At 24:56 you show us all 7 volumes and there are indeed 7 books but no volume 3 or III, there is however a volume 8 or VIII. So you have Volumes 1 and 2 and 4 and 5 and 6 and 7 and 8. What the?

[@Henchman1977]

I thought Bob had sent you a Bible at first....

[@polluks2]

Indeed

[@samgab]

+Ian Colquhoun I think Dave's reaction would have been rather different had that been the case! :)

[@0xCAFEF00D]

Classic way back Wednesday stuff.

[@cornboy3]

At 23:04, you can see that Nicola Tesla is an authority consulted for the book. Pretty cool.

[@EEVblog]

+Verdi Rodrigues-Diamond Missed it!

[@timekeeper5275]

I love when he opens boxes with such large knives

[@Diggnuts]

Volume III is missing.... Owww my OCD.....

[@SlyPearTree]

+Diggnuts I noticed that too.

[@WillehWark]

+Diggnuts Beat me to it.

[@isavedtheuniverse]

I think he made a mistake and thought VIII was 3 and not 8. Look at the order he has them in.

[@Teth47]

Aoyue isn't awful, gets the job done as far as I've experienced, we've got a few of their products in the shop, and while I'd rather have something not shit in there, until I can afford it, they actually function pretty great.

[@macro820]

23:05 Nicola Tesla!

[@QoraxAudio]

Bobby Teslah! That's one sick puppy!

[@Feedback_Jack]

That Applied Electricity logo looks so cool!

[@ToTheGAMES]

4:45-ish, forget to edit the mistake out? Good you leave em in. I like them.

[@EEVblog]

+To The GAMES Deliberately left in for fun

[@therestorationofdrwho1865]

+EEVblog you should have cut it before you restarted that line so there wasn't the awkward pause to edit it. Lol! Let's crap open!

[@alextrofimov7947]

Good on you, Bob. What a glorious gift!)

[@Andreas_Mann]

My heart lights up whenever Dave says "Bob's your uncle"

[@JasperJanssen]

Assuming you can trust the labeling, those power supplies are by OSRAM, according to the board labeling. And that's pretty much an A-grade lighting manufacturer. I suspect these are not supposed to be used as bare boards in plastic enclosures, and/or they're supposed to be used with forced air, and/or they're fake as a whole, and/or they got stuck with a bunch of fake parts.

[@therestorationofdrwho1865]

I love how at the start when you say hi, it's so welcoming because I'm Australian too and I rarely hear an accent like mine on KZbin XD

[@AntonioBarba_TheKaneB]

+EEVBlog the "Ritocco" written on the carving tool means "retouch" in Italian, just a fancy way of putting italian names on stuff to look fashionable :D

[@EEVblog]

+Antonio Barba LOL!

[@giannisloukovitis1256]

I used to put leaves and petals in books in order to dry them up and take them out completely flat when i was little :)

[@JessHull]

that leaf actually looks like a rose petal. Which might make sense considering people used to (or still do I suppose) press flowers in books.

[@leonkernan]

Went over to eevblog2 but couldn't find the eTag teardown. Am I blind or too soon?

[@slindenau]

As far as i can tell (still) not uploaded no :(. Damn tease :P.

[@TheAmmoniacal]

I wouldn't say the Aoyue is bottom of the range, they do make some of the best Hakko replicas out there.

[@EEVblog]

+TheAmmoniacal LOL!

[@MrFexelein]

+TheAmmoniacal I bought one and the cable failed almost immediate which I couldn't fix without another iron 😟

[@TheAmmoniacal]

TheFex That's because you bought a clone of the Aoyue!

[@lollandster]

Thumbs down for luring me over to the eev2 channel and not having the teardowns there.

[@LazerLord10]

4:45 forget to cut that one out, or just some unintentional laughs? lol

[@sordhacker]

I like the tip about not ruining the tips :)

[@proyectosledar]

hi Dave. Love that "kill a watt" it works realy well for me but lcd is so bad xD cheers

[@hmack22]

Could you do a whole video on the Cyclopedia and/or any other vintage reference books? I love how old reference books are written and illustrated. Often times much more clear than modern books on the same topic.

[@redtails]

25:06 you know you're getting old when you start collecting encyclopedias XD

[@DoRC]

Those books are amazing. I'd love to read those.

[@lamelama22]

That RadioShack shopping calculator box is awesome... it's like mint from 1987. lol.

[@sleepib]

Complete set? So, where's volume 3?

[@mbirth]

+sleepib Right there: archive.org/details/cyclopediaofappl03chicuoft

[@OzyWizard1973]

That Parameters Multimeter is the same model as the one's we had back in1989 in telecam Australia. I had mine hidden on my second last day of work, because I was warned the Install techs would pop the hinge on my tool box before the start of the last. Thus anything missing would be put on there bill... :) I was working in Pitt Street Carrier. 10th floor of Pitt street exchange.

[@H32-u7d]

4:44 i like how you tried to start it again and delete the old one at the editing

[@aiden287]

I wonder if I could attach a spoon to one of those carving tools and use it to get my ice cream out the tub?

[@jesuishalil]

They changed all icecream recipes here so they're scoopable right out of the fridge ^o^

[@Raisonbran648]

+Glychee S I usually keep my ice cream in my freezer instead.

[@aiden287]

Raisonbran648 Yeah, I think any ice cream would stay soft in the fridge lol

[@jesuishalil]

Thanks Raison, I would use the fact that english is my third language as an excuse but..eh xD

[@3JIbIDEHbv2]

15:20 Is this not a rubber potholder for a quick change is hot pressed? It's not like a sponge for cleaning soldering tips.

[@FrankSandqvist]

Would it have killed Tagarno to have the zoom as a multiplier instead of a hex value? :D

[@IllSkillz]

4:44 You lol'd so hard on this one, you even muted yourself )))

[@MichelPASTOR]

The boards at 36:00 are HID lamps driver/supply boards.

[@twocvbloke]

Fun fact: The standard Aussie plug was designed and created in the US of A, and is still used in some installations for 240v, so, the aussie plug is a funny old merkin plug... :P

[@richfiles]

Under "Authorities Consulted": Nikola Tesla @ 23:04 :D

[@chaos.corner]

14:30 "Stuck in the middle with you" begins playing.

[@mrnmrn1]

36:03 These lamp drivers are OSRAMs! Maybe not just their failure, but the lamp manufacturer's, e.g. insufficient air flow around the board.

[@zlotvorx]

+mrnmrn1 That`s what I think too. They took a decent module and then sealed it in a IP67 box.

[@andrewhellershanks8315]

What happened to volume 3 of the Cyclopedia of Applied Electricity?

[@SelinicaHarbinger]

The touch up tool makes me think of a woodburning pen with cheaper build quality by appearances and fancy features to try and make it seem more expensive. Also, four big mosfets on the primary side? They using active rectification?

[@oskimac]

Hi dave. about the power meter, the ic inside is a CS5460

[@australianstig]

Got to leave that watt hour meter switched on for a few days to see how long it lasts as my one of those lasted a total of three days before the power supply in it failed

[@TeslaLegend]

Consulting: Steinmetz, Millikan, Tesla, Pupin, Thomson... Impressive!!!

[@Seegalgalguntijak]

Where are the promised videos on the eevblog2 channel? I haven't seen them there yet!

[@photohounds]

The yellow one's like a "TES" branded meter I still use as a backup meter - you're right, not much to 'em but after > 30 years it still works and measures within a digit of my Flukes ... (probably because I'm careful with it, cause I know it's a cheapie) - great segment :)

[@adamlumpkins2000]

Dave quick question.... Where is Dave 2????!!!!!

[@blargo]

Probably a basic question, but what are the vertical springs on the multimeter PCBs in the first 5 minutes for? Do they make contact with the inside of the case for ground or something?

[@mikeissweet]

+Blargo Correct. I take it you noticed that brief glimpse of some metallized tape on the inside of the case. This is used to shield against electromagnetic interference coming in and out of the device; just as the metal screen in the window of your microwave mostly eliminates the radiation that would otherwise come pouring out.

[@blargo]

I was looking for a shot of the inside of the case where the springs might make contact, but didn't catch it in the video. Thus the question. Guess I didn't watch closely enough!

[@brochan11]

22:37 Robert Millikan won the Nobel Prize for Physics in 1923.

[@PoLoMoTo2]

Those were def flower petals not leaves, pretty sure at least.

[@jwgmail]

+PoLoMoTo2534 rose petals looked like

[@chartle1]

+PoLoMoTo2534 pressing special flowers in books was very common back in the day

[@themaconeau]

You could argue that at 23:36 that solar is part of the sentence however, wireless power is kind of a thing. By no means mainstream.

[@someperson42]

I remember that we always brought a calculator to the grocery store when I was a kid, because we could only afford so much. It was just a cheap 4-banger though.

[@spikester]

What was cheap about that SMPS in the ATSC digital TV box? I saw Nippon Chemicon and Rubycon caps, which says it isn't too crusty, had input filtering and proper MOV's...

[@TheDessonator]

Is there a reason for putting certain teardowns on eevblog2?

[@EEVblog]

+TheDessonater I just wanted to finish this mailbag yesterday. Shooting the teardowns as well would have delayed it.

[@DarkInsanePyro]

+TheDessonater Yeah I thought that was weird... its a bit on-topic I had thought...

[@electronicsNmore]

When I see you wielding that knife, I have visions of you gutting an animal on your workbench. LOL

[@richfiles]

+electronicsNmore Can't wait till he guts some old beast then! :D

[@uksa007]

no sign on the tear-downs on EEVblog2????

[@EgoShredder]

17:45 England (UK) mains plugs for the win! The safest design in use around the world. :-)

[@weedbright]

Great videos. I made an either/and counter on minecraft with my 7 year old nephew. He liked it didn't fully get it but liked it, he is getting older I was wondering if there are any other electronic chips that are basic that I could go over with him to help us both understand these videos better. Everyone liked to break things down when we were younger but rarely do we learn much from it, these are great. It nice how you break things down to the smallest scales, knowing everything. Anyone can give suggestions for chips/circuits to make on minecraft, nephew is smart and I'm trying to encourage it to it's fullest.

[@gubelly]

How about an episode on calibrating your test gear, say without posessing expensive meters. Perhaps using voltage reference chip or something alike.

[@verlicht]

24:59 it's not complete, you are missing number III!

[@svampebob007]

+LoverOfPhotography And for a complete seven volume set I wonder why there's a number 8? he put it in the third place but that's clearly how you write 8... Also why did he arrange them from right to left ;__;

[@verlicht]

svampebob007 Australians... ;) Good that they use metric though :D.

[@onesimpleclik]

wow, those books are amazing!

[@PINKBOY1006]

On the tv converter, I don't Know if you saw the caps, but they were nippon chemicon or united chemicon filter caps and output smothers I think too.

[@niino4329]

Obviously, some battery has leaked horribly in this optical attenuator. I've taken apart old stuff where batteries have leaked, and everything was exactly like in the video, including the peeled away screening paint in almost every single part of the case and the grey-ish stuff everywhere.

[@jeremyhall7259]

Wow, under Authorities Consulted 23:05, that really gives some good credit to that book! I would love to keep a set of those just because of that!(And because its 1924 electric and the book is cool anyways)

[@madhunugg]

hey Dave... are you missing volume 3 of the cyclopaedia?

[@rich1051414]

Those are rose petals. Probably a gift from a significant other.

[@peshozmiata]

You can attach a tip like that to a soldering station and get the same effect... People do this to repair cracked car bumpers and other such parts.

[@fishbong]

2:20 I have the same Multimeter, in my case it is Voltcraft branded, model designation 7905A

[@Wompylulz]

Wow Robert Andrews Millikan is in those Books, he's the physicist that calculated the charge of the electron, Plank's Constant, named cosmic rays and more! That s amazing

[@khronscave]

+EEVblog Dave, i've got a hunch you might've gotten the input and the output mixed up on those lamp driver boards. Why would a 60V *input* need three caps in series, and so much separation between the tracks, hmm? :) If anything, that looks to me more like something resembling a CCFL inverter, with those freestading FETs making up a full-bridge driving that "quad-bobbin" output transformer.

[@zer0b0t]

When you break component leads like that, is there any way to fix them?

[@funkyironman69]

36:00 Those TO220s might actually be diodes, otherwise where is the input AC rectified?

[@funkyironman69]

+funkyironman69 Ah there 19N20s, that's weird isn't it? They should only need two transistors for switching? Maybe the other two are being used for synchronous rectification or their using the internal diode?

[@funkyironman69]

+funkyironman69 Okay, it's a full wave diode bridge using the internal diodes. Two pairs of FETs, each joined Source to Drain. One AC input goes to each midpoint. The Drain of the top FETs in each pair are joined together by jumper J5. I'm assuming the sources of the lower FETs in each pair are connected together by GND.

[@funkyironman69]

+funkyironman69 And to top it off, the output is most likely a simple dcdc boost converter. A FET and free wheeling diode, both on the heatsink and a large inductor on an EE bobbin.

[@EEVblog]

+funkyironman69 Wow, I didn't notice that.

[@bigeteum]

why some manufacturer erase the chip numbers?

[@antsgamingvideosn2b]

RadioShack is still trademarked here by General Wireless according to IP Australia even after Dick Smith's closure (remember a lot of RadioShack branded gear from Tandy and DSE).

[@mshahabas]

Is there a 40 deg organic solvent mixture in your bloodstream Dave?

[@DonaldSleightholme]

The cyclopedia of electricity volume 3 is missing Viii is volume 8 🤔

[@madmodders]

+Donald Sleightholme I noticed the same thing. And it clearly says eight volumes in red lettering inside, right under the 2000 engravings-text. I saw a 1909 version of the set when I searched, and that only includes 6 volumes. Maybe there is an earlier seven set.

[@artelse]

+Donald Sleightholme Check out archive.org for quite a few scans of different editions of those books.

[@bilal11]

23:04 Nicola Tesla call out

[@richardbrobeck2384]

love those old books

[@MrFexelein]

Love mailbag, this was a short one 😟

[@TonyBarr99]

How about a shout out for NIcola Tesla in the "Authorities Consulted." That brings some serious cred to the Cyclopedia! \

[@DanielMcGregor]

Have the books been preserved digitally? It would be a worthy candidate of preservation if they are that good. 👍

[@EEVblog]

+Daniel McGregor Yes, on archive.org I believe.

[@redtails]

15:00 literally what is the point of this. You could have sliced through this without heat with a regular knife just fine.

[@CH_Pechiar]

The power supplies are branded Osram ! That's why they look nice and tidy. EU look. If genuine, it is difficult to understand the thermal design flaw.

[@digital4282]

I'm surprised you missed the Rubycon caps in that digital TV converter :)

[@khronscave]

+Telvana It's not the first time. And apart from the brown glue that darkens and goes conductive with age, that power supply's not even all that *ahem* "crusty". Sometimes i get the feeling Dave just rushes through stuff like this just for the sake of "wow factor" or something :/

[@38911bytefree]

6:11 Most be some analog devices energy chip for sure.

[@TwinPeaksIndustries]

Those are pretty ancient books and surely quite interesting to read (Though I can definitely beat you on the ancient department here with something I have lying around ^^ )

[@santopino2546]

My tollgate transceiver has never had a battery change in 10 years, how's that possible?

[@LazoeJSCREI]

24:56 Complete? So there was no volume 3? You have 1, 2 ,4, 5, 6, 7, 8

[@daveb5041]

It's actually a red rose petal not so much a leaf!

[@sanderkoster9680]

Hi Dave, those drivers appear to be partially real. The low voltage driver board looks be a genuine (or very good knock off) of an Osram PT-VIP GEN 4 UART board. Cheers, fun video as always :)

[@dhpbear2]

32:50 - Alphabetic key-arrangement, digits on bottom row (most of 'em) - FAIL! (At least they put a period after the 'Z' so I know where the alphabet ends :))

[@JeanYvesB9]

What happened to David 2???

[@redtails]

36:35 the chips got so hot, one of them desoldered itself..

[@tom_something]

Maybe some acetone to clean the plastic off the hot tips?

[@Psychlist1972]

Pressed flower petals. I do wonder how old they are. Nice book set.

[@excavatoree]

The "Cylopedia" is similar to a set of old :Hawkins Electrical Guide" books my Grandfather had. I borrowed two of them, but never returned them. My Uncle sold or threw them away without mentioning them to me, so I couldn't add the two missing ones to the collection. I still have the two volumes. A complete set in poor condition goes pretty good money on E-bay. I never found a cheap set missing the volumes I have, however.

[@excavatoree]

+excavatoree Crap - I forgot to say the uncle in question was my Uncle Bob.

[@wald01979]

That loooks liek aRose pedal and not a leaf. Pretty common to find in an old book. What does it smell like?

[@richfiles]

32:11 No, I've never taken a "shopping" calculator to the store, but I HAVE taken my Monroe* 344 Statistician programable calculator to the store to do shopping... I needed to buy 4 more "D" size batteries for it anyway, and figured I'd finish them off! :P *A Rebadged Compucorp... You remember that beast, don't ya! :D

[@jwt27]

9:27 Pick up an aoyue by the hot end. Now you'll know how to pronounce it.

[@anon5214]

Dave, I got to say the audio quality gives me the heebie-jeebies, especially when you remove wrapping in the packages! Please use higher bitrate for audio next time.

[@NadolbenBlogspot]

Last PSU looks like resonance bridge, its must be in soft switch mode and do not need a heatsink to MOSFET...
