  Motivated by the topologically insulating (TI) circuit of capacitors and
inductors proposed and tested in arXiv:1309.0878, we present a related circuit
with less elements per site. The normal mode frequency matrix of our circuit is
unitarily equivalent to the hopping matrix of a quantum spin Hall insulator
(QSHI) and we identify perturbations that do not backscatter the circuit's edge
modes. The idea behind these models is generalized, providing a platform to
simulate tunable and locally accessible lattices with arbitrary complex
spin-dependent hopping of any range. A simulation of a non-Abelian
Aharonov-Bohm effect using such linear circuit designs is discussed.
