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

    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.

    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
