So what is your position, jackass? Are you a trumptarded dipshit
gonna dis the man? Or credit him with being four orders of magnitude
more intelligent than the dangerous buffoon retards like you helped
put in our nation's highest office? Which is it, Trumpanzee punk?

Do you know what he engineered and made his money on BEFORE he
became an investment mogul?

He engineered the terminals ALL of Wall Street used for two
decades.

He got rich the same way Perot did. By hard work.

Maybe engineers do not make ideal presidents. It's much
better to choose former actors, peanut farmers, or rich
boorish TV show hosts. Face it, most voters are idiots.

You must not have read the article. That peanut farmer was a Navy

Welderson is a fucking retard. He is not an 'american thinker',
the dumb fucktard is a NON thinker.

"Engineers make bad presidents."


The guy could not be more retarded to make such abroad
generalization.

And that is only as far as I got with this stupid fuck's 'article'
so far.

Wow... he writes well. Says he was an engineer once. How quaint.

Still stupid to presume that engineers do not know how to lead.
Very stupid.

Yeah, I don't want a rare hamburger. medium is good. And the
right amount of grease. With a good burger, grease should leak out
and run down your arm as you bite into it. I guess everyone can
cook what they want on their barbeque (why is there no q in there?)

I made this chicken pot pie last night.
Three chicken thighs, but you peel off the skin and fry that
up crispy.. and for the fat to cook the rest of it in.
(chicken skin ~ bacon)
Then this puff pastry on top and into the oven.
It was great.

If we are going to be OT.. then it should be about important things.

Engineering is OT here? Yes, it mostly is.

Oh.. so here's a thing.
What's the best way to make some modular circuits that you can hook up
in different ways?

There are all sorts of 'crates' and (well you sell to that market.)

But the 'crates' are spendy, and give you constraints.

So (at least for myself and home lab) I've been thinking of
using aluminum U-chan. to make project/ circuit boxes.
(more me these would be mostly analog.. )
(input on one side, controls on the top/ (or bottom of
open pcb.) I'm thinking of switches/ pot's mounted to the
top side.) and output on the third side. (power-in maybe
on the output side*.)
Any thought? The other 'standard' project box is five
sided with a lid. And you either build things on the lid
(limited area) or build it inside the box.. limited access.

1 foot of 2" deep by 4" wide U-chan is ~$18 on McM-C

*Speaking of power in, (and giving full cred to Phil H.) I was
thinking of standardizing on 24V (dc)

Yup. The old-fashioned 44-pin card edge connector still works, but with
bare boards you have to use modular shields over sensitive (or noisy)
stuff. BITD Tek 500-series modules used similar 80-pin connectors iirc.

Who's going to be doing the hooking up? If it's students, I really like
metal-body BNCs. They're far more durable than SMBs or SMAs. For
sending analogue signals between boards, we often use U.FL (UMCC) coax
connections, which are cheap, good, and small.

Any thought? The other 'standard' project box is five
sided with a lid. And you either build things on the lid
(limited area) or build it inside the box.. limited access.

Most of our recent stuff is pretty well miniaturized, so we use FFC
jumpers between boards. Our most recent design uses a 12 x 15 mm board
mounted on a TEC, communicating with the front end over one of these
really neat Molex polyimide FFCs,
<https://www.digikey.com/short/zq4t1p>.

We're running a 12-GHz f_max SAV-551+ pHEMT to bootstrap a 1000-pF MPPC
across the FFC, with a quad-SPST mux inside the bootstrap loop. Insane,
but it works like the bomb. (No, not at 12 GHz.)

1 foot of 2" deep by 4" wide U-chan is ~$18 on McM-C

*Speaking of power in, (and giving full cred to Phil H.) I was

Yeah, higher voltage supplies make things easier, except that if you're
making high current low voltage rails (e.g. our class-H TEC driver) you
sometimes need to step down to an intermediate voltage. (It isn't too
efficient using an async buck to make 1.3 volts at 3 amps.)

I just sort of invented a spin on my Dremel prototypes. The idea is to
make little adapters with mouse-bite connections. They can be single
tiny parts, or later on, functional circuits. A standard geometry
would open up possibilities for the carrier board.

I sawed up some Bellin adapters to make them mouse-bites

I could lay out a panel of various adapters for tiny parts, and have
the bites routed by the fab house.

I'm in some other world, thinking of DIP opamps and mechanical switches.

I guess I dream of circuits that could be kits,
and kids could build and hack,
through hole. (SMD' could be on little pcb's with solder pads?)

Digi-Key has those - so you can replace obsolete lead version ICs with
SMD versions that you solder to these boards:

Huh, you really don't like Bloomberg for some reason?

I posted a link about engineers, something that is rare in the popular
press. I expressed no opinions.
Huh, OK I read the first bit and it looked mostly like a political
hit piece. bloom ~ carter ~ hoover.
Was there any useful engineering in there?

Hey did you know you that all hamburgers in Canada have to be well done?
https://nationalpost.com/news/canada/medium-rare-burgers-are-taboo-in-canada-but-may-not-be-as-perilous-as-thought

I can get whatever I want here. I do like it a little warm inside.
Yeah, I don't want a rare hamburger. medium is good. And the
right amount of grease. With a good burger, grease should leak out
and run down your arm as you bite into it. I guess everyone can
cook what they want on their barbeque (why is there no q in there?)

I made this chicken pot pie last night.
Three chicken thighs, but you peel off the skin and fry that
up crispy.. and for the fat to cook the rest of it in.
(chicken skin ~ bacon)
Then this puff pastry on top and into the oven.
It was great.



If we are going to be OT.. then it should be about important things.

Engineering is OT here? Yes, it mostly is.

Oh.. so here's a thing.
What's the best way to make some modular circuits that you can hook up
in different ways?

There are all sorts of 'crates' and (well you sell to that market.)

But the 'crates' are spendy, and give you constraints.



So (at least for myself and home lab) I've been thinking of
using aluminum U-chan. to make project/ circuit boxes.
(more me these would be mostly analog.. )
(input on one side, controls on the top/ (or bottom of
open pcb.) I'm thinking of switches/ pot's mounted to the
top side.) and output on the third side. (power-in maybe
on the output side*.)

Yup. The old-fashioned 44-pin card edge connector still works, but with
bare boards you have to use modular shields over sensitive (or noisy)
stuff. BITD Tek 500-series modules used similar 80-pin connectors iirc.

Who's going to be doing the hooking up? If it's students, I really like
metal-body BNCs. They're far more durable than SMBs or SMAs. For
sending analogue signals between boards, we often use U.FL (UMCC) coax
connections, which are cheap, good, and small.
Huh I've seen the "U.FL (UMCC) coax" but never used it.

>
Yeah BNC's on the ends and a pcb floating on stand-offs
and switch stuff from the top.

Any thought? The other 'standard' project box is five
sided with a lid. And you either build things on the lid
(limited area) or build it inside the box.. limited access.

Most of our recent stuff is pretty well miniaturized, so we use FFC
jumpers between boards. Our most recent design uses a 12 x 15 mm board
mounted on a TEC, communicating with the front end over one of these
really neat Molex polyimide FFCs,
https://www.digikey.com/short/zq4t1p>.

Yeah I'm not expecting to sell anything to you.
For myself.. I just need a few of the gain and filter circuits
I left behind. X10/100 gain stage 1 k ohm in BW- 1-10 MHz,
so two inverting stages, with some pads for caps
across FB R if needed.

And a nice SV (state variable) filter.

We're running a 12-GHz f_max SAV-551+ pHEMT to bootstrap a 1000-pF MPPC
across the FFC, with a quad-SPST mux inside the bootstrap loop. Insane,
but it works like the bomb. (No, not at 12 GHz.)

Right.. I'm thinking 10MHz max. :^)
(There are some way cool GHz modulation of laser diodes that I'd
love to do some day.)

1 foot of 2" deep by 4" wide U-chan is ~$18 on McM-C

*Speaking of power in, (and giving full cred to Phil H.) I was
thinking of standardizing on 24V (dc)

Yeah, higher voltage supplies make things easier, except that if you're
making high current low voltage rails (e.g. our class-H TEC driver) you
sometimes need to step down to an intermediate voltage. (It isn't too
efficient using an async buck to make 1.3 volts at 3 amps.)

OK So I was thinking 24V for the intermediate stages.
Input (preamp and detectors) and output can be different.

Cheers

Maybe engineers do not make ideal presidents. It's much
better to choose former actors, peanut farmers, or rich
boorish TV show hosts. Face it, most voters are idiots.

Right-wing engineers are highly predictable. If society was entirely
composed of right-wing engineers governance would be easy.

I just sort of invented a spin on my Dremel prototypes. The idea is to
make little adapters with mouse-bite connections. They can be single
tiny parts, or later on, functional circuits. A standard geometry
would open up possibilities for the carrier board.

I sawed up some Bellin adapters to make them mouse-bites

https://www.dropbox.com/s/i5o7ie33xe8ibpt/Z474_Partial.jpg?raw=1

Here's a pulse generator output stage, as a mouse-bite component.

https://www.dropbox.com/s/w9ax8q9u00obnx4/T577_Glob_2.jpg?raw=1


I could lay out a panel of various adapters for tiny parts, and have
the bites routed by the fab house.

I'm in some other world, thinking of DIP opamps and mechanical switches.

I guess I dream of circuits that could be kits,
and kids could build and hack,
through hole. (SMD' could be on little pcb's with solder pads?)

Wow... he writes well. Says he was an engineer once. How quaint.

Still stupid to presume that engineers do not know how to lead.
Very stupid.

Bloomberg would make a poor President primarily for the same reason
Trump does - he's a deeply out-of-touch billionaire who only knows how
to work for cronies.

The reason why Trump succeeded where B will fail is Trump is much better
at acting the role of "man of the people" while he busily sells them out
or at best, does little to nothing of real benefit for them.

At least well enough to sell wingnut nitwits on that idea. It's not a
high bar. On matters of actual policy/substance Trump is a pretty
bog-standard Republican, nothing new to see here.

He seems to reserve his biggest "tyrant" moves for members of his own
party who won't keep in line or are expendable. Tough break.

** Never come across Mr Welderson before - seems like an expert essay writer. I checked some of his other works in the link - re abortion and "chicken little".

IMO he "engineers" readable and entertaining essays, long enough to say something while short enough not to bore.

I think he has some pretty good insights and is smarter then the average bear.
