“I’m expecting supreme build quality” * lowers voice * “and tentacles “
I still remember the day I learned about tentacle porn.
I went straight for the comment section as I heard that. XD
That was epic
I come to these videos for the electronics. I stay for moments like that. And for the electronics. And for tentacles, sometiemes.
Marco Reps and This Old Tony are two of my favourite TH-camrs. Wry humour, brilliant presentations. Wonderful !
Big same, though 👌
The Japanese didn't count with the German obsession for Lüftung.
Yay, digiiiiits in the morning!
Ohhhh an other Reps-Video, NOTHING can stop me from watching that right now!
Wait... 2 bucks for 4-Layer-PCBs? I'll be back in a second :D
6:36 that giggle 😏
In case you missed it...
0:39 "100% chance to win"
2:05 "Tentacles"
2:47 "Hard-earned sponsorship money"
4:21 "Throws up in mouth"
6:37 "ElectroBoom moment"
More subtlety coming SOON™
Giggle at 6:36, as a result of the ElectroBOOM moment
I took 6:36 as a practical implement of the one at 2:05...
OMG you're actually getting one of the HPM7177s from CERN! I've got a couple of AD7177-2's saved for a project myself and super excited to see the test results of those from you to see what they're capable of with proper implementation!
Can’t wait to see you trick out something really wonderful. Whatever it is, I know it will be good! Just know how respected and admired you are by your viewers. You have them entranced. That’s a good thing. Stay safe mates!😊👍🏻😷
I miss all of your great content! Wish you posted more often
I’ve never even used a handheld multimeter. I don’t know why I like these videos so much. Maybe it’s the gloves.
Hello Sir! I just recently discovered your channel and find it facinating! Especially your videos about DMM's, voltage references and related topics. Main reason is probably that I work at a local calibrator manufacturer, although HW design is not my function there.
However, I notice that, based on the words you use related to thermoelectric voltages, that you may have a wrong understanding of that topic. The widespread explanation for thermovoltages is that they are generated at the junction between two different metals, when there is a temperature difference. This is actually wrong.
It is only the temperature difference (or rather the temperature gradient) that generates the voltage, and it can do it along a single material metal wire, for example. The junction(s) only play a secondary role in the system. You may want to read up on this.
I apologize if this was already clear to you, and I misinterpreted you. And again, you make extremely interesting videos!
This may not be much, but I truly like your videos. Thank you.
Another first class video. Thanks for sharing my best regards Chris
I think those are fiber optic cables (possibly with toslink housings, or at least something similar) connecting the in-guard analog section to the digital out-guard section.
Oh crap. Why am I up at 03:30AM? Oh ya. A new Marco Reps video. 😁👍
Your videos are a piece of art.
Really, really interesting! Pretty impressive equipment!!! 😃
Stay safe there with your family! 🖖😊
Good Morning, Marco. I've never been this early!
Hey Marco,
could you please explain how you get all your measurement data into grafana?
What database are you using? Do you think the setup is complex enough for an entire video?
Thank you :)
Disadvantest 😄
This is out of context, he said: "Slight Disadvantest" ....😂.
Choice
Finally a new Marco vid 😀
Nice to see Grafana usage in the wild. What back-end are you using? PostgreSQL?
OMG how did a Marco Reps video get past me... I'd better wear my Biegelehre shirt for this :-)
That giggle. When inserting the probe.
Wow! I'm looking forward to your HPM7177 video ;)
I’m guessing the epoxied SIP packages are where the tentacles are stored
Mind you, high precision tentacles!
Hey there, what’s that software you’re using to generate those great plots?
Grafana + InfluxDB + github.com/marcoreps/multiinstrumentalist
Amazing and excellent !
60th comment and 600th like! Loving the video... All the best TH-camrs are posting!
what is the software you're using for plotting?.
Looks beautiful.
I'm gonna make a "Scandalous" Meme. Thanks for the voice!
Marco if you heat the fluke 5700's VFD filaments to a dull orange with constant current for a few seconds you might be able to rejuvanate the brightness
are those relays at 8:32. They were super dirty with flux by the looks of it. Would clean with isopropanol or toulene
Could you maybe do a video on proper oscilliscope use on your channel?
Would be really interesting hearing your way
i see marco reps, i click, its that simple. period. id.
are you still working on the OSMU?
will we ever see it?
love your channel just wondering how sensitive are these meters to temp change would it be worth it to regulate the temp and humidity in the room you use them or does the heat they produce them selves cause the drift?
Most of the parts and references in nicer machines are built into little hermetically sealed cases or enclosures on the PCB board inside and have built in heaters to keep them at a stable temperature. Most any high-end test equipment (anything over $200-$300) Will start to implement what is called “ovenized“ parts.
So they have built-in heaters to keep them at a constant stable temperature and they’re built into some small hermetically sealed can or plastic insulated package. So pretty much as long as the machines are warmed up… They maintain their metrology grade calibration and statistics. Real nerds like Marco leave their precision equipment powered on 24/7 365 days a year. Because that allows them to maintain the highest level of accuracy. that level of precision is absolutely not needed unless you just enjoy the extra .01% of precision… Or are some big lab like NASA.
That’s how all of the big labs like NASA and places do it. The gear is designed so that once it’s plugged in and turned on… It’s never turned off until they retire that piece of equipment a decade later.
انا من متابعيك شكرا على الفيديو. لكن استفساري الذي يشغل بالي عندما يصنع مقياس من (8.5 digt) هل يعني أن المصنع يجب أن يمتلك جهاز للمقارنة والمعاينة ب (11digt) مثلا؟؟
I love the way he talks, is so scientific :D
i have a question, what is called the bottle you use to dispense the IPA? i want one but i cant find one , thank you!
You sound a lot more excited than your usual underline excitement. Maybe because of the Tentacles?
Inserts Temperature Probe, giggles XD just my kind of humor
You should finally try to get your hands on a Fluke 8508A. The ideal playmate for your equipment. Especially if it has the Rear panel option.
Hey Marco, any update on the OSMU project?
Oh, the good old Elektronica in Munich... In 1996 i got my first blue LED there.
But 2018 was probably my last one, since now around 2000 km is quite a distance, compared to previously driving just 2.5 h. And now i come from a Risikogebiet...
Do not open windows :-p
Good morning all!
What is the software you are using to display the data?
producing new radiant half bridge circuit videos. tomorrow first release.
Na toll jetzt werden die Advantest auch unbezahlbar
November 10-25... I'm sure the event will last for 16 days... ?
Great device
How do you use grafana for data plotting?
That spectrum analyzer is from the same era as the first TFT colour display laptop computers offered by Compaq and IBM.
What's going on with solatron input conectors?
What software is used for these graphs?
i love the dry humor
Wie erfasst du deine tollen Grafana-Daten?
When you mentioned that something was coming up from Cern, you forgot the soon™.
What GPIB adapter are you using that does not cost 200€?
I remembered that these were used in ADVANTEST's T667X etc.
Marco, I admire your passion but for real: For what kind of S(/)=?!" are you *using* those meters? :-D
measuring if the batteries for the TV remote are not empty.
BEST REPLY EVER
So he can use them to measure his other meters!
Oh my my my, how did i miss a marco reps???
There are some people that like weed, there are some people that like cocain and there is this guy, how gets high on digets after the comma...
i'm waiting for that champion *soon*
careful with those trademark violations
Even though the sponsor segment was told in a dry humorous manner and could seem uninteresting to most i must say that the delivery was perfect for sparking the interest of those in the electrical industry. Quick, to the point and entertaining, unlike when companies pay some PR-firm a gazillion (insert money unit here) and they put out an annoying and overproduced ad that is 90% empty bullshit.
How could you lay out so many complex boards without even prototyping?
Are you getting your very own hadron collider? Hook me up with some of that dark matter!
ELI5 how you’re capturing this data to grafana. Please.
Its been a while bud hope you're doing okay
nice
The Prema 6048 would be a good one to look at...if you can find one. I think they were only made for a few years before Prema went bankrupt and left the test equipment industry for good...
Nice and funny :)
Next Marco Reps Video coming Soon™
Here is a link to the schematic: www.eevblog.com/forum/metrology/advantest-r6581-schematic-diagrams/
Haha slight disadvantest.
For any hobbyist that wants one of these, you should be keeping an eye on Yahoo Auctions Japan.
Perhaps every year or so you can find one there for ~USD350ish, and at around that price it's a steal. Normally they're closer to the ~USD1000 mark and I think that's a bit tooooo much unless you're a bit volt-nuts. (better to use that money towards the 3458A fund)
What is the use of one of those for a hobbyist? Except if you want to collect high quality gear.
@@nukularpictures physics experiments
Soon™
Another video? What's next, live streaming?
Yeah... JLC PCB - they were good 2 years ago. Now it's only quantity over quality. They just screwed up one of my projects. They just ignored gerber file with markings for V-CUTs, and supplied panels without them. Now I have 5 panels without ability to snap boards out of them :)
Support is non-existent - they say basically that they give zero f*** about this problem :)
Colleague from work got bitten also maybe week earlier - they made boards without non-plated holes, probably because there were two separate NC files for plated and non-plated. And they just ignored one of them :D
Well I mean you have to see the price. Somehow they have to manage it. But ignoring v-groves is bad. Cutting the fiberglas is nasty.
But the second version when you upload two different files is not the problem form JLC. I mean you can not expect that they will check every upload that closely. It is a cheap service.
For me it is mostly fine. Sometimes they sadly ignore the placed holes for the SMT process and add more right next to the ones I placed but other than that it worked fine.
There is a specifications sheet available from Mickle from the EEVBlog. It is written in Japanese and may provide a guideline. I am surprised about the sensationalism of this video.
For the manual in "a readable language" try ask for one here www.adcmt.com/en/download/ope_discon .
Just specifications check here doc.xdevs.com/docs/Advantest/R6581T/R6581%20manual.pdf the units and number are readable ;)
Hope it helps and keep up the good work!
Soon(TM)
You got a lot of soons this time !
And there are so many more that haven't even made it into the video 🙈
@@reps grrrrrr
Gimme more cnc videos damnit
Anyone got a part number for those spring loaded banana jacks at 6:31 he's using to connect that RTD to the meter?
They’re made by WAGO.
@@tookitogo Thank you so much! It looks to be the Wago 215-212
@@miksu103 no problem!
The display looks pretty weak, may need to boost it's negative voltage supply a few volts.
I wish I could understood these vids, but I watch them anyways
Comment first, watch later
I missed you
So... did it have tentacles?
Hold up are you the same guy who ran that Kasper minecraft channel?
how much
ich verstehe nicht, für was man so eine genauigkeit braucht... kannst du uns normalsterblichen mal bitte erklären für was man das braucht und was du damit machst ???
👍
Anybody know what the 'New Brymen Soon' promotional banner is about at the end of the video? th-cam.com/video/d4LbBeUiUWM/w-d-xo.html
Are Brymen releasing a new multimeter, anything better than the existing BM869? Also what about that new UNI-T meter over on Joe Smith's channel, it appeared in his last video about the new eevblog meter, which also happens to be made by Brymen. When I google the UNI-T model number i cannot find anything about it. So I am speculating it is not released yet either. But looks to be positioned in its price and features as a competitor to the BM869s.
I mean I love high precision test gear just as the next guy, but what the hell do you do with so many of them? I mean really I would not even know where I would use an 8.5 digit multi-meter. Heck even a 6.5digit one is overkill for me. What are your plans with those devices? Just collect them?
Measure references and become an international calibration lab. Obviously. Also, you get an extra digit if you use 2 dmms
@@Cerv3ra Cool so 9.5 digits? :D Basically counting individual electrons at that point.
