  1. hmm interesting. maybe a candidate for FYP. Polymer with ultra low dielectric constant for audio cable insulation :D
  2. no worries. we all make mistakes. most important is learn from them eh. thats wat discussion is all about. BTW: i was wondering y teflon insulation. Does all wires uses teflon or only the high grade cables uses that? Cause i remember my prof mentioning that teflon is expensive and thus no such thing as teflon chair ( i actually suggested that lol )
  3. nope. you dun count like that initial: S has oxidation state of +4 Cl has OS of -1 H has OS of +1 O has OS of +2 Final S still +4 Cl still -1 H +1 O +2 so again there is no oxidation no reduction counting oxygen and H is a very primitive way to describe redox the proper way is to count changes in oxidation numbers. anyway lets leave this chem discussion here. this is about teflon wire. no oxidation states. pm me if u wan to discuss further cheers!
  4. which 1 is reduced which 1 is oxidised? this is a neutralisation process. no oxidation no reduction. i dun get wat u trying to point out
  5. thats is called an half equation in this case Na is oxidised to Na+ there will be a subsequent species that will be reduced for eg. Cl Cl + e- -> Cl- thus when u combine 2 half equations u get Na + Cl -> NaCl to put relation to audio copper react with oxygen in the air. Cu -> Cu2+ + 2e- (oxidation. Cu from 0 oxidation state to +2) O2 + 4e- -> 2O2- (reduction. O from 0 to -2) thus : 2Cu + O2 -> 2CuO they are half equations.
  6. mind enlightening me to a process where there is only oxidation/reduction and no subsequent reduction/oxidation? personally i havent come accross one and it will be good to know more thanx
  7. when there is an oxidation process, there will be a reduction process. they occurs in pairs.
  8. i quote from wikipedia http://en.wikipedia.org/wiki/Redox
  9. just to point out loss of electrons = change in oxidation state. so milkpowder is correct in that sense eg. Na - > Na+ + e- Na change from 0 to +1

    LDM+

    if i remember correctly, assuming no revision is done on LDM+ no light on the amp itself. the light is on the charger and it does not indicate whether its fully charged. i.e the led will be still on when its fully charged
  11. Just received USB Monica2. can hear more details in the songs. Sound more lively. Shall ask my bro to compare with his Monica2 without gain stage when he gets back In audio heaven now.
  12. to make it white. use a white crayon and colour over it. some crayon will be "trapped" in the wordings. clean off the excess with alcohol or something. tts how they make arcylic name tag at beach road.

    Ipod LOD

    i bought 4 pieces. cost me abt $5 per piece including shipping

    Ipod LOD

    http://home.swipnet.se/ridax/connector.htm i ordered from here b4.
  15. nice. now its a matter of scratch protection. I was thinking, perhaps we can coat it with some transparent layer. if i remember correctly, modelling enthusiast will apply a layer of clear coat over the model when their paint job is done. This layer serves to protect the paint. Now i wonder if a thick layer would help prevent scratches on the arcylic. Any ideas? Corrosion shouldn't be a problem as these coating are applied on the plastic model.
  16. actually if u all dun mind having an arcylic panel, there is a guy in hardwarezone forums who has a laser cutting machine. i dont think the design should be a problem. the only possible problem is the countersunk hole. is a counter a must? the link http://forums.hardwarezone.com/showthread.php?t=1088877

    Thumb screws

    try SLS. some shops do carry. Esp those who sells fanciful fans and cathode tubes. sorry i dun know the specific shop though
  18. i been using iTunes. its quite good. just switch off all the sound "enhancing" options.
  19. could it be the stock IC? any1 tried another IC?
  20. a headamp can do wonders to ur MS2 despite the low impedence. i own the MS and i can tell the difference with and without amp. u might be interested in this. http://www.sgheadphones.net/index.php?showtopic=5084 its a dac and a tube amp all in 1. just that its not that portable though.
  21. i think i will meet u at woodlands. can go pick up some flanges from stereo
  22. just sms me when its ready for collection. I am fine with paying the extra cost. u are doing us a big favor for this MO and its unreasonable for u to incur the extra cost.
  23. they are with u now haxyer? wee... finally here
  24. yeah man. i was like.. wat the...? haha did mr yang send a cortainer or wat
