building a remotely controlled flashlight:
For another attraction held during a Halloween party already mentioned in episode #025, I also built a flashlight which can be remotely controlled. This is ideal to put the participants in complete darkness and have glowing clowns chase them. For this I added a tiny micro-controller and IR receiver in off-the-selves flashlights, and used a camera shutter remote control. We will see how to deal with the size constraints using parametric search.
For more details about the Halloween party and infra-red theory, watch episode #025.
