Skip the computer and just use paper rather than deal with a sluggish computer
My favorite boat computer is a Toughbook that I bought used for $265
or so. It's more than adequate for managing charts in BSB format,
browsing the web, reading EMAIL, etc., and it just keeps on ticking.
And last, though certainly not least, is the limited contrast / brightness.
How can you read that out in the cockpit?
I couldn't - and that was in the shade.
That must be why they use them outside on construction sites and for
Law enforcement work. They obviously don't need to be able to see the
display in daylight!
The toughbooks are specifically DAYLIGHT VIEWABLE.

Advertising claims aside, I couldn't read it very well in the shade.

400:1 contrast ratio isn't anywhere up to date.

Dear Richard:

Here is something to consider operating a used CF29
When buying used most HDs are reformatted. DOing so removes the
Panasonic drivers. One required driver controlls the brightness
controll. With the driver installed use Ctrl + F1 or F2 for
brighness. With oout the Panisonic driver it dont work all that well
or not at all.

I hope this helps.....

My CF29 has excellent outside brightness.

Maybe I should get one of those 3D 53 inch plasma screens that SKip
has. NOw that would be fun............... for about 3 seconds :/

Bob

Especially on a sailboat, power draw is a big consideration. Fast
processors draw a TON more electricity, as do unecessarily large
displays. What Cavelamb is claiming he HAS to have will be a bigger
power drain than a decent refrigerator. How is he going to provide
that much power on a small sailboat?


I don't HAVE to have it - just WANT it.

But your rant is out of date, Dog.

These are FANLESS systems.
They don't make that much heat, ergo don't pull that much current.

The display does, of course, but that's the same screen used for
movies, maps, chartplotter, etc.

I choose a VGA monitor rather than a TV because the extra circuitry
in the TV (tuner) pulls trons too. Monitors are significantly lower
draw.

And I'm still looking for a 12 volt drive monitor - just to lose the
20% from the inverter.

Built around a VIA Esther (C7) CPU clocked at 1 GHz the Pico can accomplish many
smaller tasks just fine. Geekbench rating for this kit was 384. Note: I wouldn’t
use this to recode video, but it’s perfect as a mini media center for a car or
for a home web server. One of the most attractive features is the low power
consumption. With power consumption around 13 Watts (20W loaded) the Pico will
cost less than $25 to run non-stop for a year.

Bottom Line
While this is not going to break any compute records, it is a solid platform to
build upon.

Depends on the boat - alternator size, battery bank capacity,
solar/wind chargers, etc.

Slower than a toughbook, which can be bought including a waterproof 12
volt display and keyboard for about $300.

What will it cost to piece together this SLOWER system, including a
display? What will it all draw collectively?




So how fast is you Tuffy?

(And please keep in mind - that one IS slower than the minis.

We are talking about Cavelamb's sailboat, with very limited electrical
capacity, as you would find on the majority of smaller cruising
sailboats.


It can hold out for two or three days.
And that's the limit of my cruising for now.
