Post 112
Today lesson was Digital Electronics, very hard!!! our tasks today is to make a digital clock signal. That right, from 0000hours to 2359hours and reset back to 0000hours. wires are normally stripped by the lab carers, but today is exceptional. and in the end, we needed more than 50 wires of all length and we cut it all by ourselves.luckily our faci understand the difficulty of today's task and leniently allow us to have a simple presentation. at first our clock signal was able to function, but not in a perfectly manner. my group troubleshoot and changing wires here and there and at last solve the mystery. a job well done said by the faci.
see how complicated our circuits was, to squeeze in 6 I/C chips and more than 50 wires to make a stupid clock signal...understanding test later in the afternoon, Communication Module. three questions, all problematic question, all need formulas to solved, everything in 30 mins time. managed to solve the first two questions, but my last question was ruined by without having a calculator. i need this inverse of tangent and i not sure of the function of the lappy calculator, 4 marks gone. steps one mark, answer wrong no marks. luckily KK was able to lend me his calculator and manage to solve the trigonometry question and carry with the next step. thanks KK, helping me to get back maybe 2 marks...
then after school went to Whitesands with my sister to buy my earpiece. just broke my earpiece again, mishandling by me... and she paid for my ear piece and my lappy cooling fan with her vouchers. thanks...
end my post here,
bowling tomorrow...
