iBug Logitech Microphone Install (pics)
I've been working on trying to use voice control in my car for quite some time. Because of the location of my touchscreen, it's not completely natural to use it and I find it a distraction when driving.
I also think that controlling the computer by voice is super cool. When it works properly, it's like magic and you can drive and operate the computer easily.
So I :search: around these boards and have been collecting info on NaviVoice and microphones and voice training and such to try and figure out how to integrate this into the car. 0l33l gave me the idea of putting it in the header and I tried the logitech out in a variety of places before deciding that he was right, the header is a good spot for it. It's close to your mouth and if it has trouble hearing you, you simply tilt your head upward a bit and you can usually compensate for whatever noise is going on.
First, I purchased a noise cancelling microphone. I was told that this worked best and I haven't been disappointed by the Logitech desktop microphonehttp://www.logitech.com/lang/images/0/3953.jpg. It was about $30. I got the analog version rather than the USB version partly because there is supposedly a small PC board in the base of the mike that I didn't want to have to deal with and partly because I didn't want to use up the bandwidth on the USB line. Besides, the microphone input on my Epia M10000 was open and I figured I wouldn't have to worry about whether it was drawing power when the car was off or not.
First step was to open up the case. It was incredibly simple with just the microphone element and the mute switch.
Next, carefully remove the pieces which were held in by hot glue. The only thing to be careful of here is not to cut the wires by accident (I was using an Xacto knife) and to be sure all pieces are free and clear so you don't accidentally break a wire.
Next, where to mount it? In the Beetle, there is a handy sunglasses holder that looked like a likely location. I drilled a hole pattern in the end closest to my face and cut away the foam padding on the inside to provide a place to mount the microphone element.
I hot glued all the pieces into the holder and made the mute switch accessible, which turns out to be handy. I use FrodoSatX and you get feedback from it if you have a microphone plugged in. You can actually hear yourself saying the commands over the car speakers and the road rumble, too. It also introduces crackling noises into the sound. Turn the mute switch on and you're good to go.
That was all there was to it! I ran the wire inside the ceiling trim to the back of the car where the computer is located (it comes with about a 10 foot cord) and plugged it into the carputer. To my surprise, it worked on the first try.
