WEEK FOURTEEN (2)

Bismillahirrahmanirrahim.

This post will be the last post for my project. I had done my Final Year Project for this two semester. And maybe I can do improvement for my unsettled project. 

There are a few recommendations for this project. First thing that need to do is make the gain of the amplifier higher. This will double or triple the amount of gain which is not enough for the amplifier for current design of EOG circuit amplifier. 

The second thing that I thought is maybe the horizontal and vertical plane need different virtual ground so that the current flow from the battery is enough to flow to the entire circuit. 

For this week, I plan to do design for my poster. This is my poster look like:

I also do the prototype for this project. Here is the prototype in the making:

soldering the components

make sure the circuit is not move in the box

I had received the TLV2472 IC but the IC is SMD type. So, I need to buy the adapter for the IC to fit to my circuit construction.Below is example of the IC SMD adapter. 

Barakallah. 

WEEK THIRTEEN (2)

Bismillahirrahmanirrahim. 

As this week, I felt very frustrated. The EOG project does not went well. Next week will be the Project Presentation for this project but this project did not run well. 

output waveform from horizontal plane only

output waveform from horizontal and vertical plane

The pictures were the output waveform of the circuit amplifier. As I move my eyes, the waveform did not change at all. Sir Syazwan, my supervisor finally asks me to do the circuit with no change from the original circuit. So, I need to change the LM358 IC to TLV2472A IC type. 

Barakallah.

 

WEEK TWELVE (2)

Bismillahirrahmanirrahim. 

I continue troubleshoot the EOG amplifier circuit. I had ask for the technician, I called her Kak Siti to recheck my circuit connection and she said the connection was okay.  I also buy things for my prototype. 

Barakallah.

 

WEEK ELEVEN (2)

Bismillahirrahmanirrahim. 

As this week passed, I troubleshoot the circuit again and again. But, I did not success at last. I also planned to do PCB for my circuit amplifier. Here is one of my PCB designed. I used PCB Designer to design the circuit.

 But, the PCB designed did not used as the circuit is not success.

Barakallah.
