufacturers.
  • The module can be mounted using either velcro, a 1/4-20 thread, or integrated into monitor mounts on stabilization rigs.
  • The LED display measures 1.81 by 2.94 inches with 0.59 inch height, while the sensor box measures 2.5 by 2.5 inches with 1.16 inch height.
  • Orientation of the sensor box must be maintained for proper operation.
  • The module requires initial zeroing against a physical bubble level before use, which takes approximately three seconds.
  • Gyroscope-based compensation allows real-time correction of roll errors during acceleration and deceleration, addressing limitations of older accelerometer-only systems.
  • The LED display is adequately bright but benefits from a sunshade in direct daylight.
  • Mounting directly to monitor posts or using dedicated monitor mounts provides solid connection compared to velcro alone.
  • Third-party power cables using genuine connectors from alternative suppliers cost significantly less than manufacturer cables.

Depends on

  • User reports indicate the Hirose connector design takes up unnecessary space and would be more practical as a 90-degree variant.
  • The specific mounting configuration depends on the type of stabilization rig being used.
  • Older competing systems with only accelerometer sensors show reduced performance during sled acceleration and deceleration compared to this gyro-based module.
  • Polarity verification is recommended when using third-party power cables despite built-in protection.
  • The LED brightness may require supplementary shading in bright sunlight for optimal readability.
