... without an Arduino (if possible).
I am aware there are well-made solutions like the WittyPi, RTC-Arduino circuits, and some others with relay switches.
If a power bank is directly connected to the Pi (which has shutdown with
sudo halt), all I need to do is break and reconnect the circuit and the Pi would boot up right? Is there a way to do this? Either at precise times with an RTC alarm or crude intervals with charging/discharging capacitors.
I'm guessing hacking the powerbank itself is more complex so maybe the USB wire instead? I am not quite familiar with electronics so any guidance will be of tremendous help.
(My aim is for the Pi to take a picture, shut down, boot 1-10 mins later, and take another picture, etc...)
EDIT A rough idea I had: Where AB can connect Powerbank and Pi or Reset pin and ground. I would probably control the on/off of AB with R and C values? But the circuit seems strange though as the capacitor doesn't have a route to discharge.
