Logic signal display from audio file - Page 1

content: This might be a stupid question or there may be a simple answer but I haven't found one.I'm looking for some utility or software that can read an audio file (Wav or DSD - no FLAC or M3 or other codec) & display the data contents as they would appear on a logic analyser in various output formats (I2S, SPDIF, DSD, etc)I know there are protocol analysers which are part of logic analyser software which interpret & display these formats but that is based on the signals they are receiving - I want to simulate this feed by giving a data file as the input to these analysers, rather than an actual signal feed. Perhaps even just being able to cut & paste hex codes from the data portion of audio files into a protocol analyser would do?It can be done manually but I'm lazy & it requires looking at file contents & converting little endian hex codes into the correct stream of binary data that would be the signal being picked up by logic analysers after playing the audio file through audio device(s)Why I want to do this is so that I can check my digital manipulation of the audio stream is working as it should be. So if I use an audio test file I want to be able to check that the digital signal emerging from various digital chip processing is what it should be. So, for instance how should a 1KHz sine wave appear in an I2S digital stream or in a DSD digital stream?I can edit the data contents of an audio file with a digital pattern that I want to see on the LA output but it means converting the digital pattern into little endian hex codes & editing this into the data area - often getting it wrong - a way of using a binary input into a protocol analyser to check if my digital pattern will output the logic stream I expect in the format chosen - I2S, right justified, left justified, DSD(dsf)Any thought?

I'll get a bench meter for sure next time!There's just too many to choose from! If I like the 289 I think i'll get rid of my 177.....maybe! LOL I started saying that 3 meters ago and still have my 1st purchase! I will "this time" though?!It's so addictive all the test gear, I just want to keep getting more even when I don't really need it. I was even looking at scopes too earlier today!

The last time I used it was 30 years ago when I was not impressed. I even glued the same switch he used and it has not come lose. This is for experimenters that do not have the skills or tools to machine things.If I had not recently used it on switches and meters, I would have laughed. Now I am a believer. I got the small glue gun and glue last month. On some mistakes, I have had to throw the parts away because I could not separate them (cheap Aliexpress stuff).I was trying to build the smallest current meter I could. I got it down to 1 1/2 sq inches using hot glut to fasten the switch and contacts to the meter. I am very happy with the stuff, maybe that is why I liked the video.This might make a good topic - pictures of electronic projects put together using hot glue. If I can remember I will take a picture of some of the things I put together using hot glue. Thanks for mentioning this

It's common for Lithium Polymer packs to be glued down inside phones. This is why Samsung routinely replace the battery just as a standard measure when getting your screen replaced (even if your old battery has nothing wrong with it).

content: On the technical side, THE most important thing is lighting.As for the cameras you will find in smart phones, they are capable of doing reasonably good results, especially when the subject is well lit. If you can keep your mouth reasonably close to the microphone, the audio can be quite reasonable as well.I would suggest you just get your phone and a couple of decent lights and try. See how it turns out and then you will see what you're not happy about.You can then look at the reasons why things aren't the way you want and take steps to improve them. This is, perhaps, THE most important recommendation I could give, as you will learn how things work - or don't work. This will pay huge dividends as you go.By all means come back here and ask questions - and we will do our best to help, but don't start out by looking to spend money on gear you don't know you need.

A sanitarium for the blind, if he keeps playing with that monstrosity.Also, he has zero understanding of magnetrons and waveguide operation. Those styro cups with alfoil lining, are NOT going to form any kind of beam in that topology.That's by far the dumbest, most self-destructive tech-thing I've ever seen anyone do on Youtube. Including that Russian guy messing with magnetrons and tin cans. At least that guy kept some distance. But this... is just inducing technidiots to do the stupidest things - wiring up bare magnetron setups, and harming themselves and bystanders.Well, subscribed.

content: Lol that microwave "gun" is scary. Should have at least used tin cans as the wave guide. Though I think for a proper wave guide the circumfrence needs to be specific according to the wave length. I'm not sure what the rule is, if it has to be half, or 1/4 or what not. It would be interesting to focus the beam in a rather straight line. That is freaking dangerous though, like, super dangerous. Can cause blindness and serious burns.It's perhaps a saving grace that his wave guide did not really work, as the microwaves spread out so the further you are the less dangerous it is.

The conservative ads always said that Justin Trudeau is "just not ready". That was their theme. So when you got a 404 page on their site it said "This page is is Just Not Ready, like Justin Trudeau". Don't recall what the others had, but they all poked fun at the other parties.This one I made is OLD, I suppose I should change it:http://www.iceteks.com/404I need to update that site one day actually. There's some weird encoding issue and lot of characters show up as diamonds, super annoying.

content: Well I was looking at DDR routes and layers used for the Beaglebone Black.I translated the layout from Allegro to Pads Standard.Then did a spreadsheet of the route lengths. Groups of routes matched well.I then said does Pads or Allegro include route lengths through vias.Answer no. That was unexpected.Then I came back to something I have not seen for a long time and could find nothing on the net.Inner package skew listings. When bonding out a ic there used to be skew, inner BGA rows vs outer rows.The BB Black had no adjustment for this. Then I looked at a DDR ic under a microscope.Like most accelerometer and gyro ics, it was not a ic but a circuit board with a ic in it.There were squiggles in the routes to the solder balls that zeroed out the skew.Always learning.

Also the cooling fan is going on more than usual.After opening up Windows Task Manager, I found that always 25% (I have i5 2450, 2core 2.5ghz, 4 threads, so basically 1 CPU is gone) on average of my CPU was always being used and that 'MsMpEng.exe' antimalware was the culprit. My second home PC also has Win7Pro with the same installation of MS Security Essentials, but doesn't have this CPU eating issue. (This system is an AMD Phenom(tm) II x4 955 3.2GHz) Could this be something related to the latest security flaw patches hitting Intel processors worse than AMD processors?How do I fix? Other than disabling MS Security Essentials which make my laptop work like 2 months ago through approximately 2 years ago when I first bought it and began using MS Security Essentials from day 1.

content: Back in the late 90's a place i worked at was going to use an ST Y32NB50 mosfet in the PFC stage of a power supply they were about to manufacture. It is rated 500V 0.12 ohms, 32A IIRC. Ended up using a Y34NB50 instead which has very similar specs but a shade faster I think, I brought home about 75 unwanted samples and of course I have only used two... Nowadays you look up this part on the web and there is only a handful of references and they are pretty much all on AliBaba and with no stock anyway. No datasheets either. What's the go with these things???
