This is a fun, light-hearted question and not meant to be taken too seriously.
As a little fun thing between a group of friends, we found this question on a desk at work sometime ago about a PCB that had been removed from a typical household object. The question basically was what household object do you think this could have come from and what could the function of the board be.
We've come up with all sorts of possibilities such as a smoke detector, microwave oven, old TV, etc, however none of us can confirm whether any of us are right as there isn't any answer to the question available. Given the large number of capacitors and resistors, we don't think it's a simple clock. Furthermore, we haven't been able to deduce what the large plastic piece in the middle is - we're hovering towards a transformer (some are thinking it's a speaker), but the shape of it is throwing us off.
Can anyone shed some light as to what they think this board could be from or what they think it is used for so we here can stop debating on this.
Battery is there for size reference.
