[sdiy] Build a Lorenz Attractor

[s.thomas]

Hi all..been meaning to try and programme my little analogue computer (ex
university lab...was used to teach basic Analogue Computation to students I
think) to solve Lorenz's equations. So far I have managed to solve the
simple harmonic oscillator problem on it ..which is a lot of fun . Its got 4
opamp modules that can be configured as summers/integrators ..but
unfortunately no multipliers. I guess I'll have build a couple of those to
supplement it!  If I am lucky I might be able to drill the front panel and
add inputs/outputs for multiplier modules inside the existing case.

cheers
