It would be hard to find the solar cells for that price let alone the whole light assembly etc.
Step 1: Let's get started
I was searching for a container that was in the experimenters budget along with one that had some qualities I was looking for.
this box has a 4 side snap feature. It is easy open/ easy close etc. The one thing I liked is the rubber seal built in the lid portion.
This should make things fairly water tight.
I may use this during emergency situations (preparedness). As a Ham Radio operator I need to be prepared to work emergency communications at some point. A solar charger for a cell phone or other device would be handy.
