Tittle: Capacitor is used to make the current and voltage increase

Content:The problem is the output current from the generatot is too small which is 0.005mA.From my research,the capacitor can be used to increase the output current by its charging and discharging method.Below is the circuit of the charging method by using the capacitor.

The result for this method is not really obey my objective because when come to the discharging process it have and infulence the number of voltage.The detail explaination I will come out in the report.

Tittle: TESTING FOR THE BOOSTER CONVERTER

Content:There is various type of boost converter.To choose the suitable converter,we have to know the maximum output voltage from cooler fan then we can choose the range for the boost converter.For my project,the maximum output is 0.5 Volt.The obejective of my project is to get 12 Volt output voltage.Therefore, I  have to find the range of boost converter between 0.5 Volt until 12 Volt.

From my research,the near and suitable boost converter for my project is 0.5 Volt until 30Volt.Below is the picture of the my suitable boost converter.

Tittle: Result for testing the maximum voltage that can be produced by the cooler fan

Content: I am using 2 cooler fan which is similar in size.(15cmx15cm)The first cooler fan is connected to the power supply directly.The second cooler fan is put near to the first cooler fan.The output from the second cooler fan is connected to the multimeter and the reading of the maximum voltage can be produced  is 0.5V.Below is the picture of the cooler fan.

Tittle: Searching about the component

Content: For this semester,I have to do the prototype about my project.I have already survey about the main component that I have to buy to proceed with this project.Below is the list of the main component.

1. Dc motor/generator
2. Fan
3. Booster circuit
4. Arduino
5. Voltage divider circuit
6. Resistor
7. Switch
8. Wire
9. Polystrene
10. Board

After surveying all the prices,I am starting to buy the all component for testing about how much of maximum voltage should be produced by the fan.Next week i will explain about my result.=) stay tuned.
