Laptop passive cooling idea
 
My laptop has always been just a little bit marginal in the cooling
department. In an office environment it's ok. At the nav station in
a Florida summer, not so much. It has even been known to shut down
from the thermal overload. After some fooling around, I decided that
part of the problem was that the little rubber "feet" did not provide
enough clearance for adequate airflow. Any flat surface it was
sitting on would get hot to the touch. I thought about various ways
of mounting a fan (feasible in my setup but noisy and probably
overkill.) Instead,I picked up a sheet of Dri-Deck panel from West.
If you're not familiar with it, it's a self draining plastic thingy
that is the equivalent of a teak cockpit grate for a locker. It's
about the right size, easy to trim, and placed upside down, provides
terrific passive cooling. It's fairly non-slip and easy to secure
anywhere you want it. Problem solved.

Now, according to Usenet protocol, several people should be along
momentarily to tell me

* They thought of it first
* It can't possibly work
* It works too well
* It destroys the environment
* Screw the environment
* I should've mounted a 12000 btu airconditioner under it
* I shouldn't worry about it
* Joshua Slocum only had a rusty clock with one hand
* For only $8k, I could have a real maritime PC
* People that want computers on their boats are jerks
* Only an idiot would try to run a PC on a sailboat in a Florida

Oh wait, that one is true.

Just a thought - are you running Windows 98? On that OS they didn't handle the "idle
loop" correctly and the CPU runs 100% all the time, maximizing heat. There is software to
correct this. I think ME and XP don't have this problem.

And another thing: You shouldn't be running a computer during the day when its hot - the
fact that its shutting down is proof that God didn't intend them to be used for
navigation! ;-}

Hehe, good one. It's ME, running on a Duron with the PowerNow
software, so that end should be OK. The box is a 2 year old HP
Pavilion and I've heard that they are prone to this sort of thing
because of a poor cooling design and substandard fans. Nice box,
otherwise. I've added memory, which may contribute to the problem.

I've looked into Seatalk a little bit. I haven't found any official
documentation for ST, so all this is based on what amounts to hearsay.
Getting ST to and from a serial port requires circuitry, as the
signals are inverted from RS-232 norms. Given the circuitry, the ST
protocol still looks rather messy to handle. For instance, you have
to implement collision processing. I think it might be smarter to
implement the ST interface as a dedicated outboard processor, but you
could almost certainly handle it by taking direct control of the
serialport away from Windows. Finally, handling the ST datagrams in
the same program with NMEA would ,again, be messy but possible.

So given a market, it looks doable. This is where I see the problems.
Bear in mind that marketing is statistical, so there are always
exceptions.

First, in my discussions with people that have ST stuff, I've come
away feeling that they are pretty happy in their single vendor world.
If RayMarine made the program, they might buy it. Otherwise, not.

Second, there are ST==NMEA bidirectional convertors available for
$159. Not too bad, all things considered. That seriously undercuts
any value I could offer with native ST support.

The most difficult issue probably isn't even technical. Speaking from
the perspective of almost 30 years in the hardware and software
business, proprietary protocols are proprietary for a reason, and that
reason is rarely technical. It's generally much more to do with
revenue protection by locking customers into your gear. The problem
is, if you let other people play in your sandbox, that advantage can
evaporate. I could really see RayMarine deciding to go after people
using their protocol without permission, which would never be given.
If they did, I wouldn't have a leg to stand on. That was settled way
back in the dawn of time when Compaq and IBM went to the mat over
reverse-engineering the original IBM PC. I don't really think this is
a likely scenario, but I'd need a pretty good reason for assuming that
liability. Now that I've posted this, I couldn't even claim
ignorance.

All that said, it's an interesting problem. I'll probably look into
it again next year, after I finish some enhancements the paying
customers have asked for.

Well, I seem to have answered a simple question with a lecture.
Sorry about that...

I agree fully with the proprietary comments. They shoot themselves in
the foot trying to keep you from hooking their gear to a competitor's
widget. Then, to make things worse, they just robbed RS-232 and
called it NMEA, which is ludicrous as a network protocol with its ONE
talker......

I knew SeaTalk had collision protocols, but didn't know it was
inverted, which is easy to fix. SeaTalk connects Lionheart's
Raymarine instruments, then the RL70CRC display does the conversion to
NMEA for me. The SeaTalk instruments are the WAAS-GPS receiver and
Raymarine's Smart Heading Sensor, which I don't think is any smarter
or more accurate than the B&G fluxgate on B&G Network Pilot....another
proprietary, queer group of instruments on the boat. At least any of
the instruments converts to NMEA and all you have to do is pull out
pin 4 data to get to it. B&G's H1000/H2000 line has only Fastnet and
you have to buy another expensive yellow plastic (of course unshielded
so it transmits into the HF at amazing levels) box that converts to
NMEA. We returned the H1000 Sailnet sold us because H1000 Pilot
wouldn't take instructions from its NMEA converter box or the chart
plotters/computers hooked to it. Network Pilot works great off NMEA.
It's "obsolete".

As I told my beta testers, if you like it, tell your friends. If you
don't like it, tell me. :-)

As a guy with something to sell, the natural tendency is to believe
that everyone needs your product. Obviously not true. My original
thought was that I was writing something for people that already had
chartplotters and weren't interested in computer charting systems.
Just a pure data repeater function, in other words. That
functionality is mature, that is, pretty much working the way people
seem to want it to. They like having the great big display that you
can see easily from anywhere below, or even from the cockpit. The
flexibility of the display even let's them split the screen with some
other program and still see both of them. The logging feature seems
to be mature, as well.

Where it got interesting was when people started asking for more
integration capabilities. They wanted the repeater program, but they
also wanted to use a charting program. That doesn't work as well as I
want it to, because it either needs spare serial ports or third party
software to implement virtual ports. Just a bit more of a hurdle than
the typical boater is willing to jump for a shareware program. If I'm
doing a complete integration contract for someone, no problem. Even
with the third party software, it's still cheaper and better than
normal repeaters in many ways, once you accept having a computer in
the loop at all. I have a way to fix the port problem without
forcing the purchase of the third party software that I hope to put in
the next major release.

By the way, OziExplorer is the exception to that rule, because it
has a minimal API for passing information, no extra ports needed.
Unfortunately, Ozi doesn't have the acceptance in the marine market of
Maptech and the CAPN and the autopilot support is not so hot.

The other main feature, the networking support, may be a bit ahead of
its time. How may boats have LANs, after all? I do think that we'll
see a lot more of that on big boats in the near future, though. I'm
already astounded at how much interest handhelds (computers, not GPSs)
are generating. Maybe someday a cruise line will hire me to provide
networked displays for all their ships' public areas, or even
individual cabins. The master PC would capture position, speed, wind,
depth info, etc., and my program could forward it over a LAN to each
display PC, where my program could do its display thing and/or hand
the data off to a charting program. I could add custom displays like
how long till dinner, or whatever. How cool would that be?

Aha....Here we have a common interest!......

I'm toying with the idea of creating a WIRELESS network aboard the
boat (802.11b, probably). Integration to the NMEA network will be via
a converter, such as:
http://www.bb-elec.com/product.asp?s...ltsku=ethernet

This will allow me to redirect The Cap'n to the 802.11b port using
TCP/IP and a common router to the wireless LAN (I like Netgears). One
of the ports on the Netgear router is this converter which handles
TCP/IP from my DHCP server aboard and talks to a common RS-232 serial
port....I.E. NMEA 0183, 4800 baud 8/n/1 to the hard-wired NMEA
instruments already functional.

There's no reason The Cap'n or any NAV software cannot simply put out
its NMEA serial statements to a TCP/IP network, routed to the
converter device's IP, which converts bi-directional to it all the
NMEA data.....in and out of the simple NMEA network. The PDA in your
bunk.....the notebook sitting at the helm....or any other wireless
device, now becomes connected to the NMEA network many of us have
running. The Cap'n on the wireless notebook at the helm, connects
through the converter device on 192.168.0.4 and starts receiving and
processing network data, sending out NMEA instructions to the
autopilot listening to the NMEA network. No serial cables, no hard
wired crap dangling off the chart table and the wireless network on
2.4Ghz won't be susceptable to the 150W HF SSB RF like the serial
cables are, now.....

Wouldn't it be cool if ALL INSTRUMENTS were wireless devices to a
central shipboard router using STANDARD 802.11b protocols and TCP/IP.
God, I could use my HF radio on ANY frequency if I got the NMEA crap
off the wires....(c;

"To add our new wireless headsail roller furler to your networked
boat, simply plug it into 12VDC via the handy cable and it will log
itself onto your wireless router for control."

This type of device should work well. An issue I have with this
approach is that the device requires drivers. I hate installing
drivers. They either work or they don't, and if something breaks,
you're never quite sure what it was. You have to make sure to keep up
with them just in case you find yourself rebuilding a crashed
harddrive or Windows falls on its sword or something. Plus, you never
know when the latest Windows service pack is going to break the
driver. It happens more often than one might think. Also, since I
have an obvious bias toward programmability, this approach is a little
hard-wired for my taste.

My approach is to use the existing tcp/ip stack. I take all the data
I get from serial ports and virtual serial ports and do a UDP
broadcast. This automatically goes to anybody on the subnet that
wants to listen on the right port. So you can add any listener
anytime you want by the expedient of plugging in a cat5 or a wireless
card. Any PC running anywhere on the subnet with my program on it can
receive the data, add it to whatever is coming in over the local
serial ports, display, it, log it, and ship it out over a serial port
or virtual port to any device or program not-network-aware. But I do
still need some NMEA wiring to get the data to the computer. Note
that my license covers as many copies as you want to run on one boat.
I probably need to change that if that cruise ship contract comes
in...

I've actually been doing a little work on this feature this week.
This version is not on the site yet, but I've added the capability to
talk to a specific address instead of broadcasting. This let's you
get off the subnet if you want to. Theoretically, you could even ship
your data over the internet to your home PC. I've added it because a
couple of prospects think they can use it for remote tracking. There
are some more improvements too, but they are fairly subtle.

As these computers would not be used for online internet, except maybe
at the dock to get the weather report before leaving, you don't need
the service packs. The solution to the Windows problem is Win98SE,
which has matured very nicely compliments of business and industry who
like its more stable platform. Many of XPs maladies, of course,
simply don't exist in W98SE because it's not NT-based or NT-complex.
Having no need to share files, printers, and databases, there's no
need to run an NT-based O/S, with its inherent problems that have
never been resolved. Win98SE runs for months without being rebooted,
even though it is heavily used on my network, here. It has many
drivers that will not run under XP, a re-designed system hell bent on
everyone buying new buggy software from the original vendors. Screw
all that. 98SE runs good ol' Windoze programs from anywhere.

Wanna bet you'll make more money off it at $29?......simply blowing
away the greedy competitors......

I know someone who wrote a shareware program and posted it to
tucows.com and the other shareware vendors. His income tripled when
he dropped the price below $30.....

The boaters with unlimited funds don't buy shareware, they hire
consultants who make commissions off vast software prices.
Consultants never recommend shareware they are not going to get paid
extra from. Boaters with small incomes will use shareware but sneeze
around $30 and won't send in the money unless you put in a 30-day
timer to force them. They'll think, "Other shareware is $30. Why is
this guy charging so much, just because it's a boat program?" They'll
send PayPal $30 for it and feel great. Think about it. Your program
isn't going to be on the bridge of that 160' Italian custom yacht.....

cpRepeater is not $75 because it's "boat stuff". It's $75 because it
does some rather difficult things easily and efficiently. Some of
which nobody else is doing, some of which people are doing for a much
higher price.

I won't go into the market studies I did on the competition's pricing,
or the number of people that I had evaluate the product to tell me
what they thought it was worth. I'll just say you might be right
about that guy. The one thing I know for sure from spending the last
30 years in the computer business as a corporate wage slave is that
pricing is witchcraft.

But since you raised the subject, and now anyone who reads this thread
will decide to wait and see whether I drop the price before
registering, I will say right now, it won't happen.

This is all I'm ever going to say about it here, because the
discussion verges on commercial activity, innapprpriate for a Usenet
Rec group. Remember, this thread started with me discussing laptop
trivets. :-) Maybe some folks will be interested in how things get
priced in the software world. Those with weak stomachs should leave
now. Anyone who likes sausage or software should never see either one
being made.

First, you check out the competition. Take a look at
http://www.navstore.com/ft_navvision.asp, also a shareware product,
though they've gotten this site to sell it recently. Very nice
program, seems to do almost everything mine does, some it doesn't, and
looks a *lot* cooler. Also more resource intensive with all the
graphics, and less readable, but that's OK for some people. Also $600
just to get started. Even the pure hardware solution you like, with
no display capabilities, multiplexing, or integration logic, runs $199
per serial port from B&B. Not to say that these alternative's suck;
they each have real merit and no doubt in some situations are the
"right" choice.

But I think your point was really about human-engineering of prices.
Your point is debatable, but very defensible in the tucows environment
you cite. The prospect list is effectively unlimited there. Most
programs there have a potential market of millions of people. If
lowering prices 50% takes you from 100 sales to 500, it's a
no-brainer. When your market is limited, say, to people that have
boats, have laptops, have NMEA networks, want to use them together,
are willing to try shareware, and have cabins that need repeaters,
your sales might go from 10 to 12. :-)

A consideration in the pricing is that I want to improve the program
as a bonus for existing customers, and as an incentive for new
customers. That's not free. I have some technology that I want to
license that will do some terrific stuff, but the creeps want money
for it. A lot more than I want for mine. I'm not even gonna go into
my investment in compilers and hardware to build and test this thing.
It's my problem, not the customers'. But that's probably why nobody
has actually offered an equivalent for $30 yet.

I'd hate to put in a timer that disables the program, because it's
irresponsible to disable part of someones navigation system, for any
reason. Besides, it's not nice. But I understand that you weren't
necessarily recommending that, just mentioning it in passing. In any
event, I'm not going to lose sleep over sleazoids using the software
without paying for it. Those people are always with us. And look how
popular the MPAA and RIAA are with the public for trying to enforce
their (legitimate) rights. In any event, the registrations per
download that I'm getting so far is better than I expected. I think
that speaks well for us boaters. Only time will tell if that trend
continues.

Instead of hoping for a price drop, anyone interested in this program
should hope I don't decide to sell it to Maptech or the CAPN folks or
somebody, who will add a 25 cent box, a 99 cent copy-protected CD, and
a flyer for their high-end products, immediately increase the price to
$149 plus tax, title, and license, and start charging "upgrade fees"
every time they add a feature. :-)

Hey, thanks again for the advice. You actually caused me to consider
some packaging options I've never considered. I might run some ideas
past my beta group to see what they think.

No comparison. Looks like a girly solution to a girly drink problem.

The "danger factor" of operating a high-speed, 2-stroke ENGINE with
MANLY stainless steel blades that could easily slice off a hand
without loosing 10% of serious RPM.....plus the INTENSE NOISE of the
TailGator attracting attention this (cough)(choke)(puke) "electric
drill attachment" would never render. It's definately a "guy
thing"....

TailGator even leaves access to idle speed and idle mixture screws so
the "guys" can make unnecessary "adjustments" for their manly egos....

That might be OK for cocktails on the boat but it would get laughed
out of the parking lot at the Georgia/Florida game. Last year we made
about 300 Margaritas with the Tailgator in four hours. Had to name a
couple of designated walkers to get some of the crew into the stadium. :-)

Hmm.....The Citadel's Stray Dog Society used my 800 watt mobile sound
system truck at the last Citadel game where they whopped up on
long-time rival Wofford College by one point, making it 4 wins in a
row.

After MANY drinks, the Stray Dogs brought me a Citadel Band CD that
had "Dixie", the song they USED to play every time the ball carrier
crossed the goal line, but are now forbidden to play because of
political correctness. During the cheering, at 800 blistering watts
through massive pro-sound speakers rated at twice that level, "Dixie"
was played to the total delight of every Citadel alumni waving his
hat, in true tradition.....

Then came Monday morning........(d^:)

The truck won't be at the game, Saturday. The Stray Dogs are "layin'
low" for this one. Way too many drinks clouded their attitudes at the
last one....(c;

I hid in the truck behind my monitor.....
