We're playing music with lasers for the 4th of July

Topics: Laser welding

It’s almost the Fourth of July, and before we all head out to celebrate with fireworks and barbecues, I thought we’d do something a little different to kick off our first video blog.  What’s the perfect song for Independence Day?  The “Star Spangled Banner” would be a pretty good choice, right?  Well, how about the “Star Spangled Banner” played by a high power industrial laser! Check out the video below:

 

 

This is something I’ve been wanting to do for years, and it combines two interests of mine – music and lasers.  How was this accomplished?  Well, very briefly, the frequencies of the notes in the “Star Spangled Banner” fall within the frequency range of the laser.  I programmed the machine to fire the laser at the right frequencies to match the notes in the song, and matched the beam on time to the length of each note (imperfectly).

So, enjoy the music and “fireworks” from the sparks flying off the titanium and two alloys of aluminum.  Feel free to leave comments or questions in the comment section.  I think this was so cool we'll have to do it again.  Happy 4th of July!
