WEEK 7(FYP2)- ETCHING THE NEW CIRCUIT USE ON THIS PROJECT

Objective:

1) To etching the new circuit at PCB board use on this project.
2) To replace old circuit into new circuit.
3) To make the complete circuit more compact and to save the space.

Analysis/Discussion:

During week 7, this project  is 80% done basically. I founded, the hardware prototype of this project is so huge and not nicely to look because the circuit at PCB board are divided into 2 which causes a huge use of space. The presentation day of FYP 2 at week 14 and the time is still long. So, I make decision to do a new circuit at PCB board. The 2 circuit will be compile together into one circuit at PCB board.

The etching method for the circuit are also same with old circuit. I only to follow the etching method step-by-step until end. After finished etching the circuit next step is to wiring all the circuit together with all component are use and the connection must be right. After that, the complete circuit was troubleshoot and the result is very positive where all the devices are running smoothly.

Conclusion:

Finally, the complete circuit for this project was done. The circuit look so nicely and so compact compare with old circuit. Next week is to focus build the hardware prototype for this project.
