Everything Disorder.

Sleeping disorder, eating disorder, brain disorder, mental disorder, nerve disorder many more disorder. 3 days since Sunday 13th October till today 15th October, Semester 2 engineering students stayed up late till the morning to finish and troubleshoot an assignment given by Mr Koay TH. Friendly speaking, this really give us the taste of real engineering life which I suspect to be much worse in real life. About the assignment, we are ask to construct a circuit that is able to display digits from 0 to 7 using discrete components, meaning not allow to use Integrated Circuit (IC) and 7 segment display (google it out if dunno) connected directly from the power supply from the 3 pin plug which is 240V, 60Hz from TNB. After careful planning, we found out that without using an IC we can really die because the circuit will be as big as my 15.4 inch notebook size. Phew... But then, we browse through the internet and found this circuit and do some modification to be OUR circuit. Hahahaha...

By looking at the schematic drawing is already cukup Cheem(Hard) d. Hahaha

After getting this circuit we got to plan how to arrange the components in order to build on the so called circuit board. That is where our soldering skill is put to test. This is where the problem starts, just to build the 1st part of the circuit nia aka the rectifier already give us a super bad reading. Many people burn the resistor, some burn the transformer, some burn the fuse of the three pin plug, some burn other things la. Due to the failure, we got to start the troubleshooting immediately. The best part is we all build the same circuit and we found out that the circuit is sexiest where only the female students will work and the male will not work. Can you imagine we spend 2 nights just to troubleshoot the bloody rectifier. First night, Marcus, Joel, Wen Ping and me stayed till 1 am to troubleshoot. 2nd night we stayed till 3.30 am and third night we stayed till 7am. Because of that i almost go crazy. Due to support from my friends, i decided to continue with the circuit or else i will give up. Furthermore this hardwork is just worth 2 marks in the overall exam but its the knowledge and experiance from this circuit make us learn a lot. Something we never get to learn in theory, in class and also things that we never expected aka "Magic". Hahaha...

Even after that, results of troubleshooting is we did it correct but there is no result. That is also another big problem. Joel, Wen Ping and Marcus circuit burnt a resistor, so they decided to rebuild their circuit. Joel and Wen Ping rebuild 3 times and Marcus rebuild 2 times. I somehow lucky again, instead of putting a 100K ohm resistor i accidentally put 10K Ohm resistor and it didn't burn at all. Phew... I seriously don't want to rebuild the circuit cos soldering ain't easy. Its damn freaking hard to control it.

My semi done circuit construction. Looks easy isn't it???

Lazy continue to type. Very sleepy....
