    What type of underlying (silver coloured) metals are used under the gold plated wire connector tips?I think you mentioned nickel,but could there also be silver underneath? Is aluminium used as wiring or underlying metal under gold plating? And is there such a thing as silver wiring as against copper wiring? 
    Also regarding gold plated wire contacts,if you cut the contact off ,is there a way to dissolve away any underlying metal,be it copper,aluminium,whatever,to just leave the gold behind.?As we know gold is unchanged under action of any one particular acid,although aqua regia will dissolve gold,but that is a combo of acids.Thanks ,Trevor.

    Friendly tone. Well explained. Got some great tips. Would like to see more clear video if possible. Well presented. Great Job and thank you.

    so these gold plated objects are 24k if I am understanding you correctly. NOT PURE GOLD. now my wedding ring is 14k gold, can I take these 24K gold plated objects and have turned into a ring. say for example I wanted to have a wedding ring made for my fiance’

    Please turn on Auto Focus next time. Trying to watch your video but its screwing my eyes because everything you move close is out of focus.

    Sorry but your comment about testing with a magnet to see if it is gold is wrong.  All gold plated pins and connectors that I have ever collected have been magnetic.  When I heat the pins off of a CPU I pick them up with a magnet.

    GENIUS …..I have a new hobby ! thanx

    Hi there,
    Thanks for all the advices you share on youtube. I find them very useful. Can you please make a video about what is gold in an iphone or at least let me know what are the key parts worth keeping. Is there any gold in the iphone battery connector. I work for a company that fixes iphones, ipads, samsungs, etc in London and i got inspired from your videos to start collecting all the golden bits and pieces. I know is not much but as you know …"gold fever" . I would appreciate any advice. Thanks a lot and i’m looking forward your thoughts on this.

    Thanks for the information. Now , how would you go about selling this as is, without separating the gold?

  13. Andrew Wilkins on May 30, 2020 at 4:37 pm

    Let’s say you had 20 grams of gold. 25% of it is gold plated and the rest is solid gold. If you melt them together will the brass or copper mix in with it or will it burn off and you’ll be left with solid gold?

  14. Owen Tripoli on May 30, 2020 at 4:39 pm

    is the gold connecters the only Gold to be found on a Graphics Card or does it depend on the model?

  15. Gary Speir on May 30, 2020 at 4:40 pm

    Thank you, thank you!

  16. Rajan Bajracharya on May 30, 2020 at 4:40 pm

    man u are so funny i like it

  17. ken dalton on May 30, 2020 at 4:41 pm

    Can i ask what do u suggest we do with it when we have collected up enough little gold plated pieces? 🤔 I’m from Ireland, just started out Makin jewelry, have recently been Collecting up gold plated electronics too, but I don’t think I could refine it down myself? What do u suggest

  18. Kenny Brown on May 30, 2020 at 4:41 pm

    Man Im glad this video discusses the two different colors of gold found on fingers. Just yesterday I started organizing an comparing gold brass copper colors …it gets confusing sometimes.

  19. Eric Nicksdaddy on May 30, 2020 at 4:43 pm

    Make a distinction between Electrical and Electronic, most Electrical is brass and copper, Electronic is gold

  20. SuperTuFue on May 30, 2020 at 4:50 pm

    Keep in mind that gold plating in consumer parts didn’t get popular until the 90’s. There are *many* boards that are still floating around that were cheaply constructed using copper contact. Test with nitric acid to be sure – gold doesn’t react (not apparently) with nitric acid, but copper would (almost) immediately turn green. (i say "almost" because in absolute terms there is a delay in appearance with any reaction).

    Interesting… but horrible camera focus…

  22. Justin Luedke on May 30, 2020 at 4:52 pm

    How do I know if I should resale micro chips or the relays or just scrap them all?

  23. newme58 on May 30, 2020 at 4:55 pm

    i have an older laptop.pretty sure 90s..wasnt working… i scrapped it it… has a metal tin thing cover over the cpu and it makes contact with the gold on the cpu board measures about 2×3 inches.. i rub it on my stone with 10k acid..and took about 20 seconds and disappeard  is it thin plated gold or brass.?… spring loaded washer things are gold colored too and the 4 screws that hold it in place are shiny… just like all the other magnetic screws in puters.. any suggestions?

  24. Shane R DiaZ on May 30, 2020 at 4:59 pm

    if its yellow its gold..? got it.. is that red wire gold?… hell yea…

  25. Subgenre Entertainment on May 30, 2020 at 4:59 pm

    I’ll teach you something. I do phone repair and on iphone 4 there is a screw that needs to go a certain length down or it won’t connect and allow your antenna to work in the phone. Very common starter repair mistake. But my point is that they most definitely use gold plting on nuts and bolts more then you think. You should test most stuff before you just chuck it out, you would be surprised.

  26. Mark Haney on May 30, 2020 at 5:00 pm

    Question and a comment, all gold carrys electrical properties so why would any body with any brains at all use 24 K the most costly best gold instead of using 10 K?

  27. VGA Guy on May 30, 2020 at 5:01 pm

    Where/how did you find that old board? I would like to get some parts from boards like that for an electronics project.

  28. joe spenoski on May 30, 2020 at 5:02 pm

    just find a honest buyer 2 tell u what each board is worth

  29. George Richardson on May 30, 2020 at 5:04 pm

    Generally manufactures have got better over the years in the gold components and Fingers/Pins in their items. and nowhere will you find 24 Caret gold, its normally 10-14 Car in the manufacturing.

  30. TheSoulripper6 on May 30, 2020 at 5:04 pm

    Sweet Video ty for this.

  31. Joshua Soanes on May 30, 2020 at 5:06 pm

    I noticed if you file down a wall plug connector it looks gold idk do you know if it’s brass or gold ? I’m really curious and a lot of pins also seem to be silver plated solid gold when I file them down

  33. Trev's Outback and Gold Adventures on May 30, 2020 at 5:09 pm

    Sorry ,one question I forgot to ask,the screw drive in DVD roms appears to be a distinct gold color.Could this possibly be gold plated,and why?…For electrical contact reasons?

  34. Tony Bonini on May 30, 2020 at 5:09 pm

    i have a question braords are different i have a board with a silver plateing i think but i dont know for sure  why some are silver or is it gold  white gold this i dont know what is it

  35. Wiz Kid on May 30, 2020 at 5:10 pm

    What about the actual boards themselves could they be gold plated,platinum plated,etc.

  36. tonymengela on May 30, 2020 at 5:11 pm

    hey that screw could quite possibly be gold plated, brass does not stick to a magnet, and brass screws are usually solid brass, some gold plated screws are used through the grounding system

  37. foxy2loxy on May 30, 2020 at 5:12 pm

    Brass is not magnetic. Neither is gold can you really tell?

  38. Salvatore Manna on May 30, 2020 at 5:14 pm

    b highly educational thank you

  39. Atheist Hindu on May 30, 2020 at 5:15 pm

    The gold pins which has solder on them are gold plated, and not totally gold. You can not find any open gold in a computer except for inside the chips. Everything else is just plating, thickness may vary.

  40. OnlyWatchism on May 30, 2020 at 5:16 pm

    How about flashdisk, memory cards, USB cable (cable to charge phones). Do they have gold inside them?

  41. Jason Beas on May 30, 2020 at 5:19 pm

    Is there any kind of metal inside the round batteries?

  42. Larry Robinson on May 30, 2020 at 5:19 pm

    That was not a transformer, it was a transistor. 🙂

  43. Hanafi Nyutnyut on May 30, 2020 at 5:20 pm

    very happy..

  44. Pete Friesen on May 30, 2020 at 5:20 pm

    Isn’t it easier to just use a magnet?

  45. urwisss1 on May 30, 2020 at 5:21 pm

    Have you heard about copper, brass?

  46. Daniel Tomaske on May 30, 2020 at 5:23 pm

    Electronic ballast have the most gold possible to find in a electronic

  47. Hank James on May 30, 2020 at 5:25 pm

    Thank you… I figured as much and will refer your super commend…. Hard of these days! ense

  48. bonnie smith on May 30, 2020 at 5:25 pm

    so if I broke off the gold I could sell it for gold at the pawn shop

  49. Nikolay Pelov on May 30, 2020 at 5:25 pm

    looks gold, should be gold …

  50. Mike Burns on May 30, 2020 at 5:27 pm

    Very good information
