You left a lot of steps out of your video. Why not show us how you mounted the camera and ran all the wiring?
Perhaps if you watch the video where I show how I mounted the camera, your questions would be answered... th-cam.com/video/lpzkHvQA-t8/w-d-xo.html
@@Everlanders that's nice. How about a solution for those of us who can't afford a 3D printer? 🙄
You don't need to own a 3D printer... Many public libraries have them available, makerspaces available in most cities, or online print services such as Shapeways.com
In addition, most people are not going to be installing something like this in a custom built RV. I'm interested in installing something like this in a stock 2006 Chevy HHR. I'm guessing it was easier for you to run your wiring than it would be for somebody adding this to a factory built vehicle.
In your case it would be far simpler, just run it above the headliner the whole way to the back...
That delayed circuit tap is freaking GENIUS.
I've been chasing how to allow a safe shutdown of my carpi, and this is phenomenal.
I was given an alternative solution by a very knowledgeable friend of mine to make your own independent delay circuit.
Simply place a capacitor in front of a relay that switches constant 12v with the ignition wire. I ended up using a pretty big 22000uf capacitor with a relay that has 900ohms across the coil. That gave me about 25 seconds of delay with a 12.5 volt source before the relay switches off. Plenty of time for a clean shutdown. Of course if you can find a relay with a higher resistance you can get away with a smaller capacitor. The voltage that the relay releases at also plays a part in the time out.
You also need to place a diode before the capacitor to prevent volts from running back the other way. I also put a resistor before as well to help reduce the rush current to such a big capacitor.
Excellent work around if your car doesn't have an accessory delay or you like to crank the key out and open the door at basically the same time like me.
Came for the carPi, subscribed for the adventure camper!! Well done all around, sir!!
Hahaha same here. Saw the truck, got hyped :D Cheers!
I had this idea about 6 months ago, but i thought it would be too slow. Loved watching both your videos, you have gone to a lot of effort making and editing the video also and showing how everything works. Top Man. You know what i'm gonna press the subscribe button
Brilliant, comprehensive instructions. Thank you very much for this
.
These are by far the best videos on this subject that I have come across, I was on the fence before but now I'm pretty sure I want this
Completely awesome and well done and thought out video. Wonderfully and thoroughly explained . I can't thank you enough for the explanation of how you did it. Easy to follow and straight forward. This is how I will do mine in my 2011 kia Optima ex.
Love it! Subscribed because of the follow-up to the first video. Thanks for the scripts. I'll be installing this in my Fiero along with some other control modules for controlling custom car lighting.
This is a fantastic build! Excellent work. I almost can't believe how easy it is. Mentally I'm comparing this to building a car computer about 15 years ago, and it was an insane uphill battle! This is easy-peasy lemon squeezy! Thanks for sharing all your tools and scripts and such.
I remember the CarPC days... This is a walk in the park.
Awesome. I have been working on something close to this. I was going to do it without the cellular interface, using the GPS hat and the accelerometer hat, but your way is much easier.
I am also adding 2 additional features to mine.
1)I want to be able to remote start my vehicle using a pi face relay + . It will control automotive relays that tap into the ignition wiring cables just like an aftermarket remote start.
2) Using the same board, I want a touch screen button to turn on and off my amber wigwags.
I will definitely be referring to your setup for my initial build. Thanks again.
You cover everything I love in this world!! Keep up the good work!
The intro was funny 😄
Deadpan humor in the intro was great. That was the subscribe tipping point for me. Love this project, looking forward to giving it a go myself.
Humor? She's like that all the time...
Saw this on my recommended videos. Nice to see Canadian content like this. Hello from Medicine Hat!
Marvelous still to this day. Thank you.
Thanks @everlanders been waiting with anticipation for this video.. Great video
Love the video series. The static from back-up camera is because HDMI runs die when longer than 25ft. Most folks but an inline signal amp or HDMI repeater around every 12 ft. Hope that works. I stumbled across your video because I'm basically building the same overlander setup for my truck. Great job and happy trails!
Unfortunately the signal from the camera is not HDMI...
If it was hdmi, that wouldn't happen. It only happens to analogue signals
Great job, really like all of you guys' videos.
I found your video whilst I was browsing TH-cam and thought it was wonderful. I am in the process of getting everything together (especially the money) to convert a car to electric and think that this is a wonderful way to put in android auto. So if somebody else doesn't currently need those camera adapters, I would love to win them and would definitely put them to good use.
Awesome project! I'm trying to do something like that in my Volvo, but I'll try to take control of factory buttons. A lot of work, but I found you did more than half of it for me ;) Thanks a lot !!! :)
This is awesome! Looking forward to trying it out. Thank you for the video
Very good explanation of the system. Cheers
I love Canadian Zach Galifianakis! Seriously though, this is really great!
This is an awesome video - very informative!
So glad I came across your channel via one of Levi's recent vids, never thought of using Raspberry Pi in my campervan before 😁
Thanks and Welcome!
I think you must be a Long Lost Brother of mine. Working on 7.3 (OBS for me) and writting Script for a Pi. Seems like a good way to spend the weekend! Subscribed!
I thought the optic outlet set was backwards because I knew the output was grounded with the LED on. Then you explained the shutdown script executed upon release! Very nice and thank you.
BTW, I was so interested I ended up watching this and the part one video at home where it was very quiet and I could hear the audio well. Love your wife's bubbly personality. She adds a lot to the video. :-)
Thanks for coming back and checking it out, I had some people saying I was too loud, so I mix the audio back, I also started using headphones to set the levels of various clips & upgraded audio recorders and microphones. Perhaps I will upload some test clips and ask the people who are having problems to review them and let me know. I'm always trying to improve these videos...
Thanks for replying. Of course I'm just some random dude on TH-cam, what do I know? My suggestion would be to invest in a wireless lapel mic. I believe your mic was all the way down on the desk. If you get it closer to you then you can run the gain lower and not pick up so much echo from the rest of the room. It's funny, people will put up with the crappiest video but not forgiving at all about audio. Audio makes the biggest difference in how many viewers you get. I admire what you are doing. I'm just trying to be helpful but not in a critical way. Regards!
Parents got me a raspberry for christmas and I've been looking for a useful project to use it on. Just bought all the parts to make this with my '05 Subaru, wish me luck and thanks for the video!
Good Luck!
I looked for copper but i found gold. Thanks for this video mate.
Excellent breakdown!
Thank you for the very detailed video, I’m making a very similar setup... subscribing
Really clever mounting position
great job mate !! Love your channel .
Awesome video man. Thanks 🙏🏻👍🏻
If that HDMI to FFC camera cable adapter is still up for grabs, I'd gladly take it off your hands. Your video inspired me to fully head into this project like yours. thanks for the series
this is just brilliant. Thank you so much for being so helpful.
Glad you like!
Nice build! Thanks
Black screen problem solved. Congratulations on a great tutorial. I built one for my 2000 Ford Econoline van and everything went great until when bench testing, I plugged in my phone. It connected normally but would only show a black screen. Apparently this is a common problem. After reviewing the forums on the bluewavestudio site and trying various things over a couple of days I was no closer to a solution and about ready to scrap the whole project. Then I stumbled on a stackexchange post about loading the snd-dummy module and making sure it was referenced in the /etc/modules file. After doing that and rebooting, when I connected my phone it instantly started Android Auto and displayed the navigation view. Phone calls work as they should as well as podcast playback. Why something related to sound would prevent the display video is beyond me. I thought I would post this here in case anyone is trying to duplicate your efforts and running into the same problem I did and is looking for something to try toward a possible solution. One other tricky thing I encountered was the microphone. I got the same sound card that you show in the video, and it needs a TRS plug on the microphone which is not that easy to find on a mono microphone. My TR-plugged microphone works if I don't quite plug it in all the way but I ordered a TRS unit to solve the problem permanently. Now I need to wire up some switches and install your scripts, then come up with a suitable enclosure. My Ender 3 3D printer is too small to print a modified version of your design, but maybe I can split it in two. You are a natural at teaching and explaining things and your patience is admirable when communicating with your viewers. I really enjoy your videos.
Thanks, I don't remember the microphone TSR giving me any problems. But it wouldn't be that hard to chop off whatever plug you have and solder on a new one.
This is so dope I hope I can build this some day.
Fantastic work!
Excellent explanation with not just how, but why. Thanks.
It has served us very well for the last 6 years and 15 countries:
th-cam.com/video/Dzg1LPnY97w/w-d-xo.html
This is a cool project. I have a pi controlling my 3d printer and desktop cnc. I might need to pick up another and take a crack at this myself
thanks you did a really good job on this video.
Awesome stuff! Thanks so much!
Holy crap! Thank you so much for making this as I've been looking for exactly this. Wonder if I can split my current Android touchscreen input to control this as my android system is so old and slow.
What a bloody amazing channel, thank you !
Welcome!
Having never played with rasp pi, you give an excellent description and easy to follow video. I cannot believe she said this was boring, WOW so wrong not boring. ;^{ ) just started watching your vids and you guys are funny when you try.
This is so cool :) Thanks for the video!
Excellent job 👍👍👍👍👍👍👍
Awesome video! I love the car pi video's
Thanks for a couple awesome instructionals. I came across your videos while doing some research. I have a Transit 250 for my job which I spend a BUNCH of time in. Unfortunately I'm not allowed to modify things in it, so my plan is to use a cheap Android Auto head unit and wire it to the 12v accessory plug, and route audio into the factory 3.5mm aux jack. (Thus plug & play & no modifications) You've given me something to think about and I will be looking into a plug & play ras pi type system for later on.
Appreciate the videos!
Sounds like a plan! Check out the 10" Uperfect Raspberry Pi Screen housing combo. I show it in the intro of this video: th-cam.com/video/SjirUYghQSA/w-d-xo.html
I’d like to build something like this for my van. I’ve looked at rear cameras and navigation systems for a while and this perfect for the job. Great video again!
Amazing videos....it has given me the confidence to tackle a project like yours for my RV. Im completely new to the world of PI and was curious if its possible to use virtual buttons (ie on the touch screen) instead of physically wiring ones. If so how would we go about this? Im mainly wanting to be able to bring up your camera functions with a push of a button on screen and hopefully down the line switch between side and rear cameras the same way. I think a lot of people would be interested in this. Thanks again for an awesome video!
Love that intro!!!
Thank you very much for your video ! It inspired me a lot, again.I wish, i'll be able to share my work with you guys someday hoping you'll get inspired as well in return.Now i am going to watch your other videos ! I wish you both a good time.Etienne
Awesome.. Thanks!
That was a great opening
Very nice, I will try and make one...
pmsl she didnt look bored.. great work
excellent video! Great explanation of the scripts and really good demo of the expected performance when multitasking. Seems that it really comes down to how good your phone is. I was looking at the USB sound stick you linked, but noticed that the frequency chart they provided rolls off a lot down in the bass region, not sure how true that is but i was lookin at the HiFiBerry board for the Pi since my application is more of just a standard high powered car stereo (daily driver 2003 Camry). Looking forward to your other videos about your overlander, maybe it will inspire me to actually get off my butt and do this off-road trailer camper for my '99 Yukon.
Hey, great 2 videos so far, they have definitely helped me in the progress of my project. Until I saw your these videos, I hadn't thought about integrating a back up-camera in my set up. I don't know if you still have those HDMI adaptors, but those would really help me to add a camera to my project.
No, they were sent out to a viewer weeks ago.
Awesome vids mate.
You mentioned having front, side and rear cams as dashcams in part 1. Did you ever follow up on this?
Cool setup. :) Projects like these and the Pi3 have really got me considering playing with one. I've been wanting Ok Google to work better in my Prius, but with something more permanent, like this, I wouldn't mind patching right into the ceiling mic.
The "Okay Google" is still handled by your phone's microphone, this is because there's a specific piece of Hardware in the phone waiting for that keyword. After it has been detected then it hands off to the cars microphone.
Gj. Diggin the build!
I've got a 94 GMC 1500... After driving my wife's 2018 Jeep with Android Auto in it for a while, I will be doing one of these!
Great video!
1st - Wow. Thanks for taking the time to share this!
2nd - Ok - so, At 15:50 you are dimming the screen with buttons on your shifter which are clearly not connected? Huh? (picture cute puppy dog with cocked head here).
Lastly - Wow. Thank you for this video! I'm researching this to start a similar project and you just gave me both a resource and confidence boost!
B-Roll my good friend... :-) "Not Connected" (yet!) The clip of me pressing the buttons was recorded earlier, just after I installed the buttons. But then later when I was demonstrating that the scripts, I had no video of me pressing the buttons, so I used that clip.
Great video. Wish I had the know how to do something like this.
You do... You've just watched a step by step guide... 😁
many thanks, this time it is the last ;-) looking for you site explaining all and in particular how to setup android auto on the pi
This is my site... All the instructions are in this video...
Nice Truck! Hello from Texas! I'm building and pulling my Camper, so watching Pi videos to get ideas for camera reversing etc... However an HDMI between the truck and trailer isn't what you are covering, I'm still Subscribing because your truck looks great and you make good videos! CHEERS!
I'm a new subscriber ... I've got to be after you lost the one at the beginning 😂 🤣 😂
This is amazing. I started a project on building a new head unit for my BMW E87 that and it previously had a Head Unit running WINDOWS NT with a bad Chinese customization, and I'm researching for about a week now on everything (Single Board Computers, car wiring, sound amplifiers, etc.). One of the main challenges I was about to face was this rear view camera situation, since my old head unit had it running I want to use it too, but I had no clue on how to switch to the camera image. Thanks to you I got everything figured out now! (Btw, I'm going to use Odroid-C2 instead of a Raspberry Pi, running full Android system on it, you might want to check it out also)
Is there a turnkey Android Auto image for Odroid?
@@Everlanders Not that I know about. But there is a Android (full os) image that is officially supported. And you can also use the Ubuntu image and build Android Auto for it, but then it is not turnkey at all.
I'm planning on using the full Android OS image though.
Good luck, let me know how you make out or if you make a video showing how you did it.
Hockey Tape ♥️ it. From Northern Minnesota here.
Great channel, and Canadian too (Hi from Kamloops BC!) -- Stumbled upon it related to Android Auto, but have already viewed other segments, and you've definitely earned another subscriber!
Not knowing much about the raspberry pi and its hardware... I wonder if instead of using HDMI if perhaps using shielded Ethernet (CAT 6 or even 7) would be enough for the camera. Would remove points of conflict and simplify the run, I would think.
Unfortunately no, there are only eight conductors in CAT6 and I think they are only shielded in pairs. HDMI (and this camera) require a few more conductors as well as more shielding. Even this shielded HDMI cable I have is pushing the limits.
Brilliant videos. Nicely done. And funny. :)
Thank you sir
Like the intro 😄
Love you vids
Good Work 2.0
loooooove this channnnel
Easy to understand the Genius t shirt
Great video, can't wait for the next ones. Where did you get the mount for your shifter buttons? Been looking to rig up a PTT button on my shifter it have not found a mount like you had.
I made it from a scrap of hardwood. I have some photos of the process but omitted from the video because it was getting too long.
Bit late here but still gonna mention it.. i am impressed by the way you are using your RPI opposed to how i use it ... retrogaming... and then it clicked... since you are already running raspbian in the backround you could install a simple frontend like emulationstation and hook up a wireless controller for gaming while you are bored on the go... you could just bind it to one key button to launch it and rest is done by the controller... rpi 3 can handle everything from atari/nes/snes up to ps1. Anyways good job.
Zero interest in gaming from the driver's seat on a 7 inch screen...
Jumped over here from a completely unrelated page but he was just starting to do a build like yours and your video was suggested, free likes on both for having this awesome bit of info. One question I'm wondering about though, is there some way to get multiple camera inputs? Would love to have a front and rear camera option if I could. Maybe even a third on the top of the cab to replace the rear view mirror. Great stuff though, really want to try something like this
The Raspberry Pi only has one camera input for the 5 or 8 megapixel cameras. You could use USB cameras for the other views, but they are much lower resolution. I will have 5 cameras total, but each one will have its own Raspberry Pi and then the video will be sent over Wi-Fi or wired LAN.
Looking into this stuff to put it into my overlanding vehicle and had some info relevant to your comment.
There is also a multiple camera adapter you can get that allows for 4 cameras, and it is stackable to add additional cameras. May not be compatible with certain versions of cameras. I don't have any experience with this part personally.
www.amazon.com/Arducam-Camera-Adapter-Compatible-Raspberry/dp/B012UQWOOQ/ref=sr_1_4?s=electronics&ie=UTF8&qid=1535942318&sr=1-4&keywords=raspberry+pi+camera+adapter&dpID=41m8s9EsWoL&preST=_SY300_QL70_&dpSrc=srch
Everlanders Did the adapter below work out for you? I’ll be looking to see your results, as I’ll need four or five cams as well and I don’t want to use WiFi
@@Everlanders if you're only switching between them and not looking at them all at the same time you could take advantage of the fact you are using HDMI cables for extending and use a HDMI switcher. Just open it up and connect the source switching button to one of the IO pins on the Pi to trigger it. Could be a cheap alternative for a camera view switcher.
im running both. i ran the backup cam like he did and a web cam for the dashcam. Using motion for the dashcam recording and then use proftpd to allow me to connect over wifi and pull the video.
Hey I’m very impressed of your ability and knowledge dammit just share more thanks
I'm also working on a similar project except mine will be connected straight to the wiring harness and completely replace the stereo system. I have the prototype of the build completed and am just waiting on a few more parts to arrive before completing the final install. Looking forward to video 3!
Yes, in that case you just need an inexpensive amp.
I just ordered my first pi ounce three weekend and a monitor. I'm going to try to do this for me car ahs of turns out good I'm going to build one for my semi. Thanks for the great ideas.
Epic video, thank you for the extensive details
Nice! Thanks for this video. The backlight script is great and the buttonmonitor script will be a great starting point for me to be able to select one of several cameras to view...if I can figure out how to get usb video on the pi! I had to use crontab -e to get the scripts to autoexec on boot.
couldn't get anything else to work. Running Buster and Open Auto Pro on a rpi4b. Just about there with my truck computer!
Done anything in the TPMS area?
Very nicely done! I'm curious, did you ever find any more information on your multi-camera always-on DVR?
I'm using a Pi at every corner/camera and using MotionEye for now as my camera DVR software.
Good deal bud. Because of your video im am going to build mine.
You're a wizard!! Have you considered using a USB powerbank with passthrough? That way you could cut the power to the screen and delay the shutdown script for a 5-10 minutes. Then when you stop for gas you don't have to wait for the system to start back up.
You wouldn't need the battery bank for that, just delay the shutdown for as long as you want, and about the shutdown if the ignition comes back on... But it's really not an issue, it boots up fast enough for me...
your information are too good and useful...great job
so siick dude! I wonder if you can get a bigger screen and then split screen the back up cameras and such or even have a obd2 monitoring app running along side
You sure can.
I would love to see you set up an OBDII reader to your raspberry pi!
Others have done it, I don't think I'll bother, we use the Torque App to monitor vitals.
You could have used a Hi-Fi hat for audio in order to get superb audio out of your raspberry pi. Again awesome build.
I could have, but have no interest... This rig is built for off-road usage with a big block turbo diesel, you can't hear yourself think let alone the difference between the Pi's built in DAC and the Hi-Fi hat...
0:20 ok, ok... subscribed...
You could use an light sensor to automaticly adjust the brightness.
Btw awsome project!
Yes, you should do that.
Hi - I'm doing something similar, but I'm having issues with vibrations. I haven't been able to track them down (noise on screen and OS glitches, etc), but I've held the SD card, power connection, etc. Have you had any issues with vibrations, etc, and if so, how did you solve them? BTW, great videos - content and presentation - thanks so much for these!
Subbed for that hilarious intro
