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.
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?
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.
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.
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 :)
+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
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
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.
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.
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.
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
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
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).
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)
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.
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.
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?
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 :)
+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.
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...
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 ^^ )
i did notice the power supplies at the end, had OSRAM on them which seemed suspicious because if there were real OSRAM units they would have had better protection and a wider input range then just 60v (?)
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
+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 ;__;
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.
+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 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 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.
+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.
German SCHUKO Plugs For the win! They are the best ... even better than the uk ones kids can´t touch the pins and they are big enough so they won´t melt under high current! also it looks nice!
I should send you my proto-type flipper boards for the custom pinball machine I am working on. I have the schematics for it but nothing etched on copper clad yet. It would not be really that exciting though 50V in a ground and output. A few caps here and there a fuse and a bridge. Haha I kinda ruined it there for you but yeah not much to a flipper board. :)
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.
I love when he opens boxes with such large knives
I thought Bob had sent you a Bible at first....
Indeed
+Ian Colquhoun I think Dave's reaction would have been rather different had that been the case! :)
Classic way back Wednesday stuff.
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?

4:45-ish, forget to edit the mistake out? Good you leave em in. I like them.
+To The GAMES Deliberately left in for fun
+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!
At 23:04, you can see that Nicola Tesla is an authority consulted for the book. Pretty cool.
+Verdi Rodrigues-Diamond Missed it!
That Applied Electricity logo looks so cool!
Volume III is missing.... Owww my OCD.....
+Diggnuts
I noticed that too.
+Diggnuts Beat me to it.
I think he made a mistake and thought VIII was 3 and not 8. Look at the order he has them in.
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 :)
That Parameters Multimeter is the same model as the one's we had back in1989 in telecam Australia.

I was working in Pitt Street Carrier. 10th floor of Pitt street exchange.
I wouldn't say the Aoyue is bottom of the range, they do make some of the best Hakko replicas out there.
+TheAmmoniacal LOL!
+TheAmmoniacal I bought one and the cable failed almost immediate which I couldn't fix without another iron 😟
TheFex That's because you bought a clone of the Aoyue!
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 TH-cam XD
Those books are amazing. I'd love to read those.
Good on you, Bob. What a glorious gift!)
My heart lights up whenever Dave says "Bob's your uncle"
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.
23:05 Nicola Tesla!
Bobby Teslah! That's one sick puppy!

+Antonio Barba LOL!
4:45 forget to cut that one out, or just some unintentional laughs? lol
hi Dave. Love that "kill a watt" it works realy well for me but lcd is so bad xD cheers
I like the tip about not ruining the tips :)
That RadioShack shopping calculator box is awesome... it's like mint from 1987. lol.
Consulting: Steinmetz, Millikan, Tesla, Pupin, Thomson...
Impressive!!!

Hi dave. about the power meter, the ic inside is a CS5460
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.
25:06 you know you're getting old when you start collecting encyclopedias XD
Thumbs down for luring me over to the eev2 channel and not having the teardowns there.
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
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.
Those are rose petals. Probably a gift from a significant other.
Would it have killed Tagarno to have the zoom as a multiplier instead of a hex value? :D
4:44 You lol'd so hard on this one, you even muted yourself )))
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.
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
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).

14:30 "Stuck in the middle with you" begins playing.
17:45 England (UK) mains plugs for the win! The safest design in use around the world. :-)

+excavatoree Crap - I forgot to say the uncle in question was my Uncle Bob.
Those were def flower petals not leaves, pretty sure at least.
+PoLoMoTo2534 rose petals looked like
+PoLoMoTo2534 pressing special flowers in books was very common back in the day
The boards at 36:00 are HID lamps driver/supply boards.
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?
Under "Authorities Consulted": Nikola Tesla @ 23:04 :D
wow, those books are amazing!
4:44 i like how you tried to start it again and delete the old one at the editing
Love mailbag, this was a short one 😟
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.
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?
They changed all icecream recipes here so they're scoopable right out of the fridge ^o^
+Glychee S I usually keep my ice cream in my freezer instead.
Raisonbran648 Yeah, I think any ice cream would stay soft in the fridge lol
Thanks Raison, I would use the fact that english is my third language as an excuse but..eh xD
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 :)
How about an episode on calibrating your test gear, say without posessing expensive meters.
Perhaps using voltage reference chip or something alike.
+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.
I just use a soldering iron for sculpting plastic and foam. A cheap crappy 30$ iron does the job just fine.
It's actually a red rose petal not so much a leaf!
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.
love those old books
Went over to eevblog2 but couldn't find the eTag teardown. Am I blind or too soon?
As far as i can tell (still) not uploaded no :(. Damn tease :P.
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...
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.
+mrnmrn1
That`s what I think too. They took a decent module and then sealed it in a IP67 box.
Hmm the board is labeled osram. They usually make good stuff.
How about a shout out for NIcola Tesla in the "Authorities Consulted." That brings some serious cred to the Cyclopedia!
\
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 ^^ )
22:37 Robert Millikan won the Nobel Prize for Physics in 1923.
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.
Last PSU looks like resonance bridge, its must be in soft switch mode and do not need a heatsink to MOSFET...
Complete set? So, where's volume 3?
+sleepib Right there: archive.org/details/cyclopediaofappl03chicuoft
That hot knife would probably be helpful in removing support material
really good one, thanks
loved those books would be great to see a vid about them
Maybe some acetone to clean the plastic off the hot tips?
Pressed flower petals. I do wonder how old they are. Nice book set.
Hey! The uk plugs are great!
i did notice the power supplies at the end, had OSRAM on them which seemed suspicious because if there were real OSRAM units they would have had better protection and a wider input range then just 60v (?)

*A Rebadged Compucorp... You remember that beast, don't ya! :D
24:59 it's not complete, you are missing number III!
+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 ;__;
svampebob007 Australians... ;)
Good that they use metric though :D.
2:20 I have the same Multimeter, in my case it is Voltcraft branded, model designation 7905A
When I see you wielding that knife, I have visions of you gutting an animal on your workbench. LOL
+electronicsNmore Can't wait till he guts some old beast then! :D
15:00 literally what is the point of this. You could have sliced through this without heat with a regular knife just fine.
Dave quick question.... Where is Dave 2????!!!!!
23:04 Nicola Tesla call out
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.
36:00 Those TO220s might actually be diodes, otherwise where is the input AC rectified?
+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?

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

+Donald Sleightholme Check out archive.org for quite a few scans of different editions of those books.
yay another mailbag :)
this aoyue thingy could be useful to cut holes in plastic cases/projects.
German SCHUKO Plugs For the win! They are the best ... even better than the uk ones
kids can´t touch the pins and they are big enough so they won´t melt under high current!
also it looks nice!
6:11 Most be some analog devices energy chip for sure.
I am really happy with my aoyue soldering + desoldering station :(
I should send you my proto-type flipper boards for the custom pinball machine I am working on.
I have the schematics for it but nothing etched on copper clad yet.
It would not be really that exciting though 50V in a ground and output.
A few caps here and there a fuse and a bridge.
Haha I kinda ruined it there for you but yeah not much to a flipper board. :)
I'm tempted to send in my copy of 'Electric Motor Repair (Enlarged Edition)' 1951 by Robert Rosenberg when I manage to get a job....
Have the books been preserved digitally? It would be a worthy candidate of preservation if they are that good. 👍
+Daniel McGregor Yes, on archive.org I believe.
What happened to volume 3 of the Cyclopedia of Applied Electricity?
Bet that black gunk in the TV decoder is the assembler's blood :)
Rose petals.
That loooks liek aRose pedal and not a leaf. Pretty common to find in an old book. What does it smell like?
36:35 the chips got so hot, one of them desoldered itself..
