So far so good, good enough for posters. De-ionised water for ironing
(without added pong). Chose 1:1 dilution, light cyan is good perhaps 2
water to 1 ink next time. Light Magenta is Trump colour for some odd
reason, but can live with that as only poster graphics and text.

I have a La Crosse Time-Temperature device that I picked up at a garage
sale about a year ago. It had a badly corroded battery compartment,
which I got cleaned up, at which point the thing started working.
 
Recently, the display (it's one of those "big number" 7-bar LCDs) has
gone quite dim when viewed head-on, but is plenty contrasty viewed at a
large vertical angle. It did not have this problem when I first got it.
 
I know the most likely reason for that is a weak battery, but the cells
checked out at about 1.5 V and replacing them made no difference.
 
La Crosse claims to have no schematics or other technical data at all
("the clock is made entirely in China").
 
Devices often have a "contrast" adjustment which changes some bias on
the LCD and alters the best viewing angle, but this particular unit does
not offer that as a user adjustment.
 
Is there some way that I can identify the particular connection to the
LCD which provides this bias? If I could find it, I bet I could hack it.
 
thx

Take another look inside the device. Battery spew tends to migrate away from the point of egress, and it might not be visible. A tiny bit of stray conductance could throw the display off. The board might benefit from a good soak.

I suspect this effect is due to multiplexing and an effective small
intermittent DC bias , from overlaps, that somehow builds up a charge
that upsets the LC

Elsewhere in this thread, you mumbled something about your internet
bill being part of your telephone bill. That means your ISP is
probably AT&T (also known as the evil empire). Lots of potential
problems, some of which I fix on a regular basis for customers. I
don't want to get into a troubleshooting exercise right now, but
basically, connect to the web server used to configure your
unspecified model DSL modem, and grab some numbers. If you have a
separate router, you may need to temporarily plug your computah
directly into your modem. What you want are the SNR and Line Level
numbers:
<http://www.dslreports.com/faq/16220>
This will tell you if you have too much copper between the CO or RT
and your unspecified model DSL modem, or if your unspecified model DSL
modem is operating at the limits of its capabilities. Or, the modem
could just be too old, has bulging capacitors inside, or is not made
for ADSL2+. Also, check the error rates if available. A few data
errors are normal, but anything over about 10% of the total traffic in
each direction is an indication of a problem.

No, it doesn't mean that I'm advocating your departure from s.e.r. It
means that Reddit would not tolerate such off topic questions,
discussions, and rants. You would be directed to a DSL related forum
on Reddit, where you might obtain a more reasonable answer. Unless
you keep your questions and replies on topic (and non-political), your
comments would probably be disappeared into /dev/null. In other
words, topic drift, rambling commentaries, and political rants are not
tolerated.
 
I haven't made an accurate count, but my guess(tm) is only about 25%
of the postings to s.e.r. are about electronic repair, which is much
better than s.e.d, which is probably 5% on topic.

You can call me a cheapskate or whatever you want but I can use a couple of people's credit cards, but I have a problem paying for what used to be free. I was an AOL sucker for a while. The most expensive end user ISP all the sudde drops Useet access, then they drop your webspace, where I used to have a couple of pages.

We wasn't nor had he ever been to Italy, but someone tried to use his card there. It was of course still in his wallet.
 
Apparently somewhere he used it, the clerk or someone got ahold of the numbers. I am not sure, but I am starting to think that online transactions are safer because quite possibly your numbers are never read by human eyes.
 
But really, paying for something that should be included is something I try to avoid. Walk into a tire shop now and ask them how much extra for the air, seriously.

Evil empire is right, and in fact that is why we use cellular for all long distance. And they are not an evil empire, they are a monster from hell. Got chopped up by the Sherman anti-trust act decades ago and just grew up bigger. All that really happened was a bunch of lawyers got richer.
 
The MODEM was just changed in the last year or so. It is impractical to go look right now but luckily I had the manual on this laptop. It is a Pace 4111N.
 
>"If it helps, I prefer to be more diplomatic when I'm being insulting.

Well if you did want me gone to most liely would not be offering advice on me keeping my access, which I do appreciate. However I do question everything. Later I will seek out your tools and bring back whatever SNL numbers or whatever, but I doubt that is the problem.
 
Reason being is that all other internet access is just fine, and I know how to coax it to reload rather than just rereading a page from the cache. This only affects Usenet, and actually I couldn't get it for abiout a month. I called ATT and the guy didn't even know what Usenet is, so I explained it.
 
Then, as it does now, it seems to just fix itself. Sometimes IE seems to connect better but at times I get the same errors. When it was down for a while I couldn't get Thunderbird to conect reliably, and by the time it did it seemed like Google did as well.
 
I'll get whatever numbers I can, in the meantime, the install is thus - the telco wire to the MODEM comes directly off the interface box on the side of the house. All other things on the line have filters. (a few newer things don't seem to need filters anymore, but they gotem anyway)
 
The master PC is a MAC and something I would rather not touch if possible. It has the typical RJ-45, as does the upstairs PC which is pretty new, Win 8.1 I think. My downstairs PC is offline right now because of a damaged CAT5 cable that is getting new ends crimped on. Hopefuilly that will be up by Friday. It is a 75 footer. Hopefully it works because I like having internet by the bench. The PC I am on now is the only one on wireless. However, when Usenet was down on this, the downstairs PC was still connected and had the same problem. So I doubt it is a problem with the wireless itself.
 
Now when I go to do this connection quality test, do I specify where to look ? Like would I have to point it to Usenet ? I have learned a few things aboutt he internet but obviously not enough, but any weak link in the chain from here to damnear Timbuktu could be causing this problem. Like there used to be a website called like "speedtest" or something, but when you went there you accessed their servers etc. and you got an ideal speed based on connecting to them, not just any other resource on the web.
 
Now after a few years ago with all this talk of throttling, I wonder if "they" would actually like Usenet killed. Many of these groups are unmoderated and cannot be moderated. they do not like that and we know it. I am not much into conspiracy theories but when you got people from government, industry and media going behind cosed doors to talk about shit they do not want us to hear, and their goal is clearly to enrich and empower themselvees at the expense of everyone else, what the hell are we supposed to think ?
 
But I am not going into that shit because of what might just be a few errors or poor maintaining or whatever.
 
I still would like to know why IE can access this but FF cannot.

Some banks have become a bit obsessive about cards since online frauds
became common. My bank sent me a kit of new cards to use and a number
to call with a authorisation code for the cards. When I called I gave
a woman details about my previous location just to see what happens.
Apart from a monthly statement sent my current location showing my
overdraft limit I get nothing from the bank. The bank says they never
ask clients to call them. It's about a month now and there are no
transactions on the cards. I only use cash and online transactions. I
don't use cards at all.

Simple question:
 
Q: Which app do you use on iOS or Android to figure out all the cellular
towers and signal strengths of the cellular signal (CDMA or GSM) in your
area?
 
Q: Does that app show you *all* the towers that your phone can see
(or does it only show the one tower that your phone is connected to)?
 
On Android, I am currently testing these GSM/CDMA signal strength apps,
where you can see my actual screenshot results in the photos below.
 
01 Network Cell Info Lite, version 3.30:
http://i.cubeupload.com/HoKTav.jpg
http://wilysis.com/networkcellinfo

02 Network Signal Info, version 3.63.01:

03 GSM Signal Monitoring, version 4.02:

https://play.google.com/store/apps/details?id=com.signalmonitoring.gsmsignalmonitoring
 
04 Netmonitor, version 1.2.15:

05 CellID Info:, version 1.2.2:
http://i.cubeupload.com/X3gsfb.jpg
https://play.google.com/store/apps/details?id=net.its_here.cellidinfo
 
06 RF Toolbox (Cell Monitor), version 2.26:
http://i.cubeupload.com/y2YfEV.jpg
https://play.google.com/store/apps/details?id=com.btapps.rftoolbox
 
07 WiGle WiFi Wardriving (which also reports cellular towers):
http://i.cubeupload.com/ZPva3O.jpg
https://play.google.com/store/apps/details?id=net.wigle.wigleandroid
 
08. OpenSignal, version 5.10:
http://i.cubeupload.com/BwfSFa.jpg
https://opensignal.com/app/
https://play.google.com/store/apps/details?id=com.staircase3.opensignal
etc.
 
On iOs, I looked for similar apps, and found this:
 
01 OpenSignal, version 4.0.5 (but it doesn't seem to report the nearby
tower and signal strength):
http://i.cubeupload.com/rmPsVg.jpg
https://itunes.apple.com/app/opensignal/id598298030
 
The one bad thing is that all these apps only show one cellular tower, even
though I know I have *two* microtowers inside my house, so, I think I need
to find a better app which will show *all* the cellular towers it sees.
 
To that end, I ask this scientific debugging question:
 
Q: Which app do you use on iOS or Android to figure out all the cellular
towers and signal strengths of the cellular signal (CDMA or GSM) in your
area?
 
Q: Does that app show you *all* the towers that your phone can see
(or does it only show the one tower that your phone is connected to)?

I use OpenSignal on my Android, in the UK. It currently shows '100
nearby' cell towers on the first page (where your screenshot shows '0
nearby') and they are shown as points on the map within a mile or two of
where I am (in a large busy city). But I'm pretty sure that comes from
the OpenSignal server not from the phone's own hardware. Likewise the
information it claims to have about nearby WiFi hot spots. The phone
and Google work out where you are and OpenSignal send you the data they
have for that area.
 
So if OpenSignal have few users in your area they'll have little or
nothing to tell you about.
 
Your phone will be able to tell OpenSignal about the cell tower it is
currently connected to, and OpenSignal can add that to their database.
If the operator of that cell tower has made its location public,
OpenSignal will even be able to place it accurately on the map -
otherwise they'll have to estimate its position from the signal
information their users provide.
 
I don't know the other apps you mention.

If electronic devices couldn't be repaired, then they had to be
recycled, so as not to poison your air, soil, seas, rivers and

I think you need to acquaint yourself with the term "elsewhere pollution". When the US EPA started regulating dumping, air quality and water quality, and when individual states began to realize that they also had to control such activities within their borders, Industry reared up on its hind legs like a threatened virgin, and whined about the costs involved and how many jobs would be lost as a result.
 
And, it is true that some of the most polluting industries did reduce in scope and volume, with primary reference to primary commodity or commodity-based uses - coal, steel, mining in general and similar. But as a brief visit to West Virginia will show, the worst of it continues to this day without let-up - although low natural gas prices are reducing the volume.
 
BUT - and as it really happens: Most of the jobs actually lost are due to automation, increased efficiency and better technique. One example: Lukens Steel - now AcelorMittal - operates the longest continuously operating steel mill in the US (206 years of continuous operation). It has produced roughly the same amount of plate annually for about the last 40+ years, but gone from approximately 3,000 workers to less than 800 in that time. Automation and efficiency. It has gone from burning coal to one (1) electric arc furnace. Cleaner.
 
And that is only one (1) example.
 
One more tiny example: Glassphalt - a glass based asphalt that can use glass that would be otherwise difficult to recycle in sufficient volumes to be efficient. It is still in use, depending on local economics, stone costs and applications. Point being, that if the US had to handle its electronic waste in a non-polluting way, it would figure it out - and some prices would rise as a result. However, it need not do so as the economics around that waste create sufficient demand *elsewhere* to cover the costs of getting it there.
 
We are sending our pollution to the Far East, Africa and other locations both in primary production and waste. But it is not as if those destinations are not asking for it, they are actually demanding it. A country that burns lignite as a primary power source, and dumps chemical wastes in its rivers without any sort of regulation, and dislocates tens of thousands of its people for petty, short-term eyewash purposes will not be concerned with a little more cyanide or a little more tricholoethane in its soil or water, for now anyway.
 
And that is the way of the world. Nobody does anything *TO* a country economically, short of a shooting war, that the country does not invite or demand. And China is certainly no exception to this. Start at home and ask what home-grown forces are doing before whining about what the rest of the world is doing 'to you'.

NMEA 0183 is a combined electrical and data specification for communication
between marine electronics such as echo sounder, sonars, anemometer,
gyrocompass, autopilot, GPS receivers and many other types of instruments.
It has been defined by, and is controlled by, the National Marine
Electronics Association.
 
Can I somehow plug that NMEA-compliant cable into my phone?
Or into my laptop?
Or a desktop?

Yes, it is. And if you look someplace like here:

you can find a list of the "sentences" taht a GPS unit outputs/

You may have to go right to the GPS subunit to get the data, but you can
use any of several makes of serial-USB adapters, and any sort of TTY
emulator your OS supports. FWIW, I have found ones using CP-2102 and
Ft232 chips to be reliable, and ones with the PL2303 to be not so good.
 
Take care to get the polarity and voltages correct; most of the adapters
(but not all) use "TTL-level RS-232", where the logic one and zero
levels are inverted from "normal" RS-232. I have no idea what sort of
signal levels that particular device emits.
 
The GPS unit will output ASCII "sentences" which are plain text.

I bought three, one pound spools of Kester .031" 63/37 at a local
flea market last fall. I paid $10 for all three of them.
 
I also won a pair of half pound spools of Ersin Multicore on Ebay
for $15. They are .015", 63/37. Just keep your eyes open.

That is about the way of it. I have one 63/37 at the bench, one in the travel kit and one spare.
 
After all this time, I will not use anything but true eutectic solder. I even keep a small amount of CU/AG/SN eutectic lead-free solder for very special applications such as repairing jewelry. Not cheap, but does the trick.

Cable TV uses QAM encoding, and it has to be converted to feed the

Here is how I just now figured out how to construct a non-redundant Google
Groups URL to a Usenet post from years ago. If you have a better method,
please share, as I post this merely to share to help others use Usenet as a
reference.
 
I just did this today for the alt-home-repair newsgroup, so all I'm doing
is documenting the steps for others to be able to leverage in the future.
 
1. I needed to look up an old URL on how to wind garage door torsion
springs so that I could cut and paste a short Google URL as a reference.
 
2. I knew the original thread was posted to alt.home.repair by me on Usenet
years ago, so I searched using this easily remembered URL.
http://tinyurl.com/alt-home-repair
 
3. That easily remembered URL, of course, takes you to the canonical GG
search URL which is the one to use (but it's harder to remember):
https://groups.google.com/forum/#!forum/alt.home.repair
 
4. My search was "Danny garage torsion" which came up with four thread
titles:
a. Lessons learned installing a torsion spring in a typical
residential garage
b. Update to the "lessons learned" garage door torsion spring DIY thread
(new lessons learned)
c. Garage door torsion spring relocation project (Status = Not going well)
d. Garage door torsion spring broken ... and ... I have no questions! :)
 
5. The initial URLs are messy because they include redundant terms:
a.
https://groups.google.com/forum/#!msg/alt.home.repair/738YR8CPsLI/BRHYK3X71BAJ;context-place=forum/alt.home.repair
b.
https://groups.google.com/forum/#!msg/alt.home.repair/AGrGZc4i-RA/8Ff3HsrmASEJ;context-place=forum/alt.home.repair
c.
https://groups.google.com/forum/#!msg/alt.home.repair/ifuMBLOoGXY/Hk0mfwDsQooJ;context-place=forum/alt.home.repair
d.
https://groups.google.com/forum/#!msg/alt.home.repair/s0zBJNaT89Q/I0TP541gGk4J;context-place=forum/alt.home.repair
 
6. Notice the unique ultimate characters:
a. LASTID=BRHYK3X71BAJ
b. LASTID=8Ff3HsrmASEJ
c. LASTID=Hk0mfwDsQooJ
d. LASTID=I0TP541gGk4J
 
7. Now you need a normal short URL, where a "normal" URL can be gotten
simply by looking up the *latest* page and choosing any URL found on that
latest page as of the current date.
https://groups.google.com/forum/#!forum/alt.home.repair
 
The first URL (at the moment) uses this non-redundant syntax:
https://groups.google.com/forum/#!topic/alt.home.repair/i9nfxKFjZE0
 
8. You'd think you can just cut the *last* argument out, to reconstruct the
desired non-redundant Google URLs (but you can't). So these won't work:
 
https://groups.google.com/forum/#!topic/alt.home.repair/<cut this out>
https://groups.google.com/forum/#!topic/alt.home.repair/<insert LASTID>
 
a. https://groups.google.com/forum/#!topic/alt.home.repair/BRHYK3X71BAJ
b. https://groups.google.com/forum/#!topic/alt.home.repair/8Ff3HsrmASEJ
c. https://groups.google.com/forum/#!topic/alt.home.repair/Hk0mfwDsQooJ
d. https://groups.google.com/forum/#!topic/alt.home.repair/I0TP541gGk4J
 
But that doesn't work.
 
9. What you can do though, is cut TWO ID sections out:
a. LAST2IDs=738YR8CPsLI/BRHYK3X71BAJ
b. LAST2IDs=AGrGZc4i-RA/8Ff3HsrmASEJ
c. LAST2IDs=ifuMBLOoGXY/Hk0mfwDsQooJ
d. LAST2IDs=s0zBJNaT89Q/I0TP541gGk4J
 
10. Using those two sections, you reconstruct a Google URL:
 
https://groups.google.com/forum/#!topic/alt.home.repair/ + <LAST2IDs>
a.
https://groups.google.com/forum/#!topic/alt.home.repair/738YR8CPsLI/BRHYK3X71BAJ
b.
https://groups.google.com/forum/#!topic/alt.home.repair/AGrGZc4i-RA/8Ff3HsrmASEJ
c.
https://groups.google.com/forum/#!topic/alt.home.repair/ifuMBLOoGXY/Hk0mfwDsQooJ
d.
https://groups.google.com/forum/#!topic/alt.home.repair/s0zBJNaT89Q/I0TP541gGk4J
 
11. When you go to those four URLs, you get *new* Google URLs for each:
a. https://groups.google.com/forum/#!topic/alt.home.repair/738YR8CPsLI
b. https://groups.google.com/forum/#!topic/alt.home.repair/AGrGZc4i-RA
c. https://groups.google.com/forum/#!topic/alt.home.repair/ifuMBLOoGXY
d. https://groups.google.com/forum/#!topic/alt.home.repair/s0zBJNaT89Q
 
12. So, one way to reconstruct a non-redundant Google Groups URL is to put
these three syntactical items together:
A. The base URL (https://groups.google.com/forum/#!topic/)
B. The newsgroup (alt.home.repair)
C. The penultimate ID
 
https://groups.google.com/forum/#!topic/ + alt.home.repair/ + PENULTIMATEID
