    thats the purpose of a case imo. hahaha. to hide the ugly/messy wires. but of course, thats not the REAL reason behind it.

     

    :blink: Confused

     

    Wads the REAL reason? :panic:

     

    EDIT: Zzz... Failed again...

    Even though i made sure to solder super carefully, there was no sound at all, only when the tip of the jack is inside, then theres a faint sound...

    Sian!!!!!

    Oh, so for now i guess i should wipe stuff clean before soldering, been using the parts straight out of the plastic bag so far :)

     

    Edit: Doh' I realised one of the capacitors on the first amp i made was positioned wrongly, think tt caused the fireworks...

    As 1bit said, practice makes perfect. Words of wisdom here. Lost count of how many CMOY I killed before I got one working. So don't give up.

    Sigh at least it looks good, got 2 sets of components from Koba yesterday, ready for round 2! :grin:

     

    Edit: Crap, the uncle at koba got me the wrong VRs, would 50k still work?

    Thx for the tip :)

     

    Sigh, everything went wrong after i put it into the casing, some soldered points broke and the LED suddenly couldn't light up...

     

    I soldered everything back, then the amp worked for awhile, but fuzzy noise, then it blew out my earphones and i think the OpAmp smelled like it was burnt...

     

    Sian, gotta buy all the parts again and go for round 2... :shocking:

    Thanks :)

     

    I got a OpAmp, LM358N, and the dual pot. Going to wire up everything soon.

    Is it a problem that the LED is super dim?

     

    Edit: Dam, theres a super strong buzzing noise, and i dun really hear a diff in sq

     

    Edit: Sigh, the connections at the pot are all loose, giving me problems, hard to solder there...

    Waa :(

    Oh, wrong pot -.-

    Hmm, but whichever goes to earth doesn't matter?

     

    Hmm, but on williamneo blog, the po has only 5 connections...

    Can the earths be grouped into just one connection?

     

    Thx :)

    Umm, sigh gotta make a trip down to SLT again...

    When is federal open?

    you can order free samples from op-amp manufacturers. i got 3 x national LM4562 from national. why dont you check it out?

     

    just make sure you get the right kind. the DIP kind, NOT the SOIC kind. but then again, you can always get free samples of each kind. doenst hurt. haha.

     

    When you signed up, were you truthful?

     

    Anyway, how come all the samples no stock :(

    You must have sampled everything -.-

    Umm, need help...

     

    How do you noe which is plus or minus on the capacitors?

     

    The long end and short end...

     

    EDIT: Umm nvm, i think the long end should be positive, i think...

    Anyway its not like it'll explode if it's wrong :D

     

    Ugh, soldering near the ic socket is hard...

    Oh great, i got all he parts for the williamneo one, but no Op-Amp...

     

    I went round asking for Op-Amp at SLT, the ppl there just looked at me like i was an idiot, some asked "wad number" so i said AD8066, then they straight away say dun have -.-

     

    Walked super long but didn't get all the parts...

     

    Where to get? :(

     

    Thx for the recommendation on the sweets...

    I thinking of using the smallest i can fit the thing in, probably super large cos i'm noob at soldering...
