Still planning (for want of a better term) the neuromorphic Raspberry Pi 5 so that it can be powered by solar energy. Decided to add the battery gauge as well as external LEDs for indicating charge/done, etc by both solar and other energy sources.
As you can see this is an extremely early mock up of how it may look.
Needing to 3d print the battery cover then either use veroboard or maybe consider a custom pcb (though it would make sense to design and test on breadboard initially).
Still concerned it’s only going to be capable of 3A yet carrying on regardless for the time being! Nothing ventured, nothing gained…
