content: Hi all! Sorry if this is the wrong part of the forum but I don't really know where else to go. I ordered a BM235 from the EEVBlog Store, and as can be seenthe tracking hasn't updated in 2 weeks, so I contacted DHL in Sweden who told me that the parcel should have been handed over to the Swedish postal service (PostNord). When I called PostNord they told me that I should contact the seller and make a complaint as the parcel seem to be lost in transit. I tried emailing Dave last week, and again yesterday as well as tweeting him but I haven't received any answer, which is of course understandable as I'm sure a lot of people are emailing him, but I do think that paying customers in his store should have some sort of way of contacting him in regard of customer service and receive answers a bit faster than people sending him fanmail. So do any of you have any info about what I should do, or should I just wait until he gets to my email even if I have no idea if that is going to take a few days or weeks?

It would be nice if the forum software automatically took care of rescaling the incredibly hi-res images that modern cameras take these days. Perhaps this could be done on the client side with some JS?2. Also, it would be nice if extraneous EXIF information was remove from uploaded photos - or if that information was elided when it was served.I can do both of these steps myself, but it is a bit tedious to prepare separate versions of each image I want to attach to a forum post.

It doesn't matter if I choose the option when posting or afterwards using the Notify button. It used to work (months ago) but has stopped even for conversations I was receiving notifications for.It's frustrating because I'll post a question and assume I'll get notification if someone has been kind enough to reply. Sometimes after a few days I may happen to check and see one or more people have. It makes me feel bad because it's as if I'm being rude by not saying thanksI checked my account email address and that email account's junk mail and everything's okay.Any ideas?

content: Explaining different solder types, flux, temperature, metal compatibility etc.I loveKester productsbut they have 24 different wire solders aloneFor noobs it's overwhelming.IPA attacks the soldermask on my chinese PCB's, so using rosin-flux solder not a good idea.No-clean residue not so good with moisture for leakage current.I touched lead solder, am I going to die?

content: Water-soluble flux is an option if you can't use solvents or tolerate no-clean flux residues. Keep in mind, though, that itmustbe promptly removed, as it's very corrosive. Lead solder isn't terribly dangerous if you wash your hands after handling it.As far as rosin fluxes go, I like Kester 44. It's active enough to tin corroded surfaces, has an OK smell, and can usually be treated as a no-clean flux (at least for hobby projects).

author_rank: Regular Contributor
timestamp: April 10, 2018, 06:37:31 am
content: The C920 and the 922 have basically the same internal hardware, but different firmware.Beyond that, for the objects in the background such as the bottle looking like it is out of focus, is likely due to the shape of the lens. It is really strange in that the center of the frame is at a different focal plane than the sides of the frame.You can demonstrate this by photographing items close to its minimum focusing distance.For example at around 2 inches 5cm, you can exaggerate the difference in the focal planes by taking a picture of anything with that has parts taller than the depth of field of the lens.With this setup, you can see that with the center of the PCB in focus, the the sides of the PCB lose focus: full size:If I focus on the sticker which is farther away from the PCB, the center of the PCB loses focus, but the sides start to get into focus: full size:Overall, the lens is weird and not very well designed.

content: The method provided in those guides are designed for if you want to be able to set the focus to infinity (more useful if you want to use it with a program like sighthound or blue iris to turn it into a security camera, but it will not change the behavior of the unevenness of the focus. Basically you are just chancing the flange distance between the lens and sensor.At normal distances, it is not too much of an issue, but anything up close and you will see blurring as you get close to the edge of the frame, but that blur is not due to the the optics causing less sharpness towards the edge (all lenses have that issue, including the $20,000 zeiss ones do it, though just to a smaller extent), but you get a optical behavior that is not present on any other lens, even smartphone camera lenses. You get a weird effect where the center of the frame and the sides of the frame are at 2 different focal distances. By adjusting the focus you can get the edges in sharp focus, or the centerIt is almost as if logitech wanted to cut costs on the number of lens elements used, and went with some kind of compound lens to allow for focusing while also allowing coverage of the entire sensor.

This blinking is not unusual with LED lightning and large current pulses on the supply lines.Johan-Fredrik

content: Hi there,first off, my apologies if this is the wrong forum, please correct me if so.I am in the process of creating a video about some Korad vs. Rigol comparison. In the course of the video I mention the famous EEVblog KA3005P fail which Dave discovered (#315). I would like to include a short clip of the video (~22 seconds) in my own video, obviously with a proper caption, link to the original video and copyright notice that shows I'm not the owner. Also no audio (my voiceover). My video is not monetized and is CC-BY-SA.I'm not sure if this is considered fair use and, since I'm in doubt, thought I would like to ask. Again, not trying to steal content here. I also thought about linking my channel here so you can see the types of videos I do, but I don't want this to be considered spam. I genuinely only want to ask permission.Thank you so much for your consideration,Johannes

It was interesting.Raising Awesome guy, you know that's a model of a Saturn V rocket, that was already around for about a decade by 1978? I wasn't sure when you said you're showing the model half finished. Maybe you knew the actual rocket was already finished, but just meant that Dave hadn't finished building the model yet in the 1970s.

The standards lab tour was disappointing as I do not dabble in time and/or frequency. My hobby lab is all SMUs, voltage references and calibrated resistances, DMMs, nanovoltmeters, picoamp source, nanovolt source, etc.Your host mentioned the "cells" across the hall. I think he was referring to their voltage standard boxes. Probably Fluke 732Bs.If you get a chance to re-visit this standards lab, please ask for some discussion and eyes-on of the voltage and resistance standards.cheers....

content: It shows that I'm behind the times in two ways. I did not know that there was now a 'Huxley' too !! :-)And secondly that we are now in a day & age that such 'exposure' seems to be a problem these days.....With ZERO offense meant towards Dave, he is not 'Brad Pitt' or 'Angelina Jolie', yet, dealing with countlessPaparazzi & numerous other creeps trying to follow him home & have eyes on his kids, for the wrong reasons!!He is a proud father, & Nicole is a proud mother.... and MAYBE their kids will follow in their/his footsteps.Also, and granted, we are a bit more laid back here in Australia, and so we SHOULD be !! WE do not normallyhave to deal with the majority of global troubles/attitudes/race/freedom & general 'homeliness' in this world....'Political Correctness' (God, I hate that phrase), is rampant today, and most 'Normal' people should just getback to behaving/talking 'normally' without the influence of the 'well-meaning' (but false..) Prophets today....I have SEEN the video episodes, where Nicole & Sagan have been involved with the POPULAR and loving clips,in their regular 'MailBag' scenarios. Within THESE I see the pride that Dave shows, (and yes... keeping hisgigantic knife hidden then for 'Political Correctness'... sigh...), as he incorporates his loved ones in the openingof the weeks delivery...... 'I' would be proud of my wife & child (children) too.....Sort of related to this, haha... I recently asked about the origin of the name 'Sagan', and was informed that, yes,it WAS in relation to the late Astronomer, 'Carl Sagan'. Obviously Dave has an interest in historical people, whichis 'good', and that the name 'Huxley' was from the Grandfather of an "Aldous Huxley", a writer, novelist, philosopher.I don't know much about his 'GrandFather', but 'Aldous' himself once said in one of his famous quotes......"After silence, that which comes nearest to expressing the inexpressible, is music."That struck a NERVE with me ! :-) (I am a musician, and a lover of music...)SO many times, I have tried to 'explain' music to people, and showing physical patterns, and explaining 'Keys' justdoesn't cut it..... Then ONE day, they finally GET IT !!!! and it just happens!.... It is like Mathematics...What I am trying to say, is that a point is reached, beyond explanation, when you just 'Get It', and it becomes alanguage in it's own. I have sat with people from say Japan, France, Ireland etc etc, and somehow WE just MAKEmusic, without a WORD being spoken between us... it's an international language that we all enjoy.Our Maths, Electronics, Medical expertise from outside our 'circles'.... amalgamates and we just make music....We don't write the 'formulas'.... Visiting people & their children are handed simple instruments & encouraged.And so the next generation is keen, and performing the (then) unexplainable.Keep promoting your children, Dave & Nicole.When they leave the nest, they will fly !!! xox
