I have an idea to a home made dashcam, but I need some help.
I have a PI 3 that I want to use for it.
I can connect and use a IP cam or a USB cam.
The camera stream should loop in memory, i'm thinking 90 seconds (maybe using: PiCameraCircularIO)
A connected button should, when pressed, save the past 90 seconds and the future 300 seconds.
Can any one help me how I make this work, and start up with the PI.
Kind regards J;-)
