1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
00:03:32 <DHess_US> 9.3 watts maximum, 1.1 watts at minimum brightness which I would say was 5%. Power factor worstened slightly to 70% at minimum bightness.
00:03:51 <DHess_US> So perhapse not as efficient at low powers but difficult to tell.
00:03:52 <T3sl4> wonder what the efficiency is down there
00:04:15 <T3sl4> if it's poor, that would imply my guess at dynamic range is reasonable
00:04:19 <DHess_US> Dunno. I don't have anything handy to measure true intensity. I dont' think my camera will do it.
00:04:25 <T3sl4> if less encouraging for efficiency, but eh, it's a watt
00:04:31 <DHess_US> Exactly
00:05:03 <DHess_US> Oh, except the variac itself draws a about a watt of VAR.
00:05:15 <DHess_US> So it was *below* 1 watt, perhapse 0.2 watts.
00:05:44 <DHess_US> Can't put the kill-o-watt on the output because it stops working at about 60 volts.
00:06:10 <DHess_US> So I'd say efficiency even at low power is high.
00:07:14 <DHess_US> I stuck a tiny (2 amp) variac into an outlet box for another purpose.
00:07:34 <T3sl4> hah, that makes more sense
00:07:36 <DHess_US> Well, another purpose for now. Later I was goign to use it to dim LED lights.
00:08:07 <DHess_US> It isn't very pretty but it is tough safe with full grounding on the metal enclosure.
00:09:17 <DHess_US> type 10b powerstat which is the smallest they make
00:10:05 <DHess_US> It fits just about right inside of a standard double duplex outlet box with the height module.
00:10:21 <DHess_US> https://www.google.com/search?q=type+10b+powerstat
00:12:37 <DHess_US> What an outlet box extender might look like, https://mobileimages.lowes.com/product/converted/785991/785991167801lg.jpg
00:22:20 <T3sl4> yeah

01:06:12 <T3sl4> yup
01:15:38 <desu> https://www.tradera.com/item/2939/353427132/oml-3m-oscilloskop-bra-skick-
01:17:37 <K> that thing does not do 100MHz
01:17:59 <K> there are very few USSR made scopes that did
01:18:13 <K> afaik
01:19:17 <DHess_US> The USSR made some fast oscilloscopes.
01:19:28 <DHess_US> They even had some analog ones faster than a 1 GHz Tektornix 7104.
01:19:29 <desu> i found a different source saying it does

01:20:27 <K> 10 МГц
01:20:33 <K> 10MHz
01:21:12 <K> DHess_US, those that did do that do not get sold by weight now
01:21:23 <T3sl4> i recall the story went that, they made it like the tek GHz one (no vert amp), but rather than limiting it to a rackmount size chassis as tek equipment had to be, they just made it like two fkn meters long, so the deflection sensitivity was very good
01:21:26 <K> i'd gather most are scraped for precious metals
01:27:54 <desu> 9$though
01:27:57 <desu> that's a good price
01:32:18 <DHess_US> T3sl4, yes but as far as I know, it was otherwise a standard oscilloscope.
01:32:52 <DHess_US> It just had a CRT which was like 3 meters long for increased beam deflection.
01:33:17 <DHess_US> I have the story in my email somewhere if anybody is interested.
01:33:29 <DHess_US> The Soviet oscilloscope wasn't even the most amazing part of the story.
01:34:37 <DHess_US> These are fun also. We've seen a few show up on Ebay. http://w140.com/tekwiki/wiki/Soviet_7000-series_clones
01:35:43 <DHess_US> 250 MHz! http://w140.com/tekwiki/wiki/TR-4658
01:36:51 <T3sl4> wonder if they used more tubes
01:36:58 <DHess_US> more tubes?
01:37:26 <DHess_US> The mentioned 3 meter long oscilloscope was a contemporary to the Tektronix 7104 and used for the same application of nuclear weapons testing.
01:38:01 <DHess_US> The Soviet oscilloscope was significantly faster than the 7104.
01:38:34 <DHess_US> But the 7104 was designed to meet requirements which included being able to fit into a standard equipment rack.
01:39:06 <DHess_US> I'll find the email. It is amusing.
01:41:11 <DHess_US> Ah, it wasn't in comparison to the 7104 directly. I think they were actually scan converter tubes.
01:42:14 <DHess_US> https://pastebin.com/5LtAsb2g
01:43:11 <DHess_US> "When their scientests came here, the researchers at EG&G (who the government contracted to instrument the test shots) assumed that they would be wowed by the 5 GHz digitizers that Tek provided. They were not. Instead of asking how we built such fast digitizers, their only question was how do we drill the holes in the rock for the tunnel so smooth?"
01:46:52 <T3sl4> https://i.imgur.com/VrbALCf.png
01:46:56 <DHess_US> The digitizers they are talkign about were scan converters. They use an oscilloscope CRT to draw onto a semiconductor diode array. This is probably the one being mentioned, http://w140.com/tekwiki/wiki/7250
01:48:31 <DHess_US> I don't remember the details but there was a French company which bought 7104s and other Tektronix instruments and rebuilt them for higher bandwidth.
01:48:36 <DHess_US> I assume that one.
01:49:38 <T3sl4> :D
01:49:39 <T3sl4> yeah
02:09:36 <desu> why would the americans show their bombs to the russians
02:11:36 <DHess_US> They showed their bomb tests to the Soviets.
02:12:04 <DHess_US> As to why, deterance requires that the enemy knows your capabilities.
02:12:37 <DHess_US> In that sort of situation, you want the enemy to know things that you would otherwise keep secret even from your own people.
02:12:42 <DHess_US> It's just game theory.
02:13:21 <DHess_US> Like having diplomats or medical personel be conspicuously disarmed.
02:14:39 <desu> oh
02:14:55 <DHess_US> A modern example where this failed was the war with Iraqu. If we had known Sadam's true capabilites, then there would have been no war.
02:15:17 <DHess_US> Well, the reason for the war would have been different anyway.
02:15:32 <DHess_US> We would have just made up a different excuse.
02:17:29 <DHess_US> What do you mean I cannot have black licorice and Coca Cola for breakfast? Show me where it says I can't!
02:17:43 <desu> bad for you
02:18:07 <DHess_US> But not illegal.
02:18:46 <desu> i would make it illegal if i was in charge
02:18:57 <DHess_US> That's why you aren't in charge.
02:21:25 <desu> i will be one day
02:22:13 <DHess_US> Help, help, I'm being repressed! See the violence inherent in the system?
02:57:20 * T3sl4 distributes a sword to desu
03:15:27 <DHess_US> A man with a sword can beat a man without. A man with a gun can beat 6 men with sword. Any ship with nuclear weapons can beat any planet without.

18:44:56 <K> hello
18:45:41 <DogWomble> hi k :)
18:46:28 <Halcyon> damian, you around?
19:05:54 <damian> sup
19:06:15 <Halcyon> What versions of Windows Server 2016 do you have that you can "lend" me?
19:06:35 <Halcyon> I'm also after Windows 10 LTSC
19:06:39 <damian> so you're after licensing, not ISO's!
19:06:42 <Halcyon> I need to test some monitoring software
19:06:44 <Halcyon> Well, both
19:07:15 <damian> 2016 you can use a trial and you probably won't notice any issues for as long as you use it
19:07:56 <damian> as far as i remember they only block out certain customised features, not the actual use of the software
19:08:03 <Halcyon> It's for me personally, if it works and does what I need it to, the intention is to use it on an on-going basis (at home).
19:08:07 <damian> i used 2016 Standard in production for about four months before i activated the sucker
19:08:14 <Halcyon> I need it to run PRTG
19:08:45 <damian> and LTSC, interesting. why specifically LTSC?
19:09:28 <damian> you know i'm just going to bust your chops about it until i get bored and i'll give you licensing if i have it, right? :P
19:10:00 <Halcyon> I don't need Cortana or all that other garbage, plus Windows 10 updates have been known to break shit
19:10:11 <Halcyon> That's fine :)
19:10:26 <Halcyon> Trust me, if this ran on Linux, I'd be using that instead of MS garbage
19:10:36 <Halcyon> And Windows 2012 R2 is getting a little long in the tooth
19:11:26 <damian> don't i know it
19:11:34 <damian> why specifically prtg?
19:11:57 <Halcyon> It's been something I've been looking at for a while, I like what it claims to do and the features
19:12:00 <Halcyon> Plus it's free
19:12:05 <Halcyon> Unless you can recommend something else
19:12:28 <damian> only free for 100 nodes
19:12:38 <damian> it depends on what you're actually looking at doing with it
19:12:50 <Halcyon> It's only for home, so 100 is plenty
19:13:05 <damian> actually, not 100 nodes, 100 probes
19:13:17 <Halcyon> You mean sensors :P But I'll allow it
19:13:21 <damian> yeah that one
19:13:45 <damian> you think it's enough! but when you start to fly through 30 sensors per machine to check on all hardware components, files and crap it adds up!
19:13:50 <damian> it's been a few years since i've used it
19:14:09 <Halcyon> I need it to monitor a few of my servers, (disk space, NIC usage), UPS stats, pull data from the Ubiquiti server and some other basic ping/networking stats
19:14:15 <damian> plus i am rediculously bad at remembering names for things :|
19:14:43 <Halcyon> I also want to monitor my ISPs CVC
19:14:51 <damian> nice, there's ubiquiti sensors now? or does it just pull snmp data
19:14:55 <Halcyon> Which is just a matter of pulling down their data every 24 hours
19:15:57 <Halcyon> Yeh PRTG comes with a probe specific to UBNT
19:16:14 <Halcyon> Not sure if it's just SNMP, I suspect it probably is?
19:17:20 <Halcyon> It will also do environmental sensors which I'm looking at buying/building
19:17:31 <damian> RE the Windows Updates thing, breaking things is good .. it lets you know that you can release it!
19:17:52 <Halcyon> https://blog.paessler.com/monitoring-ubiquiti-unifi-wifi-with-prtg-total-insight-into-unifi-environments
19:17:54 <damian> but seriously, if you just do two group policies locally on any Windows it'll stop Windows Updates permanently from working
19:18:09 <Halcyon> I don't want to stop Windows updates, I just want the important ones
19:18:18 <Halcyon> I also don't want the bloat of regular Windows 10
19:18:28 <damian> but what if those important ones break your system!

19:20:25 <damian> if you're running the instance of Windows 10 in a VM without Office, the likelyhood of anything breaking from Windows Updates is probably less than 0.5%
19:20:25 <steve30> I finally went swimming
19:20:36 <Halcyon> You say that Damian :P
19:20:42 <Halcyon> But Windows 10 is bullshit
19:20:44 <damian> the issues that usually come up are hardware incompatibilities and office issues
19:20:46 <Halcyon> YAY! Steve
19:21:06 * damian runs almost 300 windows 10 computers and has all of them update from mainstream
19:21:07 <Halcyon> I've seen Windows 10 updates *uninstall* software silently. Just because.
19:21:37 <damian> more likely you've seen Windows 10 bugger up its snapshot so it thinks the software wasn't installed in the first place
19:21:38 <damian> i've had that
19:21:46 <Halcyon> Perhaps
19:21:52 <Halcyon> It's still shit
19:22:01 <damian> all files/folders for the application is still there, but appwiz shows removed and no services, it's weird as hell
19:22:09 <Halcyon> Actually I have Windows 2016 Standard, I'll just use that
19:22:14 <damian> lol
19:22:20 <damian> do you have a license for it?
19:22:38 <damian> legally you're not meant to run Windows 10 in a VM anyway, you're meant to use Windows 2016
19:22:39 <Halcyon> It says I do. I wonder if you gave it to me or I just had it?
19:22:46 <Halcyon> I don't care :)
19:22:51 <damian> i think i gave you one
19:22:54 <Halcyon> It's my farken computer, I'll run what I want
19:23:03 <Halcyon> VM or otherwise
19:23:07 <steve30> The bus I came back on had an LCD monitor on the front window displaying a 4x4 grid of CCTV images from around the bus. How many CCTV cameras does one bus need?
19:23:25 <Halcyon> 4x4 clearly?
19:23:39 <K> 16 cameras?
19:23:43 <damian> 32!
19:23:46 <Halcyon> 64
19:23:50 <damian> but unfortunately that one only has 16
19:23:51 <Halcyon> OK enough now
19:23:58 <damian> what a povo bus
19:24:14 <Halcyon> Did it record to VHS as well ? :P
19:25:03 <Halcyon> Good old time lapse
19:25:06 <Halcyon> Remember that shit?
19:25:13 <damian> how old ARE you man
19:25:17 <Halcyon> 34
19:25:27 <Halcyon> Wait...
19:25:29 <damian> goddamn
19:25:34 <Halcyon> Yeh 34
19:25:41 <Halcyon> I thought it might be 33 but no
19:25:52 <Halcyon> What?
19:26:09 <damian> you old mothafocka
19:26:17 <steve30> Not sure what the purpose of the screen was either. The individual images were too small to see, and the daylight made the screen hard to see.
19:26:42 <Halcyon> If it were at the front of the bus, perhaps to see if anyone was in the way of the door so they don't get trapped?
19:26:42 <damian> scare tactic
19:26:47 <Halcyon> You don't need a lot of detail for that
19:26:54 <steve30> https://www.flickr.com/photos/61188429@N06/40533022333/
19:26:58 <steve30> Its on the upper deck
19:27:10 <damian> same reason Coles has recently started putting live feed cameras in their stores .. the staff don't need it, but the more people know they're being watched the less likely they are to do something stupid
19:28:59 <steve30> Its an ex-London bus so I assume CCTV might be more useful down in somewhere like London.
19:29:03 <Halcyon> It is a deterrent
19:29:18 <Halcyon> And those bus ones are being recorded too, just like trains
19:29:42 <Halcyon> London = Dodgy ?
19:30:31 <steve30> probably, compared to semi-rural Yorkshire.
19:30:43 <K> or Wiggan

19:46:12 <steve30> I hope your boyfriend doesn't mind you fondling other people's bottoms :p
19:48:31 <Halcyon> I hope YOU don't mind
19:48:32 <Halcyon> :)
19:49:11 <damian> i hope your moms dont mind
19:49:16 <damian> bunch of fags
19:49:20 * damian runs
19:49:27 <Halcyon> "Moms"
19:49:36 <Halcyon> Where did you learn to spell?
19:49:53 <damian> i use mom when i'm fake sounding like a douchebag
19:49:56 <damian> so people think i'm american
19:50:14 <Halcyon> I think with your spelling and grammar, they would certainly think that :P

19:52:03 <Guest|23> Hi
19:52:10 <Guest|23> Someone from Austria here?
19:52:52 <steve30> Dunno, but there's a few from Australia
19:52:53 <Halcyon> You mean Australian, not Austria ? :P
19:54:16 <Halcyon> Also Steve: https://www.youtube.com/watch?v=BxbOtpvU2Ck
19:54:22 <Halcyon> This guy is cute as fuck
19:55:48 <steve30> the human or the bird?
19:56:12 <Halcyon> Well both, but the guy mainly. He is totally my type
19:56:33 <Halcyon> Slightly geeky, dark features
19:56:53 <Halcyon> Not too muscled
19:57:26 <steve30> hmm, not my type, although the bird is quite cute
19:57:45 <damian> i prefer girls
19:57:52 <damian> do you have any cute girls with birds
19:58:00 <Halcyon> Pfft
19:58:08 <Halcyon> Who cares? :P
19:58:21 <damian> or at very least female looking transgenders
19:58:36 <Halcyon> Bahahaha
19:58:44 <Halcyon> Not choosy in the slightest are you damian ?
19:59:00 <damian> look
19:59:06 <Halcyon> Toucan's are cute though
19:59:12 <damian> i don't mind there being a cock, but i have to have boobs and a femanine figure
19:59:19 <damian> oh, and a femanine face
19:59:35 <Halcyon> As long as they are a bottom ?
19:59:57 <damian> wat
20:00:11 <Halcyon> Well in terms of sex, what are you going to do with a penis?
20:00:16 <Halcyon> You'll need a hole right?
20:00:26 <damian> that's what the mouth is for
20:00:34 <Halcyon> Eh, suit yourself
20:00:47 <damian> no??
20:00:53 <damian> is that not how it works
20:01:07 <Halcyon> I guess??
20:01:18 <damian> you don't sound too sure
20:01:30 <Halcyon> Oral is fine if they know what their doing
20:01:36 <Halcyon> Otherwise it's the other thing
20:02:01 <Halcyon> Also, you know what else are cute? Otters! https://www.youtube.com/watch?v=z3jojbX-UlM
20:02:03 <damian> even if they don't, it's fun
20:02:04 <Halcyon> I want one
20:02:32 <damian> i saw otters in peru
20:09:33 <steve30> I suggest kittens for cuteness :)
20:09:35 <DHess_US> Keep a close eye on them. Given a chance, otters would kill you and everybody you love.
20:13:55 <Guest|23> do we realy talk about sexual contend?
20:14:11 <steve30> Guest|23, when halcyon is here, yes
20:14:31 <Guest|23> *gg*
20:15:01 <Guest|23> Here in Austria where we have no cangoo (inside joke) its hot enought for ladys to wear flipflops

21:07:57 <Halcyon> But then again, it's on live here quite early in the morning
21:08:03 <steve30> there was a lot of discussion about it in the other channel when it was on
21:08:06 <Halcyon> Yes, I'm aware
21:08:23 <Guest|23> austrian fag...
21:09:06 <Halcyon> Fag is a bit harsh... unless you're actually gay
21:09:19 <Halcyon> It's like black guys using the N-word
21:09:29 <desu> god hates fags
21:09:37 <Guest|23> there is nothing wrong with a nigga
21:09:41 <Halcyon> Thankfully god doesn't exist desu :P
21:09:52 <Guest|23> so i received my lunch
21:09:57 <Guest|23> will talk later
21:10:02 <Halcyon> \o/
21:10:47 <desu> ree
21:10:53 <desu> someone outbid me on that russian oscilloscope
21:10:57 <Halcyon> Oh no
21:11:02 <Halcyon> Which one?
21:11:08 <desu> not paying more than 30$
21:11:11 <desu> https://www.tradera.com/item/2939/353427132/oml-3m-oscilloskop-bra-skick-
21:11:29 <Halcyon> USD$30 ?
21:11:46 <desu> yeah
21:11:51 <desu> well 300 sek
21:11:52 <Halcyon> Yeh I wouldn't either
21:11:56 <desu> which is around 30$
21:11:56 <K> why did you want it?
21:12:04 <K> boat anchor?
21:12:04 <desu> cheap
21:12:14 <desu> i am not rich
21:12:21 <desu> and it's the cheapest i could find that's not chinese
21:13:25 <Halcyon> desu, fair enough
21:13:35 <Halcyon> I would buy old Russian over new Chinese
21:13:41 <K> hmm
21:13:43 <Halcyon> At least it has less chance of catching fire
21:14:20 <K> that might be true
21:14:30 <K> no smps in old ussr gear
21:16:07 <Halcyon> Old, Russian and NUCLEAR... well, that's a different story :P
21:16:16 <Halcyon> Thankfully they don't make those anymore
21:17:27 <DHess_US> Even I wouldn't buy a Soviet oscilloscope.
21:17:44 <Halcyon> Why not DHess_US ?
21:18:02 <DHess_US> When I could find a much better old tektronix?
21:18:06 <Halcyon> Dave's torn down a bunch of old Soviet gear and it seems to be near enough bang-on in terms of spec
21:18:14 <Halcyon> I guess
21:18:16 <desu> shipping is a lot on those
21:18:16 <DHess_US> Yea, but documentation to maintain it?
21:18:19 <desu> to EU
21:18:22 <Halcyon> I should buy a scope one of these days
21:18:30 <Halcyon> It's not as if I haven't needed one
21:19:07 <DHess_US> At least with an old Tektronix it is fully documented and there are lots of spare parts available if needed.
21:19:21 <DHess_US> Well, fully documented not in Russian.
21:19:22 <Halcyon> Actually, DHess_US, for someone like me who needs a scope on the very odd occasion (say a handful of times a year), what would you recommend? Is there a PC/USB based solution which would do?
21:20:11 <Halcyon> I get that it's hard to remain up to date and "relevant" with such low use, but a good all-rounder that is happy to sit on a shelf for months is what I need
21:20:13 <DHess_US> Might get one of those Compsys Design things. They are more for students and USB so require a computer but the cost is right.
21:20:16 <K> desu, look for old hameg
21:20:33 * steve30 likes his Hitachi scope
21:21:09 <DHess_US> If you are up for refurbishing something than an old analog oscilloscope is fine but I don't know your skill level.
21:21:16 <K> dunno if they go for $30 though
21:21:49 <K> desu: https://www.ebay.de/itm/Hameg-Oscilloscope-HM-312-8/372622793543?epid=1826921796&hash=item56c20c9b47:g:GsoAAOSwJItcg7Rb
21:22:17 <desu> no shipping to where i am heh
21:22:32 <K> where is it, if you don't mind?
21:22:33 <desu> but yeah i found a bunch, still a bit expensive for me.
21:22:42 <desu> but ill continue looking and see if one comes around for real cheap
21:22:44 <desu> sweden
21:22:48 <K> i see.
21:23:46 <DHess_US> https://www.syscompdesign.com/products/
21:23:48 <desu> why
21:25:27 <Halcyon> Decent quality DHess_US ?
21:25:32 <Halcyon> I mean, I know they are cheap
21:27:14 <DHess_US> I have no clue. I haven't used one but they look good for the price to me.
21:27:45 <DHess_US> The lowest cost one isn't very fast but the $179 one is decent.
21:28:26 <K> shipping and duties to sweden will make it higher
21:28:53 <K> i would go and ask the seller of that hameg if he can ship to swe
21:31:08 <DHess_US> For casual use I think even a cheap Rigol is too expensive unless you have money to burn or are intended to make good use of it.
21:31:26 <DHess_US> Or find a working oscilloscope locally that you can test before you buy.
21:32:08 <DHess_US> On Ebay you can get a decend rebuilt DSO with warranty for $300 but a cheap Rigol is probably better for most people.

21:33:15 <DHess_US> Keep an eye on sales local to you for a couple months if you live where that short of thing turns up.
21:33:21 <K> desu, arn't there ee related forums in .se ?
21:34:20 <desu> maybe
21:34:28 <desu> probably not that active though
21:35:25 <desu> well there are for sure

21:35:45 <K> tried your lick there?
21:35:50 <K> argh, luck
21:36:06 <desu> nah but i should

21:36:45 <K> DHess_US, problem w Teks in eu genereally is shipping and duties on import
21:37:10 <K> or if you can find some already in eu, the price is way too high for an analog scope, imho
21:37:32 <K> hence my recomendation of hameg
21:37:56 <DHess_US> Example of someone who refurbishes scopes and sells them with a short warranty, https://www.ebay.com/usr/shockcore?_trksid=p2047675.l2559
21:38:14 <DHess_US> K, yea. The US has it easy in that reguard.
21:38:44 <K> those old hamegs aren't that bad
21:38:47 <K> stock components
21:39:10 <DHess_US> I've heard good things about them and old Hitachi scopes.
21:39:37 <DHess_US> In the EU I would expect a lot of those Philips ones. They were good also.

21:43:16 <desu> too old
21:43:19 <desu> but cheap
21:43:27 <K> 1961 eh
21:43:40 <K> might have valves in it hh
21:46:04 <DHess_US> Yea, not *that* old.
21:47:48 <K> fwiw i grew up with this on my fathers bench - https://cs8.pikabu.ru/post_img/big/2016/01/28/11/1454010215172722060.jpg
21:48:18 <K> well, not exactly in that picture, but same model
21:51:21 <DHess_US> Looks like a Soviet copy of something from HP.
21:52:28 <DHess_US> There *are* useful tube oscilloscopes but you still have to refurbish them.
21:52:43 <DHess_US> Like most of the Tektronix 500 series.
21:52:46 <K> yea, it is modular
21:52:52 <K> had several modules
21:52:57 <K> true two beam
21:53:12 <DHess_US> Sure, the Soviets cloned a few US oscilloscopes like that.
21:53:30 <T3sl4> there was a Tek 545 (or 555, i forget) in the physics lab, which i managed to use for one experiment, back in school
21:53:39 <T3sl4> that was fun
21:53:43 <DHess_US> I have a 545
21:53:44 <K> unfortunately it does not work now, either the hv multiplier or something wierd in psu has given
21:53:55 <DHess_US> They are very repairable.
21:54:07 <T3sl4> interesting that the controls changed so much between then, and say, a 475 (which i more or less grew up with), but it's not too awkward, still easy enough to figure out
21:54:08 <DHess_US> A lot of those had bad power supply transformers.
21:54:10 <K> i should fix it :|
21:54:58 <DHess_US> Oh, I don't know about that T3sl4. The only big difference is that the 500 series had stability controls to go with the level control for triggering.
21:55:20 <T3sl4> i think, that was an X-Y plotting experiment, so there was extra interest in using a real CRT over the early rigols that populated the benches in that lab
21:55:49 <T3sl4> i've seen plenty of tube scopes with "stability", but seeing one on a tek just seems so out of place
21:56:03 <DHess_US> I'm not sure when they dropped the stabilty adjustment.
21:56:21 <DHess_US> Triggering on a later model without stablity was much easier to setup.
21:57:04 <DHess_US> Yea, they dropped stablity on the 547
21:58:54 <DHess_US> 545B still had it so the 545 series was probably the last Tektronix scopes with a stability control.
21:59:07 <T3sl4> ah
21:59:26 <DHess_US> My guess is that that was because the following scopes used tunnel diode triggers. The 545 series used comparators.
22:01:41 <coppice_> T3sl4: wouldn't you expect huge changes between a tube and a transistor based scope?
22:02:37 <T3sl4> i should more say, interesting in the ways they changed
22:03:03 <DHess_US> There wasn't except in the circuit details.
22:03:18 <DHess_US> The transistor models which followed the tube models were functionally identical.
22:03:42 <T3sl4> they could've kept things the same, or they could've "done it right the first time", give or take how that affects signal paths, but that's something of a scaling factor in terms of how many tubes you're using, and how hot you're running them
22:04:25 <T3sl4> as for changes, a great many things could've been changed, in a great number of ways; it's more interesting that they made the original choices, and changes, that they did
22:05:01 <DHess_US> At least for Tektronix, the change was only in performance.
22:05:05 <coppice_> The physical contraints on the front panel changed massively in the change from tubes to semiconductors, and that affected the controls a lot
22:05:25 <T3sl4> or simply from a functional standpoint, it's interesting that everything is kind of discombobulated, partly because of the plugin based design and partly because of changes in circuitry and placement, and how that affects where the controls need to go
22:05:37 <DHess_US> The 545 series was the last "all tube" oscilloscope they made but the 547 series which came next was mostly transistors and the scopes are practically identical.
22:06:07 <DHess_US> coppice_, they didn't. 547 was the same size as a 545 but weighed less.
22:06:23 <DHess_US> The font panels still had the same number of controls.
22:06:28 <T3sl4> yeah, they used a lot of hybrid circuits in those transitional days too, and used a lot of transistors in a tubey method (less emphasis on feedback, still using high voltages)
22:06:36 <DHess_US> If you go older, then that was true and the front panels got simpler.
22:07:19 <coppice_> early tube scopes had really funky controls, and the low end scopes even at the time of transition still had funky controls. However, high end tube scopes had pretty well regulated controls by the transition, apart from things like brightness, which still drifted a lot.
22:07:35 <coppice_> the 547 was a kind of transitional fudge
22:07:54 <T3sl4> and then there was HP, who made a scope with a keypad (during a later transitional era, ofc)
22:08:12 <DHess_US> Sure, the 547 was a 545 with lots of transistors and some new functions but basically operated identically.
22:08:31 <coppice_> The scope with the keypad would be an early DSO, right?
22:08:35 <DHess_US> But they kept tubes for a long time after the transition.
22:09:35 <DHess_US> The last tube scope I can think of from Textronix would be the ... 453 in 1965.
22:09:40 <DHess_US> http://w140.com/tekwiki/wiki/453
22:10:07 <DHess_US> It needed tubes for the high voltage rectifiers and for the input impedance buffers because JFETs didn't exist yet.
22:10:35 <DHess_US> So up until high voltage diodes and JFETs were available, everybody was still using tubes for those functions.
22:11:13 <DHess_US> "The 453 is almost entirely solid-state, even in its first version, except for the 5642 HV rectifiers and CRT. Early 453's (below serial number 20,000) used a few 8393 Nuvistor triode tubes. The 453A, introduced in 1971, was fully transistorized,"
22:11:14 <T3sl4> as one does
22:11:34 <coppice_> There were JFETs in 65. MOSFETs came a bit later, but JFETs were established devices by that time
22:11:35 <T3sl4> CRTs still stuck around for a long time, and magnetrons still haven't disappeared [yet]
22:11:48 <DHess_US> But there weren't JFETs suitable for an oscilloscope front end.
22:12:10 <coppice_> There might not have been ones with robust enough protection
22:12:21 <DHess_US> JFETs never had protection.
22:12:38 <DHess_US> Input protection wasn't an issue. All JFETs need it added.
22:13:04 <T3sl4> probably they just didn't have enough gm/C to be competitive
22:13:12 <DHess_US> Yep
22:13:27 <coppice_> er, you might be right. All the JFETs I ever used had shorting clips to be removed after soldering
22:13:38 <DHess_US> Go through the old Tektornix design notes and the JFET figure of merit they discuss is gm/C
22:13:59 <DHess_US> I can even lookup the first good JFET, let's see.
22:15:10 <DHess_US> 2N3684
22:15:25 <DHess_US> Gm/C yields 90 MHz
22:16:20 <coppice_> A TO18 with a shorting clip was quite a PITA to use
22:17:37 <T3sl4> the capacitance was there, but the gain was a decade behind
22:17:58 <T3sl4> ~2mS, comparable to a 12AX7
22:18:04 <coppice_> grammes per coulomb is a odd figure or merit :)
22:18:28 <T3sl4> surely you mean gigameters
22:19:00 <coppice_> not in the 60s. gm was the usual way to write grams. and people usually spelled it grammes
22:19:21 <DHess_US> The 2N3822 (115 MHz) was what Tek actually used in the 453A.
22:19:36 <T3sl4> oi, a wise guy eh? we got Larry, coppice_ and Mho here.
22:20:14 <DHess_US> By the time Tektronix was using JFETs, the JFETs were replacing nuvistors.
22:20:31 <coppice_> Siemens hadn't bribed their way into a unit name back then
22:20:35 <DHess_US> They had a lot of Nuvistor front end vertical amplifiers.
22:21:45 <coppice_> nuvisors were the last refuge of the tube industry in a lot of industrial and military products
22:21:45 <T3sl4> come to think of it, it is rather peculiar to have such a corporate name in the SI
22:22:17 <T3sl4> planar triodes too
22:22:26 <coppice_> T3sl4: yeah, like Tesla
22:22:44 <T3sl4> :D
22:23:05 <T3sl4> although it is peculiar that the Weber does not measure units of heat.
22:24:51 <Guest|23> re
22:24:58 <T3sl4> do
22:25:31 <DHess_US> They kept using Nuvistors for a long time for rugged front end amplifiers and low noise.
22:25:47 <DHess_US> It took a long time for RF transistors to become lower noise than nuvistors.
22:26:14 <DHess_US> Oh, and for radiation resistance.
22:27:27 <DHess_US> TVs used nuvistor front ends for a long time for the first RF amp and mixer.
22:28:02 <DHess_US> They were just the thing for mast mounted RF amplifiers because of their lightning resistance.
22:30:26 <DHess_US> What could prossibly go wrong? https://imgur.com/gallery/1OjJnOl

22:32:07 <T3sl4> those things are nearly all removed from service, and yeah, they do still cause injuries
22:32:59 <spacetechnician> Is anyone here interested in microwave and mm wave SETI?
22:33:19 <coppice_> paternosters are erally good in a company environment. Not so good when the user base doesn't meet constrained criteria
22:33:54 <T3sl4> spacetechnician: yes, though i tend to put them in the kitchen rather than on the furnishings
22:34:23 <spacetechnician> T3sl4: ?

22:35:05 <T3sl4> Settee, SETI?...nevermind
22:35:16 <DHess_US> Apparently one death per year.
22:35:26 <spacetechnician> coppice_: Equipment will be provided. But it seems as though surplus is otherwise scarce in au.
22:35:28 <coppice_> seti - a place to relax and mispell things
22:36:39 <coppice_> SETI has reported no positive results sofa
22:36:42 <DHess_US> spacetechnician, I stop listening after the humans kept sending me penis enlargement spam.
22:37:10 <spacetechnician> coppice_: True, though the Wow! signal is nevertheless a possibility.
22:38:06 <coppice_> A lot depends on the language you use to couch these reports
22:38:18 <spacetechnician> DHess_US: Extraterrestrial biological systems might be asexual, or they might have unbinary sexuality.
22:38:40 <K> DHess_US: it is a bit skechy
22:38:49 <K> about that elevator that is
22:39:00 <K> i've seen and used it
22:39:03 <coppice_> They might have three sexes, making a threesome much less of a thrill than it seems to be for many on Earth
22:39:10 <T3sl4> especially if you wear your tennis shoes onto said elevator
22:39:20 <DHess_US> spacetechnician, that is what was so insulting. They assumed I had a gender.
22:39:24 <spacetechnician> Is there like an amateur radio channel on this IRC network?

22:39:51 <spacetechnician> DHess_US: I have dated a biological female whom is agender.
22:39:52 <coppice_> There was a pasternoster in the building where I had my first job
22:40:04 <spacetechnician> coppice_: In de or something?
22:40:16 <coppice_> in the UK
22:40:45 <DHess_US> I marked there system for redevelopement. The Vogons are going to handle it on Tuesday.
22:40:45 <spacetechnician> sounds like traditional Europe...Pasternosters

22:41:48 <coppice_> I seem to vaguely remember a paternoster in a university building somewhere in the UK. They've never been common, but there must have been quite a few around in the 70s and 80s
22:41:53 <T3sl4> no idea
22:42:14 <Ampera> Halcyon, yer up too early/late :<
22:43:29 <desu> all elevators are kinda scary
22:43:40 <spacetechnician> Eh, physical intrabuilding transport is sorta passe nowadays.
22:44:40 <spacetechnician> unless it's a hospital or some other similar sector that cannot be computerized yet
22:45:07 <DHess_US> I'm not a safety nazi but even I think that is a bad concept.
22:45:17 <desu> replace doctors with robots
22:45:37 <spacetechnician> desu: The robots are still physical and would moreover still need elevators...
22:46:00 <T3sl4> robots don't go home to sleep
22:46:41 <spacetechnician> yes, though they would likely experience breakdowns and require actual maintenance
22:47:00 <T3sl4> if they're broken down, they can't get to the elevators anyway :)
22:47:15 <coppice_> breakdowns? have you seen the mental health figures for human doctors?
22:47:28 <T3sl4> it's not encouraging
22:47:30 <DHess_US> robots are too expensive. Replace doctors with scoops.
22:47:36 <T3sl4> go figure, brains made of meat
22:48:47 <Ampera> I think the guy who did the lobotomy was onto something
22:49:00 <T3sl4> Sheriff Lobotomy?
22:49:16 <Ampera> yeah him
22:51:14 <spacetechnician> coppice_: Heh European universities must be interesting to physically explore...sooo old...
22:51:55 <coppice_> most European universities are not actually that old
22:52:03 <DHess_US> I'm telling you, scoops are the way to go, https://youtu.be/-wa4U6TQlNI?t=18
22:52:15 <DHess_US> And recycling is green.
22:52:38 <desu> ssoy
22:52:48 <spacetechnician> coppice_: I mean, like Oxford.
22:53:01 <T3sl4> DHess_US: our people are our greatest asset
22:53:21 <Ampera> I've walked all around MIT, it has a neat enough campus
22:54:26 <DHess_US> T3sl4, I bet. Have you ever considered how the occupation "Human Resource Manager" is a lot more sinister if you think about it?
22:54:27 <coppice_> spacetechnician: Cambridge is a much nicer place. Oxford (the city) is a bit of post industrial shithole
22:54:43 <spacetechnician> Oxford is second-oldest (1096--1167)
22:55:00 <T3sl4> DHess_US -- I mean, they haven't invented a robotic Resource Manager yet, what're ya gonna do?
22:55:28 <coppice_> spacetechnican: in the UK it is. In Europe several of the oldest universities are in Italy
22:56:33 <coppice_> spacetechnican: I seem to remember the oldest university in Europe is somewhere unexpected, like Pomona

22:59:47 <coppice_> T3sl4: isn't a key aspected of any good university the connections you can make there?
22:59:56 <T3sl4> indeed
23:01:20 <coppice_> I remember things from college like connecting to the mains to a diode, to demonstrate how any diode is really an LED
23:02:06 <T3sl4> it's only an LED for a little while, then it's a DED
23:02:38 <coppice_> true, but had pure white light output in the early 70s
23:03:27 <T3sl4> they even supplied them in convenient ammo reels for continuous feed
23:03:59 <coppice_> true. if only we'd worked on improving the lifetime
23:04:40 <T3sl4> efficiency still wasn't great either
23:04:59 <Ampera> anything is a two way LED if you pump enough energy into it
23:05:27 <T3sl4> Ampera, you're a "let's emit die"
23:06:01 <Ampera> I wanna die

23:08:19 <T3sl4> de ode?
23:14:47 <steve30> hi T3sl4
23:15:12 * T3sl4 meows at steve30
23:16:15 <desu> uwu
23:16:23 <steve30> coppice_, there is a Paternoster lift in the University of Sheffield's Arts Tower building
23:16:35 * T3sl4 scritches desu behind the ear
23:18:09 <coppice_> steve30: still operating today?
23:18:30 <steve30> My Mum did some work there a couple of years ago and she said it was
23:18:53 <steve30> But she didn't use it as she has a phobia of lifts, ever since getting stuck in one (a paternoster) decades ago
23:19:06 <Ampera> how do you get stuck in a paternoster lift
23:19:40 <steve30> well, i think it was a paternoster lift she got stuck in. It probably stopped in an inconvenient place and prevented her from getting out easily.
23:19:43 <coppice_> steve30: That's surprising. Universities are usually a bit anal about health and safety
23:20:01 <Ampera> You could have stopped it at anal
23:20:23 <coppice_> Ampera: I've see people get stuck for a while, out of fear of stepping off.... until the tedium overcomes their phobia
23:23:25 <steve30> https://en.wikipedia.org/wiki/File:Paternoster_Arts_Tower_2013.jpg
23:24:03 <steve30> It has health and safety notices and emergency stop buttons, so probably safe enough. Also apparently it is safe to go over the top and under the bottom.
23:24:44 <desu> do they stop if someone gets sdtuck in the middle?
23:24:48 <desu> or just keep going
23:24:54 <coppice_> of course its safe to go over the top or bottom. people do it all the time, when they miss their floor
23:25:06 <coppice_> The main safety hazard is toe damage
23:25:06 <desu> also what happends if you never step off
23:25:32 <steve30> If you don't get off, you go back down the other side
23:25:47 <desu> cool
23:26:14 <steve30> and then if you don't get off again, you go back up
23:26:42 <coppice_> it just bothers people when they do over the top, as it can be dark and claustrophobic
23:32:43 <Ampera> I remember Tom Scott talking about how going over the top would break the lift when he did a video on it
23:32:50 <Ampera> I guess I was lied to >:(
23:33:41 <steve30> probably depends on the individual lift
23:34:03 <coppice_> rubbish. Its just a bunch of little cars on a band. they are rolling over the top and bottom all the time. There is no lighting in most of them, as without doors they normally really on the room lighting around them
