That is a good point, the best plan may just be to put an antenna on a pole
and run the lead inside.

I don't know anything about the equipment in that area.

Re: [PLUG] Backup RPi SD card

2017-04-13 Thread Chuck Hast

Well, if you have 1-2 bars a directional antenna will give you some gain,
If you can add 5 db to that you should be pretty good. Wonder what they
are using out there? I have an app that shows me which band the radio
is working, I will have to look and see what it is. If you look at
directional
cellular antennas there are quite a few. As to the device, I have been
looking
at several devices all of them are some sort of cell modem, I am trying to
find one that uses PoE and is in a weather proof case. Having lived in
FL I know what salt air is all about. In Tampa anything outside had a life
of about 2 years if it was any of the common metals. I.e. Aluminium, most
steel, and iron. About the only thing that had a reasonable life was SS.

Back on the antenna thing, yes, if you can add some elevation to it even
better. Vegetation is evil. the NW is no better than tropical rain forest
and
in some cases worse, the needles on some of the conifers are 1/2 and 1/4
wave length at some of the common used frequencies and those needles
really suck up the RF. I had a similar situation in S. New Jersey, those
needles were near enough to 800Mhz wavelength to cause major attenuation.
1/4 wave is about 9.8cm, which is about the same length as those pine
needles
in S. New Jersey woods.

Gotta get to bed, am in San Diego tonight gotta go to LA (yetch) tomorrow.
Flew in to LAX from PDX this morning drove down to SAN. Did a job now
back to LA for another one. Then home, the only thing I am going to miss
from here is the sun...

I usually got 1-2 bars of signal strength on my AT&T phone. I didn't try
other carriers. I suspect it would be much higher with just a little
elevation, but he's right on the coast so weather protection is extra
important. Probably more important than the device used - it could just be
a phone with tethering enabled. But the salt gets into everything and
wrecks and ruins so fast.

I wish he was a neighbor, sadly he's a 6 hour drive away (Gold Beach), so I
have to be extra careful about solutions I set up out there.

Re: [PLUG] Backup RPi SD card

2017-04-12 Thread Chuck Hast

My first attempt was to use Part 15 radios to do the link, I have a good
location
in Longview that can see the ridge very well and of course the other way
from
the ridge I can see the location just fine, it is getting from the ridge
down to
my place that is a pain. Too much trees and tall buggers at that. If I can
get
a cellular link from the high part of the property I just as well go that
way and
be done with it as I will not need to see what neighbor will host the
repeater
for the part 15 (wifi) system.

I have done a lot of part 15 links you can take an old satellite dish and
build
a great very directional antenna with one, has great gain, and very good
front
to back. Indeed many times the link will run over distances that the radios
will
not carry due to speed of light issues. I have even used lasers for some of
that
stuff (not in our area obviously ) there are all kinds of ways to do it, at
this
point the AT&T offering is looking better and better.

I have used Ubiquity radios in a lot of places for the price they are good
radios.

Wes, the neighbor that has the connectivity issues, do they have AT&T
coverage on their property? If so I would certainly look into that offering.

Can you maybe setup something yourself with some ubiquity radios? You

If you do this, I would be very interested in what equipment you go with
and the results. I have a friend who lives in a rural area currently on
dial-up because of how awful hughesnet is. I drove around his yard looking
for the best cell reception and got myself stuck. luckily it was in a spot
that worked!

Re: [PLUG] Backup RPi SD card

2017-04-11 Thread Chuck Hast

Yes, it is truly a sad solution, but where I live it is the only one. I
often tell people
that it is a good thing that the agriculture people who feed us do not
treat us
like Hughesnet treats them, we would all starve.

If I get the job I am trying for, I will be moving, Indeed may spend part
of my
time in Costa Rica, wife is down there dealing with family things father in
law
wants us to move in his place, he is now by himself.  I would get fibre at
his
home if I do so. All depends on the job I get here. I am working on a field
service job that allows me to live anywhere near a airport on this side of
the
planet.

Re: [PLUG] Backup RPi SD card

2017-04-11 Thread Chuck Hast

Oh, ok. Yes, I am looking at getting a WX proof modem, something that uses
PoE, and directional antennas, put a shack up on the ridge and use solar or
wind to keep it powered and run the link down to the house using some fibre.

Actually put up some sort of tower and mount the whole thing in a WX proof
box, put the radio and antenna up on top of the tower, and hang the box at
the bottom. The power and media converter will be in that box, perhaps an-
other box for the batteries below it. Keep the out gas out of the equipment
box.

If I can get the AT&T offer of 250GB for $60/mo I will be very happy as I am
getting taken to the cleaners with Hughesnet.

can pick up enough EMF to do it. Does not take much. A place where I worked
in Tampa, we had lightning hit the flag pole out front of the building every
parallel port that had a printer or scanner plugged into it was dead, and
the
printer/scanner too.

Then there is something called "Super Lightning", I have seen it several
times
in Costa Rica and a few times in Tampa, when that strikes all electronics is
DOA for quite a radius out from the strike point. Case in point, I worked
for
Del Monte Fresh Fruit in Costa Rica. In the pineapple production area they
had just finished building the new office (they were in the process of
moving
pineapple production from Hawaii to Costa Rica) Everyone had moved into
the new office, they had all of their calculators computers and a new PBS
(AT&T box) just installed, indeed the pbx had been brought on line the day
before the incident.  There was a free standing tower out behind the
building
it was adorned with antennas for the radio system. The evening of the day
after the pbx going on line there was a bad thunderstorm. Very bad for
Buenos
Aires De Osa which has lightning so active that you can set and read at
night
and never stop during some of those storms. The way the wet Pacific air goes
up against the mountains in that region causes some real impressive storms
After the main storm subsided, there was the high outflow probably some
where at 35-40K feet. There was a sudden very intense flash and thunder
that was heard for many many miles away. That stroke came out of that
high outflow. NOTHING electrical or electronic was serviceable. They even
had to pull new mains power in the building. After that we installed a
device
that was on a tall pole, it looked like a bicycle wheel on its side, there
was
a spike of radio active material that stuck up above it. It was called an
"Ionocaptor" after a normal thunderstorm you could walk up to the pole and
put your hand on it. It would be quite warm to the touch. But we never had
anymore lightning strikes on anything but that pole.

Had another superbolt that hit on top of the Irazu Volcano, there are all
kinds
of radio facilities up there, same situation it came out of the high
altitude
outflow of a dying TRW. Probably same altitude about 35-40K feet. It took
out just about everything up on the summit of the volcano. Several TV trans-
mitters, and loads of radio gear, we all had to make a trek up there to fix
stuff. I saw that one Indeed I just happened to be looking at the summit of
the volcano when it hit San Jose CR is about 21 Km from the summit line
of sight. The flash was incredible and the thunder appeared to come from
everywhere. I knew as soon as I saw it that we were in for a long night.

Yes in a lot of places there they put wire in the walls, 1 earthquake, 2.
EMP. I have seen EMP blow holes in concrete walls (Ch 6 TV relay
transmitter site Cerro La Muerte Costa Rica) at that same tower lightning
hit, went down the wire run for the station dog and burned the tail off of
the dog. that dog as soon as HE heard thunder was off under the power
plant in the main building. They did not keep him on the run anymore
either. By way the dog died of a heart attack from fear from a direct hit on
the TV tower a couple of years later.

I can tell you some good stories about lightning... Lived in two very active
places, but with proper protection, it is a light show never to be missed.
BUT, Respect it and follow the rules and you will enjoy many a light show
in your life, disregard it once and it may well be your last time.

At work we often do external (outdoor) runs for point to point wireless 
bridges between buildings. The masts and AP's are both grounded, as well 
as the ethernet cables with inline ethernet ground adapters. They look 
like regular ethernet couplers, but they have a ground wire coming out 
of the adapter.

Tom,

   Are you referring to the inhabitants of Edwin A. Abbott's 1884 book? We
read that in junior high math class. A wonderful read!

Wow EMP was so bad there that >300ft indoors caused voltages high enough
to fry NICs? I can't imagine that bad. Did people build Faraday cage
servers rooms in Costa Rica?

I have a similar problem with people in rural flatland having their
canopy SMs fried during storms every month or so.

What are the best options for EMP (caused by lightning) proofing your
home networks? Put ferrite cores on all the cables and grounded Ethernet
lighting suppressors on external runs? Also is it a bad idea to put your
computers on the common ground rather than a dedicated ground?

 If your RPi consumes close to or more than the charging current max 2A

Re: [PLUG] Backup RPi SD card

2017-04-10 Thread Chuck Hast

Are you talking about ESD or physically protecting the device? The remote
sensors are wireless so a lightning strike would take them out but probably
not do much to the rest of it unless it comes through the 110v line, or the
EMP
was too high, in that case there just is not much you can do about the EMP,
it is cheaper to replace the RPi and console that block for the EMP. I used
to
live in lightning prone areas, Costa Rica and Tampa, FL. I have seen my fair
share of lightning damage, one thing I learned was to run all long network
runs as fiber rather than Cat5/6. No issues with EMP with the fiber.

The console and RPi are inside the home so they are protected.

Sorry I should have got  back on and told you I found it, but the charge
rate
is only 1.5 amp, the other unit is 2.0 amp. The RPi doing the WeeWx stuff
pulls data every 60 seconds, writes to the DB and then sends it out to WU,
CWOP and Findu.com. When it does that it pulls a wee bit more current
that usual. So I am going to give the other unit a try as I have the PSU for
it. I will also power the Acurite console off of it.  If this works I have
a whole
boat load of places I am going to do that trick. Indeed if we do not move
out
of this place, I am going to put an RPi up on the  ridge above the house
with
a AT&T LTE modem on it, AT&T has an offer of 250GB/mo @ $60/mo or 500
GB/mo @ $100/mo. They just came out with the offer last month, it is
directed
at some states back east, but people are calling and getting the offering
every-
where they have put in LTE. At this time I have 50GB @ $110/mo with Hughes
net, and they suck royally. So I can put an RPi up on the ridge and run
about
500ft of fibre down to the house let the RPi handle the cell modem and get
rid of Hughesnet. Whattavampire they are. That one I will power with the
"kludge" as it will be a much better option there. May even try some solar
to see how much the batteries will keep up that way. Use an RPi to monitor
that too.

If I get the job I am angling for I will not need to worry about it, but I
can
always find something for an RPi to do.

Follow the second link, scroll down to product description about half
way through the page, and check the Duo-Charge Section:
 Product description

 








  












  

   

  

  



 Offer Type:19200mAH

  
  


  

  




 
   
 

 
  
 
   

 




TeckNet PowerTitan T2 19200mAH External Battery:
Save time when charging! 

.
.
.
Duo-Charge:
The Duo-Charge function enables charging of the PowerTitan while it
recharges a connected device such as an iPhone or iPad.
 ...
Besides the battery capacity, there does not seem to be functional
difference between the chargers. Either of them should keep mostly idle
RPi running for at close to a day. I have 6500mAh USB charger running
RPi + PWM hat + WiFi dongle + a few sensors on a robot cart for about 8
-9-hours straight. The Pi lasts much longer than the other battery pack
feeding the motors.
I should have mentioned it in my original post, I thought that it is
obvious:
If your RPi consumes close to or more than the charging current max 2A
(depending on your actual power supply) - about 10% to power the
charger = ~1800mA --> your battery pack will not recharge after the
outage. In such case you would have to come up with different UPS
solution.
Best luck, Tomas

Nat,
I have a kludge system that i am going to use until the passthrough charger/
battery arrives. It is ugly and being a kludge it is just a gell cell and a
power
supply, the battery is floating on the PSU. On power loss it picks up the
load
on the USB ports.

Tomas,
The second selection looks more like what I am looking for but the first one
will certainly work. But I do not see mention of pass through charging or
charge while charging.

Went ahead and bought the first selection.

I use something like that second battery to power my pi, it's just a cell
phone charger, I'm not sure what running it while plugged in does to it's
life.   One could put it on a timer so the power cuts, it drains the
battery for a while, then charges back up if that was advantageous for
battery life...

Based on recommendation from this guy: 
http://raspi-ups.appspot.com/en/index.jsp He used older model which is
no longer available.
I wonder how smart is the circuit in avoiding the charge/discharge
battery cycles when the power is on - it relates to the battery life.

The RPi Jessie install already does that, as I pointed out to Tomas, there
is
/boot and there is /, all under / is an ext4 fs.

I know what files I really need to keep so perhaps the best thing is just to
back those up and keep a ready card with the whole thing setup minus the
files that need to be from the backup.

The drive has two partitions on it /boot and /.  /boot is a vfat, the rest
of
it is ext4. I supposed that I could stop the service (weather data capture)
back up the files that are critical to the weather station.After the back up
is done start the service again. Maybe store them on a jump drive and
after the station service is back up and running ship them off to the

I will keep the back ups in. I figure that I could do the back up in the wee

All I really need for recovery is the WeeWx db file, WeeWx config file,
skins
file and the nginx configuration. I could actually keep a separate image and
just insert the latest files and quickly swap out the bad SD card. That
should
take care of it.

I should be able to automate the OS configuration, so that I just run a
script
it looks for the SD card, installs the OS makes sure that the parameters
that
I set manually on installation are set correctly, probably can automate the
whole process.

I have been looking for a battery pack that will allow me to let it float
on the
powersupply until power goes away, then it takes over. So far all of them
that
I have looked at will not switch between charge/float/discharge. I have seen
a couple that plug into the pin field on the RPi, but I am trying to keep
the
case clean. I have built up a power supply with a battery on it, and a heavy
duty USB dual port power cartridge that supplies the power I need for the
RPi and the WX station console. It is kind of big, I am certainly looking
for
one of the power pack batteries that does not care if it is being charged or
not.

Yes it confirmed most of what I was already suspecting. Now if I can just
find a nice clean battery pack that meets the above requirement.

Re: [PLUG] Backup RPi SD card

2017-04-08 Thread Thomas Groman

You could try separating your /boot to a vfat partition of it's own and
putting everything else on a

partition formatted with a file system that support live backups such as
XFS. Of course your

kernel would have to have support for this so if the Raspberrypi OS your
using doesn't you

would need to compile it in.

Re: [PLUG] Backup RPi SD card

2017-04-08 Thread Tom

dd nor rsync alone will not be able to do full backup of running
computer (RPi).
The best course of action is to separate the OS from your data -
whatever your RPi is normally writing - then backup each separately.
  * When you separate the data, you could even store it off the RPi
avoiding need for local data backups on RPi altogether.
  * If you want to keep the data on RPi, you could back it up by rsync
to separate media (USB) or a network storage
  * You cannot back up the OS while you are using it - that is why this
is normally done on a separate computer. It is easier and faster than
booting your RPi from USB or network and then doing the backup.
  * Perhaps the OS does not need to be backed up often or not at all as
you could simply create separate OS image, even on another SD card
attached to your Pi.
  * Your backup target/media could be another SD card connected to RPi
in a SD card reader, that way you could just swap the cards 
Thinking outside of a box - perhaps you need little UPS for your Pi to
avoid regular data corruption altogether. There are some USB charging
batteries which can be charged and used both at the same time (most can
be either charged or used, not both).  Modest battery could keep your
Pi running for hours.
I hope that this is pointing you in the right direction to your
particular circumstances.

[PLUG] Backup RPi SD card

2017-04-08 Thread Chuck Hast

Folks,
I have been looking to setup a backup of a particular RPi that has a
tendency
to corrupt the sd card due to read/write activity during a power loss.

What I want to do is backup the whole image off of the unit to another
machine.

I know how to use dd to create an image of the card. But I would like for
it to
ship it off to another machine so in the event of a corrupt image I can
just to
pull the last good one and put it on a SD card and press on.

I see a lot of recommendations, using dd and rsync but most of them in one
form or another either require you remove the SD card and put it in another
machine or you do not get all of the files you need. So I figure that if I
can just
say at about 2 a.m. start the process and let it capture the image as a
snap-
shot things will be good. But I want the image to be created on another
machine
