In this post we have a high power solar LED garden light circuit which works with a solar panel, to charge a battery during daytime and switch the LED on at night and off in the morning automatically. Now let’s go through how this thing works step by step in a crude way. How This … Read more
In this post we will see how we can make a very simple solar-powered LED system which also has a battery charging feature. This circuit will help us light up high-power LED (SMD) lights and the power can be anywhere from 10 watts to 50 watts, so we can decide as per our need. Now … Read more
In this post we learn to make a super cheap but super effective solar charger, mimicking an MPPT effect, all under $3! Even a beginner can make this, no complicated stuff, just a solar panel, some diodes, and a switch. That is it! What is Maximum Power Point Solar Tracking (MPPT)? Now when we hear … Read more
Here we talk about the cheapest and simplest solar battery charger circuit. It has only two parts – a solar panel and a diode. That is it! But still, it works. No let us understand how. Understanding the Circuit Working So we take a 16V 1A solar panel which gives free power from the sun. … Read more
Here we talk about a simple solar charger circuit. It takes power from a 20V, 1A solar panel and then charges a 12V battery. We are using a 7812 voltage regulator IC, three 1N4007 diodes, and a 2.2kΩ resistor to make sure the charging happens safely. Now let’s go step by step. Circuit Diagram Solar … Read more
This post is about one kind of circuit, which is for controlling the level of water, and this can be useful for making an automatic system that will keep giving water in a dripping manner to plants in a garden that is at home without needing any person to be there. This idea was asked … Read more
