Solar powered on/off line timelapse photography

Introduction

Create offline timelapse photographer power by solar power using Raspberry Pi. When the Raspi connects to the internet, it will start transferring the images to a net storage. The uploaded photos will be then shown on a separate web page. Also, by triggering GPIO pins, Raspberry Pi will send a separate photo directly to the net storage. These photos are used to adjust the position and alignment of the camera.

Connect to internet

My Raspberry Pi 4 uses WPA to store wifi and ethernet data at /etc/wpa_supplicant/XXXX.conf file. It includes

country=ee
update_config=1
network={
        ssid="My Phone"
        psk="very secret passphrase"
}
