- petschge 5y agoEverything is as temperature sensor. Some elements also measure other signals.
- user_7832 5y agoJust made be realize, when you cook, the food is basically a temperature sensor. (Burnt) Toast is a great example.
- parenthesis 5y agoYou can use headphones as a microphone, or a (dynamic) microphone as a loudspeaker.
- ______-_-______ 5y agoThis is my favorite one. Being on stage and hearing music come out of your mic is a hell of a trip.

- amelius 5y agoI just hope my TV can't be used as a camera ...
- drdeca 5y agoWell, pairing the TV with a light sensor in a fixed location, and like, having the tv alternate between a sequence of different patterns, and recording how this changes the reading of the light sensor, and assuming that the room is otherwise dark, uh, apparently can be used to produce an image of the room as if taken from the location of the tv and illuminated from the position of the light sensor?
- amelius 5y agoOk. Most TVs are equipped with an IR sensor, so with a slightly more capable one you could take an image from the pov of the TV, and illuminated from the TV. Yikes.
