Standing Wave Bead Chain Ornament

Attract those shoppers!
  [vote for,

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 https://www.youtube...watch?v=YZ1-4DVLSZ0

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

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
