Only Slowman is too stupid to read. He clearly said he just copies circuits out of datasheets. You probably do think that is "designing". It is more than you do.
How's your oscillator coming?

You're clueless. ...and illiterate. He was generalizing.
You're dumb enough to really believe in socialism. You might just as well take credit for it.
You have no ideas, Slowman.
It's not surprising that you haven't been paying attention. You simply demonstrate how illiterate you really are.
You really are an idiot. The above is positive proof. OTOH, perhaps you do believe those dealers can fix the lives of the thirteen (known) who died because of the ignition switch.

Panteltje doesn't design anything. The quality of his design skills may be debatable, but he does seem to be very busy turning his concepts into real ity.
I'm quite enough of designer to know that copying circuits out of data shee ts isn't a safe option. It's a long time since I had to rework the design o n an Analog Devices datasheet into something that could work, but the memor y does stick with me, not least because Analog Devices is one of the better manufacturers.
That krw thinks that this is a strategy that anybody could adopt is yet mor e evidence that he lacks a functional brain (not that there's any shortage of that kind of evidence).
There's been no progress at all, and there probably won't be until I get ac cess to enough bench space to spread out the bits before I start soldering them into the prototyping board I've got (which is currently sitting safely in the die-cast box that will accommodate the whole thing if I ever get ar ound to putting it together). Stage one would probably be putting the mains socket into the side of that box, which would take some drilling and filin g, not to mention taking a bunch of additional stuff out of that box.

I'm about as clueless as I am illiterate (and this is being typed, not spok en).
Jan was generalising, but about a quite specific class of boards designed f or manufacture in low volumes. Your reading comprehension - or rather your lack of it - lead you to try to base an insult on this unexceptionable fact .
I called you on it, and you retreating into your usual cloud of half-witted abuse. Who - in their right mind - would bother typing a message for a gen uinely illiterate recipient?

On the contrary, I'm clever enough to know that socialism and communism are two quite different political philosophies, a level of sophistication quit e beyond right-wing nitwits like you, and giving me credit for a political philosophy that dates back before the 1850's is a trifle unrealistic, even for you.
"reality" is what he knows, which he knows to be absolutely correct, even when it isn't.
I've got rather more ideas than you have, and rather more of them have some basis in reality.
liability is important, guarantee repairs are very expensive, look at the r ecent car recalls for a simple ignition switch.
myth that krw is silly enough to take as gospel.
It's scarcely illiterate to be unable to identify which piece of political trash you were trying to refer to. I do tend to reject the kind of nonsense that you devote your time to propagating.
they were shipped. Getting somebody out to each customer that bought a def ective board is indeed very expensive. Service engineers aren't cheap and n ot everybody is willing to work as a service engineer - the Cambridge Instr uments joke was that the service engineer's tool kit included a do-it-yours elf divorce kit.
Why would I think that? Few production defects kill people, and we were tal king about fixing defects, rather than the consequences of those defects.
Go away and drink a glass or water - if you still can.

Tants are to be used in conjunction with smaller caps, yes. And smaller caps in conjunction with a ground plane, if possible. The ground plane resonates with the ceramic cap at the highest frequency, and the ceramic caps between each other at middle frequencies, but the tant's ESR dampens them all out. If you're allergic to tant, you might use a fat ceramic with a series resistor (which will have better manufacturing tolerances too), but you need to be aware of voltage coefficient and aging if the value is at all critical (e.g., dominant pole on one of those crummy switchers or LDOs).
I'm disappointed by the last test in that link: what should've been done is, two short male pins soldered to the board, and the socket plugged onto it, face down -- not standing proud on more lead length than a wire wrapped assembly!

a bunch of additional stuff out of that box.
SO in other words, it's a failed project and you're just saving the parts for something else?
Jamie
Perhaps the one in the middle of your head. The fact is that *you* said it.

No. The parts - particularly the transformer and the the inductor - are muc h too specialised to be likely to be be recycled.
And the project hasn't failed - it's just gotten tangled up in the move to Australia, and it's on hold until I can get access to more bench-space.

Switch 100 Amps in 50ps for a 1V uP, then figure how much bond wire inductance would be allowed if there was no interleaved capacitance with the logic on chip:-)
Kevin Aylward
His spelling is the least of Jan's defects, but he can still think - rather oddly, admittedly. Krw would be envious, if he knew what thinking was.

Well, most now have separate power and ground for IO and core, usually at a different voltage, but yes.
Though there is likely enough clock skew that they don't all switch in the same 50ps.
