The only fully absolutely free-standing, unibody implementation of a harmonograph I knew of at the time. Yet another unparalleled element is that the unbiased pendulums impact each and every other via delicate transfer of energy by the body. This final results in somewhat a lot less pedictable but gorgeous Lissajous curves. The full factor is entirely knock-down for straightforward transportation with particular focus offered to extremely potent friction joints. (Has to assist 100 lbs. of swinging guide!!)
This had some massive crowds completely memerised at woodworking exhibits as they watched it do its astounding factor. I went through 4 prototypes above two years to get to this style and design. The intention was an tasteful design that generated… effectively… stylish layouts! Resources: Walnut, 2 automotive U-joints, enormous blocks of lead (perfectly encased – melted it down myself), paper and pen.
Google “harmonograph” and “lissajous” to get an strategy what this is about. Also, to see how other men and women have applied the same strategy and examine a far more entire historical past of how mine arrived about, see local.wasp.uwa.edu.au/~pbourke/surfaces_curves/harmonograph/ (bottom of world wide web webpage).
