This is a poratable charger powered by 2 AA Battery. All you have to do is connect the USB to you phone and it will begin to charge.
Electricity flows from the battery and the Bypass capacitors stabilize the incoming fluctuating voltage. The power supply capacitors stores and smoothes output voltage to prevent the charging icon on your phone from flashing on and off. The several resistors reduce the electrical current, preventing the circuit from burning out. The inductor induces a magnetic field, amplifying the voltage from 3 to 5 to meet the demands of the charging item while the boost converter acts as a on and off switch for the inductor. The Diode directs the energy flow to the USB so the electricity can flow inot the phone.
In my time in Blue Stamp Engineering, I was forced to be more independent and to use my own strange and resources rather than relying on others. Normally, I always get information from others In my time here, everytime I asked a question, the staff would say, “Google it.” This WA schallenging for me and was a great learning opportunity for me and good practice for the real world.
