I realize this has been talked about before but I picked up a personal alarm at a garage sale for 10 cents and figured I would use it in a rocket. As to how to put it in....that's where I'm lost. I've heard of people mounting in to the shock cord as below:
But I'm thinking that isn't an acceptable method of attatching it (ie electrical tape and a sock). I am reluctant to mount it in the ebay as that might prevent the sound aubile at longer distances. Thoughts?
