In my ongoing research to manufacture my own CCRs I again experimented with epoxy glue mixed with graphite. This time I wanted to achieve lower resistance values and I mixed in a lot of graphite. I placed the 'blob' between two thumbtacks I used as electrodes.

The resistance value is around 13 KOhm now. I placed this new component into my circuit and recorded the signal. A lot of crackling noise was in and some fairly good pk modulation.
