Open the original Pertinent Information Gathering PDF

This three-page research attachment, titled Mechanical Clock – Pertinent Information Gathering, is preserved from the existing Wiki page.

The document records 50 research entries with a component or topic, an identified mechanism or working principle, a YouTube link and a type classification. Entries 1–30 use direct video links; entries 31–50 use YouTube search-query links for further study. They are not 50 separately verified videos.

Its topics cover gears, escapements, pendulums, mainsprings, weights, bearings, winding and fabrication, together with Arduino, DS3231 timekeeping, LCD/OLED displays, stepper motors and the ULN2003 driver, buttons, geared DC motors and servos.

The PDF provides research references. Inclusion in the table does not establish that a component was selected, built or tested for the final clock.
