            playing with this myself, on the conductive-ink/paint/glue<br>
            end; with some mixed results.<br>
            <br>
            *  I've lit LEDs with conductive ink on paper, which is
            kinda fun. A<br>
            thing to note is that the graphite/graphene based inks are
            resistive;<br>
            depending on the length/thickness of the trace, you might
            not need an<br>
            extra resistor for the LED! Also, you can draw
            potentiometers!<br>
            <br>
            * I've tried 3-d printing a circuit board for use with the
            conductive<br>
            glue. The idea I had was essentially a block with little
            troughs for<br>
            the glue to stay in; push the glue in there, push down the
            components,<br>
            and voilà. Except it didn't work.  I blame the roughness of
            the thing;<br>
            next try will have deeper (and a little wider) troughs, and
            I may use<br>
            a syringe to apply the glue instead of the eyedropper-type
            applicator.<br>
            <br>
            * I also want to see if you can incorporate enough
            graphite/graphene<br>
            into polymorph/shapelock plastic to make it
            conductive/resistive.<br>
            I've got a big thing of lamp black I picked up at an art
            store that<br>
            would at least make the plastic black, but I don't know if
            its<br>
            graphite is in the right form to do conductive.  Thanks for
            the links<br>
            to RMS Graphite, Sam; that should point me in the right
            general<br>
            directions.  I figure if this is doable at all, I could make
            3d<br>
            circuit structures, and then cover them in normal,
            insulative plastic,<br>
            and end up with blinky-light plastic objects. Or something.<br>
