DIY AUX unit with steering wheel controls

On my previous car, I hacked together an aux input with two CD-ROM plugs as described in many places on the Internet (here's one). I was really happy with it, and fully intend to do the same on my new (?) second-hand car, which also has CD-changer support, but no AUX. (Neither car had a CD changer installed, because I couldn't be bothered). The new car has steering wheel controls though, and I thought this could be a nice upgrade, but I'm really not sure how to do it. The pin-out diagrams for the CD changer plug (which I stole from here) for the CN702 12 pin connector shows lines 9 and 10 as TX signal lines. Since there are track (and disc) up and down buttons on the radio, I assume this is how the commands get through to the CD changer. And the phone obviously has support for headsets with track skip buttons. So the stars seem to align. Except for the details.  First, a normal audio cable only has three wires and one with headset controls have four: Ground, left, right and comms. I think I can connect the following pins on the 12 pin connector to ground: 6, 7 and 9 and then 1, 2 and 10 get connected to the correct wires. Is this correct? Second, I have no idea if the actual signals sent to TX for a CD changer bear any resemblance to what the phone expects from a headset. Does anyone know? I can probably hack a test using a bread board. I think. Third: I really only dabble in these things. Did I miss anything really important?

Turn laptop speakers into aux speakers

My laptop just died and I took it apart. The speakers have a 4-pin connector, which I would like to splice into aux and power to make an aux enabled speaker I can use. How do I do this? Pics: Thanks and RIP laptop. A little eulogy, because why not: Dear laptop, you will be missed. I had you for 5 years and you were a great machine. I took you apart and put you back together. We had a great time together and you lived a long life. I hope you have a great afterlife as a set of speakers, external monitor, hand warmer, and many more projects. You will be missed.

Stereo Stolen!

My car stereo was recently stolen.. Bummer. Here is my idea; I am tired of putting stereos in my car only to have them stolen. I don't want to buy another CD player w/ an aux in input for my mp3 player, since I don't really play cd's anyways. What I want to do is install just an aux input line to my car speakers and mount that easily in the empty hole. Is that possible? Do you somehow need to power the speakers? How do you go about doing that w/out buying a new stereo? My main goal is 1)to put something there that will run the sound from the MP3 player 2)not need a stereo to do it. 3)do this so no one would think it is something they could steal and profit from. HELP! :)

Make easy portable speakers with battery and aux cord/port

Long story short, I want to make a costume for a LARP with built-in speakers. I am both a busy and a lazy man, so I want to find the simplest way possible to make this happen.  The idea is to connect my two 4Ω, 5W speakers together with a battery and a aux port. What I need to know is what kind of battery (preferably rechargeable) is best suited for this endeavour, how to connect it properly with the essential components and how to connect an aux port/cable, making it possible to connect any audio device of my choosing.

How can I connect my old stereo speakers to a computer/iPod? Answered

I own an old Panasonic "CD Stereo System SA PM-21". I got it a few years ago, so it is not the newest, and unfortunately I can only listen to CDs, cassettes, or the radio. The speakers are really good however, so I'm not ready to simply give the whole stereo away. So my question is, how can I connect a computer or iPod to these speakers? They have two pairs of cables each as you can see below. Somebody already suggested using an FM transmitter or cassette tape adapter, but those options would probably give me much less quality than I would get if I connected directly. Would I need some sort of amplifier or converter? Is it possible? Thanks in advance for any help.

'02 Prius: Create AUX audio input

My Prius is still cruising along fine. But, I tire of messing around with FM transmitters to get my audio into the radio/audio system. I purchased mine with a 6 CD changer, so I know there's a way to add audio in. [The changer died after 2.5 years: Toyota said $300 to send it off to CA and get someone else's refurbished device back. No thanks.]I see all the newer cars with an AUX audio input jack. I'd like to put in such and/or a Bluetooth input.I went to a local car audio store and they said $450 to add it in. Bleah!Anyone done this or know how? [This is the original body style, not the newer, fastback style.]

Use a Prius as Aux. A/C Power Generator

We saw a story about someone that claims to have hooked up their Prius' electric motor batteries, through a AC Converter of some type, that converts the 200+ DC volts in the Prius main batteries into 240 (or 110?) AC power that can be feed into your house. See the following URL: it here vs. having someone really "tell all" about doing this for real, including the sources for the converters, etc. is what is missing. We have occasional power outages and our house gets cold in Washington State. Using our Prius' ability to self-regulate it's batteries seems like a great idea on getting more value out of this car.Come on your tinkering experts.... show us how to really do this.Rick

Anyone got any insights on this for a DIY car bluetooth system?

Hello, I'm hoping to build a DIY bluetooth music adapter with the ability to also answer calls and provide a microphone on board instead of using the phone. I found this:;=282112739276#ht_10252wt_1397 It looks like it would meet all the requirements I need - It has AUX in for non bluetooth devices, bluetooth for phone calls and streaming, A microphone, Media controls and even an amp and should be able to be wired in to the cars' 12v power output. I am concerned that I am overlooking something obvious... I know that the the media controls might only work over bluetooth and not over AUX...but thats not too much of an issue is suppose...Does anyone have any more information on it?

Need advice for adding aux-in/line-in to Philips AE2160/00-A AM/MW/LW portable radio

Hey there, this is my first post! :) I'm from Germany, so please excuse my grammar! :D The reason why I'm opening up this new topic is, I didn't find any instructable or guide on how to add an aux-in/line-in to my simple mono AM/MW/LW radio Philips AE2160/00-A. There's not much to find out about the technical specifications besides the standard product information: Tuner • Analogue tuning • Wave ranges FM 87.5 - 108 MHz MW 525 - 1606.5 kHz /04 LW 150 -255 kHz /00c FM/MW /04 FM/MW/LW /05 FM/MW/LW • Ferroceptor for MW (and LW) • Telescopic aerial for FM (and SW) Amplifier • Max. output power 300 mW RMS • Tone control Music /News Sound system • Loud speaker 100 mm • Metal grill Power supply • External supply /00c, /04 230V /05 240V AC • Batteries 2 x 1.5V , type R20/D cell/UM1 Connections • Headphone socket 3.5mm General • Material Polystyrene, metal grill • Weight (g) 520 • Dimensions (mm) 210 W x 150H Here's a link to a photo of the device:;=2000&$jpglarge$ I didn't even find schematics/circuit diagrams for this or a similar device. There are lots of tutorials on how to add such an input to a car radio or a boombox/stereo cassette player a.s.o., but not for a simple AM/MW/LW radio. My questions are: 1.) Are there any similar hack projects here in the step-by-step or forum section? 2.) How do I find the right connector or place to solder a 2-way-switch between the sections (tuner, amp, speaker)? After the hacking job, it should be possible to switch between normal radio listening mode and aux-in/line-in mode from an external mp3 player, notebook, a.s.o.. 3.) Is there anything else to know for this project? Yesterday I've opened up the case for the first time and looked over the circuit board and the connections. I had no cam to take pictures, but I try to take some mobile phone cam pictures of the circuitry and parts at the next opportunity! Cheers, arok1

Either fix, or buy new one? Answered

Hello! Just a regular question or help passing by. So i have this set of wireless headphones, for two years or so. ( Philips shc8535/10 ) and few months ago, one side of the heaphones stoped working. i jus thear some rambling, and screatching noises. I took them apart (Warranty is obviuosly gone), and found out that the Auxillary plug ( IN ) has it's contacts bent. You could probbably tell by the pictures i'll attach somehow. Sadly, the part doesn't have any index number on it or anything, so i can't just order it 1-2-3.  Question is, can i fix it? i mean, i can't easily take it apart, it's plastic, and it's probbably molded in it ( the contacts), i've tried bending them, but all i get is either more or less rambling noise. And other part of the question - order it online, is that possible?

Trying to create my own car head unit.. Sorta.

So i enjoy electronics, so i thought of an idea that would really benefit my life. I enjoy listening to music in the car. Like really enjoy it. Currently i have the original head unit that came with the ford focus mk1. Its terrible, and the speakers distort at loud volumes. Plus there is no way currently for me to listen to my own music apart from a CD. Which come on.. no one uses anymore.So here's my idea that im finding difficult to bring to light. I was hoping i could create some sort of botch head unit. But i want to create this using components that are not end products. So no i do not want a £100+ amp that does this for me without the DIY. It should be a lot cheaper to do this DIY.So my idea was 1 amplifier circuit board, which is difficult to find to power 4, 4 Ohm speakers. So my idea was to have 4 separate amplifiers for each speaker. I can't find a single channel amplifier to power a 4 Ohm speaker however. The signal the amplifiers would receive would be through an auxiliary cable or bluetooth reciever.Any ideas to point me in the right direction would be awesome. If there's a loophole in my idea then please let me know. Still a lot to learn, but that's what were here for right.Thanks in advance.

How would I go about building a portable battery power boom box with 2 tweeters and one large woofer.

Over the Christmas holiday I would like to utilize two tweeters that I obtained from computer speakers and a subwoofer that I obtained from a surround sound system to use in a portable battery powered boom box.  The goal is to makee the whole setup rechargeable (thought about solar panels also, but baby steps) with a usb slot (power only) to charge ipods/iphones and a single aux cable.  I have been experimenting with each of the speakers and I have an idea of what size of box I am going to have to produce the best sound, tips on this would be welcomed as well.  Strong deep bass is a major goal of the boom box as well.  Physical volume controls are not need.  The only button I assume would be for the power. Any tips or suggestions are welcomed.

I have a record player with a broken cassette deck, I want to add an aux port. Answered

I have an older Prolectrix record player with CD and cassette. The amp itself seems to incorporate the cd and radio. The cassette seems to cut into the amplifier circuit when one is inserted into the deck via a micro switch.   I have managed to remove the cassette module with all it's wiring, it was plugged straight into the board via a header plug. I was considering using a module such as this, as it would fit in the existing hole quite nicely. I haven't tested voltages as yet. 3.5mm is fine, or stereo phono is also usable. I need some advice as to which wires I can use as an input. Obviously there are two power wires to the motor. The microswitch has 3 wires, red, black and yellow, then you have the three more going to the play head. Any ideas please? My electronics knowledge is quite basic. Here's a picture of the turntable in case you know it.
