Makezine_COTM_Resistors-BadgeInstructables user science4u used this simple arrangement to create an ad hoc paper resistor — a strip of heavy paper with pencil lead limiting the flow of current, with precisely spaced paperclips serving as leads. Desperate for a 10K? Draw your own! [Thanks, Laura!]

    ..often seen the pencil-lead resistor maneuver, but i’ve never seen anyone attempt a pencil-lead (both sides of the paper as dielectric) capacitor. i wonder if one could get even a couple of picofarads if one wore through nearly a pencil’s worth of graphite.
