Suggestion to devs: audio to IR adapter + remote control app - Android Software/Hacking General [Developers Only]

I cant program, simply to dumb to learn it, but i had a idea that i think is worth spreading
Use the audio output jack, connected to a IR diode and write a app that uses audio bursts to control a ir reciever (tv, stereo and so on).
I dont know enough about the ir diodes to be able to tell how it should be wired together, but i figure a simple stereo plug, a resistor or two and a diode on top should suffice, and make the ir pulse by the audio signal pulses.
the audio output should be fast enough to transmit directly to the diode, if the voltage and signal strength is within ir specs.
So what do you (more tech skilled) guys think?
is it possible?
my android phone (htc hero) can do everything exept brew a decent cup of coffe and remote control my home media center, exept my xbox media center over wlan.
So a ir remote solution is the single most wanted feature that i dont have..
i figure my coffe maker is good enough for the time being..
edit..
i found a proof of concept, someone actually made this and got it to work on old nokia phones using a wav sound file, that he sampled using audio input on his computer.
http://jumpjack.wordpress.com/2008/06/10/turn-your-phone-into-an-universal-remote-control/
i would suggest that a ir sensor should be involved in the hardware, so the end user can program the buttons himself in the app.

Using phone as a Bluetooth Headset/Speakerphone for PS3

Hey guys, Is there any type of app out there that lets your phone act as a Bluetooth headset??? I mean by use the phone for my PS3 As a Mic. Is that possible????? Please let me know!! THANKS! Im on Windows Mobile.. On a Kaiser.
I would love a similar application for few reasons:
. No other headset to charge, pretty cool i must admit
. you can use a normal 3.5mm jack, 4-pin mic you usually get with some mobile phones to have working ps3 BT headset
. . you could use normal headphones for listening to video/audio on pc or PS3 without a cord going to the computer/ps3 [but no mic on ps3 during lan play]
. for those wanting a bluetooth throat microphone made from scratch, you don't need to hack a a2dp bluetooth handsfree kit, just to make a 3.5" 4-ping plug + adapter [or your phone plug]
You can actually achieve more or less similar with an a2dp bluetooth small handsfree kit... I actually wrote a piece on what i want to achieve here [throat microphone, talking about bone conduction a bit]:
http://www.dealextreme.com/forums/Forums.dx/Forum.-206~threadid.209744
In the end, you need an hacked rom to overcome the bluetooth stack limitation of some handsets if any, and a program that act as handset server profile.
BlueputDroid would be the best contender for this jobs, as it allready pose as bluetooth server profile... [http://forum.xda-developers.com/showthread.php?t=940511&page=21]
That's what I need

Did you find any solution?
Bump. This would be awesome!
this would be amazing
I really need something like this now!
any solution found?
I heard its simple to make your own app for this... if only I had the knowledge of an app developer.

What is the best car head unit for use with the SGS i9000?

I am looking for a car stereo with the following features for use with my Samsung Galaxy S i9000 phone. Most of these via bluetooth of course.
- navigate through and select tunes, podcasts, and audiobooks
- stream audio
- Display caller id and allow me to answer the call or ignore it
- bluetooth hands free calling
- associate with my phone when I start the car so I don't have to pull it out of my pocket
- pause the audio when there is an incoming call or I place a call via the stereo
- be able to place calls using the address book in the phone
Can all of this be found in one unit? Am I hoping for too much?

mine is a bit old but it's amazing Clarion CZ509
http://www.clarion.com/us/en/produc.../cd/CZ509/us-en-product-pf_1172409026831.html
does all of the above and more
Have you tested this with an i9000 or at least similar?
How does it work with your audio library?
Sent from my GT-I9000 using XDA App
using my deck, you can control the phone audio/video stream, and vice versa, as in you can also use your touch screen to control the audio/video as you would normally do, and the car plays the sound.
the remote control works as well, i barely use my remote control as i seat a arms/finger length distance of the deck controls
it uses the standard A2DP Bluetooth controls, it's very natural.
another ability of the deck i'm using in my car, it lets you choose USB, so you can actually hookup the usb/charger wire from the SGS i9000 to the car USB, and it will both play and charge your phone!
this will save your phone battery (bluetooth sucks up a lot of power) so you will only use the bluetooth to talk for incoming/outgoing calls
you just touch a button on the deck to start talking, you can also dial from the deck, but is faster to use the phone to dial.
when you have the phone connected via USB to the deck, you wont be able to use the bluetooh A2DP to control the playback, but you still have the deck controls and the remote control that comes with the deck.
go to the website and read the PDF manual for more details, all i can say is i'm extremely happy and sastified with this setup
you can also just use a regular USB stick to play audios from the deck.
I don't even carry CDs in my car anymore, I loaded my entire music library in a 32GB USB stick, or use my phone to play audio, my phone usually will have the latest song i download from the net, as i always forget to update my USB stick with the latest songs
This is what I am using, and I get full features from mine.
Music controls on handset or deck both work (and remote).
Caller ID/Missed Call/Call log scrollable menu on deck screen.
BT phone audio through speakers with included in car mic.
Full audio volume control.
Charging from USB port (with regular USB cable, some companies like Alpine you need their specific cable) and thumb drive play capability.
3.5 aux jack

Shoot. I was || this close to getting the Clarion CZ509 but I only found it at 2001 Audio/Video and I don't like those guys much. Instead, I just had the Sony MEX-BT3800U unit installed. I've only started playing with it but I understand it has the same capabilities of the Clarion and a great interface on the deck face.
FH-P8000BT; Voice Dial
Has someone tried the Pioneer FH-P8000BT? I uderstand it's a nice option but don't know if it works ok with Galaxy S's.
Also, is any of the head units mentioned above able to dial by voice? Is it functional?
Help with CZ509
Hi AllGamer,
I tried to send you a PM but I'm not sure if it worked as it's not sitting in my outbox (perhaps there's a post count limit before we can PM).
Anyway, I'm hoping you can help me out. Here's essentially what I said in the PM:
I noticed that you have gotten most everything to work with your clarion cz509 HU. I too have the same HU in my car but I can not get the functionalities to work properly. I used to have an LG voyager and while it did not do ANYTHING except bluetooth, it did do that well. It did not do phonebook or streaming audio but the BT would pair automatically every time I got into the car.
I now own a Samsung Fascinate (Verizon) and I can't even get the BT functionality to work properly. I can get it to pair (and once paired it works fine) but it does not seem to auto pair when I return to the car. I also can not seem to get any of the other functions to work. I realize it's a bit different than your handset but my questions to you are:
1. Is there something setting-wise that I need to change on the actual HU itself?
2. Is there anything to do with settings on the phone that I need to look into?
3. I can't even get it to do audio through USB. Is there something I need to do (on the phone end) to get this to work properly?
I would be satisified with JUST the bluetooth working and auto pairing when I get into the car. I don't need the phonebook or the streaming audio or even the music via USB (I can just use my iPod) but I would like the BT to work at least. The engrish manual that came with the CZ509 is less than helpful.
I'm hoping you may be able to provide some insight.
Thanks!

[Q] Ryzmedia IR device universal remote dev???

Anyone hear if there's any development going on for use with the Ryzmedia IR device?? I'd find it much more useful on my Eris than my itouch. Here's the link to the device webpage, and some technical information that might be helpful:
ryzmedia (dot) com
compendiumarcana (dot) com/iraudio/
From MobileCrunch:
You could go to Radio Shack right now and build one for $5. $10 is very fair, especially for the time and love put into it.
Basically what it is is two IR led’s connected to the right and left polarities of the headphone plug. Those LED’s are actually flipped opposing each other. This is needed because the standard headphone output only does 0-20k per channel and the normal IR remote operates at 38k. By putting one side to each of the functional channels and having that built in modulation gives you the ability to generate a 40k signal.
So how you do it is:
1: Record the IR behavior using a IR detector connected to the ground-single channel at as high of bit rate as possible (usually just 41k or 48k on a normal lappy – may be up to 192k)
2. Clean signal to get pure digital square wave
3. Reassign the signal to play back at 19k on a single channel
4. Invert that same single channel and assign that to the other channel
5. When played through your headphone port using the appropriate equipment it will show up out of the LED’s as a properly modulated 38k signal just PERFECT for controlling your TV!
I made a learning version that basically had a 4-pole plug and used the Mic port for the IR detector. The hard part is in getting the signal, turning it to 1/0′s, changing to 19k, and running inverted signals on each channel. I haven’t actually gotten that far and made it to test some things, but recording off the mic port does seem to be good enough to clean up on a PC and have it work. Though hope that the App Makr for Android will at least help me get an actual interface instead of a playlist….
Got any android audio experts in the house?

Music control on phone for Car radio

Hello,
I have really no idea if this is possible, how hard this could be to do and what it can require but :
1 - Would it be possible when I plug my phone on my car radio with USB to control the music with my phone instead of the radio itself ?
2 - Would it be possible to deport the sounds (calls, applications etc) on the car speakers ?
Let me know if I'm not very clear
PS : please don't answer something like "use a jack-jack cable"
Thanks !
From what I get, you want to "stream" audio through the USB port. I don't know why would you want that and the jack-jack cable is not good (maybe you have a USB port on you car stereo but no line in) but as far as I know it would take A lot of modifications (stereo and phone) to make it work.
So, theoretically it is possible, practically I don't think someone will ever make it possible.
Im pretty sure it would be impossible to control the car radio with the phone via usb. There might be some kind of solution using IR, but I don't know how that'd interface with the Droid. Most aftermarket decks allow for a wired remote on the back (looks like a headphone Jack). I've used it with a steering wheel interface adapter and it worked well, so there is a possibility that a custom usb cable could be made, but would also require a custom app written for the Droid to output the signals through the usb.
On streaming radio via usb, I don't think that's possible either, bc the uusb on the deck is looking for files to read on a mounted drive.
If you happen to have an incredible, you can get the tv-out cable and make a shorting pin on the video output. This makes the phone think it's connected to a TV, and will then stream Pandora, music, Google navigation, etc through the usb. If you do this with your aftermarket radio, you'll need an aux input and an rca to 3.5mm cable unless you already have RCA.
Hope this helps!
Thank you for answers! I was asking that because I remember when I had an iPhone, I was able to play, pause, forward the music from my iPhone. I will try to use the aux-in (I have a little Pioneer DEH-3200UB).
Thank again !
That's because both the head unit and the iPhone know a common language and communicate.
Sadly, I don't think there's anything like that outside Apple.
It is called Ipod ready. That could be emulated in Android, would be another bite out of the apple,s ass.

What is a 'WWW' MCU? Anyone using USB Audio?

Hi,
I run a car audio firm, we have a PX5-based unit a client ordered.. The MCU version is "MTCD_WWW_V2.54b_2" .. Our goal is USB audio working proper, among a few other things (better interface if possible, better apps, better SQ stuff)
I haven't seen a "www" mcu anywhere? It's sold as an EONON GA7150A..
Anyone know anything about this MCU? If it's compatible with any others or anything like that? I definitely would like to root it, update the ROM to something better, get rid of the "Windows Mobile" part of it which was, IIRC, advertised as the ability to 'boot' between Android and Windows but is actually just a different interface theme from the home screen.. Also want to do whatever we can for sound quality and smooth experience.
I should note that, as a car audio company (in Canada), we are seriously considering producing our own Android units.. likely 'producing' would consist of getting units like a px5, branding them and primarily, having a SOLID software system built for automotive use. I think a lot of these units are a great start and are ALMOST there for a lot of things but..some of the interface stuff is rushed, not translated great, etc.
What I'd like to see is an Android unit, priced like these ones usually are, but with *really* good class A interfaces. The kind of experience you'd expect on a Samsung phone or a Pioneer headunit. I personally have been using my Samsung Tab S 8.4" in my car as my 'head unit' (paired with a Pioneer single din for a hardware volume knob and some easy control) for along time and I would not want to ever go back.
Here's a short video of the interface and version info..
My eventual goal is getting USB audio working decently. It does work for most Android apps but the volume control only controls the internal audio chip, and the radio app routes through the internal audio chip as well.. I assume perhaps other sources like DVD and line-in would as well, I haven't verified but I will pretty quick here. I plan on making another video showing what works/what doesn't/how it works.
I'm hoping for a software only solution but am happy to hack the hardware if needed. I'm using a Behringer UCA-222 as a "DAC" (same as 202 but red in color) but won't actually be using the DAC in it but only it's optical output into an Audison Bit 8.9 DSP/Amplifier.
There's the possibility of routing the px5's audio output RCA's to the Behringer's Input and 'monitoring' that input to the optical output via software but that doesn't solve the fact the volume control does nothing for apps when using the USB.. Eg, youtube plays through USB/optical fine but volume control doesn't change the volume..Radio plays through the px5's audio chip and volume control controls that, and shows on screen.. I could force everything to play thru the px5 audio chip and then monitor it to optical but that defeats the purpose of what I'm trying to do completely (full digital audio to the amplifier).
I'm willing to sacrifice some sources re-routed like that though, eg, the radio would be fine as it already sounds ****. Aux in also doesn't sound great usually and won't be used in this car anyway. DVD would be nice to have optical out as well but
I'm currently still searching for a schematic/block diagram for these devices, this would probably answer a lot of my questions like.. I'm curious whether audio from any of the other onboard devices (radio, dvd, aux in) go through Android at all or whether they're directly sourced to the output chip.
If it's the latter - that sucks - but I wouldn't be surprised. I have read the thread about the hardware hack to allow android control of the audio chip but I don't see this giving me the functionality I need. If it is wired like this, and I can get the other components (eg. radio chip) to output their audio to Android, digitally somehow and have Android push it to the USB audio device that'd be cool.
Is no one else using a USB dac on any of these units? I have many years experience coding, hacking, electronic engineering, tinkering, etc. including Android but I haven't done many of these Android Head Units.. A lot of times we use tablets instead! But this client wanted OEM look..so we thought we'd give it a shot.
The difference between the audio quality from the internal DAC and the USB audio device's optical routed directly to the DSP (digital to the power amp) is definitely noticeable, even with there being very little noise picked up in our interconnects.

tha same question (#1956) i read in this thread https://forum.xda-developers.com/an...-head-unit-discussion-thread-t3573881/page196
it should be KLD (klyde), you can read the answer in post #1959
Thanks for the pointer.
Hi,
I uses the newsmy carpad since 2 yrs with android box with wince interface and same issue of radio, bt and dvd being analog while the android side of things is 100% digital output via the included hdmi.
I put aside my alpine pxa-h900 and installed the helix dsp pro with auto switching of input with priority on digital input and use internet radio apps, android bt apps and plugged in an usb portable drive for dvd/cd.
Cheers.
