I have a question. At 2:27 , If I were to measure from the resistor side of the switch to ground with multimeter set to measure DC volt, would I read 5 VDC? Second quesion. If the wire leading to the switch were somehow to get grounded, would the input show as on? I.E. same as if the the switch were closed?

One question so is the light flashing in DC?😅

So a car fuse would be DC, right..?

How to connect 2 pin into 1 pin using label ?

My favorite new feature is Arm Windows support. I can run it on my surface pro x.

I would like to know if the process is the same for the atmega 2560? If I can use the same components used in the video?

Do you have the video like this one but using Tektronic TDS model oscilloscope instead?

Thank you!

how did some one a hundred years ago figure out that the AC was actually flickering at 60X per second ??

Remember to check your shorts... 🩳

Is one current safer than the other? For example, running a refrigerator in a or Air Conditioner in a shed that is hooked up to a power bank or generator.

Great scope. But I thought this is more of a hobbyist channel. I do not think people who buy these kind of scopes watch this channel. So why bother making this video. Make one of a 12 bit Rigol or Siglent instead.

bellissimo video complimenti, spero ne farai molti altri sull'uso dell'oscilloscopio .

Sounds like a great piece of test equipment for the bench, but it’s sad that you have to still pay extra to get the proper Nixie tube display integrated :D. Thanks for an interesting and useful video.

HIGH! VOLTAGE! Rock n Roll!

keep switching regulators away from analog components

this was a good video. But the key thing, to me, is that you said R&S will release a firmware update to allow 4 FFTS on the MXO4. The MXO4 might be in my job's budget. & Ill poke around a bit & see if this firmware update applies to the MXO3 for example. EDIT: I just assumed the mxo3 exists, it doesnt. I dont see one on their site

words on this video's thumbnail persuade me that this is the most appropriate place to say that there are three grades of thermoelectric elements: pelty, Peltier, The Peltiest. I'm done

I think your rummors are correct about the Zone button. I have heard others that will add the 4xFFT to the MXO4 also, very soon ;)

Oh hell I haven't seen that teardown ! I felt your pain ! This is great 'eye candy' but out of my league....cheers!

Some of the high end oscilloscope manufacturers can display the waveform update rate on the screen (usually hidden by default), and some even report blind time as a percentage. Every digital oscilloscope manufacturer has fairly fast update rates in their nominal state (one channel, simple edge trigger, no math or advanced processing). But as soon as you add on a serial pattern trigger that gets executed as an offline trigger/search in software rather than running in hardware in real time with the acquisition system, the update rate drops several orders of magnitude. It would be awesome if the scope could draw the user's attention to this (highlight the lower waveform update rate and higher blind time), and also tell you why the measurement is slow and how to avoid the slowdown. For example, with an interleaved ADC, you may experience a slowdown when measuring channel 1 and 2 simultaneously. But if you move your probe from channel 2 to channel 3, which is connected to a different ADC, the measurement can run at twice the speed, sample rate, bandwidth, or waveform update rate. Oscilloscope manufacturers don't generally publish their high level block diagram architectures in the firmware, context help, user manual, or datasheets, and even if they did, most electrical engineers don't spend enough time with any one scope to demystify implementation details. Having the scope tell you "I can only run 2 hardware-accelerated math channels on channels 1-4; disable the extra math channels or move some of your probes over to channels 5-8 to get another 2 hardware-accelerated math channels. Or "Currently using SPI decode software trigger. Consider using hardware accelerated version of this trigger for faster measurements. <Fix>"

So ... the display of MXO-4 has resisted to the shock?

What a beautifull scope ! BTW I'm crying at the 27k€ price !

Why is so much of electronics just picking random value components?

am adicted to this channal.

nice vids

Great informative Video many thanks... just subscribed.. 🥳🥳🥳

FQP30N06L is obsolete? What's a good substitute?

what is the difference between a voltage regulator and a zener diode?

Since you mentioned the 78xx and 79xx rectifiers around 2:25:00 I wonder if you know the answer to this... power supplies found in some of the macs have a C78N05 used for regulating -5V output from the supply. But this part isn't well known today. Two supplies I've seen these in are the TDK 699-0153 (looks like Apple PN) and the Astec AA16251 (both are also very similar to the GS supply except -12V is not an output so GS supply can be used in their place). Trying to find a replacement for the regulator but am not sure what would be correct. Is 78N05 a negative input/output like you said is true of the 79series? I believe I probed a working supply (been a while so maybe not) IIRC I found -6V on pin2 and -5 on pin3 and p1 tied to ground. -6.3V seems a tad low for -5 out but whatever. This would also not follow the 78xx/79xx naming convention. Any idea what the N in the middle 78N05 indiecates? I know the trick to have positive regulator output negative voltage by moving ground, but the boards don't appear wired in that way.

Very cool! Been struggling with most of these issues, while trying to design my 2nd PCB/1st 4 layer PCB. 72 year old U of YT student. 🙄 Thanks to the KiCad developers for their efforts to make makers' lives easier. 👍

That this video gets right to the point (except for the moss joke) & has only 62k thins up out of 3.7M view's says a lot about the "average" YT watcher, so lazy they won't hit a like button to save their soul.

Hi there, hello! :-) Just wanted to say I appreciate the edited subtitles!

how does a fan turn in a single direction on a ac current?

Dreamy. Need to win in lotto today.

Why are you using the symbol for the ATmega168A-AU in your schematic instead of the ATmega328A-AU? Thanks

I feel personally attacked in that last part. 😡 I was just typing in the comments "when is v9 out" when that part played.... 😥

Why is it bad for the supply to short the ground? Is it because it damages the ground? If this were the case?

Still the best explainer video of ac and dc to this day.

Fillet line command was already available in KiCad7

This is really cool. I’ve always used an LcR or VNA to take capacitor measurements. Interested in this talk :)

I knew it! Engineers and bald guys can not be trust!

Almost like there is a reason to wear safety glasses

Hakko solder sucker, expensive but worth it.

Thanks to everyone who played along on April 1st. Although satire, everything in the video is true!
