Musical Tesla concert is electrifying

Hackaday reader [Tyler Laseter] wrote in to tell us about an event that he and his fellow Tesla Orchestra team members are hosting next month.

The “Open Spark Project” is a concert event taking place on May 14th, which melds together electricity and music in spectacular fashion. The event features two large Tesla coils which are tuned to play musical notes while shooting bolts of electricity through the air.

Musical Tesla coils are nothing new around here, but we have yet to see someone allow the general public to play music on their coils. That’s what makes this event unique – anyone is encouraged to submit their to the Tesla Orchestra team, which will then be played back via a live video stream next month. Their web site offers up all of the technical details as well as the file format requirements for submitting music for the event, so get started on your entry today!

If a passive approach is more your style, stick around for a quick video demonstrating their coils’ abilities. Sure it’s Lady Gaga, but we won’t tell anyone you watched it. Plus, it’s totally legit when the song is being played using 20,000 volts.

Arduino solenoid concert

[jay] reminded us of this old video of solenoids banging rhythms on furniture and household objects. There’s no schematic, but in the video it looks like an Arduino drives a bunch of solenoids through relays. The PC interface is run on Pure Data, an open source programming environment for audio, video, and graphic processing. Thanks [Jay].
