Schematic fixes: - C1 is too small; need more than 100k to get 1:1 between schematic and PCB, no warnings Add splits and labels to get below 200bpm - C1 is too small for film; is film needed? - Fix R25/R1 connection - One potentiometer for internal clock rate. Switches: Momentary-normal-off pushbutton to manually reset. More repo cleanup, adopt github .gitignore.
