“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 CZcamsrs. Wry humour, brilliant presentations. Wonderful !
Big same, though 👌
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
Yay, digiiiiits in the morning!
6:36 that giggle 😏
The Japanese didn't count with the German obsession for Lüftung.
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...
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!
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.
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!😊👍🏻😷
Disadvantest 😄
This is out of context, he said: "Slight Disadvantest" ....😂.
Choice
This may not be much, but I truly like your videos. Thank you.
Another first class video. Thanks for sharing my best regards Chris
Your videos are a piece of art.
Finally a new Marco vid 😀
Really, really interesting! Pretty impressive equipment!!! 😃
Stay safe there with your family! 🖖😊
That giggle. When inserting the probe.
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
OMG how did a Marco Reps video get past me... I'd better wear my Biegelehre shirt for this :-)
Wow! I'm looking forward to your HPM7177 video ;)
Oh crap. Why am I up at 03:30AM? Oh ya. A new Marco Reps video. 😁👍
Good Morning, Marco. I've never been this early!
I love the way he talks, is so scientific :D
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.
Amazing and excellent !
Na toll jetzt werden die Advantest auch unbezahlbar
Good morning all!
I’m guessing the epoxied SIP packages are where the tentacles are stored
Mind you, high precision tentacles!
Great device
60th comment and 600th like! Loving the video... All the best CZcamsrs are posting!
i see marco reps, i click, its that simple. period. id.
producing new radiant half bridge circuit videos. tomorrow first release.
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
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
I'm gonna make a "Scandalous" Meme. Thanks for the voice!
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 :)
Hey there, what’s that software you’re using to generate those great plots?
Grafana + InfluxDB + github.com/marcoreps/multiinstrumentalist
I remembered that these were used in ADVANTEST's T667X etc.
Nice to see Grafana usage in the wild. What back-end are you using? PostgreSQL?
That spectrum analyzer is from the same era as the first TFT colour display laptop computers offered by Compaq and IBM.
i love the dry 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.
Oh my my my, how did i miss a marco reps???
i'm waiting for that champion *soon*
careful with those trademark violations
When you mentioned that something was coming up from Cern, you forgot the soon™.
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.
Nice and funny :)
Could you maybe do a video on proper oscilliscope use on your channel?
Would be really interesting hearing your way
nice
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
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!
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.
Haha slight disadvantest.
what is the software you're using for plotting?.
Looks beautiful.
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.
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...
Next Marco Reps Video coming Soon™
Soon™
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...
are you still working on the OSMU?
will we ever see it?
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؟؟
Its been a while bud hope you're doing okay
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
Hey Marco, any update on the OSMU project?
November 10-25... I'm sure the event will last for 16 days... ?
Gimme more cnc videos damnit
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!
are those relays at 8:32. They were super dirty with flux by the looks of it. Would clean with isopropanol or toulene

Soon(TM)
Comment first, watch later
I missed you
Are you getting your very own hadron collider? Hook me up with some of that dark matter!
What is the software you are using to display the data?
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.
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!
How do you use grafana for data plotting?
I wish I could understood these vids, but I watch them anyways
Wie erfasst du deine tollen Grafana-Daten?
Ich hätte jetzt eigentlich Vorlesung, aber...
What GPIB adapter are you using that does not cost 200€?
What's going on with solatron input conectors?
👍
What software is used for these graphs?
Dammit, I was supposed to be going to bed.
Good morning here!
@@lolerie morning here too
How could you lay out so many complex boards without even prototyping?
Y'all Got Any More Of That sub 1k$ 8.5 Digit Multimeters?
Another video? What's next, live streaming?
ELI5 how you’re capturing this data to grafana. Please.
The display looks pretty weak, may need to boost it's negative voltage supply a few volts.
If a German guy is telling me a Japanese device is well made then... 🤯 I want one.
Even though I have absolutely no technical need for one.
Hold up are you the same guy who ran that Kasper minecraft channel?
More digits more tentacles more better!
Why am I watching this at the last day of Feb 2021 and totally missed this deal with 4 layer PCBs? Shame on me for not following my subscribed channels properly. :-(
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.
“I’m expecting supreme build quality”... BODGES!!! nooooouu
So... did it have tentacles?
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!
Many of your video's are unwatchable without a pause key and a skip-10-seconds-back key. I would have totally missed the p p m p p peak 2 peak joke without them. Keep it up and could me in as subscribed.
