Repair videos are my favourite. Even the failed ones, it is interesting to know how to come to the conclusion they are failures.

[@ryantillotson627]

Remember when I was in these videos? Good times... Thanks for the memories Dave. :P

[@ronettreker]

Dave, repair videos are the best. It doesn't matter if you fail to repair it. It's what we learn from it that counts.

[@winstonsmith478]

I second the request for more repair videos. I don't really care so much whether you manage to fix them or not although it's nice when you do, it's the troubleshooting process that's interesting, for me much more interesting that most teardowns.

[@BowersElectronics]

Whoever sent in mail that's in McKinney. I'm over in Plano not too far away. Nice to know there is a fellow viewer nearby.

[@KarlaLopez-zc4kd]

Those painted tiles were amazing, what an artist!

[@bigtank2185]

YUP! There is a pub in McMurdo! Called "Gallaghers Pub"

[@leisergeist]

Scrolled through all the comments just to see if anyone answered that! Neat

[@R3D33M3R11990]

LeiserGeist me to lol

Dave, the new led lightning system did a great job in this new video! Way way better than the old lamps.

[@casperhito]

A ghost moved the mailbag packages in the background. Your shop is haunted Dave!

[@KitsuneCentral]

Don't worry Dave, most people in the US are not that keen on Sea World anymore either. Ever since the Documentary was in Theaters and later broadcasted. Also, that wasn't a selfie stick, it was a monopod. :P

[@bigtank2185]

Favorite part... Giving the penguin the fail button "crap product design" HAHAHA

[@sammmmko]

Cool, I'm also from Slovakia! I really didn't except to see mail from my country here, nice.

[@electronicsNmore]

That knife resembles the knife used with the surgical tool for circumcisions. :-)

[@Edu_RJR]

Dave those are "Allegro CA/CB packages" for current sensor IC.

[@shana_dmr]

That selfie stick looks pretty handy as it can work as self-defense kinetic device either (probably worth unattaching the camera first, unless it has good tele-zoom lens) :)

[@ThingsWhichArentWork]

I think that hall sensor a CQ-2092 - certainly seems to match up with the datsheet.

[@Slimpickens45]

Lighting looks great!

[@MartinRhodes1]

All day waiting for this!!!!!

[@DarrenCoull]

Hi Dave, Great vblog, even if a lot of the technical details go straight over my head! :-) Here's an idea for a quick repair video, which may appeal to many Aussies - diagnosing and repairing the Bosch ignition module found on Commodore V8's (the Holden 5 Litre) - these were same from VN through to Series 1 VT - they were discontinued in about 2012 apparently, and they fail, but no one seems to be forthcoming with exactly how to fix them (but they are fixable) - they are about $200 exchange for a repaired unit, and about $500+ for new. Some even boast how their repaired units are better than original, so wonder how? My son's VN unit has failed (Magic smoke came out) so happy to pay postage if you want to use it as a test case?

[@brucewayne-px4lv]

Where is the little minion that helped in the previous unboxing?

[@EEVblog]

bruce wayne Ryan is back at school.

[@brucewayne-px4lv]

Ah bah humbug....school? SCHOOL? Who needs school when you are training to be an eevblog minion? those youths and their aspirations...

[@Michael_Michaels]

bruce wayne got fired!!!

[@MadCowMusic]

bruce wayne He asked for a raise under the advise of commenters/viewers; long story short i don't think we'll be seeing him again XD

[@mikeissweet]

he was doing a work assignment for school credits. listen to the amp hour. very cool of Dave to participate in that for the students

[@QlueDuPlessis]

The bodge wire on the test pattern generator looks like it was designed in Antarctica is considered "Common Heritage" a far as I know. ;) You're holding the Fender Mustang upside down! :P

[@dhpbear2]

7:03 - 100 mV/A - So this is basically an isolated 0.1-Ohm resistor - Bob's your uncle :)

[@DanielGliebe]

Next time you visit San Diego, go to the San Diego Zoo and the Safari Park. Much better than SeaWorld. :-)

[@cozzm0AU]

23:59 - there are ghosts in the EEVBlog Lab ! (mailbag articles in the background fall)

[@toddberg3892]

Like the way the penguin twitched faster when he took a dive - like ED-209 (TUX-209?)

[@JacobJonesy]

Did you just release a mailbag and two other videos tonight? DAVE IT'S 2AM AND I JUST GOT OFF WORK! NOW I CAN'T SLEEP UNTIL I'VE WATCHED THEM ALL

[@MadCowMusic]

I outa send in a few repair projects with the parts and trouble shooting worked out for yah mate!

[@PeterCCamilleri]

You need to add a disclaimer: "No plastic penguins were harmed in the filming of this mailbag segment"

[@MrOffizier]

Looked like that penguin had an epileptic attack.

[@MrChookchaser]

Dave your scope can't trigger on the composite color video signal because the 4.43 Mhz color sub carrier is going as low as the horiz sync pulses. The sub carrier can't go below zero or cut off i.e the top of the horiz sync pulse.The horizontal sync pulse should be .3 Vp-p relative to a 1 V p-p video signal

[@IRCXDS]

Dave, you New Zealanders are a funny bunch!

[@twocvbloke]

Hook that signal generator up to a telly, got to see it's outputs on a proper screen... :P

[@joacimwennerberg8310]

I enjoy your mailbag very much. Good entertainment. :-)

[@DavePoo]

29:15 - It's called the Headstock

[@JordanEdmundsEECS]

Why don't you like square traces? (Other than ugliness) I was under the impression it only becomes an issue at RF frequencies.

[@ronaldspanjic5384]

Nice mailbag.

[@Appalling68]

"Bobby dazzler?" "Winner winner chicken dinner?" A little bit "how you doin'?" I LOVE the way you folks down under talk. It's English, but not really. No, it's Australian, mate! LOL! Thanks for all the great vids, BTW.

[@KostadinIVKostadinov]

That penguin killed me xD

[@maesto]

That bag looks great for screwdrivers...

[@Michael_Michaels]

That fail button should be near you Dave!

[@thenwhoami]

Check out the Mr. Carlson's Lab channel for amazing repair videos... Paul often makes his own PC boards for repairs, and fits a ton of detail into a video that's over an hour long. Love em.

[@ronettreker]

It's called a MONOPOD. Don't insult the photographers among us with "selfie stick"...

[@ivanv754]

Haha Dave looks like 20 years younger with a cap on.

[@BrentBlueAllen]

Really missed out on an opportunity for "Hi to all my Antarctican viewers."

[@Thanson199415]

MAILBAGGGGGGG YEAHHHHHHHH

[@NonsensicalSpudz]

no worries? i like that phrase, but i'd just like to say I wasn't worried

[@TshacTSDMM2015]

Hi Dave, is it possible (at any time in near future) for you to get a Fluke 190-104 Scopemeter to review and tear down?

[@aserta]

Is it me, or that bodge wire was planned? Look at the drawing at both ends. I'm not familiar with them enough but, it kinda look like a tie down point sign. Kinda...

[@thermosinthesis]

You missed the note for the guitar in the last mailbag...

[@vankiu]

it is Bratislava :)

[@whitcwa]

That pattern generator has low sync level, and high chroma. Together they were messing up the scope's trigger. I noticed a 625/624 switch. Pal is 625 lines. Anyone know what the 624 position is used for?

[@mattkoester2852]

Hi, shouldn´t there be a protected earth connection on the chassis of the isolated current measurement device when you are using higer voltages....???

[@SpudderRail]

I wasn't expecting a dagger that looks like it came from Aladdin to be used to open the box...

[@DantalionNl]

If I use my scope without the earth connected do I still have common ground when using an unisolated testing device.

[@MicrowaveGenocide]

yes?...I think...

[@DimitriRoegiers]

I would love to buy a t-shirt, but shipping is too much. Maybe offer them through a european store also?

[@jakecrowley6]

Actually found the selfie stick for $39.99 on Amazon.

[@Bee_Holes]

Mailbag!

[@XPLOREanXPLODE]

"Dance, damnit!" :D

[@XOIIOXOIIO]

Well, with that erol comment I guess dave uploads his videos when they are pretty fresh, I figured he might do them in a week advance or something in case he gets sick.

[@PlasmaHH]

EEVblog again when you fiddle with the bubble wrap it sounds distorted like underwater like in quite some of the last videos too. any idea about that?

[@worldgate989]

What goods a present if you don't have to work for it? ;)

[@Mazsul]

Best ending ever :D

[@AmauryJacquot]

the slovakian voltmeter dating from the 80's would use east-european or russian chips. hence, the unknown references

[@spinningquad8700]

McMurdo's nickname is Mac Town.... so yes it looks like a town. :) Maybe you should get people to send in their broken shit for more repair videos.

[@daskraut]

24:00 oh look a little tiny linux :)

[@Nermash]

50 ohm output impedance of current meter into 1 Meg input impedance of Rigol scope. Shouldn't that actually be half the displayed voltage ergo current? Young players error, Dave :)))

[@mike7958]

Think you need to mount your fail button a little closer.

[@44R0Ndin]

Mike Mundell I think he could figure out something a little more sophisticated. Something like putting a normally-open push-button under the desk, and wiring it in parallel with the switch inside the FAIL button using some Cat5/5e/6 wire (probably have to be solid core as the other stuff is a real pain to solder). I almost did something like that once with a wireless doorbell button and a roller-lever microswitch to detect people opening the front door of a shop. The electrical side of the design was sound, but I lost interest in the project before figuring out how to mount the switch so it did what I wanted it to.

[@willlovesbearzd810]

where can I get a fail button? I Really need one!

[@bland9876]

anyone notice the ghost knock over the packages at around 24:00

[@tbbw]

Note to self... dont bid on any spare batterys in daves ebay store ;)

[@Michael_Michaels]

McMurdo sounds like a _god-forsaken_ land!!!

[@snailduck]

Can't believe people are sending selfie sticks to Dave now, for fucks sake.

[@kalhana_photography]

Looks like an Allegro current sensor.

[@LeonoraTindall]

Don't worry Dave, everyone here hates SeaWorld too :)

[@rickyoswald]

Is his anon name just the letter L? Probably a reference to Ryuzaki from Death Note.

[@grdv10]

Nice!

[@artifactingreality]

What was wrong with what the autorouter did, lol?

[@44R0Ndin]

artifactingreality It would have been more reasonable for that trace to connect to the bottom of the pad, instead of going right between two pads. It's not just a matter of looks, either. That smaller gap between the trace and the other pad would make it easier to make a solder bridge short out the two pads. Maybe it's not such a big issue with thru-hole components because of the relatively large traces and distances between component pins, but surface-mount components are packed so tight and the pins are so close together that it's already challenging to avoid bridges WITHOUT a bad board design working against you.

[@micnor14]

"scope-ception"@11:20

[@eurobum2012]

@ Andoni Z > Czechoslovakia doesn´t exist anymore XD chz probably refers to the Czech Republic xD I'm pretty sure Dave is aware that Czechoslovakia doesn't exist today, or he wouldn't be talking about "Slovakian" viewers. However, Czechoslovakia did exist when the product was made. Use your brain a little bit.

[@Sloposse]

beyond economical repair means fucked if i know aint got a scooby lol

[@grunebanane6340]

I think you need some makeup, because of your new lights.

[@anajay78]

That's not a knife...this is a knife.

[@camerontechstuffs]

anajay78 lol i get it

[@xXxbastek]

economy shouldn't by criteria on this repairs, but amount of knowledge to improve

[@44R0Ndin]

Bartosz Marciniak Most of the time I would agree with you, but sometimes it's not "economic" to repair something because you can't get parts no matter how much money you want to spend, or tracking down the specific part needed would take 6 months, or other factors that might not translate directly to "it costs too much to fix this thing". Sometimes the five dollar or five minute fix teaches you more about how something works than the 5 week or 500 dollar fix.

[@xXxbastek]

44R0Ndin but this channal is not about fixing, but about learning electronics. I wound like to see 5 week 500 dollar beyond economical repair :D

[@worldgate989]

Your saying it wrong, its Aluminum... al-lume-in-num. ;)

[@worldgate989]

eob2000 The winky face at the end denotes sarcasm. :-D

[@Powolny]

***** In fact, it's amelinium. A-me-li-nium. And you cannot paint it over. #pdk

[@worldgate989]

eob2000 Yea, it happens. I used to be the raging guy but after a while you calm down. :D

[@jozefbeska9877]

Slovakia! yes there have been slovakian packages before

[@SS-kf6nq]

Review thynx

[@SimpleEnough2k9]

I really don't think I would get the current tester at $290US + $60US Shipping. That would be close to $450CDN !!! The price / quality ratio isn't in the range I'm looking for.

[@seanhornibrook]

23:55 G G G G GHOOOOSST!!!!!!!!

[@ryantillotson627]

Sean Hornibrook RUN DAVID! YOUR PLACE IS HAUNTED! AAHHHHHH!

[@BenjaminGoose]

Sean Hornibrook You mean the package moving at 24:00? Took me a while to figure out what you meant. :p

[@spoderman15]

little bit too soon maybe 23:58 or 23:57

[@Space_Badger395]

Is it me or Daves head looks a little to big for his body in this video? :D

[@rhkips]

I like to think of Antarctica as a big international scientific cooperative playground, free of socio-political influence. :] Your entire house is themed? That. Is. AWESOME! :D

[@_Piers_]

Just because something is a stereotype, doesn't mean it isn't true :)

[@leviathanx0815]

That cam stick could go as a weapon....

[@modalen2]

Dave got trolled :P

[@zarzosaandoni]

Czechoslovakia doesn´t exist anymore XD chz probably refers to the Czech Republic xD

[@UberAlphaSirus]

Sound gets out of sync really fast on mobiles. Is this a 60fps issue. Unwatchable.

[@drkastenbrot]

Not for me

[@pixilatedpig]

Under 301

[@sonyericssoner]

yay Slovakia :D

[@SixWildKids]

Is that a battery in your undies...?
