Here now we going to build solar panel based lamp to replace oil lamp mostly use in Diwali festival and in Hindus temples traditionally.
Let’s get started
Before putting everything together let see given circuit diagram
So here is two diagram showing different part of circuits
make a connection accordingly
3D modeling/printing
and Here final result!
Conclusion: Since as I thought and as you see in first cover picture, final result is different because tp4056 module don’t work on low current supply hence I used big 1w solar panel which doesn’t seem matching with design in build but it working as expected
