    Probably not. Usenet has a range of hosts. Google supported the usenet
    on its forums because it was a cheap service to offerand got a lot of
    clicks. Now that the spammers have started to exploit it, it's cheaper
    for them to walk away that it would to spend money on blocking the

    I am unclear: they don't say GG is ending, just that the link to usenet
    is severed. Does that mean there will be a fork into two SEDs - one on
    usenet and the other a GG?

    All they are saying is that they used to pick up posts from usenet, and
    that they are going to stop doing that from the 15th February 2024.

    The archive will still be there, but it isn't going to be kept up to
    date any more.

    Sci.electronics.design existed before google groups, and it will
    probably survive without them. Some regular posters despised people who
    took advantage of google groups and will probably be happy that posts
    will again be restricted to the glass teletype format and go away after
    a couple of days.

    I recently became thoroughly fed up, and started filtering all
    messages originating from googlegroups out of my small leafnode-
    type feed.

    The total traffic in most newgroups which still had any, dropped
    by about 90%.

    I don't doubt I'm missing a few interesting messages posted by a
    few interesting humans... but the massive reduction in spam seems
    a worthwhile price to pay.

    It will be interesting to see if the volume and quality of USENET
    traffic ever starts to recover from the damage done by Google's largely-unmanaged flooding from googlegroups.

    Well, John Larkin could start a conversation or whatever they call it on X?
    I left twitter years ago, but maybe I would follow it.
    If Usenet dies...

    Indeed many Usenet groups I used to read are dead or almost dead.
    Downloading the group list is long, but many are empty.
    Larkin is one of the few here that actually shows circuits.

    An other alternative is groups.io

    Probably -- I've been trying to dig up schematics / guides for making
    little altoid-tin CW tranceivers (kinda fell into ham raido thanks to

    effect of "Buy my premade module!", with maybe a VERY small handful of old-timers who still have schematics...

    Interesting to see that Google usenet servers weren't even
    in the top30 in the previous few years and are heavily
    influenced by northern hemisphere school attendance, by
    month.

    I wonder if this means that school system PCs are being
    inadvertenly used as spam generators/amplifiers?

    I expect there's little money or expertise to police that
    sort of thing and plenty of machines to play with.

    I just looked at google groups SED page for the first time in

    It appears to me that IF usenet posts were no longer present, then

    The same as SED is now. I often load XNEWS and find 50 - 100 posts available. After spam is removed, there may be zero to 1/2 dozen posts left to read - including yours.

    I don't see any of the tagalog posts on usenet and my plonk
    file would bust if it had to deal with all those showing on
    google groups.

    For spam, a time-limited block usually suffices. There have
    been times when a new kill filter wouldn't stick. I weeded
    out old entries and it seemed to do the trick, hence my
    guess at size limitations.

    None of the google groups spam authors or subjects are
    identified in the current list, but I don't see them posting
    on usenet, either.

    I'm using agent V4.2.
    Maybe it's broken here, but in a good way.

    I treat every poster who posts off-topic or useless posts, or posts to more than one newsgroup, or who wastes my time, as a spammer. I am interested in people who give useful information worth saving. I plonk everyone else.

    This leaves very few people out of the group. If I plonk someone who accidentally posts something useful, it will appear in comments by someone in the reserved group. Otherwise, it is not interesting enough to bother.

    I am still using the Usenet newsreader I wrote around year 2000 or so, basically when I started with Linux in 1998
    and there was no Agent for Linux, before that I used windows 3.1 running on MSdos.
    https://panteltje.online/panteltje/newsflex/index.html
    I see very little if any spam, filters are excellent.
    Ported it to Raspberry Pi 4, been posting from that now for a year or so. Filter for sci.electronics.design is just a few words...
    What's the problem?
    Sellers always use specific words.
    I am on Solani now, faster response than Once In September.

    Google is doing fine. Usenet is struggling.
    Google did offer google-groups users the opportunity to report spam. and
    in times past the limited amount of spam that showed up got deleted
    after it was reported. Google doesn't seem to have bothered to automate
    the process, and the south-east-asian online gambling industry flooded a previously adequate system.

    A possible replacement to a usenet group would be a mailing list.
    Most of us do have a domain and could host it. It won't be as free
    as usenet as the hosting person(s) will have control - and also
    plenty of work on their hands to fend off the spammers who are trying
    to kill this group (they tried CAE, too, saw no traffic there and
    let it go).

    Yea, I just have a pack of A4 paper, take one, draw a circuit on it,
    punch holes in those and put those in an map.
    I have close to a thousand circuits now,
    Some time ago I photographed all of those and put those on a 1 TB USB stick. The USB stick died after a few weeks, the maps and paper schematics still exist.
    I _did_ make a backup of that USB stick on magnetic harddisks though :-)

    Now I have the same problem with music, hard to read my own music..
    But it works!! :-)

    I'm going to take up donations to buy you a pencil sharpener.

    Cool!
    Anyways, long time ago when I uploaded pictures of my pencil drawn circuit diagrams
    the high resolution images were converted by the web hoster to low resolution ones.
    I complained, then they changed that.
    I now left US godaddy hosting altogether and use a Dutch hosting company.
    The final straw was that godaddy stopped with pop email.
    Everything OK so far.

    Beautiful schematics work better. There's a good reason for that.

    One thing that annoys me is that some people refuse to make a 4-way
    connection, and do ugly things to avoid it. They must use cheap
    Chinese connection dots that fall off the paper onto the floor.

    Another annoyance is a sch or sim that's 2-bag ugly and has no hint of
    author, date, or what the hell it is.

    Beautiful schematics work better. There's a good reason for that.

    Engineers who care enough about what they are doing to make the
    schematics they draw look good also take care that circuit works well.

    One thing that annoys me is that some people refuse to make a 4-way connection, and do ugly things to avoid it. They must use cheap
    Chinese connection dots that fall off the paper onto the floor.

    Another annoyance is a sch or sim that's 2-bag ugly and has no hint of author, date, or what the hell it is.

    You can always add text to a schematic or an LTSpice .asc file, and if
    you care about keeping the intended viewer well-informed you will do that.

    The stuff you post here, with generic op amps and transistors, suggests
    that you don't,

    When I first used a computer, I took the time to construct a lot of
    electronics symbols and put them in a library. They were designed on
    the grid system which my drawing programme used, so they aligned with
    each other and the lines joining them. I looked into the crossover
    problem and decided that a gap and staggered '+' junctions removed all possibility of misunderstandings, so that was the system I adopted.

    The result is that quite complex diagrams are easy to draw and
    understand:

    Yes - sometimes I find a prototype board in the junk pile and can't even remember making it or what it was supposed to be.

    and the transistor on pin 1 of the PIC:

    That is also a low level SWR bridge, added an OLED display:

    That thing is still working..... just tried it, lipo battery still active after 2015?
    PIC has a very low off current, one button selects multiple states, on, brightness slowly going up in steps, brightness slowing going down in steps, off

    Yes and we use rectangular symbols for resistors...

    When resistors are a box with text and capacitors are a box with text
    and IC's are a box with text, the diagram becomes very difficult to read quickly.

    The old Dutch diagrams used a squared zigzag line as a resistor (the
    symbol was later reserved for non-inductive resistors). I prefer the
    old Dutch/German symbol for electrolytic capacitors, as it is not easy
    to work out which way around the British Standard symbol is supposed to
    be.


    Took me a while.. You drive the transformers from the emitters... interesting.

    The drive voltage is relative to the induced voltage on the transformer primaries (the yellow squares on the leftmost windings) so the TIP31A's
    act as comparators with the voltage across the DC resistance of the
    transformer winding in the emitters of the 2N3055's and ignore the
    signal voltages across the inductance of the windings. They turn on
    enough current to give a follower action, so each triple is effectively *current* driving its output transformer winding and the triples can all
    be connected in parallel.

    This arrangement uses the DC resistance of the output transformer
    winding as its current sensing, which avoids the losses of emitter
    resistors. It also means that clipping the drive voltage (the red LEDs
    marked "current clamp") automatically limits the peak current which the
    triples are required to deliver.

    The outer feedback loop then controls the output voltage, so it looks
    like a low impedance source at the output terminals. Normally, having
    two transformers inside a feedback loop is a bad thing because of the
    phase shifts, but the quadrifilar 1:1 driver transformer with its
    capacitors could also be regarded as two centre-tapped chokes; any HF
    phase shifts are well outside the audio band. The feedback is therefore
    mainly limited by the phase shifts in the output transformer, which are minimised by interleaving.

    I used some integrated amplifiers to drive individual loudspeaker units
    in a big monitor speaker system. The data sheet said they did not need
    Zobel networks on the loudspeaker connections, so I didn't provide any.
    After a while there was the most terrible distortion and bursts of
    oscillation. It turned out that the bandwidth of the amplifier was only
    good enough for stability if you ran it on the highest possible supply
    rails, I had de-rated it so the phase shifts had increased and it became unstable. The second printing of the data sheet showed a Zobel network
    was necessary.

    We assign a drawing number to any breadboard, prototype, or

    and test results. The physical proro is marked with that drawing
    number. We have 436 folders in J:\Protos\ as of today.

    Our material control system allows for a <stock number> PDATA folder,
    where we stash data sheets, pictures, notes, test results, links, and
    maybe a pointer to a Protos folder. We have 2644 PDATA folders out of
    almost 8K different parts.

    All this is immensely valuable.

    Dropbox is free and a handy way to back up files, and to make public
    links. Just take a pic of a schematic or a board.

    Putting them on a website (even a private one) lets you make a permanent
    copy on archive.org, so that stuff doesn't get lost as easily. Does
    that work with Dropbox?

    I hope not. Most of my Dropbox files are private, unless I furnish a
    public link.

    How much of that is spam?

    I recently became thoroughly fed up, and started filtering all
    messages originating from googlegroups out of my small leafnode-
    type feed.

    The total traffic in most newgroups which still had any, dropped
    by about 90%.

    I don't doubt I'm missing a few interesting messages posted by a
    few interesting humans... but the massive reduction in spam seems
    a worthwhile price to pay.

    It will be interesting to see if the volume and quality of USENET
    traffic ever starts to recover from the damage done by Google's
    largely-unmanaged flooding from googlegroups.

    ;)

    It’s the public links we’re discussing, unless of course you feel that the traffic level here has fallen beneath notice.

    Does archive.org save them if you ask them to? I do that routinely for
    links that I want to see preserved (mine and others’).

    Cheers

    An other alternative is groups.io
    I am subscribed to one of their groups, but not active there ATM.


    A possible replacement to a usenet group would be a mailing list.
    Most of us do have a domain and could host it. It won't be as free
    as usenet as the hosting person(s) will have control - and also
    plenty of work on their hands to fend off the spammers who are trying
    to kill this group (they tried CAE, too, saw no traffic there and
    let it go).

    None of that is viable. Something done by a willing individual is
    vulnerable; it has to be done by some organization that doesn't depend
    on an individual and thus has a chance to perdure.

    And it has to be better than the existing Usenet.
