[@jamesrbrindle]

Hey Dave, those IP phones won't have much inside of interest but a whiteboard session on power over ethernet protocol which most of them use would be interesting. Lots of basic voltage detection and switching and signalling to discuss.

[@EEVblog]

KZbin screwup TEST

[@EEVblog]

Nope, it worked...

[@IIGrayfoxII]

EEVblog Works just enough

[@Ecobion]

Dave, stop spamming your Mailbag Monday with your You Tube Rant video!

[@hendrikhendrikson2941]

Passed :)

[@gotorm2]

5:20 we work with 40W-50W and our max is about 3mm MDF. Can't imagine the beast that cut this (possibly 120W or more).

[@KOTR2003]

Dave!!! Should have edited the package at 6:00, you can see the address when the plastic moves. Just a heads up.

[@yuppiehi]

Good tips on building kits at the end. Always like watching a professional solder.

[@calmarcalmar]

I don't know, but C, with pointers and everything you have to care for, may is not the best for a beginner. So the reason for this YAL is probably because it's supposed to be way easier - why not.

[@Psychlist1972]

lol. Suddenly, Elektor stops sending packages to Dave :)

[@PeterYanTech]

Dave, the Telstra branded phone is neither ISDN nor VOIP. It is (was?) used on Telstra's Customnet Spectrum service. It's an "enhanced analog" service where the voice is analog but the signalling (on/off-hook, ringing, dialling etc) was digital.

[@ovalwingnut]

We love you doing all the heavy lifting testing... for us. THANK YOU ❤

[@simoncrabb]

I think the Telstra phone is a re-badged Meridian, which is a Nortel brand. Nortel (Northern Telecom) being a Canadian company. Interesting to see both were made in Australia though - perhaps they manufacture in more than one country. The Nortel Meridian PBX systems are/were hugely popular. I had the (unfortunate?) opportunity to be a Software Engineer in the late 90s in the BT (British Telecom) "Remote Access Customer Equipment" team that designed the internal systems that allowed the engineers to manage the PBXs remotely. This was back in the day of modems, we had to dial into PBXs to save a man in a van having to pay a visit. Ahh, the good old days before everything was just on the Internet.

[@EEVblog]

You IDIOTS KZbin!

[@iownuman619]

Do a rant about KZbin please thank you :P

[@Robstafarian]

I was practically inventing profanity yesterday, mate.

[@ClosetYeti]

KZbin, YouBroke.

[@KK4CNM]

They are driving me nuts about changing my name.

[@jfernandmy]

dnelms2 I am really irritated with that too, I hate it.

[@redtails]

25:58 Aw sweet, although Dave said in previous videos that he didn't know how to handle filming kits.. but this is a nice solution, just fast-forwarding the video showing how the kit is built! It's probably very cumbersome to build every single kit you've ever received, but this is a nice start nonetheless!

[@MiggyManMike]

The voip phones will usually take power directly as wellas poe, also voip phones can be used with free software (google asterisk) and with a pots or idns card can be mated to a conventional phoneline

[@ChongMcBong]

my favourites are the teardowns, but mailbag monday is always interesting too :)

[@JorgeHernandez-ji5gb]

A pcb design book written by you would be awesome, Dave. Greetings from Mexico.

[@tgamber]

We have the Cisco phones at my work (the one you have on the left at the beginning of the video). They are quite good!

[@brantisonfire]

nice to see a fellow North Carolina yank on the EEVblog.

[@tocsa120ls]

Hm. First thougt, with a longer pin connector, that LCD probably would sit nicely on the component side of the uC board (not the solder side), and the amplifier could be flipped too...

[@CondoreComputing]

your mailbag videos are always my favorite :)

[@TehRealCanadarocker]

Chrmoe (the guy that sent you the logo) has an awesome channel, I love that LED cube

[@Sloxx701]

As someone who writes C++ I suppose I can see the point of something like JAL when used in the context of programming PICs. It does look pretty easy to understand the code, and if it's all you want to do then I cant see too much of a problem with it.

[@CommodoreFan64]

LOL at the title it's Sunday 7:30pm est here in on the East coast of the USA, when I started watching this video ;-)

[@NonoxX57]

Laser cut wood is a great and cheap way to make mechanics. A few years ago, my school's team and I made a robot for Eurobot using this for mechanics. Almost no metal parts were used, and it made the job. Since it is cheap, you can afford to make mistakes and correct it.

[@TehGordonFreeman]

I wish I had the time, money and space to play around with electronics again :( I'm just itching to delve into it...

[@dtiydr]

JAL is actually a, could say, pedagogic and totally logic language (in contrary to any of the others) for those who have never even seen a code so it´s very easy to understand how it worlks and use pretty much right away, as seen on the examples. I mean fex "delay_100 ms" couldn´t be more obvious what it means then the code used in any other language. I don´t program but JAL was actually the first program language i saw many years ago when it was brand new that was directly understandable. Agree though that if you should go into programming for a long time you better learn one of the other common ones.

[@RossPotts]

Around 22:00 you are talking about conducted radiation. Is that why manufacturers put ferrite rings around some cables?

[@petelite]

If you wrote a book, I'd buy it and learn everything in it.

[@tech4pros153]

Dave, could those LISN kits be used to send data (obviously not high speed data) down a DC power line?? cause you could feed data in at one end of your DC line and get it back out again at the other end??

[@EEVblog]

Yes, that's possible, and not uncommon, it's called "data over power".

[@siliconwitch]

would love to see more on the LISN =D

[@JanCiger]

That large CISCO phone has even a web browser on the phone. Extremely crappy one, at that. The display is just monochrome - I had that one on my desk. I believe the Telstra phone isn't actually a VOIP phone, I believe that system was actually good old POTS + some digital stuff. We had that replaced by the CISCO mentioned above. Actually it worked better than the CISCOs ...

[@38911bytefree]

Well, first one cisco approach to VoIP were sooo expensive. I have seen a few of those and, shame of the large screen in a telephone being monochrome.

[@JanCiger]

That system was very expensive, but in the end it was much worse than the old analog one it replaced. The techs never quite managed to get the phonebooks work properly, let us see the caller's ID instead of just some dummy numbers and a lot of troubles like that. I think that there were color versions of those phones too, but we were just mere mortals and had only black & white terminals (not even grayscale, it was dithered)

[@JanCiger]

***** I am not sure whether it was exactly this model, but I certainly do remember loading a browser on the thing and it was possible to interact with it. You used the up/down buttons to switch between the individual links (similar to the old lynx text browser). It was finally useless, because the phone system wasn't connected to internet in any meaningful way, so trying to navigate anywhere only produced an error message. If you look at this image: wiki.elon.edu/display/TECH/Cisco+IP+Phone+-+Button+Layout+and+Explanation The "browser" was loaded using the button #13 if I remember right (marked as the "services" button, with a little globe pictogram). I don't know whether that was a standard preload or not - it is possible that the university had something custom there.

[@JanCiger]

***** Right, that is quite possible. To me it looked like an old Mosaic navigator, so perhaps someone was clever with the XML, as you said. What was worse is that the system was extremely idiotic - one couldn't even assign fast dial buttons or add entries to the local phonebook without going through a central website where it was configured. And then it was (or more often wasn't) downloaded into the phone. Royal PITA. However, I had the entire university phonebook there, if I wanted to spend an hour browsing through it searching for someone's number ...

[@unicodefox]

3:47 It was finished in early 2012 (or late 2011)

[@TimDousset]

Those Panasonic phones have a nice rotary encoder on the jog wheel and also LCD. The Cisco has a graphic LCD.

[@harryknoll]

Please write that book!!! I would be more than happy to buy one!

[@Portal12345678910]

Why not a PS3 Teardown?!?!?! PLEASE I've been dying for this. Why WHy WHY WHY WHY!

[@KOTR2003]

Is it Tuesday? Also like he said in the mailbag where he got the PS3, there are plenty of teardown videos for the PS3.

[@CondoreComputing]

there are hundreds of ps3 tear downs on you tube, and theres nothing secret about its construction, its been out for so long, i took mine apart to replace the cpu/gpu thermal compound when it started overheating and theirs nothing that special , just your CPU GPU , RAM ,most of it soldered onto the motherboard BLUE RAY drive an HDD , wifi/bluetooth receiver , a 300 Watt power supply , some card readers usb controller, Ethernet controller the CPU / GPU cooler and fan, resolution upscale controller, audio processors and a lot of thermal shielding, at least in the really early PHAT PS3 i have 

[@CommodoreFan64]

connly33 I agree, even though it's a custom CPU/GPU, and heat shield, the rest is nothing special, but I've only taken one dead launch fat PS3 apart after it got toasted, which was my neighbors, who bought it for the kids, which was past being saved.

[@CondoreComputing]

Commodorefan64 yeah, the launch ones were pretty bad about heat, and as is the nature of a console they got abused and left on all the time in a sealed tv cabinet or full of dust and inevitably died, from either the cpu/gpu getting cooked or desoldering itself from the board and definitely isn't worth saving unless you have professional equipment to do a cpu/gpu reball, the new slim PS3's have the GPU and CPU in the same chip and are a lot more power efficient and put out less heat, i still prefer the older models since there backwards compatible with ps2 games and have more expandebility with the card readers and usb ports, not to mention it keeps my room warm in the winter , even if i didn't need to take mine apart and clean it out i would have anyway, i have a habit of taking things apart that work perfectly fine

[@viesturssilins858]

I for one don't care a bit for PS3. You can see what is in it in many other videos already and it is as most modern consumer stuff very,very boring after you have seen the first couple.

[@jonskunator]

Just a silly pedantic observation. At 3:50 the "Not Austria" is crossed out, which would re-negate the statement, and say instead that "Austraaaaaalia" is actually Austria. Ha! Although, maybe this Austraaaaaalia isn't Australia, thus making the statement possibly true.

[@kieran_hammond]

CHR made the 8x8x8 led cube on instructables

[@allenwest1986]

Just use "Perler Multi-Mix Bead, Assorted Colors, Pack of 11000" for your stand offs they are cheap.

[@Hulkeq2]

15:10 I'm of the same opinion as you on this. The concepts are exactly the same in all languages, selections , iterations, sequences.. C and C++ have libraries to do absolutely everything. And granted, to a beginner working with threads or designing classes upon classes can be somewhat overwhelming but that's not what a beginner should be doing anyway. I would even go as far as to say, if you're a teenager and you're going to a school where they try to feed you a a 4th Gen language to make it easier for >you< they probably have teachers who aren't good enough at C and are worried they'll have to answer difficult questions. Change schools, learn C.

[@thecooldude9999]

It's pretty easy to get one of those cisco phones to work, and the nortel networks ones are pretty easy too. If you know how to configure asterisk. just google it. (P.S. the EEVblog corporate phone system!)

[@takeru51]

that micro controller 13:06 looks massive

[@frozenelectronics]

It's just a 40-pin DIP by Microchip... not that unusual at all. I've got about ten of them.

[@tekwiz99]

so the two ladies on 23:21 are needed to make up the bom list, nice

[@baghayi]

you've made remote controller for your camera for stop and recording it. Why not build another one for zooming in an out. Actually one to control with your feet. remember you scored some paddle like control in a dumpster, I was thinking of hacking them for the job.

[@shadowdarter]

Dave, I had to delete my gaming and science channel, looks like im starting from scratch again.... Google+ is a dingos breakfast.

[@WeAreGRID]

also i dont know about JAL but they use LUA in minecraft mods, and it read/writes very well, lots simpler than JAL, but it is also for simple minecraft computers where you can send imaginary code updates through the internet to download new code that you write, so i cant compare it to C :P

[@Gin-toki]

Lol, you still havn't cleaned up your table after the desoldering in video #542 :D

[@WillHandwilljan]

Hello from North Carolina!!!

[@bogdanbarbu363]

How's the PCB design book coming along?

[@bogdanbarbu363]

Nevermind, I found it. Is it still a WIP project, though?

[@ScramblerUSA]

Dave, get yourself some URANIUM ORE on amazon. :) Yes, they have it! Exactly for radiation meter testing.

[@tmmtmm]

Why would Dave buy it from Amazon?. I think you should check which country is the 3rd largest exporter of uranium ore in the world ;)

[@tmmtmm]

TMM second largest even.

[@DanTheAppleMan]

Test for self like bump hack

[@UberAlphaSirus]

Sirus I think this self gratification might work. Just testing. Not Spamming.

[@UberAlphaSirus]

Or maybe not, depends on if i reply to my original or reply to the thread, HMMM.

[@UberAlphaSirus]

Nope, works both ways. Hey anyhows. Dave, hit your head on a toilet, wake up and write out an order, it might be hard to read at first, but you will see, when your head clears, it is a list of parts that Marty could aquire at your local electronics store, to get the time circuits going. Don't do a HAL, "I'm sorry Dave, I can't do that". Daisey, Daiseeeeyyy

[@UberAlphaSirus]

BTW, I was 20RoyalSuperKing, I like this comment, Anyhows, enough spaming, it makes me fell bad. Long time fan Dave, keep it up.

[@twittwat126]

I don't know about phones but your beers are good

[@Hulkeq2]

15:10 Also some still propagate the myth that C++ is a "better" or "newer" version of C implying C will be superseded one day, as microshaft does with c#. we know this is BS. If the person learning the language is into hardware/electronics design writing a driver is one of the early programming challenges and this is where C shines, not even C++. And if you're a hobbyist having some fun with an arduino of some kind you don't want the pc end of what you're making to be in a different language of the language you use on your micro controller. Bit-packing/unpacking routines for example would be the same on both machines. Using the same language can halve your development period, being fooled into using a "simpler" language often results in not having the tools to do what's needed to be done and in a worst case scenario having to redo it all near the end when you figure this out.

[@DJTheWire]

that look very close to LUA which is BIOS based ( while true do )

[@donttrytoclick]

Hi Dave, please make another power supply video :)

[@SylwerDragon]

that left one we are still using..and it is crap :(

[@WeAreGRID]

hey if you make a book on PCB design i will order one when you get it written/published, because ive got a shop that can benefit from a book, much less myself benefit from that book, so know youve got customers lol

[@DaedalusYoung]

That JAL looks a lot like Lua.

[@TheeDrunkunMunky]

I literally have no idea what you are saying but its still very interesting XD

[@CommodoreFan64]

Guys seriously please stop bitching about wanting a PS3 tear down, way too many of them have been done, and if u want some good repair videos about the PS3, please go, and have a look at LukeMorse1, and his channel, and for other repair videos on consoles, and arcade stuff.

[@DavidLeeMenefee]

Real nice. Thumbs up! Thanks

Hi Dave, can you please clearly what the deal with "Bob's your uncle" ?

[@NumbersSans]

en.wikipedia.org/wiki/Bob's_your_uncle

[@redtails]

16:30 It somehow feels quite bad. That JAL thing is literally months upon months of hard work. Also writing that book must have taken a long time. Though I cannot help but agree that it just makes no sense to learn a dead-end language. You might as well learn that Spanish Whistling language, and an equal amount of people know what you're talking about. Jeez, why

[@dw9001]

KZbin fail... Awesome video as always Dave....

[@rhettcoulter154]

Hey Dave, are you a pom? you winge like one sometimes. From across the ditch

May be yu can test the radiation meter on a old color tv whit the brighness set to max some X rays come out.

[@SvenAlmgren]

Best address not I've seen in a long time, "AUSTRAAAAAALIA -not austria-" :D

[@juweinert]

Thought the same. And also asked myself: Why "not austria" stroke though?! So, Australia, but not not Austria?

[@MrQwedc]

another programming language makes more cash if the product goes good to buy. just like for example if you have an samsung smartphone you work only with samsung printers. So you will propably buy an samsung printer not other producer. ;-)

[@Songer80]

Good day mate. Can you do a test of what happens to electronics that use 220V on 110V? I see so many great electronic stuff in other countries and I buy them and use it there but I want to bring it back to the USA because they don't have those cool stuff. Why do they only sell expensive crappy electronics in America. A no-name Chinese inductive hotplate costs $200-$300, but in Thailand, a Panasonic one costs only $100 but runs on 220v. ...

[@rfr62409]

it never occurred to you to simply purchase a converter?

[@Songer80]

Too big and noisy. Also inefficient( I'm trying to be carbon neutral). When the USA is the largest single market, I'm just wondering why they don't sell them here.
