I constructed it using a Wire EDM and a NC milling maching. I, at the time, was using Acad to generate prints from which I fabricated the parts. Total time a little over two months aprox. The aluminum balls are stopped by rare earth magnets that come to within 80mm of the balls in which an electric current is induced when the balls are moving causing them to become an electro magnet of sorts which damps their movement as long as they are moving. When the balls stop so does the attraction.
The machine sets in the entrance foyer of the Bateman Physical Science Center, Physics & Astronomy department F wing.
Tim Cook and Wyane Easterling came to me with a small cardboard box with two holes in it with a shaft through it, and two balls hung by strings with a cardboard cut out of a cam on the shaft. They asked me to make a machine so I created this with input form them on what they would like to see. I then came with the design and prints to make the machine which I proceeded to do.
lawrenceball sounds like he is mentally challenged and is craving attention, I wouldn't listen to his blathering, perhaps send him a good psychiatric reference. This is a beautiful machine.
I am the designer and builder of the machine you see in the video. It was my swan song at Arizona State University. I worked in the Physics machine shop for 20 years building things that are one of a kind like the machine here. Have you built one lately?
Your opening sentence "This is a Primitive etc." I suggest you learn to use a little more tact in your comments. It took me 3 months of designing machining and anodizing to produce this one of a kind IN THE WORLD machine.
This is a primitive example of John Whitney's Differential Dynamics which he uses in his computer films. With the help of Mike Tusch and Dave Snowdon I have developed a harmonic maths on the shoulders of Whitney's principle which we call harmonic maths, which I used to generate music for Pete Townshend's Lifehouse-Method music project. With 30,000 points calculated in realtime the points go much further than double and triple!!! see lawrenceball org

Beautifully executed, Mr. Jarrette!
TheMacallan223, I hope you'll update your description, giving credit where due...

-- has a full description and annotated pictures of this beautiful apparatus.
Wow. Thank you.

lawrenceball and his 30,000 points all sound like garbage. we call that harmonic insults.
perfect design, gary. where is this installed?
