BS2, BS2 Carrier Board, SoundPAL, PIR, and a PowerTwig to the rescue.
I have a small garden pond with some pet Koi fish, Problem is, it's a Varmint magnet.
Every night we get visits from half a dozen different animals trying to get dinner. Mostly Ferral Cats.
I have Cat and Apossum protection built into the banks of the pond, so they aren't so bad,
It's the :swear: Raccoons that do the most damage, They are smarter then your average bear..
One in particular has found a way thru the defenses, and managed to pull some scales
off of one our prize Koi, Not Cool!
Anyway, I needed something that could detect a small heat source, then make an appropriate sound
To scare away the nasty creatures that would eat said pet fish... So I made this thing...
Using this stuff... (It's no mystery from what bag these parts came in..);)
BS2
BS2 Carrier Board
Photoresistor and associated RC components, (it only needs to run at night..)
PIR sensor
SoundPAL
and WBA's super slim, high powered, ultra sleek, and really cool PowerTwig 800mA voltage regulator.
I stuffed all the parts into a "TupperWare" weather resistant container, added a little sealant...
And now I have a rough and ready "Habitat Relocation System", Able to scatter even the most stubborn pests.
I have a few improvements in mind, like maybe a small vibrating motor slapping the container side,
and some flashing Red/Green Led "eyes" to help increase the sense of urgency, and panic...O_o
I had fun building the H_R_S, Thanks Parallax!
