Sorry, no one's interested, so I think I should delete the post

Oh wew, much more complex circuit then what I had (at least it must work :P). Also attached schematic is outdated, OPAMP was changed to MCP6004, instrumentation amplifier was changed to INA826, and full-wave rectifier was changed to one that can work with a single supply. Need to get back to it once higher priority tasks come down.

For the skin contacts I tried using a couple of uSIM headers but not sure how well that would have worked since build circuit had a few issues (should have breadboarded it first). I have also got some proper ones (the ones that have gel on the sticky pad), so have that to fall back on. Is that what you meant by connectors?

Ah gotcha, the cables I got use a 3.5mm audio jack, any reason not to go with this?
