Hi Rehmi, Thanks for the insight. Any hints as to which non-metal-element materials we should be looking for in the composition labels? This particular spool caught my eye because of the explicit silver content in the composition; a known conductor.

[deletia] This is what I'll be trying first... My primary concern is how to go about buffering/protecting the inputs; touch + static = fried CMOS! Should be fun. :-) Andrew. -- Andrew Plumb, VE3SLG mailto://andrew(at)plumb(dot)org http://www.plumb.org/tekmage/ spk2_0.0.2: http://www.plumb.org/tekmage/source/spk2/ -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org
