do those dc to dc solutions work for laptop use?

Depends on the laptop. The DC solutions I have seen are targeted at desktop models. There may be others. The issue is really what your laptop requires for power.Originally Posted by bud_d
antimatter, did you figure that out on your own or read my sig file?
Yes, I say search because most installs are different.
That means the answer is different.
Also, by searching and reading you might find something cool that will work in your install that you did not think to ask about.
I bet you are one of those people that just make judgements on very small amounts of information..... see what I mean.
Tons on info here, very few cookie cutter solutions. The closest in my opinion are:
DC to DC OPUS ps
and the indash one din VGA XENARC
Lots of folks seem to be using the small VIA mainboards as well.
That is bull.
I've been using an inverter without any noise WHATSOEVER.
Now that I've switched to DC-DC, I'm getting an engine noise.. whining.
There is no metal on my plexi case. There's no way to ground my case.
There is no doubt, inverters make the best choice for noiseless power supplies.
THe only thing DC2DC has got going for it is the size of the installation
Why'd you switch then? Are you switching back?Originally Posted by masch
You must be the only one.Originally Posted by masch
Did you make any changes to your grounding set up when you went to DC-DC?
What inverter did you use that was noisless?
I am sure the rest of the folks using inverters will enjoy your wisdom.
I'm using a coleman inverter for my setup and haven't had a problem with noise at all. there is none which is surprising considering I don't even have the case grounded. but I'm not complainingOriginally Posted by TruckinMP3
I tryed using a inverter as I'm using a PC, but a very small one, with a external psu.. this doesnt enable my to attach a opus.. so to start with i had one I payed £25 quid for from maplins.. this didnt work as the output from this is a square wave, and caused massive buzz through my speakers when on.. so then I bought a sine inverter.. this solved the buzz.. but I then gained a brick in the boot, also as my car is a estate the noise from the cooling fan was a mare.. so this went back.. I just bought a switchmode inverter.. this is a special made just for PC's it cost just over £60.. its very small no noise.. and it WORKS.. its rated at 100w which is just enough for my dell. I got it from www.cpc.co.uk there website is also www.switchedmode.com the unit I used was product number sm2911. It has a 12v lighter on one end, and a IEC kettle socket on the other.. they also do the clover plug ones and the figure8 ones.. Awesome for those of us where DC-DC isnt a option
I switched because of the size of the setup. An inverter is like another brick to be placed behind the dash. The DC2DC solves this issue, but I didnt know what people were talking about (noise) till it was installed.
Anyway, it wasnt really noise, I think its more of hearing the high frequency engine whine.. its directly proportional to the RPM.
I didnt ground anything with the inverter and with the DC2DC. How do you ground a mobo in plexy? connect the screws or what? If only I can simulate the environment at home then I may find out what's the reason of the whining. In the car with the cramped spaces its much harder.
My inverter was 300W from Maplin Electronics. It ran a little hot so I had to take off the top and put a cooling fan on it.
Actually, I agree with creating a sticky. Instead of sending the poor hapless dudes (and we all know by now that we are ALL dudes) on a crazy search from which there is no return, let's put stickies up for the oft-covered topics so that the new posts will be more likely to be about something from which we can learn.Originally Posted by TruckinMP3
I understand that posts of the same questions over and over can be tedious and trying, but for pete's sake, that's what the stickies are for, ne?
Just my two cent's worth.
