Hi there. I would like to connect my pi to my car battery. I intend to use a 12v to 5v adapter to connect the pi to the battery (via the fuse box) with a constant current.
I am then thinking of using another circuit from the ignition to control the power up/power down sequence.
Is it possible to trigger OnOff Shim using a separate circuit such as the car’s ignition instead of a switch?
