“In this Instructable, I am going to show you how to make a Rainbow Solar Mason jar. 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.
The Solar Mason Jar depends wholly on the sun for power, which ultimately means it saves you more energy, and you dont have to worry about unplugging once it is fully charged because the battery automatically stops charging once its full, and 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.
The Mason Jar Light is equipped with inbuilt sensors. Once the sun begins to fade into the horizon, it automatically switched on leaving your garden with colorful rainbow light.
The project is based on a cheap LED driver chip QX5252F in the TO-94 package. I have already posted an Instructables on Solar Lamp by using the same IC. But this time, I will show you how to modify the circuit so that you can run an RGB LED to produce rainbow colors effect.

1. Solar Panel -2V
2. Controller QX5252F
3. 47 uH Inductor
4. RGB LED
5. Sliding Switch
