Hi welcome to the mailbag segment. Again, Yes, we're straight into it. Here we go: This one comes from Silven Mania Sorry Silvane, because um, this one was the 1 of March It's been sitting around here for a while. Priority: Oops Yeah I'm sure it got here on time.

Um, slack ass me hasn't uh opened it says thank you very much Silvane and whoa, what do we got here here? We go wh obsolete Electronics You know we love obsolete Electronics Printed Matter Parts and Sacm bag no I'm sure that's just the generic form. There you go. let's have a look. Obsolete Parts We do love obsolete Parts Here on the EV V blog everyone loves obsolete Parts Maybe it's some vintage Tech or something like that.

Let's have a look. What do we got? a there a box inside a box. we have a Transformer Wa that's a weird one. Yeah, it's got one of those weird overseas plugs linear Transformer What do we got here? Let's have a look.

o What's that? Looks like something from a Car 2 * oh that's there we go. 2 * 21 + 4 3 Watts So is that like an audio amp or something like that? that that looks Russian There we go Cccp, We got some Russian stuff. Let's have a look. we got.

who. What is this? What is this ancient? I Have no idea what those cans are. They're uh oh, they're actually uh. got leads on all sides.

Look at that ancient. Just a um, tin plate of course. no solder mask. Nothing like that.

Absolutely ancient I wonder what that plugs into I Guess we'll find out. I' got some ancient a ancient Parts here. What man. look at these.

It's got that crusty old smell. Hang on. Oh yeah, crusty old Parts smell I Won't uh, take those out just yet. but we have a whole bunch of maybe there's a note in here.

Yes there is. Let's read the note. it's tear down time again. Hello from France I Follow your blog Since a long time, my main hobby is collecting unusual Electronics Awesome! From pacemakers to Aonic, including broadcast cameras and any kind of stuff that is not available at your local retailer.

I Included in this parcel: a Yugoslavian Made digital multimeter. Wow! awesome with its power supply and user manual. I'll have something for today's tear down Tuesday because it is. it's not mailbag.

Monday It is tear down Tuesday and I've started late. it's 318 p.m Oh but so I was hoping to actually find something in the mail bag to tear down. So here we go. Great, it will be Great tear down review so it may contain lots of weirdness W For a quick tear down, you have a blinker module from a Russian L car all right made.

Made sure to check the power rating formula engraved on the box and a special Factory logo hybrid modules you will find inside I also include a circuit board from a Soviet ah electronic calculator, an Iscra 1111 I think I may have heard of that actually featuring unique Lwi integration hybrid modules. So that's what they are. There you go: Low integration hybrid modules neat from an electronic calculator, a bag of random Soviet P CU I Believe such things must be such things must be somewhat rare to find. Make sure you check out my flick up photo stream I have thousands of nerd porn related photos? There you go folks.

I Will um, no doubt, post this uh link down below so you can directly click on it. but um, check out um San's uh, photos of all his retro Portland Fantastic. Thank you You very much sane I Hope I'm pronouncing that correctly. Probably not.

You know what I'm like with pronunciations I absolutely suck at it. So let's uh, have a look at this. Oh, we get the manual and everything. Look at this.

Fantastic. Brilliant. Oh, look at that. There's the block diagram.

Tada Brilliant. Oh, and schemati atic schematic. We're in. We're in like Flynn look at that.

I'll have to, um, scan that. Actually, what I'll do is I'll um, scan this in and I'll put it up as a uh PDF um available Rather than you having to uh, squint everyone having the squint in HD there lots of oh look some uh J fets on the input there have we got? Oh there we go. There's the input protection circuitry anyway. um may or may not go through that.

What we want to do is have a look at this puy and uh, will maybe the subject of today's tear down. Tuesday So I may not do anything with it in this mail bag. So sorry about that, but uh, tough titties. Everyone will have to watch it on the tear down.

In fact, this may actually go up before the uh oh look at that may go up before the uh mail bag. Brilliant. Oh that is. That's terrific.

Oh that's a bit. that's a bit crusty that range switch, but uh, looks like what is that a lead display up there? Check it out. All right. It's got a 2,000 Volt range.

Very nice. That's a really unusual 20 microamp range. Full scale. Fantastic.

You don't get that much these days. That's very nice. Right up to two amps. This is actually quite a useful meter.

I Wonder what the specs are? This isn't bad folks. Check out the specs look plus -2% of reading .1% full scale. Uh Tempco from 0 to 55 is uh 2% per uh 10 Kelvin There you go. Terrific.

That's not a bad multimeter at all. I wonder what is the age of this thing? Has it got a uh got a like a copyright? No? No. I don't see like uh, copyright age on there. Is there a date on the schematic at all? This is in really good Nick I mean both the meter and the Uh manual? Fantastic Look, there's no yellowing on that or anything.

All right, let's pop this puppy open, shall we? And uh, see what we get? It's a blinker module from a Russian ladder? All right. Tada Look at that electromechanical brilliant. This is really rather fascinating. We' got ourselves five terminals here.

I Have no idea what voltage Lad Car works on I'm assuming it's a single 12vt lead acid just like, um, other? uh, well, most other cars. Anyway, looks like these two up here are the contacts. Obviously, there's our contact and uh, that is. So let's have a look under there.

Ah, look, we got some red solder mask under here. Look at that. It's like, well, it's actually more than solder mask. It's like it's um, conformally coated or something.

It's been put on there after the thing's been solded, so it's like it's been like painted on. Um, if anyone knows what type of, uh, material, um, that is. Is it like a is it like a, you know, like a similar like a polymer solder mask or or something? Or is it just a lacquer or whatever. Um, please let us know if you know your vintage electronics and that ladder cars.

but um, yeah there those contacts. I Would have thought that they would just be, um, well, contacts I wouldn't think they would be going to anything. so that's uh, that's kind of weird. I didn't expect those two terminals there to buger off over to this.

What looks like that looks for all the world like a resistor um network. but obviously it's not. It's some sort of uh, hybrid. um I would assume some sort of hybrid semiconductor.

Maybe we could if anyone's got any data on that is that is that a date code like 83? uh, 10th month? I guess Um, 83 perhaps? Uh. Anyway, we've got ourselves a trim pot down here which has been sealed that obviously sets the uh blinking rate on this thing. A couple of large caps we've got uh, is that a uh, Is that some sort of uh diode? I Assume that's some sort of um, either Xena or uh, uh, regular diode? Don't know. and these look like a big ass resistors.

I'm assuming I can get in there and measure those there. Any values on those not really. It's like K12 as the type I guess and so I don't know. They're sort of like a metal can with uh, end caps on them.

Um. and then we've got ourselves transistor over here. By the looks of it, it's a K181 148. Maybe we can look that or is that a KT that could be a KT 8148 and uh, well.

there you go. A couple of other resistors down there and that's our blinker circuit. Yeah, I Reckon there's some sort of hybrid module or something I Just based on the sheer number of um, uh pins on there. and uh, I don't know.

They're certainly doing something. some sort of, well, you know, they're not like going to be a um IC or anything like that. It's not going to be like it'll just be like a transistor array or something like that would be my guess. I don't know.

Um, this stuff is certainly very ancient. We' got ourselves a third contact up there, so it shorts out those two and then it jumps up to the so. it's a um single pole, double throw and then that one comes down to oh, where where does it come down to? Actually somewhere in there can't see it. Anyway, there's our coil wire going down in there.

It's got like a bit of heat shrink tubing coming over. It's coming from this, uh, sort of ceramic network over here. Then it's just being held in place there and the other winding is also down the bottom with some heat shrink tubing and that one's connected over to one of the contacts. Um, there you go.

And by the way, you Yanks may not uh, have heard that term before. blink. Um, they called that here and obviously in uh France I guess these are called blinkers in the US I think they're called the indicator light or you know, the uh, turn signal or something like that. Yeah, here we call them blinkers.

It's like ah, turn on your Blinky mug. Anyway, um yeah, like um I thought these were um I don't know. my car electronics but I was under the impression that these things were, um, typically, uh, thermal, uh based. uh things where you know you, uh, turn them on and they short out and they heat up and then they switch off and then you know it's sort of a mechanical um action.

But this one is, uh, certainly electronic. I mean it appears to have some sort of, um, you know, some sort of transistor or control array in there. It's actually fairly complicated if it's just a blinker module. I mean I gee yeah.

I don't know. Please anyone. I could attempt to reverse engineer it, but that'll take me forever. Um, need to get on to other mail bag itens.

But anyway, if you got info on that, um, then please put it in the comments cuz that is terribly interesting I do like that even the pinouts. um, so I can at least uh Power it up and give it a go. And here you go. Here's this iscra, um, triple one that this, uh, hybrid module is out of and uh, there it is.

Big, huge clunking, uh desktop calculator we're talking 1972 Good Year 72 Um, 12 Nixie tubes Plus sign one memory register fixing coma 220 volts Ac and uh, I think yeah, look at that. Let's have a look at that. We can see all those cards plugged in there. There we go.

Yep, that's the card. All right. There's there's the Nixie tubes. Look at that.

all the cable in running through it. Classic 1972 vintage. Um Soviet Iscra 111 Electronic calculator. Awesome! Thanks Silv.

that's great. Next up we have one from Richard J Stanton Thank you very much Rich wonder what that symbol is? Is that your family crest? or is that your company, uh, symbol or whatever he's from Oceanside California 92054 can't say I've been to Oceanside California So uh, thank you very much. Rich I Won't call you dick T-shirt Awesome! A ceramic mug. Oh I've got a I've got a mug even though I Don't drink, drink coffee.

great. Great for holding uh, screwdrivers and stuff in a flashlight. Wooo! I Always like flashlights and supplies H Let's check it out. T-shirt Fantastic! I'm going to love this all right.

I've had this one for a while too. sorry about that. this one's from May Oh know May 22nd that's not too long. that's not too long at all.

All right. Beautiful. Oh, we have a letter. We should read the letter first.

That's a polite thing to do, is it not? I Hope your address is not on. Yeah, your address is on here. Don't put your address on your letter otherwise. I got to to edit this thing.

All right See: I Got to black out the address up there anyway. his emails there for everyone to email him. If you want to put your email on there probably shouldn't cover up emails. What are you going to do? Get spam? Get the spammers to watch my blog just in case they can Harvest a couple of emails from it Dear Dave I Really enjoy your Eev blog I Was at the Uh 2013 Delmare Electronic Show In Delmare California Never heard of Delmare.

There you go. I Didn't know there was an electronic show there. Picked up some good stuff I Thought you might enjoy. Excellent is this? I assume it's like a trade industry trade show kind of thing.

Um, If so, um, please tell us what's there. I Also enclos two sample advertising packages from a company that my friend. Bob Green owns Power Pack. All right, Power Pack develops customers, packaging, manufactures the packaging equipment, and provides Packaging materials.

Additionally, I include a pen from another friend Adrian Pelus good day Adrian Who owns a Squ Technologies Good name a Square Technologies assists inventors to go from ideas to Market Oh I hope it doesn't include patents. Oh anyway, check them out. Thank you very much. Rich Awesome! Let's check out the stuff.

All right. it's nicely packed. Look at that tissue paper. Oh, it's all happening.

Well done. Oh there there there's my coffee mug. There's my coffee mug. Here we go even though I don't drink coffee.

oh made in China Norwood What's Norwood No idea Cons: conis conis Electronics Manufacturing Services There you go. Fantastic! I Love coffee mugs. great for putting screwdrivers in I'm telling you Fantastic! Look at this. Bobby Desler All right and more stuff.

Power Pack Blist official Cam Shell Opener What sort of Cam Shell Cam shell SE The Deal: A rotary sealer quality cam shells. There you go. I Guess if you're into your packaging solution then fantastic. Um yeah.

oh no. look look these bloody annoying. um uh. sealed.

I Don't know what you call this type of packaging I God the Name Escapes me at the moment. but they're bloody annoying. This is the most frustrating thing on the planet. I Swear all this like this heat sealed around the outside.

You can't possibly open these things without a bloody pair of scissors. What Whoever invented these should be hung, drawn and quarted. They really should be uh, disposed of medieval style because these things are just awful hate stuff that's packaged in this garbage. Absolute garbage.

Oh, we have a nice pad. there we go and uh. Tada and it's a cam shell. official Cam shell opener for open? Oh right.

oh look at that. There we go. we have ourselves. Blade all right? Ah right.

Okay I get it. it's like a Stanley knife. what we would call a Stanley knife here. So you whip it like that and it's opening your packages.

Neat head of the pack. Look at that. Brilliant. Reminds me of the old uh um sorry for Australians will know exactly what I'm talking about not being insulted the famous Dicksmith Dick Head and uh, I assume that's his mate Bob Green Who founded that in 1984? Is it who owns? Uh Power Pack Industries But there you go, Head of the pack.

Lovely. Do. It just occurred to me that they're actually advertising the cam shell packageing. This is what they called clam shells and uh, but but of course you can get clam shells I Think don't quote me being the packaging specialist that I am not.

um, that you can get ones that just you know, uh, close and they're just like, you know, just have a hook or sealed at one end or something and you know, not just completely sealed around the outside like that. Annoying. Anyway, that's a clamshell. This is a blister card pack.

These are. It reminds me of the old days, you know. Go down to Tandy SL Radio or Rat Shack electronics and you picked up your two resistors in your blister card pack. These can be annoying sometimes because you peel them off like this and somebody needs to invent one that you know.

You always try and get there at the right angle and sort of dig it in just so that it doesn't stick on like that. cuz that's ridiculous. These things are so annoying. Not quite not nearly as annoying as the cam shells, but anyway, they're not bad at all.

But there you go. That's a Bob's business card. Good day. Bob Look at this.

Dave L Jones Personalized pen fantastic from a squar. Well, their advertising his mate from a squar. Technologies Art Manufacturing Services There you go. They're uh, as Squared Tech.com and I've got my own personalized pen davil Jones got a nice rubber grip? don't mind that at all.

It's quite ergonomic. Very nice twist. Wonder what? uh oh there we? DPSS Lasers Ink: So they've obviously, uh, laser engraved that might whack my macro lens on. Get a closeup and there it is.

Check that out. I Guess that uh yeah, it looks I guess the Laser's gone along there and uh, it looks like they put this red coating on the outside and then the lasers able to I don't know what that red coating is actually and but uh, clearly that's what they burn off with the uh laser. It's just some sort of, you know, lacquer or uh, something like that. Perhaps if anyone knows that technology of that uh coding, please let us know.

and I you know you wouldn't need much laser power at all to uh, zap that off? I'm sure now. I'm just wondering when they engrave this because it's a curved surface I wonder if like either they have the pen in a jig which then rotates under the laser like that and it's just maybe a fixed axis like that or whether or not the a the laser actually sort of, you know goes around on a slight angle or whether or not it just sits there like that and the laser just goes XY and just, uh, maybe compensates for. Oh I Don't even know if it needs to compensate for the curved angle, the curved surface that it's engraving I Assume it would have to compensate a little bit, otherwise everything would, uh, turn out a little bit. uh, a bit curved.

but uh, there you go. If anyone knows if anyone's seen those uh, you know, laser engraving machines I Assume that they don't do anything complex I Think you just compensate for that in software. It's just like a got an XY uh laser just like a regular laser engraver. I Don't think that have anything special going on there and there's nothing like a trade show.

Swag is there. You know you go to these trade shows and there's just all sorts of stuff on offer. Digi Key: Hello Digi Key: They're not sending the uh, their printed catalog in big bags anymore, so uh, they're in my good books made in China Why not made in the US You're proud American Company Digi Key: Why the hell you ordering this sort of stuff? What is this? Anyway, it's like a holder. What is it for business cards or something? I Don't know.

Some sort of stand might come in useful for something though. More swag. We're not done yet. That's a pretty solid box, don't what? bloody hell, it's a pen.

Bonanza Folks look at this. How many pens did he steal from the blood? Every single stand. Unbelievable. Well, I'm never going to be short of pens again.

This is awesome because I'm always running out of bloody pens no matter how many you get. They're just never around when you need them. and that one's got a ball on top. What the? Oh roet folks? I Just broke the ball off.

We have a globe on the top. What a wank who which company is responsible? Oh it's just got some pins there. Oh there we go. this.

Just like a watch pin. It's just like a watch pin. Which company is responsible for this? Abomination Really Name and shame. Name and shame we secure IP And intellectual property destruction and E-Waste Recycling Company No.

I'm sorry that's a fail. Oh, hidden in amongst the pens, look got a syringe. Beautiful! PCB Libraries New Dimensions for Eda Hey there you go like steroids for your CAD tool PCB Libraries.com no I was completely sucking in folks I Thought this is actually very cute I Like it. It's actually a pen.

I Didn't notice it through the bag there. That's great I Love it. Syringe pen. Never seen that before.

Brilliant. Well done. That's a thumbs up folks. You want to see the difference between a pass and a fail.

There it is right there. that's just pathetic. This one that's cute I Like it and let's see what Digi key have been able to buy from China Yes, it's a pen you rotate, it comes out. but it's also a crappy little pathetic torch.

Look at. Look at that. Oh no. look.

it's got the DigiTech Lo it's got the digi key logo. Look there you go. Look at that. Oh what a complete wank.

There you go. So we've gone from. Where is it? Kind of cool, right? two. Where is it? Oh I Tossed it Complete fail two.

Complete wank. Digi Key Oh, come on fellas, give me a break and check this out. I've zoomed it right out on my camera I've turned the lights off I'm looking up on the wall there and I can project this rubbish up onto my wall as big as I like. Look at that.

That's pure wank. Digi Key components. Ah, unbelievable. I could do like and puppetry.

How about this one, huh? Can you read that? And if you're wondering how they do that, Nothing special. All they've got is a lens up there. There's the ins insert with a little wanky uh Digi key logo down in there and uh, just an LED embedded a large LED one of those 10 mm ones or something embedded in there. Oh look at this.

They're trying to outdo each other. This one had this company. who are they medical device packaging Transe B.com and ITW company wanted the pack more packaging uh stuff. syringe.

Oh no. Trans Tech Are the syringe printers right? They print on syringes. There you go, but they actually have real liquid in there. Ah, they've one up.

the other mob brilliant r car. Look at this as if anyone's going to hang this thing from their keychain. You're got to be kidding me. That's just garbage.

Quality. Absolute oh my oh my. God that is that is pathetic. That is pathetic.

That's almost as if it's like a bulb. You know it's almost like bul like rather than LED I'm garbage. What else we got? Pacific Transformer oh what? what do they got? Oh they're um, something like another. more packaging openers.

There you go. Pacific Transformer that's got a blade in there and uh, that's for whipping something open. Not sure what? Sure people are screaming at me I don't know. whatever they are.

got a lot of them. Advanced Test equipment rentals they have. they went the spirit level option. Oh come on, nobody wants a little cheap ass and with a measuring tape nobody's going to carry around a little crap ass tape like that.

At least it does does have Imperial and Metric So there you go H bit of a bonus there, but no, they're so poor quality they really are. You know if you're going to give something away, you know I used to trade show they used to give away like a you know genuine maglock. You know I mean really good quality stuff for a Swiss army knife or something like that And now we've got strips of what? Why? what am I going to do with that? What would anyone do with that? I'll give it to Sean Now this has wank written all over it, folks. What the hell is this? This is like swag.

mailbag swag. That's what it's all about here. What the hell does this thing do? Does it light up? Prime Line: China Everything comes from from bloody. CH oh what are we? Oh, they're markers.

There you go, they sorry, they're um. highlighters. There you go. Nobody's going to use that though.

I mean you just want your proper highlighters? The seal on that's probably crap anyway. and oh, I don't know. Oh, what is this Bell.com At least we have a clown. No clowns can't have clowns genuine.

3M Adhesive has sprung for the high-end option there. What else have we got? Oh, there we go. magnifying glass that's at least relatively useful. Lots of distortion on that.

Pretty crusty, but jeez, at least you can make use of that. Fry some an or something like that perhaps. And then we have a seethrough. a ruler with a see-through window.

No, we got a couple of more rulers. Rulers are popular. not as good as what I was giving out at the trade show. Look at this.

This is how you do trade show swag. EV blog ruler. Look, it's got everything you could possibly want on there. All your conversions for your Smds and all sorts of stuff.

Fantastic. You can download this from the EV blog website. Actually, you can download the uh Gerba, so that's at least bloody useful. Not the garbage.

Some of the garbage we getting here. Hey, steal ruler. That's not bad T 50th of an inch. That's all right.

It's got metric and Imperial that's not bad. See, that's doable except for the fact that's not an end ruler. see I made this as an end ruler so you can use it as a depth ruler as well so you can't do that on this one. Bit of a fail.

But anyway, is that made in USA Ruler but that's not bad I Reckon that's probably the winner out of the swag. We're almost done. There's another one of those rulers with the seethrough magnifying thing. I Mean they're just not that great really? Ah, don't know.

T-shirt Brilliant. What have I got? What have I got here? we go. let's have a look. have to zoom out on this one.

is's it from? Ah, it's the surfing surfing ape. Awesome! There we go. 2013 Delmare Electronics and Design show. That's pretty cool.

Look at that that awesome in his bodies. And his thongs there. No, they're not flipflops, they're bloody thongs. And uh, there you go.

There's the companies who sponsored it. Eh, who cares. But anyway, there you go. That's the Delma Electronics Design Show.

Thank you very much. Rich That's great. Good look at some swag there. I Love it.

Oh, that's sorry that's on the back. I Just realized what's on the front. Ah, there we go. a That's not nearly as good as the back man.

Anyway, you can't How can you beat a surfing ape? It's brilliant. Next up is a big bright yellow one. I Like it. don't get these too often Destin Nario I don't know.

What is that? uh I don't know. Is that an Italian I Guess destination That's Italian for Destination and it's from Gabrielle Gazi Gabrielle Gazi from Italy from Sunuso I guess s in Italy Thank you very much and let's check it out. Oh holy crap. Oh I could use the oh excellent.

Excellent These pin jumpers. Fantastic! Thank you very much. They will come in very handy. I Was about to actually order a uh bunch of these.

They're very handy for plugging in your uh, breadboard of course. So uh, fantastic. And what else we've got in here? It's almost. It's quite what.

And we have a letter Gabrielle's from G Tronics.com Started using it for some preliminary testing. I Realized that the available free space was quite small. Yeah, it's pretty. Yeah, you don't get much space on there at all.

Soldering D Desoldering was a real pain in the neck for debug. Need a debug head? Yes. So I decided I Need a prototyping board that should be a solders b. Not small, but neither huge of course.

So that's a reasonable size. It's like, you know, bit smaller than A4 Yanks Don't know what I'm talking about with A4 small than letter size. There we go simply to be um, simply to be power supplied Simple to power I Think he means debuggable without the need of a dedicated header. uh compatible with the most popular microchip programmers and debuggers.

Took a look at the market couldn't find. As you do, you do your roll your own. fantastic and I decided to develop my own board and here is the pick: Proto board. You can power the board from a free USB port.

Excellent! Um I wonder if it's got batteries on board? I guess not. Uh, it does not need soldering to set up a test environment. It's solderless and provider with set breadboarding cables provided. Uh, you get a 16f 87 with it.

Uh, lets you choose the pick uh Vdd voltage. very nice. I like that works with Pit 2 uh Pit 3 ICD and all the microchip programmers. It works with any of the 16 F40 pin dips.

um pin out compatible with the 887. Um, it is reasonably small. It's provided with a small sped of spare. small set of spare devices.

Excellent. Has a few onboard devices potentiometer, land push button, all the usual stuff. Found it useful since I can use it laptop and I'm program and Tes in excellent. For additional info, take a look at Gtronic Doet good on you Gabrielle Let's have a look here we go.

Here's some easy to open packaging, Huh? huh? Look at that easy I Love it. That's what you want Amazon Like frustration free packaging Pick Proto board Quick start manual. Oh look at that. Hey look at that.

It just sits in the middle of the board like that. Neat. I Like it A and there's lots of documentation goodness here of how to do all the stuff. looks pretty good.

gone to a bit of effort there I Like it I Like good documentation. so there you go. Very nice for a pick beginner and it includes the schematic as well and using the Pi. R Bo Let's take a look at the hardware.

take a look. Here we go. Tada There it is. it's it.

Literally is a pick micro with two big bread boards surrounding it and that is bloody useful. Let me tell you, I really like that. hence that's what all these uh jumpers are for of course. so you can just whack those in there like that standard machine pinned machine pin header in there and you can whack those directly on the breadboard.

Very, very nice. I Like that. Very useful. What's under here? Oh, that's our adjustment for the big ass pot.

Check out the size of that big ass pot. It's an absolute monster. and of course you just put headers around it. um like that1 in headers and oh, there we go.

Ah right. Oh, so it didn't break off right in packaging. Very nice, All right. and the four feet haven't been uh supplied.

I guess to save Um packaging space once again, so that's very clever. I Like that. very minimal. Um, there's the Um Ice interface.

there's USB interface down there and we've got some bypass and power stuff so you can power um from the USB or a plug pack. Very. there we go. There, we go.

Let's have a look at the this is really quite. Neat Pick Proto Board from Gtronic doet I Really like it and uh, check out the heat sink here on these Regulators Check it out there we go. We' just got got some uh, um, so 223 uh voltage Regulators there and uh, just big long ass strips like that I'm not sure how thermally efficient is when it's uh, that long and skinny like that, but hey, you know it's not bad at all. and it's got the key underneath for the various power options if using USB blah blah blah blah blah.

That is a really neat little board, but tell plus the price son and I just checked and it's uh, 4950. Uh, so just under 50 plus postage without the Uh Pck kit. although he also does sell the pick kit as well to go with it if you don't have any of that, so that's really quite neat. Rather than just have a big Uh Proto ball that tries to have everything, lead, displays, and the whole you know, uh LCDs and the whole um shebang, then um, no, it's just the big ass pick down in there and then build whatever you want on there.

Quite neat. I Like that. Check it out if you're in the market for getting into Pcks, so thank you very much. Gabrielle And that's all we got time for for today's mailbag because I better get into doing a bloody tear down.

It never ends here on the evev blog. Relentless pressure to produce videos anyway. Um, I will no doubt tear down that multimeter right now. So I'm not sure which of these videos will come from first, but if you want to discuss it, jump on over to the EV blog for and if you like mailbag.

Monday Please give it a big thumbs up and I'll continue to do them as long as people keep sending me stuff anyway. Catch you next time. Wait, hang on. No, we're not done yet.

We' still got one from Michael Nash because I haven't opened this in ever. There was like April 12th or something and I feel really bad and it's a metal detector here we go. Quick. come on, it's in whacked in some box and quick quick quick, Come on, come on.

Ah 12th of April sorry Mike his EV blog Forum name is X-Runner yes I know Mike from The Forum hello from Texas Everything big GRE in Texas enjoy your videos and Forum so I Thought you might like to take a look at this device I got it from the local discount Chinese Import Tool dealer in town please open her up and tell us how the circuit does its intended job Beauty All right here we go. Metal Detector That's uh oh. that's right. I think he posted a Puzzler about what this thing actually did on the Forum and um, handheld metal detector.

Here we go look at this Tada press I guess it's Not Mere metal no sensitivity I don't know we're GNA have to actually. um yeah, it's got some battery. Oh no, there we go. it's quite doesn't work.

Do plug it in. This is terribly exciting. Riveting video here folks on the EV blog Stalling Batteries should edit this out. but I don't where Andy Approved safety goggles when replacing battery.

Where's safety goggles when replacing the battery? Highly dangerous these 12 that's not even a bloody alkaline. Is it like carbon zinc or some crap? Oh man. read manual before use. No thanks.

Keep dry. Yeah well. okay I'm not going to use an underwater keep it of reach of children I Don't know San might like it. Oh Oh goes beep, goes beep and it has a light.

it is detecting the presence of metal that might make an interesting D down there you go H feels really cheap I mean oh man, it's just like an off-the-shelf uh, the cheapers off the shelf. Uh, two-part case you can get just held together with a couple of screws. Really, really, quite really. quite dodgy.

How much was it? About 10 bucks or something? I don't know something like that. but yeah anyway, that will make an interesting tear down so we'll wait for that next time. See you.
