I'm very interested in the train windows (especially in white) doors (white) and bases. If this really gets off the ground, count me in. Kevin (27 years ago, 25-Aug-99, to lugnet.trains)

(...) The debouncing isn't the real problem, it's the variable resistance as the switch is being pressed which alaises the touch sensor. By building a MUX circuit which does thresholding and debouncing you effectively make the system way more (...) (27 years ago, 25-Aug-99, to lugnet.robotics)

You could always make a multiplexing circuit which does the thresholding and debouncing for you. Once the status of each switch has been turned into a binary state you could then use resistors to create a sort of D/A which works reliably -- just as (...)
