DIY solar panel charger? (lemmy.ml)

Hi fellow Lemmings,

Hopefully some of you are knowledgeable about electronics. I know nothing really. But, I just found my old LG POP (GD510), which has a back panel which houses a small solar panel. I thought it could be a fun personal project to try to put that tiny panel to use.

Do you think it is worth tinkering with? I'm guessing it could only put out a negligable amout of energy, but maybe it's usable for something. If it is, could anyone point me to some resources to try and understand how it works before I solder anything?

Also, as a general question: have you ever done a project like this, where you repurposed an old electronic device of yours?

You need to check the maximum and minimum voltage the panel produces, depending on that is can be used to charge batteries with the corresponding voltage range.

But a small panel like that is probably not very useful.

I'll check it tomorrow! I didn't think it would be highly useful, just sounded like a fun project!
