Just a heads up on the content of the March 2014 Everyday Practical Electronics magazine. There is a full build article by Allan Linton-Smith & Ross Tester for an Infrasound Detector.Pages 10 to 19 inclusive.There is a recent presentation on Meteor Infrasound etc from IMC Poland here Infrasound PDF by Elizabeth Silber.
Hi, It was an interesting talk. I'll need to have a look at the magazine! I trawled through the data from my electronic barograph to see it I could detect a signature from Chelyabinsk but unfortunately nothing. Thanks for the info. cheers, Bill.
