> I did have it set up with Thunderbird and AIOE (IIRC) and it did not solve my problem. It still had access issues. Then all that cleared up, but then so did Google, so I just went back to that. It bitches about my browsers but when it says "A problem occurred while communicating with the server" it is NOT a browser issue, especially when the same browser works a half an hour later. So I am not "upgrading" anything. But then if I have to go Thunderbird again I will probably get the new version of that. And it STILL might not fix my problem. Like updating drivers, it does not work, like I have no sound so I need the newer drivers, hows come it worked last week ? Bunch of bullshit.

Do they sell pre-paid visa debit cards where you are? Here one can hand
over cash and buy one. I prefer those when dealing with small online
transactions where I think the card details are likely to get stolen.
The most I can lose is whatever cash I handed over to buy (or top up)
the card, and to me this is better than the hassle and the cost of my
time and perhaps credit rating etc. to deal with trying to do a
chargeback through a bank. I can't recall whether I had to show ID when
I bought the card - but for my purposes it makes no difference as I am
not trying to achieve anonymity.
 
Regardless of the client software you use, you will need a news
provider, and I don't know whether there are any free good ones. ISPs
used to provide this included with the internet service but it is
getting rare these days. I pre-paid for a block of data (with
usenet-news.net iirc) a long time ago. As I don't use binary newsgroups,
it will probably last as long as I need without ever paying them again.

Four of five timers were trending the same way suggesting power line
frequency.
 
From 2/20 to 2/21 to 2/22:
 
Timer B1 got 47 seconds later then 38 seconds earlier.
 
Timer B2 got 55 seconds later then 58 seconds earlier.
 
Timer C1 got 41 seconds later then 32 seconds earlier.
 
Timer C2 got 82 seconds later then 39 seconds earlier.
 
Timer D1 got 10 seconds earlier then 14 seconds later.
 
The B's are nearly identical to the one whose motor I showed. The C's I've
never had open. The D's I've looked at but have no clue if it's a sync
motor or not. If not, it's kind of funny as that one seems to hew most
closely to the expected turn-on time.
 
Getting a vintage electric wall clock off eBay. Will set it accurately to
an NTP server and then watch it for subsequent variations. Inexpensive way
to look at this and then ultimately a useful device.

Years ago I designed and built a nixie clock with digital TTL counters using mains frequency as timing source. Here in Spain the typical variation I see is between 1 and 10 seconds per day and within some days I've seen it go as far as 30-40 seconds, then slowly correct back. That has been always the behaviour of that clock from 2007 to now. At long term time keeping is good.
 
I've found this website clock https://time.is/ a good time reference, I successfully calibrated a quartz clock with adjustable trimmer in a few days checking once per day and it kept perfectly aligned for a month. My previous attempts with some cheap DCF77 radio controlled clocks failed, apparently they randomly added or removed a few seconds on each sync.

I just had an idea. I have a UPS sitting around out of service as the
batteries went dead and even with good batteries I don't know how long it
would run even at very low load. I don't know how precise it is though
when I looked at it on a scope it was a nice sine wave and looked stable in
frequency compared to the mains. I could rig a 24VDC supply and use the
output of the UPS to run my group of timers that I am testing. If the UPS
has an accurate output then the timers should be accurate as well. If the
UPS is fast or slow then at least the timers will get ahead or behind the
same amount each day, not varying like I have observed. Hopefully it would
be stable at whatever frequency it is and not go up and down.

Join the club. :( :) I've had 4 or 5 (yeah I'm a sucker for Sunbeam
blankets) but don't want to be too critical of Sunbeam - they
have replaced several under warranty and replaced one totally.
 
Thee typical symptoms are that they do tend to get weaker over time, but
some die totally. The weakening may be related to the PTC (Positive
Temperature Coefificnt) of resistance of the wire used as the heating
element. It's self limiting so claimed to be safer since even
scrunching up the blanket should not result in an excessive temperature
rise. However, the change in resistance may not be totally reversible.
I doubt using preheat makes a big difference.
Since the power to the heater is pulse width modulated (around an 80
second cycle - yes, that long!), running at lower heat doesn't
necessarily help either.
 
When they totally die, I assume it's a bad connection issue, possibly
at the "module" - the wart attached to the connector, which has a
couple of discrete components inside and nothing else.
 
And I do now record the current used when new. ;-)
 
Google "Sunbeam blanket problems" or something like. There's a lot
out there.

I haven't done any real testing Sam, but just spitballing I'd guess that the more the Sunbeam is used, the faster it becomes inert. So, if run at lower temp settings, less heat/time will be supplied by the blanket and the longer it will last (?). I suspect it's decline is not linear, so keeping the temp down by half may quadruple the life..
 
At least that's my theory and we'll see how this new Sunbeam mattress pad holds up. We had two blankets before this heated pad (both Sunbeam) and both went *very* weak before being replaced. Neither showed any error code at the controller nor went completely cold, so neither suffered a broken wire anywhere. But even at level ten they barely got warm.
 
This new Sunbeam heated mattress pad we picked up last fall will be used no more than a max of 4 out of 10 (no preheat which does a level 10 for 30 min).

I don't remember seeing a question here about ATX PSUs and motherboards.
So if there is a better forum to ask my question no doubt someone will
tell me where...
 
My previous computer became progressively more reluctant to boot up and
eventually I gave up and bought a new ATX PSU in case that was the
problem. That was not a cure so I removed the motherboard as well and
bought a new one. That combination has been working ever since, with
enough problems to be interesting, of course...
 
But I would like to know if anything can be done with the old PSU and
motherboard combination. If I power up the PSU alone by shorting the
green PS_ON connection to ground the fan turns and voltages appear
briefly, but then it goes dead again.
If I connect the PSU to motherboard and short the front panel "on"
contact the same thing happens. The CPU fan turns as well as the PSU
one, but only momentarily.
 
I took the cover off the PSU but the inside shows nothing untoward.
 
Is there anything that I can do for some more diagnosis? The
motherboards is a GA-8ISXT-FS and the PSU FSP300-60ATV with a 20-pin
main power connector.

AT one time many mother boards were failing because the capacitors on
them were defective. Look at some of the big ones tops, especially near
th eprocessor and those coils of wire. If they are sort of dome shaped
instead of flat, that would be the place to start.
 
Sometimes you could heat the board and it would start and then run for a
long time. Cut it off and you had to heat it again to get it to start.
 
I sent a couple of boards back for replacement due to this problem years
ago.

There's a lot that can be done as far as diagnosis, but learning to diagnose
computer problems is ... better left to folk who do it fulltime.
 
Power supply problems are testable without having a new power supply.
Motherboard problems are testable and detectable, but rarely fixable (the
bulging-capacitors issue of 2000-2010 vintage being a notable exception).
 
Your best plan, if you suspect a hardware problem, is to FIRST rule out
software (and firmware) issues. Then, visually inspect (for loose or dirty connectors,
burned-up components, stalled fans, etc.). Then run test software for common
issues (memory, hard disk). At this point, though, you're left with
having to repace major parts (like a motherboard or CPU), which you already know.

That's so BS, but it may be a cultural thing. A friend was in a taxi in
Vietnam and a cyclist was hit. The two drivers started haggling and
bystanders joined in to mediate. In the end it was decided that the
cyclist should get $50. They said my friend should pay.

Sounds like a good scam. Perhaps the same "bystanders" do that every
day...

Try Jameco. They have a $20 minimum and sell a lot of "pulls" & odd stuff.
Almost all are "through hole" devices, which can be handy.

No brain function before my morning tea. That's wrong. There is no
backlighting in an OLED display. That should be the LED "screen"
power consumption, not backlighting power consumption.

So you are pulling 450 ma, or thereabout per hour. If your AAA batteries
are
 
middle-of-the-road 1,000 MAH, you have a base of 3000 MAH, so, about 6-7
hours
 
+/- or so. Under normal use, that is 'days'.

The internal resistance of the batteries, and the internal resistance of
the LEDs used, is very much a part of the design of those flashlights.
Both the LEDs and the batteries do get warm in normal operation,
and (as you suspect) it's likely that a fresh set of batteries will last
well under a day of ON operation; Duracell AAA claims 3.5 hours at 1/4W
output, so a three-cell light could deliver over half a watt for a useful
amount of time; hours, not days.
