Some of the more possibly useful resistive material is found in certain
types of anti-static packaging, The key is that it is usually *flat*
black in appearance. Seems like Analog Devices is one place that likes
to use plastic bags and cardboard boxes that fall in this category.<br>

<pre wrap="">Hey Batz,
Charles Osthelder posted plans for a ribbon controller he designed using
resistive material from a grounding cuff. The plans can be found at
<a class="moz-txt-link-abbreviated" href="http://www.wiseguysynth.com">www.wiseguysynth.com</a>.
The cuff itself is item # 17250 from <a class="moz-txt-link-abbreviated" href="http://www.desco.com">www.desco.com</a>.
I purchased one for around $10. Maybe this could be a partial solution.

<pre wrap="">I've also tried the trick that's spoze to work with video tape. Buggered
if
I can get that to work. A piece of 1/2 inch video tape is spoze to be
slightly conductive and increases fairly lineally with length. I couldn't
get anything useful out of that. Not with the range of samples I tried
anyway. Likewise with conductive mylar. The type of stuff used in IC
anti-static packaging. My guess is that whatever is conductive in these
materials is like a layer witin a laminate. So that from the surface it's
an insulator but has a sheilding property. Or in the case of video tape,
is
covered by a binding layer perhaps.
