Our friends at SparkFun have launched a new educational video series called Engineering Roundtable, with the latest episode featuring one of our founding members, Joel Bartlett.
In the second episode of the series, Joel shows and tells us about the process of visualizing sound called Cymatics. Watch grains of salt organize into several different shapes in response to different frequencies passing through an acrylic plate. Learn the history, how it works, and how you can build your own.
Episode 1 featured Chris Taylor (who also helped SSD get started back in 2010) makes a sign out of EL wire that looks like neon:
Also check out the article “5 Questions for SparkFun’s Engineering Roundtable” from Wired magazine introducing the video series and interviewing Joel, Chris and their third engineer, Nick Poole.
Watch for new episodes the 2nd and 4th Monday of each month.
Way to go, Joel and Chris!
