Looks and works good, even with a white iPod…
(Click for more…)

Well the white iPod stands out a bit in the all grey and black center console, that doesn’t stop it from working.

Yes, it’s done. Completely done.

That is, the iPod adapter I’ve been working on for a good part of the last week and a half or so has finally been completed. Designed as a replacement for the Honda Music Link which gave me so much trouble (photos here (photo gallery retired)) it does exactly what I want and works exactly as designed. It firmly holds the iPod in place, plays audio through the factory Aux In, is within arm’s reach of the driver, and keeps the display in sight at all times.

As was proven with the iPod setup in my previous vehicle, such a setup works very well. I had originally intended to make such an adapter right after I originally accepted delivery of my 2006 Honda Civic EX (photo gallery retired), I was convinced to wait for a factory adapter, the Honda Music Link, by the promises made in this press release. Most people who read this journal know how that ended up going, although I guess the events surrounding it made it much easier for me to make the adapter. With one person providing me some nice technical detail about the pinout in 2006 Civics, people to bounce ideas off, and just with it regularly being on my mind, things seemed to work out pretty good.

That all said, here’s a few notable photos from both last night and today’s work:

· The base of the iPod holder bolted into the trim piece from the center console.
· The underside of the PCB, just before I closed up the box.
· All the parts in the interface box, just before I screwed it closed.
· Goop applied to the interface box and padding foam.
· Clamping down the interface box to the workbench to help the adhesive on the foam set.
· The finished kit, ready to be fit into the console and dash of the vehicle.
· The interface box strapped to a pipe inside the console.
· The holder and stand match the vehicle’s interior quite nicely.
· Larger view of the photo above, showing how the iPod fits amongst other parts in the console.

Of course, all the photos from this project are available here: iPod in 2006 Honda Civic (EX w/Navigation) » Second Version (Built-In) (photo gallery retired)

The only thing left to do is get my current white 40GB iPod Photo replaced under AppleCare (it has the problem detailed in these two H.264 videos: 1 – 2) and purchase a 30GB 5th Generation iPod Color in black. Then everything will match nicely… Oh, I’ll be selling the iPod, so you’ll likely see an ad here for it, if someone doesn’t pick it up first.

Now, to clean up my workbench and the table near by. Well, maybe I’ll do that tomorrow… Instead I’ll write another LJ post. Or something.

Yes, I know that’s not the most impressive photo, but that’s the completion of my work tonight. I ended up making a new and much better PCB with which to tie everything together, mounted the filter and resistor, installed the second grommet in the case, soldered on the previously made Aux In cable, added the power cable, hacked in a fuse for the power cable, and called it a night.

So, yeah. Now the only things left to do are tear into the dash again, finally assemble and bolt in the iPod holder, run the iPod dock cable through the base of the stuff pocket in the console (whoops, need to purchase another 7/16OD x 1/4ID grommet), add the ends to the power cable, plug both the power and aux in cables in, strap the project box to a support in the console, and close it all up. Then, provided things go the way I want, it should just work.

After that I’ll start looking into changing the firmware on the head unit to read IPOD instead of AUX, and I’ll probably start seriously looking more into the Honda Music Link Device. I’ve got a growing desire to document as much about it as I can. Pinouts, high res board photos, and if the board doesn’t have too many layers, I may even try to work up a schematic. Or maybe even read out the ROM. We’ll see…

UPDATE: Oh, I forgot to add this photo of the bottle of acid, namely ferric cloride in water. I had it sitting in a pyrex measuring cup for two days because I wasn’t sure what to do with it. It can’t come in contact with metal at all, so I was having a hard time finding a container for it. While I was at GFS unsuccessfully looking through their cleaning products for such a contain, it came to me that I should just use a 1L wide-mouth Aquafina bottle to hold it. So I did. It’s working out nicely. Now I can save the solution to use a few months from now.

Okay, I did decide to post a shot of the PCB tonight. That’s it, in the project box I chose for making this. It seems like it’ll work out pretty good, even though I likely could have gone with a smaller box. Ah well…

That there is the PCB I made, and this is the solder side of it right after I finished cleaning it up. The etching isn’t perfect, but it meters out solidly. So, hopefully it’ll work.

The components installed there are the 1MΩ resistor to make the iPod pause when the power stops and a salvaged choke (I hope I’m calling that the right thing) to hopefully eliminate any extra noise in the +12v coming from the car.

So, that’s about that… I’m likely going to the auto show tomorrow, so maybe I’ll get back to things on Thursday. We’ll see how that goes. :)

Oh, and all the photos from today can be found starting here and on in (photo gallery retired). Yes, there are lots of the PCB. It was the first I made, so I wanted to document it.

Finished custom Aux In connector. (Click for more…)

Well, a bit more progress was made on the iPod connection for my car. Today I soldered up the Aux In connector, potted it in epoxy for strength, shrink tubed it, soldered a 3.5mm (1/8″) connector on the other end for testing purposes, and tested it out. And guess what? It works just as designed.

The connector fits into the factory connector perfectly, tells the Navigation Unit (head unit) that there is something connected to Aux In, and accepts audio in phase on the proper channels.

Also, while cutting the black TuneDok stem to fit, it seems that I squeezed everything so hard that it caused oil to be squeezed out of the vinyl. Wow.

So, yeah. Both the spacer and heads of the bolts are painted, and I’m just waiting for the aluminum plates to dry so I can photograph them. I did get this really nifty photo of wet paint on one of the aluminum washers which I think could do nicely as a flyer photo or something. Well, provided the flyer was printed fairly nicely.

Now all I need to do is order the rest of the parts I need. These should include a cast aluminum project box, PCB etching kit, tin coating kit, and a few other odds and ends which I need to finish everything up. I’ll go order those now, I think.
