★★ PCB Repetition 2: Cutting, Etching, Soaking ★★

dated September 30, 2011 (Fri) 

By morning, since our revised design was already approved, I proceeded with the cutting part of the unnecessary masking tape then with the etching, soaking and the smoothening of the PCB thru the sandpaper. That afternoon, I borrowed Jen’s photocopy of the diagram to be followed for the exact positioning of the components (i.e. diodes, capacitors, and resistor) on the PCB. Then later that evening, I attended our weekly campus mixer so I went home late again. And when at home again, I had to visit at my great-granny’s wake especially since it was already her last night and the following day would be her burial. So, Friday was fairly another unproductive day for our project. News again came to us that the following day, another typhoon would hit the country and the province would be badly affected since it was on Signal#3. üü
