This project is a mini solar phone charger. You can charge up your phone with a solar panel generating of about 1.5v to 2v.
Just go through the steps and i am sure you would find it very easy to make.
Remix version of:
But here i have used much compact solar panel.
Step 1: Gather Materials!
1. Mini Solar Panel
2. Duct Tape
3. 1N5817 Schottky Diode
4. 470uF Capacitor
5. 5v Step Up Converter
Step 2: Something About Solar Panel
This mini Solar panel generates of about 1.5v to 2v which is of course not enough for phone but go through cicuit diagram to make this suitable to charge your phone.
Step 3: Affixing Panel
Affix the panel to your phone with the help of Duct Tape.
Step 4: Create the Circuit!
Follow the circuit diagram.
Here firstly, voltage regulator circuit is there which is made with the help of a schottky Diode and Capacitor. The it is connected with 5v Step up converter which will convert voltage from 0.7-5v to 5v. This makes your phone charges.
Now, your hardware is ready to make your phone charge.
Step 5: The Final Step
Just connect the data cable from DC-DC Boost Converter to your phone and it will make your phone charge in seconds.
