How to make a Rf controlled small siren? Answered
I need to make a small battery powered loud(120dB+) electronic siren that is turned "on/off" by a key FOB type RF remote. I am currently trying to train my dog to not dig holes, etc, and need a small siren that can fit on her harness collar. I need to be able to push a button on the remote to make the siren wail, until I release the button. remote needs to be RF not IR. Any ideas?
