Description
This is a case for a solar battery charger. It can charge from USB or the Sun, and it delivers USB power when switched on. It is based on a set of parts from Adafruit:
Breadboard-friendly SPDT Slide Switch
It is also held together with M3 nuts and bolts, and I had to solder a different connector on the solar panel (not to mention solder together the parts inside).
I usually tuck the charger into a pocket and pin the solar panel to the outside of my bag, so that it accumulates charge while I'm out in the Sun. The button was meant to be sewn onto the bag so that the panel could be looped over the button but for the moment I'm using safety pins.
The battery is slightly big for the device, so I print it in PETG and then the springiness of the plastic keeps the battery from moving around. Other internal components are held by pegs.
