The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G! - Page 19

Wow, a lot of great stuff happening in the world of the diyMod!

I'll try to address everyone's issues one at a time.

CAvanessia:

It's good to see you got it working. I know the surprise you get when you hear the performer's breath. I listened to a violin concerto with KSC75s plugged straight into the DAC and you could hear him puffing and heaving. It was startling at first.

If you could take pictures of the dock pins, that would really help us figure out if a nano lineout is possible or how hard it would be to pull it off. If I hadn't been so lazy and uninventive the first time around with my diyMod, I could have actually routed the signal to the dock and avoid the whole rocket pack fad I seem to have started. It worked with the 4G and 5G, it might work for the nano!

Also, what kind of caps were you thinking of using once you got tired of the RatShacks?

vvs_75:

What film caps did you decide on for your mod? I'm really missing my iPod nano at this moment, but I should be getting another 4G click wheel soon. Please share with the rest of us your experiences and, most importantly, your photos

The 0.1uf, 0.47uf at 50V caps have the right voltage rating but are physically larger than the 6.3V set. The DC offset I measured was 1.5V, so 6.3V is more than appropriate for our application here. As for capacitance rating, I don't think that matters much besides the lower corner frequency, but as we've seen already, it won't make that big a difference between 22uF and 47uF paired with most amps.

iQEM:

How's your diyMod nano coming along? I haven't touched my Black Gates yet because I don't want to mess up this final, so I'm very anxious to open up my partsconneXion box. My other iPod dock connectors haven't arrived from Ridax yet, but I still have plenty of other things to work on over this Christmas break. I'll post pictures of how I did the diyMod dock, if you want

Austin 3:16:

Which iPod do you have? If you're willing to pay the price for parts and shipping I could pull off the mod for you. If I made any money, I'd have to become a Member of the Trade, something I'm not sure I'll do. We'll see. If you have any questions and are willing to take a $300 hit for a ~$300 savings, we're here for you

ruZZ.il:

As you probably already know, there are few hard and fast rules in the DIY realm, so you can try it that way if you like. But before you do that, consider that you'll be sure to let everyone know that your iPod is special and that they shouldn't just stick whatever docks they want wherever they want. I've found that even with my limited soldering experience and skill, I could still desolder the inductors lying just before the 4G's and 5G's dock audio pins. I'm sure you could do it as well. Nevertheless, we haven't had a successful internal diyMod nano 1G pulled off yet (that I know of), so I couldn't speak for you in that regard. I double checked and this website says that pin 24 is used for Firewire. I'm sure you meant pin 7 and 14, which are both not listed and, I assume, are unused. You could do it that way, but I wonder if Apple would put solder pads on the board for pins they weren't going to use anyway. You could just bite the bullet and desolder the inductors for pins 3 and 4, and then your nano would be compatible with ALO docks around world (think comparisons at meets). I prefer the latter way, but it's a free world, isn't it? You're free to do what you think is best.

A picture tells a thousand words. More photos will be invaluable to the frightened and uncertain DIYer, so that would be awesome if you could help us out with that.]

Keep up the great work, team. I'm excited to see so many of us being so adventurous with our precious players. Perhaps I will set up a dedicated web site to support this mod. That original post is getting mighty long.

Here are the wires from the DAC. [The left one is left, the right one is right. Looking at it the proper way would put the top pad as the right channel, and the bottom one the left. I hope that doesn't confuse you.]



I can provide pictures of the dock tonight. You can fiddle around inside and see for yourself, but there shouldn't be a problem with me uploading some tonight.

I did what I could. The pads are right next to each other this time as opposed to in the 5G. L2 and L3 are the intended destinations. It's probably not as helpful if the wiring isn't colour coded.



The left channel of the DAC goes to L3, and the right channel goes to L2. There's another wire shorting L4 since I accidentally removed it.

>so you're telling me to get the 6.3v blackgates right?

Yes.

>Making an order now! How expensive is partsconnexion shipping?

Mine was about $15 and it arrived in 3 business days. Order quickly, they close on the 21st and don't ship anything until the new year!

>Also what hook up wire to get? Radio shack?
Anything small. 30AWG, 28AWG, anything you fancy.

>What soldering iron are you guys using?

Weller WLC100, but I don't know if that matters. I probably should pick up some new tips, something finer than the stock. Hakko 936 sounds good though.
