steam train

Electronics can be used to simulate the most amazing range of different things. Cybernetic models, sound effect generators, electronic noses - you name it, it`s been tried! Some things, obviously, are more difficult than others; the sound of a steam engine is certainly easier to imitate than the taste of certain types of coffee. However, it can be a problem to fit a realistic sound effects generator inside a model engine. It`s possible, though, using miniature components and a little p.c. board.
