Appendix 1 Revised diagrams for *development System

  1. *Development system is the basic PCB that also holds the Simple bike computer but will also allow work on more advanced bversions of the Bike computer.
  2. In Appendix 2 we have a “Bike computer only” PCB and associated components

PCB of Bike computer and test accessories.

This is the modified PCB diagram that now corresponds with the Theoretical bike and test Electrical circuit Diagram.

Fig.40 updated PCB for development system

The Theoretical diag. +component layout

The theoretical electrical circuit of the Bike computer circuit , the test components and a layout diagram for component placement.

Fig.41 modified theoretical circuit for development work on simple bike computer.

Note. In the text we discovered that there were errors in the pcb shown, which as far as I can see are now eliminated.
