    55One part of the project is of course the CarPC. CarPC is acting here as a multimedia system controlling MP3 and video playing. It does also support internet radio and all that nice stuff one can do with PCs :) So on this page I am presenting the used hardware and some statistics incl. pictures.

    7 OpenBM's left button field do control the BMW radio without need of a CarPC. Yeah, it do this by emulating a MID device. The right button field is for the control of a CarPC. Whenever one push, release or hold a button, a message is sent over the IBus. The [wiki:Software/Gateway IBus/D-Bus Gateway] is receiving that messages over the wire and sent it as a key-code to the system. So it does emulate just a usual keyboard, so actually very few of those keys.

    2626The full power consumption of the system incl. TFT is around 3A when playing MP3. So, I think the M2-ATX is more than enough for that. The boot time is around 20sec, which is pretty good. The boot time is still not optimized, and I hope to push it down to at least 15sec. 10sec will be the ultimate goal, but I doubt that it will be possible.

     31== Installation/Mounting == 
     32For the installation of the CarPC I choosed the place in the trunk. The CarPC was mounted using special rubber-screws as widely used in LPG (liqued propane gas) installations. This bolts allows reduces vibrations and are perfectly suited for a CarPC. Although I am using a SSD and do not have any rotary components except of the cooling fans, I think reducing the vibrations would not make it worse :)
