Let's get into what this one's from Stralla because it's possible. Thank you very much. Ke week's Queensland Up Bloody Queensland up. don't know what I'm talking about.

Anyway, let's get into it. What do we got? Simple Oh oh oh oh I Know this comes in a loose green case tomorrow. it's the Vion it's the world's It's upside down. all the electrons gonna fall out.

it is. thank you very much. Can't believe I got one it is Wow the world's Silius multimeter. Um this was a Kickstarter and IndieGoGo thing and there's a huge thread on the eevblog forum about this.

It was just like a debacle and it was just like a joke. It's like a Bluetooth hooks up your phone and it's got LEDs on the top that light up and was supposed to measure all sorts of like stuff. and their app looked ridiculous. and they were there on multiple platforms and they delay after the delay but they to live it.

Hats off. And yeah the threat on the eevblog forums called Vy on the world's silliest multimeter main in Korea. Okay it's a South Korean thing. they didn't get made in China that's interesting.

Anyway the Vion let's go and here it is. Check it out. They actually had this on Kickstarter and also an IndieGoGo cuz you got to get have to sucks of the South these days. everyone does that.

It's all the rage. Anyway, they raised like over half a million bucks total. You know that was a lot of money involved here. Anyway, this was I think March 2018 so it's more than a year so it took him a long time to get it out.

but hey, hats off. they eventually did and there were lots of updates and comments about I think me and O people want their money back. they're like 800 comments which is a lot. Received the Vion it works great.

Still waiting for the refund Anyway, everyone like wanted a refund they requested and vile and said that they would refund money and I'm not sure if they did I don't know I won't go into details Anyway, still waiting for the refund anyone? refund refund refund. And here it is all started by Motley Snickers There's like ten pages of it as we followed the saga over like a year or something. There's just no shortage of face palms and I come in to USB charging port. Yeah, that's what you want.

A multimeter only works when two devices are charged meter plus phone and I love this on the page the rocker I see it's got point seven percent accuracy and I'm yeah and it just promised the world. It really did. Testing the functioning electronic devices with the traditional multimeter is a hazard. Dials, switches, tethered leads and technical jargon.

and complexity and difficulty and keeping track of measurements can be a real pain as well. Now there's an easier way introducing Violin: the world's simplest bluetooth multimeter. That's why unsimplified testing electronics for malfunctions. It can automatically measure electrical output and send data to smartphones.

and the VAIO an app provides you a live feed of all the electrical measurements taken with Violins bulbs. It By Owns Unibody design makes it lightweight and easy to store. perfect for your workshop, your home, or your car. Connect by onto your smartphone using Bluetooth and measure values in real time.
By On reads back stored measurements through voice guidance. So why worry about looking to buy a phone? By On gives you a simple, good or bad result indicator so you'll know right? Lyle time if your device is working properly. By Own has colored LEDs built into the photos for quick visual reference as well Flashing lights for connectivity status Use: buy Into check if your batteries are running low, if your electronic devices are working correctly, or if their wiring problems in your home. By On caters toward both experts and novices and so it's most functions found on traditional multimeters, so contractors and electricians can use it on the job as well as a boy trying to fix it or seek writing.

Reading measurements the fine collects is easy, but for those who like data, you can review all the detailed information displayed in the By Own app. You can automatically detect the error of the device and have the measurements saved on the application. Vayan is the easiest and safest way to troubleshoot problems with electronic lights. Christmas Live iron eliminates the hassle and expenses of calling for repair services.

Anyone can easily use it for countless situations. Gita'. Unlike other multimeters, Biown has no body making its paired probes easy to store and carry. Sure, it is easy to stop by on the world's simplest bluetooth multiple silliest motivator.

And they've got another video here where they duped a bunch of Mechanical Engineering students into like talking it up and I I won't embarrass them by showing the video anyway. Yeah, that's what you want. You want to put your phone there instead of having a multimeter on the bench that's cheap and easy and rugged and just works and lasts forever. Yeah, you want to have your phone there next to your Vion.

Yeah, that's the way out in the field. Do you want to use your phone? What makes Vion different? tangled mess? Hard to use. Our multimeters are so hard to use to put it to Volts in. it gives you a display of volts and no data storage.

Too bulky to carry tangled mess. existing multimeter, positive and negative probes versus the Vayan which has two probes. but their point there is just showing that you know it's either polarity. It's like you can do that on a multimeter too.

You don't have to put it the right way around, you know? has seen now on the Eevblog. Real time storage anyone can use it can be used by the general public and experts. Let's measure your light socket, measure your light bulb, and the applications. All about the app.

We'll check that out and check this out. This is hilarious. It can measure em. Doctors get seen values of Mahendra's solid red light battery adapters DC Solid blue is outlet luminaries AC Detection: Solid green indicates broken objects.
Okay, that makes sense. Existing multimeter fire and it only displays numbers but the thigh on can automatically diagnose and battery life based on and automatically diagnosis and battery life based on measurement Target: What? Automatic detection of Ac/dc and resistance? Yeah you can actually get multimeters that do that that actually automatically switch like the same price or cheaper than the Vion. and I Love this purchasing. You can direct purchase the product from the app.

I'm not sure if they ever got this working but the whole idea is that if it detected you how to blow in light bulb it would automatically order you a new light bulb like it's no idea what type of light bulb it is. So dumb confirming voltage output you can test 1.5 and 3 volt batteries. Can it no? Check that size shape variety for usability. Inconvenient they're inconvenient Size multimeters where maybe it's safe Blue Tech Expert general use on my voice guide store connection Complete detail analysis of your fault they claim in the world for this silly thing for whom Adults, children, grammar and experts Hitler Mustache: This is great.

Oh you're that blown multimeter Look blowing. Are you doing to blow me up your cheap-ass multimeter? And did you buy on instead all? they're spelled inductor right this time. find our automatic detection of. Also, it's a crap voice guide.

It's easy storage anyway. he goes on and on and on and on and on and everyone thought like Joe public thought that this was a good idea. Like unbelievable. No no, just not.

But hey Dave don't knock it till you tried it. Ok well let's give it a burl shall we? Um, the first thing is well this case is kind of nice. Look at the physical size of this thing. It is enormous.

To enter this pokey little plastic thing is just ridiculous. look positive click clip which you can't get out so you toss that because that's just ridiculous. And look at this even if you kept your manual in there. That's ludicrous.

Why? Alright, so it's the via on VMs of V7 makes it sound like they've it's really refined. Oh there you go. You can download the app yourself. manufactured and sold on the responsibility of why Tech Co Is the guarantor of this product slip main body, sub body at like Yeah right? Okay, whatever.

look it says what. Charging instructions p1 P2 p1 3 What? P1 is this one over here? We haven't even looked at the thing yet like I'd like that's just confusing. uh-huh Anyway, you got to recharge it. Alright well the first thing I notice is that the this is like really stiff and it's just kind of annoying.

Anyway, big flexi curly cord on it and it feels very plastic. II As you'd expect, there's the VMS V 7. It's made in that South Korea. Excellent.
My multimeters made in South Korea They make good stuff microUSB B type We've got a power button there. There we go. They're switch it on. How do we do we have to hold it on to switch it on? Yeah, we're gonna hold it.

Oh jeez. I Can barely see that flash in like I like oh there there it is. So if you hold it like that, that's all automatic. That's already a fail.

A product design fail right there. If you're holding it like this, you can't You can barely see that flash. You've got to have it like that and then it appears greenish on this side and well I don't Not even sure that's a flush in blue is it? I think that's supposed to be blue? looks very greeny to me anyway. Oh I don't know.

No, no no no. I Do notice one attention to detail. This one over here has a dual band. This one has a single band that's to identify them.

That's he can't actually push those together can you so that you can shove it up the clock of it like it's not a ring. it's just a lid on one side of the PCB Yeah, Fail already. And the second fail to charge this thing. There's no USB port of course because you can't have a cat safety rated and external metal so you've got to actually undo this.

Does it have a metal threaded? It's not captive so you're gonna lose that screw. Alright, that's gone. Ski. don't know what the battery like? I can't even get that out.

How do you? How do you get that out? There's no like little indent in the plastic. Oh I Figured it out. Look, there's a little fingernail. It's not this part here.

It's that. There you go. Oh goodness, do they tell you that in the manual? They probably do. Yes, they do read the manual Dave right? So there's your little battery little one hand.

and then there's a little microUSB for charging. So you've got to like stick this in at right angles and charge the thing. No, no, just just no. Anyway, there is a metal threaded insert there so that's good Attention to detail.

but like they should have made this thing with like a screw off cap or something like that that had like a single double-a and then a boost converter in there. and like it should have done it Something like that because like like bluetooth. Like moaning even bluetooth multimeters that I take a lot of power. You can run forever on like a single double-a cell.

No worries whatsoever. So yeah, I don't I don't like the rechargeable thing I don't know how long it lasts, doesn't tell you. And on the other one down in there, there's our fuse. None of that.

HRC rubbish glass all the way with LBJ supposed to be a hundred million fuse? Hmm. Anyway, they did advertise this originally as having current capability, but they've removed that. you can't measure current so the fuse is just for its in generic protection on the input well, even when you put the screw in here. I Really don't like that I can prise that apart like that and there's only one clip on the like other side kind of holding it in because I know Roenick Lee You take the screw out of here and you're supposed to prise it up from this side which has the clip on it.
Just no bad design. Now, what are my problems with this flashing indicator? Not only does it work on the other side really, but is that you can't? You would ultimately probably forget what the indicators actually mean for various things and it's actually it requires quite a bit of force to actually pull that apart like that to get your probes. There's a lot of force and that Springs back like that. So if I'm trying to get on the ends of something, jeez, that's it's really annoying.

Anyway, let's measure this battery and we get a flashing red and I presume flashing red is bad. Let's measure another battery and we get a solid red. Well, is that good or bad? I Assume flushing is worse than solid and if we get our 9-volt battery which they show you that you can test in there and that one's a flushing ones. So there's nine, volt battery is supposed to be in the same condition as this.

No, no, it didn't like that. Did it? It had to recover. Let's let's try that again. if we go straight from there over to here.

Oh, it's switched off. No, my finger didn't accidentally press that. it's switched off. Okay, that's annoying.

This is supposed to be super intelligent Smart 9-volt battery supposed to be in the same condition as this. Let's get a real multimeter and let's measure that, shall we? This will be backwards. My 9.6 right? So this is a brand spanking new 9-volt battery. It's flashing red and this double-a it it want to be good.

Wah wah It's not. It's point eight volts so this is bad and it gives a flashing red. This is good. It gets the same flashing red and this triple-a battery.

It's good and it gives a solid red. So yeah, right off the bat, it's failed between single cell and multi cell 9-volt batteries. It's just not intelligent enough to know the difference and let these instructions make absolutely no sense. Okay, blue is AC okay.

Red is DC as we saw. Green is resistance okay and a blinking red blue need to charge the battery? Okay. Red light blinking automatically off. What? Like it doesn't tell you like we're like good bad battery.

Things like that I mean one of the primary uses for this would be testing batteries and I can't even give you I Think this is just a jumbled gibberish I Can't even like to say okay, what does a solid red mean when it's like DC What is a flashing red mean? it's just not. They're stupid. Let's see if we get our continuity. Yeah, eventually there's there's no latching cotton your tea.

There's no buzzer. So yeah, right there. it can't match any multimeter on the market. Okay, supposed to be 300 volt Cat 3 rated.

No independent certification or anything like that. So I'm gonna be brave and shove this right up the mains clicker and then we're gonna whack that in there like that. No. I just switched off.
Damnit. Solid blue. Okay, so it's detected AC But yeah. okay.

Wow survived mains anyway and can we go straight to that? Yep, and if you measure resistors with it, of course it should be exactly the same. It can't differentiate. It can't do anything if it have a buzzer in it You think it would be able to like if you are totally like a different tone or something for different values of resistance. That would have been like obvious and handy.

Let's see if a Meg works. Yep, let's see if 10 Meg does the business. Yep, makes no difference whether or not it's a low value or it's like 1 Ohm it's a short or going up to 10 Meg or whatever. it just shows you a green light I mean me, You would think that you know the least they could have done is maybe had like a bar graph LED display or something like without the phone without connecting this to the phone it's It's borderline useless for anything really.

And one of their big claims is that are well, multimeters are hard to use and difficult and technical and all that well at least you have the knobs switch to V and you know you know that's Volts. you have this switched over to Ohms I mean anyone can learn that and it's obvious. Visual thing: if you just get this out of your car glovebox and go measure something you don't know, you can't remember what these flashing lights do. Okay carry around your manual but it's pretty useless.

like unbelievable. Alright let's give this a bow. I Scanned the Android app and well let's go Open Link: Bio Multimeter install waiting for download verified by Play Protect Who is Play Protect? Yep 2.5 stars out of 24 reviews Mostly one star rating very frustrating to say the least. App would not his store properly create account not in English when finally in the store would be for the device would not pair with Android Sam saying like yeah we're not doing well here we go Vai on login Why do I have to login? I Just want to operate a damn multimeter.

Why? You load up the 121 GW Bluetooth that you don't have to sign into anything. It just works. Turn bluetooth on refresh. There's a multimeter connected.

There it is. It just works. No logging crap? No, nothing. That's how it should be.

Anyway, it looks like there is a skip option allowing access photos, media, and other files. Yeah, why not? That's a reasonable request Location: That 121 GW Multimeter does this as well. It is a quirk of the Bluetooth driver apparently, so it's not like we're doing it for any nefarious reason. It just comes with the Bluetooth driver.

It's it's. just really weird. Yeah, you can talk to David on the Eevblog forum about that if you want to. Anyway, Project Menu: this is a menu list.
Okay, okay. select device logs Save: Okay, this is just the pie chart. Pie Chart: It's a bar graph. A pie chart.

Unbelievable tutorial. Anyway, this lets: hello select device, get in devices blank. Please select one done device. No.

Well, right off the bat. Yep, that doesn't connect. That's a fail. Yes.

I Shut down the 121 GW app. So that's like not interfering. not connected to anything else. And it's just not.

It's not there. It's Turner Turner Oh look, look, it's got a light. It's got a probe light. I Guess Ok, well.

I've turned it off. then on again. select device. Hey, it's close enough.

Nope. there's no list. No, nothing doesn't work and there's reports of other people not being able to get it work. So me fail.

Ok, you can see it. Ok, maybe we got a pair at first. Go to this devices up to pair with it. go over to here select device.

it's just not there. What? What? What one? No. I've tried all sorts of different like you know timing combinations of when to switch it on during. It's like going through the selection discovery process and all that sort of stuff and I just cannot get this to connect at all on my Huawei mate.

Well it looks like winner winner chicken dinner. Finally I Had to try my old Motorola it's running Android I Believe it's like an older dared to definitely be an older version of Android and it's founded. I'm first shot so let's connect and open waiting. All right, that's good.

Zero That was actually quicker than I expected. Actually, not instant. but actually that's not that works. checking electrical resistance zero.

Ohms, all right. three. Meg RG its he. and I you've got to go in to meet abode I mean this one digit of resolution there? Come on.

Whoa. that was the oh no. there we go. That's actually quite reasonable.

Reasonable update speed. Don't mind that device ready are please check socket Marine Auto Manual Devices logs Config: what's in Config Version 1.1 One for those playing along at home, our firmware version. There you go. That's actually quite nice.

Gets the firmware version out of this. No idea how to update the firmware version? Maybe via USB somehow. but by product can we set up the by Product Not? Doesn't even work? What's feed not. so.

One of the big advertised features was that you could buy products cuz if you're tested a fuse or something and it's blowing it slam, how's it gonna know that Just Lipo is blow it like it's just it is. It is so dumb, right? So in manual mode. Now there we go. There we go.

That's not bad. The update rates actually quite decent. Is the voice? All rights go for a hundred. K Well that's why under oh, it's going up, it's going up, It's going up.

That's not terrific Is it? Why is it like creeping up like that and the voice doesn't work like wow, that takes a while. Like why does it take that long and still going? Still, that took forever to come up to that, didn't it? There was obviously some charge sort of thing going on - kilo-ohms Okay, it seems all over the shop when it I II talks and that charging up thing he took a while. Yeah, that voice just doesn't work like a The voice is quite clear, but it doesn't work. It just sort of randomly does it.
Ten point Oh Ten point Two volts. Why is The jumping around? This is a battery. This is the best source you know. Like the lowest noise saw she can get and where you can't even reset that high-low thing.

Sensitivity: What? 5 point 6 volts? What? I Just hit sensitivity and it's now showing me what. Now it's showing 10 Point One Nine, Three Volts Wah-wah-wah-wah A multimeter has one job and that is to measure quantities accurately and this is like what the hell is that? No, it hasn't hasn't looked up. Nah, they did. This thing is O+ say like, how can those highs be jumping all around the place That is just nuts.

There's something seriously wrong with this. See, it worked. The voice works straight before now. It doesn't work like how can you rely on that I Wouldn't trust this thing any further than they can shove it up.

Probes: the monkey's ass. Here's probes: the monkey trying to use it. Yep, dude. look just jumped a resistor.

Nope. let's jump back to voltage. It's not sure. Hello: McFly Anyway, you can forget about the originally advertised capacitor in die Mm Doctor and Dyer D mode.

Um, they just don't work. and I have no idea what power out is. Was it supposed to output a voltage or something? Anyway, it's going to scope. Oh, that's all over the shot.

Whoa. whoa. What's going on there? There's a data point off. There was a data point off the screen there and horizontal plus minus time, plus minus.

That's just horrible. Look, there's a sample off the screen I Just no, no, no, No no, no, no, no Plus minus ten. What? like? And what are those Davitt Like No. And if I go up here and into the logs, function over here.

Check this out. I'm ohms in Nine Point Five Eight: No. That was the 9-volt battery that we were measure in. So it's like it's completely the wrong range, the wrong units, and and look right, it seems stable.

but it did actually jump up to there you go. It did actually jump up to Ten Point One, Nine Volts. And it's it. stayed stable for all these all these seconds.

Like what? the battery can't output temple at 193 volt. This is insane. Five Point Two Six. What? That's just what it and why would you have a min/max associate a different min/max associated with each logged value.

People who designed this just have no clue what they're doing. This thing is just a complete and epic fail all around. The only kind of positive thing I have to say about it really is that I it's a reasonable Bluetooth Update: Speed. That's it.
Everything else Eva wasn't implemented, doesn't work properly, is unreliable Wow This is a complete and utter turn I Don't know how anyone even like it with the lowest level of hobbyist multimeter experience that beginner sort of level or even like just Joe average. He knows nothing about a multimeter can use this thing. And and think that this is and get the warm fuzzies that this is going to do the business for you. It's just it's a joke.

So I'm just not gonna waste any more time, check in, specs, and everything out, like and anything else to do with this. It's just hopeless. Only one thing left to do. Let's rip this thing apart and let's see if it comes apart somehow.

If not, it's dremel time. Anyway, the key case seems reasonably solid enough on the mechanical side of things they've implemented. ok, apart from the air. for mentioned, flip like I don't understand how this is a thing.

So the battery: 130 milliamp hours Almost half a watt hour. So let's just break into that measure: the current consumption. I Don't care about this thing. I'm just going in.

Okay, well, it won't even start up with the burdened voltage of the low burden voltage 121 at GW. So I'm gonna have to whack that over to the 500 milliamp per mode over here. 22 milliamps. That's not gonna last too long is it? With 130 million power capacity, we were only talking like five ish hours battery life I Know it's rechargeable, but that's just nuts now.

27 It's even worse. What happens if we turn that LED on I 429 million There you go. There's your resistance. Five hours Battery life.

That's just another fail of this thing. All right. I Know you want to see some high voltage on this thing. It's supposedly rated to 500 volts.

DC So let's get the high voltage supply here. I'll crank it up a hundred volts. Here we go. Yep, Two hundred? What? 230 volts? What? Yep, there's nothing wrong with my a high voltage power supply our.

but that's it's. 32 volts out You kidding me? At over 100 volts, it's it's out. It's now 5 volts here. Wow Anyway, 200 volts, 300 volts.

Oh it's coming back here. It's a little bit about 400 volts. 500 volts can handle it and I smell any magics. Mic 600 can do it.

seven six and we've reached the limit of my 121. GW Anyway I'll take it back down. It survived but I don't want to smoke it because I want to do the yacht. What do the teardown first? sorry.

Well as expected that's it. On the Probie side of it, just the fuse and Bob's your uncle and after Dremel in it out this is the main board. You know you can only squeeze so much into this. it's looking okay ish.

you know for what it is. here's how input probe over here that's fallen off. they've actually shear off. When was that a surface mount? Okay, maybe I did break it off in the force.

Anyway, yeah, we've got multiple diode protection here so that's all right. Is that a bridge configuration? We can see bugger having the extra but I presume that's a Zetas Zena's Eddie and I are in there. So bugger having that extra protection? No moths? No. Polly Put the kettle on protection.
We've just got input resistors. That's it. A couple of a MOSFETs I don't. I can't read those numbers from here.

Are they widen the Zener clamping configuration? Maybe they're using that instead of the zener? Anyway, at Piers, how? RGB LED Over here they've got a little slot cut out why that trace is going right next to that resistor there. Don't like the looks of that. I was going to say the spacing is reasonable as you can expect for such a teeny tiny thing, but yeah, I don't know. It's probably what what what I expected like yeah, you wouldn't be using this for serious mains use, that's for sure and I doubt it.

So never going to meet any sort of cat rating. We've got some heat-shrink here. This is because the battery sits in there, so that was just a cheap and easy way to insulate the board from the battery. And that's okay.

no worries, it's common technique. It's a little regulator that'd be the battery charging. Yeah, it looks like we got a programming port there, so there's our ground coming in from the other board, so let's snip that off. See what we have under the hood here? What is that? Anyway, there's our there's a little Bluetooth a antenna and of course the one thing you won't find it any of this is your regular multimeter chipset.

Nothing. It's just got the Bluetooth II processor over there. That's it. Looks like maybe a couple of switches or something like that.

Anyway, if you aren't gonna use a multimeter chipset then you have to roll your own and your really have to know what you're doing in terms of multimeter functionality. That's why the end of that was some silly sensitivity setting in the software, which is absolutely ridiculous. No world's simplest multimeter should have like a sensitivity option that can give you the wrong reading. That's just like insane.

They've completely come a guts are on this. not a huge amount of protection. it's sort of like yeah, $2 Harbor Freight but even a $2 Harbor Freight one's got have some sort of varistor in it. Anyway, that teardown really doesn't matter, it's just academic.

As the Eevblog foreign title suggests, the world's silliest multimeter. I am struggling to think please help me a reason for this turd to exist. like even if they implemented it properly. it's just like a silly idea.

All the stuff that they came up for this thing. There are other ones not this probe type format but quite similar. like I Think the poke it is one. It's like a little key ring, one with a little zip out quarter that's designed it.

You know, throwing your glove box or in your pocket or whatever. But any pocket multimeter just there's just compared with this. There's no comparison whatsoever. Why anyone would want to own this? It's just a file in virtually every aspect, let alone all the crap that they claimed during the Kickstarter and IndieGoGo campaigns.
Most of it doesn't work. No capacitors, no inductors, no diodes. I Just repowered it and which one do I choose? That's it's insane. What's got storage scan finished? It no longer works.

The green LEDs coming on. I Don't get anything over here and there it is again. it's way out 95 K That's out by 5% That is so bad. This thing is just all over the shop.

one. it looks like it's 10 ohms resolution. so why even display the three decimal places like that? So I've got it in automatic mode here now and I'll feed in 30 volts boom and your bar graph vanishes to be replaced by this time little text that's ridiculous. And where's your automatic voice? Six hopeless.

and I just hit this over here waiting for load list. What am I supposed to do? Oh God Oh What? What? What is this one person comment share Model: What? There's a kettle to measure. How to measure kettles? It's a flurry tube. What? So these are like just and how to measure battery.

This is just so. What are they trying to do here? Oh What? And believe they are you. It's like they're trying to give these all these weird random examples of antlers. Look, we've got an LED there I See values: Zero zero Step One Two or what value 2105 type AC for a lead.

What? Oh my goodness. these people have no clue at all. So that's your big like automatic operation thing is your select your device, a moto driver battery a battery. Step One: Okay, I'm going to test my battery here we go.

Oh no I can purchase Here we go. We've got the fantastic automatic mode here. Let's see what happens if I Good Good. It's that good.

I Just got my fingers on them. The pros: Bad: I Waiting open it doesn't seem to know what to do. Let's have a look. Zero Point Zero volts.

There is not zero point zero volts in there. There's like point nine volts in that I'm waiting. It can't even tell you that their battery is bad. Are you kidding me? Their big selling application for this thing like automatic detection of products, it just does not work.

This software is truly awful. Maybe I had it back to front. Did I know it can't even measure that purchase Amazon There you go. It kind of sort of works through their affiliate program I'm sure, but they're not gonna make a cent from their affiliate program because this is the most product ever and people are just going to bin it like minutes after they get it.

Unbelievable. This turd said it just shouldn't exist. It is better off not existing then two people to try and you buy this and try to use this thing. And they went to so much effort to actually produce this over the last year.
As I said, like hats off to them for eventually getting a done look at their our production. They designed all this custom test cheek so they've got like capability to design all this stuff. or do they subcontract that out? There are all various delays as there are with Kickstarter campaigns, they have the expertise to do that. Yeah, they don't have the expertise to implement a like even some basic functionality let alone all the ridiculous stuff that they actually promised.

And they did actually keep everyone updated on the progress of this look. They show you all the reels of parts and everything. It's great so you follow it along, but that's the only thing you're gonna get out of this as well as a free lesson in how not to design a product for a niche market. Well it's interesting to follow along about.

like how they got their dodgy parts from Aliexpress and they identified them as I. Don't know some issues and things like that. So they've got the skill and capability to do all this, but yet not to design even the most basic practical multimeter. But before this thing even shipped, you saw how everyone was asking for refunds.

This is why they posted this up on June 12th. We took a gamble and upgrading the product as much as possible before sending out the rewards. However, after additional tests and experiments, we found the performance and accuracy of Vayan is lower than it was initially. You think if you find this to be unacceptable, then we'll issue a full refund.

I Don't As I said, don't know if anyone's gotten refunds yet AC Voltage is 380, not 500. But the voltage rating to this ID It's not a huge deal I Don't think as long as it can do 240 volt mains relatively safely, then you know that's what you care about. Capacitor, inductor, diode test voltage are not available. the batteries are not available.

That's why nothing works. The voyant app is unstable and will be corrected soon. It takes about a month. Well, it's been a month and I've got the latest version of the app and it still doesn't work.

So yeah, like they decided to ship anyway open that they can fix this. The option menu, a scope, and storage function will be reinforced whatever that means. so they've completely coming out. Sauron Not only the viability of this product in what it can do, but just the basic implementation of this.

I Just like, don't understand the thinking behind this, how could any engineer with any sense of using a multimeter come up with this concept? because it doesn't be Bluetooth connected? because well, that's how else are you going to get money on Kickstarter these days? Surprised it didn't have blockchain and graphene in it. It just goes to show what's possible and not just like the concept but all the other software things that they thought that this thing would be able to do all sorts of market segments it would be able to tap into and do. It's delusional thinking, but that's the end result of people who have no clue looking to just develop some product for some kickstarter or whatever and then just going down that delusional rabbit hole I Wait at no time did they stop and think, well, look, hey, this shopping cart thing. It's a bit stupid I Mean it obviously dawned on them eventually.
if you just stuck with something basic and like they couldn't even implement all the basic stuff like hardly any. Practically nothing on this works properly you wouldn't trust as far as you could shove it I'd Just no, no, no, no, oh goodness. Catch you next time. Ah, by the way, if you hadn't guess my rating, that is my rating.

I Mean you want me to get my toes out as well? You.

    I think the concept looks interesting. It might have uses here and there, like part of an EDC toolkit. I don't think I'd use it as a primary tool but I'd be really tempted to toss it in my purse because I always have my phone with me anyways. I wouldn't use it as a primary tool, but for on the go use when you weren't expecting to need a meter it could have a use case if implemented well. I'm not sure this one clears that bar. That case is excessive and pretty much kills the portability unless you want everything banging around loose.

    Plenty of issues with the implementation. For the use case I can see, you can't count on being able to charge it, it really needs swapable batteries. That alone kills it for the one good use case where it might pull ahead of a traditional meter. Excusable as a proof of concept using whatever parts they had on hand just to make sure the idea works, not as a shipping product.

    Funny watching this again in 2023. Yt kept recommending it, even though I watched and liked it already. EDIT: Just checked their domain name – it expired and is available to register!!

    Hey, I got an idea: buy one to use with your uCurrent!

    Yeah, they just took the money and ran. The website has been offline since 2020, and even in archived versions of the site, you don't find any info about who these guys are. When you read the comment pages for the two crowdfunding campaigns, you find the usual stuff. Lots of people waking up to the fact that they have been conned. And absolutely no consequences. Shame on Kickstarter and Indiegogo for enabling such a zero accountability approach. I still wonder, where all those gullible folks come from who still have spare money to throw at such scammers.

  6. Avataaar/Circle Created with python_avatars Mappy Land says:

    kickstarter depresses me so much, because i can't believe how stupid so many people are. stupid, gullible, and willing to back products but not willing to do 5 minutes of research to determine how viable the proposed products are.

    semi 'slick' videos seem to pull in suckers like nobodys business

    What do you think about the Pokit Pro?

  8. Avataaar/Circle Created with python_avatars oetken007 says:

    The RX TX makes me very curious

  9. Avataaar/Circle Created with python_avatars Maximus McFire says:

    I wonder how do people who never used a multimeter designed a pcb?

  10. Avataaar/Circle Created with python_avatars DNB5561 says:

    The ad for that multimeter is just like those infomercial ads to buy the latest laundry soap.

    it's like something that would actually put someone off getting into electronics

    I have an idea for a new product…Exploding toothpaste.

    lol that thing is fuckin abysmal.

    …. A beginner could make something better with an esp32… How do you fuck this up this bad?

    It has flashing LED's! Quick, take my money! I want one with no body! Bodies are always so awkward to get rid of.

  18. Avataaar/Circle Created with python_avatars Banana Joe says:

    In my opinion, the product probably has a use ๐Ÿ™‚

    For example Dave's review was very entertaining – hahaha

    Hey look, it's the multimeter for millenials !!! LOL
