Christmas, and the lights and baubles go
up. Recently I was playing with a long
chain of beads, and generated a standing
wave. It was very cool.
I propose that an outdoor display could
use shiny or transparent beads (or even a
string of lights) with a small motor to
generate a standing
wave. By changing
the frequency, the waves could be made to
appear to move around and change size.
Several strands of beads with different
waves would be a real eyecatcher.
This might be best suited to a store
display given the expense - though
motorized displays seem common
enough.
Should have been called the Bungston Effect

Done with string.

Do this with beads, rotate upwards and you've got a pretty fountain or other display. [AusCan531, Dec 03 2016]
Hose wave

This sort of wave produced by shaking is what I had in mind. The frequency of the shake can change the number of waves or "humps" as she calls them. [bungston, Dec 04 2016]

You needed to get this out to the masses Bungston before
some usurper popularized it. [link]. |
|
| |
Very cool! Thank you for the link!
Now if one constructed a chain out of bowling balls... |
|
| |
I thought the size and configuration of the bead link set the standing wave? A motor could refeed the piled chain for a continuous loop. |
|
| |
[wjt]. The concept of a continuous looped chain powered
by a mechanism underground led me to this idea. By
assembling a series of these chains being fired upwards and
falling downwards in a standing wave, you could make a
chain fountain. [link] |
|
| |
My query was about how much change you can do with the motor on a single strand. |
|
| |
A single chain doesn't look that dynamic. |
|
| |
Varying the size of the bead might make it wobble around a bit. Turning the speed down on the motor might risk entanglement. |
|
| |
The linked wave / chain fountain is not what I had in mind when I posted this. It is a different effect possible with a bead chain. |
|
| |
I posted a link showing the sort of thing I was thinking about: humps or bulges produced in a chain or hose, which one can alter or make seem to move up and down by changing shake frequency. |

So a physical display of the Fourier transform?, nice. |
|
| |
How about Standing Wave Bead Chainmail? It's the obvious derivative....confuse the enemy and all that kind of stuff.... |
|
| |
Maybe if the drive motors are fast enough and a couple of other involved physical actions (8th's razor lights), You'll get a knight with butterfly wings. ( back to 2fries' noodles) |

I think this idea needs strobe lights too |
