Power box
After getting my HAM radio license, all I could find on the internet was people taking their HAM radios mobile and running them off solar power. Most of the ones that I had found online for purchase were super expensive, so I decided to build my own.
Also, it was a pretty simple concept and I got my son interested in it a bit. Even got him to do a little work on it!
I started simple with a tool box, a small solar panel, a solar charge controller and a battery.
