What the thread found

• The device replaces a standard power plate and supplies 12V or 24V output to power cinema cameras like RED or Alexa
• It supports both single battery and hot-swap battery configurations depending on setup requirements
• Any digital motor can be integrated, and performance characteristics match commercial offerings in speed, smoothness, and noise levels
• The unit mounts to camera top cheese plates via 15mm bridge adapters or other configurations, allowing quick switching between mounting options using rosettes
• Standard digital motor pinout across Preston, Heden, Scorpio, and similar systems uses 7-pin Lemo connectors with consistent assignments for motor power, encoder signals, and identification
• Digital motor encoder pins tolerate inverted wiring without damage in most cases, causing only functional issues rather than hardware failure
• ENG cinema lenses from manufacturers like Canon, Fujinon, and Angenieux use different motor control protocols than digital cinema motors, typically employing serial control and 20-pin Hirose connectors

Depends on

• Limited technical documentation was initially available; creator directed interested parties to contact directly for specific pinout details
• The two AB Gold mounts used in the design create a visually larger appearance than the actual footprint
• The prototype images and specifications were not fully accessible through the provided link during the discussion
• Encoder A and B signal inversion behavior varies by manufacturer and may be outdated industry practice
