How to hook up a solar panel to a 9v battery powered recording module?
I'm planning to make an outdoor thing that plays a sound so I want it to run off of a solar panel. I'm going to use a 9 volt radio shack recording module. I was just wondering what kind of solar panel I need, and how to hook it up. Plus if you know of a recording module that runs on a solar panel that would be great. Thanks a lot! :)
