Hi welcome to everyone's favorite segment: Mailbag. Yes, the backdrop is slightly changed. the old electromagnetic poster is back, the Tv, the telly is gone. Um, and yeah, I'm just.

you can see a bit more of the racks now, so let me know if you like it without the Tv. Anyway, let's get to it. Mailbag. I don't have anything, but there's the shelf.

There's the mailbag shelf. It looks pretty darn full, having a hard time fitting more stuff under there. So let's just grab the first cab off the rank. I think it must have come recently.

So sorry if you've got something down the bottom, it's just convenient. Let's go. thank you very much. Uh, moments in etched in time.

Um, John Revel. Thank you very much. From Um. Silverdale Here in New South Wales, Australia, not Austria.

If you want to send something into the mailbag, Po Box: 7949 Norwest, New South Wales 2153 Australia not Austria. All right. So let's crack it open. Moments edged in time.

What is it like? Is that his company? I? I don't know. It sounds sounds cool. So let's have a look. We've got a note.

You know I don't want to read the note yet. don't want to spoil up. Oh oh thank you. That is an oh look at that.

Beautiful. Oh that's that's it's. etched moments etched in time as an Ev blog etched. Oh oh look what's on the back? Oh beautiful.

Um there I assume like a laser etching merch company that is absolutely fantastic. What's in here? Ah, I can't imagine. black plastic thing. Oh oh, look at that.

Okay, cool. It's etched. It's an etched delorean and that sucker. this sucker is nuclear.

It is going to light up. I assume this is like an edge light thing. Oh, that could make a nice ornament on the side. Yeah, I know I've got to power up the time circuits.

Yeah, I know I've got to fix my uh, 10 100, 000 subscriber nixie tube counter. Oh oh, there we go. That's better. Oh schmick ass.

So that's going to sit in there like that. It's got a wanky remote control. There's the mailbag crawl from John. And sure enough up.

Yeah, this is his company. Uh, moments etched in time, dot com, dot a u. Check it out. Normally he doesn't do the acrylic displays like this, but if there's enough interest he will.

He reckons those, um, thermal mug things. They're a Goa and all sorts of other stuff. So you can do your online designy uh, type stuff. So very cool.

Thank you very much John. Let's check it out. Oh yeah, look at that bad boy. We're in strobe mode.

We can go in flash mode. We can go in fade mode using the remote control. We can go in smooth mode. I can't see the colors because I've got um, edge detection on my camcorder screen and it just all shows up as red.

So because it's just detecting the edges and if you just want red, green, and blue white, look at that. Beautiful! What a Bobby Dazzler. Well then you got programmable buttons. Thanks John.

Check out the website down below. Next up. I already opened this one because they didn't put mailbag on the front. Um, you've got to put mailbags.

I get stuff sent here. Open it. accidentally. I knew it was a mailbag.

Thank you very much. Person Unknown: Um, no, it's not a Cisco thing. It's a Cisco box. So we've got a someone there.

Anonymous thank you very much. Anyway, let's have a look. It is a rack thing. It's a C-class encrypter cabinet.

Installation Notes: I don't know what. What is a C-class encrypter cabinet? Why do I have a front panel? Purchased an Australian ex-government secure 19-inch rack. Found this panel and manual in the bottom. raised more questions and it answered Okay, so this is not really.

This is like asking the question, what the heck is this thing? Um, it probably came on one of those you know, surplus auction things. You get a whole pallet load of stuff and this was probably in there. So they're wondering if I or any Eev blog viewers have, uh, seen or mentioned decrypter or even operated one. Either way, I hope you might find one in the dumpster, Dive into the business park.

Maybe. I don't know. That's what it looks like. It's a a secure 19-inch rack, mounting plate racking kit and got things like encrypter box and stuff like this.

If anyone has ever seen something like this, I don't know what's an encrypter? Um, that probably fit. You know, some sort of secure military communications or something like that and and it shows. Like a thing in there shows like a something. Some sort of widget.

I assume that's the encrypter and uh, like. I've worked in the military and I've not seen one of these. um, encrypter boxes. but I haven't worked.

I've worked for military contractors. uh, before. Not for the actual military. Um, so there you go.

It's A. If anyone has any clue, please leave it in the comments down below. Hi to all my viewers in Germany. Thank you very much.

Uh, you Roger. I'm from Oberet in Deutschland, have not been to operate so there you go, let us know. Okay, let's open it up. see what's in here.

We've got no oh uh yeah, what's going on here? Don't we're gonna have to cut through the box. Hi Dave, thank you. Oh oh. Spoiler alert.

Spoiler alert. Why'd you have to put photos on the top? really? Hang on 1970s? Ah, slightly out late 60s Russian Tt3? Um. tester. There you go.

Even the older Tt1 versions also existed, as well as the more modern Th4m variant. Check out that. have you ever seen a dial like that before? I have not. That is seriously interesting.

Built like a brick. Dunny too. Let's tear it down. Now we have a schematic.

Oh yeah, there's not much in a analog meter, of course. Yes, This certainly is an interesting range switch. uh, design. And there's some pictures here.

I'll link them in down below. and uh, the back plane with specs and range is missing. The instrument seems to be in working order, but the needle is impeded by the flaky varnishing covering the scale. Oops, Um, two minute tear down.

Thank you very much. You look at this. Ah, what a Bobby Dazzler. Um yeah, I've not seen a range switch like that.

Wow. You can use it one-handed Right or left-handed Wow. that is. That is sweet.

That wins the award for the funkiest rain switch. But uh, there's there's some indent there. but uh well yeah, I can hear a click. hang on.

Yeah, yeah, I hear a click sometimes. Well, the range switch is old, but jeez, times. 10 to the power of four. Fantastic.

If you don't know your powers, you're screwed. Does that mean the scale is 100 microamps? Uh, so that would put it at uh, 10k. Ohms per volt. Not exactly the most sensitive uh meter out there, but yeah.

look at you can see inside there how it's all like cracked. It's a no. You're like like all flaked up. As he said, all the um, like the varnish.

the varnish is just flaked inside there. Wow. and uh yeah oh oh. I thought those connectors were a bit how you doing.

They're not those binding posts. They're not They're they're supposed to be on an angle Like that. They looked. They looked a dodgy ass.

but they're not supposed to stick out. Oh wow. Hands up. Um, if you're from Russia and you use one of these bad boys and it takes two 1.5 volt batteries and they're these.

look at them. Um, the Atc brand Super made in China? Um, so yeah, not original, Uh, Ruski and um. R10s size A332. I offhand, I don't know that one.

Um, I don't think I've ever seen that size in anything. Oh how I wish this was smell-o-vision Oh the the gorgeous like oh, smell coming out of that when I took the back cover off. Oh, it just wafted everywhere. Oh gorgeous.

Anyway, look, we've got a little internal, uh, trimmer in there. Um and yeah. wow. it's all rain switch isn't it? And are these wires? Actually, I don't know how they terminated.

They're pretty, how you doing. Um, are they like a crimpy thing? Or they are solder on the other side? like a solder tab buttony thing or something. But wow. Check out our resistors here.

Look at these. I don't even know the name of that uh package. if you do leave it in the comments. Probably did you know 40 years ago or something, but you can see.

yeah, that's really something, isn't it? Wow, they're actually pretty small. Those resistors. They're remarkably small. Then they've got, uh, bigger wire wound ones here.

obviously. Then you get some of your more conventional looking ones here. So yeah, they're what you're familiar with it. Uh, that's interesting, isn't it? And they've used dumb sleeving over there to prevent shorting.

But it's all pretty how you're doing hand wired. But uh, that's the case for all these. um, analog, uh, meters. Even like the super, uh, quality ones, You look in them and they're all, you know, hand done and wired.

Wow, that really is something And so is the smell. So what's the smell? If anyone knows a place, um, preferably in Sydney where I can get like, smells, odors analyzed, I've wanted to always want to do a video on what is that electronic smell you know and actually get it like chemically analyzed this would be a perfect candidate. So thank you very much you that's absolutely fantastic. That is a Bobby Deslar that is going straight to the pool room.

Uh, that is just a magnificent rain switch. Wow, it's you know seeing better days can do with some, uh, oily. but and yeah, give it a bit of a jiggle. and yeah, it's probably not the it's probably not the best, probably never was the best.

but that's not just age. I think that's part of the design, but like, ah, like like it's hard. Like you've got to feel it. You've got to actually like I can feel this thing and I can hear it clicking over.

You're probably not hearing the faint clicks, and you're not feeling the faint little indents and stuff like that. But there are indents there. Like there's not one there. There's one there.

There's not one there. There's one there. Not one there. And there's one there.

Oh, actually, that indents every second. One indent. No indent. This will be indent.

Yep, no indent. No, this will be indent. No. Oh yeah.

yeah. it was. no indent. Oh barely.

No, That can't be a pattern. surely. No, I'm just imagining things. Anyway, that's awesome.

Another sucker. The Sav from Germany from Olsdorf. I think I've heard of Olsdorf. Anyway, Um, how do I? How do I open this one? Oh, it's got a Terry.

I don't need the knife. Look at that. Bobby doesn't Okay, let's have us. Oh oh.

something's framed. That's heavy. Whatever's in there. What is in here? Oh oh, in memory, Bob Weidler, look at that.

Oh, that is a thing of beauty. Joy forever. Wow. Wow.

Bob Weiler 1937 to 1991 Integrated circuit pioneer. inventor of the basic building blocks of linear Ics, including the widely current source and the wider bandgap voltage reference. That's a Pcb that is really Schmick. Okay, you see how they've done that.

Hi Dave. Given your recent problem of remembering names, it's not recent. I've always had a problem with names. Um, you know, if you're like a name person or you're not, I thought you might appreciate this.

Unfortunately, I could not supply these parts at the time of shipping. Unfortunately, you have them in parts been somewhere to populate it. Oh okay, so yeah, the footprints are on here. The idea is to actually solder on the parts into the footprints.

Um, if I can, I'm gonna have to get originals now to complete this thing. Or you could try to get the extra mile. Hand down some of the first production year codes. Yeah, that'd be great.

I'll post the Gerber data in the forum when the mailbag episode goes live. Thank you very much. Uh, best Regards: Breaking Ohms law. Um, that's a forum handle at the Eev blog forum.

so I'll link it down below. That's a Bobby Dazzler. Now you're ever going to love or hate how uh, this has been done. But I like.

yeah. Anyway, we talked about this on today's Ann Power um, the podcast. If you don't know, I only been doing it for like 10 years, myself and Chris Camel. Um, yeah, we actually talked about this.

Chris thought he was a bit triggered by this, but we actually talked about uh, different techniques for uh, doing art like this on uh, Pcbs. now? Um, you can actually do with a standard Pcb. You can actually do five different colors in quote marks. And by this I mean right.

This is a standard, uh, this is a matte black solder mask with a regular white uh silk screen here. which by the way, um, linear voltage regulator. Not sure what a linear linear voltage regulator is. Um, yeah, oops.

and by the way, yeah, um. Unfortunately, the Pcb manufacturer has put their, um, a batch code up here, which is really annoying. Um, some manufacturers will give you the option to actually remove that. um, others.

well, good ones actually won't put it on it at all. Um, but yeah, it's um, although I can't see this fitting on like a regular panel, I think this would have been a custom jobby. Anyway, um yeah, really annoying. They put their mark up there, but you can tell them if it's important, if it's a front panel or something you know important like this, uh, plaque.

uh, kind of thing that you can tell them not to put their batch code on there. So, or you can tell them to put in a specific location. um, by the way. Anyway, you can put those in your instruction notes.

but anyway, you can get um, five different, uh, colors so to speak. When doing this artwork on a normal Pcb, of course you can get a multi-pass process for your silk screen. so you can actually get different colors on your uh, silk screen overlay. White is just, you know, happens to be like the default uh color, but not that they do actual silk screens much anymore, it's not the process, but still silk screen anyway.

Legend Overlay: You can actually get different colors and they can actually apply that as multiple Uh processors. So you know, some manufacturers have, you know, might have half a dozen different colors to choose from or even more for your Um overlay. so you can actually get that. But yeah, it'll be every overlay.

Every extra processor gotta pass it through for the different colors. Kaching jing on the cash register. But anyway, so you can get five different colors so one is your white um overlay like this and then you've got your solder mask color. Whatever happens to be solder mask.

This is a matte black. You can get a gloss black. You can get your traditional green. You can get reds and yellows and bloody purples.

These days, everyone's doing bloody purples and god knows what color you can get pink ones these days. Oh god, when I was a boy, it was green. Take it or leave it anyway. So that's two colors.

and then of course. um, you've got your uh, just your bear. Even your bear Copper. Um, so you can do like solder mask over bare copper.

Um, and then they'll give you bare copper. but then that, of course will corrode extremely quickly. So this one, of course, has got gold. Uh, flash on it.

Um, so yeah, it's just a regular uh, gold-plated board. It's not that huge amount extra. Um, and yeah, so we've got our gold there. but that's basically just you know, copper.

sort of goldy color because it's not really good quality gold so it doesn't look like real gold. But anyway, let's not go there. And so you've got your gold color. So you've got your one, two, three colors and then the fourth color is the bare fiberglass in here.

Now, Um, you might be thinking, well, are you Dave, You said five colors? How do you get a fifth color? Well, if you actually remove the copper from the back of the board, it will look different than this. I mean, this is, uh, well, Unfortunately, we'd have to take this out, won't we? I presume that is entire, uh, copper on the back there. But of course you've got the uh, black, uh, solder mask. And of course, if you're doing this board, you might do it as a single sided job and but you wouldn't really want to etch off.

You wouldn't do it. do a double sided and then etch it all off because then they'll get a bit nasty with you because you're wasting all their etchant they have to replace it quicker. But anyway, you can get different, I guess. Um, translucent properties of the fiberglass.

Depending on the backing you've got, the copper or the solder mask, it doesn't Doesn't really matter whether it's solder mask or it's uh, copper, it's You know it's going to make it. um, you know, just appear dark like this. But um, yeah, If we didn't have anything behind there, then it would appear lighter. And of course, you can actually light up from behind as well.

So you can do all sorts of arty, farty things with um, Pcb materials. You can light them up. you know, you can put backlit leads on the back and actually shine through the fiberglass material. and you can do all sorts of jazzy stuff.

But yeah, with a standard Pcb, you can actually get five different colors. So anyway, I'll link in the Amp Hour episode if it's out by then and where we, uh, talk about different, uh, processors, uh. potential for doing something like this. Anyway, thank you very much Breaking Ohm's law.

That's going straight to the pool room and I will have to try and source. Um, the Lm10 uh, the Lm100 and the 702 as well. Of course you know you didn't try. The Holy Grail would be to get the uh, original.

You know, a launch year date? Um, you know, like an original? Maybe an original week? You know, first week it was released or something? I don't know. And hands up, if you've got, um, like the original release date um, version of these devices, that'd be awesome and then you solder them in there. and Bob's your uncle. Get it.

Bob. Good on you Bob. So yes, Breaking Ohm's Law is on the Eevblog forum, as is everyone. so I'll link in.

I always link in a video. uh, link a specific uh thread on the Eev blog forum for this video and uh, breakinghomes. Law said it'll put up the Uh files for this if you want to get your own made. Awesome! I think this has been sent to the wrong address.

I checked with the Hr department and there's no Mr. Ac coupling here, so I'm gonna have to send it back to uh, Jb J Fourier, um in Paris, um the postcode 1768. Um, or should I just open it. Let's just open it.

Got a case. Oh okay. it's one of these Tens things. I don't know.

I've never. Well, no. technically. I kinda.

I think I did use one at the physio. Or the physio used one on me once and bloody hell it hurt. Um, I was trying to rehab my knee and uh, it's one of these Tens machines. needs two nine volt batteries.

Does it? I guess? Yeah, that looks pretty old. Neuro track Tens machines will do. I believe that's meant for a two minute tear down. So this comes from a medical company in the Uk Verity Medical Neuro Tens.

So Tens machine? it's Look, you know it's I don't know the it's anyone. Yeah, 15 Really? Okay. It just. it just seems old.

Like it just seems like really old. Like you know, 90s or 2000 vintage or something like that. Just seems to be like the cream colored thing. anyway.

Um yet there's two probie uh interfaces like that and so they go into the unit. Then we've got some two millimeter jacks like that. 2019? Yeah, they've expired, but we'll see if they still work. Got the original manual, the quick start instructions for those playing along at home.

And there we go. You can now. it looks like you can set the current and stuff. You can set the frequency.

Um, I don't know. Pulse rate. How do these tens things work? Um yeah. They put like pulses into your muscles and stuff.

And we've got the actual Uh pads there too. So sticky adhesive pads. I guess you can. Can you only use them? No, these are reusable, right? I think that.

yeah, they got oh oh yeah. um. oh I think that's sticky. Oh, that sticky gel is.

Oh, that's seen better days. I think. I don't know. I can stick it on myself.

But really, there you go. Works like a bought one. Yeah, no. five.

five milliamps on here. There you go. This one will go up to six. Oh, I can't You can't even go to 11..

So here's all the different uh modes you can get. It looks like you can't like do a custom one. I think they're all sort of like a preset. All you can do is adjust the current amplitude basically so.

Burst Mode: Short burst of nine pulses. Modulation: This was designed to help prevent nerve accommodation that some patients experience, achieve by continuously striking the pulse width and rate. Oh okay. no yanks allowed.

You can get uh, different diameter, uh, pads and stuff like that. And uh. there you go. You got fingery problems, knee arthritis, a new blood? yeah, whatever that is.

Um, Cervical problems? Um, yeah. over orbital. Yeah, I want to fix my over orbital. If you've got menstrual pain, There you go.

Feet pain, Toothache? Really? I didn't. I could use a Tens machine for toothache. Really? Is that a thing? Hands up if you've ever used a Tens machine for toothache. So this is what the waveform looks like on four milliamps.

Uh, 100 Hertz, 200 microsecond, Uh. pulse. And there you go. So it looks like they stagger.

Um, the pulse on each channel Like that? There you go. So that's what it's like. I mean, it's it's saying. 50 uh volts per division? Um, a 100 volts open circuit? That's have.

I got my probe. I think I got my probe settings correct. Yeah, I just realized those uh pads expired in 2016. So yeah, that would be like the, uh, conductive, um, gel.

The conductive sort of semi-adhesive tacky gel that they have on the bottom of them. They've got a shelf life. obviously. No, I thought I had them crossed.

but I didn't. Anyway, there you go. Um, so now we're at the So. I'll put a 4.7 k uh load on there and now I've got there you go.

Second channel max 5 milliamps, And there you go. 100 millivolts, uh, per division. So that's what we're getting. But now they're actually lined up because I've actually got Channel one turned off.

so that's actually being picked up. I'm adjusting it now. Five Milliamps. It's gone back to six.

And then seven. Eight. Oh no. It can actually go up.

Look. oh, it can actually go up Ten. Ten milliamps, It can go higher. Whoa.

And then this. This one's changed. Look. as I change channel one.

Channel Two is I think it's Channel Two that's changing. Yeah, So yeah, that's almost as if there's like that's a circuit problem, right? Whoa. Check. Check that out.

Okay, No. There we go. Whoa. One One milliamp, there we go.

Okay, no, I was just looking at that. Okay, so it looks like that we have some crosstalk happening here between channels. So I checked. and, um, sure enough.

Uh, the open circuit. uh, tens. voltages are typically like up to 100 volts. so that's really what we'll see in there.

Of course, they don't have the capability to actually deliver that voltage into load. So these things are designed to be. you know, relatively safe. Although you know you probably wouldn't want to whack these things across your heart, tear down time.

There's not much in them. Um, yeah, we've got a micro in there, probably got some Op amps or whatnot. And uh, then here's our step up transformers for both channels. and that is that? Just like an output choke or something? I'm not.

uh, not entirely sure. A couple of big ass caps flapping around in the breeze there. and yeah, not a huge amount. But yeah.

just got some step up transformers and um, then they just control the Uh primary side. um, a pulse shape and that. just. and they step it up.

On the uh secondary, there's the micro. It's got some crusty stuff on it. Um, but it's a Samsung Jobby. I don't know that offhand.

Uh, Bueller Bueller. It's got an Lm393 there, another 393 there, and a 4013 4000 series cmos jobby. Oh boy, that's hilarious. So yeah, there's nothing doing in these things at all.

really. Um, yeah, I think there's lots of like do-it-yourself tens kits around isn't there, but I'd like. I'm sure like the this one would have cost a bit of, uh, coin I think. but you know you can get some.

like really el cheapo ones. can't use some uh, cheap and nasty ones. That's what you want when you're sticking electrodes on yourself and uh, you know, and stimulating your muscles. Um, yeah, I can remember.

I had my, you know it was done on my knee. That was like it was really painful. Um, they they turned it up to 11. in dermatome charts.

Um, these bad boys are, um, what divides your body up into? Like each section of this has a specific Um, input on your Um. spinal column? Your like nerve? uh, impulse on your um. spinal column. So this is how your body is actually divided up and this is why you can get you know, numb in some places I guess and uh, you know, not in others because if you damage one of those, um, you know, spinal receptors or whatever.

I don't know, um, my physiology. But yeah, if you want to damage one of those, you can actually get numbness in certain areas of your body. And this is how they divvy it up. Yeah, I'm guessing.

uh, you know you don't want the old S3 to go there. That'd be a bummer. Oh, there you go. I forgot the specs.

It can actually do zero to 80 milliamps into a 500 ohm load. indicate. Actually, milliamps will tend to be less than indicated due to electrode impedance. Um, yeah, at a thousand ohms load.

Yeah, yeah, et cetera. but I'm jeez. that could do. I can do a lot more than I thought anyway.

Um, yeah. Constant current, maximum output voltage? Um, so it's open circuit compliance voltage? Yeah, 180 volts. There you go. So yeah, we'll certainly uh seeing that.

Yes, it's actually a rather little grunty device, isn't it? Hmm, so I'd give it a go, but I don't have any pain at all. really. Um, even after going to the gym today. So yeah, I don't know.

I'll definitely keep this. Um, four? Yep. and I've got. I've got four pads.

Um, so if I need to, who cares if they're expired? I don't know. Just stick them on with some gaffer tape or something. She'll be right. No workers.

Um so yeah, thank you very much for sending that in. Interesting little tear down these Tens units. Hands up. If you, uh you I know a lot of people use these so yeah I know, uh that a lot of people like swear by these things to uh you know I give them pain relief and uh stuff like that.

um all I did was for me during rehearsals just cause pain. um no yeah they what they were doing with like I had like a much like a much bigger machine than this that they hooked me up to came on like a cart and everything. um and I think because they were doing muscular rehab there so I'm not sure if this these ten units can actually do that muscular uh rehab stuff. and I think a lot of uh, sports people uh use the high-end ones don't they to actually stimulate and build the muscle because you can actually do like a workout.

It actually contracts, uh, the muscles and you can actually get your muscles to actually do a real like strenuous workout by hooking up to these machines and you can do it. You know, faster, better, safer or whatever you know. especially if you've got if you're rehabbing, um, something. And yeah, I'm not sure if this could do it.

I don't know. maybe I'll have a playing around with it, but I don't know if I'd be able to make my muscles twitch or something. I don't know. if you want to see that, maybe second channel video, perhaps? Leave it in the comments.

This one's from Shenzhen Probe Sound Co-limited Uh, not from China from Hong Kong. So let's crack it open and see what we've got. Got that nice, uh, Constantine foam thing. I do like that and that's it.

That's it. There's no note. Oh yeah, I think I yeah, I think I remember what this is. they emailed me.

let's have a look. Tada, what's that's a belt clip? Nice, it is. Oh oh gonna say that's a little bit hefty. Um, Probe tweezers? Let's see if it comes on Lcr Probe tweezers? No.

I might have to install. I might have to switch it on manually. I may have to install batteries. Um, this is interesting.

It comes with a looks like a little calibration. well, not a calibration board. like a little test board or something. So that's pretty cool.

And it comes with a Usbc cable. Okay, it may be flat. I'll have to, uh, charge it up. but um, these are the Shannon Tweezers.

they're called. so I do have a whole bunch right down here. Lcr tweezers. and here they are.

I was going to do a uh shootout. We've got some a Global Specialties one Lcr 58. Um, this is just yeah. if you want to see it coming.

Um, of course that's the um, I can't remember. that's the uh. the smart Tweezers one. Uh, then we've got the other, yet that was the little rotational uh one.

That's the Um E Design one. Then we've got the made in uh, Canada one as well. And um, yeah, I think there was. I should have opened this.

um, Digital tweezers. Oh okay. Another mailbag. I put it down there thinking I probably wouldn't do a mailbag thing.

So bonus mailbag. Let's open it up and uh, see who it's from. Oh, it's another E-design one, right? That's why. um, oh no.

I thought, hang on, It says multi-mm digital Tweezers tweezers. So I didn't even open it and I put it down there with the other Lcr tweezers. and it's a mini Wear Ds212 digital Storage oscilloscope. Have they mixed up the boxes or something? Is it actually? no, I think it is.

I think it is the it is The tweezers. Okay, they've put it in the oscilloscope box. So yeah, I think yeah. they sent a new version because I destroyed didn't I? yeah, I physically destroyed my other one.

So there you go. Now I've got six Lcr tweezers. I will give you a quick two second look at this one. I won't do a tear down or anything, but we'll just have a go at it.

But I've got six different Lcr tweezers if you wanted. Add another added to the shootout list, leave it in the comments down below and thumbs it up if you want to see it because if one person just puts it and nobody thumbs it up, then so here you go. We've got the uh Shannon tweezers as they're called. Um, and interestingly the Shannon tweezers actually.

um, started on the eevblog, uh, forum and their website actually. uh, links to their main page. links to the Eev blog forum are to get information and discussion on this thing. and uh, it did switch on.

Before there we go. I plugged it in and it's now charging up. Yeah, I assume the battery is a little bit, uh, flat. There, it came out flat.

But there you go. It's got like one femto farad resolution there. point double, oh one uh, picofarads puff. So there you go.

and if we it's automatic. Of course it's uh, up to 17 meg or whatever. There we go. 17 millions, 20 milliohms or whatever.

But yeah, it looks and feels like a quality bit of kill. I really like it. Is this a yeah, yeah, this was a joystick in her face so I have not read the instructions. Of course I haven't but uh, did that have Diode mode? Esr mode? impedance mode? Yeah, nice.

And it's got the uh, it's got the graphic there showing that and also our test voltage as well. Anyway, the probes look and feel really good. This is not going to be a review, I just wanted to give you a look at it. um, their website unfortunately.

uh, it seems says mentions the components shortage so you may not be able to get one. um as of in this video. But anyway. um, definitely work.

Worth the squeeze. uh, firmware version one. So this is like this is early release. uh stuff.

But there you go. There's the quick reference card. I like to like the symbol up there that's neat and it's a nice simple reference card there. Neat.

Oh, and then a graphical tree of the menus. Um, sweet. So can we just put that back and just hold that and put it into auto mode. How do we go to auto mode? Hey, auto Mode? There you go.

No wackers. All right. So this is 10 puff. There you go.

10 puff? No worries. 100 nice. Let's go all the way up to one mic. Oh, I'm getting ripped off there on the one mic.

but you know that's not these tweezers. That's um, the actual cap. They've got massive, uh. tolerances.

Here we go 95 getting gypped again and we've got one milli so it can do some high values. Nice. But typically these Lcr tweezers like you, you're targeting our surface mount stuff in, uh, production testing, production sorting. You know, stuff like that.

They're really handy. You should actually get a pair like an Lcr tweezer thing. I think it's an essential bit of uh kit these days. Um, for any lab because they're You know, they're reasonably priced these days and uh, yeah, no workers so can do it.

Can it detect a lead? or automatically? let's have a look? don't think so. I wouldn't expect it to just a regular diode. No, Yep. Inductor? No worries.

It's got cow menu uh, instructions on the back, so I assume this is uh, supplied with it. Ordinarily is it? Anyway, Shannon tweezers looks pretty good. Um, then please. The thumbs up in the uh comments leave a comment.

and if enough people thumbs it up, I'll get off my ass and do that. Um, Lcr? uh. tweezer shootout. Very quick tear down there.

It's got two big ass screws holding in the bottom that must be holding in the arm of it. Oh geez, that looks really nice. Anyway, that's our buzzer and uh yeah, we have to get the ball. Yeah, we have to get the board out there.

You go. What processor is that can't read it on my camcorder screen here? But uh yeah, that's all she wrote. Geez, there's not much in it, is there? All the smarts is in the software. It's a really hard one to read.

Electron Cloud, Inc. Electron Cloud Ec1421 Electron Cloud Ec1421 What the heck? Never heard of it. Yeah, I have no clue. Um, what that is whatsoever.

Bueller Mueller, Mueller. Um, yeah, no idea. Anyway, Um, yeah, that's pretty cool. Um, I'll leave the link to the Eevblog forum down below and the website of course.

Um, and maybe you'll be able to buy this soonish. Oh, you can see my macro lens catch you next time you.
