I just finished doing my DIY solar lantern project. I’ve always wanted to make one but I didn’t have the time to make one.
After the Earth Day, I decided to make time for this mini project of mine.
I’ve made a detailed documentation of this project including theory of operation, how it works, how to compute for the resistor value, and all these technical stuff.
Here’s a link to the detailed guide on how I did it.
