[Frameworks] how to power a projector mounted on a rotating device

[Karl Reinsalu]

I recall a 35mm installation that used an ac cable with a pre-built slip
ring design. They built the turntable and film looper themselves, but
sourced the cable from a film industry rental house. Might be worth an
inquiry with a production house like William F Whites or similar. Otherwise
possibly an industrial electrical parts supplier? Best of luck!
