Well, I know what you mean by putting everything in hw, as much as possible, but that's just not how I see it...Originally Posted by RPM_VR4
We have a very powerfull platform (x86) already running, so why add microcontrollers everywhere?
On the interface, I agree, not on the EQ.-music + EQ
We definatly need a good music interface that allows people to get to anysong quickly WITHOUT looking at the screen. Using a remote control and text-to-speach voice feedback, I should be able to get to any Album/Artist/Genre and then Song within 20 clicks of the remote (worst case). As for EQ, that is the job of a good head-unit, not the CarPC.
It's very well doable to have a nice EQ, so why add cost and take up space with something you can't even link to what happens on the pc (phone needs another eq-setting then music, and music something else then DVD...)?
A head-unit should be useless in a complete solution, that's the base of my logic: a revolutionary replacement for several devices (laptop/pda/head-unit/dvd-player/phone+carkit/GPS-navigation/tv-tuner etc...). I know a lot of these combine some functions but I just want everything in one device, nothing more
For us geeks, it's nice to have everything on disk, but I want to sell my solution to people that have cd's and rent dvd's.-dvd + divx + EQ
Personally, I don't even have a CD-ROM drive in my CarPC, but I do understand why a lot of people still cling to removable media. DiVX/XVid support is definatly a must, but every front-end does that. Once again, no EQ.
All front-ends do it, but EQ lacks, true.
Well, I don't know of any serial cables providing handsfree, but I know some modules that I could include into my solution as an option and they're serial. Just a question of linking the microphone and sound output to the pc's line-in.-phone integration (bt AND serial)
Do any of the USB cables allow hands-free speaker phone, or is that only BlueTooth? I would really like this feature, but I am stuck with an incompatible SamSung USB cable because Sprint doesn't really have anything better. My cell bill is $60/mo for 2 phones with way more minuites than I use and unlimited internet access though, so I'm not switching carriers. Anyway, though you miss out on contact dialing, phone -to- head-unit hardware interfaces is an alternative (though definatly not as good if you are lucky enough to have a software compatible phone).
I'm not convinced. This is what I meant for the radio, and a prototype is working fine, as they use modules built for HU's: HU Quality AM/FM RDS/RBDS Radio with Features-radio (the USB-tuner project)
Useless (even SAT radio)! A good sounding system has to have a head-unit. 99.9% of the time I am listining to MP3s and the other .1% is music-videos/movies. Why would I ever want the radio? ...and if for some strange reason I did, I can just source the head-unit to FM (or SAT) instead of CarPC (AUX/CD-Changer).
Also, I don't believe I'll sell this alot as a replacement for a HU if it hasn't got radio. Marketing-wise AND just economically, as a company can leave out a radio-option when leasing/buying new cars.
The constant internet still proves to be a problem, and will for some time. For extra funtionality it's nice though (phonebook thing for ex.)-integrated navigation (preferably better than D3), for EUROPE
iG is awesome, but I'm in the US. Google-Maps / MSN Maps will be the future I believe (once they do a bit more dev and more poeple have constant internet in their cars)
I disagree again This is hacking. Nice for my own car, but not when you want to be able to sell various screen options. Also, when a Xenarc switches sources it acts ugly (text appearing, resolution displayed, screen jumping left/right when auto-adjusting)...-rearview-cam, switched on the serial port
This is a job for hardware. Attach the rear-view cam to the video input on the 7" LCD. Make a microcontroller program that sends IR to the LCD to switch to video source when in reverse, and to VGA source when not in reverse. The PC with an IR blaster (or talking to the microcontroller) could also control the LCD source (like maybe the LCD shows rear-view until the CarPC fully boots, and then the PC auto-sends IR to change to VGA).
Although I like the idea of the rearview until booted...
Carnetix is not good enough for what I require. The screen should only go on when the front-end is fully loaded, so you don't see POST/windows booting/windows loading, everytime with different resolutions and a jumping screen...so even if you hack post-logo and windows, you still see the screen auto-adjusting all the time.-supports 1 relay on the serial port to activate amp+screen(s) when booted/resumed to FULLY WORKING STATE and disactivate them BEFORE shutting down/hibernating
Dude, you just need a good startup/shutdown controller. My Carnetix will wait for 2 seconds after crank, start the PC, wait one more second, start the monitor/head-unit/amps. When the key is out, it kills the monitor/head-unit/amps one second later and begins PC shutdown 10 seconds later. Works great. You could program a microcontroller to work it anyway you need.
True.-all skinnable and menu-driven, so it is very touch-screen friendly
Yep. And don't forget remote friendly too.
Depends on what onboard soundcard you have, but I haven't seen one doing the job the audigy does. When you use a HU to tune, you're just covering up, but you'll never get the sound at 24bit/96khz. I hear the difference very well between my audigy and the onboard vinyl of the epia mII 12k!-still runs smooth when an audigy 2nx is added to the mix
Why? On-board sound plugged in to a head-units line-in sounds great. I wouldn't waste the money on a sound-card. With a good head-unit for tuning, you will never hear the differance. We really need the CarPC to appear to the head-unit as a CD-Changer so you can just use the head-unit controls/remote to navigate the frontend.
But this might be interesting for you and others keeping their HU (and that will be an OPTION in my commercial solution, but I don't like it to be necesarry t have a HU, that's all): Testers needed: VW, AUDI, BMW stock headunit USB adapter !
Well, the relay-cards that I meant are microcontrolled, with USB or serial link to the pc. A unified protocol is important.OPTIONAL:
-multi-zone (multi-sound+multi screen)
Relay's should be controled by a microcontroller that talks to the PC, not the PC directly. Someone should come up with a unified microcontroller board -to- frontend protocall. My SiLabs micro board will eventually emulate a Pioneer CD-Changer, send & recieve IR, and talk to my steering wheel controls, alarm, and On-Star mirror.
In my vision the total logging is not a must, as that's hard to build universally compatible with vehicles hardware-wise. It would be a very nice option though.Vehicle tracking is a must. Actually, full car activity logging is what I am looking for. If I give you a time/date, I want to know where I was, where I was coming from, where I was going to, what speed I was going, what direction, what song I was listening too, cabin temp, outside temp, M/B tempatures, M/B fan speeds, M/B voltages, car voltage, OBD info (RPMs, injector pulse-width, o2 levels, knock, throttle position, etc.), and be able to tell it to save audio/video to the log at will.
The tracking is nice, but won't replace the stand-alone units for security, as they're hidden and can stay on all the time, where a pc makes it impossible to trace your car when it's off. Still would be a nice add-on, as tracking doesn't add cost because there's already a GPS-receiver.
Thanks for your input and making me think!
