“A Square shaped Solar Light which completely made from scratch.
The goal for making this was simple, I wanted to make an emergency light powerful enough for daily use. (To light up a certain area of my home during blackouts)
LEDs are all powered by a 2600mAh 3.7V Li-ion cell, I’ve also added a TP4056 Li-ion charging IC in this setup, and the LEDs are all driven by an AO4406 N channel Mosfet IC.
Also, this light contains a Dusk to Dawn feature which means when we plug the power IN for charging, the Main LED Light turns OFF and when we plug the charger out, it turns back ON.
this feature is essential for using this light outside with a solar panel connected, we dont have to turn ON/OFF this light daily, the solar panel will trigger this light during the day and night time automatically.
This Instructables is about the whole built process of this light setup, so let’s get started!
