00:41:56 * T3sl4 pokes Ysjoelfir with a sausage
00:42:50 <Ysjoelfir> thats floppy
00:47:57 <Ampera> that means he's not interested in you
00:52:19 <Ampera> you know it's a boring day at work when you're reading the wikipedia page on buckets
00:55:30 <Ysjoelfir> you surely learned a lot?
00:57:18 <Ampera> about buckets?
00:57:18 <Ampera> yes
00:57:21 <Ampera> leather, metal, wood
00:57:27 <T3sl4> you learned...buckets, you might say
00:57:34 <Ampera> before then I was reading about barrels, which led me to buckets
00:59:56 <T3sl4> ooh, barrels
01:00:01 <T3sl4> barrels are nice, you can stuff a person inside one
01:00:06 <K> one man's barel is another man's bucket
01:00:32 <T3sl4> or even several monkeys
01:00:44 <Ysjoelfir> That reminds me of the day where I was searching for meringue on wiki and ended up at stick grenade
01:01:08 <Ampera> T3sl4, or even a monkey
01:01:12 <Ampera> or multiple monkies

02:20:29 <Kuschelpony> Hello 5V
02:20:59 <Reg7805> how yous doing?
02:21:14 <Ysjoelfir> hey µA7805
02:21:22 <Ampera> https://arstechnica.com/gadgets/2021/05/vulnerability-in-vmware-product-has-severity-rating-of-9-8-out-of-10/
02:21:22 <EEVBot> [Title] - Vulnerability in VMware product has severity rating of 9.8 out of 10 | Ars Technica
02:21:36 <Ampera> Fun day for anyone who deals with vSphere
02:21:55 <Reg7805> i work with proxmox
02:22:16 <Ysjoelfir> whoops Ampera :D
02:22:20 <Reg7805> 9.8 vulnerability
02:22:23 <Reg7805> wow
02:22:30 <Ampera> My servers run on bhyve, my desktop VMs are QEMU/KVM
02:23:06 <Ampera> the number is just a number, it's apparently RCE possible by any arbitrary person to a public facing web interface, to a degree that would allow complete control of the management interface and all VMs on it
02:24:19 <Ysjoelfir> ctrl + a, del
02:24:22 <Reg7805> that is bad, but you wouldnt want to have public facing interface anyway
02:25:03 <Reg7805> im bussy degoogleing my life
02:25:49 <Reg7805> delete everything manual
02:26:06 <Ampera> The intent of the interface, as I understand it, is for it to be public facing
02:26:34 <Ampera> I'm not at the datacenter/office is not a great excuse for not being able to fix a big problem, thus remote access over the web
02:26:49 <Ampera> which is fine so long as you have QA not done by monkeys
02:27:33 <Ampera> I'm not highly familiar with vCenter, I've only used it a few times, so implementations may be different, including another layer in front of the web panel
02:28:35 <Ampera> My management is done over secure shell, and for my servers, I have no graphical management for VMs, so whoever wants to cause harm has to figure out FreeBSD and bhyve, after breaking into ssh
02:29:49 <Reg7805> im sure you use ssh keygen, which make it imposible some one to get from the outside
02:30:15 <Ampera> that's a strange way to say private key auth
02:30:31 <Ampera> which does not make it impossible to get in from the outside, that defeats the purpose of ssh :P
02:31:18 <Reg7805> well of curse, you now what i mean
02:31:58 <Ampera> I do?
02:32:30 <Reg7805> well just menat that some without ssh private key is not getting in
02:32:49 <Ampera> what makes you sure about that?
02:33:59 <Reg7805> as long there is no other vunrabilities and supercomputer
02:34:25 <Ampera> what makes you sure about that?
02:35:41 <Reg7805> just reseach i have done
02:36:07 <Reg7805> im not saying im write
02:36:19 <Ampera> are you saying you're read?
02:37:01 <Reg7805> yes, sorry for bad english
02:37:11 <Ampera> you're welcome
02:38:31 <Reg7805> do you know where to get banking apps apks without googleplay store?
02:39:04 <Reg7805> without usisng apk mirror websites
02:39:29 <Ampera> banking?
02:40:19 <Reg7805> hsbc
02:40:48 <Ampera> only workaround is to own an iPhone and get it off the Apple app store
02:42:29 <Reg7805> sad to see that apps are dependent app stores like google play
02:43:24 <Reg7805> i think i just have minimal install of google crap on phone
02:44:57 <Reg7805> what do you think?
02:45:48 <Ampera> of?
02:48:45 <Reg7805> of usisng minimal install of google requiements
02:50:39 <Ampera> While I have been trying to de-google, I don't hardline it
02:50:53 <Ampera> I work in mobile QA, so I need to use google services no matter what
02:51:31 <Ampera> and phones are so closed to the point some are barely computers anymore, that I feel there's basically nothing you can do besides just not using phones
02:53:53 <Reg7805> well, im trying my best de-google and building my own rom for my phone,
02:54:32 <Reg7805> but seems to be i will be using little bit, which is okey i think
02:55:23 <Reg7805> and my language and writing skills are terrible
02:55:52 <Reg7805> i dont make anyy sense when typing online
03:03:03 <Lord_of_nothing_> hey everyone
03:05:43 <Lord_of_nothing_> Test
03:07:37 <Ysjoelfir> works
03:20:30 <Ysjoelfir> I wonder, has someone seen a... comparison list of communication protocolls/methods for inter-MCU communication? like... I dunno, SPI, UART, PCIe, CAN, whatnot, in terms of max speed, ease of implementation and so on?
03:23:35 <DHess_US> wikipedia has a list of speeds
03:23:45 <Ysjoelfir> do you have a link?
03:24:00 <Ysjoelfir> i looked for it, but didn't find such a list before
03:24:18 <DHess_US> https://en.wikipedia.org/wiki/List_of_interface_bit_rates
03:24:21 <EEVBot> [Title] - List of interface bit rates - Wikipedia
03:24:27 <Ysjoelfir> perfect, thanks
03:24:40 <DHess_US> UART is the easiest
03:24:53 <Ysjoelfir> yeah, but probably a bit slow for what I want to do
03:25:23 <DHess_US> There is no real limit but available devices top out at about 1 Mb/s
03:25:41 <Ysjoelfir> exactly
03:27:38 <Ysjoelfir> I want to transfer ADC values with 10MS/s of 4 ADCs to a main controller, probably an FPGA or an ARM, so UART is probably not in the game ;)
03:28:12 <DHess_US> transfer from what?
03:28:40 <Ysjoelfir> from the ADCs.
03:28:41 <DHess_US> The ADCs will have their own interface and you will be stuck with that.
03:28:50 <DHess_US> ADCs don't use UART anymore.
03:29:28 <DHess_US> Usually they will use some sort of synchronous interface similar to SPI, but there is a more modern replacement for exactly that application.
03:30:27 <Ysjoelfir> I know. I will add a second ARM/MCU/FPGA/Whatnot for every group of two ADCs, which will than communicate with the main chip. and I wonder what interface between those I should choose.
03:34:44 <Lord_of_nothing_> test test test
03:34:51 <Ysjoelfir> still works
03:35:47 <Kuschelpony> yes i see all
03:43:56 <coppice> Ysjoelfir: how far away is the main chip? 10M x (say) 16 bits x 2 is starting to get a bit high for common simple techniques, like cranking up an SPI, unless things are very close together
03:45:05 <Ysjoelfir> roughly 250 meters. :) no, I would say... if I do the layout good maybe like 10 centimeters.

03:46:22 <Ysjoelfir_> meh! stupid disconnect. if that didn;t come through coppice:
03:46:23 <Ysjoelfir_> roughly 250 meters. :) no, I would say... if I do the layout good maybe like 10 centimeters.
03:48:30 <DHess_US> 10 centimeters at 10 MHz is trivial. It is trivial even at 100 MHz.
03:48:59 <coppice> if its all on one well laid out board, with a decent ground plane, just crank up an SPI

03:49:47 <Kuschelpony> hmm, i remember tube VHF tuners that did 200Mhz without a PCB at all, just careful placed wires
03:50:04 <Ysjoelfir> I remember those as well :)
03:50:50 <Kuschelpony> at UHF then everything got more complicated as they used stripline resonators, but VHF was till almost notmal wired
03:51:02 <Kuschelpony> maybe one day i start restorasting the Grundig
03:51:16 <coppice> UHF TV tuners used to be built without a PCB
03:51:32 <coppice> we used to build stuff to run at 2.4GHz without a PCB
03:56:39 <Kuschelpony> thats past what i had in my service technican hands

10:06:06 <T3sl4> that's a fair amount of pressure
10:10:32 <DHess_US> Lol, thought it was thundering outside. It was wind noise from a vblog I was watching through my subwoofer.
10:12:18 <T3sl4> subwoofers are generally not very transparent
10:14:04 <DHess_US> My old one would have thunking noises, but this one is really really good.
10:14:33 <DHess_US> Critical dampening for the win!
10:15:21 <DHess_US> Since when tuned properly the distortion is lower, it doesn't sound "boomy" from intermodulation distortion.
10:15:57 <T3sl4> helps
10:16:23 <DHess_US> I know that is the style most people like, but I hate it. I would much rather the woofer rattle the windows without sounding loud.

11:04:54 <DHess_US> newbie, no, the resistors are selected to achieve the proper attenuation.

11:05:24 <Ampera> checked it out real quick, and it seems to support TLS client certs, which is how I intend to primarily secure my email server
11:05:57 <electrohead> newbie: looking at the schematic for that board - https://i.stack.imgur.com/wJid2.png - you should have no problem with doing that
11:06:10 <Ampera> just need to find a client for Android at some point, and them implement my email setup
11:07:07 <Ampera> Halcyon, want to do a call?
11:07:24 <Halcyon> Yeh I'm just getting ready to go out, I'll call you in 5
11:07:28 <Ampera> alright
11:08:33 <newbie> Thanks electrohead and DHess_US -- I plan to remove the mic and take the audio output directly from this: https://www.ebay.com/itm/310795359575 and input it to the sound detector so I can monitor the off air broadcast of a particular frequency to monitor if the station broadcasts dead air

11:11:57 <newbie> its funny I stocked up on all sorts of modules I never needed at the time thinking that they may be useful for future projects and it just happens that the ones I need I've never ordered
11:12:05 * alfbaz slaps his forhead when he realises he wasn't been spoke too
11:17:09 <newbie> is there any common recommended 3G or 4G module with breakout board that has tx/rx outputs and is commonly used? The ones I see are based on the SIM7000A or SIM7000E

11:46:57 <DHess_US> newbie, there is one caveat with that circuit; it is very sensitive to ground noise.
11:47:22 <DHess_US> To fix that, place the shunt resistance at the microphone input rather than the source.
11:48:10 <DHess_US> If you have like a 3.5mm or 1/4" jack input, put the shunt resistor, or both resistors, inside the plug housing.

11:53:59 <newbie> DHess_US -- thank you. I was also considering a module based on this one: https://www.sparkfun.com/products/12642
11:54:02 <EEVBot> [Title] - SparkFun Sound Detector - SEN-12642 - SparkFun Electronics
11:55:14 <newbie> DHess_US what will the shunt resistor do to the noise?
11:56:32 <DHess_US> The point is that if any current flows through the ground connection, then it makes a voltage across the ground wire from the audio output to the mic input.
11:56:57 <DHess_US> If the shunt resistor is at the audio output, then this ground noise is in series with the mic input.
11:57:14 <DHess_US> If the shunt resistor is moved to the microphone input, then it subtracts that noise.
11:59:55 <newbie> so if I remove the microphone, and replace it with the previous circuit : https://i.stack.imgur.com/CZzHz.gif -- to accept a line level input -- I also need to add an additional resistor as well?
12:04:02 <DHess_US> No, it needs the two resistors as shown. But place the shunt resistor *at* the microphone jack.
12:05:01 <newbie> I was going to put those two resistors at the microphone jack after I remove the mic ...
12:06:42 <newbie> I am not sure where the shunt resistor would go ...
12:07:35 <DHess_US> The shunt resistor is the resistor in parallel with the microphone input.

12:12:55 <newbie> maybe its the diagram that I linked which is worded incorrectly. It says "line in" and "mic out" whereas the way I see it it would be "line out" (coming from the FM module) to "mic in" (going to the sound detector module).
12:13:59 <newbie> wouldn't R2 in this case be considered the shunt resistor? It would be in parallel to the microphone input
12:19:29 <DHess_US> yes
12:21:44 <newbie> so in this case no other resistors are needed other than R1 and R2? at the microphone input?

17:22:17 <rust_collector> oh, ok. have you tried sigrok for that?
17:23:26 <Lemon> nope never, someone told me about but I never tried
17:26:54 <rust_collector> right. I remember trying it for some device, not gpib, but I can not remember what it was. but people seems to use it for all kinds of stuff
17:27:07 <Lord_of_nothing_> I feel so sleepy
17:29:23 <Lemon> seems sigrok is mostly for logic analyzers no ?
17:31:27 <rust_collector> I see it supports at least some bench meters, scopes and so on. i am not sure how well it supports all the things...

18:06:12 <Lemon> hi !
18:06:55 <Ysjoelfir> mornings
18:22:09 <Lemon> hmmm so I read about isolation transformers for USB, and some people said it might be good to use with a logic analyzer, to reduce noise and protect it
18:22:23 <Ysjoelfir> that is true
18:22:39 <Lemon> but I find many different types of isolators
18:22:49 <Lemon> with different prices, ofc
18:23:24 <Lemon> how much cost a usb 3.0 isolator ? if you have any idea
18:25:35 <Lemon> or I guess, I could also use a big one directly plugged to mains, with my computer plugged on it
18:28:01 <rust_collector> I guess that would do the protection part, but maybe not the noise reduction part?
18:28:20 <K> proper usb3.0 isolatir is expensive
18:28:37 <Lemon> yes rusty thats also what I thought
18:28:49 <Lemon> and yeah K looking at those prices, I'd rather save for a big mains one
18:28:56 <Lemon> and protect all my devices at once
18:29:06 <Lemon> but it wont reduce the noise, usb wise
18:29:29 <K> hm what do you mean "noise usb wise"?
18:30:17 <rust_collector> but... i guess you would be looking at digital signals, so I think noise is not as problematic as on analog things, unless you have some BIG noises.
18:30:19 <Lemon> well those usb isolators tend to reduce noise, coming from usb, when you use for example a logic analyzer on your computer
18:30:31 <Lemon> thats also true yes
18:30:41 <Lemon> its mostly for protection
18:31:04 <rust_collector> I would say that is the most important part
18:31:53 <Lemon> yeah I dont want to blow my toys
18:33:00 <Ysjoelfir> its more like... protecting your computer
18:33:37 <Lemon> yeah I count it as a big toy too :>
18:34:06 <Lemon> well the dslogic I bought is protected to a certain extent
18:35:16 <Lemon> I mean, I will use the LA with low voltage stuff
18:35:46 <Lemon> yesterday, looking at a few videos about logic analyzers, a guy was using a logic probe
18:35:53 <Lemon> its quite a cool thing
18:36:54 <K> i would not stress the isolation part
18:37:47 <Lemon> well a guy said, with a usb hub (that is powered via its own power supply) might already be good
18:37:56 <Lemon> as it will fry before the computer, if anything happens
18:38:04 <Lemon> and thats what im using
18:38:48 <K> yes, that should be sufficient
18:39:09 <K> and it is not like you are going to do high voltage
18:39:16 <K> i wouldn't
18:39:33 <Lemon> yes t rue
18:39:37 <Ysjoelfir> there is not that much high voltage logic around, is it?
18:39:51 <Lemon> I guess later I will save for a big mains isolation transformer, for my scopes, and other thingies
18:39:58 <Lemon> but yes the LA will be fine without as you said
18:40:26 <rust_collector> as long as it is not some low voltage signal in some device with ground at 200v.
18:40:46 <Ysjoelfir> thats true
18:41:01 <Lemon> nah I guess I'll use it mainly on stuff powered via usb, or via my supplies
18:41:05 <Lemon> should be fine right ?
18:41:09 <rust_collector> yep
18:41:11 <Ysjoelfir> yez
18:41:29 <Lemon> good good
18:41:44 <Lemon> I bought the dslogic plus and 2x10 clips yesterday
18:42:00 <Lemon> because everybody is saying that the provided clips are trash, and they certainly look like trash
18:42:21 <Lemon> they are super big so not really good to probe smaller ics, and I dont want to buy expensive soic clips
18:42:25 <rust_collector> I think you would figure out that the thing you are working on is "special" and needs research.. so you will be ok
18:42:35 <Lemon> 3m or pomona sell them, 15-30 euros a piece, no thanks
18:43:18 <Lemon> yeah I will take great care, as always
18:43:44 <Lemon> also, the guy with the philips analog meter is pushing me, he offered me a nice price of 40 euros delivered, with 2 probes
18:44:35 <rust_collector> hmmm? analog philips? a multimeter?
18:45:36 <rust_collector> or whatever you call analog meters
18:45:36 <Lemon> https://www.radiomuseum.org/r/philips_electronic_va_meter_pm_2504.html
18:45:38 <Lemon> this one
18:46:46 <Ysjoelfir> thats a philips, so meh :P
18:47:35 <rust_collector> delivered... well... that is not bad. otoh, if philips is bad.... that is a different thing. it is a very meter looking meter
18:48:36 <Lemon> well from what I saw on various forums, its a nice meter, I wanted a bench one for when I need to adjust stuff or look at variations, its always useful, the ones I have need to be used flat which isnt practical
18:48:51 <Lemon> and its a FET meter, so 10Mohm input impedance, which is nice
18:50:23 <Lemon> it can be powered via 6x1.5v batteries or a 9v dc adapter, that I'll need to make
18:50:31 <rust_collector> yeah, analog meters are sort of nice that way. I tend to use the shitty power supply as a voltmeter, for changing voltages.
18:50:59 <Lemon> its practical yeah
18:51:21 <Lemon> this one got tons of ranges, which is also nice, and can read DCI/ACI
18:51:26 <Lemon> most of mine only do ACI
18:51:47 <rust_collector> I wonder about that ref 1v thing on the back. is that to "zero" it to 1v, like the test thing on scopes, or do you hook up an external reference?
18:52:26 <Lemon> yeah I just saw that, im also curious
18:54:17 <Lemon> im always scared about delivery, as those things are fragile
18:54:29 <Lemon> its better with inputs shorted but still
18:54:36 <Lemon> shame theres no binding posts on that one tho
18:54:59 <rust_collector> it has some serious ones on the back
18:56:02 <Lemon> yeah it got a 31.6 amp range
18:56:37 <rust_collector> just to find a nice even number
19:03:18 <Lemon> and that 1V input is to calibrate it, you short it with the ohm one, and adjust it on the 1V range
19:03:20 <Lemon> strange
19:05:40 <Ysjoelfir> *to adjust it
19:05:55 <Ysjoelfir> remember, adjusting != calibrating :D
19:06:07 <Lemon> yesyes sorry, they said calibrating on the manual lol
19:06:30 <Ysjoelfir> see, I knew philips engineers are idiots :P
19:07:51 <Lemon> heh maybe maybe, well tbh tons of brands use "calibrating" instead of adjusting, even good ones x)
19:08:16 <rust_collector> I think I agree with philips and le-mon. imo calibrating needs adjusting, if it is not what it should be
19:09:21 <Lemon> yeah calibrating makes more sense, adjusting should be a synonym
19:09:29 <Lemon> and if you want a check, well, then call it a check :>
19:09:38 <rust_collector> maybe i should start saying that I calibrate the valves on engines I put together. Nono, I did not adjust them, I just measured all of them, and put it on paper
19:09:59 <Ysjoelfir> thats not wrong, rusty. but it is technically not the same. and I would turn your sentence around: You can calibrate without adjusting. but you can't adjust something without having it calibrated before.
19:10:14 <rust_collector> sure
19:10:44 <K> you can adjust and fuck it up even more
19:10:50 <rust_collector> but... some things are useless if they are "calibrated"
19:11:16 <K> imma just turn this lefty a bit, itll make everything more better
19:11:17 <Ysjoelfir> and that procedure you just described is actually pretty common in metrology :) often its enough to know the calibration of a device, you don't NEED to adjust them. but yes, in many (most?) other fields its just of no use.
19:12:00 <rust_collector> right. I have nothing against weird values, but yeah....
19:12:22 <rust_collector> well, not much
19:12:29 <Lemon> https://www.ianjohnston.com/index.php/onlineshop/handheld-precision-digital-voltage-source-2-mini-detail its a neat device

19:14:00 <Ysjoelfir> cute
19:14:02 <Ysjoelfir> but expensive
19:14:30 <Lemon> well thats also what I thought
19:14:39 <Lemon> but after all, it got a superb accuracy
19:15:16 <Ysjoelfir> does it?
19:15:34 <Lemon> 0.0005%
19:15:41 <Lemon> well, typical at 10V
19:15:47 <Lemon> lets say 10ppm
19:16:02 <Ysjoelfir> thats not bad
19:16:26 <Lemon> adjusted with a 3458a, and it got tested by various voltnuts on the forum
19:16:42 <Ysjoelfir> I always wondered...
19:16:54 <Ysjoelfir> how do voltnuts taste?
19:17:21 <K> expensive
19:17:28 <Ysjoelfir> I assumed so
19:17:58 <Lemon> yes, and unsatisfying lol
19:18:07 <Lemon> you always need to add digits
19:18:51 <Lemon> so, what do you think of logic probes ?
19:18:58 <Lemon> it looks to be a neat tool to have
19:19:06 <Lemon> no need to get a dmm, or a LA for simple checks
19:19:18 <Ysjoelfir> its a nice DIY project
19:19:35 <Lemon> thats true yes ! I saw many tutorials
19:19:47 <rust_collector> logic probe....
19:24:35 <rust_collector> I think I like the idea, but I do not do digital things
19:24:48 <K> no digits here boss

19:28:28 <Lemon> they look nice, but I did the right thing by buying the other type
19:28:33 <Lemon> what you got ?
19:29:35 <rust_collector> a yellow envelope it says "resistances"
19:30:06 <rust_collector> I am almost sure it is some of the 431 thingies
19:30:27 <Lemon> ha neat !
19:30:34 <Lemon> they are quite good for what they are, I was surprised
19:31:30 <rust_collector> I am sure they are awesome per dollar, for my kind of no-precision stuff.
19:32:04 <rust_collector> you know, I can get by with a meter with no zeros behind the .
19:32:25 <Lemon> well im more and more going this way too
19:32:30 <rust_collector> but that is hard to find, so I usually get one or two
19:32:32 <Lemon> im quite happy with myu 3.5 digit fluke :>
19:32:48 <Lemon> but those tl431 are quite accurate
19:32:52 <Lemon> stable I mean
19:33:28 <rust_collector> I would think they are pretty good.
19:33:51 <Lemon> you should try to make a precision current/voltage source with those for fun
19:34:03 <Lemon> I will do it too
19:35:08 <Ysjoelfir> didn't you want to do that with the LM399?
19:35:08 <Lemon> and I think I will def get a digital microscope, because shit its so hard to probe those mini ics
19:35:16 <Lemon> yes also :>
19:35:29 <Lemon> but I think its funny to see how accurate you can get it, with cheap things
19:37:40 <rust_collector> I like to see how shit your stuff can be, and still work. but I guess, calling it a precision reference might be a bit much? can we call it a "pretty ok" reference?
19:39:15 <Lemon> hehhh I mean, you can get it stable down to 50uv while its set at 5v, thats quite decent imo
19:40:14 <Lemon> heh I manage to grab a pin of the ADS1256 wiht those mini grabbers, but they are still a tad big
19:40:24 <Lemon> but I need a magnifier for that job lol
19:40:39 <Lemon> they arent really practical
19:40:56 <Lemon> the ones I bought with the LA are as small but you can use them with your thumbs
19:41:10 <Lemon> the one I have right now are straight, so its not easy, but you can fit more I guess
19:42:32 <Lemon> I really want some silicone dupont jumpers tho
19:45:40 <rust_collector> get some silicon jumpers. that is more special
19:52:22 <Halcyon> What have you broken steve30 ?
19:52:22 <steve30> nothing... yet
19:52:22 <K> do you have a short list?
19:52:22 <steve30> i need to go and do grandma's garden, but its raining
19:52:22 <Halcyon> Doesn't sound ideal to be gardening in the rain
19:52:22 <K> indeed
19:52:22 <Ysjoelfir> I found this yesterday. So nice to listen to in the background while doing something you have to concentrate by

19:52:22 <K> something with changing scenery is train rides from drivers cabin
19:52:22 <Ysjoelfir> Is it Halcyon? Well ok, I have it in the background, so I don't realy notice^^

20:01:02 <Lemon> hello frens
20:01:10 <Lemon> USA parcel is here, weeeeeeeee
20:02:15 <rust_collector> wooo?
20:03:13 <Lemon> probemasterrrrr
20:03:30 <rust_collector> eew
20:04:09 <Lemon> well at that point I thought about buying a cheapo dupont crimping tool and make them myself, as its impossible to find
20:04:20 <EEVBot> [Twitter] - eevblog - Laws of gravity still confirmed. The #LunarEclipse has started. https://t.co/txuSiZ9jiZ
20:05:04 <Lemon> and the luxmeter is ready for pickup too :>
20:05:33 <rust_collector> oof, more stuff to do
20:05:43 <K> oh no, not the stuff.
20:06:02 <rust_collector> stuff sucks, if you have to do it
20:07:53 <rust_collector> hmmm. that is an option. but as they are tiny wires, is it really that important? you can get pretty soft non-silicone wires.
20:08:39 <Lemon> well it annoys me to have them all stiff and tangled when you use a lot to connect a board, on the breadboard I will use those jumpers that stay flat from now
20:08:46 <Lemon> but it would be nice to have a couple nice jumpers
20:08:54 <Lemon> woah its really super nice quality
20:09:07 <rust_collector> the stuff?
20:09:22 <Lemon> the good stuff yes
20:09:50 <rust_collector> i thought we told you to buy that a long time ago... why did you wait so long?
20:10:41 <Lemon> well it took about 15 days rusty :>
20:11:11 <Lemon> and good thing, I didnt have any custom fees !
20:11:24 <Lemon> you remember what does it means ?
20:11:32 <rust_collector> I had some cheap ones, that was very floppy flappy, but I think that was mostly because there was almost no wire inside, lol
20:11:34 <rust_collector> yeah, kebab!
20:11:42 <K> yeah like 5 strands
20:11:51 <K> copper clad alu
20:11:59 <Lemon> hmmm not exactly
20:11:59 <K> makes me anger.
20:12:15 <rust_collector> you weird mr
20:12:27 <rust_collector> kebab is good...
20:12:27 <Lemon> yeah I will see what I do
20:12:33 <Lemon> also, heres the microscope I was looking at https://www.youtube.com/watch?v=FYa_biBjJ1E
20:12:34 <Lemon> ho I got a lead forming thingie, I forgot I bought one aswell lol
20:12:34 <EEVBot> [Title] - Youtube: Andonstar AD206 Digital Microscope Review
20:12:36 <Lemon> yeah true
20:12:41 <Lemon> im surprised of what you can get for the price tbh
20:12:53 <Lemon> I thought something like that would cost 2-300 euros if not more
20:13:08 <rust_collector> K I doubt it had 5, lol
20:14:49 <rust_collector> I think most of the negative comments I have seen about the cheaper microscopes, is that they have too much delay.
20:15:14 <Lemon> I tried the tl431 yday btw !
20:15:41 <K> yup
20:15:52 <Lemon> this one seems pretty fine

20:17:14 <rust_collector> I guess, if you want to use it for soldering, or placing something very tiny, it is more of an issue, but if you just want to see the text on some micro-tiny thing, it is fine. I have not seen that one, so, maybe it is fine
20:17:16 <Lemon> I hope he did, or that I wont take fees
20:17:30 <Ampera> good morning Lemon and rusty

20:18:41 <Ampera> don't know what that was about, I quite like puppies and do not wish them to die
20:18:59 <K> maybe it was evil puppy
20:19:19 <Ampera> no it was a very nice golden retriever puppy
20:19:51 <rust_collector> maybe you wanted to dip it in acid, and extract the gold

20:21:45 <Lemon> its the more expensive version
20:22:04 <rust_collector> ok, is it much more?

20:23:54 <Lemon> they look quite identical
20:24:20 * Ampera feeds a cartridge into K's mouth, hits whichever one of his fingers are for play
20:24:33 <rust_collector> it is probably more or less the same, but they can have different sensors or something
20:25:14 <K> what kind of cartridge?
20:26:58 <Ampera> my savings account has made 3.30 USD YTD
20:27:02 <Ampera> I feel rich now
20:27:18 <Lemon> wow ampera enough with the flex, please !
20:27:32 * Ampera flexes Lemon into a nice cup of tea
20:27:35 <Ampera> mmm, lemon tea
20:27:54 <jaymax> What is that after accounting for hyperinflation?
20:28:14 <Ampera> approximately 20 BTC
20:28:21 <jaymax> Bet
20:28:26 <Ampera> a tape cassette cartridge system
20:28:44 <K> ok
20:30:18 <jaymax> Based on the CAD/USD exchange rate channges in the past year, I'd suspect US$2.50. But even then, the Canadian econonomy has got big problems too.

20:41:44 <Ysjoelfir> wait a sec, Ampera
20:41:50 <Ysjoelfir> your savings create money?
20:42:06 <Ampera> barely
20:42:09 <Ysjoelfir> here in europe we have to pay money for the bank to use our money.
20:42:12 <Ampera> lol
20:42:13 <Ysjoelfir> at least in germany
20:42:17 <Ampera> here we have interest in your favor
20:42:31 <Ampera> usually a few cents a year, or maybe a dollar if you have a lot of money in the account
20:42:42 <EEVBot> [Twitter] - eevblog - https://t.co/co8RcfD5EP
20:42:59 <Ampera> long in the ago day, or so I am told, you actually got a lot of money from savings, but I've never experienced such a thing
20:43:21 <Ysjoelfir> we have exactly 0.00%. and if you have over (between 10 to 100k, depending on the bank) on your account you have to pay a "s torage fee"
20:44:10 <Ampera> lol
20:44:23 <Ampera> you don't even pay fees to borrow money on credit cards here, if you pay it back within the month
20:44:44 <rust_collector> same here
20:44:45 <Ampera> in fact, you get more money in rewards from spending it through a credit card than you get from money sitting in a savings account
20:45:18 <Ampera> I've probably earned about 300 bucks through credit card rewards so far
20:45:31 <Ampera> and in terms of rewards, my card is considered good, but not stellar
20:45:54 <rust_collector> i don't even have one
20:46:24 <Ysjoelfir> i think the only credit card that gives you any rewards here in germany is the amazon credit card
20:46:29 <Ampera> it used to be credit cards were also more secure here, as the protections you have against fraud were much better, but I don't think that is the case anymore
20:46:46 <Ampera> that being said, while we might have these splendors, we still have no free means to transfer money besides checks
20:46:50 <Ysjoelfir> all others are either expensive to own or... well, free but more or less limited to a few hundred bucks, maybe 1000
20:47:04 <Ampera> and initiating an ACH transfer is a pain in the ass if you don't know how to do it
20:47:23 <Ampera> reminds me, I need to ask my bank to increase my credit limit
20:47:39 <Ampera> here, so long as there is no regular fee, the more credit cards you have the better
20:47:59 <Ampera> they are one of the simplest and easiest forms of credit information, and having several accounts makes you seem more trustworthy to lenders
20:48:25 <K> new eggs.
20:48:29 <Ysjoelfir> lol
20:49:05 <Ampera> what's even funnier is your credit score is calculated, in part, through what percentage of your available credit you are using
20:49:30 <Ampera> so I have a credit limit on a single card under 2k, and if I take out half of that (which can be just a regular large expense) my FICO8 can drop off by like 50 points
20:50:37 <Ysjoelfir> and over here we have the Schufa. as soon as you get a credit somewhere you get that information added at the schufa register, which some people can request to look into, eg. landlords. the schufa gives you a score. paying your debts lets the score go up, having even a single thing you missed to pay, like, your employer send your money to late and the credit card bill couldn't get paid, you get a very negative point in the schufa register.
20:50:38 <Ysjoelfir> which can result in you not getting a flat or a credit....
20:52:03 <Ampera> savings, they're great :P
20:52:19 <Ampera> as far as I concerned, outside of special deals, credit cards are not to be used for borrowing money
20:52:35 <Ampera> because the interest rates for credit card debt is hilariously high
20:52:55 <jaymax> Cash advances are an immediate penalty here anyway.
20:53:04 <Ampera> oh that's here too
20:53:07 <T3sl4> Ampera: https://i.imgur.com/ZC5JHSH.gif
20:53:12 <Ampera> cash advances are about as bad as you can get for expenses from a card
20:53:23 <EEVBot> [Twitter] - eevblog - #LunarEclipse https://t.co/q5kfUpglb2
20:53:27 <Ampera> no u
20:53:30 <jaymax> So I guess you mean purchases exclusively when "borrowing money"
20:53:35 <Ampera> basically, unless you need 750 bucks now and your checking and savings are drawn, or you'll die, there's no reason to do a cash advance
20:53:51 <Ampera> of course

20:53:55 <EEVBot> [Title] - M1RACLES: M1ssing Register Access Controls Leak EL0 State
20:53:59 <Ampera> anything you do on a credit card is borrowing money
20:54:04 <Ampera> that's the point
20:54:37 <jaymax> Well, almost - you could overpay your bill so there's never a balance due.
20:55:07 <Ampera> I have never done that
20:55:47 <jaymax> That's usually reserved for people fearful that the credit card company will start charging interest on the second day.

20:57:24 <jaymax> I have recently recommended a family member to get a credit card since that person was doing everyone off a single debit card - which is all sorts of problems.
20:57:54 <Ampera> *clears throat*
20:57:56 <Ampera> tiddy
20:58:06 <jaymax> That person was resistant to it because of poor past experience with interest accrual.
20:58:40 <K> where titty?
20:59:05 <Ampera> look down
20:59:10 <jaymax> Ultimately went with a second debit card - which now I need to insist on making purchases on the one that can be "burned" if necessary.
20:59:50 <T3sl4> oh dear, ambulance just pulled up to the neighbors
20:59:55 <T3sl4> an old guy lives there i think

21:00:02 <Ampera> maybe he's just going to work

21:02:40 <T3sl4> understandable, and they have paramedic training
21:02:58 <T3sl4> the hospital is actually like 6 blocks down so it's a pretty good place to have a heart attack, i suppose
21:03:00 <Ampera> and if it's a criminal issue, they have the big fucking truck
21:03:25 <Ampera> yeah we have a hospital right down the street too. We used to live literally down the street from it, which was fun for noise reasons
21:03:27 <T3sl4> and burly strong men and women to drive it
21:03:55 <Ampera> and big sharp objects in the back to remind the potential offenders about the merits of death
21:04:34 <T3sl4> and to make fires question their life choices
21:06:48 <T3sl4> K: oh no, my ELO scores!
21:06:57 <coppice> The best place for a heart attack is about 20cm below your neck
21:07:22 <Ampera> what if you're laying down

21:10:58 <T3sl4> *bwoop**weeeeooooeeeeeooo* and off they go
21:16:42 <Ampera> hahahaha, I thought I was playing an album from the italian winners of the eurovision song contest this year
21:16:53 <Ampera> I'm always amused by what different expenses are categorized as on my credit card statement
21:17:00 <Ampera> then all of a sudden they started singing in french, which was when I realized youtube music was just playing random songs
21:17:05 <Ampera> my order from digikey was categorized as "home repair"
21:17:10 <Ampera> and I literally didn't notice it wasn't the same people

22:02:59 <Lemon> as I didnt eat custom fees for the probemaster set or the fluke, it means I can get a logic analyzer !
22:03:05 <Lemon> well, within the budget, ofc lol
22:03:23 <Lemon> ive been reading a lot, and I think the dslogic plus is the logical choice
22:03:26 <K> which one are you getting?
22:03:40 <K> makes sense
22:03:46 <K> what were other contenders?
22:03:54 <Lemon> im still debatting with myself as I dont know much, but it seems to offer the best ratio price/performance/support etc
22:04:04 <Lemon> well theres those kingst ones
22:04:08 <Lemon> but not a lot of infos
22:04:16 <Lemon> saleae but wayyyy too expensive
22:04:31 <Lemon> analog discovery thingies, also too expensive
22:04:36 <Lemon> and it was missing a few things, I forgot what
22:05:09 <Lemon> couple others, but they either lacked software support or they lacked memory, sample rate... etc
22:05:17 <Lemon> so the dslogic plus seems to be the best option
22:05:37 <K> i would also get one cheap ass 8 channel one
22:05:40 <Lemon> 75-80 euros sounds nice, 20 euros for better clips
22:05:55 <K> fx2la based
22:05:56 <Lemon> I think I have one, well my father had one
22:06:00 <K> ah.
22:06:00 <Lemon> so its probably laying around
22:06:14 <K> that p/p is hard to beat tbh
22:06:24 <rust_collector> 8 small channels for $3 is pretty ok

22:07:04 <K> buckets!
22:07:12 <Lemon> here are the clips I wanted to get, they are much thinier than the ones given in the package
22:07:19 <Lemon> which is a good thing
22:07:46 <Lemon> ez hook stuff or better ones are out of the budget
22:08:10 <K> dunno which ones came with my saleae, but those are good
22:08:49 <Lemon> ez hooks I think
22:08:58 <Lemon> regular micro grabbers but of good quality
22:09:17 <Lemon> I got two that came in the probemaster set, they are nice but a tad too thick for the thiniest ics from what people say
22:09:29 <Lemon> and the equivalent of the cheapo I linked cost 15 euros a piece lol
22:10:04 <Lemon> im mega happy about the probemaster sets
22:10:17 <Lemon> it was a decent amount of money, but I got stuff for my money
22:10:32 <rust_collector> it is ok, it will last for weeks
22:11:30 Quit: Tezzers ([email protected]) Ping timeout: 121 seconds
22:11:48 <Lemon> well, for 120 euros it better last for decades

22:41:21 <rust_collector> and we had all that fun
22:42:00 <T3sl4> wheeeeeeee
22:42:12 <K> it is a bnc to what?
22:42:23 <K> looks like something has sheered off
22:42:38 * Ampera serves split net soup as a consolation price
22:42:40 <Ampera> er, prize
22:42:53 Join: Tezzers_ ([email protected]) to #EEVblog
22:43:34 <rust_collector> I think it is the antenna on cb radios connector, whatever that is called
22:44:08 <rust_collector> but it is like that, pretty sure it is not sheared off
22:44:37 <K> hm, have not seen any connectors like that
22:44:42 * T3sl4 serves Ampera a consolation prince
22:44:53 <Lemon> 98 euros for a dslogic plus, and 20 of those nice little hooks
22:44:54 <T3sl4> it's a stack of pancakes, bitch
22:44:58 <Lemon> that seems acceptable
22:45:00 * Ampera serves T3sl4, watches as the ball bounces and then falls out of the court
22:45:12 <T3sl4> :)

22:46:03 <Lemon> and I expected to pay 40-50 in custom fees for the fluke, and probemaster set...
22:46:08 <Lemon> so all in all, thats great
22:46:23 <K> nop, looks cmopletely foreign to me
22:47:08 <rust_collector> that is probably correct. who would produse these things there?

22:48:15 <Ysjoelfir> weeeee
22:48:16 <rust_collector> that connector has a 6 pin din sort of connector on the middle, and a 3.5mm stereo plug on the end
22:48:39 * Ysjoelfir has Brie from that strange country where they pretend to not understand english
22:48:42 <K> haha
22:48:46 <rust_collector> and that adapter on this end... I have no idea what it comes from
22:50:13 <T3sl4> mmm, cheeze
22:50:24 <Ysjoelfir> yez!
22:50:32 <Lemon> hmmm the dslogic plus is at 149 usd on the website but can be found at 80 euros on aliexpress
22:50:43 <Lemon> it seems to be a genuine one, but I wonder why theres such a difference
22:50:50 <Ysjoelfir> oi! there is one from that strange country!
22:51:14 <rust_collector> BURN HIM!!!!
22:51:23 * Ysjoelfir ignites Lemon
22:51:37 <K> he is a witch?
22:51:40 <Lemon> le strange quoi ??
22:51:56 <rust_collector> yes, he is a witch
22:52:08 <Ysjoelfir> yes K! See, he is doing his magic there, saying some kind of magic formula!
22:52:16 <K> huh
22:52:22 <K> i guess better safe than sorry
22:52:29 <Ysjoelfir> indeed
22:52:35 <rust_collector> floats like a duck
22:53:13 <Lemon> you can't ignite lemons !
22:53:23 <Lemon> thats ethically wrong
22:53:26 <rust_collector> yes you can!
22:53:35 * Ysjoelfir cuts Lemon in half and puts soda on it
22:53:38 <T3sl4> it seems Ysjoelfir has surrendered to the monkey within, and is eating all the cheese
22:53:47 <Lemon> nooooooo
22:54:09 <T3sl4> no cutting! only squeezing!
22:54:54 * Ysjoelfir squeezes hot glue onto lemon and puts the two pieces back together
22:55:07 <Lemon> ok, all good
22:55:35 <Ysjoelfir> in other words.... my systronical Thunder has arrived!
22:56:27 <Lemon> haaaa neat !
22:56:30 <Lemon> you like it ?
22:56:33 <Ysjoelfir> its cute
22:56:37 <Lemon> how big is the dc offset ? XD
22:56:47 <Ysjoelfir> I dunno.
22:57:00 <Lemon> check it, im super curious if it have it
22:57:04 <Ysjoelfir> can't
22:57:11 <Lemon> and if you can also measure the one on your other, not today, when you can
22:57:31 <Lemon> I received my fluke 27/FM yday, and today the probemaster set !
22:57:39 <Lemon> you didnt lie, its super nice quality, im mega happy !
22:58:41 <Ysjoelfir> nah, I can't fire it up as it has some shite mains plug I have never seen.
22:58:55 <Ysjoelfir> and the other one I can't check the offset since the panaplex is fuckered
22:59:58 <Ysjoelfir> but damn that frenchistonian brie is good.
23:00:01 <Lemon> awww crap
23:00:09 <Lemon> heh yes its good :>
23:00:14 <Lemon> not my favourite but its great
23:00:26 <Lemon> do you have any experience with logic analyzers ?
23:01:12 <Ysjoelfir> not that many. I have a totally legit saleaeaea or however you spell that
23:01:19 <Ysjoelfir> wh9ich i used... once
23:01:47 <Ysjoelfir> but I will probably need it soon way more
23:02:28 <Lemon> ha neat !
23:02:37 <K> saleaeaeaeeee!
23:02:37 <rust_collector> i think I will spell it saleæ
23:02:53 <Lemon> I want one to learn about decoding, and understand adcs, and various thingies a bit more
23:02:55 <Ysjoelfir> I agree with rustys spekking
23:02:58 <Ysjoelfir> spelling
23:03:13 <Lemon> when I take arduino code or simply look at datasheet it makes no sense to me
23:03:24 <Lemon> so with a LA I could visualize it, and learn it
23:03:41 <Ysjoelfir> you should get a good old stand alone logic analyzer
23:03:43 <Lemon> and its a cool thing to have ! I will probably get a dslogic plus, it got good specs and its not super expensive
23:03:47 <Ysjoelfir> I always wanted one of those.
23:03:58 <Lemon> yeah a TLA7XX or a 1670G :>
23:04:02 <K> dunno, for arduinos usb ones make more sense
23:04:06 <Lemon> issue is flying leads, they cost a shitton
23:04:24 <Lemon> but sadly most of those dont have much memory
23:04:29 <Lemon> from what I understand it limits them
23:04:34 <rust_collector> anything flying is expensive
23:04:37 <K> they used one very nice looking in curios marc videos
23:04:39 <Lemon> but its good for older stuff, as it got 3243243 channels
23:04:46 <Lemon> a 1670G !
23:04:53 <Lemon> it seems to be an industry standard

23:05:26 <EEVBot> [Title] - Youtube: HP 9825 Repair Part 3: HP Logic Analyzer to the Rescue
23:05:28 <Ysjoelfir> K - absolutely right. I just like the old ones, but they have no real place today anymor. though I would want one when I start programming my power analyzer, as those old ones are pretty good at decoding GPIB
23:06:09 <Lemon> yeah for older things they are kings
23:06:31 <Lemon> I prefer to start with that dslogic, its decently cheap, doesnt take space, and it got a well documented software
23:06:45 <Lemon> for 100 euros I get it along with 20 better clips
23:06:51 <rust_collector> did you order it yet?
23:06:54 <Lemon> because the ones included are shit, according to many people
23:06:59 <Lemon> im about to do it yeah
23:07:07 <rust_collector> good, get it done
23:07:16 <Ysjoelfir> why not go with the saleæ?
23:07:16 <Lemon> lol why you always push me rusty :P
23:07:25 <Ysjoelfir> its 7.82 from banggood
23:07:26 <rust_collector> he is too cheap
23:07:39 <K> when building deubbing your own stuff it is often more convenient to just use pin header here and there
23:07:44 <Lemon> because it cost a shitton Ysjoelfir, if I want the one equivalent to the dslogic its like 6-7 times the price
23:07:47 <K> debubber!
23:08:03 <Ysjoelfir> https://www.banggood.com/de/USB-Logic-Analyzer-24M-8CH-Microcontroller-ARM-FPGA-Debug-Tool-p-1177821.html is it, lemon?
23:08:04 <Lemon> K thats true yeah I ordered a few clamps, SOIC 8/16 for example
23:08:05 <EEVBot> [Title] - Usb logic analyzer 24m 8ch microcontroller arm fpga debug tool Sale - Banggood.com
23:08:16 <Lemon> ha but thats not a saleae !
23:08:25 <Ysjoelfir> lol K :D I should add "debubbing" into my wordings
23:08:28 <Lemon> thats el cheapo :>
23:08:35 <Lemon> certainly super good price.perf tho
23:08:37 <K> it is adequate
23:08:48 <rust_collector> yes, it is cheap, and does the same as a very old saleæ
23:08:53 <Ysjoelfir> Lemon, is it not? but that works with the saleaaeaeaeae software, so it "has to be genuine", right?
23:09:00 <rust_collector> can use the same software too
23:09:21 <Lemon> well no its not a saleae :P but it does work with the software, or sigrok I guess
23:09:27 <Ysjoelfir> though I agree, IF I would have the money I would go for the genuine one to support the manufacturer. but I am poor...
23:09:35 <K> but be aware, that newer cheap 8-channel LA's use different version of fx2la chip and are not compatible with saleae software
23:09:44 <rust_collector> it works fine in sigrok
23:09:44 <K> work just fine with pulseview/sigrok though
23:09:48 <Ysjoelfir> good thing that I have an old one^^
23:10:08 <Lemon> I prefer to spend a bit more and get a more capable one, because I dislike buying something cheap, play with it, realize I need more, buy another one etc
23:10:29 <Lemon> and I stopped smoking, so I can allow myself to get it :>
23:10:34 <rust_collector> sure, but you don't need one, so you might as well get a cheap one
23:10:40 <K> i buy 1st one cheap, and then decide if i need top of the line
23:10:48 <Lemon> well technically I dont need anything in my lab
23:10:53 <Lemon> its more a "want" thing
23:10:56 <rust_collector> good plan
23:11:13 <Lemon> well lets say that if I need more than the dslogic plus, I will know it I guess
23:11:30 <Lemon> but 16 channels is already small from what I saw, so 8 might be really hard for some stuff
23:11:38 <Lemon> I remember my father cursing a lot on the 8 channel cheapo he had
23:11:46 <Lemon> but you are right, its enough to learn
23:11:54 <Ysjoelfir> you can get the cheap one with 16 channels, or even two of those!
23:12:00 <rust_collector> well, stop making things so complicated?
23:12:26 <Lemon> my plan was to get the dslogic plus, and if I discover myself a new passion inside the passion, I'll get a better one later :>
23:12:46 <rust_collector> yes yes, go order it...
23:14:17 <Lemon> you are harsh with me rusty :(
23:14:37 <rust_collector> no, I am just tired of hearing about that thing already
23:15:05 <rust_collector> go have your nap, so you can think and order before 5
23:15:07 <Lemon> well, I feel you are tired of hearing about me, more than that thing
23:15:40 <rust_collector> well... when did anyone tell the story of lemon?
23:16:47 <electrohead> o/
23:16:51 <Lemon> when I say that I want to get something, its not necessarly because I "need" it, as im not owning a compagny making money, needing that tool to work better, its more about myself creating a need because I like to add capabilities to my lab, and I appreciate to have new tools to play/learn with
23:17:00 <Lemon> ofc I could get a cheap one, learn with it, do things blabla
23:17:09 <Lemon> or I could buy a high end one and not use it at 1%
23:18:06 <rust_collector> right, did you order?
23:18:19 <Lemon> well I'll just quit talking, understood
23:19:30 <rust_collector> nah, keep talking. you can just have one of the mods ban me slightly again, so I can not annoy you
23:20:32 <Ysjoelfir> naah. we won't ban you. why should we? :)
23:20:44 <rust_collector> eh, why not?
23:21:09 <Ysjoelfir> because we like you?
23:21:15 <rust_collector> arrrgh
23:21:29 <Ysjoelfir> oh ok, I start hating you now, if you prefer :P
23:21:45 <rust_collector> oh good, I almost ignited
