Double DIN LCD, and other questions (sanity check)
I've been toying with the idea of an in-car computer for years, great to find this place and also great to see that people build things like in-car PSUs to save me some effort.
My car is a mixed blessing as it provides me with a Triple DIN in the centre console which gives me tons of room, it's also a curse as I don't want to lose space in the glove box or under the seat, so everything is going into this space.
I've measured up the double-DIN kenwood unit that came with the car (useless as the Japanese use different radio frequencies to the UK!) and see that I have a width of 172mm to play with and a height of 147 mm with the HVAC controller living above that (with warm pipes coming out of it :( ) and a removeable cage for your rack of AV equipment.
I was looking at the LinITX LCD as it's quite cheap, but at 179mm it's just a little too wide. I assume the casing comes off but have no idea how much room that will gain. There is a small gap of about 5mm between the facia and the metal mounting cage, so if it's just a piece of circuit board inside then this will be ok, but these are things I cannot find out before handing over my money, so has anyone already done this?
Presumably I can mount the MiniITX board behind the LCD, but 2mm is cutting things a little fine. Anyone attempted to put a MiniITX board into a DIN slot?
I initially planned to run Linux on a RAID0 set of Compact Flash but there is no useable satnav software for Linux, also there is a cool program called DeltaDash for monitoring the Subaru ECU available from EcuTek which is also windows only. So it looks like Windows is the only choice. Since I plan to use hibernate, Windows 9x is out of the question as it cannot handle the uptime. NT4 is out of the question because of the need for USB, so I have a choice of 2K or XP. I'm leaning towards 2K as it has less garbage slowing it down but do you have any thoughts on this one.
Either way, I am informed that CF is a bad choice for Windows installations because it can only take so many writes before dying, so a hard drive it is, is there a good way to cushion the HD against the GeForces incured as a result of "enthusiastic" driving. This way I get to dump my entire MP3 collection as well.
Tank Circuits? (in the FAQ) I was under the impression the Opus PSU could survive engine cranking. Is this not the case?
GPS will be acheived via the NMEA output on my Origin B2 speed camera detector. I'll probably be using MediaCar for now, I assume the GPS button launches your choice of satnav proggy, and that you can configure other buttons (I want one for the DeltaDash program)
Bluetooth USB dongle? with this I assume I can get mobile internet, but more importantly add a cheap microphone and get a handsfree kit, how well does MediaCar deal with this? What other software do I need?
So I'm guessing I need:
Mini-ITX mobo of some description
Opus 80W car PSU (which includes a separate 12V regulator and built in shotdown handling)
2.5" HD and a rubber mount of some description
slim-line slotloading CD drive, bracket and adaptor
A sheet of plastic that's easy to cut holes in in order to make a facia (I intend to have front-mounted USB and RJ45 connectors
4 channel 25W RMS amp.
Do I even stand a chance of getting all this to fit, and have I missed anything?
