Hmmm .... another carpc nut, im not sure if theres many of them about here these daysOriginally Posted by shotgunefx
Well you know the motto of this forum, and and then again.I've done some searching but haven't quite found the info I'm looking for. If I've missed it, my apologies.
Ok, not a bad startHere's the hardware I've got so far.
8" lilliput VGA touchscreen.
Hell they must have cost a mint - 100G/11ms is pretty damn good, -20c good too ... just a shame that even both together you still only have 40Gb, and 4100RPM is slow as treacle .... most recommend a normal 3.5" HDD, do you live in antartica or work in death valley or something?2 Endurastar J4K20 automotive drives. (One for core functions, one for music/etc)
Oh wait - this is a newbie forum, perhaps its a scanner to find some trees?Traveler keyboard.
Hey, that shts got more than two wires, your in deep nowSavv backup cam.
Memsic 2125 Dual-axis Accelerometer
a jelly belly bean dispenser?...some other goodies
could do worse- perhaps a bit of overkill but i can see a theme hereStill need to aquire a GPS, was looking at a Holux.
Phew, you slipped that 3 in 1 question in fast.Pretty much the big holes left are what to actually use for a box and how to power it and networking
Yeah, easy, slam it in a tower, box it in with some plywood and glue some carpet to it- noone will ever know.I was thinking mini-itx, but not so sure. I'm not too concerned with accessibility, so it could be a 1/2 tower in the trunk (which is what I'm using now for playing around).
Opus is the king of 12v dc/dc around these parts, closely (but no too closely) followed by the carnetix. The Opus 150W is about as far as you can go and has a far wider range of shutdown options than the 90w.Opus looks promising for the power supply.
at 20Gb a drive yeah you need to.The mac-mini is interesting but I don't believe it has serial ports which is a problem. Plus I'd like to utilize both drives.
Well if your adept at it then all well and good, however you cant write everything yourself and youll cut yourself out of 95% of the help if you have problems with the few packages you can get to play nice together. Its up to you but perhaps dual boot an xp partition for all those custom apps that are floating about here.For software, I'm pretty much set on linux. I'm thinking as far as the UI, I'm going to write my own as I've got some special requirements.
Thats a bit risky isnt it? Even with the best gear and running linux, I bet it will crash sometimes, then what do you do? Fit a hinge on the lilliput so if the worst happens at least you can see whats going on.The ultimate goal is to replace my gauges with an 8" lilliput touchscreen and a complete digital dashboard. Actually I'm going to leave the gauges in place hidden behind the touchscreen so I can avoid rewiring everything that passes through the instrument panel.
Burble burble burble Get your azz into the OBD forum, really you dont expect us to belive you are a newbie talking like thatI can get most of what I need via OBDII, but some of the signals I'm going to read directly (tach/speedo/etc) with a PIC and transmit it to the pc via serial. My car is ISO and I only get 3 or 4 samples a second which is way to slow for the tach and speedo.
You mean suspend to ram (takes a current to keep the ram in a constant state of refresh) or hibernate (dumps memory to disk and shuts down needing no current beyond usual usb and wol sense)? Both work fine in XP, I take it you are not intending to use W98 (I wouldnt) as you know its flakey.So one of my big problems is going to be getting boot time down. How does suspend to disk stack up? I've only ever used it on my win98 laptop which really never worked. It suspended fine, it's resuming that's problematic.
On Linux, W98 or XP? Most use things like XP lite to hack out what they dont need - as before, the more you look into specialised apps, the less and less people can help you.I read an interesting article on IBM's developer works awhile back about using make to parrallize init that was interesting so I'm planning on giving that a try.
Well there you go, you wanted linux ..... I mean I dislike the way the M$ monopoly throws its weight around but for sheer compatability in nonstandard applications like this, its nice not to have to worry wether the you have to troubleshoot the o/s for more weeks than it took you to get the hardware together. Anyway, have a look at the TD-SCDMA, not sure if its out yet but its using Trolltech's Qtopia, not sure how useful it will be for you but its a step in the right direction?As far as networking, I'd like to get a Bluetooth enabled phone that I could use as a modem. I was looking at the LG PM-325 from Sprint (my current provider), but I've had terrible luck in the past trying to get linux compatibility info from providers. Either it works when they say it doesn't or doesn't when they say it does. Anyone get this to work with linux?
Joking aside (hope you have a funnybone ) You are probably better off breaking your post down and taking it to the seperate forums - noobs tend to know a lot less about what they are doing than you do.Any words of wisdom would be greatly appreciated.
