The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G! - Page 29

post #421 of 3000
Yeah I know there are different factors that are involved... but I'm just kinda disappointed at the minimal difference that I'm hearing, instead of what everyone seems to be hearing. I'm a little worried because my friend and I arranged for a iMod vs DIYMod "showdown" this week lol. But well... I will probably find more discerning ears to try it out. Oh and I realized I forgot to thank you for having this thread up, really appreciated the effort you put in joneeboi!

Glad I could help

Like I said earlier, it could be the Bose effect that the iMod owners are hearing. Some of the claims they make are so wild that you wonder how a $5 chip could make such a difference. I, too, found it to sound really good, but I haven't ever heard a high-end external DAC. I tried to get an Alien DAC to work on my laptop but Vista+foobar2000 was working weird for me. It's good that you can cram so much music into your external amplifiers, but beyond that I wonder how good it can really get. Nobody has explored the digital out diyMod yet, so once that gets going, everything will get insane. Remember that the Wolf[s]on CODECs use I2S signals to give us our musics, so a digital out iPod isn't so insane. Tapping the right pads might be a bit more difficult, however.

Please share with us the results of your comparo, KoKo. I'm sure it'll be the first of many once this diyMod thing really gets going.

do you ppl have any idea WHY my clickwheel didn't work properly ? i still can press menu button but the other button no response...

iQEM: check the ribbon, make sure its plugged in propoerly.
KoKo: what headphone/amp are you using? if you're setup is'nt revealing enough, you may not be able to pick up the differences.. we're talking about a quieter background, better detail, more controlled bass, better separation (kind of like a wider sound stage).. these differences are already heard through the normal line out dock compared to the headphone out.. the diymod just does it a bit better.. none of these would be observable with say, the stock ipod headphones.. nor anything in their range.

Okay my set up is actually pretty average. I'm using my above average desktop speakers which has an amp. Both jacks are plugged into that amp which has AUX channel and the Main channel so it allows me to switch channels easily. For the "showdown" though, I will be going to an audio shop to do it, and I'm most probably gonna use the studio monitoring speakers they have setup there. That might say more bout the mod. I know my setup isn't really good, but because of all the reviews maybe my expectations were abit too high, that's why I was disappointed at the almost undetectable difference it made when I hooked it up. Perhaps it's my room too, it's not very optimized for sound. So yeah, once I do the comparison, I will tell you guys bout the results for sure. It'll be iMod vs DIYMod vs iPod hopefully. Good luck to me/us!

iQEM:

Check the ribbon for any kind of cuts or damage. Also, if there isn't enough pressure on the cable, the click wheel won't respond. Make sure you flip down the tab and that the ribbon is secure. I actually snapped the tab on my nano's click wheel slot before I gave it away, but I resolved the problem by jamming a folded piece of paper in there. Isn't that a new click wheel as well? If it is, I'd say the problem lies with the connection, not the ribbon cable, unless you broke it

KoKoKrunch:

From what I've seen, expectation is one of the great deciders in audio and in life. What the heck do I mean by that? When your expectations are low, it's easier to be surprised. When your expectations are too high, it's easier to be disappointed. When someone sees the price tag on a Grado RA-1, they're expecting the sound to match that of similarly priced equipment. But when they finally hear it, it becomes a whole new ball game. "I prefer the Melos SHA-1s selling for the same price in the FS forums that nobody seems to want to buy." On the other hand, that's why head-fi is also in love with the Koss KSC75 and KSC35. You don't expect much from such a cheap headphone, but it delivers. I let my brother listen to it when I first got one, and he just laid on the stairs listening for something like half an hour, mesmerized by the sound, unaware of its price or its legacy. In that vein, try to keep an open mind when you're at the showdown. Give each setup the same chance you gave the last, and that way you'll get a better perspective on which is better.

Oh yeah, take pictures and send us all a postcard

Talking about damaged ribbons, mine got a little screwed up (uhoh..), but I'm in the process of ordering a new clickwheel for like 5$ from ebay I'm also ordering a bunch of parts to repair friends broken pods.. cracked screens, etc.. got me into it now :P

I have an update to my diyMod 4G click wheel. I recently got another one from my friend. His was broken, which I quickly and cleanly fixed. Turns out the hard drive from my old diyMod was perfectly fine, it's just that I messed up the logic board. As you can see in the photo, I accidentally removed an inductor beside the line out inductors, which probably was the one that finally crippled my diyMod. Alas, it's good to have another iPod, one that doesn't have holes all over the back. This is good news. I will be diyModding it now.

Notice the missing inductor at L4 which was replaced by a short. That wire did no good.

Why hasn't vvs posted his impressions?!? I want to know how good those Sonicaps are

Well, after an hour of work, I finally pulled off the diyMod 4G internal BGs configuration. Those tiny inductors are hard to work with, and it's easy to tear the pad right off the board if you're not careful. Also, you have to be careful how you orient the BGs' leads once they find themselves south of the hard drive, cause it is very little clearance here, not to mention there's something screwed to the back casing of the iPod that introduces more obstruction in this area. I think I pulled it off okay so that it won't ever short against the dock's outer casing. I'm burning in my MAX's BGs, and who knows if I'll keep those once I try out the Silmic IIs and Muse ESs, so no sonic impressions from me. We'll have to rely on KoKo for that.

powertoold:

Maybe if you PM him, he'll post it. He's been pretty good with responding to PMs so far.

WOW! I used to be a frequent visitor to hackaday. Even before this thread existed, I searched hackaday for an iMod-type hack but did not find anything.

Congrats joneeboi!

I'm still waiting for my new nano battery and parts... the wait is agonizing! I would also like impressions on the soniccaps.

Rely on me? For what??? The comparison???

So jonee you did it the way my dad and I did? Heh that's cool. Oh, the thing screwed to the back you are talking about is the dock connector sleeve right? For me, we grind-ed(i know the past tense of grind is ground, but just to avoid confusion lol) the screws on the dock jack sleeve flatter, so that it doesn't push too hard against the cover.

Oh and jonee, if I want to line it to the iPod headphone jack (I might want to switch to more Hi-Q wires in the near future, but I don't have a Hi-Q dock), where do I solder the L and R ends to? Any idea?
post #435 of 3000
Hiz pls enlighten me

much interested in the ipod mod for the 5th gen but if you could help me out as
is the wiring diagram from ur post as to remove the 4cap as show on you post and soldering the 2 wires the the point as shown in which the signal path will direct to the dock which is the black gates cap to use on the dock that Red wine audio uses?
As imod from Red wind audio becos it cost hell of a lot?
and one last question which is the prefer wire for the solder? should i use silver wires or copper? or silver solder?
