In this directory are text and GIF files covering the design of my


knock indicator.





The files are as follows:





circuit.gif       a B+W schematic of the knock indicator circuit


                  I've been using for the past few years.


                  All parts are identified.





layout.gif        a color drawing of the PCB layout of the knock


                  indicator using a Radio Shack PCB.





parts.txt         list of parts for constructing a complete knock indicator, 


                  including mounting box and hardware.

                  This picture shows what is possible when the PCB 


                  is wrapped in a mechanical design.





theory.txt        a text file describing the Theory of operation of the


                  knock indicator design presented in this directory.


                  (incomplete at this time.)
