holy crap. i opened my nano today and i'm speechless. the parts are UNBELIEVABLY small. I don't think I have the skill to solder the pins to get a dock-connector working and the equipment. I think i might need to drill just to avoid that.

I might just run to radioshack nearby to get some 30 gauge wires and crappy capacitors just to see if I can do it before my other parts come =p

Soldering to the dock pins can be very intimidating. I smudged a lot of solder around on my 4G and 5G, but eventually I got it. You just need to take your time and settle your hands down as you work on your iPod. Make sure you secure the iPod while you're at it, cause you don't want to be working with a shaky board with such high stakes. Add a bit of solder to the tip of your gun, heat both ends of the inductors, and just keep alternating. Watch some of Tangent's tutorials on desoldering components.

Use flux too CAvanessia, that really helps with solder direction. Apply it to the component you want to solder, and it will "suck up" the solder!

thanks for the support everyone! the dock pins (on my 1g nano) aren't labeled the same as the pictures from this thread (from the classic ipods). all i see is C75L13 and other similar notations around the dock pins. No L2, L3, etc.

Also directly below those pins towards the actual dock, it is too tight for me to get my soldering tip to the joint. In dock picture on the front page of this thread, the "space" i'm talking about is exactly where the hand-drawn green line kinks. It's right below the inductors. I'm afraid that when I put my soldering iron close to them, it will touch the neighboring parts.

My camera can't even get any macro shots, so I can't show you guys what I'm talking about. Any advice is appreciated. I think I will try the direct method first.

The way I found which pads to solder to was by hooking up a line out cable to the dock and using the ohmmeter function of a multimeter. If you touch one lead to either the left or right channel and use the other lead to make educated guesses about the location of the pins on the logic board, you'll find the right pads faster You'll know when you find the right one when the ohmmeter gives you 0 ohms, meaning there's a short circuit, or direct signal path, between the two leads.

I haven't ventured into this territory, so you're going to have to pick up some of the slack, Christine.

Be careful with the use of flux on the board. If you put too much, things will get messy. I don't think electrically anything will go wrong, but there will be a sticky paste that remains until you decide you should have cleaned it in the first place and go back in to wash it out.

And so far, two of us have forgotten to ground the stereo jack coming straight from the chip. If you want to pigtail it, ground it.

Yeah, you're right. I actually have a DIY LOD around, so I should definitely do that.

For now, I think my 1g Nano diyMod is working! I soldered two wires to the C54/C54 spots and put cheapo Radioshack 10uf capacitors on them. I also used a cheap radioshack male 3.5mm plug. The ground cable is soldered to the headphone ground that I found using my multimeter.

From the pic you can see that I used extremely long wires, and the capacitors/wires are all over my table.

No real impressions yet as I've never heard the nano. Also, it only has the previous owner's songs. However, there was one song that I swear the singer was right next to me! I swear I heard her licking her lips or something. lol.

Use as soft wires as you can find. If you don't like my "bridge" method then secure wires with pads with a glue otherwise you will brake off the pads!

Also I got my nano today, so my version of the 1gen nano mod with films caps coming soon.

I just hope to see that with each generation our mods will improve toward more prof. level.

Since i'll be reservicing a nano, I might as well try this one on my own.

I'm looking on partsconnexion and don't get which caps to buy

There are 4 different blackgates

NX-Hi-Q 0.1uf, 0.47uf...both rated at 50v

or

Nx-Hi-Q 22uf or 47uf...both rated at 6.3v


also, what type of wire should I use to hook up the caps?

I have some 24gauge navship stranded SPC...would that work?

I'm so noob with this stuff....no one has figured out how to do an internal nano mod without the external case have they?

thanks

Try to find some 30AWG wires and Nx-Hi-Q 47uf.. 6.3v you need.

You can solder wires directly from the caps pads to the dock pins and you put Nx-Hi-Q 22uf.. 6.3v caps in to the dock to mini connector plug like ALO did.

"Nx-Hi-Q 22uf or 47uf...both rated at 6.3v" are the right one...
my teori (thx to all brilliant person like joneeboi, wgr73, ishtob & vvs_75) i can just route the wires like jERiCOh did HERE, then put the BG caps inside the dock connector line-out to mini...

aha, just i like what i've take from this thread...but what the uses of 30AWG wires for ? is it for wires from lineout dock to mini connector ?

As far as I understood he asked which wire to use for internal soldering between dac chip and dock connector.

Thanks vvs!

I'm getting a friends 5G today too! He let me have it (he said he doesn't use it!). So I want to mod that too! I'm not sure if yo guys want pics, if so I'll take some. And I'll probably route the wires like jericoh did....we'll see.
