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
  • Arranged the materials and the tools



Step 4 - Test the folllowing materials

  • The total voltage of the solar panel
  • The LED light using the LED tester

Step 5 - Calculations

 Calculate the Resistance

Step 6 - Bread board

Get the bread board and place it at the helping hand

Step 7 - Fix the following materials

  • Fix a positive (+wire red in color) and negative (-wire black in color) for input source (power)
  • Fix the diode
  • Fix a positive wire from the input source (+wire) to the diode
  • Fix the resistors in positive side of the diode and have to be in series for easy calculation

Step 8 - Resistor

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

Step 9 - LED light

Fix the LED light to positive side of the resistors

Step 10 - Regulator

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

Step 11 - Small Capacitor

Fix the small capacitor

Step 12 - Big capacitor

Fix the big capacitor

Step 13 - Regulator and diode

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

Step 14 - 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 15 - Regulator and big capacitor

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

Step 16 - Regulator and LED

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

Step 17 - Small capacitor to the LED

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

Step 18 - Big capacitor and LED

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

Step 19 - All negative sides

  In all connect the negative sides together

Step 20 - Positive wire

Fix +wire to the positive pin of the big capacitor

Step 21 - Negative

Fix –wire to the negative pin of the big capacitor

Step 22 - Female USB

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

Step 23 - Test

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