Step 1 - Drawing

Draw the diagram of the charger

Step 2 - Asknet Box

Open the ASKotec kit and get the tools and materials to use

Step 3 - Tools and materials

Identify the tools and materials

Step 4 - Tools and materials arrangement

Arranged the materials and the tools

Step 5 - Solar voltage

Find the total voltage of the solar panel

Step 6 - LED

Test the LED light voltage

Step 7 - Calculations

Calculate the Resistance

Step 8 - Bread board

Get the bread board and place it at the helping hand

Step 9 - Input wires

Fix a positive (+wire red in color) and negative (-wire black in color) for input source (power)

Step 10 - Diode

Fix the diode

Step 11 - Positive wire to the diode

Fix a positive wire from the input source (+wire) to the diode

Step 12 - Resistor

Fix the resistors in positive side of the diode and have to be in series for easy calculation

Step 13 - LED light

Fix the LED light to positive side of the resistors

Step 14 - Regulator

Fix the regulator where the black side need to face your side

Step 15 - Small Capacitor

Fix the small capacitor

Step 16 - Big capacitor

Fix the big capacitor

Step 17 - Regulator and diode

Connect the left pin of the regulator to the diode and resistors

Step 18 - capacitor, diode, resistor and regulator

Connect the positive pin of the first capacitor to the join the diode, resistors and the left pin of the regulator

Step 19 - Regulator and big capacitor

Connect the right pin of the regulator to the positive pin of the big capacitor

Step 20 - Regulator and LED

Connect the middle pin of the regulator to the negative pin of the LED light

Step 21 - Small capacitor to the LED

Connect the negative pin of the small capacitor to negative pin of the LED light

Step 22 - Big capacitor and LED

Connect the negative pin of the big capacitor to negative pin of the LED light

Step 23 - All negative sides

In all connect the negative sides together

Step 24 - Positive wire

Fix +wire to the positive pin of the big capacitor

Step 25 - Negative

Fix –wire to the negative pin of the big capacitor

Step 26 - Female USB

Connect the female USB to the +wire and –wire on the capacitor

Step 27 - Test

Test the solar charger in the sun and test the output and charge the phone
