content: I would love to hear comment from Dave on the design of the NZXT H1 computer case and incidents of them catching fire. These has been a lot of talk about them on PC forums and to me it bring up some interesting design flaws that could affect us in PCB design. Should PCB design software flag this sort of thing up? It seems an internal 12v layer runs directly around a screw hole where the PCB is mounted to the chassis effectively causing a direct short to ground. As a result the units have been catching fire. The manufacturer has just been sending out nylon screws and nuts for people to repair their product themselves rather than doing a recall, which to me is piss poor and potentially dangerous.For an example of this see the gamers nexus video -https://youtu.be/9XIKOSrQdQ0And their follow up and response from the manufacturerhttps://youtu.be/fjUscSRLwksI think it would be interesting for a best practice video on such PCB layouts.

content: Hey Dave, if you get the opportunity, it would be super interesting to see the hardware inside an Ultimatte compositing system, vintage or modern.Here's a vintage example:https://collections.museumsvictoria.com.au/items/394653I saw this recent article on Hackaday that uses machine learning with GPU horsepower to accomplish excellent real-time high resolution background removal:https://hackaday.com/2020/12/22/the-world-is-your-green-screen/Some folks in the comments were highlighting how Ultimatte was doing this decades earlier, and I'd be curious to know how much custom hardware it took to accomplish this. It would be a nice companion teardown to the $80K vintage Panasonic NLE video editor one that you did a few years ago!

Idea for video designing a simple power supply that runs off mains - Page 1
Forum section: electronics / general

timestamp: November 14, 2020, 05:35:08 pm
content: I watched your videos on power supplies *watched almost all your videos while I was bed ridden for two years! Remember book reviews and when you didnt have as much enthusiasm in your voice?) My 1st power supply I built was your lm 317 model but it was lacking in features.I was thinking how to make a simple lab power supply that uses three basic parts:!. 120/240 to 24 or 48 vac step down linear transformer2. To display current and voltage use those volt meters they sell off allibaba and other sites where you have a XX.X volt meter thats all self contained in a 3 seven seg. display package thats all contained with two wires coming out is 1cm X 3 Cm and costs a buck or two.Doesnt have to go to 0 volts but if thats easy to do it would be a plus.That way you could have a professional CC CV power supply that doesnt use an arduino so no code and has 0.1v/A accuracy displays. Im guessing you could build some sort of voltage divider circuit that would convert the amps output to volts to run the CC display.Would be a really cool project and save the 100 bucks + that a commercial one costs; my velman CC/CV 35v 5a handheld power supply costs me over 200 bucks but its great except the limited 35 volts.This way you plug it into the wall have a power switch two pots for adjustment and your output. A bonus would be adding a circuit that trips when you go over your CC, that I have no idea how to build electronically.I would like to see it built with LM317 or lt380 to keep it simple and analog

content: The internet is full of schematics for such relatively simple linear supplies. The costs would be the mains transformer, DC smoothing caps and then your current/voltage monitor.You didn't mention current capability, which determines the size/cost of the transformer. Also, housing should be carefully done to ensure you're grounding exposed metal (but you could leave the supply floating). All of this is cost and hassle that makes the cost of a simple power supply quite reasonable. With that said, I'm sure we've all made DIY PSU's, and its a good exercise.This bit:Quote from: Beamin on November 14, 2020, 05:35:08 pmCC is constant current, that is, the output is regulated based on current flow, so the voltage is limited only by its maximum output (so the load determines the voltage). You can't go "over" your CC current, since that is regulated. Are you talking about current limiting, as in, fold back? This isn't the same.Quote from: Beamin on November 14, 2020, 05:35:08 pmAgain, because both devices are quite old, there are many many web pages detailing projects using them. You can find one, prototype and test with a separate power supply first (like a DC brick). It sounds like you have a pretty decent power supply, with 35V @ 5A with CC/CV. What features does it lack that you require?

Zoom Level Resetting in Firefox - Page 1

content: This probably is not a EEVblog problem, but I just rebooted Firefox and now it seems to have lost short term memory for the zoom setting on some web sites and not others. I have to zoom in to read the text, presently I'm at 150% zoom. Every time I click to another page within the site the zoom setting resets to 100%. In fact, I only need to switch tabs and it resets the zoom. Restarting Firefox a couple more times does not fix the issue.A google search didn't turn up anything... or actually far too much. There are tons of issues with the zoom setting going back for years. None that I found actually have these symptoms. Mostly they were more about new tabs, so the default setting in the options.I guess I can try rebooting Firefox one more time.

Handheld contactless thermometers. Good, bad or just ugly? - Page 1

content: In our Covid-19 era, at airports, train stations, shopping mals and beauty salons, etc, handheld contactless infrared thermometers are relied on to check entrants temperatures. No fever, no worries...The question is, are these measurements actually RELIABLE? When the 'normal' body temperature range is 35C to 37C, many people will have a forehead temperature of under 30C; that means they are hypothermic. Certainly not feverish.So can these handheld contactless thermometers provide a safe diagnosic? Is there a difference in the quality of body temperature readings versus device price? What is the IR detector technology anyway?Tear down time?...

Maybe we can find together best software for most common OS/browsers as well.Another option is to fetch youtube feeds and provide them over eevblog website (as "semi-proxy"), it will give Dave option to gather statistics about his subscribers interests, and he will plan his new releases topics accordingly.

For a complete reverse attitude, have a look at Olimex. They put the complete desings of their boards on github. Complete KiCad project.

Suggestion/request: Solar PV strings in parallel, blocking diodes or not. - Page 1
Forum section: electronics / general

author: SpeedyDave
author_rank: Contributor
timestamp: August 21, 2019, 01:38:10 am
content: Dave,Would it be possible to do a EEVblog video on the how and why of paralleling solar PV "strings" that would have different orientations (i.e. one string east and 1 west) connected to the same MPPT input on the inverter.Some info states that the strings must be "exactly the same number and spec" panels, or on a roof angle less than 15 gerees, or exactly east and west etc etc.I do not believe it!Given that the inverters MPPT basically is a variable voltage sink, where it clamps its input voltage (the PV output voltage) and then just lets the amps flow, and given that the PV panels/strings have a relatively high impedance, i reckon that two strings of different open circuit voltages on different orientations can easily be paralleled into on MPPT if each string is fed via suitable blocking diodes, as each string voltage will rise to the point of forward conduction of its blocking diode. Yea, the current flow will be different between each string, but I believe that each string would contribute to the total power in the same way that paralleled caps of different sizes do.I would REALLY like your highly qualified technical opinion on this ! ( this could also be highly relevant to solar pv design / install people, as it would allow for more diverse installations )CheersSpeedy

Many times, I get very helpful and personal reply. I thank you for that. But occasionally, I get passive aggressive response to do a google search or forum search. Well, I did... But google search response is not same for everybody. Somehow, google tailors output to whomever is asking. Plus, I have a certain condition that makes processing large amount of information very difficult. (which I do not want to get into). Also, these suggestions are excruciatingly painful for the same reason. It ruins my whole day or sometimes days.I know it's annoying when it's 100th time you saw the same question, and you are tempted to answer "do a search". If so, please be considerate. Some people have issues/problems that makes easy things (for you) very difficult.Thank you very much.

Re-do HP "Practical Transistor Series" of videos from 1970s - Page 1

content: One of HP's people who trained service techs, George Stanley, did a series of lessons that were put on video tape. At the time it seems they wanted to bring their service people up to speed on how the "new" transistors worked and how to troubleshoot transistor circuits. Apparently the videos became so popular that HP started selling them to customers.Archive.org has the full set of the series:https://archive.org/details/HPPracticalTransistor1https://archive.org/details/HPPracticalTransistor2https://archive.org/details/HPPracticalTransistor3https://archive.org/details/HPPracticalTransistor4https://archive.org/details/HPPracticalTransistors56https://archive.org/details/HPPracticalTransistor78https://archive.org/details/PracticalTrans(has parts 9, 10 and 11)https://archive.org/details/HPPracticalTrnasistor1213https://archive.org/details/PracticalTransistors1415Except for the last one, the video quality is very badly deteriorated. The first five parts are also athttps://archive.org/details/04PracticalTransistorsPart4, but these just seem to be copies with colour artifacts removed.I haven't gotten very far through them because I'm finding it very hard to follow the deteriorated visuals without knowing the subject matter. It seems the promise of the course is knowledge that will allow understanding of transistor circuits by inspection and to develop troubleshooting skills.I was wondering if the ideas covered in these videos could be re-done in a series of EEVBlog videos? While the "writing table" and "magnetic board" were probably great at the time, DaveCAD, the whiteboard and circuit demonstrations would be much better.George Stanley also wrote a book called Transistor Basics, but I don't know if it would be of any help.Tim

I have come to understand, this is not the case. Although the installation was easy enough, and both ringers work they are plugged in within 15' but .. no farther. What's the point in having an extender that provides no 'extention' of the ringer? Anything more than about 20' then it's out of range. Has anyone had an experience with this product?

For example, right now I count 21 (out of 40) threads concerning soldering on the first page of that section alone.Given this large population of threads in an 'other' section concerning just one thing, I think it would be a good idea to create a new sub-section entitled 'Soldering Equipment & Supplies', or something like that. Anyone agree?Oh, and forgive me if this has been discussed before in the past, but I didn't see anything recent.
