I'm so conservative, I would even include veterans benefits

I have a veteran friend that tells
me he has received over $1 million dollars in veteran retirement
benefits. He also says that doesn't include healthcare payments,
which because of the zipper up his chest, have been considerable.
I'm for an across the board cut in all government expenditures.
2% every year for 5 years would be a good start.
If under Obama, the real median household income dropped $2,627—or
4.89 percent—from 2008 to 2012*. Why should government wages go up.
Oh! sorry, but you started it.

My VA Disability is $1046 a month, and that isn't retirement pay. I
am allowed no other income, at all. Even one dollar income would cost
me my medical care and that tiny pension. I don't know any Veteran who
got a million dollars, unless they won a lawsuit. It's damned near
impossible to win a lawsuit against the VA. Tell me how long you could
survive on $1046 a month? My 1979 pickup truck is falling apart. It
needs more in repairs than it cost, eight years ago. I have three
leaking roofs, and a bad tank on my well. The pump kicks on three times
to get one quart of water. Do you know what that will do to the pump? My
pension went up about 1% per year, and only some years. You're ignoring
the guarantee they give people entering the service of medical care and
disability benefits, in exchange for lower monthly pay while on active
duty, or in the reserves. Whine all you want, I'll consider the source.
$2,627 would be a 21% reduction for me.

Is Gmail OK... no labeling mail with "spam" like Cox does to every
other LTspice digest? No ads inserted?

Of course gmail can change their service at any time they wish, but the
emails I receive are not altered in any way other than the usual headers
added by servers which handle the messages (which can be useful when
attempting to track the source of emails). My outgoing email does not
go through gmail. It goes out through the hosting server.

How do you set up gmail for POP retrieval? Server name, settings,
etc?

...Jim Thompson

There are instructions on the site. Basically it's pop.googlemail.com,
port 995 on RX, and smtp.googlemail.com port 465 on TX.

could do that by setting up an account for each

single account to make reading it easier. I haven't done that because
there are just too many merchants with which I do business to make the
effort worthwhile. Looking at my password list (spreadsheet), I see
about 100 merchant accounts, which use my email address as a login
name, which means I have to keep those email account active
essentially forever. No thanks. Knowing which merchants are really
evil or insecure isn't worth the effort.

Neither do I. My suggestion to run a personal mail server was in
reply to Jim Thomson's problem of dealing with 100+ email addresses.
Having total control over the situation will work, but as you note,
the overhead is rather high. I never expected Jim to follow my
suggestion, but I did want to inform him what's involved in
implementing the solution.

Hosting your own email is a time sink if you're going to
do it well, whereas it's easy to get reliable service with hosting
outfits.

Most (not all) email hosting and filtering services charge by the
account.

Having two mail accounts, with the main one forwarding copies
of everything to the backup one, protects you from most sorts of cloud
glitches, apart from the NSA. You can migrate all your own emails from
one to another using specialized migration outfits (it costs about $5).
(Change the passwords after migration.)

I was doing something like that until recently. I got tired of
dealing with the spam, so I forwarded all my email to my Gmail
account, which then forwarded it to a 2nd email account. Nothing
would ever appear in my first account or on Gmail, but the 2nd account
was spam free. However, the risk of false positives became to high,
so I dismantled the mess. I currently use SpamCop:
<http://www.spamcop.net>
at $30/year per email address.

The other thing is to use a POP3 client such as kmail (my fave) or
Thunderbird. That way you have N local copies of all your email on
different boxes, which makes you pretty well crash-proof locally as well.

I've used both POP3 and IMAP4 over the years for email. Each has
their advantages. For archival storage, POP3 is quite good. Have one
machine download everything, and leave about 2-4 weeks of email on the
server. That was fine when I read email on one or two machines. I
now have 3 PC's, 2 Mac's, 1 tablet, 1 smartphone, and a Chromebook (on
order), all of which are used to read and send email. Reading the
same email, and deleting the same spam eight times is a bit too much
duplication of effort. Actually, that became a problem when I added
my 3rd machine.

So, I switched from POP3 to IMAP4. I can login to any machine and see
my email exactly as it looks on any of the other machines. For
archival purposes, I have one machine collect about 1,000 messages,
which is saved to a local folder using Thunderbird. At that point,
those messages are no longer visible on the other machines. The only
downside is that moving from the active IMAP4 folders (inbox, sent,
trash, junk) to a local folder requires that the client re-download
all 1,000 messages from the server, even though all those messages are
present on the local machine. Dumb design, but unlikely to change.

However, IMAP4 does have a big weakness, which you hinted. If I
accidentally erase a message from one machine, it disappears from the
server mail store, and from all the other machines. When that
happens, I just fire up one of the other machines without being
connected to the internet, so that it will NOT sync the folders, and
extract the missing message. So far, I've only had to do that about
twice in the last 3 years.

Drivel: Sorry about mis-guessing the number of working days per year.
Instead of doing the arithmetic, I fished the wrong number out of my
rapidly fading memory.

I don't know, that's not what I did. I set gmail to forward the mail
back to my domain. The main reason I did this was to make it easy to
cut gmail out of the path if any problems develop. Just change the
forward to gmail to the same email address gmail was forwarding to and
you are done. Nothing else has to change anywhere.

I recommend that you do it this way, but I think you can set gmail as
your POP server. A friend who uses an iPhone does that I seem to
recall. The client on his phone checks email from several sources
including gmail and hotmail. He is very non technical so I'm sure it
isn't hard. I believe there are instructions in the gmail setup page.

Bingo! That is *exactly* what I do. No real work. Each time I give
out an email address to a vendor (meaning virtually any web page I'm not
giving a spam catcher yahoo address) I take the 15 seconds to add an
alias to the website emailbox. The address is usually
domain.com@mydomain.com so it's not like it is hard to remember. I also
get some interesting responses when they are viewed by a human.
Sometimes they contact me by phone because they think it must be a
mixup, lol. Ok, I guess if you are busy this is a bother, but it is way
below my threshold of pain.

Hosting your own email is a time sink if you're going to
do it well, whereas it's easy to get reliable service with hosting
outfits.

Most (not all) email hosting and filtering services charge by the
account.

My account is about $60 a year and is for hosting multiple web sites
with no stated limitations. At one time I had a site with multiple TB
of data flow per month and no complaints. Certainly email addresses
aren't charged separately. Heck, they don't even know how many I have.

Having two mail accounts, with the main one forwarding copies
of everything to the backup one, protects you from most sorts of cloud
glitches, apart from the NSA. You can migrate all your own emails from
one to another using specialized migration outfits (it costs about $5).
(Change the passwords after migration.)

That is an excellent idea. I can set up a mailbox to forward the emails
to two other accounts, one pulled off regularly by my main computer and
the other pulled off intermittently by a backup computer. The only
glitch is the lack of backup of the outgoing emails without manually
CCing the backup account.

I was doing something like that until recently. I got tired of
dealing with the spam, so I forwarded all my email to my Gmail
account, which then forwarded it to a 2nd email account. Nothing
would ever appear in my first account or on Gmail, but the 2nd account

Right now I am using Eudora and backup the email folders to an external
hard drive. I lost a computer... my only real computer back in
November. It took me a while to get it all set up and working but I
didn't lose a thing. Of course the ultimate backup was the laptop
hard drive itself. I pulled it out and put it in an external USB case.
There were a couple of files that were corrupted, but nothing
significant. All the important stuff was on the 3 TB external drive.

Totally manual. When I open a MUA (mail user agent), the first thing
I do is manually check off everything that looks like spam and hit
delete. In Thunderbird, that moves them into the Trash folder. Before
I exit the program, I take a look in the Trash to make sure there's
nothing in there that doesn't belong. That works fine during normal
working hours. It's not so reliable when I'm half asleep, overworked,
stressed, or in a rush. Much as I would like to automate the process,
the risk automagically deleting something important is too high.

Incidentally, some of my clueless friends and customers don't really
know how to write email. Looking for an example to emulate, they
often copy the style and formatting of the spam their receiving.
Fairly soon, I'm getting email from them that looks very much like
spam.

> But that could delete a brand new message from the server.

Yep. That's the problem. Hit delete and it's gone everywhere.

I get too many emails a day to deal with the manual deletion from the
server for that to work unless I am missing something.

I once timed myself and found that I was spending about 1 to 2 minutes
per session dealing with manually deleting the spam. My ISP does a
good job with the obvious spam, but isn't perfect. I do the rest. I
read email about 6 times per day. That's 12 minutes maximum, which I
think is tolerable.

The other limitation to IMAP is the lack of syncing the outbound emails.
Or is that something that IMAP4 does which I am not aware of?

Huh? My Sent folder is synced on all my IMAP4 accounts. That's
standard. More complicated is syncing Trash and Drafts. That's
usually an optional setting. Syncing drafts is fairly important for
me as I'll start an email in the office, and then finish it on my home
computer.

Right now I am using Eudora and backup the email folders to an external
hard drive.

If it's the OSE version of Eudora, it's basically an old version of
Thunderbird in disguise.
<https://wiki.mozilla.org/Eudora_OSE>
I suggest you use the native Thunderbird application, which is quite
similar to the original Eudora.

Image 2013 ($50). Between image backups, copy off files that have
changed with whatever backup program handles incremental backups by
date. Part of my collection:
<http://802.11junk.com/jeffl/crud/backup-drvies.jpg>
There are about 8 more scattered around. Most are 1TB.

So, what are you going to do if your 3TB external drive gets trashed?
I had it happen when I was playing with a "cleanup" utility, that
decided to "cleanup" the external USB drive by deleting important
files. I had to use an unerase utility to recover. Grrrr...

Yep. That's the problem. Hit delete and it's gone everywhere.

I think we are on different wavelengths here. Are you saying that all
of your email remains on the server forever using IMAP? My intent was
to use one computer to download the mail via POP and delete it while the
others all just downloaded using POP it without deleting. The trick is
to synchronize them so the deleting computer always ran last. I was
never confident about this so I've never done it and just do email on
one computer. As I also mentioned, this doesn't do anything for sent
emails nor does using IMAP.

I get too many emails a day to deal with the manual deletion from the
server for that to work unless I am missing something.

I once timed myself and found that I was spending about 1 to 2 minutes
per session dealing with manually deleting the spam. My ISP does a
good job with the obvious spam, but isn't perfect. I do the rest. I
read email about 6 times per day. That's 12 minutes maximum, which I
think is tolerable.

I'm not talking about the spam. The other problem with keeping all the
emails on the server is the inability to see them unless you are online.
I use a laptop and there are times I can't get a connection, like at a
customer's site where they aren't keen to grant Internet access, mostly
due to issues of getting to the right person to turn it on. I can at
least read emails if they are on my computer.

The other limitation to IMAP is the lack of syncing the outbound emails.
Or is that something that IMAP4 does which I am not aware of?

Huh? My Sent folder is synced on all my IMAP4 accounts. That's
standard.

I don't follow. I've never found a way to put email in a "folder" using
IMAP. I guess there is something I need to learn.

More complicated is syncing Trash and Drafts. That's
usually an optional setting. Syncing drafts is fairly important for
me as I'll start an email in the office, and then finish it on my home
computer.

So these folders are on the email server? Sounds a bit like cloud storage.

Uh, you have it backwards. OSE *is* Thunderbird, just with some sort of
a GUI app to make it look like Eudora. I think I tried it once and
hated it so I never "upgraded". I am using the original Eudora which is
*nothing* like Thunderbird (the program I am typing this on) and love
it. They will have to pry it from my cold dead hands.

I don't play with utilities. But if the 3 TB drive is lost, I get a new
one and start over. I won't have lost anything unless my laptop goes
south at the same time.

I do have some 40 GB of map data I've never moved over to my laptop. I
need to copy that over too some day. But then that is also still on the
HD from the old laptop in an unknown condition of course. I can
read/write the old drive, but it has its own issues and was going bad
before the laptop died.

I still haven't gotten used to Win8. Who is the idiot who thought it
was a good idea to get rid of the start menu? How about providing a
"classic" interface option for those of us who aren't using a tablet or

Exactly where is a good description for all these options?

...Let alone how to use them?

Stuff like GEAR is well documented by most SPICE descriptions, and
computational solvers in general; it's their word for Runge-Kutta of order
MAXORD. Note that TRAP (trapezoidal, i.e. Newton's Method, more or less)
is essentially RK1.

For even more information, consult books on numerical methods,
especially numerical solution of differential equations.

Also books on linear algebra, especially numerical methods.

I very rarely use TRAP in my simulations because the settling is poor and
erratic (the result is a distinctive alternation, every other timestep, of
a given variable about its ideal value -- it looks like triangles when
zoomed), particularly for nonlinear (switching) circuits. Occasionally, I
find RK4 (GEAR, MAXORD = 4) beneficial: the average timestep is calculated
much more slowly (more derivatives to compute), but the worst-cases are
much better -- it's not digging as deep (constantly redoing a bad
calculation at progressively smaller timesteps) or as often, around
strongly nonlinear events (such as switching edges), so the overall
simulation can run faster (and more stable -- less likely to get stuck on
a randomly too-small timestep).

I don't believe I've ever seen GEAR2 produce "bobbling" results; either it
settles asyptotically, or the oscillation is really there (as evidenced by
finding a smooth sinusoidal oscillation after setting smaller RELTOL
and/or max. timestep to enhance detail).

As for "how to use", judging by the dearth of instructions or even useful
documentation on most SPICE settings, I can only assume three things:

1. Don't touch that, you'll screw it up! Use the default settings! If it
starts throwing errors, the circuit /must/ be impossible!
2. Play with all of them and see what works. Life is a journey, or
something.
3. I know what works, but I'm not going to tell you.

Against the apparent collective wisdom of all three, I dare suggest these,
which seem to work well enough (these are in Multisim, which is your basic
XSPICE backend):
http://seventransistorlabs.com/Images/SimSettings1.png
http://seventransistorlabs.com/Images/SimSettings2.png
http://seventransistorlabs.com/Images/SimSettings3.png
but not all are available in LTSpice, so YMMV.

The most obscure setting of them all seems to be pivot (PIVREL, PIVTOL).
It's purely a computational thing, and of the few references I can find to
it, the only sentiment is "does nothing, leave it alone". Yet I've had
more than a few failing circuits fixed by setting a more strict (larger)
value, like as shown. I dare someone to explain that.

They are most likely talking about pivoting, which is done in the
solution of linear equations by gaussian elimination. Spice solves a
linear equation at each time step.

If these are really absolute and relative tolerances (as the names
would suggest), I doubt that larger values are more strict. Making
these tolerances larger makes the algorithm less fussy.

Anyway, it's a long story, but the system matrixes that describe
circuitry are quite nonlinear (all those semiconductors!) and are often
ill-conditioned (and thus very sensitive to tiny errors). A lot of
this is in Nagel's PhD thesis, the founding document of SPICE, although
SPICE has evolved considerably since then.

Oops, I probably had "less strict" or "more relaxed" in my mind when
typing that. Or, you know how it is when talking about loading with
resistance (a reciprocal quantity).

..<http://en.wikipedia.org/wiki/SPICE

If it has evolved significantly, then why haven't partial-matrix
tiumestepping methods and such trickled down to our level yet?

My understanding of the average commercial offering is, they either start
with 3f5, which was the last and most useful Berkeley version, or XSpice,
which includes digital models and a couple more convergence hacks (I think
it introduced Gmin stepping..?). And apply their own proprietary mods
from there (PSpice with more functions and weird syntax; HSpice with even
more, and some more convergence I think, and those fucking encrypted
models; LTSpice with multithreading, also encrypted models; etc.), with a
graphical schematic capture and graphing and postprocessor tossed in
front. And ALL the low to mid level software (OrCAD, Altium, etc.)
resides at this level and there is simply no core development or
competition beyond that level. Which it seems to me, if it weren't for
the grace of academia having written SPICE for free, these companies
wouldn't give less than two shits abuut putting simulation in their
products at all!

Love those ST Cortex M? processors. The pin selection utility in Cube is
awesome but it would be nice if they added the source and sink
capability of each part to it. The Nucleo boards are so cheap that they
can be used in a variety of projects.

It's even worse than that. Some of them have programmable drive strengths,
so it depends on the software you are using as well as which pin you are
using.

When you say a 100 uA pullup, is this *really* a current source or a FET

just make the input high impedance or use a lower current pullup?

This is an already existing chip... designed (by me) for another

purpose in spite of it is not really a match :-(

I don't get the problem. Give him a spec on your input and either let
them deal with the interface, or you can design an interface circuit
once you see the data sheet on the DAC output.

Where is the problem?

BTW, is your input digital? If not, why do you have a "current source"
on it? No, forget I asked that one. I don't really want to know.

It's an analog input with a precise 100uA current source pull-up to
allow the user to simply add a resistor to ground to set a threshold
value for an internal comparator. Now they want to force it with an
external voltage source. I'm gathering that uP DAC outputs are
weenie??

Ok, now we know the rest of the story. I can't say how "weenie" the DAC
on an unspecified chip might be. I have no idea how you can draw any
conclusions. Why can't you just let the customer drive the signal
knowing the requirements?

There are such specs on every processor and FPGA I've seen.

And they are all different. Even one single processor often has separate

Sure, this whole discussion depends on what is meant by "general
specifications". Yes, each device has its "general specifications".
Of course they're going to vary across manufacturers but I assumed JT
would know that not every pin in existence would be identical. Perhaps
I thought too much of his abilities. ;-)

Now, now! I don't use uP's, so I have to rely on what my customers
tell me they're going to do to my chips. When they tell me
nonsensical things I try to sort them out here.

Does every single chip you've ever designed have exactly the same I/O
parameters? Why should uC I/Os be any different? Get the spec and
read it.

Every end user will have a different uP.

Without some constraints, no answer to your question is possible.

I have since squeezed from _my_ customer that it will actually be a
rail-to-rail PWM... NOT analog as he first said, so the problem is
moot.

Do you know what its drive capability is? You better find out, or at
least specify the limits.

ok sir u guys had wrote the coding using BF981 but i dont know were we can use this netlist coding if the solution their means is their library files are present in that same tool for example if this coding is used in HSpice or PSpice is their library file available and i have another doubt is why the transistor model is not available in LT spice or any Spice list.

If you don't mind me asking, where is your post? I am much interested in that spice model. Thanks!

 

I have the same problem, when I try to sim welding smps.

dit all things but it do not work, except when remove the opamps from the feedback, sometimes it do start, but most not.

I have file but do not now where to post.

Hello,

I've built a small CNC machine that should, in theory, be able to mill a
blank copper clad card to create a two sided PCB. I'm moving into the
testing stage and would like to get more serious about the software.

Has anybody done this before (hobby niveau)? If so, what kind of
workflow did you use?

In particular:
- Is there a particular PCB CAD application that outputs the appropriate
type of file ("negative" HPGL for example)?
- I gather "positive" HPGL files must be cleaned up to account for the
cutting tool size and cleaning out large areas of copper. Are there any
good applications or shareware out there? Projects?
- Any hardware issues (does a special 60,000 RPM motor really help???)

Any pointers would be appreciated.
