PVC Air Horn to Scare Your Friends (or Cats)
Intro: PVC Air Horn to Scare Your Friends (or Cats)
Build a home made air horn out of PVC pipe. This air horn is very loud (but not deafening) so you can use it to scare the trick-or-treaters when they come to your door! Combine this with last week's floor switch project to make it automatically go off when someone steps on the switch!

Can you control the frequency? ( like a boat horn wich is close to 120Hz )
Thanks in advance
