Hello everyone. I have been searching for threads all day and have not found much information about being able to hook up devices into some kinda of USB interface or serial interface on Android devices. The closest thing I can find is this: http://forum.xda-developers.com/showthread.php?t=1202082
There has to be a host controller on these phones right? I would think that if there is a micro SD read reader on the phone, there would be one. Am I the only one thinking this? What is the best way to find out?
My inspiration comes from the ArduPilot project . I think this is pretty sweet but I think it could be way more powerful with a full operating system versus a limited micro controller. An additional fun link of, what most can imagine, my final goal: http://www.wimp.com/helmetcam/
I am posting this on the Evo 4G general thread due to owning it and it would be easy to disassemble, if there is something I need to look into.
I want to look finding (or creating) a robotics application for the android OS to map *connected* servo controllers (not bluetooth connected, Arduino powered, etc..) that will also allow remote users to control the phone multiple threads to control the UV or UAV. Examples: 1: Flying the RC Plane while viewing the video stream on the phone's multiple cameras (integrated or attached). 2: Executing autopilot application and monitoring it's progress through two-way communication from a controlling "base" station (PC, Server, Tablet, etc..). Maybe executing multiple RC vehicles at once.
I have a feeling that this would help many others with other types of monitoring projects (What comes to mind: Home security, Car Security, garden monitoring, etc..) This could also help the creation of other commercial products.
Any input and direction you can give would be appreciated.
After seeing a video where you can control a parrot AR.Drone 2.0 with the shield I started thinking up ways to control a real car with it.
Probably wont attempt this but I like the idea.

main problem i see is when shield's battery runs out.
and i wouldn't want to try it until its out beta, otherwise it might lose wifi connection lol

most cars have a 12V socket in the cabin somewhere.....
Otherwise, this is doable.
Dependant on the age of the car and its level of security (engine electronics wise) you could either tap into the engine management units, braking and power steering (power steering alone can actually steer the car with no user input, IF the system allows it or can be modified to be controlled externally in that way, same goes for many other areas of the car) or take a direct hardware approach. Some actuators bolted to the pedals and steering wheel could easily be controlled with an arduino which can then pair via bluetooth, wifi or USB to the shield (USB would be cheapest but would prevent charging from the car lighter socket and of course mean you would have to sit in the car and might aswell drive anyway).
Cars controlled via other means have been done frequently anyway. Your only changing where the input comes from. Your idea isn't really that insane, but I wouldnt want to try it.
As for loss of power/signal. You would require some sort of "computer" aboard the car anyway. Even if its just a simple 8 bit arduino, in fact let us assume that it is an arduino UNO R3 for some reason, even that measly little 8bit CPU can be setup easily enough to detect the loss of communications with the Shield and cut the engine, engage brake etc etc.
I have a either a pandaboard es or a rasperry pi model b I can use. I am not planning on being in the car I am planning on mounting a camera about where the drivers head would be and streaming the video form that to the shield.
As for the car I am think about using a gutted 97 camaro for that, and adding a carburated 350 and some automatic trans. the most advanced computer on the car will the one to radio control it.
As far as usb power is needed there are 5 volt dc-dc regulators for cars that supply 1+ amps.
edit
Yes I know I would need to avoid running myself over.
Either one would be adequate.
I'm not a car wizard so couldnt say whether or not that camaro could have its systems directly tapped into by the pi/panda but either one could control actuators mechanically connected to the steering wheel and pedals.
As for the auto transmission, I despise the very idea of an automatic transmission and have never set in the drivers seat of an automatic vehicle let alone driven one (unless you count a 50cc scooter with a CVT). But in the case of a small computer controlling the car, probably a good idea to reduce the amount of things it has to do.
I have a twin USB adaptor in my car, max 2A shared between both sockets although that does appear to mean (with my non scientific tests as I dont own a multimeter, really need to get one actually) that with only 1 port active it can supply 2A to that port. I think it may just be a straight 12v>5v @2A converter with 2 USB's in parallel.
There are plenty of linear actuators available, for the steering a windscreen wiper motor from a truck, a pulley and some sort of feedback mechanism would be possible.
Would be a cool project, if somewhat dangerous if you don't know what your doing But get online, its been done.

the car currently has no interior at all
no engine
no transmission
no hood
no side windows
no steering colum
no pedals
it maybe missing some brake parts.
it is gutted.

Guys who might be able to help you best are probably over at letsmakerobots.com
I am a regular on there although only with 1 submission, 2nd on its way.
I'm no guru and with a project with a potential for some danger I think its probably best to not take anything I say as gospel, other than that it is possible and that the raspberry pi can probably do it (I have already used the pi for running 2 motors with speed control, a servo and ultrasound module with no issues, python plus RPIO).
should i make this
or this
then?
Hello,
I would like to hear some opinions about my personal want-sth-to-do project. I want to use NFC to open my house doors, including the front door, garage and bedrooms door. In addition, I want to be able to control my air-conditioning system, TV and audio system. I want to integrate some sort of IP/CCTV cameras into my personal system. Just to improve the system, I will develop a Android App to control it via an API.
So, to make this project possible, come to my mind three ways:
1. [Arduino]
- Using the Arduino and its shields to develop the entire system. It will take a while and be hard in some points such as IPCAM recording.
2. [RaspberryPi + Arduino]
- Using the RaspberryPi connected to some Arduino shields using the GertDuino (GPIO expansion boards that make RaspberryPi compatible with Arduino Shields).
- This options seems to be the best option for now, but I dont know if RaspberryPi is able to handle the entire system.
3. [IOIO-OTG]
- IOIO-OTG is a board that make any android device as the heart of the system, making you just program in Java and control the GPIO and UART.
- The benefit is that I can develop it using some Android Stick, however, I need to search about available shields for it.
In addition, I need to think how to separate the core of the system from the sensors such as nfc readers. I do not think that wiring over the entire house is the best way... but I didn't found any wireless sensors...
Someone want to give some opinion? I will update the thread with the sensors I'm looking around and so...
I'd go the arduino (maybe more than one) + raspberry-pi (maybe more than one) way.
the ioio seems to be some µc that runs a firmware that connects to android and provides all i/o pins to android... so nothing you couldn't do yourself with an arduino or something similar.
I'd start with the devices you want to connect. Air conditioning might be controlled using Infrared emitters - would that work?
NFC Readers can be built from an arduino AFAIK, but you'll need some sort of field bus or wireless connection between all the parts...

I find your ambition high. But as someone running an Insteon Smart Home with an ISY994i, I can't help but feel you are trying to make a fairly cost effective and secure option more expensive and less secure. Mobilinc integrates with tasker, so you could set it up to unlock doors and stuff pretty easy with NFC.
Best of luck with your search.

I agree with DThought. Including a Raspberry Pi would allow some pretty intense processing power.
If you want to limit the amount of wiring you do, you could actually use a USB wifi dongle on the Raspberry Pi. You could then make some simple protoboards/PCBs with an Arduino with a wireless shield for each thing you want to control. This would likely be a more expensive solution than plain wiring but it would allow a lot of flexibility. Especially if you had each of the Arduino clients very similar so that they are interchangeable.
You could also try using Xbee Arduino wireless shields in case you don't want to use regular wifi.
This sounds like a very good project. I hope it works out for you. :laugh:
Nexus 7 (2013) tablet install in the dash
I've pondered this install for over 2 years and finally decided to go ahead with the install.
I had originally upgraded the sound system in car by pulling out the stock Nakamichi Head Unit (a couple of years ago) and replaced all the wiring, speakers etc with decent components - Mid and tweeter (separates)- Focal speakers in the front door and a 13 inch Focal sub in the trunk. I focused this upgrade for an SQ setup and did not install any speakers in the rear on purpose. For amps, I used two Zapco's (one for the fronts and one for the subwoofer)
I installed a Pioneer AVIC-D1 navigation/Head Unit and also installed tons of sound deadening all over the doors, trunk etc.
Fast forward to today and here is my new setup - since I had upgraded the wiring and speakers already, I focused this build on the Tablet install and a new HU that connected to my upgraded wiring. I then connected the tablet via the USB DAC (the Microstreamer unit) to the Head Unit aux input for audio out to the car speakers/amps. This simplified my install as I only needed to focus on the tablet install and the new Head Unit Install. Needless to say I ripped out the Pioneer unit for this install.
I flashed Timur's kernel ( https://timur.mobi/timurs-kernel-n7-2013/ ) for a fixed install as its perfect for these types of installs - the tablet goes into a deep sleep mode when accessory power is shut off and it loses very little charge overnight (roughly about 1 - 2 % per 10 hours). As soon as you turn on the car, the tablet senses power has been applied and the screen comes on immediately. So even though my install allows me to remove the tablet from the car, I don't really have to remove it. It comes on immediately when the car is turned on and goes off (deep sleep) when the car is turned off. You don't need to setup any complicated (for me anyway) tasker routines to take care of this. I then connect my tablet to my Note 3's hot spot for Internet access.
I had the install done professionally - the custom fabrication of the tablet and Head Unit mount. That was really the main part of this install by Ultra Auto Sound in Mississauga, Ontario ( http://ultraautosound.com/tag/nexus/ ) . They did an excellent job as you can see from the pics on their website and below. Thanks Joe!
I haven't been able to get the backup camera to work yet with the tablet as my understanding of how it works with the tablet was not thorough enough and I need to do some more reading to figure it out properly.
Here are the parts I bought:
Nexus 7 (2013) tablet ofcourse
Head Unit - Kenwood eXcelon KDC-X998 CD Receiver with built in BT and HD radio - its one of the better Head Units on the market right now ( http://www.amazon.com/gp/product/B00I8S6B86?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 )
USB Hub - DLink 7 port USB hub ( http://www.amazon.ca/D-Link-DUB-H7B...d=1439314404&sr=8-1&keywords=DLink+7+port+USB )
USB DAC - HRT microStreamer ( http://www.amazon.com/gp/product/B00B4YE5BG?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 )

The install looks great. Good job. I've got a 2011 GMC Sierra that I've installed my Nexus 7 (2013) in the dash. Turns out that the double din after market head unit adapter plates opening is just a hair bigger than the actual LCD. ( not the whole tablet but just the LCD). So I was able to use it with the Nexus mounted to the back of the adapter plate so that it fits tight against it covering the edges of the tablet and only leaving the LCD exposed. I'll take some pics and upload them soon. Good job on yours. Love seeing how others went about their install.
nice built but may I ask, is it really needed to add an usb dac to the instalation process if I am runing audio from the tablet with 3.5mm audio jack cable to the car's player aux ?

Thanks. I love the setup as is and the audio shop that installed it recommended mine be setup (the mount) like this because of my requirement of wanting to be able to unplug it or get to the buttons for whatever reason. I personally prefer the look that you went for where the tablet is behind a plate as that looks more OEM than mine.
Mine looks so obviously like a tablet on the dash even though the quality of the audio shop's custom mount is good, it still doesn't look like an OEM screen (when its behind a plate).
My installer said it would be more expensive to mount it behind a custom opening and also make it removable at the same time, hence the end result you see here.
Looking forward to seeing pics of your setup!

No you don't have to do what I did especially if you are not pulling out your stock stereo.
great ! thanks !
This is awesome and has inspired me to create my own Nexus 7 setup. Great stuff!
how did you make the august vgb100 work with the nexus , I bought it and the tablet couldn't recognize it.
Hi, could you share related .dxls file. I searched for LFA skin, bu it dosent look exactly like yours ?
Thanks.
EDIT: Sorry, I found lots of LFA skins, its ok!
What app are you using as the "dash" app for nav and such. Looks very android auto'y

I could never get the backup camera working and that bugs me.
I'm having second thoughts about the whole system now and want to get an Android Auto HU such as this one - http://www.crutchfield.com/S-Xvsy2Zazrje/p_1304200NEX/Pioneer-AVH-4200NEX.html
What is your budget and requirement for the install of a tablet in your car? The obvious ones in terms of requirements are Phone calling/receiving, Navigation and listening to your music collection. Any others you have?
If your budget can swing for the unit above - it has very good reviews, I would just do that instead.

my main reason for the tablet diy is to play my music folders... I make them every other week... with new content... then of course navigation (google)... web browser right in the car if im parked in a parking lot waiting for her to come back....and the other obvious extras n perks.... I think this is more for me than the pioneer... I was looking into that first.... and decided i wanted more hands on experience with a tablet and able to customize as well.... did you use a custom dash kit bezel... how about the wire harness what did you use.... Im thinking of just doing a simple aux wire from the top of the nexus to the aux input in an aftermarket radio

Hand ons experience using a tablet? I don't follow what you mean by this statement. I had the same expectations when I didn't have the tablet in the car. Android Auto looked so limiting. However I've had a change of heart after using a tablet in the car for about a year now and then trying out Android Auto for a week in a rental while I was on vacation two weeks ago. Hands down, the tablet route in the dash is not worth it. Its so much simpler and cleaner (both in looks and functions of the Android Auto unit) to install the Pioneer Android Auto unit I linked above. I'm going to go that route next summer.
I got used to the Backup Camera on the Android Auto HU and and I can't replicate that on the Tablet in the dash. You don't have to worry about the tablet being charged all the time so that you can actually use it in the car without having to take it out and charge it if you haven't driven your vehicle for a few days (perhaps this does not apply to you if your GS is a DD. Mine isn't and the battery drain on the tablet is a major PITA).

Yes, the audio shop custom fabricated the bezel kit and the wiring harness goes in the Kenwood HU that I already specified in my first post on this thread. I then connect the tablet via the OTG cable to a Digital Audio Converter to get better sound and then connect that to the HU AUX port - you can also see that in the pics I posted.

yea i checked it out.... and its great... I would just go with the nexus for now and see how my budget changes next year... for now I'm trying to stay under 200... do I have to get a dac/ microstreamer or can i just plug it from the 3.5mm headphone jack straight into my aftermarket radio aux input... what do you think?
So, did you switch, or are you now happy that you can run android auto straight from your tablet?
I am trying to find if Android Auto has any problems running from an Android headunit such as the Joying units. Otherwise, I would love to see if a nexus 9 could work in my Ram.
Having used tablets, android auto (pioneer and kenwood HU), and joying HU I think I can offer a lot of insight here.
For starters the tablet is still hands down the best carPC you can get. It simply does everything you want it to do without any sacrifices, and tends to look the most clean as well. The reflexive matte screens on android auto HU's are just dull and boring overall, but beyond that their performance is abysmal and android has been completely crippled on these devices in the name of safety. You cant reliably browse for music, the UI/search/scroll functions in the supported music apps block you from doing too much to keep your eyes on the road, and they all require you to plug your phone in which is just a PITA every time you get in your car.
I dont know about you but I dont like having a phone in my cup holder, glovebox, center console, or on some chintzy grip mounted to the dash. It's just ugly, the wires are ugly, and having an additional screen + wires dangling about just breaks the symmetry of a nice clean A/V setup. Using a tablet with hotspot is so much more elegant. The Nexus 7 will charge faster than it drains on any car accessory charging port (cigarette charger) so it should be nearly 100% all the time while you drive. If this car isnt your daily driver then why are you putting a tablet install in it? lol. Ultimately the Android Auto head units are manufactured by companies that just have no experience in this area and are prone to bugs and other anomalies. The entire experience just felt gimped.
As for Joying HU, while the concept is admirable the execution is flawed. Their biggest issue is just poor hardware. You just cannot squeeze an entire Android equipped OS with proper hardware and all the other stuff required to make a functional HU for the prices they are asking. If a tablet alone costs as much as their entire HU then imagine what kind of processor theyre sticking inside these things. While it worked overall, the dang thing has to BOOT UP every time you start your car. This might be tolerable on cold winter mornings where you might sit in your driveway for 5 minutes anyway, but for most other occasions it's just annoying not being able to get your music/waze configured until you've drive a couple of miles, or to just sit there aimlessly tapping your fingers waiting for it to start.
Also due to such poor hardware in the Joying units multi-tasking becomes a chore. CPU/GPU intensive apps like waze are laggy, multi-tasking between your music app is frustrating, and you forget doing things like split screen viewing. The only advantage these have is the ability to integrate with a backup camera, of which I have no need for since I know how to reverse my car without running over a fire hydrant.
A pioneer/kenwood HU might have superior audio internals, but you have to remember the source audio is usually coming from a streaming app which is going to be 128kbps or less anyway so youll never properly exploit all that great audio technology anyway. A simple 3.5mm to aux-in adapter works beautifully and produces good sound on any HU. I never bothered with DAC's or other ways to convert audio, just get a solid single-DIN HU and the aux-in will be fine for all but the purist audiophiles. Even among those types there is still no desire to use Android Auto since it feels like you're using a 1st gen smart phone from 2000.
Hi guys,
I'm working on a replacement for my Peugeot 508 multimedia&navigation unit because I need to implement new sensors & behavior, and I want also to use my phone Android Auto connected.
First of all, it consist on a 7 inches (or maybe more, if I find a way to rework the original housing with 3d printing) touchscreen (HDMI+USB) plus a brain and various proximity sensor (connected with various Arduino), 360 cameras & a CAN BUS bridge.
My first Idea was to use Raspberry Pi 3 with OpenAuto: it works with Android Auto (even with WiFi, that's mandatory for my project), but I know that maybe Raspi will got saturated.
My other Idea it's to use my old Laptop pc brain that's surely more powerful than Raspi.
But my doubts are:
1. is there an app that run on Windows (or Linux) that can be used to run Android Auto (client) supposing that my Phone will act as 'a server'?
2. Are there another low-cost brain solution that can help me reach my objective? PS: Android Auto radio can't be used here, because my 508 has different housing for touchscreen & 'brain'.
Thanks in advance at anyone that will reply.
PS: I don't know if this is the correct place for my post, but imho this seems the best place.
