  • Returning to MP3 car after 7 years

    Ok guys,

    I've been out of the loop for about 7 years, built my carputer pre-PAD/Table days. Now trying to get back in it to put a new system in the car. Not sure where to start or if I really want to put a PC in the car now that there are Tablets and IPAD now. I am not really a big fan of the tables and pads in that you have to always have to buy an app. I like the fact that on a windows or linux machine, I can use the purchased sw on multiple pc's if needed. Anyhow I am looking at a 7"(HDMI) screen that can be seen in the daytime, fast boot time, navigation, internet, and something that can run off 12VDC.

    Any ideas where to start?

    Also, I am seeing the Ardurino controller, why so many versions and can it be integrated into the buy of the shelf software such as Centrafuse?

    for a screen , I bought a pretty cheap led backlit lcd with touch without a frame , I am amazed by the sunlight readability

    www.njytouch.com

    I know its Chinese but everything is Chinese :P , they do have good customer support

    for fast boot times , depends on hardware but I find having windows 7 embedded helps a lot , also very easy to change the logon and bootscreens on that.

    I say going for a motherboard with embedded cpu like atom dual core or amd e350 , something like that

    also SSd are nice to have these days




    edit:

    Arduinos are in many different shapes and sizes , but they have different functionality like the amount of analog and digital ports

    If you see my worklog you can see an example for arduino use, but basically if you have the patience and skill to work with them you can do almost everything with them.

    My next idea is to use an analog port for the dimmer , when I turn on my lights the screen goes to night mode.

      Hey welcome back! Not sure what vehicle you got but for a good monitor I use the http://store.mp3car.com/Lilliput_669..._p/mon-123.htm Fusion brain or phidgets would be better for front end support SNO

        I'm new to car pc's but after assembling my first one, I already started scoping out what components I want for the next one.

        I know it's priced obscenely, however I want this 7" 1280 x 800 screen with the 1200nits LED backlight with multi-touch capacitive and extra video input options for $644

        I was thinking I could do just fine with an Intel NUC barebones unit

        Stuffed with Micron's Crucial 256GB mSATA drive and Crucial 16GB DDR3 memory kit

        Power supplied with the Mini-box DCDC-USB-200 Intelligent DC-DC converter

        And last but not least, an ODAC USB D to A converter board to get 2V RMS line out of the NUC.

        This stuff would give me an extremely low power, yet high performance solution that could feed the highest quality audiophile's sound system, and the screen would be a visual joy to use.

          There is so much more from when I was doing this oh so long ago. I guess my biggest thing I am looking for is a good power supply for powering up the MB. Back then I had an Opus power supply. Are there now DC to DC that Power up DC power supply built into the motherboard. Definitely a display where the sun doesn't wash everything out and I would like to the display to swipe to left, right up and down. I know that this takes a capictence type of touch screen to do this. Are these type of screen available for the carputer yet?

            I think the tablet installs seem to be much simpler, less components and less power demand. It depends on your apps also, there are alot of free apps and the ones that you may want aren't all that expensive. In my case I'm torn between the 2 but leaning more towards a tab now. I started a carpc build many years ago and never finished it, i still have the parts. The only thing I need a carpc instead of a tablet for is to do some tuning. If they ever get, or someone writes an app that can run tuning type setups like emanage, aem fic, and zeitronix components I could go 100% tablet. I'm sure someone can figure it out because these things use usb. The nexus 7 looks really good and has hi def capacitance touch.

              Yeah... I am starting to think a 7" tablet slate. I have a a windows slate now. Only thing I worry about with a slate table is running so many USB devices off of it. I would like a slate with a front end to launch from the Windows8 Also how to interface a back up camera too switch when in reverse. I think I will experiment with my current slate and put my old car pc in for now.... I can roll with crappy system until I figure out what I want to do. But if I can Music, net, GPS, back up camera, all seamlessly I will use a slate. I need to start investigating on slates that have an HDMI (MHL) output, at least 4 USB.. Or a USB hub that can be powered by 5 volts..... As I type this I think it may be easier to use a tablet.

                Well I found out there are really any 7" tablets out there. So I decided I am going to go with my existing Slate that has HDMI output, connect that to an indash sunlight readable Lilliput double din. My only concerns are how many USB hubs can use. I need about 6 to do everything I need to do.

                  I use 11.6" exopc windows 7 tablets along with a ram mount 6 port usb hub for a client of mine in their transports. Never a problem with the hub or anything I plug into them. The drivers love the bigger screen being in a big rig. SNO

                    I had an Android head unit for a year, and overall I hated it. It had 2 USB's but no USB Host mode, so could not enumerate more USB devices, and was extremely slow reading song lists off flash drives. Often I would have to eject the drive then re-mount it, and wait a few minuted for my song list to read. More than 4GB, wait more than 4 minutes! Boot time was slow too.

                    Not trying to bash tablet installs at all, but the slow media read times, not being able to plug in a USB hub or connect a USB DAC for better sound quality (some tablets support this with propitiatory software), and no easy way to add other hardware means the PC is still the most flexible solution. You can also download the free Bluestacks software to run all your android apps on a PC.

                    There is concern with USB. Tablets need USB hub support, and USB DAC support

                    Android and iOS are the concerns here, not PC based tablets.

                      OH boy! so much has changed! Your head is going to spin!!!!!!!!!!!!! I opted (finally) on a Windows 7 / Android based system. Windows is only used to control things like screens, amps, etc. The user though only interacts with the Android PC on a stick devices. Each seat has one, and there is one for shared use. Rather than fight to use my resistive touchscreens (that do not work with these units), I simply unplugged them and bought battery powered mini track pad/keyboard combos. Testing has yielded they are easier to use than a TS. The driver gets a TS, but that's built into the tablet.

                      In all anything Android, and or iOS based is the way to go. There are just so many mobile friendly apps. I cant recommend Windows 8, in my opinion, its pure garbage. An obvious get people's money rush job.

                      PS: rray, most late model Android devices has USB host mode. Its turning into the standard, because users want more out of their devices. 7 of the Android devices in my install have Android Ice Cream Sandwich 4.0. All with USB host mode. Then the 8th has Android Jelly Bean 4.1, it also has USB host mode. I was able to reuse so many of my USB devices from my Windows based car pc days. Anything that I couldn't port to Android, the Win7 system makes available to Android via network, example GPS.

                        your final choice will likely depend on the earlier discussed factors , usb peripherals and customizability or mobility and less hardware to worry about.


                        you may have more factors in mind but thats what I could think of that define the options pc and tablet from the top of my head.

                        personally I would go for pc at this point in time given the hardware and software options out there right now.

                        I will keep an eye out on the tablet market to see if there are any interesting developments.

                        Right now a pc is the only device that I can customize easily, upgrade if needed and does everything I want it to do.

                          Hello, I'm actually a lurker that's been around for a long time. I was using the forum "back in the day" like you were for research purposes. My thoughts (I'm WIP with my Car PC right now):

                          A) Installs are simple(r) now if you want them to be. IMHO, lots more pre-fabricated/off the shelf parts. You will still have to do custom fab if you want something... well... custom.
                          B) 7" HDMI screen --> Lilliput 669. It's only resistive touch. From my exhaustive searching, it seems like implementing a capacitive solution is rather cost prohibitive. From what I've found in the last few weeks is that the driver isn't supported (correctly) in WIN8, I imagine SOMEONE will figure that out soon enough...
                          C) The Arduino is a microcontroller, not a micro computer. It is used more for hobby projects, automation, and "real world" interfacing. It is NOT going to run centrafuse, as it's not a "PC." People use these more for robotics/sensor based projects, etc.
                          D) I'm currently in the process of building something similar to what you're looking at [will detail hardware below], but I would actually reconsider the tablet route. It has the potential to make your life REALLY easy. "Sideload" apps if you want to try them out first. There are many free options for many things you're looking to do (NAV, music, etc). I'd take a hard look at tablets, as they can be drop in and go solutions. With that said, though...

                          I'm currently building my CarPC with an Intel NUC. It's a 4"x4" motherboard in a tiny unit. I'll make the disclaimer here that I'm an Intel employee, so I'm biased. With that said, though, the reason I went with the NUC is that I wanted to build everything into a DoubleDIN slot, and Mini ITX wouldn't fit. There's also the bonus of having current gen architecture with a lower power envelope than I would otherwise get, too...

                          My hardware includes:

                          Lilliput 669GL HB HDMI
                          Intel NUC (2 HDMI version)
                          Intel 6235 WWAN mini PCIE (includes bluetooth)
                          2x 4GB ADATA DDR3 SODIMMs (Didn't feel a need to go 16GB)
                          Crucial 128GB mSATA SSD
                          Bybyte DoubleDIN frame
                          Metra VW Dash trim adapter with the bottom trimmed down to accept the Bybyte frame.
                          Carnetix P1900
                          Asus Xonar U3 USB sound card (the disadvantage of the NUC is that there is no analog audio out. You can use a DAC or a USB sound card. I opted for the sound card. Haven't determined if this was the right route or not..

                          I'll note here that the NUC actually runs off 19V, which is the reason I chose the Carnetix P1900. It takes 12V in from the car, converts to 19V, and then also has a secondary output for the 12V your LCD will want. You can add on the 5V tertiary supply, which appears to be a simple voltage step down convertor (supports up to 3A).

                          My gripes: I wish there was a capacitive 7" touch module that was readily available and at a reasonable price. Most of the ones I'm seeing these days are in the $120+ range just for the digitizer and controller. When I was researching panels way back when, the 3M modules were going for $40-60?? It's a bummer I didn't blind buy one back then. The Lilli has issues with WIN8 that greatly reduce the usability, so I'm still looking into solutions there.

                          IMHO the above hardware (add on a bit for added peripherals) is crazy good for car PC usage. Fully solid state, no moving parts (minus the HSF), tiny (easy to place), reasonably low powered, and easy to integrate (Carnetix 1900 has you covered). Insane performance for the form factor, and RAM is cheap. Obvious disadvantages include minimal/non-existant expandability (unless you get the Thunderbolt enabled one, which can run pretty high end hardware once there's actually support and devices that USE it). That's just where I'm at after "returning" and actually starting to build something after a similar time frame. Hope this helps some.
