Re: [ATM] analog computers

It doesn't matter voltage or current in and out.  It's ultimately to drive
a motor slower and slower or faster and faster.  Accuracy, five percent,
one percent, really, what ever I can get if it's elegant.  A sin wave
divided by it's phase shifted self would do. A very slow sine wave, uhm
24*60*sixty.. one over.., eleven and a half micro hertz, and frequency
stability is important.  The technology I knew would have required hundreds
of components, hours of tinkering, and room at the dump.  I was hoping for
something either insanely simple or modern analog technology.  A digital
solution, yea sure, a snap, resistors and a ROM.  But digital is well, it's
just so, well, vulgar.

Would that an exponential could be well matched to some portion of the
tangent.  Then a motor shorted across a supercap might have worked.
