Hey Everyone,
I know so little about electronics its embarrassing but that is where you come in. I am designing a back country search beacon for lost subjects. In short, I'll have a pole that will have a flashing light and loud as I can find low voltage speaker on it. The idea is to work as an attractant to people that are lost. They don't often wander too far and if the wind can carry the sound, it could guide them back to a trail. That said I need a waterproof speaker in the 100db plus range that can intermittently beep, chirp or honk. The battery (and whole apparatus) will need to be light but last probably 48 hours in cold conditions. We can use a small solar panel to charge it during the day. Thank you in advance for your help.
Any suggestions?
