Week 9

The final phone charger was completed. The final design was changed from the original. The exterior shell was removed. The charger was also tested. The first test involved shaking the charger before attaching a USB cord. After the charger was shaken for approximately 3 minutes the USB cord was attached to the charger and phone. This did not result in the phone charging. The charger was tested again this time shaken while attached to the USB cord and phone. This also was shaken for approximately 3 minutes, but again there was no charge yielded. This means that there was a connection issue. The problem could have been with overheating the diodes when they were soldered, the USB port was soldered incorrectly, or the connection between the coils and the circuit  was not proper.
