I live near Leeds! :-) I want to see a spoof mailbag where you open your actual mail... "And here's a bill from my electric company." "Oh we've had one of these before, it's a piece of junk from the local pizza place" :-)
+James Grimwood I used to live near Leeds too! In between Leeds and York actually, for about 10 years. Loved the place, I may even go back to live there.
+Dean Herbert Home appliances like fridges, washing machines etc usually have a separate earth wire that goes into the frame and needs to inserted into a screw terminal under the socket. Stuff like air conditioners have a proper 3 pin plug that goes into a 3 pin socket... and then power leads for monitors, computers etc have that dangling wire that's meant to attached to the same terminal as the one for washing machines etc or a 3 pin plug but the sockets that are not for air conditioners up on the wall or in the washing machine/fridge bay never have that terminal or are 2 pin so the connector has a plastic insulator.
So I don't mean to complain, although I feel like your videos have been lacking in the content section lately. Your video are almost always either Teardowns, Reviews, or Product Debunking. You haven't done a real "recent" Electronics Project based video since EEVBlog #744. Honestly that's what attracted me to your channel and electronics originally was your project videos, we are engineers and we live for building new and interesting projects. Not that I don't like your other videos, but I think you've lost the best part of your channel by not doing the project videos anymore. Other Electronics VBloggers are doing projects at a much higher ratio than you. Can you please rectify this injustice?
+Cullen Williams Other bloggers channels were not built upon the same diversity of content as mine was. If you haven't noticed, my teardowns and debunkings are incredibly popular, much more popular than tutorial style videos, like by a ratio of 3:1 or more in many instances.
+EEVblog I get this is a business based on views and subscribers. Although maybe sometimes it can be about what you think is cool, interesting, or fun? We all like Debunking shitty products, and opening new products to see what's inside; although I could be completely wrong (and apologize if I am), but I think maybe your core viewers including yourself also loves taking on new projects just for the joy of engineering. In the end this is just one opinion, and you know what's best for the channel. Either way the blog will surely continue to grow, my argument is to simply present this point of view.
+Cullen Williams Iono, I rather enjoy the content he's doing, though I wish he'd dismantle some more dangerous and/or poorly made products found on eBay directly from China. Deathdaptors and the like.
+Cullen Williams Well, since someone else already said it, I might at well say it too. I'm definitely on that boat. What ever happened to fundamental Fridays and such? Just because they're not as popular, doesn't mean that there aren't people interested in seeing them.The power supply design series was incredibly useful. I figured I'd see more EE and less stuff like build quality critiques on something named 'EEVblog'. There used to be, and that's why I subscribed...
if you look you can see an obvious set of 3 colors (gold, silver, copper/bronze which I'm guessing are either multipliers or just a higher value set depending) and then where there are single digits that are (basically) always on have a more off-color then the same color ones in the corresponding row/column depending on what section you are looking at. (Kind of surprised save didn't mention this but did mention the LEDs)
Dave, I like your videos but I would prefer "Turn it on then tear it apart" instead of "Don't turn it on, tear it apart" . It would have been good to see the VFD powered up, not sure about the discoloration due to use , maybe it was purposely coloured. It would have been good to see diagnosis of why the VFD could not have been repaired. same with the Network analyser. Please show the Sony CD player working before killing it or at least try to get it working. P.S. I want to see more repair videos.
I think it's "Dave Jones" initially when he lifted it up, looking at the number of segments, vs comparing the E's etc.... - i'd have to look more into it though
+Jeffery Rowan 419 chevy blaze it, friend!!!1! (sorry if this makes no sense im still hi from last week when my dad went and burnt all the weeds in the backyard, he told me not to leave my window open but i did and toked so much :)) I'm kidding, seriously - but it'd be kinda hilarious if it was weed :P
We still use an Etherscope like that, but I think ours is an Etherscope II but looks very similar except it has a compact flash port for data storage as well as pcmcia. It runs Linux and can do cable testing and you can put in a wifi card as well. It can do impedance testing of twisted pair wiring, wire map, some signal loss, time domain reflectometry for cable length and distance to damaged or shorted cable. When you're running tests the relays are clicking off and on, probably connecting the wires to the FPGA for testing before switching back to that broadcom chip . You can also do network capture for offline analysis.
The different shades on the VFD segments is not only wear but also different coloring. If you have a uv flashlight you might actually see the different emission colors through the glass...
Hi Dave! For the VFD, I don't think they're discolored, so much as different colored phosphors! If you find a picture of one of these displays in action, every section has a different color when it's lit up. You should power-on test it!
It looks like the "code" on the shirt at 23:21 is a binary representation of the number "42". The stripes on the top are 1s and the stripes on the bottom are 0s, giving 00101010, 42 in decimal.
The network analyzer by Fluke. Could it be Jtagged and loaded up with PFsense linux firewall OS? It kinda looks like a full embedded x86 barebone assuming it has 2x 1Gbit LAN ports. Would be pretty sweet. a compact firewall with its own LCD screen build in
+Osmosis Firstly, he already said the SoC is a Intel Xscale. That's ARM, not x86. Secondly, I doubt it has direct access to the Ethernet, or if it did you'd have to write a device driver for it (perhaps even loading something custom on the FPGA to get access). Good luck getting info out of Fluke and/or reverse engineering it. In the end it's just not worth it. Much cheaper and easier to get something from RouterBoard.
The reason why the slash wasn't colored on the front of the shirt is because that's a "button logo" so basically it's just a simple black & white rendition of the logo wrapped in a circle
And as far as the code, I assumed it was binary (there are 8 lines total) assuming bottom row is 0 and top row is 1, you get 00101010 which is decimal 42, or the ascii character * (asterisk)
Great mailbag! I actually pop popcorn for these. I had that original Sony disc player when it first came out. Installed it in my car, Skipped with every tiny bump. But it was the only game in town so it was still real cool.
I have one of those D-50s in really rough shape. I've superglued the plastic window back on and there's dings and scratches everywhere. it got really beat up when it was in storage and Hurricane Sandy came through and destroyed the shed it was sitting in with a bunch of my other stuff. Good to mention in the teardown you do for it that it uses the same analog circuitry to an extent as their first actual retail CD player on a smaller scale... this is why it cost so much when new. Mine still has the 9V battery pack that uses C batteries, and the 9v wart is... someplace.... but I can power it off any of them so long as I make sure it's at least an amp. I got mine for $20 in box at a yard sale back in 2009, looked just like that one. but mine has a datecode of october 1985.
Ok, Dave is this wasn´t a hint: "...i open big things first, they take to much space..." If someone wants go get his/her thing to be opened quickly just make it *BiiG* ;) I repeat myself here again: i *WANT* that shirt, Dave!!
I remember when your knife was sharp. It was a thing of beauty and a joy forever--well, not forever. SHARPEN THE DAMN KNIFE! Then keep sharpening it regularly.
Japanese has electrical system with separate thumb screw terminal for earth connection that is planned to be replaced with American system. Also their gaming place could had blacklight (UV-A) lighting in use, I don't think that red LED emits UV that much.
Yes, I would love to see a teardown of that CD player, that one should have one of those big ass pick up laser. My friends think I'm weird because I like CD players lol, the older the better and more interesting to see them working.
+EEVBlog +Mangy Dog that 'moss' is a plant that survives on extremely low moisture, and can even hibernate when completely dry until it receives a bit of moisture again.
can someone actually explain the difference between a capacitor and a supercap to me? because i know they have a much higher capacity/volume, but i have no idea how they achieve that. Is it a specialt technology or just lower tolarances but the same principle?
Ah, Pachinko halls. Just listen for the godawful din and smell for the overbearing reek of cigarette smoke, probably a good chance you're outside one of them (or within a block...) On Earths/Grounds, Japan is a bit weird like that, their power distribution is very much like the US (which IMO has it's own problems...), but they are very slow on the uptake of three-pin sockets. I gather the flying lead was originally to be put under the screw that holds the cover plate in place (which is connected to the maybe grounded wall box), some of the stuff I saw over there was rather frightening...
That HP-41CX is exactly like the one I have and still use! Just keep a supply of N cell batteries to power it. The HP-15C I have is probably the most ergonomic calculator ever produced, you can operate it very well holding it in your hands with just your thumbs, I guess that's why they command hundreds of dollars on eBay.
Dave, why don't you get a nice big high-res LCD to mount on your wall, so you can tell what the HD video will look like while you're shooting? Or even just a little portable monitor? (e.g. Blackmagic Video Assist for US$500)
About the FPGAs in Ethernet test sets: You want something that can generate packets at line rate (1Gb for e.g.), and receive them, generate CRCs / checksums, and track statistics. That's a LOT to ask of a CPU, much less an embedded processor. FPGA is really the only reasonable choice.
Those orange tantalum caps on the board at 16:23 are imho horrible things. I've seen them litterally catch fire and it staying lit because of the electrolyte bubbling out it when they've failed. Also very hard to replace when that happends because of the total lack of markings. Except for polarity, that point sticking out is the positive lead. Allmost totally ruined a very nice Compaq Concerto vintage computer. I so very much would love to punch the one who invented those crappy things. Never thought watching an old mailbag would get the hairs in my nek to stand up while looking at a random board. EE-Trauma. :)
Hahahahah. See at time 7:43 !!!! Hey dude, take a deep breath of the smell by electronic components. You´re sooo addicted, realy funny to see this. Keep going on with your stuff man. Btw, i like your little tiny knife. ;-)) Best regards.
Should we start calling Tektronix by the name "Time Wave" now? The logo looks like T-lambda to me. UPDATE: Ooops... I'm always writing lambda backward, too... hmmm.
The Sony Disc Player was awesome, shame you didn't get the battery pack/case as well. I remember buying one of the first shipment to arrive in UK, don't remember the date just that I gazumped one ordered but not collected from a high street store in west London by flashing the £300 ish cash wanted for unit including battery case.
Pachinko parlors are the devil! Been to Japan/Tokyo two times and accidentally walked in to them a couple of times. They are SUPER LOUD inside. I wouldn't recommend staying in a pachinko parlor for more than a couple of minutes.
How I miss my HP 41-CV (same as the CX without the RTC). Unfortunately the keys died a horrible death...I had the memory card, equation library and one other card (can't remember). How I miss it. *sigh*
The Radio Shack analog dB meters were ubiquitous back in the day. You couldn't walk into a studio or lab without finding on in a drawer. They actually weren't bad for roughing in. The digital ones were crap though. We ended up purchasing a terrasonde toolbox (?) when our RS analog unit went MIA.
I think you should wear the Crocodile Dundee hat while sayin you're australian and know what you're doin and ripping apart boxes with that machete...Than almost hit yourself with bubble wrap sayin the bubble wrap is dangerous... Love it! :-)
Utica is in what is called 'Upstate New York' as opposed to 'New York City' which is at the extreme southeast corner of New York State. NY state is actually quite large and shares the border with Ontario, Canada at Lake Erie. Utica is directly east of Buffalo, Rochester and Syracuse.
The first one's ground wire in the plug isn't tied to the plug contacts, but to a ground wire in the cable. The idea for these (and also the compatible 100VAC Japanese plugs) is that the wire has a ring/fork terminal that is attached to the screw on the outlet cover. I've seen this on old appliances (washing machine, etc.).
I especially like the Reverse Engineering videos, and the scope videos because Daves so knowlegable about these things. EEV is always the first subscribed videos i look for when i sit down on a night after work. Yeh Bloody Ripper!!!
Actually you pronounce Utica pretty well. Except we don't actually say our Ts so it's more like "Yoo-di-kuh" as opposed to "Yoo-ti-kuh". Don't know Bill though.
I'd say the t-shirt represents 42 as a binary word. 0 for a downward bar, 1 for a upward bar... 0b00101010 42 I learn a lot from your videos, thank you!
I think it's pachinko parlors. I'm pretty sure the external ground lead is also a thing that is still around in japan, like the grounded to two pin adapters that were common in the US. I've got one of the machines, but it sadly lacks a cord of any sort, just a jack on the back for power in and I guess something out.
Nice VFD there. Anyone got an Idea why you would want to keep heating these all the time? Because that's what my stereo does, wasting power on standby. 8W for nothing. But when I turn it completely off and on, its there nearly instantly, so I dont get the point.
I've been to Utica, NY plenty. It's a lovely little city upstate. Fun fact: it's where all the NYC mob bosses keep their families so they're out of the way of all the, you know, mob activity and violence.
The Pachinko machine being made by Samsung is interesting. Pachinko is a uniquely Japanese thing... but Pachinko parlors are frequently run by people who are ethnically Korean.
Hi Dave, I dont know if you learned it already, but a thatched cottage is a type of old house, usually worth a buck load these days, which were built usually with "straw" or dry grass roofs and walls made of timber and a type of concrete/dry grass mix.
Dave: The RadioShack VU meter from the looks of it dates back to the late 90s or early 2000s. I remember selling these. glad we discontinued it; the analog one was better.
The logo on the tektronix shirt only uses 1 print color, and the rest of the color is provided by the negative space. This is one of the things the wanker design firms care about when making a logo (it's a whole set of logos, as you started to talk about). You never know when you'll have to put an all black logo on a white (etc, etc)
it is a legal loop hole to gamble and the earth ground is common it takes the place of the 3rd prong and screws to the outlet american game show had a giant version called plinko
discolour, maybe smoke, the segments dont look worn-out, maybe they are just different colours, doing a search on google images kinda shows that ' "win-view" sangyo '
Unless designed to do so, LEDs emit very little off frequency radiation. The discoloring is most likely due to plasticiers out gassing under the heat of the LEDs and reacting with the solder mask. At least that is my guess.
I have been to a Pachinko game room. This one was at a train station complex. Men sitting at a machine smoking cigarettes. The large room was full of dense smoke; could not see the back wall.

The Tektronics code is:

-Thickness: '00000011' = ASCII '♥'
-Spacing: (maybe I'm over-thinking things) '000 111 00' = '8' (not quite 'K' as I hoped)
The earth wire is a very common thing in Japan. All home appliances use it. You need to manually screw it into the wall socket.

Couldn't that yellow color on the white back be from nicotine (cigarettes)?
That was my first thought.
From what I saw of pachinko places in Japan the last time I was there, it being from cigarettes is very likely.
+yasim delzeyne Except that the darkest spots were around lights that were most likely on more often, like the top LEDs.
The first guy in the world to say " bubble wrap is dangerous"

The VFD segments may be multi colored, and that's why they look strange.
+Kenneth Scharf Exactly my thoughts. Sad that Dave did not tried turn that thing on.
if you look you can see an obvious set of 3 colors (gold, silver, copper/bronze which I'm guessing are either multipliers or just a higher value set depending) and then where there are single digits that are (basically) always on have a more off-color then the same color ones in the corresponding row/column depending on what section you are looking at.

the discoloration is likely due to cigarette smoke. there are no anti-smoking laws in Japan so pachinko parlours are filled with it.
Dave, why don't you get a nice big high-res LCD to mount on your wall, so you can tell what the HD video will look like while you're shooting? Or even just a little portable monitor? (e.g. Blackmagic Video Assist for US$500)
About the FPGAs in Ethernet test sets: You want something that can generate packets at line rate (1Gb for e.g.), and receive them, generate CRCs / checksums, and track statistics. That's a LOT to ask of a CPU, much less an embedded processor. FPGA is really the only reasonable choice.
Those orange tantalum caps on the board at 16:23 are imho horrible things. I've seen them litterally catch fire and it staying lit because of the electrolyte bubbling out it when they've failed.
Also very hard to replace when that happends because of the total lack of markings. Except for polarity, that point sticking out is the positive lead.
Allmost totally ruined a very nice Compaq Concerto vintage computer. I so very much would love to punch the one who invented those crappy things.
Never thought watching an old mailbag would get the hairs in my nek to stand up while looking at a random board. EE-Trauma. :)
Hahahahah. See at time 7:43 !!!!
Hey dude, take a deep breath of the smell by electronic components.
You´re sooo addicted, realy funny to see this.
Keep going on with your stuff man.
Btw, i like your little tiny knife. ;-))
Best regards.
Greetings from south wales the real one :) .
Should we start calling Tektronix by the name "Time Wave" now? The logo looks like T-lambda to me.
UPDATE: Ooops... I'm always writing lambda backward, too... hmmm.
The Sony Disc Player was awesome, shame you didn't get the battery pack/case as well.
I remember buying one of the first shipment to arrive in UK, don't remember the date just that I gazumped one ordered but not collected from a high street store in west London by flashing the £300 ish cash wanted for unit including battery case.
Pachinko parlors are the devil! Been to Japan/Tokyo two times and accidentally walked in to them a couple of times. They are SUPER LOUD inside. I wouldn't recommend staying in a pachinko parlor for more than a couple of minutes.
OMG that new Textronix logo sucks big donkey balls. The only correct logo is the old Tek-CRT-icon!
How I miss my HP 41-CV (same as the CX without the RTC). Unfortunately the keys died a horrible death...I had the memory card, equation library and one other card (can't remember). How I miss it. *sigh*
The Radio Shack analog dB meters were ubiquitous back in the day. You couldn't walk into a studio or lab without finding on in a drawer. They actually weren't bad for roughing in. The digital ones were crap though. We ended up purchasing a terrasonde toolbox (?) when our RS analog unit went MIA.
I think you should wear the Crocodile Dundee hat while sayin you're australian and know what you're doin and ripping apart boxes with that machete...Than almost hit yourself with bubble wrap sayin the bubble wrap is dangerous... Love it! :-)
Utica is in what is called 'Upstate New York' as opposed to 'New York City' which is at the extreme southeast corner of New York State. NY state is actually quite large and shares the border with Ontario, Canada at Lake Erie. Utica is directly east of Buffalo, Rochester and Syracuse.
It's almost 1 am in Austria and I should sleep... not with me! Not before I have seen the new mailbag! :D
The first one's ground wire in the plug isn't tied to the plug contacts, but to a ground wire in the cable. The idea for these (and also the compatible 100VAC Japanese plugs) is that the wire has a ring/fork terminal that is attached to the screw on the outlet cover. I've seen this on old appliances (washing machine, etc.).
I especially like the Reverse Engineering videos, and the scope videos because Daves so knowlegable about these things. EEV is always the first subscribed videos i look for when i sit down on a night after work. Yeh Bloody Ripper!!!
BTW, be careful opening that D50. :-) I have a D51 that I opened to fix a headphone jack. Wires everywhere. Ugh... 80s PCB tech. Good riddance.
Actually you pronounce Utica pretty well. Except we don't actually say our Ts so it's more like "Yoo-di-kuh" as opposed to "Yoo-ti-kuh". Don't know Bill though.
I'd say the t-shirt represents 42 as a binary word. 0 for a downward bar, 1 for a upward bar... 0b00101010 42
I learn a lot from your videos, thank you!
I think it's pachinko parlors. I'm pretty sure the external ground lead is also a thing that is still around in japan, like the grounded to two pin adapters that were common in the US.
I've got one of the machines, but it sadly lacks a cord of any sort, just a jack on the back for power in and I guess something out.
Nice VFD there. Anyone got an Idea why you would want to keep heating these all the time? Because that's what my stereo does, wasting power on standby. 8W for nothing. But when I turn it completely off and on, its there nearly instantly, so I dont get the point.
I've been to Utica, NY plenty. It's a lovely little city upstate. Fun fact: it's where all the NYC mob bosses keep their families so they're out of the way of all the, you know, mob activity and violence.
Why pin footprint on Raspberry header looks drunk to me :) Joey? Never heard before, hah.
The Pachinko machine being made by Samsung is interesting. Pachinko is a uniquely Japanese thing... but Pachinko parlors are frequently run by people who are ethnically Korean.
"I'd rather you actually have a new scope... that it's actually fast and responsive" Ouch :-D
Hi Dave, I dont know if you learned it already, but a thatched cottage is a type of old house, usually worth a buck load these days, which were built usually with "straw" or dry grass roofs and walls made of timber and a type of concrete/dry grass mix.
I believe you got Utica right, only way I've ever heard it pronounced, but I've also never been to NY.
Dave: The RadioShack VU meter from the looks of it dates back to the late 90s or early 2000s. I remember selling these. glad we discontinued it; the analog one was better.
The logo on the tektronix shirt only uses 1 print color, and the rest of the color is provided by the negative space. This is one of the things the wanker design firms care about when making a logo (it's a whole set of logos, as you started to talk about). You never know when you'll have to put an all black logo on a white (etc, etc)
That Pachinko data counter... I don't think the VFD display sections are discoloured. I think they're actually *coloured* Like green/amber/red.
it is a legal loop hole to gamble and the earth ground is common it takes the place of the 3rd prong and screws to the outlet american game show had a giant version called plinko
discolour, maybe smoke,
the segments dont look worn-out, maybe they are just different colours, doing a search on google images kinda shows that ' "win-view" sangyo '
Unless designed to do so, LEDs emit very little off frequency radiation. The discoloring is most likely due to plasticiers out gassing under the heat of the LEDs and reacting with the solder mask. At least that is my guess.
1:55 I prefer to think it's time and date display for their very own time machine. AE86 + 141kph = Drifting, though time? p.o
+EEVblog The first programmable calculator that I had was an HP 33C with an LED display. It was a nice rugged calculator.
Love your channel Dave, my 8 year old boy watches with me and now walks around saying, "what a bobby dazzler". Thanks for your channel!
I am surprised that hackaday thing made it through customs xD That green leafy stuff looks suspicious
So if you want to get your item on mailbag faster send it to Dave in a giant box so he opens it first to clear shelf space. :)
+EEVblog Be careful when pulling bubble wrap towards yourself mate, you could punch yourself. We're only concerned about your safety.
I don't know why but while seeing that I thought about the line "that's not a knife, THIS is a knife!". Even the accent matches...
Found this channel by accident. I know nothing about electronics. I feel so inadequate by his knowledge AND enthusiasm! :(
The code on the shirt is binary, 11010101. In decimal that's 213. Likely a reference to the Tektronix 213 oscilloscope.
Yeah, Dirk Winning, I know that guy! He get's a bunch of people together for a Repair Cafe every two months! :-)
I have been to a Pachinko game room. This one was at a train station complex.
Men sitting at a machine smoking cigarettes. The large room was full of dense smoke; could not see the back wall.
Wow! That is one impressive knife; it's almost bigger than you are. I'm not complaining mind you, I am simply impressed.
