#182341 - No coupling Responding to: ???'s previous message |
Beautiful video. But this one does not have any real coupling (basically a tiny bit of air movement created by the neighbours) between the individual pendulums. It's just a question of them having different (and carefully controlled) time constants creating something similar to the lissajous curves most of us have played with on an oscilloscope:

| An excellent demonstration of coupling between oscillators | 01/01/70 00:00 | |
| Many many years ago... | 01/01/70 00:00 | |
| 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 | |
| Length of gnd/vcc "bumps" in relation to period difference | 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 | |
| huh? | 01/01/70 00:00 | |
| Just different location of screw adjustmenton clock pendulum | 01/01/70 00:00 |
