[weather] Is this a valid / uptodate design for the barometer?

[Edelmann]

http://www.davidbray.org/onewire/barometer.html

has detailed info on the bray barometer. Is this link still valid from a
contemporary suggested barometer standpoint, or has it been replaced by
better, more stable designs. If the latter is the case, is there a pointer
to the currently favored design....?

thanks!

Thaught I'd start the barometer adjustments before venturing out to Maplin
in the AM to get a pair of variable resistors for the final calibration

However at some point the VR2 5k trimmer stopped working...
Does anyone have time to just have a quick look at Maplins site
http://www.maplin.co.uk/ and tell me if UH24B would make a suitable
replacement ?

The current Barometer has the trimmer pins in a triangle pattern....not in-
line. I think the current part number is on simon's site. It may not have
quit working--when I calibrated mine it acted real weird as I got it closer.

BTW, I used simon's trick--just soldered them in and adjusted from there--
it works. The cal tool can use most any value for the pots--just be sure
to use a good DVM to set them--(mine is cheap junk). I had to put in a
0.165" offset to track local BP, but it does track nicely. Expect to have
to very slowly fiddle the calibration in, it's very touchy. I went back and
forth about ten times before it was swinging right.

A good long burn-in once the cal is close makes it easier. 24 hours is not
unreasonable once rough calibration is dialed in.

- and the input voltage just begs for a little 12v lead-acid battery trickle
charged at 13.6v; my baro seemed to get upset when the power was interrupted,
and the hard-wired battery solved that...

There have been 3 "Bray/Jennings" designs published. These are:

1) Original version 1.0 -- http://www.davidbray.org/onewire/barometer0.html
This design had a transistor voltage level changer causing it to be too
temperature sensitive.

2) Version 1.1a -- http://www.davidbray.org/onewire/barometer.html
This design removed the level changer. This has proven to be a stable
design. The reason for the 'a' in version 1.1a is to indicate there were
resistor changes from version 1.1 to give it more altitude range. Version
1.1 was never published.
Jim Jennings created printed circuit boards for this design.
It is also 5 Volt only. As such it easy use in 1-Wire systems.

3) Version 2.0 -- http://www.davidbray.org/onewire/baro20.html
This design has improved resolution by adding a second required power
voltage -- 10 Volts. Two voltages regulators are incorporated in the
design to provide both 5 and 10 Volts. This means that the barometer
requires a minimum of 12 Volts input.
The resolution of V2.0 is more than 2 times that of V1.1a, depending on
desired barometric pressure range.
Jim Jennings also created printed circuit boards for this design.

Variations:
1) http://www.davidbray.org/onewire/baro2030.html
This web page discusses Version 3.0. Version 2.0 and 3.0 differ only in
the available printed circuit boards and the choice of components. This web
page describes this in detail.

2) http://www.simat.org.uk/barometer.html
Simon Atkin has designed another version and printed circuit board of
Version 2.0. This is available as a kit.

Summary:
Version 1.1a is 5 Volt only -- less resolution but easy to interface.
Version 2.0, Version 3.0 and Simon Atkins' Version differ only in choice
of components, and available printed circuit boards. All of these versions
are essentially the same and have the same stability.

Jim Jennings has printed circuit boards for V1.1a, V2.0, and V3.0. These
allow you to change resistor components for ones own desired altitude,
pressure range, etc. There is an Excel simulator to assist in resistor
choices for ones desires.

FYI:

The Synergy ANPC135 surplus MCX connector antenna cable DIRECTLY plugs into
the OCX connector on the BG Micro receivers. Snaps in firmly and stays in.
Go figure...

I don't have a way to power them up yet, but the antenna plugs in 'just
fine'. I'm also waiting for TAPR to respond with an interface card....and
have heard nothing except 'we got your order'.

A group buy (for the rest of the mob) may be a good idea. Unfortunately I
paid their surplus list price. The order arrived within a week.

Success.....of sorts.

Have a TAPR interface board that I managed to add a backup battery and 1PPS
circuit to, neatly strapped to one of the Oncore boards and a Synergy
Systems antenna. It now knows where it is, in spite of being only able to
see 3 birds to the south of my office--it does not like metal roofs!

Still having no luck getting it to switch to NEMA message mode with the
Motorola software. Any ideas?

Really need a nicer board from Simon, et. al. (hint, hint)

--Rich

[Michael Muniz]

Use VisualGPS http://www.visualgps.net/VisualGPS/default.htm as I could not
get the Motorola software to switch it to NEMA mode either...

Communicating with these oncore receivers is a bit tricky.
Actually it's a lot like 1-wire programming, you have to
send a command and a checksum. I wired the TTL serial pins
on the oncore directly to a microcontroller. A very simple
program send "@@Eq" followed by checksum 69 Xor 113 Xor 0.
This gets the receiver pushing data at me. The uC then
just forwards the data to the PC over another port. I did
this because I wanted to interface other devices too like
digital compasses and text displays. If you simply put a
MAX232 (plus capacitors) between the oncore TTL serial
pins and the PC serial port, it's the same drill, send
the motorola binary command to configure the receiver,
followed by the checksum. Aside from MAX232, DS275 would
probably do the trick too, with no external capacitors
and a nice and small 8-pin DIP.

The Oncore documentation is here:
http://www.motorola.com/ies/GPS/products/legacyproducts.html#download

Take a look at the commands in chaptersb 5 and 6
http://www.motorola.com/ies/GPS/download/gpsusersguide/gpsusersguidev5chap5.pdf
http://www.motorola.com/ies/GPS/download/gpsusersguide/gpsusersguidev5chap6.pdf

Ah yes, refreshing my memory, the @@eq command puts the
receiver in "ASCII Position Message" mode which is not
NMEA but gives a convenient text-based string of data
once per second (actually, the interval is selectable).
Some of you folks will want to look at the 1PPS commands.

So there are three GPS modes: motorola binary (gives you
tons of extra capabilities), NMEA mode (follows the NMEA
text string standard), and ASCII mode (simpler to deal
with than NMEA). All of these can be cofigured so the
receiver sends continuously (at selectable intervals) or
only when polled. And you'll see tons of command related
to time (1PPS and UTC etc) in the command list above.

In all cases its simple to program, send @@ followed by
the motorola command (Letter plus number combination),
followed by the checksum, followed by <CR><LF> or ASCII
10 and 13. Pick your mode and you're on the way.

The TTL serial pins are described in chapter 3. Pin 1
is transmit and pin 2 is receive. I have tried this all
different ways: with MAX232 to PC serial port, to a uC,
and all three modes: binary, NMEA, and ASCII mode. This
is a nice receiver! Mine has been collecting dust for a
while but its about to get fired up again.

For kicks, I used the oncore receiver as a Doug Tracker
for one full month, sending my position to a fixed
server over the ricochet wireless network. The oncore
was hooked up to an embedded PC on body ...

For those who wondered -- the antenna from Arnie Speer does work with
the Oncore receiver.

If we are going to design and build a better interface, what should it
do? One thought was to make it a USB device -- providing power and also
the serial connection. However, I couldn't find a really good chip to
fit. The Cypress EZUSB parts are expensive (AN2135 - $10), and the TI
parts (TUSB3410) are cheaper but don't have5V tolerant IO. Also, it is
unclear that there is a good solution to generating the 5V required by
the oncore unit. Maxim has a MAX5008 part that can provide 125mA while
the Oncore says that it can consume up to 200mA. I haven't actually
measured mine.

USB would be nice, even if it cost a few extra bucks. That way I could
use the single serial port in my laptop to run my new iCom PCR-1000 and
know exactly when NOAA-17 was passing over head :-)

Sounds good, what USB device driver can we use for this type of setup,
is there a generic / manufacturer one or do we need to write our own.

After some more research, I think that (for USB) this is the way to go:

AN2131SC with a serial EEPROM attached. [This allows the device to boot
without host intervention. The EEPROM can be programmed via the USB]
3.3V regulator
Ideally, there should be a power switch to shut off power to the GPS
module. Various MAX parts fit the bill.
BNC connector for antenna
Flashing LED for kicks

Parts cost under $20

Use standard Windows drivers. Use standard linux drivers. Use sample
Serial firmware from Cypress (or the firmware that ships as part of the
Linux kernel).

The only issue is how to handle the 1-pps signal in a sane way. My
feeling is that cunning use of the isochronous transfer modes could
help. With some care, it might be possible to get sub 100usec accuracy
through the USB path. The isochronous transfers happen every 1ms and so
the device could send the position of the 1-pps pulse relative to the
1ms frame boundaries.

I found a place on the 'net that was selling remaindered Xircom serial
USB adapters. It looks as those they contain the AN213x chip. I ordered
a couple of them, either to hack apart to connect to the GPS receiver,
or just to play with. See
http://www.centrix-intl.com/list.asp?CategoryID=9 and scroll down to
U1S25. They are $4 each. The shipping is a bit steep, so it pays to buy
a bunch. You also need the USB cables as well ($2 each).

*Warning* I have never looked inside one of these devices. My total
information was gleaned from the Linux kernel sources which use EzUSB
(trademark for AN213x) drivers to drive the Xircom PGS device.

Clay-

If your software can pry a "Position/Status/Data Message" out of your
(Motorola Oncore GT, yes?) GPS unit, it will tell you lots of good
info such as how many satellites are being tracked, date, time,
position, velocity, antenna current characteristics, etc. This is a
Motorola Binary Format message.

You can also use other commands to set date, time, position, etc.
manually to verify you're reading out these data correctly.

The specs say your unit should get a fix in 90-210 seconds from a
cold startup. Mine has been meeting that spec so long as the
antenna has a reasonably unobstructed view of the sky.

FWIW, I'm driving my Oncore from a Parallax Basic Stamp 2, and
developing algorithms for the creation of a PIC-based system that
will allow access of the GPS as just another 1-wire device.

Steve

and on CDROM. Starts rather basic and go to rather advanced topics in
almost 5000 pages. As a degree'd engineer (BSEE) I've found it a great
review for areas I haven't worked with in a while (in some cases a long
while). I simply downloaded all of the pdf's and the index.html file
and burned them onto a CD. It's about 57 Meg total and I think it's all

Go figure--

Now the silly Motorola software is switching modes, but its doing NEMA
messages at 9600 baud....which is fine for this computer, bad news for
APRS, I guess.

Interesting to wathc satillite signals drop off as they get north of my
office window (faces south) where the antenna is sitting on the sill.

I'll try visual gps later....

USB has my vote too!! I know that I'm always seeming to bump into the limit
of only having two built in serial ports to play with. As a matter of fact,
I found myself wondering if anybody makes an RS232/USB interface, but I
haven't spent any effort looking yet.

I have a USB to RS232 hub....USB in...2 USB out and 4 serial lines

I found a bunch of RS232/USB interfaces at my local Target store.
They were designed to interface a PDA to a PC but they behave
very generically. I'm using them as a 3rd (& 4th) COM port.
I haven't tried going to 5th and above yet. Mfr: Belkins.
Originally $30, but clearance priced at $8 each.

As far as I can make out, modern versions of windows have native support for
RS-232 converters. The only hassle is to write the .INF file that ties the
device code to the fact that it should use the usbser.sys driver (but there
are plenty of examples around).

If the AN213x part is used, then the firmware is downloaded from the windows
box at power up. I am unclear how to integrate this aspect. However, just
looking at how Keyspan do it for their dongles might well be informative.
See http://www.omnigroup.com/~wiml/soft/pic/keyspan.html for interesting
information.

What suprises me is that I couldn't find the code for loading the firmware
on the Cypress site.

Sounds good, what USB device driver can we use for this type of setup,
is there a generic / manufacturer one or do we need to write our own.

I have seen today the input for the OnCore interface board. While
interfacing it to USB on the PC definatly looks good I think that a serial
interface would be more universal (there exist RS232 to USB
convertors, also some people may be using older systems that don't have
USB).

For my particular application I would like to interface the
OnCore to the TINI. Seems that the best way to do this is via RS232.

Maybe the board design can be such that there is a basic minimum circuit
for communication with the OnCore and then components added for additional
features as needed.

Just my 2 cents worth.

[Tom Snyder]

Another vote for USB. After taking a quick look at this site:
www.delcom-eng.com the interface can be both serial and USB as one
still needs a MSX232 chip. The site is dedicated to "Add USB to your next
project".

I had a bit of a hassle finding the right coin cell holder, but butchered a
slightly bigger one onto the back of the TAPR card. I also added the logic
circuit for the 1PPS output and LED so I can tell when the receiver
is 'happy' and came up fully.

Yeah, its hard to beat their price for a reliable RS-232 interface and
switching 5v power supply. I'm been running mine from a standard 9-volt
battery for short periods, a Radio Shack universal adapter (wall-wart or
car-type) for longer periods.

The one thing that bugged me a bit about the TAPR board is that it is one-
sided, with no plated thru holes and no ground plane--that made mounting
the battery holder on the foil side a bit of a bear. it also was hard to
get it to solder, unlike the very nice boards Simon supplied!

I agree that RS-232 is reasonable for experimentation--I don't have a
laptop that does USB yet...and RS-232 is good for APRS systems as well.

Hm, self-tracking car would not be too hard with a few more spare
parts....<evil grin>

Give me inexpensive single sided boards over the virtues of the fancier
ones, when possible, even if it means soldering in a few links.

I have managed to figure out the placement for most of the components
without a schematic. Since this version of the board has only 8 resistors
it doesn't match any of the previous BP sensor schematics, even those that
are also supposed to be version 3. Can someone provide me with the values
for R1 to R8 so I can finish this up and attempt calibration?

OK - so I've got the TAPR interface, and managed to get Visual GPS to
get it sending NMEA data; and there's 4.9V on the antenna lead; but,
I've been waiting 30 minutes and still see only zeros in the position
and time data.

How long should I expect it to take to initialize; and what
troubleshooting can I do - my antenna is an EBay special, but was sold
as a 5V active antenna.

Thanks in advance!

May be a dumb question, but is your antenna inside or outside. The GPS
signal will not penetrate much in the way of walls or roofs.

The antenna's outside - next to the house, but with a pretty reasonable
'view'. In fact, it's right next to an old Delorme EarthMate that I'm
using as a clock reference - the EarthMate has been locked for months,
and only took about 30 minutes to lock when I first brought it up.

I'm gonna leave the antenna out overnight and see what happens.

OK - now I'm even MORE confused! I went back to the Motorola GPS
program, reset the baud rate to 9600, fed the GPS the almanac that came
with the program and set my position. Less than 1 minute later, it
acquired a satellite. I have NO idea why the initialization stuff I
did earlier didn't 'take'.

Anyone got any thoughts?

One of the things I had a spot of trouble with was being absolutely certain
all the pads on the chips were all theway down on the board. Sometimes
they will sit a bit high, and the chips will power up, but will not be seen
on the network.

Minimal amounts of well-flowed solder and enough flux seems to be the key
to getting them all the way down. I had to carefully heat and press two
cips down when they failed to talk on the net...

another critical item is, if you have parts grounded to a metal case, is to
laso fuse the ground lead from the battery. Use the same size fuse as you
put in the hot lead. This prevents the car from drawing excess current
from your ground lead through the case of your project enclosure if the
battery ground lead is loose on the car body.

Ground loops in a car are not really a problem as long as you are inside
the same car...and the battery leads are properly connected to the engine
block and chassis.

Just thought I'd let you know that I've got owis to

hub) is possible. I now do Analog to digital
converters, Switches(2407), Counters and Temperature
Sensors. If you want to have a bit of a play with it
go to:

www.sf.net/projects/owis

And get the code from cvs, sorry I haven't had time to
release and files yet. You'll also need the
XMLRPC-epi library to compile it. This is not for the
faint hearted yet, its almost beta. I've only tested
this on Red Hat 7.3.

There is one bug that I've found, when a client dies
mid request it takes out the server too.

[Arne Henriksen]

Hi David,

Just REMEMBER to read the INI-docs.htm, in the Barometer section:
There are 4 values in SENSORS.INI of importance for how WServer will do
things, with default values:
-------------------------------------------------------------------------------------------------------------
hiBar=30.7 Upper limit of range
loBar=28.7 Lower limit of range
Vhi=3.25 VAD that is output when HiBar is input to the
barometer
Vlow=1.25 VAD that is output when LoBar in input to the
barometer
-------------------------------------------------------------------------------------------------------------
As you see the Vhi value will default to 3.25, and this will/has cause(d)
some hair tearing regarding the V3 barometer, as you have to set it to a
considerably larger value to get a usable reading out of WServer.

If you have all of those to the same values as you calibrated your
barometer, THEN you can use the BaroMultiplier/BaroOffset to fine-adjust
things.

Regards,
Arne

I spent the long weekend diddling with my new hub and barometer and

range is too much. Is there a methodology for tweaking the server.ini
values to match the actual conditions? I have been reducing the
BaroMultiplier and then adjusting the BaroOffset to correct it back to the
nearby airport which is at the same elevation as I am. It has been a long,
slow process.

Hi Arne,

Yes, reading docs is good. I read them, but since I didn't do the
calibration myself I didn't realize our v3's are set up for 28.0/31.0 and
1.25/8.25. Rich pointed this out to me this morning. That will make a lot
of difference. Thanks for the reply.

Glad it worked out!

Hi Arne,

Yes, reading docs is good. I read them, but since I didn't do the
calibration myself I didn't realize our v3's are set up for 28.0/31.0 and
1.25/8.25. Rich pointed this out to me this morning. That will make a lot
of difference. Thanks for the reply.

Try keeping up to 4 older Volvos at a time and kkep them running
properly....

Currently '90 760 Turbo (178,000 mi)
'94 850 Sedan (140,000 mi)
'87 740 Sedan (120,000 mi)

Once Upon a time
'84 240 Sedan (190,000 mi) Still seen around town
'77 245 Wagon (85,000 mi) Still being driven by the guy that
bought it

They just nickle and dime you to death will silly stuff--like broken radio
antenna and other plastic, hard to get parts....

But, they are solid (stolid and boring) and safe for college kids...

Off subject but I'm still driving my Chevrolet 4X4 truck - 250,000+ miles,
dirven daily.

Rebuilt tranny installed June 2000
New engine installed December 2001

Body and suspension is great, interior needs work.

Since we are all showing off: Chevrolet S10 truck - 400,000+ miles,
driven like a dog daily.

Original engine.
Original tranny.

Runs like a scared rabbit. :)

<Grin> I need to super-glue the LaCrosse rain gauge down somewhere. I
noticed that it stopped recording sometime Sunday...turns out it was tipped
over by the wind sometime late at night....

I think I need to strap it to a brick or something....

It does not cut through insulation...

They need to be stripped just enough to go into the connector. It might
also be a good idea to twist the bare strands together to avoid stray bits
causing a short.

Unless they have changed the connectors it is self piecing when you compress
the center of the connector, no insulation needs to be stripped. I installed
my kit last April and the connectors were self piercing and the description
in the post matches what I had in my kit.

Hmmm not sure now, if I do push it in without stripping the wires and
they have changed can I pull the middle out again?

No we haven't changed the connectors, they are self piercing. They are rated

Rule of thumb: 1000 circular mils per amp....

you also need to consider length of wire. Best bet is use the biggest
multistrand wire you can fit into the holes on the board.

It depends on how far you're going and how much voltage you can afford to
drop in the wire. If you're staying within any reasonable size wire wrap
board, even #30 wire wrap wire is probably okay.œA isn't really all that
much; even if you're going several yards, #22 or so is probably fine, even
#26 phone wire would handle it okay.

Rather than guessing, let's do the math. Presuming your display will probably
tolerate ±10%, and your supply is really 12V, we can afford to drop about a
volt in the wire (I prefer to be a bit conservative). Remember that there's a
drop both going and coming, so count the total length of both power and
ground wire. At œA and allowing for œV drop in each wire, we can go a number
of feet which produces 1 ohm. #30 is listed in the wire table I'm using as
105 ohms per 1000', so that would work out to about 10'. #26 is listed as 42
ohms per 1000', so about 24' there. #20 is 10 ohms per 1000', so now you can
go about 100'. And if you want a really "adequate" wire, #0000 wire is 50
milliohms por 1000', so is good for around 20,000'! I'm guessing you don't
need quite that far, though.....

What the hub buys you is the ability to isolate runs of cable from each
other if your one-wire setup is in a 'star' configuration. Some have found
that running one-wire sensors in other than a single line of cable causes
ringing, bad reflections, and mismatches when the sensors are read, and
causes vewry weird things to happen because of signals literally 'bouncing'
back and forth and cancelling each other out.

The hub allows you to connect multiple sensors in a single line just like
before, but allows software to switch the data signals to each sensor group
on and off as it reads them. It also makes 5 and 12 volt power
distribution much simpler.

My example may be sort of typical:

The hub is located in a wiring closet in the basement of the house. The
computer is currently 30 feet away in my office. It has the adapter and
uses Arnie's software. It has a honking big Radio Shack 12volt 1 amp wall
wart providing power to it and the attached devices.

The barometer is directly connected to the hub in the same closet on one
port. Not more than 1 foot of wire. It needs 12v to operate

The V2 wind instrument and a solar sensor is off another port, 55 feet up
the side of the house, with a total cable run of about 80 feet.

My raingage and humidity sensor is in a small shelter device in the back
yard, about 10 feet above ground on a garden structure, connected to yet
another port with about 60 feet of wire. The humidity sensor requires 12v
DC to operate, and the enclosure also includes a small 12v fan to assure
the air does not get overheated by the sun. Next project is a simple fan
speed controller board that turns it on only when sun is out.

There is a lightning sensor on the side of the house at about 30 from the
hub on yet another port.

I plan a string or two of temperature and humidity sensors inside the house
but have no idea where and how long that string will be.

When I tried to hook up all this in a star setup without a hub, I got the
typical sensor and microlan errors, and it was basically unusable. The hub
switches the legs around so that the computer and adapter basically see
only one run of wire to talk to, thus eliminating the signal problems.

In many cases, the hub is the most cost-effective way to wire these systems
if they are 'scattered' all over the place. It also makes it easy to use
standard CAT-5 internet wiring and patch panels. All my sensors are wired
to a Leviton structured wiring patch panel in the wiring closet, and
interconnects to the hub are via standard patch cables. Cuts the clutter
considerably.

There has also been some discussion on the group about using the hub with
Chris Fox's 'link' device to reduce RFI caused by the one-wire signals from
the current adapter having lots of 'sharp' edges. I have not gotten that
far yet.

Others may chime in at any time. SO far, the hub was a great improvement
over trying to get a random 'star' configuration to work at all.

Its not a problem putting 6-position connectors on the cable...
Just use the pair that is most tightly twisted for data--usually the white-
blue pair.

There is a version of CAT-5 cable that is rated for outdoor use, it can be
found at Home Depot or other home stores (sometimes).

If you cant find that, shield the cable vrom sunlight and it will be find.
Run it in conduit or something opaque.

I've seen that weird behaviour, but for the life of me I can't remember if
I had a way around it. The viewer does weird things with the switches...I
think it's NORMAL behaviour.

Try plugging a known device into the UNSWITCHED port and see if that keeps
the devices showing.

I do know Arnie's software (which I run) is just fine with it acting like
that. His start-up process first finds and identifies the switches, then
tests each switch leg for devices to build a network list in the file.

It may be an unterminated branch problem or something like that. I tested
all the ones I built by sequentioally plugging a known device into each
switched port and testing to be sure that known device appeared and
disappeared as I manually switched ports. If a Hub did that, it worked
fine in the real world. I know I left the viewer 'switch window' I was
working with up on the desktop whilst I tested the hub.

I bet you had as much fun as I did soldering in the tiny 3 terminal diodes
on the backside of the board! BTW, if you drop one, a magnet is about the
only way to find it--their leads will stick to a magnet. (I dropped 2 of
them on a dark grey carpet one time....)

If you are using the temperature sensor in the wind vane, there is not much
you can do.

Many folk on this list have gone to using a separate temp sensor located in
a variety of commercial or home-made pagoda or other enclosures. Browse
the archive for some of the ideas.

My system uses a set of parts salvaged from metal lawn lights, a
temperature/humidity board from Jim Jennings, and a small fan to move air
through it and reduce heating effects. No pictures as yet, unfortunately.
The basic idea was to use one light base, several sections to form the
louvers, and two solid top caps to keep the rain off. I used a big drill
bit in a drill press to mill the posts down to a suitable height and used
threaded rod and wing nuts to hold the sections together. The sensor board
is mounted inside, with a fibreglass window screen cylinder glued inside
the louvers to keep bugs out. I'm working on a solar-power rig to run the
circulator fan at present.

Others have used platic bowls, sheet aluminum, or commercial pagodas for
the same purpose.

The sensor in the wind vane does give you a measure of solar intensity
during the day and/or radiation cooling effects at night, so its not all
that bad. Just not too useful for accurate outside air temps.

Scott,
Here are some pictures of my temp pagoda I built out
of plastic bowls I bought at Wal Mart. I used
threadall(a long bolt with threads from one end to the
other). I bought some plastic tubing that would slide
over the threadall for the spacing between th bowls.
All the bowls have a hole in then except for the top
and bottom bowl. My humidity and temperature sensors
are center mounted in the holes in the bowls. This
setup has worked perfectly for over 2 years. Holler
if you have any questions.

I did something VERY similar out of white plastic flower pots, and
two
saucers for the same - which had 3 advantages

1) 3 drain (read vent) holes in the bottom of each
2) 2 holes the fit all thread perfectly
3)COST - they were something like 60 cents each!

The NICE thing about the way they were molded was that if you rotated
them 180 degs around the all thread, the holes in each layer don't
line up on the bottoms, so no water gets in, but the air still
convects

Be wary of strong drink.
It can make you shoot at tax collectors -- and miss.

One other option is to buy one of those multi-tiered decorative yard
lights ("malibu light") and paint it white. I used a metal one and cut
the spacers between the tiers to shorten it a bit. It works great.
Cost was about $20. I can post pictures if anyone's interested.

Is there a pagoda modification that can be done to the station? When the sun
is shining on my station the temp reads ~10 degrees higher than what it
should be.

Or is there something else I could do to compensate for the sun effect?

Very nice, Gregory. And much like mine too. I like your mounting system. I
put holes in all of mine except the top and the bottom, as you did and then
was surprised later to learn from the "official" pagoda design sights that
the upper ones should not have a hole in them. The idea is to have air
cooled layers above the measuring device, not a chimney affect.

Sorry, I have lost the link to the site.

[Doug Brance]

Tthe reason my WS is still on my bench is the pagoda, or lack of same.
What is the consensus regarding chimney effect?
First how can any passive device collect cool air above the sensor? I've
been playing with several designs that are basically long, vertical,
insulated, tubes with sensors near the bottom. It seems to me that if
the outside surface of the top of the tube, well above the sensors, is
dark it will, when sunny, heat the top causing ambient air to enter the
bottom. But the post below suggests that the "official" site says no
chimney. What say the group?

Thanks,

Doug

Hi David.

It seems as it 'arrived' around 3/19/2002 - maybe I messed up something
back then, and you upgraded at 7/28/2003 and got it.
Sorry I should have spotted it earlier, but I'm barely looking at these
data myself...

I'll see what I can do about it. :-)

Regards,
Arne

Just found that I must have changed versions of the software, it was the
day that I added the barometer. It also now records the data in the file
identified by the day of the readings, instead of the next day. That part I
like, Arne! Its the problem of the missing tabs that makes me cry out in
pain. I wrote a macro for my programmers editor to replace the space with a
tab and move back and down one for the columns that don't have the tabs but
it still takes a lot of watching what you are doing to get it right.

Thanks, Arne, I would appreciate it. Trying to import into a spread sheet

Doug,

==>First how can any passive device collect cool air above the sensor?

The idea is not to have the sensor track the cooled air above, but to cool
the pagoda layers above to reduce radiated heating (radiated from the
enclosure via the sun) to the sensor below. Your idea of a self circulating
air system sounds interesting. I don't think I've heard that idea before --
sure sounds like it could work! The key would be in trying to insulate the
lower section well enough I would think. And how do you keep rain & debris
out of it (or do you care about that ...maybe not)?

the outside surface of the top of the tube, well above the sensors, is

chimney. What say the group?

A simple cover/lid that allows plenty of air to escape, but allows no

says to avoid using a chimney.

Doug,

I guess I don't know either. This seems like a workable idea to me - at
least on a sunny day. I was just trying to decide if there might be some
undesirable effects under certain circumstances. Like at night - could the
tube somehow be artificially cooler than the air temperature and cause false
low readings - something like the effects we see with the OWW "sealed"
anemometer enclosure temperature readings on a clear night?

For a interesting paper related to the subject try:

http://www.geo.uni.lodz.pl/~icuc5/text/P_6_5.pdf

I've add this and a couple of other links to the
www.1wire.org site under the reference materials
weather, Stevenson Screens, Pagoda and other
screen forms

I'll keep adding stuff as I get time...

Hope this helps... The use of foil is very interesting...

I did not get decent temp readings until I built my own stevenson screen -
the difference was quite marked..
Have a look at a temp graph displaying the differences
http://www.hillsrain.com/Weather_Station/Events/Events08.htm#28-02-03
More details including pics of my screen can be seen at
http://www.hillsrain.com/Default.htm
It is well worth building one and not difficult.

Unless I misread the document it compared the Stevenson to
other common types of "home built" screens. I thought it
interesting that the Pagoda seemed to come out quite well.

In fact while I've been following this thread I had an idea
to combine the designs of a chimney style pagoda and a fan
ventilated enclosure. To this end I have obtained a solar
powered pagoda style light . It is made of stainless steel,
has the solar power unit on the top and has 4 sets of pagoda
fins. I intended to replace the metail fins (which are too
short) with a set of bowls or similar and use the solar
power to run a small fan at the base. This way it is
ventilated during the day, but not at night. To avoid any
sort of "wind chill" factor creeping in I am considering
using a 6 or 12 volt fan at the end of the 3 v solar power
supply. In this way I'm hoping that the fan will run just
enough to move the air in the chimney without introducing
any other errors.
One of the first things I have found is that stailess steel
body appears to heat up in the sun. I imagined its relective
surface would prevent that. So I will probably paint the
whole thing white to start with.

Well thats the theory anyway. I'll photgraph and document
the project as I go and publish some results.

Cheers
Colin.

Tim,

I would love to take a look at your screen but I can't find on your site,
just a page in the photo album showing the effects of it. Could you give us
a hint please?

BTW, this weekend I helped my wife set up her new green house and of course
she wanted me to add temperature monitoring to it. I placed a number of
devices there, even one with a little pagoda of sorts and was amazed to see
how all over the map the readings were both in full sun and at night under
a clear sky. I'm still working on getting something useful. Right now they
all read about the same since it is raining but the ones more sensitive to
solar radiation are still climbing a bit above the more neutral ones.

Hi David and all,
It is early morning now and I will be working late tonight, but as soon as I
get a chance I will make a page with some instructions (the spreadsheet is
still a little raw) and the file for download. There seems to have been a
bit more than one person interested so it will be better for all if it is
available this way!

David I aoplogise, I stuffed up the second link with the pics.. OOPS.
http://www.hillsrain.com is the home page address. The website loads in
frames, but if you want to shortcut directly to the stevenson screen page
it can be seen at
http://www.hillsrain.com/Weather_Station/info/weather_station.htm ( or use
the site search ) bear in mind that this is without the top navigation
frame. Clicking on the "home" link at the bottom of this (and every other)
page will return you the "frames" page. I should never have used frames all
those years ago.. Oh well.

Cheers,
Tim

Inanimate objects (i.e. temp sensors) do not experience a wind chill effect. Air movement past the (dry) sensor will bring it to ambient temperature faster but will not produce any cooling below that. With the fan at the bottom of the pagoda the air flow should be from the top down. You want virgin air to move past you aspirated temp sensor. With the fan at the bottom and blowing up past the sensor the air column may be minutely heated by the fan motor. Or locate the fan motor at the top and have it pull air up and out.

Pat,
Thanks for the tips, I thought something similar so far as pulling the air
from the top down goes. My reasoning was slightly different in that I was
worried about pulling in convecting air off the roof that the pagoda will
sit above (I'm intending it be about 3 metres up a pole). I guess this
could be a problem either way so I may end up painting the section of roof
white in the immediate area around the weather gear (luckily its the garage
roof !).

Thanks - Colin.

Inanimate objects (i.e. temp sensors) do not experience a wind chill effect.
Air movement past the (dry) sensor will bring it to ambient temperature
faster but will not produce any cooling below that. With the fan at the
bottom of the pagoda the air flow should be from the top down. You want
virgin air to move past you aspirated temp sensor. With the fan at the
bottom and blowing up past the sensor the air column may be minutely heated
by the fan motor. Or locate the fan motor at the top and have it pull air up
and out.

Actually, they were referred to as selsyns or syncros. A three phase
stator winding in each device interconnected to the other one, and a single
phase AC rotor hooked to either 110v 60 cycle power or 400 cycle power.
When you turned the one end, the rotor on the other end turned to match
position. Strictly an analog device, used to this day in shipboard
navigation systems including gyros. Were very highly developed technology,
and included some fascinating techniques to ampligy and repeat signals with
and without vacuum tube amplifiers. They were also used in radar antennas
and scopes to provide a rotating sweep. Lots of mechanical parts involved
as well. Some fire control systems on battleships were filled with them
and a lot of cams to do the computations to aim the guns.

Yep, also an OF
