Activity recorder modification
Some hardware modifications and new software can turn the
original circuit into a digital train travel recording unit. To use
the controller this way adds two switches, a potentiometer
(abbreviated “pot”), a relay, an external memory IC, and a few
other simple parts.
Here is the board from part 1 without the recorder modifica-
tion. The highlighted areas were not used in the first project
but the additional parts outlined here make the recorder.
