content: Hello AllI just finished reading a great book that addresses a lot of points of using C++ in embedded system. So I decided to write what is not really a technical article rather than a review of a great book that has the answer to “Should we hate or love C++?”https://atadiat.com/en/e-embedded-c-developers-hate-or-love-cpp/Comments are most welcomed

content: I'd say it depends. For very large project, where realtime and code/RAM size are not of utter importance, I'd say object orientation of C++ might have certain benefits.For small scale applications, low level stuff or very high realtime requirements, I'd personally stay away from C++.One more thing to consider:Any high level language feature creates additional code that makes runtime/memory consumption less predictable, might cause data consistency issues and makes debugging harder.I.e. even in C, things like structs should be handled carefully, as structs can be copied using the "=" operator and passed as as parameters or return values on the stack. So there's a heap of additional code created for something that looks like nothing at all. Now in C++ thinks like operator overloading might make the code look much cleaner but create lots of code on opcode/assembler level that doesn't match the C source. So debugging issues becomes much harder.

From designing the product, prototyping, going to China for production samples and also Crowdfunding.All the journey will be documented on this channel.Among other things, I want to contact Dave to teach me (... I guess, because I am YouTube newbie), how to insert paid ads on his channel to promote my own channel since his audience is my target audience.Cheers Dave, Cheers everyone !!!!http://www.v3channel.com(This linke will re-direct you straight to the YouTube Channel)This is my latest video (Preview of CES 2019):Thank you!!!!PS: I will only post on 3 threads.

content: Quote from: james_s on December 27, 2018, 06:00:04 amThat agrees with my experience. The only way I've been able to update scripts on a Micropython board without an IDE is to cut and paste a Python script that opens the file and writes the desired code into it.I assume that this is how the IDEs do it too, but haven't bothered to investigate. The IDEs just work..I think that for the micro:bit the IDE builds and flashes the full image, including the Micropython firmware - the time it takes suggests that it is flashing more than a few kB of scripts.But nobody trust me on this... I have only dabbled with Micropython.

This applies to both tube and solid state gear from the 30's-60's. Tube amplifiers are especially vulnerable to shortened life due to today's higher working voltage.Posted 11/11/2018

Now we turn our attention to the field coil, which had no other solution but to be rewound. Although I gained some experience in winding an isolation transformer, winding a field coil poses different challenges. In this video I also show how to change an oilite bronze bushing and what I listen to when I have a boring task to do.

content: Two small pointsA. Leaving that much exposed wire on the PCB were you soldered wires into the Pot connections, is a real risk of short circuit.The purple wire is perfectly done, the other two connections are using too thin wire.If you haven't gone back and fixed it, please do, it will make the PSU more reliable.B. That PCB with 4 diodes on is a mess, use pliers to form the diodes to fit better before installing them.Straighten the wires, then bend them 90 degrees over a certain radius to pass thru the PCB.Look up the term "component lead forming"Attached is a cheap lead bending tool I use, official name is "Pro'sKit pk-501D" which may turn up results to suit your location.The generic term for these is "round nose pliers", also used for things like Jewelry Making.

content: Although I understand 10% of what he says (and 1% of his jokes), I've learned a few things from AvE, e.g., how to identify the various kinds of plastique and their application, or what makes some materials (metals) rust (oxidize) and others not, and about mrpete222's channel, of whom I became a fan.At first I didn't like AvE's videos, because he sounded to me like those kids who enjoy destroying things for no apparent reason.His attempt to convert a drill press into a poor-man's mill ( " "IMPOSSIBLE!" Milling Machine from a Drill Press ") changed that. I still laugh every time at 11:16 min.I find his content amusingly informative (translation: he shows what not to do in the shop), even though he occasionally jumps the shark, like at the end of the video down below me.So I decided to tear down a drill of an almost identical model. The difference is that mine was not in a pristine condition as his, had many problems with previous tinkering, and the motivation was to evaluate a possible repair.

Unless you just like to hoard stuff or run a museum.Some older tools do hold their value and are sometimes better than modern equivalents. Those don't include majority of electrical tools.

You can get them from Sourceforge or our site. Reprofiler can now swap profiles between Windows 10 user accounts as well as reattaching to the original.The way of handling packaged apps is non-ideal as it does reduce security, however it's the only approach known to work so far. I have one or two ideas to check-out in this respect.If you're not using Windows 10 there is no specific need to update.http://iwrconsultancy.co.uk/download

content: Hi all,I've been using Vegas since Version 11 and now am up to Vegas Movie Studio 15 Platinum but am now moving to DaVinci Resolve 15 for my own YT channel.The basics of Vegas are fine, the GUI around the actual editing are ok, but I find the text handling and on-screen quality of text a bit rubbish.....always seems blocky around the edges. I notice the same in other folks's YT channels whom use Vegas. Anyways, I'm bored with Vegas......So actually in 2016 I tried Resolve but it didn't support my Panasonic Camcorder AVCHD files, the audio was always empty and since I didn't want to re-encode before importing so I just left it. Roll on 2018 and I thought I'd give it a go again....and surprise they've fixed the issue and I'm liking what I see!Resolve I found very easy to get to grips with and epspecially on a dual monitor setup everything is right there from adding transitions, to text with all the bells n whistles.The keystrokes are obviously a little different but once you have them it's fine.....and I believe you can map them so not impossible to replicate Vegas if you want.My own way of testing Resolve was to build a template with all the functions and toys I'd want to have going forward......and I also did my last YT video in Resolve albeit just the very basics of a video. What I like is that it's very easy to create something like a complex transition but then modify/change it later......there's no getting tied in so far you end up deleting it and starting again.The paid version ($299 I believe) offers a load more features:https://documents.blackmagicdesign.com/DaVinciResolve/20180404-10399d/DaVinci_Resolve_15_Feature_Comparison.pdfPS. There is one bug in Resolve I have reported (and got a reply) involving slide-in style pop-ups from the side, i.e. instead of static text messages on-screen I thought it would be great to see them slide in from the side enclosed in a box kinda thing, then back out again. Turns out everything below that text/graphics that I am sliding in the timeline will slide also! They've acknowledge the issue and so hopefully they will fix with an update soon.New lease of life for me I think!.......But just wondered if anyone else is using DaVinci Resolve and what were your thoughts?Ian.Dual Monitor setup (1920x1080 each):-
