How much was the computer you use?

Best you be sitting down for this one too. It was up around $1200 at the time. The Celeron M put the cost up I seem to remember. However it was a lower power option. The RAM had to be low profile to fit.

There seems to be more choice now so I'd imagine you'd get away paying much less.

The whole computer is about the size of en external CD burner and made of aluminium. The CPU contacts the inside of the case (thermal paste required). Runs silent and there are now fans to fail!

Hehehe. I did use an inverter for awhile while I investigated the DC-DC regulator. It was only a temporary thing.

The regulator will be more efficient and you won't have 240V floating about in the car. My inverter also had a fan that was noisy. Drove me nuts.

Hence why I dont use an inverter in the defender... Fans just too noisy

LOL.

I would never hear an inverter fan in a Disco bever mind a Defender!

If your Disco is quiet enough to hear a fan....tell me what you have done cause I will do it too.

The internals run on 12v and 5v anyway, there is nothing in a pc/laptop than needs 240v

There are quite a few ciggy adaptors available to run laptops - and the more expensive seem to have the bits in to remove spikes and troughs

More details please.

lots of good ideas at www.mp3car.com and the smaller (cheaper) motherboards are here that everyone uses http://www.mini-itx.com/

For the people with the DC-DC Regulators where did you get them from and how much?

**walker** · 7th February 2007, 06:34 PM

Jaycar is probably the best place. I got mine on the net from somewhere in perth about 3 years ago. I think it was $30. It is a multi voltage unit.

Did you ever get the screen?

I am getting interested in using a surplus laptop with a GPS mouse linked to a screen.

best regards

yes thinking of having a go at making the one for the new defender

except i'm thinking of using the mini board that takes compact flash as you can get 8g ones now and if i remeber correctly it only needs 2g to run xp something like that

i dont know alot about comps so i'm sure someone will gallop straight in and correct me

the reason i was looking more into a solid state drive was for reliablity i wasn't sure that a hard drive could sustain a long battering on corragated roads with the vibration which is what we will be doing next year to kakadu and that is the whole reason i would like one to store all maps on and use gps
