Adafruit PCA9685 16-Channel Servo Driver
I have received a Rasberry Pi 5 8G and Camera from Core Electronics,
My truck is park inside a Bottlebrush Paperbark tree and the flowers will soon be appearing. A family (soon to be ~fingers crossed~) of Chitty Chitty (Wagtails) are eyeing it off.
there are lots of designs for Pi Based Camera Wildlife traps. They need to have image detection / recognition to be practical.

Decided not to. It is too complicated to get the audio to it. Perhaps .wav files to get proper Hi Fi Audiophile cred? Not worth it.
FAULT : Both channels intermittently becoming quite and distorted.
When i tried to power the Wi Fi source from a USB source there was a huge hum so i just temporarily powered it off a battery pack. This time i should derive the Power from the 12 Volt DC heater line and that way there are no external earths.
The audio input needs to be wired to the in/out panel.
Fixed that and biffed out that horrible bluetooth
abomination i had and relpaced it with an automotive one.. Deriving the
12 volt from the heater voltages.
FAULT : The 330 Ohm 5 watt resistors are cooked.
I left out a link .. I did put a link on LK4 / 5 which complete the feedback loop presumably can remove them for testing. The links I left out are next to them.
