Aim to develop an open-source, modular 16 mm film projector using commonly available parts and proven mechanical elements.
Reuses existing claw, shutter and transport mechanisms from Eiki RT-2 and compatible optics from various brands.
Implements a high-density 800 W LED light source with water cooling, achieving up to twice the brightness of a 250 W halogen lamp.
Replaces mechanical shutter with digital shutter through LED flicker and offers variable frame rates from 0 to 30 fps.
Uses brushless motor with magnetic encoder for precise film transport and control electronics based on ESP-Wroom-32 and Arduino Nano.
Prototype presented in expanded cinema festivals showed brighter, sharper, and whiter projection, with initial flicker issues resolved by mechanical alignment and firmware tweaks.
Comparison tests confirmed superior brightness (up to 22 000 lux) and color fidelity versus halogen and xenon projectors.
