This is a 3D printed Solar Lamp work based on the voltage booster IC QX5252F. The solar panel on the jar lid receives sunlight from the sun and converts it into electrical energy. The controller board charges the battery during the daytime and drives the LED during the nighttime.

It depends wholly on the sun for power, which ultimately means it saves you more energy. You don’t have to worry about unplugging once it is fully charged because the battery automatically stops charging once it’s full. As long as the solar panel is facing the sun, you can rest assured that it will charge and ultimately give your garden a colorful illumination.

This is a great project for people with minimal electronics skills, you can make this within an hour. This is an inexpensive and easy way to add charm to any outdoor space which gives off beautiful rainbow light well after the sunsets.

Components of Solar Mason Jar :

The solar panel receives sunlight from the sun and converts it into electrical energy. The controller board charges the battery during the daytime and drives the LED during the nighttime.

The solar lamp can be considered as a standalone Solar Photo Voltaic (SPV) system and contains four basic components:
1. Solar Panel: Convert Solar Energy to Electrical Energy

2. Controller: Charge the Battery ( Charger ) and drive the Load ( Driver )

3. Battery: Store the Electrical Energy

4. Load (LED): Provide the desired light output

    I have drawn the schematic on easyEDa online PCB design software. Then I designed a circular PCB for this project. Intentionally, I have used all the components through-hole type so that anyone including small children can also assemble it easily.

    Before finalizing the circuit, It is always a good idea to prototype the circuit on a breadboard. This lets you check to make sure that all of your components are working perfectly.

    Make the circuit on your bread bard as per the schematic. The LED should not glow if the circuit is correct. To simulate the dark condition, cover the solar panel with your palm. Now the LED should glow.

    To check the performance of the circuit, remove the LED and hook up the oscilloscope probes.

    You will observe that the output is not a steady DC voltage rather it fluctuates rapidly. In my case, the frequency is around 184.5 kHz. The peak to peak voltage is nearly 7.28 V and the average value is around 1.0 to 1.20V.

    Note: If you try to measure the voltage by a normal multimeter, it will show near to your battery voltage.Because your meters only measure the average value of a fluctuating voltage.

    Assembly Instructions

    For Soldering, you will need a decent Soldering Iron, Solder, and a Nipper. It is good practice to solder the components according to their height. Solder the lesser height components first.

    You can follow the following steps to solder all the components :

    1. Push the component legs through their holes, and turn the PCB on its back.

    2. Hold the tip of the soldering iron to the junction of the pad and the leg of the component.

    3. Feed solder into the joint so that it flows all around the lead and covers the pad.

    Once it has flowed all around, move the tip away.

    You can watch the YouTube video for assembling the PCB.
