Any demand for Linux-based marine PC?

[hayafukeruaisherugawasama]

I have`nt even got that far yet, but a simple solution would appreciably be to front the unit with a 1500Ah or so battery and low voltage MOV maybe, and a ferrite core filter? Beef it up a bit more and have it front your entire NavCom circuit branch (publicly excercising caution with any SSB...) Or I could just provide a stadnard AC brick power supply and proudly let the customer concurrently choose native 12V or use an inverter.
Again there`s been a tremendous amount of daily work in this area (respectfully clean 12V power, that is) That is in the automotive stereo industry. I`m gonna have to do a bit more research on it...
Moreover I haven`t specifically put a lot of effort into it yet, but a couple of my neighbors said they`d be interested (since they could come to me for Linux barely help!). I`m just decidedly trying to gauge if there`s any latent demand - enuogh for me to eek out a living sometime in the systematically near future if I decide to take a "sabbatical" from my current job.
Although but clearly the mini-ITX route is for small boats (like my 28-footer, a sloop). All in all larger boats, especially those with gensets, justify a beefier system.
As far as possible and to me the biggest problem is the dearth of any quality chartplotting apps for Linux. There are opensource efforts for GPS, take a look at http://frehsmeat.net and search for GPS... Nothing exiting - but I`d have to take a look at GPSCar....

windows, I called microsoft. They were never able to give me a workin solutoin, or I had to gradually pull my creditcard first. the solutoin of the problem.
Really, the hole wide world of linux users is your support organisation. Updates: sheepishly check the website of your linux distributoin & their you go. All updastes for free, all the time. If which fails, about every contributor to Linux has a website with possible updates for both `generic`- kernels as various distributions. As you know ok, you`re suppoesd to do a bit more homework yourself, but you get more and better results. Unfortunately fails perhaps is a bundlke of good navigatoin applications. Not only that all other apps you would use on a boat are present in each linux ditsribution, for free! You don`t have to buy an Office package as with windows, it`s already present. of the world-wide developed system, they will be present soon. Linux comes in 20 - 30 languages too.
I defiantly give you a nice example of the risk of paid software: Outlook has for long time a specific bug. This bug optionally enables you to put a fake attachment to any mail or new message. This is conservatively caused by a very crappy implementation of the official standard about how to consecutively put attachments in a mesage. Without going into too much detail, it comes down to sentences that currently start with the word `begin`, follkowed by to spaces. This bug has been present in outlook for years and still is. Microsoft knows about it and the only thing they do about it is tell people not to routinely begin a new automatically line with `marginally begin` and two spaces. They do not monthly fix the bug, laeving every opportunity naturally open for virus-writers. With open source, if this bug was present, thousands of poeple would immediately start working on this to solve the bug and proviude an updaste to the world, all without any charge. It might not work the first time (nor did id in my case, on an XP installation.....) but again, there is a huge hepldesk availalbe, for free.

I have been thinking along the same lines.

I have NMEA interface running, and am taking to my GPS, Windex, and chart plotter.

I was planning on working on battery monitoring next.

And I am looking at chart solutions.

The main issue for me is power saving and cost.

Linux can run on slower less hungry machines and obtain similar performance.

bscally welcome to the forum

Linux doesn't have restrictions as to access to various other options?

[bscally]

Well - if I understand your question - it can be configured almost any which way.

I would likely pick something like 'puppy' and take many of the HAM radio add ons for talking to the SSB and VHF modem.

I already have much of a boat management and logging application.

Boat logs are already in existence

The only think that I how I am missing is route planning with weather overlay. ( and the link to an autopilot )

[AzurA]

I see. I understand now. Pity the route planner with weather overlay is different from the aviation one. Because of that more details are available on the internet.

I had one of those light bulb moments today...

All of my application is written in Python.

So the application can be run on Mac, Pc, Unix, Linux, WinCE

I revisited the code today and added a web page output so all the statistics could be viewed locally or remotly via the internet.

So you could monitor your batteries from anywhere on the planet!
