Intro: Adding a computer to your car (CarPuter)[Featured in the February 7th Newsletter!]

I did this project several years ago, and posted it on MP3Car.comI have learned alot about carputing and this instructable will be about both the installand how its been using the carputer these last few years.

This is my 2007 Honda Element, before I attacked it with Soldering iron,wire cutters, dremel tool and other weapons of mass media

step 1:PowerPortsOne of the most needed item in any road warrior's arsenal, is powerports (or if your over 40 they where called "cigarette lighters") so I added two additional ones - onthe dashboard, and one in the center panel. this was actually a easy mod, with me just stealing power from a "only power when ignition is on" line f rom the car.

step 2:USB PortsThe second most important item is USB ports, more and more devices need USB powerand all devices "Talk" to the computer via USB - So I added a Powered USB hub in my gloveboxwith a 15' USB cord to my computer.

step 3:The Front End / GPS SystemWhen your driving, you need to keep your eyes on the ROAD.not on a computer screen, so my front end had big descriptive icons that where easyto touch, and access, with minimal eye time away from the road

The Buttons: (reading counter clockwise)Photo library - For showing off pics of the build, etc to passengersMac control button (settings / other computer access)Time and (green button) Wi-fi enabled and joined to a networkitunesMovie player - Awesome being able to throw a movie on while waiting for my mom shopping!Car access system (diagnostic computer interface)Available button for other features (like window control etc)

step 4:Rear View CameraI mounted a Back up camera in the rear, so when I put my car in reverse no matter what mode the screen is on, it went to the back up view.

step 5:Power / Reset ObsessionAhh me being Obsessive again, This project is where I spent more time and more revisions ti llI was satisfied. All this does is reset the computer if it crashes, and glows when the computer isin "sleep" mode (it also doubled as a 'Security' light when the car was parked)

step 6:The WiringSince I was running wires along side airbags and other passenger safety devicesI decided to let a professional do that wiring.I built the harness beforehand, and then they wired it in for me.

step 7:The Console and USB CamHere you can see the whole setup - the video is a live conversation I was having wi-fi withmy friend phil. and below I will describe the pictures in detail:

First Picture:The front, you can see the mac mini mounted above in what was a place for glasses,all the wiring sits behind i t with a cutout access panel.to the left of the rear view mirror is a USB webcam hooked in.One of the ideas I had was to mount a frontview camera as well, and if there was a accidentautomatically record the incident (trigger from the car system) but never got around to doing it.

The center console with a pop up touch screen, that was hidden when the car was parkedThe computer is also out of the line of view, and when my car was robber last yearthey didn't touch the computer. (prob didnt even see it)

Second Picture:

The remote on the left controls a Built in GarminGPSsystem - which pumps the videoto the same screen, To have everything integrated I could not get a touchscreen unitso to enter in destination data I use the remote.

Third picture:This is the roof of the car, the back antenna is a radio :)there us a wifi antenna as well as two GPSantennas (one on top, one in the front)the wifi antenna on top added about 500' or extended range to my wifi(enough time to find a open wif i, download mail / updates to my computer)(this was before EVO cellular internet was a viable option)

Picture four:Just the car, I love my car.

step 8:Voice Navigation DemoShowing off a voice activated GPSI added to the system.it was fun having the garmin and this system argue over who had the better directionsI'm being filmed with the built in webcam and recorded on t he mac.

step 9:The FutureThere is a line of portable laser projectors coming out, www.microvision.com/showwx/ and I am thinking of removing my screen and going with a heads up display and air mouse, or even something more eclectic

I know that most "upscale" cars have voice controlled navigation, and a entertainment consolebut I did this 3 years before they where available.

This looks awesome (except for the fact that its a Mac, but that's personal preference).

MacGeek,Quick question, so do you ever unhook the monitor, and are you not worried about someone breaking in to your car to steal the computer?I live in a city where breaking windshields to steal GPSunits seems to be a popular sport, so I would be worried about your setup...

the monitor slides into the dash, so it looks like a blank spot.

Don't worry they did the same to my car, and stole my Garmin!

MAC!!!!!

mac, pc, linux chrome OS... they're all the same.

soulsnax says: Feb 7, 2010. 7:42 AM REP

who cares if it's a mac or a pc? They're both the same!

itsthatsguy says: Feb 4, 2010. 7:59 PM REP

this as cool, then i realized you used a mac and well, i rated 1

itsthatsguy says: Feb 4, 2010. 8:00 PM REP

sorry .5*

troppoforte says: Feb 4, 2010. 7:54 PM REP

One thing that is bugging me; which Garmin did you use and how did you find the connections on the board to connect it to the big display? Also, youmentioned the power button is useful as a anti-theft device, but you also said the power for the computer is only on then the ignition is on. How is thatworking? Or is it?

Ihave been optioning this project for my '95 Volvo 850 wagon because it needs some automation and ease-of-use added to it since most of it is analog (nothat that's a problem for me 'cause Ilike my cars that way) and I'd most likely be using a Windows-based device since Windows usually has the most third-party accessories available. But I LOVE Mac computers! Ihave 7 of them, including an Apple IIc.

The biggest issue Iam facing is f inding which wires are the 12v power and so on. Did you have a schematic for the Element? If so, where did you find it?

mrteesk says: Feb 4, 2010. 7:49 PM REP

Very nice install! The Mac Mini is a great platform for this kinda stuff.

texhon3 says: Feb 4, 2010. 4:01 PM REP

cause thats what I have and a netbook is out of reach

CanWire says: Feb 4, 2010. 3:15 PM REP

Why not just use an inverter and a netbook? You could still use all of the usb extensions/hubs, run a small vga (touchscreen?) monitor, and have poweroptions for standby when operating on batteries. For more monitors configured, there are also cheap usb monitors.

CanWire says: Feb 4, 2010. 3:18 PM REP

actually... why not just install a laptop slot with connectors for power, vga, usb, ect... within your car would just be peripherals as an extension of yourexisting laptop. Cheap, easy, and powerful.

texhon3 says: Feb 4, 2010. 1:36 PM REP

This is somethin I have wanted for years ! I have a small format windows computer for this project .I drive a 2000 Dakota. This is way cool

Very cool. I am WAY over 40 (my daugher says I'm "officially" old with this b'day) and call it a cig lighter (I'm going to change to "powerport").

Since my own son doesn't speak to me, maybe you could adopt me and work on my car?! ;-)

macgeek800 says: Feb 4, 2010. 10:15 AM REP

i'm 51 - Would Iget strange looks calling you "MOM"?

Bmarygirl says: Feb 4, 2010. 11:31 AM REP

In this day and this society? ! People would just think your father married a much younger woman ( and I am older than you) or you could be myyounger sibling or..........

BTW: I've ridden on the Cyclone.

billb says: Jan 28, 2010. 6:12 PM REP

Very cool project!Could you explain more clearly how you got GPS on your Mac.The only GPS App. I know of for the Mac is "Route Buddy".Its expensive and isn't nearly as polished as "Microsoft Streets& Trips" or "Delorme Street Atlas" both for Windows.Thanks.

XsavioR says: Feb 4, 2010. 11:25 AM REP

I dont use mac at all but a bunch of devs I work with do. Couldnt you use whine? emulate windows and then use the standards rather then all the jazzsuggested here.

@ poster (suggestion)Clear mobile broadband (as low as 35$/mo no teeth contract, no teeth = no cancelation fee if you purchase the 50 $ usb dongle)

rfid tag system to utilize car / onboard pc / windows / locks / trunk.

Blue tooth link to pc , Pair cell phones to the onboard system utilize car audio (via inputs on the radio) for hands free.

but hey im just a geek with too much time on my hands (proud of it too) :)

macgeek800 says: Jan 28, 2010. 7:14 PM REP

hey Bill,

I cheated ;)

I bought a Stand alone garmin system, (buy.garmin.com/shop/shop.do)and it runs independently from the mac, i have never seen ANYDECENT GPS program for the mac (and I am still waiting for a GPS driver that wouldtalk to oo le maps on the mac mini)

billb says: Jan 28, 2010. 10:52 PM REP

Their is a way to do it. First buy and install "Google Earth Plus" then connect a USB NMEA compliant GPS antenna. And install a KML converteralong with another couple of Apps and your all set. Yah, I haven't bothered either.

Though their is this: http://www.axiotron.com/index.php?id=techspecs

I wounder how THEY do it and how well it works.

Thanks for your reply!!!

kingbirdy23 says: Feb 2, 2010. 5:45 PM REP

How did you set up the USB hub? you just said you added it, so I was wondering, did it draw power from the power port (lighter thing), your computer, orwhat? and how did you install it?

macgeek800 says: Feb 4, 2010. 10:16 AM REP

i found a 8 port Powered USB hub that was 12vDC inputSo I just hooked it directly into my System (on when ignition on)and it converted the voltage to 5v.

I kept breakingthe USB sticks off mystereoso I connected a USBextension cord under the dash. Don't have a glovebox. Had to take it out because Iwanted my amp mounted therein case of unwanted visitors.

I am 16,don't smoke and still call it a cigarette lighter.

CraigSnedeker says: Feb 2, 2010. 3:07 PM REP

Wow this is cool! So what did you do? Plug in your computer into your car (basicly)? Did you have some sort of USB-to-"cigerate lighter" converter?Someday I'd really like to do this :D Idon't use Mac tho, I'm a Windows user =P lol

bpfh says: Feb 1, 2010. 12:48 AM REPGood start but lacking in details.... So a few questions to clear things up :)

- Can you post a link to what you did on MP3Car.com?- How did you interface the screen with the mac?- How did you get the reversing camera to work with everything?- Is the satnav system installed on the mac or is that an independant system?

Cheers,Daniel

macgeek800 says: Feb 1, 2010. 4:11 AM REP

Here ya go!

http://www.mp3car.com/vbulletin/worklogs/93913-elvira-scare-e-lement-honda-element-07-a-3.html

The screen has 1 VGA input and 2 Composite inputs,with a "camera 2 priority" that means if Camera 2gets a video signal it will switch to that input no matter what(Backup camera, with power supplied when I go into reverse)

Vid #1 - VGA - MacintoshVid #2 - Garmin NavigationVid #3 - Backup Camera

any more questions?

Andy-K says: Jan 31, 2010. 9:02 PM REP

Nice project. I think if I ever do this to a car of mine, I would want to invest in a mobilebroadbandsystem, so I could have a 3G connection while drivingaround. This way I am not tied down to WI-FI.

HolyTracker says: Dec 31, 2009. 12:16 PM REP

Great looking ride! But there´s a lack of instructions... How did you do it?

macgeek800 says: Jan 1, 2010. 5:14 AM REP

I did this in 2007-2008 Long before I joined instructables.So I didnt actually track the install, But Iwill be happy to answer anyquestions that you have!

Jonathan

kerns says: Jan 30, 2010. 7:51 PM REP

When you mention "large icons" - do Macs offer large macro-fronting icons like that as standard?From step 3 Iassume you're using a touchscreen - what front-end software are you using, an Apple OS?

onlywhenprovoked says: Jan 29, 2010. 4:03 PM REP

Hey, I'm only 37 and I call them cigarette lighters. lol :P

I'm going to go with the other comments and say, lack of instructions on how to put a computer in your car, It really should be named something like put inaccessories for your carputer, the part of putting in the actual computer does not exist in the instructable. Even with putting the accessories in, about 80% imissing and doesn't really show us how to do anything really.

madmikeee says: Jan 6, 2010. 7:53 AM REP

Nice project but you really didn't instruct us on anything. You showed some wiring but not any configuration for the PC, mountings, interfaces etc.

macgeek800 says: Jan 6, 2010. 9:06 AM REP

As I said before, I did this project in 2007

I didn't have the forethought to photograph the whole procedureI will be happy to answer ANYquestions anyone has

Wicked project! Am surprised that it is not Linux, as is the fashion among most Instructables projects. I can see this going down many, utterly pointlessroads.

macgeek800 says: Jan 5, 2010. 4:45 AM REP

Well, if you look at the Licence plate, you will see WHY I choose the macmini.

Jonathan

JavaNut13 says: Jan 5, 2010. 1:42 PM REP

I can see that you wouldn't even consider using a Linux box in your car, even though most people who put a computer in there car would use Linux

loudboy says: Jan 2, 2010. 4:05 AM REP

Looks great!

How are you powering the MacMini though? Does the Element have a built in inverter with enough power for that, or did you add your own? THanks!

macgeek800 says: Jan 2, 2010. 5:36 AM REP

Ahh yes, I forgot about that completely!I have a Smart power inverter (made to work in a car) calledCarnetix P1900, not only does it provide power for the mini it also hasintelligence, to keep the mini in sleep mode, and also monitor and power

other items connected to it, Its a GREAT product
