The diyMod: Ultimate Audio or a Dead iPod

Monday, June 2nd, 2008 – running time 31:05
The diyMod skips the headphone amp in your iPod to get pure audio straight from the source... this is one of the toughest mods we've ever attempted!

In the tradtion of Epic Failure on Systm... the diyMod, an audiophile hardware hack for the iPod, doesn't really rank. We -did- have it working. We just couldn't keep this slick Do It Yourself take on Red Wine Audio's $250 iMod running long enough to properly test it. Or get the sacrificial iPod Nano buttoned up again. (It's not dead, just a bit... naked.)

The buzz around this mod for the iPod is pretty huge. Why? Many models of the iPod contain a Wolfson MicroelectronicsWM8975 CODEC. This chip converts the digital audio stored on your iPod's drive into the analog audio your ears can hear. Serious audio geeks believe the WM8975 does a spectacular job.

They also tend to believe the amplifers on the iPod don't do a very spectacular job of making that sweet sound loud enough to hear on your headphones.

The solution? Bypass the onboard amplifiers in your iPod and run the audio out from that Wolfson DAC to a quality headphone amp or your home stereo.

In this episode we make some spudgers so we can crack open a couple of iPods, solder with the tiniest wire we've ever used and get all kinds of excited. (That 30 guage wire might have been the problem... Patrick's working with some sturdier stuff in a new attempt to make his diyMod work for more than 20 minutes!)

Spend some serious time reading The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G!. Joneeboi has done a great job getting the info together on how to do this... but, as we learned, the difference between reading about this hack and performing it is pretty major. (The thread is over 113 pages long... lots to learn there!)

Opening your iPod is the easy part: iFixit's Guides are your best friends if you're opening an iPod. Or an iPhone or a Macbook/Macbook Pro... they sell repair parts, and they're the best step by step instructions we know of.

Inside, you'll be soldering wires to SMD: Surface Mount Devicesso tiny you'll be begging for a magnifying glass.

You'll need to modify the iPods headphone outputs or Dock Connector, to get the audio outside the case.

And, of course, you'll need to put the whole thing back together, and fabricate a cable with a pair of 47uF capacitors between the iPod and your headphone amp or preamp.

Patrick's still hammering away on this one, 'cause he wants to hear what it sounds like first hand... he's also

PS: if you spend a lot of time listening to music through headphones/earphones/earbuds, the Head-Fi.org forums are awesome. Go check 'em out!

PPS: Let's be clear: this is not the iMod, that's something Red Wine Audio does for $250... and judging from the look on Patrick's face while he was working on that iPod nano, it's $250 well spent if you don't enjoy starting at tiny parts until your eyeballs are ready to fall out of their sockets!

" The subsidy system is brought to by the united states air force Microsoft unified communications and go to -- dot com. You might know that many the models of the iPods or some pretty solid high quality to actually digital analog converter he's Kodak's -- that digital audio on the hard drive into the analog audio your ears can understand. Unfortunately the amplifiers and headphone jacks don't do a great job of reproducing equality for your headphones. -- they -- gonna look at that I why -- the Apple the why not let you bypass the amplifiers on the motherboard here and directly connect the output in those digital analog converters to give you a much better source and that means better audio file quality. Come and and your iPod coming up today on system. What in the system I'm Patrick Norton we didn't have enough. Last week -- little tiny wires and where weight on the pile parts to refurbish might. Baby savaged iPhone so in the meantime we're gonna give you the DIY not just for fun we're gonna hack into an old iPod. And deliver with a lot of people considered the ultimate audio file hardware hack for an iPod use for the external amplifier somethin' like -- where is that they headroom amplifier gotten this case here. Let me make this clear without us like that you want -- example headroom -- for. You gonna boost through some kind of external amplifier this will not work with your headphones you can use it as a line level output. To your stereo this was inspired by the -- pretty cool -- from red white audio and the idea is that fourth or fifth their fifth and a half generation iPods use Wolfson microelectronics Dax. The W and 8975. To be more specific -- high quality by consumer electronics standards there what turns the audio basically the digital audio there's there's ones and your hard drive. Into basically the wave form that you're years can actually listen to of that check this out in the chart that was components for most models and you notice something. A lot of the iPods actually have some pretty slick parts inside of them. Then I -- I even if the fires of on the board aren't so high I mean basically you're talking about little tiny chips that are cramped inside. Of your iPod the -- bypasses the answer did you direct output from the facts on this particular nano something that the folks at some -- went on you don't mod. That's our deck right there and those little tiny thirty gauge wires or Saturday in the outputs -- actually pull the signal on the right is that you. Along with those not so good opting to bypass the problematic items -- capacitor is resisters service not components are really sophisticated they tend to be. Inexpensive not necessarily the best. Option for audio file great audio the other thing is -- a shorter path can also basically fewer components can definitely clean up your audio signal. Having gotten my folks are red -- audio doesn't feel other models are worth modified. They figure that acts in other iPods aren't worth it it's a 250 dollar hack if you ever want audio do it RC 250 dollar professional modification. If you ever going on -- doing and it's well worth it if you have excellent source material lossless audio files and you run with an external amplifier. And you don't put a crack open your iPods or soldering this is not for the faint of heart. Now if you want to get hands on the fine folks head -- out or have an amazing resource for getting your audio directly out from those acts. But by Johnny boy who started in monster thread called Apple DIY mod my take on the famous -- mod featuring three G four G five. And the -- one G these people have put together in amazing resource complete DIY instructions and they also want to point out that this is not the I'm not this is their own version of way to get the audio from those Wolfson Dax. How to somewhere you can lead to an amplifier. And it's really not for beginners -- yes it will most definitely violate your warranty when you're cracking the case and soldering things down. Say goodbye it's not that your warranty period I think twice about this and if you're not willing to screw up. And break your iPod do not do this -- let's talk about the tools are gonna its primary tool is a spider to plastic or metal object basically took the -- used to pry open the case. You're gonna need a pair quality 47 -- capacitor Unita Saturn are with a small tip -- need to be adjustable then do a very low wattage reluctant fifteen. -- soldering iron. -- a light to change. A filtered Jewelers screw driver very steady hands and doppler dock connector you -- mod the willingness to break your iPod. Let's go over sort of 32 version."

" How this goes together we're gonna crack open your iPod. We're gonna get to the tax we're gonna -- a little tiny wires to a source from attack we gotta give the signal care on -- as little tiny wires away out like your headphone Jack or your dock connector. And yeah we've got to figure out where going to put this caps in the lines most likely in a doctorate dock connector outside your iPod put it all back together. And remember this requires an amplifier between the iPod in your headphones or you can use it to power. You know your amplifier in your home stereo. Remember if you're not ready for this watch than video don't start this project because this is pretty hardcore. Let's start out -- opening an iPod whether it's something like this little tiny iPod."

" Now which is this. And this. It and this or something like therapy and is busted up I think this is a second or third generation iPod they can third generation. They're pretty much a couple of things that are standard. They'll have a plastic topic contains the control mechanism or scroll wheel and the screen. Andy stainless steel back which is both solution and you probably hurts like -- I turn it towards the camera. That in between these two is a joint which is basically what you're looking for so -- tiny brightly visible line in between the stainless steel and the plastic. Okay we -- you -- basically we got this budget we made you got this budget box might fix it wherever it came from -- crack the iPod this is always terrifying moment right so you're looking for the layer between plastic and steel yet this budget that -- Angeles reports you mean. Gary Payton. Actually actually an -- doesn't -- if you don't get America one library TV. It's he discovered in the fridge in our offices. Apple got me back and upset if you want to approve what's your really not scared trying to think you're gonna bring the founder of the."

" Yes I'm going to bring the thunderbird -- one thing about this it's ultimately -- I mean I'm a little. When your little home in resolutely Apple now what actually little that gum -- little Apple juice box need."

" I've seen them around behind my time to understand that basically a chemical engineer originally came in here is basically Apple just concentrate. Instilled if you haven't seen it you should really watch your your getting into when it was someone's court yeah digital personally bucket the bucket makes it walk -- over here and I'm gonna get a few things that brought -- okay. Thanks -- you know you gotta spit right yeah I mean credit to spit on -- community it."

" And applicable -- you can check."

" They're normally you you drink lines of the civil and usual for you didn't. You know born in Russia. Simon grew up -- my -- pounding out a bucket of -- one of the only people didn't like immediately -- is essentially a little lighter than ever clear it's like 18070. Proof."

" Problem -- I've completely become -- magic and yeah. I'll blow everything out you know dot com. It's it's a lot cleaner than I expected. You know given Netflix such you know national did you guys are pros and its thing it's certainly believe he. Yes I mean you know it's got some nice round this on the back end of the Apple little Greg -- kind of feel going subtle and I liked the cleanliness of it. It's if it lets us practically pure alcohol and input it's clear I mean you don't have ever cleared we went a catalogue from botnets and and then rubbing. Koppel -- and it's got a little bit more complex and look at that -- kids com. It's. You know I'm wondering you know actually the result kind of like -- I'm imagining you know getting a nice little package -- beautiful logo on it maybe don't have -- And you can over the world system the Apple Jack and geeks everywhere I mean you know from grey -- we'll just take over -- like Ohio."

" But the thought about Kristall anymore -- Apple Jack. Give me a -- and while leveraging the argument June 23. -- So let that ultimately we should put that -- is all about bringing wind to the people like fruit fruit uptight -- nobody can -- Gary. Not your voice you're gonna let's get back to cracking open the iPod to me to get -- good -- that. Let's take a moment to thank one of our sponsors the united states air force. --"

" It's."

" Hey you know what we actually see how we made our sponsors when we do this one -- hide from theory into. With the back of the workshop we'll see -- we made this budgets crack this open and get this mod finished. All right -- back to the workshop again. And we're talking bass Rogers right what's this Roger roll okay telecommunications tool plastic keys for like moving wires around your -- in a closet our case basically. -- Anfield this page look at it right now I fix it dot com Donald they have an incredible source of giants for opening up iphones and iPods. And no one."

" We call those things Mac books and science. They sell lots and lots of tools primarily plastic the spider the heavy smoker and an analyst Roger. So you can purchase a sponge like this are available all sorts of us sites on the web for like 2345 bucks. We went with a little DIY action we actually have the fabulous. Six piece many chisel set we've found and the quality on this is atrocious. This is basically bad Indian steel by. It was a perfect tool to start out with -- give -- a nice kids to play with and we did a little bit of customizing. With our friends in the Emery paper yourself what do we do busily sharpening ads on that the tools started out with a pretty. Ms. double -- ground little bit on the wheels."

" The -- take up a little bit at a time. Can -- events."

" Glacier -- deliver rolling on the top of that we're gonna reduce the rest that with a little bit. Emery paper. So. So -- paper here that really matter I think or use and what's this like 800 -- we have some two point humor here cute when he's gonna basically take more steal off faster. And we want to -- is mixer. Get a nice clean reasonably sharp edge. And we're taking it extra that metal off of this and so plastics Rogers. If you want T actually make 18 popular item for making plastics -- would be in nylon. Chop stick or an old toothbrush. Any advantage of the plastics pledges the reason why they come in most battery replacement kits and stuff. Is because they're not gonna -- the plastic. On your iPhone. So move we got that toothbrush head cut off there and he we're gonna take our friends at the Emery paper. Basically want to nice stiff edge on that -- he had done that. Pretty in. And another something the steel ones are less likely to you more your iPod. Or the ST -- plastic spiders are less likely tomorrow your iPod. The steel ones are -- a lot easier to get."

" Under that edge -- we're doing here is your crack in. Basically -- split and they use this budget just put the space between the stainless steel back in the plastic front and then that you are waging an open again. So until this space there. Want to -- care you don't want to basically like -- can on this but what you do want to do is get he. -- Trashing Emery paper and away and then. You know we get these little senator. Julie picked up for five bucks isn't that cheap pair of about tweezers we split in half. This has a nice flat spatula and like that that's essentially that's a -- budget they -- is essentially a dentist's. When they called it not -- any. Specialist. And you know work that into the edge. Then basically want to like not -- thing and once you've got it in there. You basically go around and released the plastic connectors there's this plastic clips. And mostly when this pops open in the second. You'll see that -- and there is a series of metal clips on the inside this iPod back. That the plastic see these plastic clips here it is just happened place and that. Now if you -- the case little bit when you pry open which is really no room do not panic buying a sort of hard edged object put this piece of plywood here in just her role that edged back towards blacks and you see some kind of straight edge for example -- some rod here. To make sure that edge. Basically you know if you get any kind of -- here is -- smooth back down that we have a nice clean -- this is a pretty old pretty. Abuse iPod but the -- is still looking pretty. Not damaged."

" From our crime. Although it is a little stump fields so -- knows what -- in his pockets of this. Not only do they sell replacement parts for your iPod or iPhone or even your MacBook and MacBook probably have these very very excellent I fix it dot com slash guide and -- hear they're gone for Macs iphones and iPods or click on iPods. And look at that so the first generation iPod original the second generation third generation and at this point I think we count me. Third generation. Don't leads the other have well yes and what it'll do is basically telling you. How to open it up it's the component want to repair or replace in -- case what we're actually looking for is essentially the logic board -- access the larger ports that we can solder. Things do it. How to we know this because of that amazing Apple DIY mind thread. And if you go to that gigantic first page and that's I had five. Dot org webpage it has a huge table of contents that lists all of the models they have information on and you basically schooled now. Until you find your model so. You -- on second undefined network. Alright so basically issued here we cracked open not -- it is speaks clearing -- dead third generation iPod and which okay it was a fabulous experience and one of these you notice something is lots and lots of tiny preachers would quote screwdrivers for security drivers in there. Began. This couple -- down here and restore point that's a pretty much going to have to take all those apart. And notice especially the earlier ones they had pretty good size connectors here. Joining everything together the yeah. The jacks on there. What's it look at the product we're actually -- obviously this is already opened the kids in a fit of pique I decided the ceiling actually -- this thing together. Now look at the screen right now we're gonna they had -- that work. The thread on this one. What you're looking down is the top of being and no one G that's a pretty. Excellent example what you might find in that thread that lets you know where you can tap the audio out from that Wolfson microelectronics. -- And you know those little tiny whatever those things are disease on them look huge right well. -- You're closer to those in real life. The united how small those are that's thirty gage -- attached to the us. So let's just say the bigger the iPod generally speaking -- less. Painful lead -- reestablish going to be so I mean you're basically talking abouts. Some horrible connectors so this is that this is to of that connector on that third generation iPod right there. And the equivalent connector on this one is something old. Like. This and they know he'd seen that little ribbon connector next few my index finger. And what's really great you have to disassembled -- Underneath based -- this is over -- so. You're gonna have to do a whole lot of horrible stuff the -- fix it dot com guides are excellent for telling you how this looks like if you just template but if you're not comfortable moving. Little tiny wire little tiny switches is -- to release these ribbon cables. You've got to reach."

" Underneath that cover. And the flip. And looking even see that little black leader right there. That legal rights yeah plastic spiders are really afraid of damaging. You basically slide. Your -- and in this side and then when this is flipped down. It lock down that. Hopelessly obsessed with nonbelievers said puppy that are. Even look at that they're gonna and that's pretty much the action on this little tiny ribbon cables so maybe starting with the nano was not -- brightest idea. So. You can see be little tiny bits of sun that are willing to stand here spark fun. Dot com actually has -- pretty excellent guide."

" Q soldering service -- components and a lot of what they have had caught on there is kind of a neat go forward attitudes are they love. Yeah every this off the website because it's just that fabulous. Tools you absolutely must have a fifty dollar more soldering -- soldering -- and solder and that is always easier to work with soldering Wiki -- this reports also called these soldering -- what they basically use this is is to jump opinions if you've gotten too much solder connecting bunch of little tiny pins. And it of the top of that spark from web page. That's a typical connector there looking at a fifty pin connector for an -- that is made probably something it makes the thirty pin dock connector. Look pretty reasonable by comparison. So you'll -- be -- this earlier son. Fairly. Narrow -- are like gay solders to tailor these two pieces tolerate here. So this is like points or five inches in diameter is his point 32."

" The bigger the solder is more when this is gonna be to work with on these little tiny parts so. Pony -- spend the money even for lighter engaged and then the one I'm holding up here. This don't even bother trying you're gonna have a nightmare of a time."

" So the good idea exactly how small and 38 -- is and actually to talk a bit more about what her -- and it's more -- is to. There are big fans of using hot air we were working if you're working with service not components and hey it's a great read bullets that -- This shadows. But to give you basic idea unity is you don't make mistakes you can pretty much hotter with a --"

" Herndon and some -- but the idea exactly how small thirty gauges. The wire holding up here. Is a point four -- wireless to the wire found inside of a single wire inside of your ethernet cable. And right next to it is the thirty gage wire and maybe even come close to see -- those are secret yeah. And when you start soldering these things you start thinking about not drinking caffeine and moving far away from the part of the house it's migrated every time -- the Oscars."

" Yeah it's. Heart before we move on we have to think one of our sponsors these people a -- with a week after week isn't go to any dot com and we got to go to special deal for. Now you make an impact on line was a favorite do with -- dot com dot com names as -- a dollar and 99 cents world class -- my wife uses it for all website. Fast and easy website builders and quite a bit more. If you keep your personal information hidden from spammers hackers and -- permit -- stocking you since grad school. Private domain registration from go to -- dot com is gonna protect your privacy by keeping your address your phone number and more and who is database plus. Here's the deal theater includes students SYS two when you check out you're gonna -- an additional five bucks off in order thirty dollars or more -- restrictions that apply to -- the details on the website. Do us a favor here assistant teacher he's the Internet and go to any dot com and use actually asked to SYS -- this too when you check out."

" And support us by supporting them."

" So this is 38 wire wrapped wire it's available at your local RadioShack pretty cheap and we pick a couple -- that the -- and so. Just for fun and you prove that I am as least as dumb as -- look. One ID solder one of these insiders back down. And chances are that'll never actually be able Saturn back on again oh and I'll hold these actually just like fifteen Yorker Klein tools wire cutters. Or wire strippers that they sell it home -- possibly of those places like that. And they are spectacularly. Good for stripping smaller wire they basically have. Guides for solid stranded wire again thirty gig solid thirteen stranded actually. It makes it. -- daily ease of use. So -- you'll be -- A lot of it has tips already got my opinion. Basically spent a lot of time with every paper and locks and managed to revive what was left of carp beat up soldering iron -- last week. And lets you pick -- completely insane we actually do it if fairly good reason for on soldering iron piece out of one of these wires which is that. -- opening red wire on the right channel now which is. And that number 53 -- computer easy you can."

" Before the ones are specified for this every you know and that's -- and that is the amount why are actually worked with initially -- that down there."

" So if you think you've got a little this -- we don't we're gonna pretend you're from moment to think it'll over the solder jumping between those -- What you do is take your salary when it."

" And literally and I like to thank the fine folks its work fine for this tip this that is laid down there. And heated up with the side of your soldering iron and good gently on that -- likely pick up. And remove it before -- actually pick up the extra bits of -- down there."

" I hope would have been completely scorched the board but we're gonna take. In a -- Aaron there. It's. A -- ten heck yeah and second order has over thirty gage wire. And I gotta say this is horrendous stuff to work with because it's just so fine. We're gonna basically a -- this until we see it's not king -- news obviously. And schooling this earlier. -- And recycle that it's just nice chunk of wire. So is good to have more -- you can be released Saturday this done and be like -- no. Or as the but we'll Catholics say it only knows we're gonna take a little bit of little tiny bit probably even less than that true than than all. You see the tiniest bit. Clear wire on the and I don't -- orthodox but I -- a lot easier to work with. -- that was ten so. It's pull this masks back together. Make sure the have to check at this picture we haven't managed to solder -- that but I found it was little easier to have the wire pretends. He then up. Animal -- that could retain that. Okay here's the moment of truth or my final opportunity to completely screw this board once again. So remember we're going for pin he 53. With a little tiny had who simply has no side are right there. It's. If you go for the highly elicit a little bit of -- on the end of your soldering iron method. I'm pretty sure those of you who do this professionally or wincing right now but it's been working for me so. Actually gonna travel in a little bit more wire off the end of that. So we will get a wired there. Consumers to work when it. I really decided that or completely screwed up."

" Now we've got our little thirty gauge wires down on here we've checked. I'm pretty sure I haven't jumped to between the two tiny little circus not connectors -- happens. I'm everything's critical aspect and I think we're gonna do is actually end up. Connecting aren't wires for the right and left channel and of course when you ground and virtue you need dock connector here right. Sounds good want it though before we button and back up or when things and making it more permanent which means unfortunately that little tiny ribbon connector. And that unbelievably tiny ribbon connector need to be put into these two little ribbon connector -- yeah. Them every uber means what to call us. Basically I -- reassert those in England there. Lots. And that's not going to be approximately -- we can make it happen without. Permanently damage in anything on the right. Basically this is declined point -- which were horrible here. Did operate with the yeah. It out of power so. -- openness that actually had to do it can't be positive. And alert to her. Just refer to our needs only -- loose wires if we can give me. Analog outputs be created to work record button thing I'll take this out of these."

" Yeah it's."

" Went through Google oscars are definitely over this project. --"

" You know it's time take. A message from one of responses into the people who help us bring the show it to you today. Microsoft unified communications. They you can transition -- with a software solution and still get all the benefits of unified communications without having to rip and replace any hardware you don't you PBX. Now not everybody company knows about this technology in some IT guys are gonna extreme lengths to protect their hardware check out this video from Microsoft. And see just how far one man band is one you're gonna break his speedy action being -- replace. You've heard people protesting outside corporations find out what happens when a protest goes into wars."

" It is yeah."

" powered up it's playing we have put back together yet but it's not dead. Good science and and remarking about those little or not and I saw this evening it audio out of our cool guy. Line now from need to act which is. Played without first checking yes so. There right now in my network cable where you tell thing counts so it's good to grab -- yeah. Regular old stereo headphone cable. Hand. You guessed it -- is right what is left. That's little -- out of the music and the the common market to them that."

" We did this right mind goes not gonna impact the output levels. From what reasons -- slowly down."

" It's. -- and I'm -- up. Yeah. Cool."

" have the right -- output. These are working at the the has stopped working on the pulls back -- can figure out what's working what's not working but we definitely have. The line level output or. The line level output working. So is much is fine as it might be watching troubleshoot -- punch you -- bathroom Brinker. There is when you right now while idea. At the very thing."

" And just like -- kids it starts working the way it's supposed to do after I told Roger I'm gonna have to re not everything. School figure. --"

" Okay."

" Yeah. -- no idea what's going on right now so that whenever wires loose so I'm gonna -- this crack open a third time and every out of those wires. And may be alternative use something a little -- and thirty --"

" And will let you know what happens a -- the system."

" I stopped doing little tiny. -- wire project. Doomed but. Don't say their data. --"

" All molesting before we go we're conducting a survey -- some additional information about our viewers we would love it if you take a couple minutes to give us your feedback. Please go to www. Revision3.com. Slash CS two that's SYS in the number two and take the survey thank you so much to help us out basically keep it sponsors come into the shows we during the shows can you.

" Only until."

" What's really awesome is they have the fix it guide series. Hold on a second always see if we need dial 911."

Having gotten my folks are red -- audio doesn't feel other models are worth modified. They figure that acts in other iPods aren't worth it it's a 250 dollar hack if you ever want audio do it RC 250 dollar professional modification. If you ever going on -- doing and it's well worth it if you have excellent source material lossless audio files and you run with an external amplifier. And you don't put a crack open your iPods or soldering this is not for the faint of heart. Now if you want to get hands on the fine folks head -- out or have an amazing resource for getting your audio directly out from those acts. But by Johnny boy who started in monster thread called Apple DIY mod my take on the famous -- mod featuring three G four G five. And the -- one G these people have put together in amazing resource complete DIY instructions and they also want to point out that this is not the I'm not this is their own version of way to get the audio from those Wolfson Dax. How to somewhere you can lead to an amplifier. And it's really not for beginners -- yes it will most definitely violate your warranty when you're cracking the case and soldering things down. Say goodbye it's not that your warranty period I think twice about this and if you're not willing to screw up. And break your iPod do not do this -- let's talk about the tools are gonna its primary tool is a spider to plastic or metal object basically took the -- used to pry open the case. You're gonna need a pair quality 47 -- capacitor Unita Saturn are with a small tip -- need to be adjustable then do a very low wattage reluctant fifteen. -- soldering iron. -- a light to change. A filtered Jewelers screw driver very steady hands and doppler dock connector you -- mod the willingness to break your iPod. Let's go over sort of 32 version."

" How this goes together we're gonna crack open your iPod. We're gonna get to the tax we're gonna -- a little tiny wires to a source from attack we gotta give the signal care on -- as little tiny wires away out like your headphone Jack or your dock connector. And yeah we've got to figure out where going to put this caps in the lines most likely in a doctorate dock connector outside your iPod put it all back together. And remember this requires an amplifier between the iPod in your headphones or you can use it to power. You know your amplifier in your home stereo. Remember if you're not ready for this watch than video don't start this project because this is pretty hardcore. Let's start out -- opening an iPod whether it's something like this little tiny iPod."

" Now which is this. And this. It and this or something like therapy and is busted up I think this is a second or third generation iPod they can third generation. They're pretty much a couple of things that are standard. They'll have a plastic topic contains the control mechanism or scroll wheel and the screen. Andy stainless steel back which is both solution and you probably hurts like -- I turn it towards the camera. That in between these two is a joint which is basically what you're looking for so -- tiny brightly visible line in between the stainless steel and the plastic. Okay we -- you -- basically we got this budget we made you got this budget box might fix it wherever it came from -- crack the iPod this is always terrifying moment right so you're looking for the layer between plastic and steel yet this budget that -- Angeles reports you mean. Gary Payton. Actually actually an -- doesn't -- if you don't get America one library TV. It's he discovered in the fridge in our offices. Apple got me back and upset if you want to approve what's your really not scared trying to think you're gonna bring the founder of the."

" Yes I'm going to bring the thunderbird -- one thing about this it's ultimately -- I mean I'm a little. When your little home in resolutely Apple now what actually little that gum -- little Apple juice box need."

" I've seen them around behind my time to understand that basically a chemical engineer originally came in here is basically Apple just concentrate. Instilled if you haven't seen it you should really watch your your getting into when it was someone's court yeah digital personally bucket the bucket makes it walk -- over here and I'm gonna get a few things that brought -- okay. Thanks -- you know you gotta spit right yeah I mean credit to spit on -- community it."

" And applicable -- you can check."

" They're normally you you drink lines of the civil and usual for you didn't. You know born in Russia. Simon grew up -- my -- pounding out a bucket of -- one of the only people didn't like immediately -- is essentially a little lighter than ever clear it's like 18070. Proof."

" Problem -- I've completely become -- magic and yeah. I'll blow everything out you know dot com. It's it's a lot cleaner than I expected. You know given Netflix such you know national did you guys are pros and its thing it's certainly believe he. Yes I mean you know it's got some nice round this on the back end of the Apple little Greg -- kind of feel going subtle and I liked the cleanliness of it. It's if it lets us practically pure alcohol and input it's clear I mean you don't have ever cleared we went a catalogue from botnets and and then rubbing. Koppel -- and it's got a little bit more complex and look at that -- kids com. It's. You know I'm wondering you know actually the result kind of like -- I'm imagining you know getting a nice little package -- beautiful logo on it maybe don't have -- And you can over the world system the Apple Jack and geeks everywhere I mean you know from grey -- we'll just take over -- like Ohio."

" But the thought about Kristall anymore -- Apple Jack. Give me a -- and while leveraging the argument June 23. -- So let that ultimately we should put that -- is all about bringing wind to the people like fruit fruit uptight -- nobody can -- Gary. Not your voice you're gonna let's get back to cracking open the iPod to me to get -- good -- that. Let's take a moment to thank one of our sponsors the united states air force. --"

" It's."

" Hey you know what we actually see how we made our sponsors when we do this one -- hide from theory into. With the back of the workshop we'll see -- we made this budgets crack this open and get this mod finished. All right -- back to the workshop again. And we're talking bass Rogers right what's this Roger roll okay telecommunications tool plastic keys for like moving wires around your -- in a closet our case basically. -- Anfield this page look at it right now I fix it dot com Donald they have an incredible source of giants for opening up iphones and iPods. And no one."

" We call those things Mac books and science. They sell lots and lots of tools primarily plastic the spider the heavy smoker and an analyst Roger. So you can purchase a sponge like this are available all sorts of us sites on the web for like 2345 bucks. We went with a little DIY action we actually have the fabulous. Six piece many chisel set we've found and the quality on this is atrocious. This is basically bad Indian steel by. It was a perfect tool to start out with -- give -- a nice kids to play with and we did a little bit of customizing. With our friends in the Emery paper yourself what do we do busily sharpening ads on that the tools started out with a pretty. Ms. double -- ground little bit on the wheels."

" The -- take up a little bit at a time. Can -- events."

" Glacier -- deliver rolling on the top of that we're gonna reduce the rest that with a little bit. Emery paper. So. So -- paper here that really matter I think or use and what's this like 800 -- we have some two point humor here cute when he's gonna basically take more steal off faster. And we want to -- is mixer. Get a nice clean reasonably sharp edge. And we're taking it extra that metal off of this and so plastics Rogers. If you want T actually make 18 popular item for making plastics -- would be in nylon. Chop stick or an old toothbrush. Any advantage of the plastics pledges the reason why they come in most battery replacement kits and stuff. Is because they're not gonna -- the plastic. On your iPhone. So move we got that toothbrush head cut off there and he we're gonna take our friends at the Emery paper. Basically want to nice stiff edge on that -- he had done that. Pretty in. And another something the steel ones are less likely to you more your iPod. Or the ST -- plastic spiders are less likely tomorrow your iPod. The steel ones are -- a lot easier to get."

" Under that edge -- we're doing here is your crack in. Basically -- split and they use this budget just put the space between the stainless steel back in the plastic front and then that you are waging an open again. So until this space there. Want to -- care you don't want to basically like -- can on this but what you do want to do is get he. -- Trashing Emery paper and away and then. You know we get these little senator. Julie picked up for five bucks isn't that cheap pair of about tweezers we split in half. This has a nice flat spatula and like that that's essentially that's a -- budget they -- is essentially a dentist's. When they called it not -- any. Specialist. And you know work that into the edge. Then basically want to like not -- thing and once you've got it in there. You basically go around and released the plastic connectors there's this plastic clips. And mostly when this pops open in the second. You'll see that -- and there is a series of metal clips on the inside this iPod back. That the plastic see these plastic clips here it is just happened place and that. Now if you -- the case little bit when you pry open which is really no room do not panic buying a sort of hard edged object put this piece of plywood here in just her role that edged back towards blacks and you see some kind of straight edge for example -- some rod here. To make sure that edge. Basically you know if you get any kind of -- here is -- smooth back down that we have a nice clean -- this is a pretty old pretty. Abuse iPod but the -- is still looking pretty. Not damaged."

" From our crime. Although it is a little stump fields so -- knows what -- in his pockets of this. Not only do they sell replacement parts for your iPod or iPhone or even your MacBook and MacBook probably have these very very excellent I fix it dot com slash guide and -- hear they're gone for Macs iphones and iPods or click on iPods. And look at that so the first generation iPod original the second generation third generation and at this point I think we count me. Third generation. Don't leads the other have well yes and what it'll do is basically telling you. How to open it up it's the component want to repair or replace in -- case what we're actually looking for is essentially the logic board -- access the larger ports that we can solder. Things do it. How to we know this because of that amazing Apple DIY mind thread. And if you go to that gigantic first page and that's I had five. Dot org webpage it has a huge table of contents that lists all of the models they have information on and you basically schooled now. Until you find your model so. You -- on second undefined network. Alright so basically issued here we cracked open not -- it is speaks clearing -- dead third generation iPod and which okay it was a fabulous experience and one of these you notice something is lots and lots of tiny preachers would quote screwdrivers for security drivers in there. Began. This couple -- down here and restore point that's a pretty much going to have to take all those apart. And notice especially the earlier ones they had pretty good size connectors here. Joining everything together the yeah. The jacks on there. What's it look at the product we're actually -- obviously this is already opened the kids in a fit of pique I decided the ceiling actually -- this thing together. Now look at the screen right now we're gonna they had -- that work. The thread on this one. What you're looking down is the top of being and no one G that's a pretty. Excellent example what you might find in that thread that lets you know where you can tap the audio out from that Wolfson microelectronics. -- And you know those little tiny whatever those things are disease on them look huge right well. -- You're closer to those in real life. The united how small those are that's thirty gage -- attached to the us. So let's just say the bigger the iPod generally speaking -- less. Painful lead -- reestablish going to be so I mean you're basically talking abouts. Some horrible connectors so this is that this is to of that connector on that third generation iPod right there. And the equivalent connector on this one is something old. Like. This and they know he'd seen that little ribbon connector next few my index finger. And what's really great you have to disassembled -- Underneath based -- this is over -- so. You're gonna have to do a whole lot of horrible stuff the -- fix it dot com guides are excellent for telling you how this looks like if you just template but if you're not comfortable moving. Little tiny wire little tiny switches is -- to release these ribbon cables. You've got to reach."

" Underneath that cover. And the flip. And looking even see that little black leader right there. That legal rights yeah plastic spiders are really afraid of damaging. You basically slide. Your -- and in this side and then when this is flipped down. It lock down that. Hopelessly obsessed with nonbelievers said puppy that are. Even look at that they're gonna and that's pretty much the action on this little tiny ribbon cables so maybe starting with the nano was not -- brightest idea. So. You can see be little tiny bits of sun that are willing to stand here spark fun. Dot com actually has -- pretty excellent guide."

" Q soldering service -- components and a lot of what they have had caught on there is kind of a neat go forward attitudes are they love. Yeah every this off the website because it's just that fabulous. Tools you absolutely must have a fifty dollar more soldering -- soldering -- and solder and that is always easier to work with soldering Wiki -- this reports also called these soldering -- what they basically use this is is to jump opinions if you've gotten too much solder connecting bunch of little tiny pins. And it of the top of that spark from web page. That's a typical connector there looking at a fifty pin connector for an -- that is made probably something it makes the thirty pin dock connector. Look pretty reasonable by comparison. So you'll -- be -- this earlier son. Fairly. Narrow -- are like gay solders to tailor these two pieces tolerate here. So this is like points or five inches in diameter is his point 32."

" The bigger the solder is more when this is gonna be to work with on these little tiny parts so. Pony -- spend the money even for lighter engaged and then the one I'm holding up here. This don't even bother trying you're gonna have a nightmare of a time."

" So the good idea exactly how small and 38 -- is and actually to talk a bit more about what her -- and it's more -- is to. There are big fans of using hot air we were working if you're working with service not components and hey it's a great read bullets that -- This shadows. But to give you basic idea unity is you don't make mistakes you can pretty much hotter with a --"

" Herndon and some -- but the idea exactly how small thirty gauges. The wire holding up here. Is a point four -- wireless to the wire found inside of a single wire inside of your ethernet cable. And right next to it is the thirty gage wire and maybe even come close to see -- those are secret yeah. And when you start soldering these things you start thinking about not drinking caffeine and moving far away from the part of the house it's migrated every time -- the Oscars."

" Yeah it's. Heart before we move on we have to think one of our sponsors these people a -- with a week after week isn't go to any dot com and we got to go to special deal for. Now you make an impact on line was a favorite do with -- dot com dot com names as -- a dollar and 99 cents world class -- my wife uses it for all website. Fast and easy website builders and quite a bit more. If you keep your personal information hidden from spammers hackers and -- permit -- stocking you since grad school. Private domain registration from go to -- dot com is gonna protect your privacy by keeping your address your phone number and more and who is database plus. Here's the deal theater includes students SYS two when you check out you're gonna -- an additional five bucks off in order thirty dollars or more -- restrictions that apply to -- the details on the website. Do us a favor here assistant teacher he's the Internet and go to any dot com and use actually asked to SYS -- this too when you check out."

" And support us by supporting them."

" So this is 38 wire wrapped wire it's available at your local RadioShack pretty cheap and we pick a couple -- that the -- and so. Just for fun and you prove that I am as least as dumb as -- look. One ID solder one of these insiders back down. And chances are that'll never actually be able Saturn back on again oh and I'll hold these actually just like fifteen Yorker Klein tools wire cutters. Or wire strippers that they sell it home -- possibly of those places like that. And they are spectacularly. Good for stripping smaller wire they basically have. Guides for solid stranded wire again thirty gig solid thirteen stranded actually. It makes it. -- daily ease of use. So -- you'll be -- A lot of it has tips already got my opinion. Basically spent a lot of time with every paper and locks and managed to revive what was left of carp beat up soldering iron -- last week. And lets you pick -- completely insane we actually do it if fairly good reason for on soldering iron piece out of one of these wires which is that. -- opening red wire on the right channel now which is. And that number 53 -- computer easy you can."

" Before the ones are specified for this every you know and that's -- and that is the amount why are actually worked with initially -- that down there."

" So if you think you've got a little this -- we don't we're gonna pretend you're from moment to think it'll over the solder jumping between those -- What you do is take your salary when it."

" And literally and I like to thank the fine folks its work fine for this tip this that is laid down there. And heated up with the side of your soldering iron and good gently on that -- likely pick up. And remove it before -- actually pick up the extra bits of -- down there."

" I hope would have been completely scorched the board but we're gonna take. In a -- Aaron there. It's. A -- ten heck yeah and second order has over thirty gage wire. And I gotta say this is horrendous stuff to work with because it's just so fine. We're gonna basically a -- this until we see it's not king -- news obviously. And schooling this earlier. -- And recycle that it's just nice chunk of wire. So is good to have more -- you can be released Saturday this done and be like -- no. Or as the but we'll Catholics say it only knows we're gonna take a little bit of little tiny bit probably even less than that true than than all. You see the tiniest bit. Clear wire on the and I don't -- orthodox but I -- a lot easier to work with. -- that was ten so. It's pull this masks back together. Make sure the have to check at this picture we haven't managed to solder -- that but I found it was little easier to have the wire pretends. He then up. Animal -- that could retain that. Okay here's the moment of truth or my final opportunity to completely screw this board once again. So remember we're going for pin he 53. With a little tiny had who simply has no side are right there. It's. If you go for the highly elicit a little bit of -- on the end of your soldering iron method. I'm pretty sure those of you who do this professionally or wincing right now but it's been working for me so. Actually gonna travel in a little bit more wire off the end of that. So we will get a wired there. Consumers to work when it. I really decided that or completely screwed up."

" Now we've got our little thirty gauge wires down on here we've checked. I'm pretty sure I haven't jumped to between the two tiny little circus not connectors -- happens. I'm everything's critical aspect and I think we're gonna do is actually end up. Connecting aren't wires for the right and left channel and of course when you ground and virtue you need dock connector here right. Sounds good want it though before we button and back up or when things and making it more permanent which means unfortunately that little tiny ribbon connector. And that unbelievably tiny ribbon connector need to be put into these two little ribbon connector -- yeah. Them every uber means what to call us. Basically I -- reassert those in England there. Lots. And that's not going to be approximately -- we can make it happen without. Permanently damage in anything on the right. Basically this is declined point -- which were horrible here. Did operate with the yeah. It out of power so. -- openness that actually had to do it can't be positive. And alert to her. Just refer to our needs only -- loose wires if we can give me. Analog outputs be created to work record button thing I'll take this out of these."

" Yeah it's."

" Went through Google oscars are definitely over this project. --"

" You know it's time take. A message from one of responses into the people who help us bring the show it to you today. Microsoft unified communications. They you can transition -- with a software solution and still get all the benefits of unified communications without having to rip and replace any hardware you don't you PBX. Now not everybody company knows about this technology in some IT guys are gonna extreme lengths to protect their hardware check out this video from Microsoft. And see just how far one man band is one you're gonna break his speedy action being -- replace. You've heard people protesting outside corporations find out what happens when a protest goes into wars."

" It is yeah."

" powered up it's playing we have put back together yet but it's not dead. Good science and and remarking about those little or not and I saw this evening it audio out of our cool guy. Line now from need to act which is. Played without first checking yes so. There right now in my network cable where you tell thing counts so it's good to grab -- yeah. Regular old stereo headphone cable. Hand. You guessed it -- is right what is left. That's little -- out of the music and the the common market to them that."

" We did this right mind goes not gonna impact the output levels. From what reasons -- slowly down."

" It's. -- and I'm -- up. Yeah. Cool."

" have the right -- output. These are working at the the has stopped working on the pulls back -- can figure out what's working what's not working but we definitely have. The line level output or. The line level output working. So is much is fine as it might be watching troubleshoot -- punch you -- bathroom Brinker. There is when you right now while idea. At the very thing."

" And just like -- kids it starts working the way it's supposed to do after I told Roger I'm gonna have to re not everything. School figure. --"

" Okay."

" Yeah. -- no idea what's going on right now so that whenever wires loose so I'm gonna -- this crack open a third time and every out of those wires. And may be alternative use something a little -- and thirty --"

" And will let you know what happens a -- the system."

" I stopped doing little tiny. -- wire project. Doomed but. Don't say their data. --"
