interested in hearing from the people that invest in this mod to tell us their experiences. all looks very well thought out. congrats!

I assume there is a design reason for the ordering of the wire numbers but it did make my OCD tingle a bit how the order jumps around instead of for example RR +, RR -, LR +, LR -, etc.

That said it was still easy enough to follow along for a novice like myself.

Haha, I hear you. And yes, there is a design reason and it's an unavoidable one:

So, the pinout of the device is dependent of the pinout of the car itself. One of the design goals I set early on was to make the device as small as possible with the lowest possible insertion loss (ie parasitic resistance). In order to do this, one needs to be efficient with your two-dimensional space on your printed circuit boards aka PCBs.

Since the input pins are fixed by the car, the trace routing to the output pins is necessarily constrained, unless you want to make a hot spaghetti mess of traces on your PCB which is bad engineering practice for many reasons.

Further, the pinout order become pretty irrelevant when you start talking about pigtails - when you look at the end of the wiring harness that goes to your DSP, you're not really going to be able to tell the difference between two different pinouts at the connector side.

Here's a visual of what I'm talking about. This is the daughterboard side of the device (none of the logic is happening here, just I/O). The speaker traces are the ones going vertically between the two leftmost connectors. The top left connector is the OE Honda connector and the bottom left connector is the output connector to your DSP. If you wanted to "prettify" the pinout of the bottom connector, the trace routing between the two would have to be a den of snakes.

Hopefully this explains the design choice, and limitation of the pinout!

And this is Honda's own pinout diagram for the input connector:

You can see Honda doesn't follow a visually consistent sequence themselves. Pinout design decisions are primarily dictated by packaging efficiency needs, and to a lesser extent, crosstalk and EMI control.

Folks, I'd love some feedback on what questions you have and expect others to have if they are considering the PURE integrator. I started a skeleton FAQ, pasted below:

Folks, I'd love some feedback on what questions you have and expect others to have if they are considering the PURE integrator.

* "Can I Plug N Play music directly from a USB drive? What is the best way to integrate music directly via USB drive?"

THIS is the #1 most important thing I want to learn how to do. Play my awesome music that I OWN in my awesome car that I OWN! It should be a no brainer, but of course "They" make this damn near impossible to accomplish.
EDIT: We know exactly why "They" make this so difficult.
Ask Kl&us $chwab: "You will own nothing, and you will be happy."

Also,

* "What types of Digital Audio Players (DAP) are recommended for use with this PURE Integrator?"

And,

* "What are the recommended Audio Formats for my music files in order to get the best quality sound from my USB drive or Digital Audio Player (DAP) in my car?"


Personal note:
I want to buy a dedicated mid/high end DAP with SD Card or MicroSD Card slot for my music. I never have, and NEVER WILL pay for a subscription music service scam like SiriusXM or Spotify. (Stop harassing me, SiriusXM.)

Right now I have MP3s and .WAV files on a MicroSD Card that I play via an old Samsung Android phone. I removed the SIM card from the old phone and use it strictly as a BlueTooth audio player.
EDIT: Forgot to mention, that I installed and use the free Hiby music player app for Android in this old Samsung phone. It seems to work pretty well for a free app.

However, recently, the phone occassionally locks up while playing files, and I have to pause, rewind, and skip ahead to the next track, etc. in order to keep listening to my music files. I do not know whether the culprit is:

* The Phone,
* The MicroSD Card, or
* The File Formats, MP3 and .WAV.

Either way, that phone is pretty old, and not really a dedicated audio player anyway.

On a side note, I am looking into switching from Windows to Linux. While I really like .WAV files for their relatively good quality, I'm not sure that is a file type that will be usable via any audio or music programs in Linux. I'm totally clueless in this department. Just haven't done any research yet regarding Linux audio programs.

 

[ashmostro]

Awesome questions!

Will address them both here and on my site later today.

Parts are all in today so I am soldering and assembling!

Just want to say that this is an impressive project! Your attention to detail and education is cool to see.

 

[ashmostro]

Thanks for the kind words!

I can’t help you with the audio file stuff, but I can tell you that Linux is the best thing since the spork.
