#182347 - Just different location of screw adjustmenton clock pendulum Responding to: ???'s previous message |

Adjusting the lengths of pendulums must be a nightmare
that is, by means of a thumbscrew, how you adjust a penulum clock (not the battery driven ones with a fake pendulum) Erik The only difference is that the pendulum on clocks are rigid so you then have the screw adjustment at the bottom, moving the weight up and down. |

| You don't suppose that was for a reason, do you? | 01/01/70 00:00 | |
| Sensitivity since lack of "mass" to uphold frequency | 01/01/70 00:00 | |
| Even in well-filtered applications ... | 01/01/70 00:00 | |
| Ground bounce... | 01/01/70 00:00 | |

| That was an interesting problem | 01/01/70 00:00 | |
| Signetics (later as Philips) made 74HC7046 | 01/01/70 00:00 | |
| That's a really nice demo | 01/01/70 00:00 | |
| One of many | 01/01/70 00:00 | |
| On a similar note | 01/01/70 00:00 | |
| No coupling | 01/01/70 00:00 | |
| Very nice... | 01/01/70 00:00 | |
| Easy if they have a screw adjustment + web cam | 01/01/70 00:00 | |
It remembers me... | 01/01/70 00:00 | |
