Eletronics

Im sick of Electronics, i just spend 6 hours conducting our lab experiments, except we are experimenting failures more than results. We started at 10. Fixing everything, getting everything prepared, making sure everything worked before we actually start as there were some wire problems last week when we were doing ours. So our wires were fine after changing two, then we checked our signal generator, which went berserk when we turned it on. The frequency fluctuate like mad and refuse to stay on one frequency. So we changed that too. Then we got going. Conducting our experiment, until.. our lecturer came over to check our results. He pointed that our results are way out, and definitely wrong. So we fixed our circuit again, and showed him. It is definitely correct. He then claim the circuit has a problem, to our misery. After checking everything, he concluded our IC was spoiled, cause the output is 'clipped'. Great, so now our IC went berserk. So he gave us another and asked ur to try out before using it. AND the IC was spoiled AGAIN! We didnt know what to do. So our lecturer started to hands on. He went to try fix our IC. After an hour, he said everything is good. Asking what the reason he just said we changed many things, no idea what was wrong. o.O How unlucky can i be? What i saw was, our signal generator changed, the power generator changed, the wires changed, the circuit changed, not sure about the IC, basically everything was wrong. What a faulty circuit, with a faulty machine, and faulty wires, in a faulty lab and a faulty subject. Sigh....... So sick of IT!@!
