Fabbed circuit boards!

Got my first run of fabbed circuit boards today; they look sick! I'll def be ordering more boards through OSHPark.com :)

updated code

Here's some updated code. This should fix the flickering of the SID text when switching to Aux mode. Also removed the 0x368 messages - Henrik informed me that they weren't needed. Not much else changed I don't think. This still includes the main CDC code as well as the extra code for 9-5's.

New board design

I decided to fix up the board design. I added a jumper underneath the 328P socket, but I added all the holes for the unused pins on all the DIP sockets, so no more cutting off pins! :)

REMEMBER : This view of the board is the BOTTOM, so all the components go on the other side, and that means you have to watch out for pin 1 on all the ICs! It's a little confusing, even for me. I just hold the board like it looks below and hold the IC in the air, as it were going to match the image, and then flip the two over, and it should have the proper orientation. It also helps a lot to watch for the pin 1 indicator; the indentation in the sockets.

The reason I designed the board like this is because it makes it easier for me to manufacture the boards. I mill them out, and of course the side you mill has to be "up", so this way I don't have to reverse the file when I export it out to the routing program.

Compatibility

I think this module is compatible with the following series:

1998 - 2002 9-3

1998 - 2003 9-3 convertible

1998 - 2005 9-5

Don't hold me to those for sure, especially the 9-5 series; I'm a 9-3 guy :)

For sale?

I'm curious to see how many people would be interested in buying one of these units for $100, shipping included, and you would get to customize your SID text (12 characters max)!

I would include the Radio Shack connector, CU3242MB case, and it would pretty much be ready to go, just need installed. It's not exactly plug-n-play though; obviously you would need to cut off your CD Changer connector & replace it with the radio shack connector. Also, the way I've been doing these is putting a RJ45 female on the audio in (from ipod/mp3/whatever) and ipod control lines (5 total wires), and then making another female RJ45 to 3.5mm (or an ipod breakout connector if you want ipod control). I would leave that end up to you. This would allow you to get any old ethernet/CAT5 cable laying around and route it under your trim panels from the trunk to the front of the car. Then you can decide how/where you want your input to be at.

A LOT of this "kit" would be custom, BY YOU. I would only supply the Aux-In unit.

What do you think??

Saab 9-5 working!

I installed a 2nd unit into my friend's dad's 9-5 today. Had to adjust the code slightly, but not much. Just the CD changer code. Apparently the 9-5 sends a code to the CD changer, and the CD changer has to respond with a code. Not like how the 9-3 works. But it was a simple software change and we got it working! Code is below. I'm sure it could all be contained into one program, but I haven't tested it so I don't wanna post it and it not work.

The 9-5 apparently sends a 6A1 command to the CD changer, and the CD changer has to respond with a 6A2 command that says "I'm here, I'm ok!". In the code below, this command is the "ninefivecmd" array of hex codes :) I found this information Here

Also, I wanted to add that I bought these connectors at Radio Shack for $3/ea and they worked great! 9-Position Male Polarized Connector, PN 274-229 and 9-Position Female Polarized Connector PN 274-239 You have to crimp the pins with a special tool; in my case it's called a Letherman SuperTool 300 ;)
