A tip for clearing stubborn vias of solder. Grab a toothpick and dip it into molten rosin or any other type of flux. Then apply heat to the via and stick the toothpick in it. Will clear it right up.
I have played a bit with SQUIDS in my last job. Remarkable devices! Ridulous sensitive! After an install of some of our electronics into an old MEG scanner, we gave it a quick test by waving a spanner outside the sheilded room the sensor array was in and it railed the output! Congrats on 100k.
Brilliant - as always ! You might also be interested in the Präcitronic MV40 DC-Milli-Pico-Meter. It's an instrument from the late 60ties made in GDR. It comes with a pA and a 500 Teraohm (!!) measurement range and it's also based on a chopper amplifier. I've repaired and restaurated some MV40, and they're quite fascinating. You can get one for about 30-60 Euro.
Duuuuude, your metrology department is uhh, up to snuff. Holy shit you're flexing that German precision on us :D And rightfully so btw! Congrats on 100K!
there are these rare days when you click a youtube recommendation and it ticks all the boxes! I like it all. The content, and specially you don't dumb stuff down, had some nice trick's in there (gonna use the compressed air solder trick for sure). And an Austrian with a good sens of humor! (are you even allowed to have so much more humor then Germans?) You pack a lot of knowledge in a video so there is something to learn for (I guess) everyone. Today is a good day.
@@reps Yes, it is a self perpetuating hobby per say. I myself use a multimeter for 90% of everything as well. Except when an oscilloscope is needed, or a spectrum analyzer.
A slight correction, a laser pointer in itself produces no heat.. rather it is the interaction of the photons landing on a target surface and absorbing the energy.
I have no idea what any of that stuff is, but I just love the way you show it off I can't help but keep watching your videos. Keep up the good, and entertaining work
That funny reduction geared pot also appears in early Tektronix scopes...and, stacked with another standard pot, for the horizontal position control... Proper press-fit connections are used in automotive applications because they are so very reliable..."proper" ;-)
Marco every video is a treat! I love how each shot is clearly given a bit of thought beforehand. You're always funny and I always learn something - Perfect.
I think Mouser used to carry 0.1% toothpicks, but they discontinued them about five years ago because of low demand. Personally, if you're getting into measurements this serious, spend the extra money and buy Vishay's 0.001% laser-trimmed birch ones.
YAGV... Yet Another Great Video, thanks, love your humor. Next time you do some ultra low voltage measurements, be sure to clean all electric al contact surfaces, back in the day I attended a coax cable connector cleaning course, significant difference between before and after cleaning measurements, often enough to bring an out of spec device into spec.
Very interesting. I’m just glad my applications don’t get anywhere near that realm. By the way, I’ve seen those same pots with the ball bearings in the Comdyna GP6 analog computer.
For cleaning stuff from pcb holes it helps to add new solder (just so that you have a little bump over it) and then put a lot of flux on it (for me those flux pens works best). Then just use braid normally. Edit: Solder pump from the other side if you have access.
The Keithley 2 Pin pure copper connector many years ago Just for the connector was around £200, I used crimped Gold Plated Copper on Silver plated copper PTFE Twisted pair with Silver Screen outer Tufnell Outer wrapped, NO SOLDER used in the UKAS Test Laboratory on Low voltage cable for any DC measurements,
finaly a new vid from you...thanks man...not all of the stuff you are talking about makes totally sense to me but i love watching youre vids anyway...so keep up the good work. oh and gratz for the 100k
Those PCB press fit connectors can be made extremely reliable. EEVBlog 517 was an airbag controller teardown and it used those press fit things. If it's reliable enough for an airbag, they're probably reliable enough for a front panel.
Congrats on the subscriptions. I guess a lot of them are not in electronics; they probably like the way you make boring stuff funny. Besides, the wonderful accent is the cherry on the cake. Keep on the good job.
I could swear you said "fecovolt". That needs to be a unit of measure! Not sure what ASCII char would represent "feco", but could imagine a unicode option.
Did you know about the VEBEG? It's a company that sells stuff from the german government that they don't need any more. They are selling all kinds of things, from tools to cars and even big research Ships. But most importantly they sell measuring equipment and such stuff. At ths time they have a signal generator that has a working range from 10MHz to 20GHz and a frequency analyser that goes down to 10 mikro Hertz
You got to extraordinary measures to find and acquire ghosts for your lab, whereupon you then start chasing them. (Or maybe they chase you!) Well done.
I'm in love with this content, I have a friend that has no Idea of electronics and loves your videos Marco, that says something, how the f**k can you make it so entertaining, amazing repair! Very entertaining
I went through a brief period of volt-nut a few months back, now I have an HP3478 and 4 LM399s, not sure what to do with them and I don't even have a soldering iron yet. Planning on making a small station based on cheap T12 clone tips, but thermocouples, how to get readings from them and your boi, thermal EMF are really confusing me. BTW, the guy that sold me the meter has two of those Keithley 6 1/2 nanovoltmeters, as well as HP 34401s, 3457s, K2000, Tek TDS3052,etc....Have no idea what his job is(won't tell me), but he seems to have access to lots of T&M equipment, industrials electromechanical stuff. Kinda regret buying the 3478 (3.500.000VND or 150USD). Great video, sorry for long post. Greeting from Vietnam.
Hey Marco love your videos, thank you! Which compressor did you buy? Care to share your selection criteria in one of your videos? Thanks for the great content!
Have you checked out SERFs. They are like SQUIDs, but more so, perhaps 10 times more sensitive to magnatism. The word is on the street, that they can detect the magnetic field of a few electrons, perhaps one. They are working on a SERF on a chip.
Hi marko i just tryed ordering a keithley 181 from us. To uk. Git stopped in customs and sent back. How do you manage to get things shipped over from the us to im guessing germany?
@@reps It also splatters the solder a bit. So cleanup afterwards is required. But as a last resort if the wick or the pump doesn't work it's brilliant.

Pin your comment so it shows up at the top! :)
Omg, the onion rings video.. HNGGG.
You're welcome
I never avoided my responsibilities so fast
This channel has it's own section on youtube, no one can compare to this magnificent excellence
This video was entirely worth it just for the air compressor to blow out solder blobs around 11:10, brilliant! Congrats on 100K!
"skillshare" hahah that gave me a good laugh. I think almost every video I watch either mentions skill share or jlcpcb now a days
It's always a good day when you upload a Video Mr Reps! Thank you for taking the time that you do, to do so.

for real tho, whats that even supposed to be?
@@Redh0und The voltage is calculated form those values of the circuit. Its still funny, and the way he said it made it even worse. lol

With every new video, my own lab feels more and more inadequate....
But interesting content as always!
I use my Brymen dmm for everything and the specialized Keithleys only for tasks related to other specialized instruments of questionable necessity

@@reps Yes, it is a self perpetuating hobby per say.

I love theses precision vids and with the lower and lower voltage and current specs of readily available "bits of kit" all the more relevant...cheers!

However on a more serious note, if you have some ideas I could try them for you.
Congrats on 100k subs. And thank you for all your videos. You deserve much more subscribers.
Thanks man
That potentiometer is nothing short of a piece of artwork.
Those Solartron 1081 DMMs are nice, we had one for a UKAS Audit in the UKAS Laboratory
@10:56 A technician at my work told me when you can't get all the solder out it's good to add some additional solder will help to get it out
