Explain for ungenau.

this Heathkit DMM have a Gas lamp for 1 and 2 Nixies. So the overflow is at #199
means when you want to check the AC Voltage what is 230V you have to select 1kV (yes it have  )
and the display will show you "23" ±1 digit. = ungenau
it`s not a bug, it`s a feature 

Yep, got the same one.

so.  on the 20V scale it goes to 19.9 and then what?  does something else light up to indicate an overflow?

using a neon as a "1" is pure genius.  (cheap ass but genius).  have never seen it on an HP thats for sure.

How about a Fluke 8120/8125? Notice the subtle difference between the leading 1 and the others.

Never thought of Fluke as "cheap", especially the military 8125A shown

well my $30 offer on that $45 hp 6227b just expired with no response from the seller.

thought he might at least counter offer at 35 or 40.

was my offer so low as to be offensive?  did not mean for that to happen.....thought it was just part of the bargaining process.

No I think it was a fair offer. Not sure why some of them add the option to receive offer and just don't answer ?

A lot of sellers are like that or are victims of the “ebay turns offers on automatically” shit.

Well just had a fun five minutes. was going to bid on an Elecraft K1 and the sodding connection lagged out because the kids are watching Netflix. Missed it by 2 seconds 

Edit: fuck iOS autocomplete making me sound like an idiot.

well sure.  fluke did a good job of using a neon that matched the size and shape of the nixies.  med's griefkit looks like someone just whacked in the first neon they found.  and it works just fine, but it looks a little......... off.

truth be told, it looks like something i would do.........and i am a jackwagon.


edit   jackwagon - a jack wagon in a mule train was a freight wagon made up parts that were substandard or cannibalized from other broken-down wagons.

Thought you were using Ebay API to script some stuff (mostly search ?). can you just make your own sniping tool ? Would be interesting to combine searching to sniping

My children have a special VLAN for Netflixing, without v6 routing (because Netflix refuses service to Hurricane Electric tunnel users) that on wireless (they've never really cared for wired networks) has its service quality set to one step below the grown-ups Wi-Fi (which also has v6 and public v4 addresses, because I can.).  As soon as the supply of round tuits replenishes, I'll inject a WAN emulator that makes the connection have 600ms RTT and 10% packet loss from just before bedtime until after they've gone to school.

Therein I think lies the humor... this guy is willing to brave the horrors of Scripting Host (or some other similarly Cthulhu-descendant environment) to automate his SEARCH for fleaBay treasure... but NOT the 5 minute Gixen registration (which admittedly, does require that you turn down several politely-phrased requests to upgrade to mirror service) process that would automate the BIDDING process AND have it all operating "set it and forget it" worry-free.

Remember that 12th Commandment...? "Masochism is endemic, perhaps even mandatory."

That was a fixed price offer, not an auction, right?

@mnem: I did actually write my own gixen class module for it but I don’t trust it to spend my money  . Search has a human step.

@Kosmic: Turned it off now. Too much hassle and distraction! Trying to remain focused
 
Random question: has anyone used a Condor branded embedded linear power supply? There’s a cheap 24v unit @ 3.6A going and I’m thinking of grabbing it for HF PA stuff.  I can crank it up to 28V DC out. Looks like generic Lm723 design.  It’s cheaper than buying the damn transformer on its own.

[mnementh]

Sounds to me like you just answered your own question... As long as nobody sees your post and decides they need that PSU more than you.

Pssst... Gixen also allows you to set up bids in a GROUP... so that if you win ANY ONE item in a group, all the others in that group are cancelled. That's really good for cheap-arse dwagons like me.

*back to my tinkery*

[Neomys Sapiens]

@freqq: did you really have nothing but the midget HP as a power supply? Sorry, but I think you are pulling our legs, aren't you?


ok.  in the spirit of full disclosure i will embarrass myself.

in addition to the tiny hp there is a box of assorted junk raped out of old pc's, and one ancient dinosaur (new jersey electronics?  who the hell were they?)

that is the sum total of my power supply resources.  shameful isn't it?

it may get me shunned,  but it feels good to be out of the closet.

We know the actual truth you couldn't find one with Nixies you liked  Of all the test gear PS's seemed to just jump from Analog to LED to VFD's and skipped Nixies. 

Indeed I have not seen any. But as we all know, that doesn't mean much. Even without the self-builds. Just to be complete, I don't know of a power supply using 'decadic lamp array', decatron, plasma display either. Not so sure about VF. I have a concept drawing for one using a large 10/30-scaled instrument and a two-line VF. But it's unbuilt.
@freqq: those small nixies from clocks etc, they would somehow fit in the usual cutouts. So that should not be a hindrance.

[Neomys Sapiens]

And all this talk about -hp- 6227b's! Like I needed to know of it's existence! And that it has the same form factor as the HP6114A and HP6825A. Arrrgh!

Not with my -hp- experiences in the last year. I was looking for the speciall Oltronix as a dedicated non-TM500 symmetrical supply. Wayyy smaller. Except if the 6825 can be conjured back to life and the 6114 turns out fine, maybe?

So the provocation to freqq has backfired all the way.

For what it's worth, at my old job we used to use tons of Condor linear supplies; they were going into 6kW industrial microwave power supplies used in the semiconductor industry.  I don't recall any issues with them, and we built hundreds of the generators.  24V@3.6A sounds vaguely familiar, too - might have been one of the ones used in the magnet supply for the maggie.

[Mr. Scram]

Gixen is for cheaters. It takes all the fun out of an auction.

[med6753]

Geez....you make it sound like I turned down the opportunity of a life time.  "Solder school" was something like a 2 hour class during work time.  And this was in the 1970's before SMT. It was all pin thru hole. What the hell were they gonna teach me that I didn't already know? Not much. 

I dunno... maybe why a temp-controlled iron is important...? So you'd put away the firestarter and get a proper station... some time before somebody gave you one as a retirement gift in your old age...?

*frantically looking about for my athletic cup or some similar form of armor*

Did anyone ever tell you that you can be a total pain in the ass at times?  I'll bet this isn't the first time...maybe the 9999th time.   

There were no temp-controlled irons used in that assembly/test area at that time. We had.....

That's it! No fancy shit, no variable temp, no flame throwers. 

And I hope the wrapped up cables annoy the shit out of you so perhaps you'll leave me alone.

But how can you really be sure @med ?  Time to get a calibrated source or meter ....

Spent part of the evening playing with now sharp blades. Brought a set of very poorly sharpened Marples chisels and took to them with stone and then several grades of wet and dry. Still some more to do but the hollows in the faces and the horrid rounding and chips on the tips are now gone not to mention one of them had a small bevel on the back face  .

Is that sandpaper on glass or a huge stone?

How can I remove those images from my mind now that I've been exposed?

i wouldn't worry much about it...

the list of actions that cause human beings to take offense is infinitely long and a surprising number of them are grounded in the belief that the economic value of one's stuff is a reliable proxy for self-worth.  you likely encountered such a person; they are known to frequent ebay, strip clubs and other disreputable places in numbers far exceeding their proportional share of the general population.
