Here is what my dictionary says about the Chinese characters btw. It's written with traditional characters. 戴夫 Dave 信箱 PO Box 奧地利 Australia 臭狗屎 Smelly dog shit 不使用安全 No use of safety 未通過認證 Not passed certification 有毒廢料 Poisonous/toxic waste 我們不關心質量止盈 We don't care about quality only profit 戴夫是真棒非常趣 Dave is really super interesting! 大聲笑 Cashinnate(?) I hope a native speaker can correct me :)

[@Ybalrid]

It's awesome!

[@HamishMilne83]

I'm a native Chinese speaker. Your translations are good, except theese: 奧地利 is Austria (not Australia) 大聲笑 means LOL :)

[@santablaus9963]

Barnacules Nerdgasm I was laughing too when I saw someone who has a channel that I subscribed.I bet that you are Mr.Wong and you come here to see Dave's reaction :) Even if you are not; Who prepared this joke is absolutely genius.

[@fclage2]

Barnacules Nerdgasm "Qualitty" is number 1 priority! Bahahaha :)

[@roamboticsjr.7544]

Barnacules Nerdgasm the Chinese is funny as hell too

[@Zonkotron]

Daaaaaaaaaaave ! Whoever really sent you that Wun-Hang-Low package deserves an honorable special mention in your next video. That was fabulous !

[@Nostalgianerd]

After view of video, I am agree that Wun Hung Low product is very best. I go fully recommend to people I meet. Very good qualitty.

[@nicknack125]

Love the high framerate - not experiencing any blurriness or issues due to the 50fps like others are, so I don't know what's up with their situation. I'd say stick with the HFR :D

[@EEVblog]

nicknack125 Yes, I don't know what people are on about with a 50fps video on a 60fps monitor. Looks fine to me.

[@jonskunator]

EEVblog When 50 fps is shown on 60 fps panel, every 5th frame is shown double time, so it causes some minor microjudder. It's mostly fine of course.

[@HamishMilne83]

It probably depends on individual monitors. Both of mine work fine, but maybe some cheaper ones with slower response times will have issues.

[@jonskunator]

What I meant is that you can't directly display 50 fps on 60 fps panel, as 50 isn't a factor of 60. So every fifth frame will be shown for 33.3 ms while others will be 16.6 ms. Hey, it's not really perceivable, but technically there's this minor judder.

[@kyoudaiken]

jonskunator Yes, and this is very noticeable unfortunately... I argue the case for having dynamic sync like I described in another comment. The GPU might send a region to the monitor that has changed just in time.

[@fibrodad1354]

fantastic mailbag, the one hour time was brilliant, the quality was superior, the special guest openers were a welcome surprise, and the final segment was pure hilarity. thnx.

[@Bananagunzz]

it is kind of weird how much we like these mailbag videos... its pretty much like a poor kid watching his neighbors open presents on Christmas morning through the window... knowing he's not getting a damn thing. and ENJOYING IT 0_o

[@electricengineerwannabe5499]

The same with the films, porn, and books. It's because it's easier seeing it than doing it.

[@redtails]

5:08 one little side note.. the method of detecting ionizing radiation (e.g. Gieger counter or scintillation counter) determines what sort of radiation you're going to detect. For instance, GM is not suitable for detecting gamma-rays and x-rays due to the low efficiency

[@lanimereala]

A bit of clarification on the role of the antenna on the back of the PenPad. The hybrid chip on the flat flex is the wireless communication device that is used to connect to the USPS mail truck docking system that works on a 2.4 GHz system, encryped using a special (i think 256-bit encryption) connection using WiFi, and the mail truck in turn uses the internet connection provided by one of the major US carriers to reach to a server somewhere. Hope this helps. Btw, in the mail van the dock is for 2 PenPads.

[@EEVblog]

Alex Mano Thanks for the info on that, makes sense.

[@lanimereala]

EEVblog You welcome

[@TechGuyCharlie]

This looks sooo much smooth on my TV! thanks Dave!

[@MasterControl90original]

fuck 4k, 50-60 FPS are the future! PS: framerate conversions are bad, decide what framerate you want to use and set all the cameras on that (or at least the half of that). 25 and 50 fps or 30 and 60 fps, not this 25 and 60 with a 50fps conversion.

[@EEVblog]

perhaps you didn't hear. my cameras can't just be set to any arbitrary frame rate.

[@AmericanLocomotive1]

EEVblog There might be some 3rd party firmware for Canon video cameras (like CHDK for their point-and-shoots) to enable 60 FPS.

[@MasterControl90original]

sadly the framerate conversion just ruin the video quality due to frames interpolation. In this video is very noticeable due to the massive blur

[@rich1051414]

I feel you man. 50->60 fps interpolation is especially noticeable to my eyes. He cannot do anything about it tho right now, and I do like the higher framerate, even if the interpolation is a little distracting.

[@tobiaspahlsson8126]

I agree with high fps fps, oh yes! But why exclude 4k? We want *4K@60FPS!*

[@electrodacus]

For mailbag and similar videos where camera is stationary and there is not much movement 25 or 30fps is better because at the same encoding size there are less frames so each frame can be of higher quality. For places where you have the cammera hand held or there is a lot of fast movement 50 or 60fps will give better result less motion blur.

[@squelchedotter]

I Dont think file formats work this way.....

[@electrodacus]

ATschTheCube Can you elaborate? I made no mention to file formats.

[@MrThomashorst]

Sign that.

[@ryanmcdougall7470]

Wrong

[@dumle29]

***** The only thing you will change, going from 50/60 fps to 25/30 fps, is the size of the file. Lower framecount doesn't allow for higher quality frames.

[@Psychlist1972]

Also notice Wun Hung-Lo sent the letter to Austria, not Australia. I'm going to assume it's a joke, because no one would call out a cold solder joint. I'm really curious what the writing says now. Any translators here?

[@kylelafountaine8164]

I lost it at that part. Too funny.

[@winstonsmith478]

I realized it was a joke as soon as the letter reading got to "assembry line." Would have been even funnier if more Chinglish had been used. Overall, the English was far better than that found in the vast majority of Wun Hung-Lo "product manuals."

[@Ronaldvester]

According to google translate it says "Dave is awesome, very interesting"

[@Psychlist1972]

[@KingsleyKingOfHV]

The Wun Hung-Lo Factory part had me literally on the floor laughing uncontrollably, it was the serious sarcasm that did it! Thanks so much for that Dave, I do love it when people show a sense of humor.

[@markmckenzie5343]

I had to come check the comments it was so series

[@sparkyprojects]

Love the way that D9, R12, R13 have been raised from the board for airflow, so essential for cooling

[@stefanszabo2422]

Hi Dave. In the MAVO-35 multimeter, the transformer is used for AC current measurement. It is a curent transformer and the different windings are for the different ranges. Sorry for my english! Like your blog and youtube videos. Best to you and family.

[@Tarce3000]

That multimeter recall in me so many memories...

[@rickbronson3208]

Loved the Wun Lung-Lo! Absolutely hilarious spoof! It instantly brought me back to 1968, sitting around the table with a bunch of ham radio nuts and one guy mentions "one hung low". I had no clue what he was taking about at the time.

[@benheatherman2839]

According to the uRADMonitor website the last time your unit sent info was 13-Jun-2015 16:48. Did it break or something?

[@capoman1]

The Wun Hung Lo segment was amazing, just too funny. I can't believe this is real.

[@MrMisoginist]

+capoman1 It's not. I checked the chinese words with google translate and in the bottom left corner it said smelly dog feces, and in the bottom middle section it said dave is awesome fun, and next to the Mr Wong signature it said "(lol)". Also next to hot snot it said toxic waste, and in the beginning of the letter, next to wun hung lo factory it says dog feces again, and there's some other crazy stuff also, so I'm pretty sure it's not a bad translation issue.

[@capoman1]

+Ady Price Nah I think that was a prank letter. Look at 50:06 it says : "pay special attention to C2 we have soldered only partially, this cold joint technique is very difficult, only our most honorable staff can do this - it is a very clever spark gap for safety, we have lifted pads... for max cooling and safety, lifted pcb trace for max current flow and safety..." No real person would brag about these things, this is obvious satire and prank. Somebody sent Dave a prank mailbag burnt circuit with a cute letter :) I like it. I think Dave went along.

[@gnagyusa]

+capoman1 Yeah, that's because it isn't (real). It should have been an April 1st thing... That would have been perfect. Still laughed my ass off though...

[@xebek]

+capoman1 Seriously? Do you and 23 other people really need it explained to you (and them) that this was just a joke for our, and Dave's, amusement? I'm particularly amazed that you needed to research the letter's content to draw this conclusion. *Facepalm*.

[@capoman1]

xebek On first watch, I just assumed it was legit, I didn't anticipate a prank. But yes I did notice on second watch it was a prank. And damn hilarious.

Awesome episode. And Mrs. EVVblog and EVVblog Jr. are both on the show! Brilliant!

[@GadgetAddict]

50 fps but still out of focus.

[@rownadoherty]

The BAM & DICE module connectors.... just a guess, but I assume the connector type on the modules was chosen so you can release the wires without needing to remove the module from the base since it would be impossible to get a screw driver between two modules.

[@onwul]

Regarding electric IMP, there are many things making it a perfect candidate to spy on its user or to get hacked in general. Device can be programmed remotely without device showing any signs of being programmed or requiring someone to physically allow it to happen. Most likely, program is not signed or connection encrypted: device just begs to be hacked. It also seems to work only with electric IMP website. If website disappears you can throw the device out, and if some agency knocks the door of the website's owners, they will get the data and a chance to plant anything they want onto the device. To sum up: what a great device! I bet, NSA is every excited for everyone to start using it.

[@4evermade1inchrist]

4k baby,keep it coming love the new quality,image and sound quality superb. Thanks for the hard work,much tech love...

[@Falcrist]

60FPS would be better, since most monitors display at that frame rate, but 50 it a huge improvement over 25. The image looks cleaner, smoother, and sharper. I really wish cinema would move to 60fps. 24fps just looks blurry and choppy to me.

[@Falcrist]

The Hobbit only, and it's in 48fps (24fps*2). LotR was in 24fps.

[@LudicFallacies]

Falcrist It was 48 fps x 2 if you're talking the two cameras for 3D. This is a stop gap fps and expect 60 fps to dominate in the future with the Avatar sequel to mark the change in high budget production. This is 60 fps x 2 if talking 3D for a display refresh of 120Hz.

[@Falcrist]

LudicFallacies We weren't talking about 3D. If we were, I'd say 48fps stereo, which isn't the same as 96fps. Ditto with 60fps 3D not being the same as 120fps. Please don't give the marketing departments any ideas. Is the new avatar movie being filmed in 60fps? I hadn't heard that, and I can't find anything that corroborates your statement.

[@LudicFallacies]

Falcrist Yes the new Avatar films will be 60 fps or display at 120Hz 3D active or higher with passive. What did you mean by 24fps*2 in your prior statement if you were not talking left/right eye streams? The production workflow for the hobbit was 48fps for for each eye/stream or double the industry standards.

[@LudicFallacies]

Falcrist The 3D system used in CERTAIN theaters not all for The Hobbit displayed at a refresh rate of 96Hz for a frame rate of 48 for each eye. In otherwords the DLP projectors refresh rate was set to 96Hz. I am talking active shutter 3d here though and passive uses even higher refresh but with digital frame insertion processing. Most theaters are using circular polarized passive 3d from RealD at 144Hz with triple flash three frame insertion processing to prevent ghosting using 24fps per eye source material. The stop gap system used in the Hobbit production yielded an effect doubling of the frame rate for reach eye in the right movie theater with the right 3d display system.

Hooray - you've finally turned that scope over your left sholder the right way up... It's been bugging me for months :) Cheers!!

[@4CSmith]

Seconded. Thank you.

[@greenaum]

I think since the video compression on KZbin, like most video compression, only sends the differences between frames, frame rate is not going to make a massive difference. Your monitor's still gonna refresh at it's own rate, that's more important. Although since LCDs refresh differently to the old CRTs, even that's not as important as it was.

[@JeffHazardous]

LMFAO, love the troll from Wun Hung-Lo. Brilliant.

I'm not an expert with vacuum tubes but I know that at 29:14 that silvery black blob, which is called the getter would have been white. A little info the getter was used to remove the last bit of air out of the tube after it was vacuumed out. It basically metalized the oxygen. It would turn white because it oxidized!

[@chrisfrendreis7430]

At 10:00, Dave says the temperature is at 33 deg C. Well I'm familiar with Fahrenheit in the states, so I converted that and it comes out to 91 deg F. That's mighty hot for a home to be at unless no AC is being used. Only other thing I can think of is if its near a computer or electrical appliance that is running hot and has that localized area warmer throwing off the temperature reading.

[@Polaventris]

Currently you'll have to use chrome browser to view the full 1080p60fps video and on other browsers the video is still shown at 1080p30fps. Maybe someday all browsers will support high framerate videos and then the limited bandwith might become an issue, but I don't think it affects that many people. Not sure if people with bandwith issues would watch the 1080p version of the video to begin with.

[@Monkeh616]

***** All modern browsers do support 'high' framerates, and I watched this in Firefox at 50fps.

[@Polaventris]

Monkeh616 I am using Firefox 33.1.1 and I see no 50fps option on my browser.

[@kyoudaiken]

***** That's because Mozilla did not relase H264 media extensions for HTML5. And I think we have to blame Google for it. They don't want them to!

[@iCuMlOuD]

You guys do know that 50 is the PAL standard right? It's 60 for NTSC and 50 for PAL. His camera is working exactly to spec for his region. Also, KZbin has region uploading. So, for example, if he uploads a 60 FPS video, KZbin's servers might just convert it to 50 based on his region.

[@wshyangify]

[@DaniMar341]

Hello Dave and greetings from Romania. I would like to add that i really like your rightful presentation of the Wun Hung Lo product, after watching it I really decided that i`ll use further more their products and would even recommend further use of Wun Hung Lo kinda products in life sustaining systems and medical equipment, their power supplies are the best. No more Astec, Delta, Fluke etc. The Wun Hung Lo product line takes the cake. I am really looking for more Wun Hung Lo reviews in order to keep up with what`s new on the market. Nice Review on good old Mavo 35, back in the day every electronics tech/engineer would have had one Mavo on their workbench. My boy is 5 months old and it seems that he`s staying put with eyes on the monitor looking along with his daddy at your nice tear-down and mailbag sections. Keep up the good work buddy! Cheers to Sagan and all the best there is.

[@diete103]

I fixed my stuttering problem, my hardware acceleration somehow turned itself on after I turned it off a while back. The new framerate looks great, well worth the extra bandwidth! Thanks for the extra long mailbag today! P.S. I'm in Montana! Nice to see our radiation is around normal ; )

[@ciphernemo]

"Only our most honorable soldering staff can do this... maximum cooling capacity for the copper" ROFLOL! You give very honorable Mr. Wong much happy feeling with glorious review! ;-)

[@KentuckyRanger]

@ 22:53 I think that's more of a UPS (Buster Brown) delivery scanner. And the card reader was for COD deliveries. The empty bay is a mystery to me. The new ones they use now definitely has cell service, because the second they deliver a package, it updates the tracking to show time of delivery. P.S. Who cares about the frame rates... I just enjoy the content! @ 24:30 Well, that proves what it was meant for. So much for my Buster Brown theory! I never remember the USPS using anything like this back in the day. I'll bet a happy meal, because of its pristine shape, it was only used in the USPS distribution center. And used wireless communication, not cellular... The 1997 year on the screen would be a dead ringer it didn't use cellular, because cell service was VERY expensive back then. The card reader was most likely for the employee to slide their ID when starting their shift. Everything I'm saying is a wild guess, LOL! But if this was used out on a route, it would show A LOT more wear. I've seen UPS delivery drivers where their computer scanners were beat to crap! I'm sticking with my theory it was used in a USPS distribution center...

[@alynicholls3230]

I dont see a way to buy the urad or how much it costs would be neat to be a part of for sure.

[@tedjones3180]

I don't understand why the improvised "spark gap" should be wired in series with a capacitor. Maybe because the real metal oxide varistor or gas discharge tube cost several times more than a capacitor? I must admit that their solution for low cost heat sinks is interesting. They are using the one of the LEDs as a heat sink. Also they added more solder on some parts of the PCB to increase the thermal conductivity.

Thank you for the info about this uRAD project! =)

I'm loving the 50fps! Keep it coming!

[@SupremeScience]

Love the 50/60fps!

[@successfulengineer]

Great! Scope in the background is not upside-down anymore! Great mailbag.

There is some software to provide an on-screen keyboard for that Norand tablet. Multimeters like that were made to be used, and well, it's well used...

Even though this video is 2+ years old now, as a CS guy who's always had a not-so-secret love for EE (but no formal education in the latter unless you count the digital-circuit design CE electives I took out of some sick desire to solve an escalating series of multi-variable Karnaugh maps), this is one of the most interesting mailbags I've seen yet. I'm currently working on yet another "big-data" app and I really would love to know what back-end the Geiger counter used (is using?) to store and process all of those data points! I've done systems in the past which do fairly high resolution GPS tracking that "learned" to auto-classify tax-deductible business trips based on collected way-points. I would love to have conversation with these guys about the approach they took in both collecting, and interpreting, all the data coming in.

Getting the point of the written Chinese in the last mailbag is a little hard for the native English speaker, actually the meaning is completely opposite to the affiliated English sentence. He said the Wun Hung-Lo Factory was "crap". Their product quality is very low, not ever certificated. And if the product has quality they have no profit.

[@SamSitar]

how do I select the fps rate for recording videos?

[@bskull3232]

The Chinese on the paper is "safer is not used", "stinky shit", "not passed certification", "poisonous salvaged material", "LOL", from left to right, from top to bottom. The footer is "stinky shit", "Guangzhou", "Guangdong", "Dave is a good guy", "Very interesting", "We don't give a shit to quality", from left to right. The Chinese translation seems to be an enantiosis, where almost everything contradicts to the English before it.

60 FPS is actually much better than 25 FPS for video, much much smoother of course! Actual die-hard movie FPS is 24 FPS, which TVs have when viewing blurays in cinema mode, for movie buffs! For your channel, it's waaaaay better! Keep it up, I appreciate your videos a lot! Learn a lot viewing them! Kudos from a French HAM! (I know I'm bit late... :-)) )

[@zlockno]

Dave, could you please tell me some info regarding your "Letter Opener". Cheers

[@app0the]

Not sure if that's the same thing with the multimeter but by Russian standards usually the asterisk marks where the current flow will input on a meter (i.e. on a watt meter there will be two * poles and they would be likely connected together as an input for both the volt- and ammeter but then the unmarked pole of the ammeter would be connected forward into the circuit and the one of the voltmeter would be connected to the other end of the power input)

[@Tangobaldy]

I watch on an ipad. The video keeps switching from hd to fuzzyd. Im used to it now. Long videos are great. Dave could you make a website that has links to each of your videos? You've made more than 700 but i cant find them as youtube does not list all of them.

[@illustriouschin]

The framerate was immediately noticable on my big plasma before you mentioned it. good job buddy.

Any info that you can share about GPS tracking first started by Newcomb Electronics, and bought out by Outerlink as far as I know. It was originally primarily used in aircraft, but became a vehicle GPS tracking system. At the time it was quite large, and the antenna systems became a bit obtrusive for me, since I put them in many moons ago... for several fleets.

СБМ 20 Geiger tube from early 70... Still on sale, I doubt if they are in production for last few decades, probably "old-new" stock :-)
