Well, then so is any electronic component. I'm old enough to have played with analog computers. They were fun to solve differential equations with. Not necessarily electronic, either. I've also done it with pneumatic stuff, bellows, nozzles and flapper valves, and with water levels in vertical pipes. Those were real fun too. You could *see* what was going on without instrumentation. It's been quite a while since I last did that, though. These days, everything is electronic. Jeroen Belleman
