Beware of others sneaking up behind you and nudging you into that hole too @Brumby T- 4Hours  :-DD

*@#$$#!!!*^%   

I missed it   :palm:

Been watching it for the last 5 days (including this morning) and remembered 8 minutes too late.   |O 


.... breathe .... breathe ....

It had an opening bid which just sat there from early on.  A sniper came in at 4 seconds left, but didn't throw enough at it, so was unsuccessful.  While I would have sniped too, but at a higher amount, there is still the question of how much the opening bidder set as their max.

It is now time to be philosophical and allow myself to accept the possibility probability(?) that I would not have won the item, but merely have increased the amount the seller received.  <repeat until convinced>

I'm not so upset that I didn't win it - that's always on the cards.  I'm just mightily annoyed I didn't get my arse back in front of the computer in time to play.


Sigh .... It's better to have loved and lost ...    (that's not weird, is it?)

I do have one recent acquisition, though, that may have overdelivered.

Needs a photo (yet to be taken) for a proper introduction.    :-[

I just added a Decade Inductor to complete my RL&C collection lowish offer was accepted  :) Teamed with the 10mH accurate standard our MIA Inverted18650 sent me as a reference point will work well together.

Made by Danbridge out of Denmark nothing known about accuracy or othewrwise.

Tonight I actually read the SMM for the Solartron 7150 Plus meters and it seems I have been under the misapprehension that these beasts could be calibrated using the front panel controls, boy how wrong was I? :palm:

While it is perfectly possible self calibrate these meters if you have the right quality of reference signals, you have to use the GPIB interface, which I don't have so I'll have to live with the slight discrepancies between the readings and in any case they are certainly close enough for my requirements and while I like the allure of more digits on my meters, absolute accuracy is not paramount for me, 3 or 4 decimal places is plenty of resolution for my limited uses.

I have zero interest in falling into the black hole or rabbit hole thank you very much  :-DD :-DD :-DD

For things like this I bought a cheap USB-to-GPIB converter:



Works fine under Linux as a serial device. Haven't done much with it, though. So I don't know if or how the more 'interesting' parts like SRQ are working.

Another day in the Solartron week.

Today we're going to take a look at the 7060.
Despite the name's (can a number even be called a name?) vicinity to the 7061, and a superficially similar appearance, they're not really from the same family.

Let us start with some good points: The power switch is right where it belongs, in a corner at the front. The instrument has (good) feet and a tilt stand.



Yes, this one illuminates the user with a red 7-segment display. As a polite english citizen, it greets him or her with 'HELLO' right after switching it on (not shown here).
What is shown is my now customary 10.0 V reference. Like the 7150's, it has a 6x9 switch. When activated, we get another digit:



And there it stops. When I tried to do the resistance tests, I noticed that all function 'keys' but VDC were marked. Indeed, pressing them elicits a "NO FUNCn" for a short time, and that was that. So this big bloody machine is very close to the A200 - DC volts only. No way it is going to get a space on my measurement wagon, much less the workbench!

Nevertheless, let us take a look at the inside:



The empty space is presumably where the missing functions could be installed, but the person ordering this thing obviously deemed them superfluous.
However, it does have a 'Minate interface' - for whatever that is.

Underneath this interface (consisting mostly of empty PCB space) is the PSU, which has apparently seen some recapping:



A more detailed view of the analogue part:



Not quite as neat as the 7061's, but still very likeable.

I've got no choice: This will go into storage without an attempt to calibrate it (this is also common with the A200: there's absolutely nothing whatsoever to be found about it on the net).

But: The feet, tilt stand and handle might fit with the 7061, which would be most grateful to have them, as it is lacking those!



To be continued ...

Nice looking meter, love the LEDs on the buttons BUT as you said, the other bits to make it a candidate for bench space are missing. Why oh why did have the functions as options, it's like the Flukes of the day, they had current (AC & DC), ACV & Resistance as options WTF.

I think the optional nature of those was a lot of the meters were used as just voltmeters in test systems so it made a higher sales volume due to lower capital cost.

The Heathkit Oscilloscope. It look worst then it is I think. The outside is really dirty. There is rust on the metal part around the screen. Med, if you want it, it's yours. Just cover shipping.



As I thought. Heathkit OL-1 3 inch scope. Thanks for taking the pictures. She's rough but she'll clean up. Obviously every one of those tubular caps will have to be replaced. That's a given. Probably many of the carbon comp resistors have drifted up too. Who ever wired it was kinda sloppy. There's only one thing that concerns me. That's not the original CRT. Original CRT was a 3GP1. That CRT is 3EP1 which I think is Russian. Please do me a favor. For some reason there's masking tape around the base of the CRT. Peel it back and there should be a silver "getter" like the tops of the tubes. Let me know if it's still silver. If it's grey or flaking off the CRT has air in it and no good.

If it's OK let me know how much to ship and I'll send you a postal money order.  :-+

I don't see the typical "getter". Did my best to take some close up pics. Hope you can see something.

I don't either but if the CRT had air in it the glass between the inner coating and the base would be dull so apparently it's OK. Thanks for taking the pictures.  :-+

OK.....I'll take it off your hands. Let me know via PM how much you want for shipping.  :-/O

I may have too. A Tek 1502b TDR came with a precision 3ft 50ohm cable. One is on sale on fleabay for more than I paid for the TDR.
There are lies, damned lies, statistics - and ADC/DAC specs.

It looks strangely edible, while the combination with coffee seems to defer it's very nature and purpose. Generally, I can only advise anyone to be EXTREMELY WARY of german culinary customs north of the river Main!

Speaking of making cakes: here are some examples of my production (this is another hobby of mine)  ;D



And yes, I DO live southern of the river Main.  8)

Thanks. Which is your favourite cake?

Btw, the cake left of the two cheese cream tarts is a roasting apple cake. This cake is the one, which all my friends likes most.  :)

And TEA with some cake is imho always a good idea.  ^-^

Good choice.  :-+  And as a benefit, it contains a reasonable amount of Calvados  8)

Sure the 7150+ can be calibrated via the front panel! See Chapter 5 of the user manual.

It's the 7150 (no plus) which can't be calibrated from the front panel.

I just set a honeycrisp apple pie out to cool and the whole house smells of fructose, flaky butter crust & cinnamon. I'm a horrible cheater though... my local grocery has a half-decent bakery; I buy from them and crisp up the crust in my convection oven when I'm ready to eat it.

Apple pie with a slice of sharp cheddar melted on top & coffee with too much HWC for breakfast... yummmmm.

I LOVE my convection oven, never doubt.  *settles in with a good book*

No, I don't. I'm not good enough for them. But that's okay, because important to me is that the people like my cakes.
My reward is looking on their happy faces. :)

Edit: Just for med: guess, what kind of cake this is:   >:D

Quote from: Ero-Shan on Yesterday at 09:52:05
(And don't ask me what 'GLUG' stands for - I haven't found the definition yet.)


It comes from "a small drink", such as when, if you were passing a mug of beer around and each person took a 'glug' from the mug so as to leave some for the next in line. The best definition by the engineers at Solartron is in this paragraph from the 7075 maintenance manual:



... Some guys' writing was extremely sloppy. They defended themselves by arrogantly proclaiming that their time was immensely valuable, so they couldn't proofread their hogwash or put a little more effort in while writing it in the first place. They thought that 1000 readers spending 2 minutes more each (trying to make out what was meant) was better than 5 minutes of their time. I decided to at least try to do better.

Of course, neither the long forgotten usenet nor this forum is a place for high class literature. I do not expect anyone to go to extremes. A little respect for the reader is all that is needed. We all make mistakes, typos and other blunders (especially those of us with a language barrier), but what I did not find here is disrespect. Thank you all for that!

I salute your dedication to the written word!  :-+

Regardless of where I am writing, I always strive to use both my mother tongue (British English) and my second language (Swedish) to the best of my ability. Those who insult the reader by forcing them to decode badly written, spelled and structured crap, just because "they don't have the time", get ignored.

As you so rightly say, it's about having respect for the reader.

Is it a Publix, by chance?  The Publix here has a great bakery for being in a grocery store.  BU, your work looks fantastic and probably tastes it also.  I am a good cook (not chef) but baking eludes me.  Probably because it is formulaic, where as when I am making Italian food, if the house smells like it did growing up, I have it right.  No recipes, playing with ingredients until it is there.
That which doesn't kill you still requires a co-pay.
