Holy Jeez, had it turned down as low as I could without just muting it and it still mad a hole in my brain. Super!

That's a great project. I loved the first one, but this one should be like the nuclear bomb! Very cool.

That will get the neighbors waving for sure. What a fun project. =)

Could you provide a link for the sound generator please?

Argh RIP headphone users!

Good luck with the bark device

You never show us the results off all your cannons. Please make a QUICK video on them. Thanks.

I have dogs constantly barking that are about 300 yards away. The sound travels to my home echoing off the mountain in from my of me.... What will reach that far to stop the dogs from barking constantly?????

Record an hour of it so I can use it
