I’ll argue with anyone these days. Fuck ‘em  :-DD

eBay listings done for the day. Thanks to specmaster for the £1 listing reminder. Only computer junk this week.

You haven't got a mono 640x480 STN LCD stashed away by any chance?

Unfortunately nothing that exotic.

Today the Tektronix AFG 1022 arrived.

I saw the parcel and I knew in an instant: crappy packing!
Really, why is it so hard to pack things properly?  :palm:
Even though I've asked the seller nicely to pack it properly and he said, that he will do...  |O



In this plastic bag was the AFG  :palm:



I couldn't see any mechanical damaging and there was also no rattling inside of the device. Uff...
[..]

I've replaced the fuse, now look at this:


Winner winner, chicken dinner! (sort of)

Connected to my scope for some checkings. This revealed that CH2 is sometimes dead. I think, a relay is causing the trouble. If it is working, the output is spot on, like on CH1, which is working flawlessly.

The settings are all the same: 1Vpp, 1MHz, no offset
sine, square, noise and a FFT of the sine output



Will replace the battery next week and investigate, why channel 2 is failing occasionally.

Besides that, I'm a happy camper.  :-+ :D

Oh, mei-oh-mei (packging)!   :palm:
Gladly it came undamaged.  Congrats that the main fault was only that dead fuse.  :-+
Good luck repairing the second channel. I'm crossing fingers you're right and it's only a relay.   :)

If that happens I’ve decided I’m going to be a bastard  :-DD

I would indeed have spent 285 great white pesos for it. Even 300. Buttttt ...

In other news, Mira Furlan, beloved actor playing Delenn, has gone to a place where no shadows fall.

May she rest in peace. :'(

Oh... Bollocks :(

The biohazardous comment was sortof two-part; wristwatches collects gunge, and particularly noxious is the gunge that accumulates in the segments of a metal-banded watch. The bigger the watch, the more gunge. I hate that part of wristwatch maintenance. Just ewwww. And ironically, this kind of chain-link watchband is my most favorite, with the TPU band of the Shine a distant second.

But in all honestly, that comment was mostly directed at the toxic orange anodized face on the one watch. I have a Panasonic Lumix (Think ToughCamera companion to a ToughBook) camera in that color; I literally had to take it off my desk and put it in the drawer because that orange aluminum just constantly distracted me. :-//

The skin under my wedding band had changed color so much that it looked like I was still wearing one. It took years for that to recover.   :phew:

The emotional scars and marks never go away.  :palm:

The word "smegma" (and fridge brand Smeg) spring to mind.

   That adorable little yellow Tek 222PS we were talking aboot a while back closed at $285 Canoodlian shekels with local S/H; while it is an exceptionally nice example, I dunno that I believe it was that nice. That is almost as much as I have tied up in both my 54645A and my brand-new UTG962 arb, even allowing for exchange rate.

I would love to have one of those pip squeaks but they always go for too much coin.

The other thing that puts me off them is the mess the batteries make of them, there was one at work in that state, someone had lost the buttons for the storage too.  :palm:

Anyway I've put a bid on the HP 54615B instead, hopefully the screen fault is repairable.

Today the Tektronix AFG 1022 arrived.

The battery has 0,8V, I'll replace it.


Looks like a rechargeable one.

Yes, you are right!  :-+
I thought, it is one of the usual Lithium knob cells but this one is a MS621FE from Seiko,
which is rechargable. The datasheet is saying, that discharging down to 0V can  be possible.
I'll power-on the AFG1022 tomorrow for some time, hopefully it will come back again.

I simply guessed that from the layout, looked like there's different charge and discharge  paths.

BTW.
This a rechargeable battery, too. Somewhat larger in terms of size and weight, and with built-in controller.

Replace all the electrolytics on the screen assembly and it’ll probably be fine. That looks like it’s lost vsync. That and squashed displays are common problems.

Just to note the calibration is unprotected on that one which indicates futzing.

Also likely derived from the German form of “cunt” (Fotze) which suggests the sort of person who was in the scope already  ;D

Ehhh... it's easy to hit if you take the back off for any reason; if the primate(s) opened it up to see if they could fix the nasty screen, might very well have done it accidentally & cal wasn't effed with.  :-//  And that one has the TETRIS game cartridge installed.  >:D

Hand the current generation an analog clock and ask them to tell you what time it is. It's amazing that many of them can't.

I have 2 analog clocks on the wall in my office.  A 1940's era Seth Thomas Maritime Commission wall clock that needs  a serious mechanical restoration so I only wind it up once in a while.  The other is a cheap as chips 24 hour analog clock.  Drives Mrs. GreyWoolfe crazy and she is the one who is not only a military brat, but her first ex husband was military.  22 years as a ham radio operator and 16 years working for a company that tracks everything in military time, I'm just used to it.

Try to let it run for a day or so, that battery is rechargeable:

I own a Sony digital recording deck (PCM-D50) with such a rechargeable lithium battery that is still powering the RTC after many years.

AM/PM is something I had to start thinking about when I started interacting with people over the Internet. Before that, I was fully immersed in a society where everyone knew and effortlessly (more or less) converted between 12- and 24-hour formats on the fly. I still do. And I don't think Europeans -- as individuals -- are smarter than US citizens. We simply have different kinds of technical debt in our measurement and enumeration systems. And that, I believe, is borne out of the amount of collaboration and central coördination going on in society. I would add the observation that both 24h time labels and metric only have been introduced in the DoD and to some extent in scinence as empirical indicators of the coördination required.

You're right. Use of the 24 hour clock format among the general population is not common here. If I told someone I'd meet them at 18:00 hours (6:00 PM) I would get puzzled looks. 911 emergency dispatch and all police/fire agencies use it and since I do a lot of listening to their transmissions I'm used to it and go back and forth seamlessly.

But I've never had to use a 24 hour analog clock. I'm sure it would take me a few seconds to figure it out.

Tell me, please, how does the average US American react to dates written like 2021-01-24? Having spent far too much of my life using computers to sort and otherwise disentangle dates, I now write it everywhere I'm not specifically required t use another format. Everyone (i.e. ordinary folk) seems to accept it without comment here

Yep, I really don't understand how we started using format month/day/year as apposed to most others year/day/month. If you are involved in international activities you're used to it....like airline pilots for example. But the average Joe Dirt can be very much confused by it and show up for an appointment in the wrong month.  :palm:

I've seen British people confused by 2021-01-24 style dates, it takes some people several minutes to work it out.

Now you're being confused by it. The standard British, and most European country's way of writing the date is year/month/day, not "year/day/month" as you've written.

The ISO date format (YYYY-MM-DD) is, IMNSHO, superior in every regard to all the other ways of writing the date, not least because it has a natural monotonic sorting order if just treated as a decimal number (ignoring the punctuation).

In other news. We're getting what nowadays passes for snow in London. Hardly worth the weather even bothering if that's all it's going to do.
