Starting out - rate my Build Specs - 1995 Volvo 850 - Advice on Screen/CPU/PSU
Been reading this site for a few years and getting closer to tackling a CarPC build for my 1995 Volvo 850. Previously, I've done the quick n' dirty Crutchfield HU-install a few times and in '07 started to fab my own brackets n' such to secure an Alpine IVA-W200 in my 850.
The Alpine interface drove me nuts though, and showed me I need the full control of a CarPC. So...
I hope to get some input on my build plans and move to ordering most of the components. I'll post progress on this site as I go.
My plan isn't fully detailed yet, but any advice on my overall approach would be GREATLY appreciated - recommendations on better-suited equipment, placement of components, etc. Wiring isn't my strength, and though I'll need learn more about it to get this done, at the moment I'm very concerned about too much heat around the CPU case and picking the proper PSU.
Here's my approach:
TOUCHSCREEN: Lilliput install in stock-HU cavity, replicating Liquid Kernal's LCD placement:
Concerns: Screen readability in sun-light. Has anyone experienced a brand/model screen that does best in "viewable vs. glare/sun"? Should I consider any other models besides Lilliput's to maximize performance in this area?
CPU/CASE: Going "package" here, something along the lines of the following:
VoomPC-2 Car PC Barebone
BOLDataź Mini PC
The key point on this is that I hope to mount the unit in the glove box, similar to modnut's approach. http://img79.exs.cx/img79/2862/glovebox3qj.jpg
Concerns: Heat & ventilation in the glovebox - too risky? Do I need to cut some holes? If I want to stay with the glovebox, but can't ventilate enough, do I reduce heat generation by going with a VIA mini-ITX or some lower-heat MOBO/CPU combo?
PSU: Yeah, this is where I'm looking for some serious advice. I expect to go in the direction of an OPUS DC-DC unit, if only because it seems to be widely used and reliable. Not entirely sure how to match a unit like this to the specifics of my car's electrical system. I'll prob have to search around the forums a bit more to even pose intelligent questions on this one.
Concerns: Deep-frying my 850.
There's certainly more to include in the plan, though these (above) are the biggies, I think. I'm also figuring on the following:
OS: XP (TinyXP?)
GPS Receiver: ??
GPS Software: ??
Wi-Fi: ? (on-board/dongle)
Bluetooth: ? (dongle, I assume)
And ultimately I'll look to provide capacity in my system for the following abilties:
-Wi-fi updating of my music file collection from my driveway
-Rear View Camera
-Sensor Monitoring/Integration: Digital Gauges (Temperature, Fluid Level, Tire Pressure)
-Onboard Diagnostic System (OBD-II) Monitoring
Not really interested in: Watching movies or gaming
I'm doing more bottom-up learning, but any thoughts from those who've already gone through this would be greatly appreciated!!
