Wouldn't it be neat if TLC decided that those nifty 80-in-1 electronic kits
were something that could be done with LEGO bricks? Imaging having diode,
transistor, resistor, capacitor, inductor, inverter, NAND, NOR, etc. etc.
etc. bricks? True - any complex circuit would be huge, but directional
lighting would be trivial with a diode brick. With a transistor brick, you
should be able to make a constant voltage directional lighting system
(relying on a battery box for the voltage), though no lights will be on if
the train is stopped (of course with the right bricks, you could superimpose
an AC voltage on the tracks, though the unmodified train motor might
complain).

| In my opinion, that would ruin the feeling of LEGO. If you wanted things like that, then you could build them yourself (like a lot of people makes MindStorms sensors). LEGO is a toy for children, and I doubt that a 6-year old would have fun with (...) (25 years ago, 19-Dec-99, to lugnet.trains)
