Ask Dave LIVE
And I am live so says Xsplit and there's probably no one viewing me yet. Let's have a look. So I'm talking to myself impromptu I Know there we go Us: Dave Live there we go. I'm up.
No, there's five thumbs up already. Good. Like five seconds. There's five thumbs up.
Wow Do people like it'll load it on there. You don't have time to open your email and click on your thing. Or people have phones these days. they get the push notifications on the phones.
Oh geez, people are chatting like crazy already. This is nuts. Hang on. Hang on.
Top Chat No I Want Live chat? I Want all of them welcome to Live Chat? Remember to guard your privacy. Okay, hang on. let me let me pop it out. Come on.
Where's the pop out thing? Pop out? Check. Yeah, we go. So I'll bring it over here. Please excuse me.
please excuse the housekeeping. All right and I'll go. Webcam Ewwww. There you go.
Hmmm I don't know. Do I want like which one should be on top? Oh hang on. hey, what happened on my camera? Oh my what? What? My camera just died hello McFly sorry I don't know what happened and none. Hang on I My camera's died ed source my way from Montreal Mmm.
Source Devices: Screen capture means stream, no devices video, even media capture. There we go. I'm back. It's not.
You don't delete the other one. I Yes, mm-hmm that's really. Let's see if it does it again. If I really up? Yep.
if I try and reorder it doesn't like it I Reckon that's a bug in xsplit I reckon there's a bug in Xsplit there? Hmm yeah yeah. oh hang on I can use my upper D ah there you go. use a pity doodad arrow I reckon that's a bug. yeah that's a bug.
So if I go desktop up a Dee Doo Dah vanishes sorry I'm not like I can show you I can do the inception thing and Wow I reckon there's a bug in Xsplit sorry yeah this I write this bug in Xsplit where if I have this live chat window here I presume it's live chat window and that's not anything else. How do you like Doc? how do you like docker thing directly to the side to like fill up half the screen. Someone will know anyway. yep sorry that's yeah.
like I want to put this behind the other window but I can't do it because if I do it, it vanishes. It's dumb. totally dumb Wow Yeah yeah yeah, million people will be saying use Oppo BS Alright so I guess the solution to that is to simply turn the camera like that and go like that Larrick and that's the solution. Alright hi everyone, give me a high five five seconds.
Did I do it within 5 seconds? I guess I better do the tweeter ease to let the because this didn't announce on Twitter I did it and I think it announced on Twitter that I'm live I guess I'll do Facebook don't really use Facebook but I have a page on there and it Auto feeds my videos under Facebook and they're like people comment and everything. sorry I literally do not read comments on Facebook on my Facebook page on the eevblog Facebook page. Come and ask me anything. Publish Bingo! All right I'm up. Sorry Oh it's lots of hands. Just lots of hands who tuned. Remember me like a goldfish. I Forget what I Asked: Why am I? Why am I awake at 1:30 a.m.
sunlight coming through this. we can see inside of my head that's sunlight. It is. What is it.
He's bloody newfangled analog watches. 12:30 is 12 stupid camera focus your bastard like hand focus. hello McFly Thank you. There you go.
There you go. It's 12:30 Yes, that's a Bulova Accutron - I Know it's a ripoff Accutron It's not the real work. atrocious. It doesn't have the tuning fork.
I Know it's like the look of it. Hmm, you really miss fundamentals Friday It's not a question. It's not a question. it's a statement.
me an answer questions my girls were in DC coupling mode I Have no idea what you're referring to what I supported you, what has a Trump thing and the longer we leave it, the more it will devolve into something to do with Trump or something to do with Hitler Godwin's law I Don't want your hot dogs Wyatt I'm not gonna high-five you You want to do an RF probe PCB design All right no, what do you mean RF probe no no I guess is the answer to that. The flatter thing is this funny I tweeted this the other day I was watching I was watching Netflix and this like flat earth video popped up like they netflix actually paid for this right? and I thought I own like I tweeted like this is the dumbest thing ever but I was bored so I started a light flick through what to see how funny this would be you know and I was actually quite well produced. It was about this guy who's like the the God of flat earthers and Mark Sargent I think his name is and anyway it was. it was.
It's actually a pretty good documentary I'm like full of these flat earthers around as they were holding like this the world's first Flat Earth conference or whatever and at the end like they figured out that they would test it. you know because they they really want to be able to test this thing. So they got laser and they tried to put it night. yeah the first test they had failed.
you know cuz you over a slide over a couple hundred meters or whatever you gets, you know the slight curvature of the earth I don't know how they didn't account for just general undulations in the earth or whatever I'm not sure but anyway, maybe they got maybe you're sitting on a body of water or something and then you can still body of water. That'd do it. And they shined this laser. They had a first attempt, it failed but then they figured that they would.
They would hold up a lamp right so there. So the fail laser thing failed. they didn't get good results from it so they thought AHA let's just put holes in these two boards right? Or was it three boards can? I remember Anyway, like separated by like hundreds of meters and will shine a light. You know someone will be holding up a light at one end and if we can see the light through the holes, we can prove the earth is flat right. And they did the calculations and they figured that it would be like seven feet or something like that. but if the earth was curved because of the curvature of the earth it they would have to hold the light up to like I don't know, 15 feet or something right? So this is right. Spoiler Alert Spoiler Alert You can guess the result and they and this is right at the end of the movie. This is how the movie ends or the dokgo ends and you know and they go it right.
If it's a seven feet, we've proven that the earth is flat and scientific. no doubt, you know, done and and they. they do the test and they go. you know, they're holed up at seven feet or whatever and the light and they go.
we can't. The walkie-talkies we can't see it, we can't see it, hold it up a bit higher and sure enough they get up to 15 feet. We can see it. And the flat earth guy goes well.
that's interesting and then the movie ends. It's like yeah, the earth is round. It's hilarious I it's it's great anyway. sorry I haven't been watching the comments I just wanted to mmm I got a great chuckle out of that it was brought I thought it was a very well done documentary actually and it was funny.
It was funny. didn't watch all of us. kind of let's skip through bits. but it was.
It was pretty funny I sound like I have a couple of dicks in my mouth. What? Yeah, my voice sucks. Sue me. I didn't get back from the only got back from the gym not long ago where I almost killed myself.
So I'm like anyway, can I use a oscilloscope probe? An oscilloscope probe on my 4100 Heathkit Frequency count A 300 megahertz count of 10 megahertz. A hundred megahertz probe. Okay, yes, you can use your oscilloscope probe. certainly.
Is it a one-to-one or a tender one that 10 to one might not be valid if you don't have a 1 Meg input impedance for example. So anyway, yes, yes you can. Ah, favorite line in the Back to the Future series. Oh I don't know.
Let's just call it Great Scott because it's so generic. Video on best settings for FFT yeah maybe that'd be kind of. There's lots of variables though. hi man as sorry the the things are going so fast Dave Review the decent clone sold in station FX The-- it's born in a condo I Just got like an email from Banggood the other day and like normally only no it wasn't from Bang Good think but it was bang good.
Have this new. They're designing their own stuff now apparently and they have like this clone soldiering on. They wanted to know if I wanted to review it. It's like not really.
You know it's like cuz I don't like being good for a start and I don't want to support them I said in here and it looks pretty ordinary. It's just like no hmm. you know if you're gonna buy a solder and just go and buy that FX You know if you want to buy 20 bucks solder and I and just get the FX 9, 3, 6 ripoff, you know I've done a video on that and it's like it's less than 20 bucks even. Australian it's like 18 Australian dollars or something. It works, you know. takes the hakko irons and you know the clone ones takes the hakko tips. You can use the genuine tip side. yeah, whatever, how's the weather buy you today? it's all.
it's cloudy. It was kind of almost looking like it would rain before a lot of famous bloggers start to create and make their own products. Will you do something like that? makes something, makes them measuring stuff, etc. I Guess you've missed the whole 121 multimeter and the microcurrent, you know? And I rebadged some stuff, you know and we're working on the micro supply.
micro supply is happening. just ordering the new PCB for that. Tried to do it last night, but for some reason the Jlc PCB thing didn't load in the full layer out Iam files properly. Something's something they didn't You probably something went wrong.
So I'm not sure what the do. I Travel overseas to buy specific components? No. I want to travel overseas to buy components. Just order them right? Am I still building the Raspberry Pi Cluster supercomputer.
I'm always thinking about it. The problem is, it's like like like the Raspberry Pi is like yeah, like from a video blogging point of view, right? The thing that's going to get the views is it's because it's a Raspberry Pi right? But the Raspberry Pi sucks in terms of value for money, bang per buck. all that sort of stuff you know, like an orange pie for one quarter than one-fifth the price of something beats at hands-down and you know. And I don't want to fake title it I don't want to say Raspberry Pi supercomputer and then put orange pies or some other thing in it, you know? and I don't know and I'm high like and really all it is.
it like it's nothing. it's just basically sticking a bunch of raspberry pies together and hooking them up to a network cluster. You know I could do that in like an hour, right? It was. sorry.
hook it up Network cluster woman took a route er right hooking them up to a router and it's like, you know, whoopty-doo I did a video once on the you know how maybe I could make my own router on the board and stuff like that I don't know, it's like, ya know I'd really yeah, like yeah and I want to do it I want to do it, but it's just there's just so many little nitpicky things Eva it's like ah, that's just too simple and it's not really worth doing. and yeah, I don't know I I'm still thinking about it and yeah, it's occasionally. I give it some thought and if I can go in this direction or that, hmm how's the giveaway? go in. it went gangbusters like ten thousand comments or something.
I should just shut it off shortly. I don't know when it will pop up. no. The winner I'll stop.
thank you Maxim I don't know, it's like sorry I can't 48 rubles how the battery is doing at night? Let me go have a look I don't Yeah, they're not gonna leak I can tell he spoiler alert surprise surprise no leakage. It's like it could take months or not at all. Um so I am like yeah I don't know. Hey Def Pom got any more things to fix? Yeah I've got a half I've got a half open tech for 8 to 475. Hmm I shot some footage on that I think I've gotten on my thing somewhere. Your thoughts about the suspended solos campaign well serves them right. Serves I'm right. You don't post claims with demonstrable claims like that.
you're gonna get busted. It serves them right if they simply advertise it as a nice sexy I am paddle heater which you can buy on Aliexpress Like there's a lot of companies selling the exact same IR heater as this thing. glass panels and all right funky glass panels. So yeah, I yeah says I'm right.
It's good that they stopped it because the claims are and I have nothing wrong with the campaign. The campaign was fine. It's when you start making claims about being able to produce more energy than any other electric heater the you know the world's most efficient. It's the reason that the UK government shut down another Graphene Kickstarter It wasn't a Kickstarter but another graphene startup heater company.
Further, exactly the same thing. the exactly the same products. They made exactly the same. You know claims of it's more, you know, more efficient and everything and they shut them down as they should.
pee deep, will be dead. No, it won't Mm-hmm Compared to 15 years ago, how do you think that electronics learning will be compared to 15 years ago? Not quite. Thank you for the super chat by the way. Oh As a ten-dollar super check coming up, sorry ah sorry.
I'm pausing these comments because I Want to read them Yappy Dip: No, but it's never going to die. There's always uses for these. There's always single side of boards. You know what you can do.
single sided through-hole you can do single sided surface mount. You know, even your top in consumer products these days. Go look at the power supply inside. any modern you know, ten thousand dollar TV and you'll find a single sided PCB in there for the power supply because it's still cheaper.
But ironically, dip chips cost more to manufacture. In theory, they cost more to manufacture than a surface mount one. There's more material, The lead frame that they packaged it in is bigger, there's more material, there's more metal. Everything like it costs more.
Any theory, it should probably cost more to assemble to because a human and well know you can get automatic dip insertion machines and stuff. But anyway, yeah, it's just the surface mount is more is higher volume you know is always going to be ultimately cheaper. but as always in electronics, it depends Mike Thank you very much Mike sorry I got I got it wrong? Yes Mike I'd say I don't understand like that That means nothing to me I'm sorry hmm Duracell will destroy Dave ha Have a go you mug. Indoor solar harvesting is bogus. That's not bogus. You can do it. You can get out ex microwatts out of it, you know? No And the Solar Harvest is not Mike My calculator. Solar It works.
You know you can get used usable energy out of it, but it's not much. So you know as always with these things, there's a kernel of truth and then you know, 90% marketing. when am I gonna rip Solar roadways another one. Are they do anything dumb again? I don't know.
there's a lot of people keep sending me solar roadways links in different countries and they're doing this project and that? I don't know. maybe mm-hmm Well where was the sorry anything? Anything good in the dumpster today? No had looked nothing there. sorry. where's the $40 they $10 super chat Thank You Christopher Bork with Annie I'm building an environmental control system and haven't found Bulkhead Four five Volt fan that can seal unpowered looking to use dryer vent with flat plus servo or 3d printed iris diaphragm.
Thoughts on mechanism: Not quite sure you mean you're talking about bulkhead, so you're talking about penetration from one side to another. That's what bulkhead means. It means you have a bulkhead like on it. You know, usually I Think the terminology comes from a ship, right? And you want to penetrate from one side to the other.
You want to get signals or or pipes or anything across from one side to the other, but you don't want it to leak. That's the whole idea of a bulkhead that go for five volt fan that can seal unpowered I'm not sure what unpowered I can seal unpowered I'm not sure what that means. Looking to use dryer vent flapless servo Freddie Printed Iris diaphragm I'm not sure like it totally depends on what what sort of bulkhead you're talking about. If you just want a penetrator to go from one side to the other, that's not hard.
you can buy penetrators and then you can seal them with various things and what. Know what sort of environmental thing is that water is? it? Is it air? Is it? You know, some sort of gas? Not sure. More and more information required. Sorry Christopher but a dry event with a flap.
he's not a very good seal plus a servo or 3d. So you want to have like a servo that opens a flap on a bulkhead or a 3d printed iris diaphragm? that would be. you know, like that'd be cool. Maybe he's just like take apart lens or something and get that get the nice little light 7-blade iris out of it.
That'll be cool just because I think they look cool. Yep. Molly I'm doing great some Becca still day just read the comments. They even mentioned some respected youtuber yeah I Just realized now that I just was looking through the spam folder for the Solace video and it turns out that Maxim his name is or whatever the the guy that runs it he had posted well he's just copy and pasted from the comments over there he had posted in there but the YouTube determined it was spam. so I just um approved his comments. So his comments are now showing up so hope he doesn't get the impression that I was deleting comments or you know stuff like that, it's just $5 all the time is going down on the $5 one. I've got to read the $5 one hour man that just skipped it just and just jumped. Love your videos Dave Keep up the good work Thank you NAND or Szanto Santo with Solon said we landed on the moon is bogus all in up upper caps.
Yeah right. Hey Dave Thoughts on the 65 Co2 have been building a computer with one recently. Good funds Sherwood Nice to have a scope to help debug it until the contest along with 10,000 other people. I Haven't looked at how many video entries so far for that, but there are a lot of video.
I Was surprised by the number of video entries I haven't watched any of them yet I'll go through and watch them all when it's done, but they were like within like hours they were like 20 videos there or something. Well, I Always see a lot of resistors and capacitors on digital circuits. Apart from filtering, what do they do? Well, where do you see them? You know more Infirmary and more information required Shay They just could be. Well, you, you know? yeah.
Like you generally on digital circuits, you don't want resistors and capacitors. You might have Oh at some point, right? I'm thinking like RC circuit right? A resistor and a capacitor in like a like a low-pass filter kind of thing which you can do on our PWM signals of course. But resistors? You're probably talking about pull-up resistors and you're probably talking about bypass capacitors. And I've done videos on bypass capacitors? Don't think I've done a video on pull-up resistors, but go look at any like open Collector.
Any video on open using open collectors. I squared C bus all that sort of stuff. They need pull-up resistors because they don't work because they've got a transistor down the bottom and if you turn on a if you turn on the transistor, it pulls it down the ground. If you turn it off, then there's nothing.
It just floats. It's just a floating signal. You don't want to float in signal because then just noise gets introduced and it just goes all over the place. And that's why you need a pull-up resistor and it's always a trade off.
I Remember a job interview once it was a I went for a job interview and I think it was a one of those contract design houses you know, something like that and and one of the questions was can you use a 1 Meg pull-up resistor and of I went yeah, maybe it depends on the context. Later and and he said Oh what I'd like out of 4000 series CMOS or a 74 HC or whatever you know I can use in 1 Meg pull-up resistor I said yeah likely you know it's okay. mm-hmm get away with it and say can you may use 10 Meg and I said maybe and I knew where he was going I could have answered it from day one but liked it from the first question I knew I could have just simply kept talking but I wanted to sort of extract it out of him and can you use a hundred Meg maybe I just lost rolling the guy really and and he eventually said you know why, please explain and I eventually explained well it's the input bias current and if you have a certain you know the input, there's a certain input bias current even with you know the best CMOS stuff and you'll eventually get a voltage drop which will pull up below Vo H Vo Hi for example and once you do that all bets are off. and anyway yeah, miss some paid content. Oh it yeah I never mentioned the 6502 Co2 I got distracted. they miss other paid content. No 6502? Yeah. I've got it.
Have I got a 6502 board here. it's it's a kid I got in the mail bag I think it's a 6502 based like single-chip computable. I want to build that? So hmm yeah, 65 Co2 is cool. venerable chip back in the day.
software-defined radio stuff. Yeah well. I've got this I've got the focus you bastard. I actually I had the like I can get it running now.
hang on. hang on. hang on. hold on to your hat.
Video downloads so many different versions. It was a to get working spectrum spectrum spectrum. here it is. yeah, we can get it working right now right now.
Generic device Boom and there we go. There we go. That's how I'm at what is it the RTL 2832 you with the that's the base I'm going from what is it one Meg to 500 Meg I think and it it says I'm here 25 Meg to 1.7 gig receiver but I believe it's actually more than that I believe that. Come on focus you bastard.
Anyway I believe it's I'm and it's got like a TC XO pretty schmicker 1.5 ppm. It's pretty good. so which is a temperature compensated crystal oscillator and it says 25 gig to 1.7 25 me to 1.7 gig. but I believe it can go lower so I'm not sure why it says that I got this one because it had the much more usable SMA connector on it and and there you go we can do our frequency sweep.
So I was going to plug my EMC probe into that and you know, see if we can do much. It's only got like a 2 Meg band width or something or a 1 Meg bandwidth. Then you have to sweep across of course and you get all little artifacts and all sorts of crap. But yeah, it's usable as a spectrum analyzer.
so that one's sweeping across, you know it's It's reasonably good. It's kind of fast enough ish sweep to be able to like move around the board and and find stuff. maybe cheaply. but you know, if you're serious about it electronics and you're looking at EMC you're gonna have a scope with FFT anyway so you know it's it's probably better just to use that rather than one of these things.
But anyway, here there you go. I'll leave that leave that light running in the background because that kind of looks cool I'll leave that just running up there you go. Maybe I can plug like an antenna into order or something here. so Dave click on Christopher Why is Christopher there he is? there's Mike there it is, put the helmet on isn't clipped up dude, that's a no H&S risk and somebody has a decent view that's spoiled in the background by all those all those buildings in the background there. Love your videos. Keep up. Go off. Jeez, that's an arty photo.
Love the beard. and Matthew has a cat with some cherry things Mike Unleash one thank you Ozzy Five Ozzy its Mike and Ozzy I assume I as AUD I'm having trouble building RAM for my Minecraft computer Can please help server sorry band English Sorry I know absolutely nothing about Minecraft and building RAM for my your Minecraft computer Why do you build Ram You just buy RAM and plug it in I don't know what Minecraft I don't know anything about Minecraft I'm sorry, yeah, no I really don't Hmm, well cool huh? Hang on. he had another one. Oh well.
hang on. Why no, geez, hang on I have a three phases. sorry for anyone asking questions in between I mean like like it looks like I'm staring at the screen, but I'm really just like staring into the void half the time. I'm occasionally answering questions in there.
but the soupy I got adds to the super chat ones. I Have a three phase digital Cape Cod CNC There you go. That's like a press That's like a it's just two prints ylides out on these I Can't point to it on the screen I Can't move my cursor because it'll go outside. slides in and out.
It goes up and down and it's a it's a Priora No, that's a drill that's a shock. Is it on the top? I Have a three phase digital converter these putting noise on to the mains. three-phase digital. Any ideas for filtering it around? I Just did a video using a power quality meter.
That's not hugely my area, but that's it's you're basically talking about conducted mode noise there. So really, it's like a big-ass chokes. That's how you get around that if you look at the Schaffner for example, the teardown of the Schaffner impulse unit that I did recently look at the big common mode choke that they had to put on that thing. It was enormous.
and then they had to have this custom extra custom filter as well. After that, just to stop all the crap, those impulses get him back out. That's how serious you know they are there enormous things. You know, you can buy a little common mode chokes, but they're generally not going to do the business.
You really need to put massive common mode chokes on there and then you conducted. then. that doesn't necessarily stop your conducted mode interference if you're talking about EMC as well. So there's a huge see.
it is rare I see it is round right I Just did a video. Yeah, it's It's quite a complex subject. Something I can't really answer he. you know in any without knowing without looking at the item, looking at the context and stuff. and what's a free phase digital converter. And once again, three-phase is is something that I've never really dealt with either because all all the stuff I've ever worked on a single phase and then I'm not really into working on main stuff anyway. So do you know Mr. Carson's lab channels? Yes, What do you think about this guy? I don't know I'm not subscribed I No no I'm no.
I'm subscribed. but I don't get notifications I'd I've rarely watched one of his videos. only if they happen to pop up and only if it seems of relevance and of interest to me does a reasonable job. There was a lot of controversy about an ear so it was an ESR tester he did or something.
it was an insulation tester or something. It was a big thing about on the forum about how he was like claiming stuff that wasn't possible or something like that. I don't know. Looking forward to the New South Wales election in a couple of weeks.
Is there an election? Who cares? You know? Yes. Why we don't have independence in our electorate anyway. Can't even vote for a bloody independent cuz there are none. I'm thinking about running myself just so I can vote for myself quad-core memory I Read all comments No I read thousands of comments a day Shay I answered your question way back Shay you're asking again Second suck of the South It's four pages, twenty five post per page contest videos to our right Wow Okay, hundred videos.
Wow. I Hope they're all short. there's any five-minute ones. I'm just not gonna watch him.
You'll be out. She didn't follow my instructions. don't an Internet talked about making PCBs for near-field probes Am I going to I Might. but it's like it's so simple.
It's literally a four layer board with two traces and a ground plane on it. You know? no, but we know we rather do something more interesting. And David two and I have talked about having aid a scanner. I mean like maybe retrofit in an XY scanner bed? or maybe a document scanner or something like that retrofitting it with like, maybe you know, 50 tiny little coils and they're multiplexing them.
And you know, little near-field probes and they're multiplexing them and stuff like that. And yeah, that might be a project, but it's so many projects to work on. No, the video tore through my lab would not be interesting because the problem is Vova. My lab is not really a working lab.
It is A because I don't do engineering as a living anymore. It's not a working lab. It's more setup in total chaos for just making videos. Nothing like a you know nothing set up properly.
Nothing's organized properly. It's it's just there's nothing to see. Do you know labs that are interesting are working labs to see how people productively do things during the day and my one set up from making videos it's not set up for you know, as a lab to do work in. you know, engineering work it all day, every day. Very two very different requirements. Do we know? First-year engineering project about curling split times I Have no idea what that is Yes. I Like dogs I I Had two dogs growing up. The wife won't let me have a dog she reckons I can't even take care of myself, let alone a dog.
And she's right. Doo doo avionics, tear downs. Why don't I do more people don't send me avionics gear. Now there's some good resources for learning about Bjts.
I don't know, it's tons I'm sure tons of books don't go in. definitely have to get a good understanding I Really know there's lots of text books out there on BJT amplifiers. Any decent textbook will have all your standard. You know your your BJT characteristic curves and the whole.
you know it'll go through the whole the, the operating, the bias points, and the operating things and the whole works. It's tons of stuff out there. I Have no idea what an IRS 2092 is. It's an Infineon Technology high performance Class D Audio amp.
Who cares? It's a protected digital audio amplifier. May 16 people George Pell Got the Bastard IRS 2092 protected digital audio amplifier Anything special about floating inputs enable easily a half bridge implementation program y-direction I Overcome protection so free say from around the reset did time for improved THD Performances start and stop click noise reduction my nose immunity under Iranians Deliver 500 watts in now put power 500 watts in output I Was going to say not in a 16-pin dip, you're not and I looked out of there's the external power trainees Yeah, all right Whoopty-doo not sorry. That doesn't interest me in the least. So the answer to that would be no I'm not gonna do a video and I just a generic class to you can double us 2800 won I Have no idea it's an art a fruit thing, Know what? So they have just got the datasheet world semi whose world semi 3 channel constant current lead driver with programmable PWM outputs okay-y currents 5 250 milliamps do you mean for each channel? blah blah blah blah.
They're all into these flashy, flashy things. It's probably on one of their tape paste lend things or whatever. although this is a oh it's a claw concern SDI Ok, it's got a fee. Yeah, it's gotten sto so he can daisy-chain Um Ok so it's just a serial shift register.
It's just a clock line and it's got a clock out to clock in and clock out. That's interesting. sorry buffers it each time because that's one of the problems with having long clock lines and stuff like that is. You know the further it goes the greater the capacitance and the slew rate just goes to help and you the drive capability.
You know any given digital driver clock drivers only going to be able to drive X amount of capacitance and the longer you make the line more problems you have but if you feed the clock in and then you buffer it and clock it out, you're ready for the next leg. You know I meet a long legal or however long you want to send it. So yeah, it just rebuffed is that locally? So that's why they do that. Apart from that, I'm sure it's just a cereal. Yeah, well, it's a cereal shift registry and it probably has commands and stuff because you've got to set Pwms so there's probably yep. Here we go: Input Control PWM Controller being get reference. that'd be for your constant current stuff. and yeah, RF Be there you go.
There's your there's your constant current. so you've got to have an external shunt I'm assuming and and then that configuration just maintains you. Does your constant current Peter in compare a grayscale or data latches. Okay, yep.
so you can latch so you gots clock in, serial data in grey scale, data shift, register data, and clock. reconstruct the clock reconstruction. and yep, higher voltage application. Yeah, and there's your current sense Oh Anyway, compulsive Jana There's your current sense resistor as I said because it's constant current drive and that's the internal thing that we saw up there for the block diagram.
Yep, they got done. What is it? Three channels and sorry question was can be use for controlling motors through H bridges? Not really that's designed for constant current output. So I'd say ordinarily not. but I wouldn't say it's not possible.
but I mean it's a PWM signal generator. Can you just get the PWM Okay, you could just get the PWM out and not use it. No, you can't No, no because you can't get the direct PWM out, you can only do it as part of a constant current configuration I think pretty sure I'd be surprised if you could do it otherwise. So I'm gonna I'm gonna say please, Someone correct me in the comments.
but I'm gonna say no to that through H bridges purely because you can't get the PWM out out of. well. no, you could. No, of course you could.
you can. You can put resistors there and then resistors instead of LEDs and then you get the PWM out and as long as you don't feel to it, that Pwn can go into eventually in the H bridge. and yeah, you could do it. Yep.
I revised that no I bar my customs, a lab, the customs joh, no future video and RF amplifier classes, that's not my thing. Oh, it's not my thing. I'm sure it's a very fascinating career to work in. 1 kilo Hertz Um, Gallium nitride.
GA And that'd be gallium nitride wouldn't it? No pole stamps? I'm sure this is fascinating stuff. It's just not my area of interest nor expertise. So No you wouldn't expect a video from me on that Mm-hmm your Arduino it keeps getting stuck. Don't you hate when that happens? Stuck? What does that mean? Generally, they just work like it did the software thing.
your selfies getting stuck. Please say any way to debug that I don't know, there's not enough information. How could I possibly do that? God save the Commonwealth There is no God you've been duped. Greatest con of all time now which god it's been hundreds of hundreds, thank you very much. Tom Evans That's what I wanna hear Dear Dave Can you please do tutorial on how to build a ram into my craft computer? Thanks Mike Ain't it? What did you ask that again? Mike I'm sure I answered that before I'd like how to build ram into a Minecraft computer I Know nothing about Minecraft or what the requirements would be I Thought you can run Minecraft and pretty much anything, can't you? So I'll build on RAM into I Don't understand any computer runs Minecraft, doesn't it? I don't I I don't understand the question at all. sorry Mike or have I gone back my mom have I gone that far back? Oh god sorry Oh God So many of them Sorry. Okay next that look it's it's a dick and balls. Not a very good, not a very good dick and balls I've gotta say Pepe 6666 or quad six.
Um, that's a pretty bad dick and Balls that's pretty dodgy looking. Hmm. I've done a photo and I've done a video on Dick and Balls on my second channel. Any tips for catching photo? Potato, Potato you've asked a question before I think as in another show hi Dave Hope you were doing well.
Any tip on catching mistakes true in the design face, so don't waste money on PCBs just them, not just for them not to work. We talked about this on the Air Power recently and we linked to it's probably in the last three or four might know. Well, last couple that I've done anyway of the Amp hour, so you might want to look it out. There's a link I don't have it to hand, but there's a link to a document that has that attempts to be a universal checklist for catching mistakes during the design phase.
Exactly this thing. and the checklist is already like 10 pages long. And as I mentioned on the Amp hour, it could effectively be infinitely long. There is.
Yeah, there's some stuff that you do all the time, you know, like making sure that your Orion you know your ERC is correct, making sure all your nets are connected and everything, making sure your pack, double-checking your packages and your pin outs and you know so you don't get them swapped and start. You know, transistor pin outs think it's swapped. Yeah, really simple things like that, but ultimately there are hundreds and hundreds of different things specific to any design. You know if I Sat there and really thought about it, if you gave me a design and I really sat there and thought about it, I came sure.
I could come up with a list of a hundred different things that you could check for that one particular design. That could you know? Yeah, that could screw you up if you really came down to it. So unfortunately, they're having a universal list like this. Yeah, it's like, hey, it's gonna have. You know it. Maybe a dozen good things that are kind of generic, but beyond that, it's dusty. You're very specific just for them not to work. Yeah, it's like yeah, your big one is your big one is your DRC and your ERC The ERC is the electrical schematic.
So you check to make sure that all of you know you're not driving. especially if you set it up properly in your ear. say I'm sure I've done a video on this. Maybe as part of the the Nixie tube design series.
Perhaps where you if you do your symbols right in your schematic, you can specify them as outputs and/or inputs and stuff like that. And then your Er C should flag. there's a big matrix in Altium There is a you know, cross things that you can check and one of them might be an output driving. and output.
You've got two outputs connected together. accidentally connect together. On the schematic, it'll flag that for example. and yeah, so that's you know that's the first step.
and then DRC on your PCB And then as I said, they're your packages and pin outs and and and and it goes down the rabbit hole. It's endless. So sorry, it's not that easy. I'm afraid.
Why do I think of this little cig gin with no link? Well, Hi Dave Is there any possibility? OPA 2156 works better than OPA in a nest in a nested feedback composite amplify with cheese that's specific. Can there be a more spot anything? I've had such a specific question ever and MJ and work better than a 16-12 OPA Wow I'd have to look in the combinations. So so you're saying that these two are combined and and Njm is that new? Japan Corp So the new Japan Corp won I'd have to look up every single one of those. so I'd have to open all four chips I'd have to try and figure out what your design thing is work better than OPA 1612 So you're talking about Jewel Low-noise Jewel Operational amplifier Yes, new new Japan Radios right? Hello McFly There we go.
It's a low-noise Jewel Operational amplifier, so you implied that it was a combination of these. an ultra-low noise wideband with Precision Rio Douro amplifier 36 volt job'. It's probably not going to be cheap. 25 made gain-bandwidth product, high supply works from 4 and 1/2 to 36 volts.
So you it's all about you're employing that Their combined work better than OPA in a nested feedback composite amplifier with at EPA What's At EPA Sounds like some sort of power amp or something - LEDs Stereo Headphone amplifier I wasn't far off Oh High-power for headphones? Maybe high fidelity stereo headphone amplifier, right? So like and and you have to go Works and you have to define once again, you have to define what works better. What does your spec? You know you're going for noise. You know I assume it's like noise THD noise. that sort of thing THD of 112 Point Five, you know, like you're just not going to hear this sort of stuff I would say it doesn't matter I would say I would say that either of those is not going to. It's not going to matter without even looking at these other ones. I'd say it's not going to matter because you're 99% of the problem is going to come from which headphones you use for example. so you can gild the lily on your high fidelity stereo headphone amplifier. but ultimately end of the day you know it comes down to like are you using like these little you know ear buddy things like what's the point designing your super high fidelity amplify even if you get one of these that cost cost a couple hundred bucks or even if you've got you know, a half decent pair of monitor headphones.
Okay, you know these are better, but it's still at the end of the day I Don't think it's going to matter a huge amount I'd be stunned if you you know if you did a true a be listening test I'd be stunned if you could hear the difference between either of those two solutions you're talking about and so yeah I'd I I think you're gilding the lily fanned, you could be gilding the lily there John for no reason, go for the cheaper solution I'd say and if people can't hear the difference, what does it matter? Unless you want to be and you know spec Manship and you want to talk about marketing, What low cost scope would you buy if you were beginning? look I get either the ROI goal or the Sigler like the Right Goal 1054 Zed or the Siglent 1202, xee, or 1204 get the four channel one. Don't buy a tube to channel and get a four channel scope if I was if I was beginning and once again, how much money have you got to spend? What's low cost? Hmm. all of these questions. They always depend upon the circumstances.
Salty Dave again tonight. Why am I Salty? Is it to deal with the Aussie Aussie Aussie Boy boy Dean Johnson Thank you very much doing. what's that I said a patch oh it's piss small. Can't even read that.
No idea what that is. it's playing some sort of defense. There's a chopper in there, some sort of Defense badge. Mmm.
nice to work in the defense industry. Yeah, like you just get one of those too. Seriously like whichever like I whichever country you're from as you're donating the Yankee bucks. So I assume you from Yankee land whichever one you can get cheapest out of those signaling or the rygar.
Really, there's not much else competition unless you want to put something specific unless you have some sort of specific requirement. But if you're just beginning just lost cost, scoping Gap. even like they're real cheapest, ask nastiest piece of crap. 100 on on eBay is going to do the business.
Don't buy a USB you won't get a bench scope. they're just nicer. but even the cheapest crappiest tech way one or something. I've done a video on that? you know.
Kinda like it works like, you know, if it. If it saves a hundred bucks and you can spend a hundred bucks on another couple of multimeters and a power supply or something like that, then yeah, you're better off doing that. Mm-hmm Can I do some project series just like the micro supply? I learned a ton. Yeah, maybe I don't know. The problem with that is mentioned many times is you get so many comments I still get emails I still get emails and comments all the time about this. You know, five-year-old more. How long ago did I do the micro supply series? You know in 20 parts because I had to design that I've having two designs running at the same time and it still good email. So why did you do this? Why didn't you do this? It's like huh? Yep, what areas do you think the big innovations and new technologies will come in the future? What ever a robotic general AI help us come reality or will there always be considered dangerous are the whole AI thing is we're not even close.
We are not even remotely close to having anything like AI that like yeah, there's some niche stuff that works great, but they're like we're not even close to general AI Not closed. No. I'm close to worrying about that. They got up, you know.
Hmm. Take us on and you know the thing. I'm gonna start killing people and they're gonna have a consciousness and all that. sort of.
It's just silly. Consider doing like dangerous. It's just like if you're so dumb to build like some learning AI into a drone that has a gun on it, well you know, like it's just not even remotely close to anything that we can't control. It's just stupid.
Like sick of hearing about it. Sick of hearing about self-driving cars too. Don't get me started on self-driving cars Oh A couple of years away, you know. Okay, once again, no their Pasa.
Once again it comes down to like all the nuances in the real world. Okay, yes, self-driving cars. Yes, you can get them. and yes, technically they work.
but it the devil's in the huge infinite amount of detail. Man, it's just it's just. it's just unbelievable. I Guarantee you that a self-driving car could not come up to my building and pick me up I Guarantee you couldn't do it.
Couldn't do it because it's gone off the road, it's gone onto a private driveway. it's gone and you would have to map it for this specific location. you would have to look out and if it's a cab and auto. I could go on for hours.
Like if it's all made of cabinets looking for people that can't see that you're flagging it down. It doesn't know that you're waving like city. can't see people's intentions walking towards their car knowing that they're going to pull out. How do you find a parking spot? It's just it's just ridiculous.
We're not even remotely close. There's a million different, very, you know nuances and variations in all this sort of stuff. How fast! Amazed. Amazed there does my digital circuit have to be.
And I'll bet money on that too. A little bit money on that. How fast is my digital circuit have to be before length matching becomes important? Or how do I determine this? Generally, it is not. It's not necessarily about the speed, it's there well. but when you start using like, well. yeah it is. But basically if you using stuff that requires length matching, you'll know it. If you're doing.
you know Ddr3, memory and stuff like that and you will know it. It'll tell you in the app notes. Read the app, not you know you will. how do you determine it? Generally you read the app notes and they go well.
If they're example ones have length matching, then you know the little wiggly traces. you serpentine traces, they're called. They come down and you know length match and stuff like that. If you're doing multi-channel synchronized sampling and stuff like that, you have to.
you know you're designing an oscilloscope. You have to sample accurately across all four channels. Yeah, you got to match the length and stuff like that and it's There's no magic. You can't just say oh, it's over 200 megahertz and you have to have length matching.
It depends on your system what you're driving. all that sort of jazz. As always, it depends I Wish I had like an antenna for this thing. Maybe you just got one up like a little antenna II Haven't done this yet.
You just plug a little antenna thing into you and hello, that still. is that still sweeping? That's a sweeping anymore. My spectrum has stopped. it was sweeping a second ago.
I Swear. uh-huh Oh whoa whoa. I Don't think it's kind of reach I Don't think this reconnects. Oh yes it does though.
Hey, are we getting something? No. what's that? There we go. it's sweeping. Wow Let's just go from like oh, what's the that's the that's the FM radio band.
like nothing. disconnect the antenna. nothing Am I using this thing right? People are probably screaming at me. sorry I'm not looking at the real-time update comments.
Well well I think something's gone horribly wrong there. Maybe it's not. Maybe it's not connecting properly. There we go.
that looks better. All you guys just stopped it. just crashed. Oh yeah, no set scale.
Maybe my sick guy. it scales off autoscale. Hey there we go. That's that's nicer.
There we go. What a scale. Still not showing anything up. We kind of expected to o88 kilohertz What? I know 88,000 kilohertz, 88 megahertz? Yeah.
hmm fpza ziz. stupid Help Sofia get your grabber right to saying what happened to the crusty Ps3 I said oh, you already set the Ps3 embiez Frenchie um I still have it Um yeah. I was gonna do like a DA is gonna do like a BGA reflow thing and it still went I still have it. sorry about that.
Um hmm. tight and timer. Oh hang on. what happened is it? Is there a limited number of comments that it holds? I Think there might be a limited number of comments. Thank you Nemo timer I don't know what that means I Don't manage my component inventory or religion is garbage? Absolutely. Hey Dave Any interest in doing a video on a radiation hardened circuit design? Oh yeah, I've done. Am I done I done I done I done the video I Did a video with space radiation hard and thing and that was quite interesting. Circuit is I Yeah So technically I've already done a video search for Eevblog radiation hardened and you'll find it I Talked with God Carsten his name I think from the the moon lunar Xprize thing LD the Audi or Lunar Rover Are you me Haze onus is on the person making the claim.
Yes it is. So if you say God does not exist, you've got to convince me. good luck. Are you kidding? The claim is that you can't do that.
What universe are you living in Hayes Anderson Wow I Assume that's not a typo if you're saying God does not exist. No, you're the one. People are the ones making the claim that God their God and that they just happened to be born into. You know it's not like they're gonna research to all the hundreds of God's out there.
and God Oh yeah, I Think this one's true. No, it's just that they happened to be born into that one and that they happened to believe in it does not exist And you got to begin convince me like piss off. it's a Russell's teapot. could be Dave's multimeter.
Dave's multimeter is the new version of Russell's teapot. I Can guarantee you that there is I Believe deeply held belief that there is a multimeter orbiting Mars Prove me wrong. Dave's multimeter. it's Russell's teapot.
It's the 21st century Russell's teapot. Dear ID I Believe who is more famous Dave or Donald Trump Flavio This is interesting. Technically at one point it was me. Believe it or not.
Believe it or not if you. well this was about ideas before he came president. Okay, my Wikipedia page had more. There was like like two or three or four or people just debating endlessly.
If you go into their like, the comments or whatever, what's the Wikipedia comments thing, the revision. you know where with where they discuss making changes to the page and so people who make changes you can you know they argue. you can't make that because blah blah rule. you know, blah blah I'm changing it back because blah blah and my page.
My Wikipedia page number of comments had more than Donald Trump's arguments on Donald Trump's Wikipedia pages. Probably not true now because he's president, but it was a slower just you know, a year before he became president of the zone. I Don't know whether or not was before he ran but no knows could have been I don't know but if that's how you define famous then I was more famous than Donald Trump No more people arguing. Oh, there was more argument going on about my Wikipedia page than Donald Trump's true story, true story, it's archived on the floor somewhere. It's like it was hilarious. Why can't you make a video about different electrical motors? Are you a chicken Yeah right? Nobody calls me chicken like I don't give a about motors I have no interesting motors. therefore I don't make videos on them Dave Have you ever had any serious fan stalker moments? I'm not. No, no, not really.
I was serious. Oh yeah, yeah actually. yes I've had yeah. I've had to go to the police because yeah, somebody posted and and I know who it was posted porn child porn on my forum on Christmas Day and let's just say they're an ex, a pissed-off ex forum user and yeah, they were reported to the police I have there.
they gave me all the details and they were investigating it and yep, but not like this fan. I don't you know? I've had phone calls at home and stuff like that, but they're just excited fans. You wanted to track me down, you know? And and anyone who meets you on the street, anyone that stops me in the street and like they're they're the nicest people. I've never had anyone they either on the street or at an event you know I come up and and you know have a go at me or something.
It's just like people are really nice. It's great. It just just doesn't happen because people are gutless people. People don't have the guts to come up to your face and say your yeah, the RC 2014 that was it I've still got it here.
I'm gonna build it. Mmm What's my favorite food? I'm not big on food. a lot of foodie. I could eat the same thing every day and it wouldn't bother me, wouldn't bother me.
it's just calories, you know? Yeah. I like my chocolate? Yeah. I like my ice cream? Yeah, but you know, can you see clipping fairly clearly with a cheap oscilloscope? Yeah, any oscilloscopes going to show clipping? You seem tired. No, well you know.
I'm buggered from the gym and I'm out of water bag smelly gym clothes. Whoo! There's a lot of sweat in there sometimes. I Can lose up to two kilos of sweat in a class. Well that was an old gym I went to old gym I used to go to that was an air-conditioned I was a real man in gym that one and and it was Yeah yeah, that was yep 40 degree heat under the tin roof doing the cardio club class I just spilt lucky it's only water.
How do I keep fit? I Go to the gym, try to get away from the screen with your occasions occasions. Fun! It's not fun with our friends our yeah yeah, it's better I like I've done geocaching on my own, but yeah, it's more fun. How do I do it? I go to the gym and I do group fitness classes I do group classes cuz I don't like going to the gym and just working out on my own. It's boring I'm just gonna slack off and it's just boring I I Mostly do I mostly do group fitness classes and then you meet people and you know, especially in the cardio classes and stuff.
you know your team are all the boxing classes or ki Max or or whatever it is the CrossFit cross-trained actual classes like you meet, you know you group up and you know you pair up and stuff like that and you meet people all the time. It's great. Hmm yeah like I just like after the gym class today I Just stuck around for half an hour talking to this lady who's who had a knee reconstruction. So we're talking about Neri constructions and we're talking about we're talking about kids and we're talking about you know she's got our own supplement business and we're talking about all sorts of stuff. and yeah, half an hour forty minutes just chatting after the class. Anyway, if I don't start keeping up with his confidence, look at them all. I can't possibly how many people are watching. By the way, 565 560 that's not bad for now.
Announcement at all right? Thumbs down a thigh. People don't like it Hey Dave thank you very much Sean see SNM Hey Dave Do you have any advice for someone considering government? Lab? Government / lab versus industrial Electrical Design Work advice: I Don't know I've never worked in a government lab I almost did once I almost applied for a job at a Zeo it was in Canberra though didn't wanna move to Canberra but you know I thought like oh yeah we could not spy gear like as I loved I was into FM bugs at the time and other you know spy stuff and I thought I that it cool. You know that was working in the electronics design department at Azo which is a Zio's equivalent to the National Security Agency in the US for example. that's our equivalent hmm versus industry electrical design work I Don't know.
It depends what you're interested in. A government stuff can be bought any. Either one can be boring as batshit or can be exciting that it's It's purely potluck, really. And you're talking about electrical design work.
You're talking about electronics because there's a difference. I Don't eat I Generally you know it. Electrical to me means like power electrical. You know, transmission lines.
stuff like that. it means you know, big. like energy. big power stuff.
hmm I don't manage my component inventory. you've asked that twice. I don't piss poor at it. so yeah, sorry I don't really haven't I can't mmm.
snow ice my haven't smoked any reefers Great Barrier Reef are the first-person Great Barrier Reef are the first person to tell me what that's from wins the internet. No. I haven't count the number of couch feet. No one's got it yet.
It's gonna be a delay. There's like 30 second delay. No one's got a year. Great Barrier Reef Oh come on, someone has to get it.
Oh yeah. I Still use the pace. Got a bunch irons in there. it still use that.
It's alright. I Really like the alloy case and the fact that it's got the rails and you can possibly I might have to actually mount it under my bench permanently. Ostentatious. Graham No knobs.
Graham Mops Knobs wins the Internet Ostentatious. Australia Yep. Graham Nobles wins the Internet Oh look for those who don't know, look I'll make it easy for you Here we go. copy link address Here we go hey guy Australian I Don't think it is anymore. but at one time this was the highest selling album of all time. High selling single musical single of all time in Australia Ostentatious. And it wasn't a song, it was a stand-up comedy routine. So the highest selling song of all time in Australia was a stand-up comedy routine.
I'm not kidding and this is the this is the video clip for it. Ostentatious. Ostentatious is the one who performed. it was actually written by Billy Birmingham The Twelfth Man.
Trust me, you want to get Billy Bamboo Hems Twelfth A Man album if you're in. especially if he into cricket. You know if you're an Aussie you're a Pamir A you're in New Zealand and you'll know all about World Series Cricket and you'll know all about Billy Birmingham the 12th Man stray Aussie as right Ozzy as hi from Argentina dude OH The LCD yeah the LCD I don't know I don't know what happened in the I think it's still submitted? It's got to be sitting in a box somewhere. It didn't come out of the move.
It didn't survive the move. Well it survived. It's sitting. It's got to be sitting in a box somewhere.
The LCD I never powered it back up. What? No, it wasn't Men at Work Down Under. No no, it was not minute work. Down Under and Men at Work is actually the lead singer and Men at Work is not Australian Hmm.
So there you go. Would have assumed it was Kevin Bloody Wilson in the back of the Ute I am educating I'm educating the non Australians here or even the young and young Australians who won't know anything about what I'm talking to? There we go Kevin Bloody will pop up Kevin Bloody Wilson Rooting in the back of the Ute can. aluminium soda cans be used for a heatsink? Oh yeah, maybe but there. but no.
But the problem is they're going to be piss-poor because they're so thin that to get to ready to transfer the heat through the aluminium, it's just. it just doesn't have the thickness required. So it's actually going to be a very poor heatsink. That's why he thinks you see have a real thick base of them to transfer the heat from your device that you attach to that you know like it's a big baseplate and then the heat can flow through the big metal base in the big alloy baseplate and then up to the fins where it radiates off the surface.
Or it can convict off the surface, right? So yeah, an aluminium cam will be a poor heatsink. Very poor. There's just no bulk in it and there's no efficiency. It might a large surface area, but that doesn't mean jack.
If you can't actually get the heat, the thermal resistance is so high, get into the extreme outer edges of the heat it's gonna be useless. It's gonna be useless. Midnight Oil is awesome! I Went to see the oils last year. do I like R&D work or just design work. Ah, it's all the same. It's all the same. It's some of the coolest stuff I've done. spend like just R&D work though I guess yeah like I never really enjoyed contract design work like I did I worked as a contract designer and I like several times over my career and I just you know I just didn't really didn't enjoy it all that much.
so I'd say I'd prefer R&D work maybe cuz R&D work. You've got a big budget and you know usually quite flexible timelines and you just bum around working on cool stuff. Now I haven't reviewed nokey soldering iron? No. I've never had to deal with RSI I Was just talking to someone at the gym today about RSI and how they said yeah the yeah the girl said her daughter got.
you know I was talking to after the gym class. she said yeah, her daughter got RSI she's only like 25, 23 or something and and a daughter's got a hairy sigh from using the keyboards. I'm going, you know I'm surprised it hasn't happened to me, right? I've been using a keyboard for you know, 30-plus years or whatever and ya know I have not had our acai problems but I am like one of those people who like has good posture I'm always conscious of my posture and I'm always like doing little not really exercises. but I'm always like moving around, fidgeting and stuff like that so maybe maybe that has something to do with it I don't know.
Seems to me that Dave is somewhat sold out with the ear splitter eevblog somewhat sold out. What does that mean? it's they I did the it's not that statements not really phrased. Looks like Dave is somewhat sold out with you. Oh no no no I stand corrected.
Seems to me that Dave or has it should be has somewhat sold out. It's not is somewhat sold out, its has someone thought should be has you got a claim? I'm Psalms I've sold out. At least phrase your thing correctly. Kevin But you know it's okay.
How in what way have I sold out? In what way have I sold out? Please come on keV Come on keV Put up or shut up. Thank you Rasim button because everyone who makes these claims, everyone who's done it over the years demonstrable. II I can destroy them. It's just like I can destroy their arguments like come on keV have a sold out yeah I'm I'm I'm not a Fivefinger type or I'm like four fingers and a thumb basher I'm a thumb spacebar.
you know I'm like four fingers in a and a thumb I'm not I do
Hi Dave
Dave must see the Aussie series "Girls out West"! 😛😍
You're right about dating mate. And dating nowadays bloody well sucks especially being 50 years old and having seen before and after the world get small
Dave! A Yank here! Two questions, 1) Have you ever heard of the matrix technology MCR 5000 capacitor LCR meter? And two, have you ever seen the Australian (naughty$ series called "girls out west"? Lol!!!!
DAMMIT DAVE HOW TO BUILD RAM IN A MINECRAFT SERVER???
You should do more live shows.

This guy is AWESOME ! Very clever, very down to earth. No bullshit…whoops, this comment may be banned.
I like how you automatically assume someone who receives UBI is a lazy video game player. That's not the case. But so what? Who are you to judge what people do? Assuming we replace the doll and benefits with UBI and there's no tax change.
Wouldn't compare myself to trump. Just a weird thing
Paul Carlson is OK I guess. Despite his claims, he really doesn't deliver anything really unique or innovative other than his 27V capacitor leakage tester.
What've you got against the ts100 ? 😐
The best settings for the the FFT is 32768 bins don't go higher as the time to do the transform will increase, you can use the Left and Right inputs on a sound-card which gets processed and gets displayed on your computer monitor, FPGA chips are good for cryptosystems.
Dave we show up here for electronic related content.
Is incredible filling the memory card with crap, 3 hours talking for movies, history, astrology, religion but electronic nil!
Why Why Dave? Please make some electronic related videos advance tutorials , Projects FPGA Layout . . .

"australia is the size of notrh america" really dave??? australia is smaller than canada alone
I love your work Dave! You inspire a lot!
What makes me laugh, is that the people who talk about flat earth, do not understand the ideas behind it, and neither do those whom question this idea.
Both sides laughing at each other are as bad as one another.
This guys videos are good but his voice is so high pitch it's like scratching down a blackboard, then when he gets excited it sounds like a screeching cat. His videos desperately need a nice mellow voice over.
Love you Dave, smartest quickest mother out there.
Mr Carlson's as engineer is way better than Dave, he is greet engineer in its field, he probes it every day with its work, as Dave till now only big words for its own but projects NIL zipi di duda. . .
Do you do repairs Dave? I have a Commodore Amiga 1200 that needs it's Capacitors replaced.
Rsi is a fake illness for weak and pathetic people who takes loads of time of work for no reason.
It's a pity time difference don't allowed me to participate .
One love
Since it's second livestream that's timed very badly for EU people i have a suggestion. Would you consider making different livestreams at different times so everyone around the world has the chance to view it live from time to time? I know it would make things harder for you but i'm sure the community would appreciate it. 🙂
