mtb856 almost lead u there.. Control Panel -> System -> Device Manager , find your arduino device in there, if its not there, check under ports and com... put on some screenshot when you are done.

This is awesome! Unfortunately it is not in metrics unit. BUT STILL AWESOME YO!

Thanks for the information that you gave, I've certainly learned something, a new IC for audio amplification OPA134 ( can't help but.. OPA GANGNAM STYLE :D ). However, I won't be building this system unfortunately since in Malaysia, lack of electronics component shop gives me a headache. But...

I'm not trying to steal other people's work, I just wanted to learn more and it is easier to ask a person who have built it himself than spending hours reading articles that i won't understand and unclear if it even works.. just an opinion :)

Yes, exactly! You've built one? would you mind sharing some information about the system you built?

This is an instant idea that I got right after i read an article about noise. Do you think it is possible to make an noise cancelling headphones by using the LM741. Except, i won't be amplifying the signal from the inputs (i can if choose to by just adjusting the varistor) but by using this op...

hah! I myself encounter this problem b4 when i started using arduino leonardo (which i bought it regretfully). So 1st you'll need to check if you installed you're driver correctly, because it is greyed out when it cannot detect your arduino. Would you mind telling what windows are you using?

can i ask a quick question? how come the equation that i got from my lecturer is Wo = sqrt ( 1/LC - (R/2L)^2 ) ? is there any different? i tried using your equation in my homework, but i can't get the correct answer.

Lightning strike--->positive streamers they said the lightning will connect to a positive streamer to "complete" the circuit. When a lightning strikes a man, do human produce positive streamers?
