But where will our future engineers come from if there were no decent jobs for engineers any more?

You probably know the answer. There is no lack of poor countries full of young people dying to move up the social ladder. For them, our crap jobs will be a godsend.

I'm all for cutting the wires to the EU.  That's a pretty good way to prevent uploading copyrighted material.

In some ways this is already happening.  I think we had a thread a couple of weeks ago about DigiKey (?) sending EU visitors to an essentially blank page with some text saying "We can't work with you" or something like that.

Tooki's assertion that the cars most commonly stolen are stolen to be parted out is true, at least here in the US. "Chop shops" are a real thing; a stolen car will be brought to one and parted out in a couple of hours.

And consider this: a stolen car, reported to the authorities as such, cannot be registered, which means it cannot be sold nor can it be driven on public roads. If there's no buyer for the car, there's not much in it for the thief.


I don't know where your numbers come from but in my neighborhood, stolen cars are usually recovered a few miles away.  Strictly joy riding.

The high dollar cars may be parted out but that's a minority.  Sure, park your Ferrari in the driveway overnight and it will be in parts by sunrise.  A Toyota Camry, not so much!

Another thing about parting out, we have legitimate salvage yards so if you need some expensive part of a car, all you have to do is go take it off a scrapped car and pay the lady.

One thing that gets stolen all the time is the catalytic converter.  It's so bad that the police agencies have public fairs where they etch ID into the converters.  This is a really big deal and happens fairly often.  There is no VIN on the converter.  It helps if they are welded to the exhaust pipes but they aren't.

As to driving on public roads, steal plates from a similar car.  Or don't worry about it, the cops have bigger issues.  Yes, they will stop suspected stolen cars (that's one way they are recovered) but just holding down the gunfire keeps them pretty busy.  The thing is, there's no real penalty from 10851's as they are called around here.  It's usually a non-violent crime so even when convicted, there won't be any incarceration.  We have to have space for the violent offenders and the Governor's kicking felons loose by the thousands.

It's all joy rides.

And someone in another college only has UK citizens as colleagues and using your method comes to the conclusion that 100% of grads are UK citizens...
Maybe you should think about your methodology.
I think third-graders in china can do it better..

The numbers he gave are obviously biased and the real ones are publicly unknown, but I can confirm the trend (even though not quite as drastic) in a lot of western countries.

And for simple reasons. Engineering jobs are just not attractive anymore to young people raised in western countries. First because engineering is not seen as "cool" anymore. It mostly passes as geeky. That's a cultural trend, a global disinterest for technics as technology becomes ubiquitous. And to most of them, the potential jobs sound boring, unfulfilling and increasingly badly paid.

Beginners / Re: How to select a PTCC and TVS combo?
« Last post by floobydust on Today at 12:30:16 pm »
A naked TVS will get killed by typical automotive transients, due to the energy.
The only TVS I know of that can withstand (12V) ISO7637-2 including load-dump is the massive Vishay SM8A27 TVS 6600W.

A smaller, low cost approach is to have some series resistance upstream of the TVS. This could be from a resistor, diode, polyfuse or regular fuse - or any combination of these.
I wouldn't use a uni-directional TVS here, as -ve going transients will damage your vreg. A 1kV series-diode works and adds some series resistance help to limit spike current to the TVS.

edit: ensure your MLCC capacitors are oversized, as over temperature and with their voltage coefficient they can end up being much smaller and the LDO goes unstable.
Also note TVS's have a large temperature coefficient, so a 20V TVS could have high leakage current at 14V in cold weather.

It doesn't work after that error. Whenever you try to read some MCU, it will always give ID check error. And will read gibberish if you ignore error. Tried rebooting disconnecting, restarting everything. Tried to read multiple controllers (PICs and ATMEL's) - same ID check error everywhere.

I then reverted it all back to v6.71 - both PC software and firmware, keeping it kept firmware at "A" version though. And it all works now, with same MCUs I tried before - they now ID'd and read just fine.

There is even a V8.05 version out now:

http://www.autoelectric.cn/en/tl866_main.html

But it lists the changelog as well and I don't need it at the moment, just a few PICs that were added could be interesting someday, but I have a PICkit3 for this.

And the webpage says "TL866CS/A programmer has ceased production.". Maybe this is the reason that it is not compatible anymore? Or is it the fight with Radioman and then inadvertently introducing bugs? This would be bad.

Those 8.x versions are for TL866-II hardware. The latest version for TL866CS/A is 6.8.5. It is a bit lower on that page, there is a separate section with the software for the non-II versions of the programmer.

YouTube CEO Susan Wojcicki in her latest letter to creators has warned that the EU copywrite directive 13 could force them to restrict uploads to companies only because of the onerous requirement for them to scan all material for copyrighted content and the risk of missing some.

Another option is to restrict the content that EU viewers can access.

https://www.engadget.com/2018/10/22/youtube-ceo-susan-wojcicki-eu-copyright-law-threatens-creators/

Don't know how serious this is or if it is just posturing/scaremongerig as part of their attempts to get the directive modified.

How does one download PDF catalogues from RS and Element14 in Australia without wasting any more time than I already have this morning    |O :horse:

I was going to comment at this post from 2013 but it appeared geared for the UK members, hence this post.
eevblog.com/forum/chat/how-to-get-a-catalogue-from-rs/msg243789/#msg243789

Caution: You are entering a Mini-Rant Zone below    >:D

Jaycar, Altronics and Radio Parts 2018 PDFs were easy peasy to find and download,  :clap:
without any join up BS, labyrinth web site to plough through, Chat popups, 404 pages, browser security alerts  :scared: :bullshit:, website expiry date BS notices etc etc etc   ::)

One might assume Jaycar, Altronics and Radio Parts are a bit more serious about staying in business long term,
and value the odd stray cash buyer, electronics noobs, pros, tradies, DIYers and returned customers back to the electronics industry.

Is it possible RS and Element14 are that well off they can afford to snob out on aussie electronics battlers, and or employing clueless website handlers?


ooops, wait a minute, do RS and Element14 even have PDF catalogues, or is it still hard copy door stops and CD frisbees ??

Could you take a look at the ROCm "HIP" and related work,  (AMD open source cross-compiler allowing work with Cuda code on AMD HW) effort and let me know what you think of the viability of their approach?

Just a quick look.

https://github.com/ROCm-Developer-Tools/HIP

also https://gpuopen.com and https://rocm.github.io/

My current HW (older 6 core AMD "bulldozer" board lacking PCIe 3 atomics support) doesn't support it now.. My GPU which is a Polaris/Ellsmere type would now if I had a newer (Ryzen/Epyx or newer Intel-based) MB and CPU but its my understanding that future revisions of their code 'may' (or may not)

I get the impression it may even work now but if so I am on my own and its totally unsupported.

I cant afford to damage anything so I am waiting to try it until they say they can get it running properly, or I will just buy another GPU and MB once I know I need it and have outgrown everything I have now (I'm not even close, I am just feeling the waters now and don't know practically anything).

I just want to know your opinion on the viability of doing what they are doing and running Cuda code on it. Note that Ive used several different similar programs to run simple Cuda programs and its worked for some but not all of them. gpuocelot - two years ago I had it running and it worked, and I successfully ran cuda test programs on it. I forget what hung me up, something did though. It wasn't a complete tool. And now its a dead project without any support.

None of the similar tools quite work now, none are viable for anything complex though, and gpuocelot is really old and broken- it no longer compiles for me now.

Well a problem you will get is that the microphone may couple electrical fields through its wiring rather then just the acoustic signal if you use something like a spark.

I shielded the crap out of one of those microphones on a stick to make a pockey probe rod (its some where in the coppercone posts I think).

Also with those mics, some vendors sell the standard ones rated till 40KHz (rather then the 20 on digikey)

I have yet to buy the broadband ones.. but I do have some 'ultrasonic transducers' from ebay, the standard type that look like a little dish under a mesh screen. I think if you connect them to a function generator they produce some noise, and they can receive noise too.
