Wizard generates noise when powered

Hi all!
I am using my Wizard in my BMW 1-series by hooking it to the AUX-port of the built in stereo. That way I can use it for TomTom, MP3's and phone, using the speakers of the car.

This works like a charm, but when I power the device using the cigarette lighter, it starts developing a lot of background noise. I can even hear the ESP computer kick in when I step on the gas to make the rear break out (rear-wheel drive rules!!!) It then generates a high-pitched tone.
I already routed power straight from the battery but this only made things worse. Appart from the noise already described, I then also hear the car's dynamo cause a noise that varies with the RPM of the engine.
I am starting to believe that this noise is standard when the Wizard is powered, but I would like to hear if you have similar experiences.
Thanks for your input!

Same problem
I have exactly the same issue in a Ford Mondeo...
Tried alsorts, filters, supressors... no joy. When plugged in, it gives 'noise' on the line in, which is a total pain in the butt!

So, this seems to be a typical Wizard issue...
To bad, since I thought I had re-invented the wheel.... Anyone have a clue as to what causes the problem. Could switching to a lower voltage or lower amperage perhaps solve the problem?
Thanks!
Stefan

I dunno...this issue is lot older than the Wizard and older than mobile phones, too. Lots of audio devices have had this problem with car or 120v home adaptors.
The simplest test is to try another adaptor, like a Targus. If that works, your adaptor is not filtering engine "noise" (electronic, not audio). Or it's not smoothing the electric current sufficiently. Since mine doesn't have this problem in either my car (M-B) or my truck (toy), I wonder about your adaptor/MDA.
Does it do it in other cars? Does it do it when using a 120v adaptor, or (better still) when you plug the car adaptor into a 120v to 12v converter?
One 2nd best solution would be to carry a second, charged battery, and recharge when you aren't using it as an MP3.
Curiously, nobody seems to have come up with a reverse A2DP Blue Tooth solution that allows you to beam your Hi-Fi sig to a receiver that pumps it into the AUX on a car, PC or home stereo system. I haven't tried using the B/T Stereo Headphone adaptor that came with my B/T phones to see if it can receive as well as broadcast (You use it with non-B/T devices so they can talk to your headphones--I use it at night when I don't want to wake the house but want to watch a loud movie).
Good Luck!

Sounds like your garden variety ground loop troubles.
I would do a quick search on google for 'ground loop' and see what comes up.

HP IPAQ 6828 speaker problem - solved

Hi,
As many of you know that the HP 6828 has a problem with its headphone socket. It happens that after you remove the headphone from the headphone socket there is no sound from the speakers. The phone works O.K with the headphone and the phone THINKS that the headphone is still connected even you remove it from the socket.
The problem is with the headphone socket. So, if you are lucky enough and still have warranty - you run to HP and get it fixed. But for others like me whose phone is out of warranty running to HP is not feasible because HP does not service at the component level - they will just replace the whole motherboard at an astronomical price.
So, if you can get the headphone socket you can get it replaced locally. You can get it from here:
http://www.repairhppda.com/product_...d=539&osCsid=d8ce9e2f4d8702b3e00489f6689cd8fc
But if you are a bit enthusiastic and have some DIY skill you can fix it yourself as I have done it:

There are six contacts on the headphone socket. three on left and tree on right.
If you short the upper two contacts of the right side your phone speaker will start to work again - but you can not use the headphones even if you insert it - it will not work. So if you don't use the headphones this is the solution for you. Just solder a small piece of wire between the two contact points - and voila.
But is you want to use the headphones too - there is a workaround too. You attach a small piece of wire to right top most contact and another one to middle contact on the left side as I've done in the picture. Now if you touch these two wires momentarily once your speaker will start to work - and again if you touch these wire and insert the headphone - the headphone will start to work. This will act as a toggle switch. You bring out the wire from the backside of the battery and keep it between the battery and the battery cover. You set your phone to use the speaker normally - and when you need to use headphone just open the back cover and use the "Switch". After you finish hearing music or radio - open the back cover and use the "switch" again.
So this is a no cost solution to the speaker problem. Although, it is better to get the headphone socket replaced. I ordered mine and it will take about 20 days to arrive. So till that time - long live DIY

[Q] Microphones?

Anyone know of a microphone that I could just plug into the audio port and leave there or anything? Does it support audio input through the mic jack?
The recorded audio on the Iconia is completely awful and useless.

Where's the mic jack? All I have ever seen is the headphone jack, USB, HDMI and charging ports.

Yes it does support audio input through the headphone jack. The internal mic is so bad it's practically impossible to do a video chat. I used a psp headset I had lying around, works like a charm for gchat/skype.

Really? I tried plugging in a standard headset that works on my Acer laptop and it certainly cut off the internal mic but sadly no sound from the headset mic.

The 4 section headset comes standard with most of today's smartphones.
I have tried the headset that came with the Iphone 3GS and the Blackberry and they both worked on the A500 for making calls over Skype. The sound quality from the Blackberry headset was much better that the one from Apple.
But, I did notice that the internal mic produced better results when using the recorder function.
Probably need to adjust the mic level on the external headset, but I could not find the setting to adjust this. When pressing the volume button on the A500, a set of slider bars would appear - sometimes there would be a setting for the mic, but more often this would be missing.
Can someone shed some light on how to get the mic slider bar to show up. Thanks.

Dug out the headset that came with my Nexus One and it worked! Couldn't see a volume control for the mic though,just the three standard ones.

Almost all headset with mic will work on A500, just ebay it

can anyone else confirm the iphone headset works?
the mic on my iphone headset doesn't work at all in the A500. it works in the iphone so i know its not faulty.
i then tried an "urban ears" set and the mic works perfectly so i know its not my A500.

Wired headsets in which the button works?

Ive just accidentally broken the headsets that came with the phone, and now Im looking for another headset.
The problem with our phone is that the pinout (the mic and ground pins) is inverted in comparison to samsung, LG, HTC etc ). Therefore, we cant buy just about any headset. Also, I want a wired headset (not a wireless one).
Is anyone using a wired headset in which the button works? I want to be able to take and drop calls, and long press to skip track (which would work if taking and dropping calls works).

Yes, I'm using Jabra Chill headset (got it new for 10€), the pins on the jack are the same as original Huawei headset. Also I'm using Headset Button app, that can emulate multi button headset, so I can skip tracks, forward/reverse songs, etc.

Thanks for the info. Just needed to know one more thing. Does the mic work as well? Can you use the button to receive calls? Also, do you have a u8800 or one of the variants? Is there any difference in the pinout for the u8800 and the variants?

Mine phone is U8800, my brother has U8800 pro. Both phones have same pinout. The microphone and the button is also working. If you are using the Aurora rom, you should also tick "use headset microphone" in sound settings.

Do you know a headset like the one you pointed but in-ear?
Those are better at isolating the ambient sound.

Ive ordered one. Lets hope it works out when it is delivered. Thanks for the help Schrauff.

Maybe these? http://www.jabra.com/sites/mobile/na-us/products/pages/jabrarhythm.aspx?tab=support#UID6
I haven't tried them out, but they have 4-pin 3,5mm jack and mic+button.

I'm also found the a-JAYS One+ which is a great looking headsets with a flat tangle-free cable and has a mic+button.
Here's a nice review: http://www.androidpolice.com/2012/0...and-performance-without-a-hit-to-your-wallet/

Anyone tried one and can confirm that the button works?

Just got the Sony Ericsson MH-650. In ear, perfect noise isolation and the button works quite well. Awesome sound quality as well. Thumping bass and crystal clear trebles
Totally recommended for everyone. At Rs. 1500 (do your conversions, I'm too lazy), theyre really nice.

Just bought a Novero Brooklyn Wired Stereo Headset with Mic http://www.novero.com/collections/music-headsets/brooklyn.html but it turns out that it's not compatibly.
I listen only one channel on both phones and when I click the button I listen regular stereo.
They seem to be great headphones, but not compatible with our 8800.
Crap
Found this life-saver converter:
Adapter Pinout: T-T, R1-R1, R2-S, S-R2

It switches the Ring2 with the Sleeve.
Probably there are more cheaper version on ebay/dealexterme.
Apparently our phone has Sony Ericsson Xperia compatible pinouts, not iPhone compatible.

Help On Fixing Headphones

So I'm using the Samsung earphones(The ones with the flat cable. Model HS330) that came with my Galaxy S4. These were a good set of earphone but then, the plug is messed up.
Audio tends to only come from one side or no sound at all but I can get it to work when I mess around with the cable near the plug.
Eventually the cable decides to give up and messing around with the cable doesn't work anymore.
I need help from you all to get this fix sorted out.

These are the earphones I'm working on.
So I'm trying to get the earphones fixed by replacing the plug with a spare headphone plug I have laying around. These Samsung earphones are really good compared to the cheap ones and quite expensive if you want to buy a new set.
These are the headphone cable I have. It is a TRS plug(2 rings on the connector. Common on most PC earphones) unlike the Samsung's which is TRRS(3 rings.This type is common on earphones with a microphone.Basiclly any earphones that comes with a phone). Using this means the microphone and volume control on the earphone won't be wired up.
I stripped the cable on this one and there are 3 wires to deal with. The red and green I marked out are the Left and Right audio. The copper wire is ground.
As I said, I can't wire up the mic and volume controls with this cable but I don't really care about this part because I'm using these earphones on my PC most of the time. I just need L,R and Ground
I chopped off the cable on the Samsung earphones and stripped it to reveal the wires. This is what it get. All three wires are actually wrapped with these copper things but at this point I'm confused with is L,R audio and Ground. I need to find these 3 wires to wire up to the cable I have.
If I sorted out the wiring, I can solder them all in place and done. But I need help.
Anyone who can help me sort out the wiring of these Samsung earphones with be appreciated.
Regards.
