Week without tutorials...

Well, din really finish tutorials... yet. Those ques can't solve 1 la... So can ignore... and if do too fast also useless, the 3 homework question for polar coordinates plotted dy, next week lecturer show another example then got all wrong... So i'm putting a neutral gear on my tutorials, just let it flow la..

Yesterday night tried to built a FM transmitter up, but failed...

It short circuit my new 9V battery to now remaining 8.5V... Waliao le... The battery seriously exp 1 lor... The battery hot till (luckily din explode, its 4am in the morning)

Basically today got a fm coil from car's alternator from my parents car service shop - Finally there's something free in my project...

I'm going to rebuild the FM transmitter again, removing those parts and re-solder to the board with a newly designed circuit positioning. And i've installed some programs to help me too... (Hope it can detect simple faults before i place the parts on the board)...

Still working on it, must finish it by today! There's 2 more projects on the way and test 4 is coming...


Built but got some short circuit le... Can't really detect fault... Just hope its not the transistor... RM3 le...

Now opting for software simulation before soldering...


DONE!
