I have made an interface car's media-buttons on steering wheel

AlCapone · 06-19-2006, 12:46 PM

I have just made me an USB-interface to the cars original media-buttons on the steering wheel.

This is a generic A/D interface that can read *two* analog channels, and send unique codes for different resistance.

Most cars, and many aftermarket "remotes" for car stereo's (Pioneer/Sony+++) will work with this device, as well as my Xantia.
It even supports two-channels (some cars need that)

Besides interfacing steering wheel, it will also send codes for "Ignition on" , "Ignition Off" , "battery below (preset) threshold" , and "battery voltage retured to ok"

So, who is interested in buying such device?.. if I would start to produce and sell them. ?

(This device connects to the wires that normally connect to the stereo - resistive input)

A few months ago I would have purchased one of these off you in a flash, but I have been playing around with the Phidget 8/8/8 interface kit, and it does all your interface does and more. The phidget is a little more pricey, but has the added bonus of various source code examples and a library for coding your own apps for it.

If you could add all the features of the phidget for a cheaper price, I'm sure you would have a very popular product.

How many steering wheel buttons can your device handle

about 31+31 , (two channels), it also depends on the values and the resistors.

AlCapone, is there any way you could send me the pinout of the citroen resistor system ? i have been trying to do this for a while now but no-one can tell me which pins are the actual resistors in the little iso plug.

Nice, i'm interested. Can i replace the ignition wire with the dimmer wire so my computer knows when my headlights are on?

Kalt · 06-20-2006, 07:52 AM

Would it be possible to implement more lines that send code when voltage is recieve like the ignition line?

Yes.
I will make pictures and place them on my site with the product.

Sure, that's possible, I can also add an extra input for "custom" functions like this.

Awesome, i think other members would also be interested in a device like this. Would you consider developing a plugin for girder 3.3

Thanks, much appreciated. is your site the madhacker one ?

Bonus: it alredy works in Girder 3.3 , and 4 ... whithout a driver ! - it is a HID device .... no buggy drivers necesary !

will explain more on mu site.

This device is gonna free up couple of my usb and serial ports, i cant wait to get my hands on it. Keep us up to date with you progress.

I will, I will make a webpage about it with all details and option to buy it
(ETA: next week.)
