Seven-Controller EtherCAT Orchestra

July 20 2012, 13:01

When I first saw the Intel Industrial Control in Concert demonstration at Design West 2012 in San Jose, CA, I immediately thought of Kurt Vonnegut ‘s 1952 novel Player Piano. The connection, of course, is that the player piano in the novel and Intel’s Atom-based robotic orchestra both play preprogrammed music without human involvement. But the similarities end there. Vonnegut used the self-playing autopiano as a metaphor for a mechanized society in which wealthy industrialists replaced human workers with automated machines. In contrast, Intel’s innovative system demonstrated engineering excellence and created a buzz in the in the already positive atmosphere at the conference.

In “EtherCAT Orchestra” (Circuit Cellar 264, July 2012), Richard Wotiz carefully details the awe-inspiring music machine that’s built around seven embedded systems, each of which is based on Intel’s Atom D525 dual-core microprocessor. He provides information about the system you can’t find on YouTube or hobby tech blogs. Here is the article in its entirety.
