I work as an electronic engineer (but seem to do more mechanical engineering now) and I am always more impressed with the ingenuity shown in clever mechanical solutions to problems compared with electronic solutions.

Compare this to an electronic timer controlling a servo to open and close the shutter - a trained monkey could design that!
