siemens 3000



hacking a siemens 2000 film projector.

i replaced the old motor with a modern brushless dc motor, and the old lamp with a 250w 24v halogen reflector. 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.
