Hi welcome to the ever popular mailbag segment. And yes, we have a helper today cuz it is mailbag. Monday It is actually Monday here and uh, it is also Daddy Daycare Monday. So we have a Helper and yes, look, we've reached the one San limit.

well past the one San limit of mailbag items. It's ridiculous. So are we going to open the mail? Seen? Where are the packages? you want to open them? Yeah, you want to open them. Yeah, we'll open a few.

All right. Where's your screwdriver? Where's your screwdriver? Quick. Get your screwdriver ready. All right, we're ready to go.

It's mailbag time. Let's have a look at some postcards first. Uh, this time it's a postcard from my country. The Malaysian one is from where I'm taking my electronics uh, engineering course, majoring in telecommunication.

Hope you like it from Abdulaziz say just touch the screen. Abdulaziz s aiz good on you a is from Bahrain Awesome! Thank you very much. Let's I have no idea what that stamp is H I don't know. can anyone read that and tell us what that is? got? no idea I assume that's some dude important like I don't know the king or something and what do we got on? Oh look Bahrain there we go.

Beautiful! Love it. Great shot that what they get that from the boat or are they on the other side of the uh Lake SL Lake I guess is an artificial lake or is it a river? It looks like an artificial lake or something like that. It's uh really very nice. Thank you very much Aiz! I think we've got a package from Aiz as well so we'll have to check that out.

And next up we've got Chicago Hi to all my viewers in Chicago I've never been to Chicago always wanted to go so um, get there one day I'm sure and it is from uh well from Temo Chicago and uh Trump Tower used to be Sears Tower There you go and uh Chicago skyline is the world's tallest and easily ranks among its most magnificent. It boasts three of America's five tallest buildings. The Willis Tower formally known as the SE Tower stands 1,451 ft tall. Ah, meters.

come on you. Yanks And it's the tallest building in the United States of America. Thank you very much. That is awesome! Oh San where's the screwdriver? Yeah, you got the screwdriver? You ready to go? He's ready to go folks.

so thank you very much. Here he is, he's going to attack it. And first up, we have a package which really, oh you dropped it. There you go.

Oh oh, you ready? Yeah. going to open it all right. First up, uh, we got a package from Pete uh Mitchell on the Forum he's a fellow Aussie and he, uh, this wasn't going to be a mailbag GU him. but thanks Pete he sent in a uh, a video card um to do some video uh tests and stuff on a radian fairly high-end radian card.

Oh can you open it? You've opened most of it. He's already had a crack at it folks. Oh, look there we go and uh, something else. I Don't I Think it's some sort of cooling device.

It is a bloody big package. That's for sure you're ready open. Oh wow, wow. What's in there? Look dude.
Wow. What's that? Okay, there's lots of bits in here. Oh, that's heavy. What do we got? This could take take a while.

folks. you know children and animals, that sort of thing. Oh huge big monster heat sink bracket. Look at that man.

that is, uh. enormous. It's an FC 5870 Isus Version 2. Oh, it's a liquid.

Uh yeah. the the liquid goes through the channels in there I Can see the O-ring uh seals and this is the heat sink plate and this is where you, uh, these are the port. I Don't want to touch the back. these are the ports.

Looks like huh? Doesn't look like they go anywhere. but yeah. anyway, it looks like that's the port. Oh there's the heat sink pad for the CPU and this is a pretty I Mean that's a that's a big chunk of.

um. thanks. Oh F San Found a tape measure. He loves tape measures folks.

Show them your tape measure Tape measure. Yeah, they're pretty cool. Oh, you like measuring? You want to measure the package? See how big it is? Can you measure it? Oh good boy, yeah, how big is it? Wow, it's exciting. Isn't it all Right now? we'll dig in to the rest of it here.

and Motorola Zoom 32 gig memory? huh? Oh, it's a that must be no Motorola A Motorola Zoom Oh is a tablet really? No, surely not. Surely he's uh oh, he's found the liquid. Oh man, jeez, this is this is ridiculous. Thanks Pete What a care package! Unbelievable and um, sorry folks Something's Happened to my lapel mic.

so um, it's uh. the audio is probably going to go in and out. in and out on this one. so sorry in advance.

So he hasn't sent me a tablet. It's obviously the video card. Yep, oh yeah, jeez, that's that's heavy. There's a lot of weight in that video card.

That's crazy. It's very exciting, isn't it? SE Yeah yeah. Pizza Top bloke, isn't he? He sent us this. Yeah, and there we go.

Tada it is. It's made in China Of course it is. but uh, this is the um Zeus um I forget the exact number the uh oh God no I have to put in later. but um, it's it's not a recent one.

I Think it's a year or two old, but it apparently is a topnotch, kickass um. video card. So oh wow you. He's found a radiator.

folks. Hang on. Hold it. hold it.

He found a radiator. It's exciting. Look the size of that Bloody radiator. That is ridiculous.

Unbelievable. What's the a cooling system is this? Jeez. Cool down the freaking Satin 5 booster with this thing. It's ridiculous.

Crazy. All right. What do we got here? We got something Sony Experia No, it's empty I Think it's empty San is it empty I think it might be empty I can't feel anything inside I think it's empty I Think it's just padding. Yeah, it's just padding dude.

All right and better. hurry it up. And we got all all the tube in for this cooling. Wow, it's exciting.

There's a pump. There we go. We got a a swift Tech pump. so all you cooling fishon probably know all about that.
Oh he's trying to put it together. Oh there we go. He's pretty close a it's difficult isn't it? Yeah, that's pretty good. Good work dude.

And we got more liquid. Check it out. e Coolant Clear e coolant do not mix with other liquids. Okay I assume that's just like a glycol, uh, mix or something.

um, like in your car. So no. oh there we go. We have some screws and things.

Don't lose that. Wow, this is a mess. An absolute mess and a whole bunch of crusty fans. noctur fans.

They've all still got all the gunk all over them and the fan grills and a whole bunch of the uh, clamps and everything else. For the oh, you're playing with the fan, it's pretty good. Wow, it's spins. Do you like that? Yeah, yeah.

all right. cool. Um, thank you very much. Pete that's awesome.

There we go. It's a 58, uh, 70 Radon. It's got uh one gig of uh DDR memory V2 something like that? so yeah, um 5870. It's a little bit old, but apparently uh, um, Pete tells me that it's a really good performer, so be awesome to try it out.

Love the black uh, solder mask on this matte black solder mask. actually. I'm not a huge fan of it, but it's just quite, uh, rare to see it. uh, really.

maybe not in video cards or something like that. but yeah, I don't see Matt Black solder Mas that often if you're going for black. if you're going for black, Go Matte folks. don't get the uh gloss one.

It's just absolute garbage. And Alum actually went for the uh gloss black solder mask on all their products and H I just I just don't like it. it's just h no I much prefer the uh matte black like that the you get, uh, nicer, uh, you know you don't get a huge uh, shine on it. and also I think you get better contrast on the silk screen as well.

And here is Z's uh package complete with tons of stamps again with uh, that important dude again or a couple of important dudes on there thank you Sean that's very good. awesome and uh, what do we got up there? Lots of colorful stuff, some beautiful coloring that oh no, it's no touching the lens. All right Kingdom of Bahrain So yeah, that's got to be the Bahrain King obviously so thank you very much is is doesn't say what it is so let's just, uh, whip it open here. Oh yeah, what's in there? Oh, there's another postcard there we go.

Oh thanks I Saw this tool at the hardware and popped. um and you popped up into my head. That's scary. thanks as is.

Oh pearls, There you go. What? What do you got? Sean look what's in there? What's in there? Oh look, it's a folding utility knife. a a Oh yeah. good.

good closeup. Oh yeah. very good. Thank you.

You want to open it? Can you open? Oh, it's a bit tough isn't it? But look see, they fold out. look it's a screwdriver. Is that cool? We've already opened that package. it's empty.
Yeah yeah. is that good. Like it. And next up we have an Aussie it's Andrew Donis Thank you very much.

he's from Balin in Bine in Victoria I don't think I've been to Bine in Victoria so uh, thank you very much Andrew I Have no idea what this is doesn't say so let's crack it open ready. let's open it up. Sean What's inside? What's inside? do you think H Oh, you don't know. All right, let's have a look.

What is it? Oh foam. Oh, choose from eight characters. Fatal Fury 2 Why do we have a Fatal Fury 2. um I don't even know what that is Gamers you'd know.

oh this. Oh look Wow. Oh, it's a gammer board look. Fatal Fury 2 Jammer board beautiful and um I um Well, my arcade machine has a uh Jammer um compatible uh board in it.

So maybe if I plug the thing in? Yeah, over there the arcade machine. That's right. Yeah, Fatal Fury, It's a game. Where's the arcade machine? Yeah, it's over there.

That's right. Um, awesome. So this is I've never actually seen, um, the package for this before, but there you go. It's a cartridge uh, based system like that.

and the Fatal Fury 2 cartridge plugs into that. and yeah, more packages. No. and let's see if we can get this off.

There we go. Who? Here we go. This is pretty. Uh, this is pretty recent.

Check it out out. We' got a Sheber I'm not sure what that, what have we got? Uh, where's the processor? Not sure. We got some huge um quite a flat pack Lsis here. thanks San screwdriver? yeah, made in Japan it's an SNK it's a Neo Mvh I'm sure all the uh, thank you Sean yeah yeah I'm sure all the arcade fans know all about this.

Got some dip switch settings on the side and um, there's the Jammer connector down there. there's my bare feet and uh thank you Sean yeah and uh I do have a Jammer compatible card in my um arcade machine I believe Um so I'm not sure if I can just uh, plug it in and have it. uh, go though. I'm not sure what the actual uh deal is there, but uh I'll have to have a look I won't do that.

Uh, right now I don't want to take the arcade machine apart with uh Sean here cuz all he wants to do is play it, don't you dude? yeah Sean just turn the camera on thanks San it looks like um serial number is no San don't push, don't you just push the record button again? Um, the serial number. We're looking at um 575 there so they haven't made uh, all that many of them or I've got a very, uh, early one. thank you San you love putting things in front of the lens. We don't have the macro lens on though.

yeah and um, it looks like 93 uh date code on here. so this is actually a um, you know, um, early to mid 90s vintage. uh SNK yeah more packages. Jammer board cool and inside the cartridge down in there.

we got a couple of huge ROMs there and uh, not sure uh if they're mask ROMs or something I'd have to, uh, check the number on that. but uh, and there's two boards in there because there's a there's a bottom board down in there with its own uh, bunch of chips on. I'm not sure why they have to use uh jeel slots like that if anyone knows the history behind that. I'm sure it's on the Wikipedia page.
You could look it up now. check these out. At first glance, I thought that these were capacitors, but they're not. It looks like they're little um, thank you San little RFI um beads there.

Hence the you know, they've probably just got a wire coming up like that and looks like they're in a plastic uh package. So you know, like they probably got. you know, Ferite there and Ferite there and just encapsulated or something like that encapsulated in a plastic package like that I haven't uh, haven't seen those before. It's rather unusual and uh, these look like, um, standard, uh, resistor arrays but they've labeled in CR I Don't know why they've uh, done that, but they just look like a pull up resistor arrays and it looks like these are custom As6 from um SNK Corp They've got two of them and the other one over here is the uh Neo B1 chipset.

So there you go. Fully custom uh, As6 on these. uh Japanese um SNK Neo Arcade boards I'm sure, um, anyone with all the details on those can pass it through and I'm guessing without uh uh knowing this or uh, looking up Google The Ym2610 there is. probably given that it's Yamaha it's probably some sort of chip I would be guessing and another custom chip, it's a Neo ZM C2 once again, 94.

uh vintage. So this board is at least uh, manufactured in 1994 and there's our main processor Tada Motorola 68,000 No surprises on there at all. more. Um, SNK Corp Neo e0 and the Neo F0 chipset custom everywhere.

And it's interesting to note that there are really, essentially no bypass Caps or um, passives on this uh top board. Really? There on the bottom of the board. There's not that many of them. you know, there's a few.

There's a bunch of resistors down here, and uh, stuff like that and the odd bypass uh cap scattered around the board and they've gone for a double-sided load. I Mean, if you're doing a high volume uh product, you wouldn't uh, do that. Of course you'd try and put everything on the top so you didn't have to do a double-sided uh load. but these things aren't manufactured in huge volumes.

You saw the serial number on this very low. Me: we're only talking. you know, thousands or tens of thousands of machines tops. And we have a letter from Andrew Hi, Dave my brother Luke and I big fans of your YouTube channel I Blame you for my acquisition of Two Fluke multimeters.

Oops, Sorry, at least you got the A got Beauties 875 and 27 of which I don't have a heap of need, but still have plastic film on the LCD display. That's cool. You don't need a reason to own multimeters and lots of them. Sean's over there playing with the fluke.

Now there he is. Is that fun? Sean Show. Show us the fluke multimeter. Yeah, you like the fluke multimeter.
You remember you were in a video with the fluke multimedia. You drop tested it. You're trying to put the screwdriver in the jack. Do you think that's where a screwdriver goes? You do Okay, Please find the included Neo Geo Mvs Multi System.

There we go. Piece of Be along with Game Cartri. It was an interesting bit of hardware for its time. The Mvs and the near ident iCal Home version: AES Oh the Advan I Don't think I've ever heard of the Um AES uh, '90s vintage.

If you pull out the rather large cartridge and shake it, you notice it rattles due to the two disconnected Pcbs. Ah, I didn't do that. Perhaps best of all, Mvs oh San's trying to hop down Off the Bench Oh, there we go, dude. All right.

Perhaps best of all, the Mvs doesn't work. Cartridge should work. Ah, if you're only person who is honestly disappointed when something does work. so I Hope you like this board.

Hope you find time to do a fault finding repair video on this board. It uses a near standard Jammer Um I use an old C with scar disconnect blah blah blah heap of information on the web. Yeah, I'm sure there are um these uh Retro Gaming communities are um, big on sharing? um stuff. There's tons of info out there and uh, he dabbles in some very basic Arduino Raspberry p quadcopter stuff.

Here are some photos there. we go check out Andrew's photos at his flicker account. Keep producing awesome content day I Will indeed thank you very much Andrew and Luke Next one up comes from Arachnid Labs Love it! Cool logo there with a little uh Beaker in there from the UK the Old Dart from London Awesome. Uh, it doesn't say who was from electronic parts.

25 bucks on the customers for. So let's rip it open and we have a letter. AR Raknet. Hey, we have a kit.

We have a kit folks. It's the the Epic reload version 1.0 kit from Arachnid Labs through Hole stuff. Open it up! We got some little uh stickers here from Makers of Fine Electronics since 2013. Pretty darn recent all right.

And it's a heat sink. Oh, is it a dummy load? No. Oh yeah, Reload H hence the name I Reckon maybe it's based on my uh, dummy load thing cuz a lot of people are doing that Hi Dave I've been making my own Electronics projects for a while now and I recently started putting together kits for others. My first project is called Reload I Love the name.

it's cool and it's a constant current. DC Dummy Load Active Load inspired in part by your Uh entries on the subject. It's really simple, near indestructible. Yes, that's a challenge, long as you don't go over 30 volts.

Oh well. Jeez, No fun there. And powered by the device under test I Thought you might find it interesting and all useful entries are always fascinating and informative. Thank you very much.

Nick Um, it? How's it powered by? um, the circuit under test? What? If you've got like a low, you know, um, you're only testing like a 1vt, uh, Source or something like that. That's the problem. Um, so yeah. Any, any schematic.
No, there's no schematic for instructions. We have to go to Arachnid Labs.com reload. and isn't it cute? It's absolutely tiny tot and it just mounts directly on the heat sink. Like that? The same series heat sink that uh I use.

They're rather popular from Thurm alloy. um, you know, pretty much a bit of a standard Um heat sink I guess you could call it and uh, there's not much there at all. It's just going to be Ic1 which is just going to be a a uh, a jelly bean Op amp and uh aha, it's used a microchip mCP 62 opamp and uh, what's the transistor? It's a BTS 14 one fed. There we go I love it how they've labeled it.

drain source and uh, what else have we got? There's our uh, here's our shunt resistor. There you go. It's a Dale one good brand 05 Ohms. so 50 milliohms 1% current shunt little three water and uh, that's about all she wrote.

Got a little uh press button um ones down here so you don't need a terminal block so you don't need a screwdriver. Very very nice. cute I Like it. There you go.

If you want to check out the Um schematic for this thing, look it up on Arachnid Lab.com Thank you very much. Nick Johnson from Arachnid Labs and which package should we do next? s again. which one? Yeah, you want that one? Yeah. All right, that's from Thomas Loro yeah sounds French but no it comes from the US W and here we go: Thomas Loro from St Albans in Utah I believe UT is if I know all of my 50 US State uh abbreviations thanks San 31 bucks.

Gez that's a bit pricey but uh, we have t should I spoil it? Yeah, why not? it's on here. We have one Pilot One Pilot One plasma speaker and one calculator I Love calculators. Thank you very much Thomas Luru is that French Luro I think it might be sounds French to me I don't know but I'm you know, just an uncultured Aussie I Don't know these things so let's have a look. let's crack this open.

Sean's bug it off on the other side of the room doing something. Oh W look at this little mini Bonanza there we go. Palm Pilot cradle and uh, who? there's our P pilot? There it is. it's a it's smashed Look at that.

completely gutted that's an M515. I think I always wanted one of those. It was like a couple of models up from one. I had I had the pal pilot three or something and uh we have a note Vermont the Green Mountain State lovely postcards.

Look at this beautiful and Vermont oh look at that. Look at that in Autumn time I'm assuming oh look at the color beautiful that Farmhouse the sun reflecting off that awesome H on does it tell you no, it doesn't tell you that's peachum in Vermont there you go and Lake champ Champlain Lake Champlain There you go. Looks very nice right near the hill and the countryside. and ah lovely printed in Italy printed in Italy folks What? you got to be kidding me US postcard printed in Italy View of Champlain Valley L Champlain Do we look at the other ones? No.
See, it doesn't tell you, it just says I Want some explanations here folks Green Mountain State Population Oh 621 ,760 Motto: Freedom and unity Oh at least it doesn't have any God Rubbish Really? Um so that's great I Love it and the bird is a hermit thrush. There we go. Did you know that is a hermit thrush? And hang on folks I Smell something that smells like cigarette smoke to me Thomas You a smoker? Quit that stuff and we have some color ful handwriting hi Dave I was watching your mailbag videos I wanted to send you some old and one of my own Electronics projects is a plasma speaker. Oh your own design.

Cool. Be careful it is high voltage, runs on 12 volts and it has an audio jack on the side. Um, all right PS YouTube name is Tom Laru and take a look at it and let me know what you think. I am starting out in electronics in that let me know how I am doing.

Thank you and please make a tear down video of the palm and the old calculator and have fun! P Plasma speakers take 12 Vols Let us a back battery to run it to let you know if you can read my handwriting at all. Yes! I can read your handwriting no worries Tom Well I hope the packages are uh well padded. SE Again you having fun there? Yeah, Pretty good huh? Wow. You want that one next? Which one do you want next? That one.

Okay, we'll open that one next. cool. And Tom's included a whole bunch of uh uh, stuff. this is not mine.

Whole bunch of info on plasma speakers. oh lots of YouTube no they Vimeo comments are they Tons of documentation on oh, phasing, oh man, how to phase the Transformer and everything, How to wind it Beautiful. A reliable Pleasant Instructables. Is it? Did he put it on Instructables? There we go.

Is that the circuit beautiful? Or does he say this is not mine? As in this whole thing is not his. There you go. But anyway, here is Tom's homebuilt plasma speaker circuit on Vero board. Beautiful.

There you go. Salvage from a A A TV obviously. Um, that's what it looks like and uh. beautiful.

Home wound, hot snot, got to have hot snot all over it. There we go. Look at that beautiful tin. the tracks on the back.

Easier than sometimes. It's easier and more satisfying than wiring. Doing that. it's very popular technique.

Check it out. We have classic Ti3 calculator. Look at that beautiful uh lead display. One of those bubble uh lead displays on it.

very uh, popular for the time. Really listen to that. Wow, that's like that's built down to a price, folks. it really is.

So how do we? Uh, there we go. Who? 9V There's a 9V battery in there. Does it work? How do you switch it on? Oh there we go. we're on.

Check out the tiny little display on it little bubble display. Can we get pie up there? We go look at that beautiful tiny little display error. No, no, no. Ah, didn't last long.
Hello, No. Maybe the battery's dead or something. No. I Think we've no.

Maybe. yeah, maybe the battery's Cactus don't like it. No there we go. it's just loose.

That's all there we go. Beautiful tiny little display. Oh man. absolutely tiny and you've got to like read it that angle.

if you try and read it straight on, you just can't I mean it's you know it's angled inside there like that. And yeah, those were the days folks. These bubble displays I'm HP used to make these bubble displays I'm not sure if they pioneered them or who actually pioneered them and I'm not sure if TI even use. Maybe they do use a HP bubble display in there.

I've probably still got some somewhere actually in one of my component drawers. Hm. and here's my one: I found it I've got a bunch of these. had them for ever since I was a kid and these are actually my memory was out.

Um, they're not HP ones. They're um, that looks like a national, uh semiconductor. uh Mark there. So um, if anyone uh knows that for sure I can't remember.

it's been. you know it's like 25 years or something since I got these things. They've been sitting in my drawer for like 25 years. got like half a dozen of them ancient.

so uh, if anyone knows the details then, uh, let me know. But let's crack this sucker open now. of course, given the size of the battery compartment, I Suspect it may not have originally had a 9vt battery in there. It may have been retrofitted, but look at that assembled in the United States of America USA USA USA I'm having a real hard time getting this turd open I Thought there might have been some hidden screws under the feet there, but no, there's not.

They just stuck on and it looks like it is a pressfit like a snap fit H case on this thing. but jeez, it's a being a real, it's being a real bastard. Let me tell you. Bloody cheap.

Ti Calculators I Don't know as you can probably tell I'm not a huge fan of TI I've always been a Casio or a HP man myself. All right. I just got a bit medieval on its ass there and uh, I'm able to get Tada look at that. Jeez, there's nothing in it.

Look at that. Hey, that's a weird combination of tinned traces and uh, gold plated. Taiwan it's made yeah, assembled in the USA from made in Taiwan uh. display component.

There you go, but that's it's. got TI on it and uh, interesting. they've just wired it down like that and uh, is that that it? It's just a single chip solution in there. so let's uh oh man, this is really geez.

I mean this is really horrible construction. I mean it's just, you know, compared to a HP one. I'm not sure what vintage um this is, but you know the construction is just. well.

it's just crap. Look at that. I mean you know fck can you do here? We go. Oh 78 There we go.
We have a date code folks. but look that very minimalist design I Love that though. just a single chip TNC 0891 NL Total the custom and it's uh, the 18th week 1978 Ah, brilliant look that and it still works and he's chucked in some pure maple syrup Canadian I Presume maple syrup on pasture? No, it's from Vermont There you go but uh grade A medium Amber pure maple syrup. But really I mean you know, if you want maple syrup, you get it from Canada right? not Vermont Surely.

So what it looks like there with that sort of half tined board. It almost looks as if they've like just somebody's just held the board like this and just dipped it into the solder bath. like to solder the uh chip on there and that was it it. It's really unusual I Don't think I've ever seen a half tinned board like that, especially not a production board.

Very weird. Unfortunately though, you do get AUM thumbs down for two thumbs down for the cigarette smell. I Can smell cigarettes mile away and there's probably nothing I hate worse apart from cats than cigarette smell. Oh, please give that stuff up.

See, the problem is to a nonsmoker like me who can smell one cigarette particle from you know, the other side of the street. Ah, you know this has just got it all over it now. I Got cigarettes smell all over my hands. Time to go wash.

All right I'm about to power up Tom's plasma speaker here. external 12vt Supply Let's see if this puppy dances Tada Look at that beautiful. Check it out. I Love it.

Can we make the Thing dance with some audio now? Perhaps. Woohoo! All right, see if we can move this woohoo apart with my insulated screwdriver there? Tada Look at that. Ah beautiful. Can we make this sucker dance though with some, uh, some audio? I Love that plasma aring.

Look at that. Woohoo! don't know how far apart? That's a fair way. that's a good 10 mm apart. Oh there we go.

No no oh there we go. Came back so it'll go up to a good 50. oh maybe just over 10 mm. We going to there we go.

You have to bring it back to about 5 mm to start it up. but uh, that is fantastic. All right. I'm going to try my Dlet tones on one of my videos here and uh, on my phone.

we're gonna plug it in and uh, see if we can get some audio modulation on this sucker. Okay, hang on SE ready? All right? here we go. I'm going to turn it on. The sound.

Yes folks, that actually works as a reasonable Fidelity speaker. Just the wires there and the plasma arcing on that thing. It's actually not bad at all. and it's actually quite loud.

Um, my volume is, uh, fixed on this camera and it's exactly the same volume that you heard just here. So I'll play it again. and no, that's trust me. that sound is not coming from my phone.

it's coming from the plasma. Fantastic. So let's play that again. I'll turn the volume up.
have some fun. Okay, horrible springing sound in that like you guess it bloody some fantastic new technology that can make it work well. I Smell one person, one hobbyist, one hacker. our one maker can change the world.

    Many years ago I built a plasma speaker using a microwave oven transformer. I did not use a bias arc, it was directly driven with a 100 watt amp. The arcs were about 1-2 inches apart and it was loud, especially around 5 kilohertz.
