content: Hi Dave. In one of your reviews of the "Saleae" Logic analyser, you were using an old version of their Software,(yours being Ver 1.1.15 I think), and were complaining about the limited number of 'Analyser' options.....The LATEST version... (1.2.14), has a vast improvement there, including the 'JTAG' you would have liked.OH!!! and it includes mouse dragging the channels up and down in the order you want !!! :-)Here's a 'pic' of the selections now, for Logic Analyser options......Also, when you have used 'LTspice', your version is (was) version 'IV' (4), but now there is version 'XVII' (17).Have fun Dave. Both softwares freely downloadable....

Europeans tended to use more bands for their broadcasting with frequencies like 6 MHz providing massive signals to the whole continent from just one transmitter. However they also seemed to be abandoning them quicker, starting with longwave, then shortwave, MW and even analogue FM.

content: I was already typing a similar story like this (acoustics, audio and mics is one of my expertise), but you already got everything pretty much.There are a few little details I don't completely agree on, but meh you need so much context/explanation to make that more clear, so we just leave it.What I can add is that you always want some sort of cardiod pattern to keep the 'room noises' down or prevent feedback.Obviously they are making some sort of compromise costs vs performance with this.Btw, this mic is also mono (read the manual!)("For stereo miking, use two Go Mic’s" and "Set up a mono record track in your DAW")So you could have known that these are not a stereo pair, but form a summing pattern as Doug said.Never mind, apparently you can choice what to use.As on the website: "Thanks to its switchable cardioid and omnidirectional pickup patterns, you can pick whichever pattern is more appropriate for your specific situation."So you still could have knownJust some practical information.Most (cheaper), small devices all have these little buggers.A lot of times they might look like a fancy other type of mic, but that's just marketing.

In the older datasheet I originally had (at work we use common components and store datasheets on a local server) happily said the chip worked down to 3V - Goody, I was designing with 3.3V. The new datasheet changed this to 3.7V. Fortunatly, I spotted this before I had the PCB laid out.

content: A Proposal For YoutubeA proposal for a second bite of the sav, Dave?interesting concept, But I do not think Youtube will let you do this for a lot of reasons.it has always been the responsibility of the video publisher/content producer to get it right the first time.a total product recall is your loss as a publisher/content producer, some go's for movies or video games on disc.the need to spend more time checking your content. as you have said in your videos,that you do not watch your own videos a lot of the time,not checking your own content before posting it, is a bad idea.however Youtube may or can add a online video editer for head & tail advertising clips. however this is up to Youtube.if Youtube let total recall & repost of content then. loss of credibility for Youtube,for all comments, as the video had changed.just imagine if The movie industry did that. changed or swapped out a movie but kept the title & original movie reviews.as for embedded advertising, if that advertising is relative to your video then that is not a bad thing. as some out of date advertising can be a time capsule. if you need advertising to help pay your way. just add a legal disclaimer in your video,saying you do not necessarily indorse or use this product unlss its part of the main video.if Youtube is your life, advertising maybe a necessary evil you need to live with.as some of us still see Youtube as a hobbywith no interest in making a living from it.

content: I think this idea has a lot of merit, but it will need some provisions in order to keep the system "fair" and limit chances of untoward manipulation:Reuploaded videos should be tagged as such.There should be some arbitrary limit of change to the video content, ie. 75% of the content should remain unchanged.The original video should still be view-able for context, not directly, but as a sub-link in the new video description somewhere.I do like the idea of having pre/post-roll ads that can be added and changed outside the scope of the video, that can be changed independently of the main video; with an applicable fee charged by YouTube to keep it fair. Seems like a reasonable approach. Should these be able to be ignored, or opted into for those with YouTube Red subscriptions?

content: Completely agree. To other YT creators out there don't underestimate the power of pulling out the salient (or off-beat) point of a video and putting it into a separate shorter video.Even if it seems trivial or silly.An example is the below video of a radio contact with NZ. There's probably 50 or 100 similar videos on my channel. It got just over 1000 views which is normal.The distinctive thing about the above is because signals were poor I resorted to shouting morse code into a microphone (as I had no key with me).Pulling that into a separate (shorter) video with a focused title got double the views, more comments, more likes and it being picked up by others on Twitter.It sounded stupid but apparently people liked watching it

I would like to make these more accessible to others that are not willing or able to read such a long discussion that spans almost 4 years. I have also saved all of the image and link history, along with many screenshots of unique and key aspects of the conversation from the thread. Initially I did this for my own notes as I have been creating a tutorial for YouTube as I build a clone of the project. These details could be very helpful to others but I do not wish to create problems from redirecting traffic away from this site. Are there any objections to the creation of a wiki? Also is there any problem or issue with posting cited or consolidated text from others on this site in a strictly none monotized Creative Commons format?

It might well be a kickstarter.I just recall these where tiny modules, barely larger than a USB plug, and packed with SMDs.

content: When he said "wafer fabs are evil, because they just chop them up and their cheap" @38:00 What did he mean? That might of not been what he said I couldn't hear it well.Won't 8 bit be around until arm comes don to the same price as 8 bit? Also won't 8 bit become MORE popular since things that were running on a specific circuit are now just using a generic micro? For instance I have a clock that instead of using a circuit that makes time and drives displays, they just use a simple micro and program it into to be a clock. I can plug a computer into it and make it something else.

content: Every time you cut the cost of ARM the 8 bit guys can use your old fab to make a smaller, faster 8 bit device on a lot less silicon than the ARM version used, and it will do the job for a lot of things that ARM is overkill for. Think of all those no name 8051 chip clones that are in things like greeting cards, led lights and such, where they use a microprocessor instead of regular jellybean logic gates, simply because the micro will do it, uses the same or less board area ( one package or COB as opposed to 5 SMT packages) and is cheap. Look at Electronupdate, where they put a small cheap mask ROM controller in a sounder to make it beep, simply because the tiny COB can be used in 100 product lines the factory makes with only a different chip, no other change in production methods, and you can make 100 of them before doing a change to the next with almost no gap in production, just remember where you changed the box of dice with Auntie Lo that was picking them out and placing on the dot of epoxy on the riser. 1mm by 1mm chip will do, and cheaper than any ARM core.

content: Dave,First of all thank you for all the excellent videos.As an electrical /electronic engineer I studied in the 80ties but only used my engineer knowledge in project management.Furthermore when only dealing with general management the last 10 years, it is perfect for me to be updated by seeing many of these excellent videos. I have just started some small projects on my own and need to be technology wise updated. Here your videos are perfect - Well done my friend !!!!Two weeks ago I purchased a RIGOL 1054Z and my scope is running 04.04. SP1. BTW A very nice scope indeed.I have been watching your FFT video where you are testing the RIGOL 1054Z FFT. At the RIGOL homepage they have stated that they have improved the FFT with the new Firmware released. Can I ask you to do a short video comparing the new the RIGOL 1000Z FFT Firmware with at a Spectrum Analyzer ?Best regardSharp

content: Yep, Ex series 'ASCO' chassis bolted into a bench case. Not even a new metal chassis used. Not what I was expecting. Microbolometer is standard type fitted to Ex series. Not Lepton core (thank goodness) as that is currently limited to 160 x120 pixels or less. This is a classic case of repurposing a current production item to fill a specialist market role at the lowest possible retooling cost. Hence the little USB extension cable !It would have been better if they had used the Exx chassis as the basis of this unit. Manual focus lens plus touchscreen. A better camera chassis in all respects. Even the Ex chassis could be made manual focus if FLIR had wanted such. It is, after all, just the modification of a plastic lens holder.Video mentions Germanium lens. On these cameras a Calcogenide glass material lens is used as it may be moulded and is cheaper.Fraser

timestamp: March 30, 2017, 08:48:48 pm
content: It's just a small matter of usability. The function works and I use it every time I come here.From my point of view it looks like, when I click themark as readand the read flag is set, there is then another call to my unread replies query, which naturally produces no results, so I am presented with a search results page that is effectively blank. There is no content on that page other than a few links in the forum header, which I will most often click the unread posts link to read any new posts or replies to other forum members posts (I do not know what results if clicking mark as read from this page, however, but the forum index would seem a logical landing page).Maybe the algorithm cannot be modified or is not worth the effort, but just thought I would ask.

In the majority I agree with your view that it hasn't really, and perhaps in a lot of cases, as new fans have started to embrace you, they binge on your back catalog, cherry picking their interests, which also skews their perception.However, I do believe you do less fundamental tutorials. You previously had 'Mailbag Monday', 'Teardown Tuesday' and 'Fundamentals Friday'. Despite the fact that I also agree that removing the regularity naming in the title of these segments, in order not to cause you to have to routine the channel, or give false promises is also a good idea, it denotes the level of routine coverage for these segments. You still have a regular mailbag segment, as well as teadowns left right and centre (which i love BTW), but I cannot remember the last fundamentals episode. Please, please, please, bring them back!

Whe sloped you can't have a pcb all the way trough since the battery compartment collides with your board.Straight you'll have to use the rubber bumpers to cheat a few mm for a full length pcb that can actually contain some stuff.Of you could just buy a larger one. They have 5 sizes iirc.A bopla representative recently visited me and showed me their Bocube series, which is a nice twist to regular plastic boxes. Or aluminum for that matter.
