okay boys and girls I vol here again in
00:00:04.130 00:00:04.140 your gold recovery journey but in fact
00:00:08.750 00:00:08.760 today we're going to talk about
00:00:09.799 00:00:09.809 something else
00:00:10.850 00:00:10.860 it's another precious metal which is not
00:00:13.160 00:00:13.170 gold it's actually called tantalum it
00:00:17.720 00:00:17.730 happens to be more rare than gold itself
00:00:20.029 00:00:20.039 and goes for about eighty dollars a
00:00:23.150 00:00:23.160 pound so if you want to collect these
00:00:24.950 00:00:24.960 off your circuit boards you probably
00:00:27.080 00:00:27.090 will get more money than the gold itself
00:00:29.570 00:00:29.580 so tantalum is pretty much a very rare
00:00:32.920 00:00:32.930 precious metal that's pretty much in a
00:00:37.100 00:00:37.110 shortage right now in Canada but before
00:00:39.319 00:00:39.329 we get to the tunnel and capacitors I'm
00:00:40.970 00:00:40.980 going to just go over a few of the
00:00:42.799 00:00:42.809 regular capacitors as you can see here
00:00:45.979 00:00:45.989 basically these things are all over any
00:00:48.619 00:00:48.629 kind of circuit board and they have the
00:00:51.560 00:00:51.570 capacity to hold electricity so they're
00:00:54.200 00:00:54.210 like kind of batteries per se and they
00:00:57.080 00:00:57.090 hold different charges some are in
00:00:59.450 00:00:59.460 different sizes they come in all
00:01:00.860 00:01:00.870 different colors they have different
00:01:03.349 00:01:03.359 readings on them I don't know if you can
00:01:04.789 00:01:04.799 get that but the purpose of this video
00:01:07.940 00:01:07.950 is to show you what a tantalum capacitor
00:01:11.000 00:01:11.010 is and why it's so important and very
00:01:14.480 00:01:14.490 valuable so I have some in here actually
00:01:19.609 00:01:19.619 if you can see most of the tantalum
00:01:22.219 00:01:22.229 capacitors are going to be mustered in
00:01:24.679 00:01:24.689 color so pretty much yellow and they're
00:01:27.320 00:01:27.330 kind of small the reason why they're so
00:01:29.330 00:01:29.340 expensive is because this little
00:01:32.270 00:01:32.280 capacitor here probably has the same
00:01:34.670 00:01:34.680 amount of capacity to hold an equal
00:01:38.480 00:01:38.490 amount of charge to a ceramic capacitor
00:01:42.170 00:01:42.180 as you see right here so it also has a
00:01:45.649 00:01:45.659 much higher temperature so it can go at
00:01:48.260 00:01:48.270 a lot higher usage without leaking these
00:01:52.639 00:01:52.649 things here tend to leak and don't have
00:01:55.910 00:01:55.920 much of a long range use now so let's
00:02:02.359 00:02:02.369 take a look at these circuit boards here
00:02:03.950 00:02:03.960 where you can identify where the tandem
00:02:06.200 00:02:06.210 capacitors are they do come in different
00:02:08.020 00:02:08.030 shapes most of them happen to be small
00:02:11.809 00:02:11.819 square or
00:02:13.140 00:02:13.150 shape but this one happens to be a oval
00:02:16.800 00:02:16.810 kind of shape you'll notice them by the
00:02:19.350 00:02:19.360 color so if you see any yellow or
00:02:21.600 00:02:21.610 mustard looking capacitors they're
00:02:23.339 00:02:23.349 probably 10 on and I'm going to just go
00:02:26.460 00:02:26.470 through a couple of circuit boards here
00:02:28.410 00:02:28.420 that I have stripped this is a
00:02:29.880 00:02:29.890 motherboard as you can see I've kind of
00:02:32.330 00:02:32.340 pried it open but if you look closely
00:02:36.059 00:02:36.069 here there's one and they use these in
00:02:40.589 00:02:40.599 high grade electronics and computers
00:02:42.210 00:02:42.220 because of the size requirements so you
00:02:46.680 00:02:46.690 can fit a couple of these small tantalum
00:02:49.319 00:02:49.329 capacitors inside a cell phone where you
00:02:51.449 00:02:51.459 wouldn't normally have the space to put
00:02:54.020 00:02:54.030 them in with the regular size ceramic
00:02:57.690 00:02:57.700 capacitors so imagine if you had the
00:02:59.849 00:02:59.859 equivalent of these two capacitors here
00:03:02.129 00:03:02.139 which are made of title and put them
00:03:03.449 00:03:03.459 into ceramic your cell phone will
00:03:05.789 00:03:05.799 probably be five times the size and
00:03:08.309 00:03:08.319 that's the way they were back in the day
00:03:10.050 00:03:10.060 if you remember those old motorola cell
00:03:12.089 00:03:12.099 phones that were the size of the
00:03:13.379 00:03:13.389 cordless telephones that we have today
00:03:16.020 00:03:16.030 so pretty much that's what happened in
00:03:18.659 00:03:18.669 the advancement of technology these
00:03:21.089 00:03:21.099 tantalum capacitors have taken the place
00:03:23.759 00:03:23.769 of the old-fashioned capacitors so let's
00:03:27.689 00:03:27.699 put this board aside I'll show you some
00:03:29.970 00:03:29.980 other boards that we got here let's see
00:03:36.140 00:03:36.150 this one happens to have a lot of title
00:03:40.170 00:03:40.180 Amani so this was from an Apple computer
00:03:42.300 00:03:42.310 that I got and this is an older board
00:03:45.300 00:03:45.310 you can see all these chips so they're
00:03:47.759 00:03:47.769 pretty easy to identify if you just see
00:03:50.430 00:03:50.440 these yellow looking this one's got a
00:03:53.399 00:03:53.409 load of them and these are very very
00:03:55.589 00:03:55.599 rare and very very precious in fact
00:03:59.729 00:03:59.739 they're worth more than gold itself so
00:04:02.309 00:04:02.319 if you do see these on your circuit
00:04:04.949 00:04:04.959 boards do collect them if you want to
00:04:08.580 00:04:08.590 sell them they're worth $80 a pound you
00:04:13.140 00:04:13.150 can see there's more on the back here
00:04:16.310 00:04:16.320 they're all over the place they have a
00:04:20.009 00:04:20.019 capacity to hold a large charge let's
00:04:23.879 00:04:23.889 see what
00:04:25.590 00:04:25.600 so see as you can see that's a little
00:04:28.540 00:04:28.550 bit of gold so that tells me that inside
00:04:30.430 00:04:30.440 that ship there's going to be more gold
00:04:32.820 00:04:32.830 but let's look for those little
00:04:35.140 00:04:35.150 capacitors now we can find where what's
00:04:38.440 00:04:38.450 that well that's something else so let's
00:04:43.000 00:04:43.010 take a look on the other side know that
00:04:49.210 00:04:49.220 one you're gonna this one has right
00:04:51.250 00:04:51.260 there I can see that right now so if you
00:04:54.070 00:04:54.080 can take a look those little yellow
00:04:58.510 00:04:58.520 buggers are worth a lot of money believe
00:05:01.960 00:05:01.970 it or not and a lot of people don't know
00:05:03.190 00:05:03.200 about this so they just pass it by and
00:05:04.930 00:05:04.940 they only go for the main stuff on the
00:05:06.430 00:05:06.440 boards like the CPUs and the RAM and all
00:05:09.670 00:05:09.680 the other visible gold or silver looking
00:05:13.270 00:05:13.280 things but if you actually do some
00:05:17.410 00:05:17.420 research and find out what are these
00:05:19.870 00:05:19.880 little tiny things that are on the board
00:05:21.850 00:05:21.860 such as the monolithic capacitors that
00:05:24.010 00:05:24.020 have palladium and platinum in there if
00:05:26.290 00:05:26.300 you can take a look all these little
00:05:28.690 00:05:28.700 tiny boxes have platinum and palladium
00:05:32.800 00:05:32.810 and silver inside them and there's gold
00:05:37.050 00:05:37.060 that's used as a way to connect it to
00:05:41.470 00:05:41.480 the circuit board so it is time
00:05:44.470 00:05:44.480 consuming to take these out properly and
00:05:46.300 00:05:46.310 if you don't take them out well enough
00:05:48.580 00:05:48.590 they're going to actually crumple so you
00:05:51.520 00:05:51.530 got to be careful now look at this one
00:05:52.930 00:05:52.940 this is actually a kind of capacitor
00:05:54.820 00:05:54.830 that's different size it's not a normal
00:05:59.020 00:05:59.030 box but as you can tell that is silver
00:06:02.080 00:06:02.090 right there it has to be silver so if
00:06:04.810 00:06:04.820 you see a tantalum capacitor you will
00:06:07.090 00:06:07.100 know that there's silver connecting it
00:06:09.340 00:06:09.350 to the circuit board all the others
00:06:12.370 00:06:12.380 don't have to be usually the ten solder
00:06:15.730 00:06:15.740 has a very low percentage of silver and
00:06:18.010 00:06:18.020 the other elements but for the title and
00:06:21.400 00:06:21.410 capacitors because they're very high
00:06:23.020 00:06:23.030 voltage and they do carry higher heat
00:06:25.840 00:06:25.850 and the conductivity has to be of a
00:06:28.720 00:06:28.730 higher grade which is of course the best
00:06:30.730 00:06:30.740 conductor known is silver so this is an
00:06:34.630 00:06:34.640 old graphics card ATI card I'm just
00:06:37.180 00:06:37.190 looking for some title I'm here don't
00:06:39.820 00:06:39.830 seem to find any actually I found one
00:06:41.830 00:06:41.840 right there see there's why see anything
00:06:46.330 00:06:46.340 in the back and we got another one I can
00:06:52.030 00:06:52.040 see right there so basically you're
00:06:54.640 00:06:54.650 looking for anything that's yellow
00:06:57.300 00:06:57.310 mustard looking don't eat them I know
00:07:01.690 00:07:01.700 the mustard sandwich may be tempting but
00:07:05.380 00:07:05.390 do not open these up because if you do
00:07:07.350 00:07:07.360 they won't be worth as much you can open
00:07:10.120 00:07:10.130 one up to see what it looks like inside
00:07:11.950 00:07:11.960 I can bust a few open here maybe you can
00:07:16.150 00:07:16.160 see what they look like
00:07:17.280 00:07:17.290 close up basically the metal if you take
00:07:24.430 00:07:24.440 a look here so I'm gonna bring this open
00:07:30.490 00:07:30.500 to the camera I can find that there it
00:07:36.160 00:07:36.170 is okay so that's what tantalum is it's
00:07:40.240 00:07:40.250 kind of a blackish kind of looks like
00:07:45.430 00:07:45.440 rhodium so rhodium is also very rare
00:07:48.940 00:07:48.950 precious metal which also has a very
00:07:52.000 00:07:52.010 very significant value to it as well so
00:07:55.270 00:07:55.280 there's a lot of valuable items in these
00:07:59.290 00:07:59.300 boards I'll buy it they're in smaller
00:08:03.070 00:08:03.080 quantities however if you do the proper
00:08:05.200 00:08:05.210 research and if you have some spare time
00:08:10.680 00:08:10.690 instead of just watching TV or going on
00:08:13.570 00:08:13.580 the internet and Facebook and all that
00:08:15.190 00:08:15.200 stuff you can actually take a look at
00:08:17.680 00:08:17.690 your old computer parts that you're not
00:08:19.840 00:08:19.850 using and see what you can find
00:08:22.620 00:08:22.630 just for fun doesn't have to be a way of
00:08:25.090 00:08:25.100 making money this is just kind of an
00:08:28.270 00:08:28.280 educational cool way of realizing how
00:08:32.680 00:08:32.690 these electronics actually work all day
00:08:36.219 00:08:36.229 long people are in their iPhones and
00:08:38.050 00:08:38.060 blackberries and androids and tablets
00:08:40.659 00:08:40.669 and laptops and computers and TVs and do
00:08:42.730 00:08:42.740 we really know what's inside them and
00:08:44.890 00:08:44.900 what makes them work so it's kind of
00:08:47.160 00:08:47.170 very interesting
00:08:49.300 00:08:49.310 learn about these capacitors and as you
00:08:53.350 00:08:53.360 can see these different elements on the
00:08:55.750 00:08:55.760 board and how it all comes together is
00:08:58.660 00:08:58.670 pretty fascinating with the copper
00:09:00.970 00:09:00.980 wiring and the silver plating and the
00:09:02.980 00:09:02.990 platinum and palladium that's inside
00:09:05.140 00:09:05.150 these monolithic and CPUs and all the
00:09:07.990 00:09:08.000 other different parts of the computer
00:09:10.030 00:09:10.040 I'm still learning a lot and trying to
00:09:13.240 00:09:13.250 identify the different parts as you can
00:09:15.070 00:09:15.080 see here there's different types of
00:09:17.440 00:09:17.450 capacitors and wires all over the place
00:09:19.480 00:09:19.490 but at the end of the day it's an
00:09:23.050 00:09:23.060 educational experience for everybody
00:09:24.640 00:09:24.650 including myself and it does have a
00:09:27.910 00:09:27.920 little bit of incentive as far as making
00:09:32.200 00:09:32.210 a little extra you know coin as well so
00:09:35.590 00:09:35.600 if you do happen to have a stockpile of
00:09:37.960 00:09:37.970 old computer parts do look for these
00:09:40.600 00:09:40.610 small yellow mustard looking boxes the
00:09:47.380 00:09:47.390 older the circuit board the more you'll
00:09:50.740 00:09:50.750 find this happens to be an older board
00:09:54.310 00:09:54.320 so they required I guess more power to
00:09:56.620 00:09:56.630 power all these chips so all these chips
00:09:59.140 00:09:59.150 right here are being powered by all
00:10:01.960 00:10:01.970 those little tiny capacitors so it's
00:10:04.630 00:10:04.640 kind of basically the power supply for
00:10:09.010 00:10:09.020 the card so you have all these chips and
00:10:11.290 00:10:11.300 the power that's running all those chips
00:10:14.110 00:10:14.120 the data that's going to be going
00:10:15.430 00:10:15.440 through them is being stored in here and
00:10:19.750 00:10:19.760 formerly my board in the back you have a
00:10:27.310 00:10:27.320 few more so just look out for the yellow
00:10:30.910 00:10:30.920 ones they are worth some money and they
00:10:35.829 00:10:35.839 are very very rare if you do a google
00:10:38.199 00:10:38.209 and find out all about tantalum you'll
00:10:40.990 00:10:41.000 see some very interesting videos there's
00:10:43.570 00:10:43.580 a shortage of tantalum in Canada right
00:10:45.370 00:10:45.380 now and Germany is making a way of
00:10:48.790 00:10:48.800 refining tantalum and China is doing all
00:10:51.310 00:10:51.320 kinds of tantalum exporting and refining
00:10:55.420 00:10:55.430 so do some googling because this was new
00:10:58.840 00:10:58.850 to me as well as in really know
00:11:00.319 00:11:00.329 about 10 of them and it's kind of
00:11:01.789 00:11:01.799 interesting so that's all for now so if
00:11:04.009 00:11:04.019 you do see these yellow boxes on your
00:11:05.749 00:11:05.759 circuit boards put them aside put them
00:11:09.139 00:11:09.149 in a little container if you have one or
00:11:10.729 00:11:10.739 a little ziploc bag and here's what they
00:11:14.749 00:11:14.759 look like again close up kind of
00:11:18.650 00:11:18.660 cool-looking things don't eat them don't
00:11:22.249 00:11:22.259 feed them to your pets please do keep
00:11:24.679 00:11:24.689 them away from children because this
00:11:27.289 00:11:27.299 stuff is not a joke they can choke on
00:11:29.269 00:11:29.279 them and who knows what's inside them so
00:11:31.999 00:11:32.009 please if you do happen to take apart
00:11:34.759 00:11:34.769 your computers and other electronic
00:11:36.859 00:11:36.869 circuit boards do it in a safe area make
00:11:39.169 00:11:39.179 sure your stuff is properly stored away
00:11:42.199 00:11:42.209 from pets children and of course keep
00:11:47.809 00:11:47.819 your own safety in mind to try and wear
00:11:49.669 00:11:49.679 gloves if you can if you got a couple of
00:11:53.119 00:11:53.129 tools this tool right here is very
00:11:54.979 00:11:54.989 useful for taking those got past it
00:11:58.639 00:11:58.649 tours off of the circuit board or you
00:12:02.780 00:12:02.790 can get a chisel right here that's a
00:12:04.639 00:12:04.649 nice little chisel I picked up these
00:12:06.679 00:12:06.689 things just scrape it away and you know
00:12:10.789 00:12:10.799 a couple of other tools you have a
00:12:12.799 00:12:12.809 little pair of tweezers here and
00:12:14.650 00:12:14.660 anything else that may find useful for
00:12:17.989 00:12:17.999 you so that's all for now I hope you
00:12:20.329 00:12:20.339 enjoyed this video on tantalum
00:12:22.189 00:12:22.199 capacitors and put these little buggers
00:12:26.299 00:12:26.309 aside because they're worth money so
00:12:30.159 00:12:30.169 just keep that in mind take care
