I absolutely love the tactical good boy deployment

Give a raise to the person who implemented chapter timestamps on UKposts

Love your new "special" gloves xD 3:09

im being honest here guys. i felt dumber and dumber the more i watch his videos. it is up to a point where i can understand him but i felt like he is a magician with all those results

I think I can speak for everybody here when I say don't worry about the length of your videos. You are either into this kind of thing and are going to watch all the way through (like I do on all your videos) or you're going to change the channel really quick. Just go as long as you think it needs to go. We're all right behind you watching ☺️

Great video. Here are my suggestions, first two are about the low pass filter: 1: You care about time-domain, so you should use Bessel alignment (not Butterworth, although the roll-off looks more attractive, it's resonant, so every 'bump' leaves ringing...), and really get that step response to settle without overshoot. As close to critically-damped as you can. 2: Also, avoid x7r in the frequency-dependant parts of the filter - they don't have linear capacitance vs voltage - you need c0g / np0, and they're big when you need a really low corner frequency. Use arrays of them (as it's easier to achieve the capacitance ratio you'll need for point 1). 3: Consider that 'chopper stabilized' also means 'discrete time'. It's a sampled time system, albeit one sampling over quite long intervals. You'll need a *passive* low pass in front of it to reject signal that might otherwise alias. (because if it does, it will invariably end up all over your base band). Consider that you want as much rejection ratio as you can achieve from half the chop rate up, and especially to suppress each harmonic of the chop frequency. (so, yes, you have to worry about VHF-band behaviour, or, what happens to your op amps at VHF through UHF when you're mostly aiming for low frequency. Worry about unexpected resonances because of things like capacitor resonance. 4:You're trying to avoid making a self-mixing superheterodyne radio receiver - anything beating against itself will end up shifting itself down to right where you don't want it (near 0 Hz). So this means you want all the 'linear' parts of your circuitry to really be linear. (consider what happens in non c0g/np0 dielectrics with voltage...). 5: I have heard that 78xx/79xx fixed voltage types are not particularly great at being low noise - have been told variable types like LM317/337 etc yield lower noise. Could you see if they do? Would *really* love to see whether any of the above made much impact (especially if you could measure it!) - or even better, address why I'm wrong about any of those. Great work!

11:55 launching homing dog-missiles :)

I love these longer videos. They are so *mesmerizing* to watch. Keep making more of them, please! Thank you. 🤗

Alternate title: The Art of Electronics Chapter 8 in a Nutshell

you're a lucky man living so close to such succulent wild capacitor growths! I only get green ceramic caps growing by me :(

Fascinating to see. I've been caught out by battery noise before, you can't trust that chemistry stuff. Oh, and I love the bicycle based terrier launch system, I'd try it myself except I've got a fat border collie that won't fit in a basket!

Gosh! capacitors are already in season. I must go and have a look locally, though whether I'll find any is hard to say - it has been so dry recently.

It's nice to see that you're making full use of your CaSCaDS (Capacitor Sniffing Canine Deployment System) to sniff out rare components in the wild. We have a miniature poodle that was like that but his central guidance computer has become easily corrupted by nearby flowers and passing females. His glory days are over but not forgotten so we just let him lie by his charge port bowl and dream of former conquests in the field.

What a thoroughly enjoyable video. Yet another reason to love the 7805, the toasty hero of the digital world for so many decades! Be interesting to see he noise from those drop-in switcher replacements we're supposed to be stuffing into our vintage gear these days to avoid baking all those elderly caps... (I was exploring noise performance of power sources from a very early age. As a kid, I had a Radio Shack 65-in-1 electronics project kit. It had a little solar cell, and one summer's day I put the crystal earpiece that came with the set across the cell's terminals to see if I could hear anything from the sun. I sat in the field outside the house and - yes! Every so often, an odd, short burst of noise! What new phenomenon had I discovered? How exciting! Further observations revealed that instead of obserivng some mysterious cosmic fusion process, I had found a way to eavesdrop on bumble bees as they flew across the face of the cell. Ah, well.)

please make more of those, incredibly interesting! Ressources about high precision, and more subtle analog electronics are pretty rare

You have an interesting way of soldering SMD stuff without tweezers but poking and shuffling around components with the soldering tip and solder

Dropped everything to watch this. Few things are as soothing as some nice low low digits... what a Balsam für the Seele.

I loved the video. I am mesmerized by what you are able to achieve. Also, the trip to the forest and your commentary puts a smile on my face. Thank you!

This is my favorite video, Marco 👌 I like these project videos where you go from conception to design to build to testing-they're entertaining and educational. Please do more project videos!

What an awesome Video! Really like those almost-esoteric-nanovolts-measurement-things (TM). Tapping on the bench to change the output of a source by some order of magnitude, just absolutely amazing!

I missed you so much Marco (nohomo)

You can ramble on about anything and I'll watch and listen. Thanks for the vid.

Tools for the sake of tools. Love this video. Great mix of good stuff and the welcome humor to make all go down so well. Thank you!

FINALLY A GOOD VIDEO THAT IS WORTH WATCHING

Good stuff. I am having these exact same technical goals now. Thank you for doing my work for me. Best!

I think it's under-appreciated how much work Marco goes into to give us cap plants.

Your videos are never "too Long" and they also never will. I enjoy every second...

Soldering SMD resistors is much easier when you fill one pad with solder, then place the resistor with tweezers and solder it to that pad. Then, when it is placed fine, solder the other side.

I absolutely love the low tech stuff - it's interesting to see what projects you are working on no matter the fanciness

All your videos are great. No matter if it is CNC, laser or electronic projects. Keep up the good work!

What an Amazing Electronics entertainer/educator. Well done Marco!!!

I love these videos Marco. I will never make anything like this but I love watching the process, and I also love your humour

I like seeing these projects, even if you consider them to be boring in comparison its still fun

I love this type of technical videos! Laser stuff and such is flashy and fun, but I prefer the ones that leave me amazed at all the things I have yet to learn!

Thanks for sharing! I love your work and dry sense of humor.

This is one of my favourite vids honestly

The best thing about videos like this Is the dogs They are so well behaved, and great searchers too! Well, and everything else too. Seriously, your videos are gold! Thanks for the hard work

The laser and CNC videos are impressive, but this gets me excited to work on my own electronic test and measurement projects.

This looks like manual soldering hell to me. I mostly watch your videos for their production quality, dark humor and the awesome German accent (fellow German here). I'd even watch you moving grass if it is presented in your usual style

11:58 Deploying ground-to-ground missiles... Done!

Talking about low noise and having a Pulse Demon reference in the thumbnail? That seems contradictory! ;)

Fascinating and beautiful filmed thanks for sharing. Regards Chris

Man, your videos are making me want to get back to my metrology projects so bad. I must resist the urge.

About half a year ago, I got the ts80 (non p) and I am really impressed, how it handled soldering to large ground planes on a 4 in 1 esc. It's better than my cheep soldering station, that was almost the same price, but bought locally.

So the original Title was going to be "TS80 vs Ultralow Noise Tester: 9V Battery vs. 7805 vs. LTZ1000"

Really nice video Marco!

That's some pretty crazy soldering job dude!

This was very interesting! Really enjoyed watching. Please don’t apologise for the duration or rambling. Just do it as you like :)

Very interesting stuff. Love these types of videos.

I came here many months ago for the electronics content. However, you could be describing a tree growing for 30 minutes and I would watch that too. Thanks for bringing us excellent narration and overall production value.

Great content. I especially appreciate the super, super dry humor. Delivered with a straight face.

These videos are as (or more) interesting when compared to the CNC and laser stuff. I love this low noise series.

This is a great video! Please keep making them!

That discord notification really caught me of guard. Sounded so real.

seeing you open your JLCPCB package is making me wish more that mine was here already I know its been less than a week since it shipped but the suspense is killing me

Love the CNC Stuff, but this kind of content is my favorite, I will happily watch you chase PPMs all day long!

The CNC stuff is cool, but honestly, this is the content I am subscribed for. More, please!

Ahhh... new video to watch makes a great day. The capacitor hunting dogs at 11:57 made it perfect!

I love the humour you put into your videos :-). Einfach geil!

Loved the comment about the "absolute shielding fortress" comment. Even if this is a "low tech" project in the scope of the channel, I really enjoy these more accessible long form videos. Keep it up!

Nice haul out finding parts!

Loving the lower level content!

Really cool video! When I do the kind of electronics I do... I round to the nearest volt and hope for the best. If my oscilloscope cant measure it, its basically quantum foam.

I wish you had some summary/conclusions at the end :) This is getting more advanced than I can handle.

I really like your use of Grafana for long lab measurements. I need to check how to do it myself!!

This was not a boring video. Its great. Thank you . More like this 😀👍

Man, if you only knew how many times I have to hit pause! Learning a ton whilst laughing my ass off. Priceless.

this guy is the funniest guy on youtube. better than any comedian. and so knowledgeable aswell

Repson! Du bist wieder da :) Ich freu mich!

Realy nice work, thank you.

More of these style videos please.. CNC and Laser were fun, but this is where your story telling style shines.. Where else a concept like leakage current sounds so fun..

I've watched every one of this guys videos and I have no idea what he's talking about or doing 99% of the time. I think I just like his voice.

I was not ready for that "Noise" at the start.

Love this content!!!

I dont know what your video is about, but i like your vids annyways because i like the way youre telling us what youre doing and of courese youre humor :D

Thanks Marco, another great video. You have a LOT of new toys, the MDO (with Tek probes), the 2002 (!!!), the 5700A looks finished (looking forward to that video), the Advantest.... You've totally fallen down the voltnut rabbit hole, but what's even more worrying is you have a spectrum analyser and you mentioned a VNA in this video. I only hope you meant Volt Nuts Anonymous, otherwise it's only a matter of time before you go full "The Signal Path".

Long time no see boss. We missed your project please stay

Great Scott fantastic humor i love it. weiter so.

Very good video, as always.

Woah the multimeter trick is amazing.

Great vid!

GREAT HUMOUR!!! and you are not bad with electronics.

I watched this video when it was released, I had to search through some videos to see the bicycle dog release mechanism again 😄good stuff

Ah, yes UKposts Premium I don't have to pay for... I love these longer kind of videos althought I don't grasp everything you talk about but I would like it no other way. love your channel. truely Underrated for the content you provide.

I had absolutely no idea what he was doing, measuring or trying to achieve. But I watched anyways. I love the accent and the subtle humor. :)

I thought I was watching a 10 min video, until I was at 17 mins. Great to watch.

This low tech stuff is much easier to digest for a noob like me. Thank you!

This is amazing!

Inspiring me. Excellent!

These videos always tempt me to try to get back into electronics. But electronics requries money and brain cells, and I haven't got enough of either to spare.

To whoever is interested in changing the bandwidth to adjust this circuit for other types of measurements, that cascaded filter is actually called Multiple Feedback Low-pass Filter, not Sallen-Key Low-Pass Filter. Also note that the first stage has a very gentle roll-down starting at 6 Hz, while the second stage is set at 10 Hz with a little bump at this frequency. I suspect that Marco wanted to combine the gentle roll-down of the first stage with the bump on the second stage to provide more or less flat response over the whole frequency of interest? Nicely done :)

my opinion on how i feel about the more low tech videos: dude i dont know wtf is going on i can only read half of these things, i am a programmer but you are very interesting to listen to and i delude myself into thinking that i am learning some stuff

god your voice is so soothing, came for the TS80 soldering iron review, everything else speeds over my head at mach 9.6, certainly enough to lose many ppms heh

Your videos, and this hobby, makes me feel like a kid again. Out in the sandy back lot playin marbles for highhhh stakes. Thank You. :) (and I dig the humor)

I like these types of videos!

Honestly, I think one of those boards would be awesome for a synthesizer. Random LFOs tend to just be a sample and hold connected to a noise source; pair one of these babies with, say, a Chua circuit modulated by multiple noise sources, and you could get a truly random, continuous, smooth LFO.

I'm just a hobbyist Marco. You are light years ahead of me! But I get excited when you make a new video about your 8-digit toys/ I mean measuring devices & other cool items. You are the Frankenstein / Tesla of electronics! Ha, ha ha!👽 You rock! 👍📡

Thanks for KiCad plug-in refernce!! :)

This channel is underrated.
