    MDR-770LP

    Anyone tried this yet? http://www.sony.com.sg/product/mdr-770lp Was thinking of getting this for on the go usage, but it doesn't seem very capable of noise isolating... Btw, found an interesting website: http://weloveheadphonegirls.tistory.com/?page=1
  2. Yup, quite sure everything is correct... Dam, tt means i got to buy a multimeter? Rather steal one from the school lab, I'm broke -.-
  3. Sigh, kind of gave up for a while, exams over now... Think i'll try again. How to tell if its a cold solder? I didn't take a pic of the soldering on the second one before i got pissed and melted down all the solder and screwed up the board. [attachmentid=4019]
  4. Confused Wads the REAL reason? 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!!!!!
  5. Hmm, thx for the soldering tip Oh, the insides are ugly, all mashed up...
  6. 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...
  7. Thx Hmm, is it normal tt the solder doesn't stick to wad i want it to stick to?
  8. [attachmentid=4010] Sigh at least it looks good, got 2 sets of components from Koba yesterday, ready for round 2! Edit: Crap, the uncle at koba got me the wrong VRs, would 50k still work?
  9. 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...
  10. 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
  11. Oh no, shipping fee required for national.com -.- Sian, its way more ex than any OpAmp... Oh, on here! --> http://bp2.blogger.com/_0URxOBSyTPQ/R4TeO0...0-h/Slide18.JPG
  12. 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?
