You can get slot DVDRW drive that dont have a tray, much like most head units. ie cd slide in by a motorized roller. Dont know much power they eat up though, but that's what I'm gonna be doing. Then you can get the best of every world, cd, cdrw, dvd, dvdrw.

most laptop cd/dvd drives are cd-cdr-cdrw-dvd-dvdrw-blah blah these days. If you can get your hands on a slimline drive go for it.

It would be really cool in the dash under the screen if you have a setup like Parish's in my opinion.

Hey has anyone got that USB boot thing working yet?

I've read through some of the website but haven't been successfull in getting my USB key to boot the OS. It boots off the key but stops cause it can't find some system file that is part of windows.

Yeah I read through that same guide, got it to boot but said there was a particular file missing, one need to boot up windows or something.

Pretty much stepped through it exactly but something still ain't right. Oh well I'll keep trying!

hey just found this thread, what a fantastic idea with the car-pc!

i might add a couple of improvements tho, firstly you could get a USB 802.11b/g wireless card... you can get external antenae for them also to improve reception, hence eliminating the need to transfer files/data via a cd drive or usb key. Obviously secure it or disable it when you dont use it!

next for those who are having issues booting off usb, you can buy things called Disc On Modules which are in effect, flash memory built into a 40-pin IDE connector.

So you plug it into the HD connector and it should detect as a HD... havnt seen prices for anything larger than 128mb, but they say theyre available up to 1.5gb. Keep an eye out for them, they may be the next cool thing.

As for speed with flash memory well there are pros/cons, most memory has extremely low latency (fast seek time) but transfer speeds are low compared to HD's. Also they have no moving parts. So would be great for opening/moving small files, but churn with large file copies etc.

I've also heard of some ppl using mini-ITX boards with Compact Flash adapters onboard. Lots of modems/routers use this method for booting skeleton versions of Linux, but I cant see why Windows couldnt work. Compact Flash cards can be bought in sizes up to 3-4gb im fairly sure.

Anyway nice work to those who have made them, got me motivated for when i look at stereos in my car :thumbsup:

What do you call fast booting?

Restore from hibernation is quick enough for my carputer.

ditto. Keep the RAM size small (256MB for me) and return from hibernate is plenty quick enough.

If you had a dual battery setup with isolation circuit, you could even keep the pc in suspend-to-ram mode for instant turn on. A deep cycle gel-cell as the 2nd battery should keep suspend mode going for a few days.

with mine keep a 1000cca battery with a isolator off the main battery. I can run it into the ground and the vehicle still goes. when I'm on site I plug the van in and it switches straight to mains and shuts the inverter down. remove power and it fires right up without a glitch.

hardware wise: 7 port usb hub HP 1200 laserjet printer,40gb hd, 4g RAM, 3g modem, keyboard and mouse. 3kw inverter

display wise 17" LG monitor. base machine is a acer laptop. OS is winXP - extra memory is for quicken - its a memory hog!

it will run 3 days before shutting down. I use it daily for invoicing and general internet when I need info quickly.. it is also networked back to the workshop SBS server (quickbooks sits on this.)

the whole lot in integrated in the floor of my van . (if someone knows how to empty a nokia N70 memory card without the lead I'll show you the pictures.)

I didnt really consider a second battery thinking that the time it would last wouldnt be that great but a few days you say? awesome, whats involved in putting in a second battery and an isolation circuit?

you can buy them:

or make them (search for isolation circuit, or tank circuit):

      V37 Alarm settings and what the buttons do.

      By HYBRID VL · Posted

      I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models?

      R32 Gtr Long Term Love, Now Project

      I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again

      Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!

      curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.

      Rear suspension upgrades

      By Dose Pipe Sutututu · Posted

      S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
