hacking a siemens 2000 film projector.
i’ve replaced the old motor with a modern brushless dc motor, and the old lamp with a 250w 24v halogen reflector bulb. this allows me to controll the speed and brightness of projection via a programmable microcontroller.
the sound head can be used as an input: instructions can be written in the soundtrack in shape of horizontal lines, and the microcontroller can be programmed to interpret these instructions and act upon them - closing the feedback loop.
film becomes both the carrier and the provider of information, giving the projector instructions how to project itself. even the ability to self destruct.
work in progress.
