I couldn’t build a bird house when I was healthy, much less now. LOL
If your condition allows, you might be interested in some of the articles of Jeffrey Yago (PE) on small, do-it-yourself energy projects. His latest is a “Solar suitcase” for tiny power uses (cell phone, laptop, radio, etc.).
I really liked his trailer project a few years ago.

One pretty good source of components that includes some how-to and other info (included here because of the easy-to-understand tech. info around the site). Readers should also seek other, more basic PV solar information that’s available on many sites around the Net.

If it’s of no interest to you, that’s understandable. People in various places live under different conditions and have different needs. Some people in some places will benefit from the knowledge. I like tech. stuff.
