i finally got my brother's scanner working here at home, so i scanned a
couple pages from a journal article about the driven Chua's circuit. this
is the basic circuit that i plan to build my module around.
just the schematic:

complete facing pages including the schematic, the transfer function of
the nonlinear negative resistor, and the equations that govern the system:

i plan to make this circuit run from the same power supply as my ASM-1,
which is +/-15V. does anyone see any immediate problems resulting from
that? i think the PIV on the 1N4148's is 75V or so, so that shouldn't
cause any trouble, should it? some component values are going to have to
change, for the performance of the circuit, i just want to make sure that
nothing will smoke or go crazy otherwise.
i also want to use an op27 instead of a 741 for the op-amp, because of its
low-noise operation. on the AD page for the op27
(http://products.analog.com/products/info.asp?product=OP27), they claim "A
guaranteed swing of +/-10V." does this mean that outputs approaching
+/-15V will be distorted, or will be clipped off? please pardon my
ignorance, as i'm kind of jumping into this.
