T-24 Lab Day

From today onwards, I shall keep a small log on my FYP progress for my personal reference and reflection of what I had done and what should be done.

1700h: Went to PCB lab at to look for Mr. Jalil to get my PCB board.
Cut the board, file the edges and drilled four 3mm holes on the four
corners of my board. 1720h: Went to the MacDonald's at engin with Weiyang, ate a strawberry sundae and a cheeseburger as teabreak.

1800h: Went back to my lab to solder my components on my PCB.
Did short circuit testing. All working fine.
Connect to my main PCB board (mainboard). Stopped work.

1910h: Went for dinner with Jonathan and Weiyang at Engin canteen

1930h: Did testing of piezoignitor voltage, secondary voltage of transformer, voltage of storage capacitor (o/c), voltage of storage capacitor (c/c), voltage waveform of dc-dc converter.

2145h: DC-DC converter unable to operate due to low input voltage from storage capacitor. Storage capacitor output waveform is correct when it is o/c. Tried removing decoupling capacitors from DC-DC converters but to no avail. Suspect DC-DC converter drawing too much current. Suggest to test with a linear voltage regulator MAX666 chip tomorrow. (Although very inefficient)

Time is running out~~yet still procastinating to press the "panic-button". Well someone said that in engineering no matter how worse the situation gets, things will always get done evenutally at the last minute. Somehow no one has ever refuked this claim.

----------- End of Daily Lab Log -----------

Small note: This coming Sunday is my cousin's 21st birthday still haven't thought of what to get for him yet. He's a Spurs fan...anyone have any ideas ?
