week 12 (FYP2)

Title: Prototype assembling and final testing on the prototype full operation.

Objective:

• To assemble the prototype.
• to test the prototype operation.
• to troubleshoot the problem occurs.

Activity:

This week activity is to assemble the prototype. The component of the full assembly of the project is from the Peltier module connected to the amplifier/doubler circuit. The output from the module then will be amplified by the amplifier circuit. The output from the amplifier circuit successfully doubles the value from the output of the module. The figure below shows the output from the module that will be double.

Peltier module output

The assembling activity that takes place, occur several problems, one of the problems occur is the student forget to snap a picture of the output value from the digital voltmeter. Hence, the proof of the promising result cannot be display in this discussion. After settling the connection on the module output and the amplifier circuit, then the student continue the activity on connecting the component of the prototype on connecting the regulator circuit. This regulator circuit function as it will regulate the excessive value of the voltage that came out from the amplifier circuit. The regulator also works as a circuit protection. This is because of the rating on the regular electronics devices are only require 5Vdc to charge. Thus, this can be proved that the regulator circuit function as to regulate and also as a circuit protection. The figure below shows the output after connecting the regulator circuit and the test is done.

Full operation with no load result

The testing activity on the full operation is done. The outcome that produces is promising as the figure above shows the result of the full operation of the circuit without the load given. The load in the testing will be power bank. The result with no load from the figure above, it shows promising results as the desired output is approximately 5Vdc. Next testing that going to take place is testing the prototype with the load. As the load given, the testing takes place. The figure below shows the outcome of the experiment.

Full operation with load result

The figure above shows the result of the experiment. The voltmeter reading shows the voltage value. The voltage that shows is lower than 5vdc because of its lack of power. This can be explained as the Power is equal to Voltage times current. From the information on the power, the current in this project is low and this is the cause the voltage is also affected. When the current is low and multiplies it by the voltage, then the power production is also low. This is the cause of the display voltage is not accurately 5Vdc plus-minus. Apart from the low power, this prototype is enough to charge an electronics devices and this method of having a supply out of the heat from the campfire is a brilliant idea to use as on the outdoor activity because it is impossible enough to have a supply to charge the electronics devices as it compares to the power bank, the power bank only store the supply and can be drained within 7 to 9 hour according to on how often it been used. From this promising outcome, the figure below shows the full operation of this prototype.

Full operation of the prototype

Conclusion:

To conclude this week activity, the objective of this week is achieved. Full function of the prototype is also a success to this project. The desired outcome of this project is required and from the discussion, it can say that this is a success for this "development of portable thermo-electric generator" project. This concludes the discussion in the making of the project prototype.
