I'm sorry my picture was confusing! What was confusing about it?

I think I understand why you're confused. In the current picture, I am NOT doing the dock-connector method. That's why I'm grounding at that spot. If you're doing the dock-connector method, you can just ground on pin 2 like wgr73 mentioned, not at where I grounded since that would be redundant.

My "temporary" setup just has 2 caps soldered to the 2 signal wires which goes to a 3.5mm plug. The ground from the plug is the RED wire in my pic. The spot in the pic is the headphone ground (from the nano's built-in headphone jack).

Hope that clears something up.

What amp are you planning on using your diyMod nano with, CAvanessia?
I'm currently using a Meier Porta Corda. I wish Xin had better delivery times. With my current setup, I don't notice a HUGE difference in sound quality. I hope it's because of the caps or the bitrate of my music.

Be glad that finals are over! Over at my Uni, we only have one week for finals. =P I'm anxiously waiting for my grades.

Hey, I wasnt saying your pic was confusing....just this whole modding deal. There are so many ways one could do the mod that it gets confusing! Anyone confused?

*raises hand*

Oops - I think i mis-quoted. I was going to quote iQEM.

The last bit of the puzzle is to find out which dock pins are the right ones to use on the nano. I think my multimeter probes are too fat. I'm going to run over to Radioshack to get some better ones before I test again.

wgr73, if you would be so generous as to attempt the...ZuMod, we may actually find a way to not only have a great-sounding player, but also a way to have a true line out for the Zune! As I'm sure most Zune players are disappointed with the same sonics but crippled dock line out, a ZuMod is exactly what "The Social" is in need of. I could try and steal my friend's player, but I'm not sure how that would go down. Zunes are going so cheap everywhere that maybe I ought to pick one up. I just threw some Black Gates into my Millett Hybrid MAX and I just picked up my Digikey package from Purolator today ($8 shipping, 3 business day waiting time, no pickup charge? Am I dreaming?), so I still have some things to recover from financially. If you could spearhead this, I would greatly appreciate it. Good luck on the mod! I really need to get a move on this website then, don't I?

iQEM:

If you want to use the dock connector, you don't need to solder anything to ground inside the iPod. All that's required is a pair of wires from the DAC to the dock. The grounding happens inside your LOD, so you don't need to worry about grounding.

Pins 1 and 2 are the same, so you can use either one. I would go with pin 1 because it's farther away from pins 3 and 4, your audio pins. This way it's just that extra bit safer.

Hey guys just a quick question. Do I have to pluck out the capacitors which I'm soldering to?

Thak you all for this! I'm going to make my own auricap fidelity dock for my 5g ipod. But I'm little confused about connecting caps with pins in the dock and RCA out's. I think I should connent one end of the auricap to pin #3 and another end of that same cap to the right RCA out pin.The same with another cap and pin#4 just this time I'm connecting another end to the left RCA out.Now what about ground? Should I solder two wires to the pin#2 in the dock and connect them with ground pins on both left and right RCA out's?Also what about all the other pins in the dock, should I just left them untouched. I would really appreciate the help. Thanks

then i'm gonna do it right now, do i need a multitester to doing this ? how do i know which part of caps that i should solder to ? there are two feet out from caps (i use 22uF BG 6,3v), the other one are taller than the rest...which one are (+) and which are (-) ?! (sorry for my bad english, cos english are not my native language anyway...) thx before...

iQEM, the capacitor you are using is non-polar. No + or -. Work either way. (I 99% suppose)

What if I someone has polarized caps? Because that might be my problem.

The Positive (long leg) would go to the source (ipod), whilst the other straight to the output.
iQEM: The BG NXs are non-polar just as KoKo mentioned, so it really wouldn't matter which way you put it (even though there is a long/short leg.. it doesn't matter..).

26 Line In - Right
