hi folks, we now have #community-bots for interacting with bots
dusty citrus
Good! We now have an area for those tinkerers out there. Maybe you could pin this link to #community-bots for people to get started:

@fickle slate #general-tech is for non specific topics that don't have a definite channel, the way I think of it.
Whereas #general-chat is clearly for what is off topic .. each individual brings their own sense to that notion.
My joke is to say I was off topic in #general-chat !
So since we don't have a #prototyping chan I would choose to bring an electronic project prototyping discussion to #general-tech (which was one of the first channels, here).
That's hardly offtopic, so it doesn't go in #general-chat in my view. ;)
I reserve #help-with-projects for those asking questions (or asking for help) as a starting point for differentiation between it and #general-tech - I try to look at it from the point of view of someone who hasn't visited here before.
On pretty much every message base (forum) I've visited the equivalent of a #general-tech exists .. and has the highest posting (message count) statistics (usually) of any of the available categories.
I think that says a lot. ;)
Those places often have an equivalent of #general-chat as well. ;)

@fickle slate If you're asking about the 1-2-3 rule gif, it's updated during hurricane season. I think I've seen it updated a few times outside that season. During the season, I think it's a six hourly product.
It used to say when it will be issued again during the offseason. I don't know why it doesn't this year. It's a very old product so it may not be receiving the same attention it once did.
This is a nice telltale for our current weather regime:

The Telemarketing call that just came in reminded me of another thing I do when they phone.

I've had Honeybee Democracy on a Kindle e-reader and had forgotten to get back to reading it.
Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building.
Even if they are taken (in aggregate, per colony) as a kind of biological 'machine' that is (or is more than) the sum of the parts - no individual very 'intelligent' - it is remarkable simply over the distances at which they 'operate' and to the size of the individual 'brain' (don't know what they have).
Certainly, they are 'alive' in every sense of the term.

On average, how many people has a carbon atom that I breathe in already been through?
HMMM
fickle slate
well one answer to the thought experiment goes like "there are more atoms in a cup of water then cups of water in the sea"
(or i guess, more atoms in a breath of air then breaths of air in the atmosphere?)
Although not sure how well it mixes together
dusty citrus
4.9x10^22 liters of air in the atmosphere, roughly calculated
About 0.5 liters per breath of air
9.8x10^21 breaths of air in the atmosphere
There are about 2.69 x 10^22 molecules of air per liter
1.345 x 10^22 molecules in a breath
It appears you're roughly correct :P
And that's molecules, not even atoms, dang

@vital harness I just downloaded it, I'll give it a go this weekend 🙂

@high galleon currently it would return tails on tie, i was gana rewrite to reroll on tie but the coinflip part of this code already takes a little bit of time to execute
you will know if it was a tie though because it tells you how many heads you got out of 1000
high galleon
a good solution could be to flip an odd number. 999 = no way to tie 🙂
fickle slate
^
also if heads > 500: side = 'Heads' if heads < 501: side = 'Tails'
triggers me
like first you can do heads <= 500 instead of heads < 501, and second you can just use an else 😛
you can also use a for loop and do heads += random.randint(0, 1) to make code look neater. (But that doesnt matter really, I just found the if heads > 500: statement confusing)

I bought 10 of these 30w 110v AC COB grow lights, it said it needs a heat sink so i got some 40mm X 40mm but it still gets too hot... anyone have a link to some resistors rated for 110v 30w? I've fried so many of my tiny ones... I was able to take two of the same large ones off something but it makes the two lights too dim.. like less then 20% normal... I need different resistors. The two same large resistor i found don't get hot and the COB produces like zero heat, no need for heat sink now.
native cedar
Try a 10k 10W cement resistor to start with, measure the voltage drop across the resistor and that should give you more data. But how to set it up should be in the spec sheet for the LED.
All resistors have a maximum power disspation.
Watts = Volts * Amps
Amps = Volts / Resistance.
So if you have 110V running over a 1k resistor you'll be running 0.11A using 110*0.11=12W.
Those tiny resistors are rated for 0.1W so they catch fire if you put 12W across them 😉
(I'm assuming the voltage drop for the LED unit is 1.5v - I don't know that's true) but
voltage drop of Resistor = 110 - "voltage drop of LED unit"
idle iron
@native cedar thank you for info. this is where i bought them from https://www.aliexpress.com/item/4000360683003.html?spm=a2g0s.9042311.0.0.52c74c4d8H4TtM
i dont see much for specs other then "Power Tolerance: 3%"
native cedar
i see; so basically it has an on-board driver and expects that it's connected directly to the mains
idle iron
yes... it makes tons of heat though that way
native cedar
yes; so what you need is a 50W heatsink and thermal paste 🙂
idle iron
my thermal glue never came from china 😣 , think the coronavirus did something to the flight
i got a few larger GPU heat sinks i was gana try though but no paste
native cedar
you need the paste for effective heat transfer
idle iron
for sure
native cedar
as for putting this in safely.
idle iron
AC doesnt scare me as much as when i was a kid... been shocked many times and my heart still working
supposedly more people die from 110v then 220v just because its more common
native cedar
as for dimming it: for AC voltage with LEDs you need a trailing edge dimmer.
you can't just shove in a resistor 😉
you could get a step down transformer to lower the voltage; but that might mess up the onboard controller if it's expecting 110vac
dusty citrus
I got a FPGA! Time for CPU development!
But I will start with something simple first
late fulcrum
Erf, wait states don't really work for realtime use like that.
Wait, where do you get RAM that slow? I thought your pixel clock was like 10MHz?
fickle slate
4 cycles of FPGA time @late fulcrum
which runs at 50mhz
What I meant is like
I am thinking about building a CPU, but ram access time makes things wack
late fulcrum
With a CPU, you can generally stall fetches with wait cycles if you have to. I considered doing that when running a CPU using FRAM as RAM, then realized I could just clock the CPU at 8MHz and wouldn't need wait states (I didn't need top speed for that project, power saving was more important)
fickle slate
yea
I was thinking about pipelining the fetches so that by the time an instruction finishes executing, the next one is loaded already
late fulcrum
That would be cool, but more intricate.
lapis bluff
@fickle slate and when prefetching instructions you need additional states to handle branches, where the next instruction you want is not the next address.
late fulcrum
But watch out for Spectre and Meltdown
fickle slate
@lapis bluff good point, JP would have to reset prefetched instruction to NOP
(at least that's one way to handle it)
late fulcrum
The old fashioned approach is to just clear the pipeline and start fetching anew after the branch. This is fairly simple to implement and works reasonably well. Assembly programmers knew this and would arrange their loops so the default branch was the common one. One of the performance improvements that came with early compiler optimizers was to do the same thing.
trail vortex
I am looking for makers interested in trying/experimenting with a small board which implements a full Hardware Security Module (asymmetric/symmetric encryption, TRNG, keys gen, storage, etc). It is all in hardware inside an FPGA (MAX10 at 100 MHz) and you can connect via SPI with the provided Linux API (now tested under RPi) via CLI. Soon also compiled lib for Linux and later for Arduino. Now creating some tutorial on how to encrypt and send end2end encrypted data, you can do all you want with it.
Anyone interested? More info at http://bit.ly/2HmeM0c
@fickle slate check the J1 forth CPU, pretty cool 😉

I'm curious, but unsure how you'd implement a TRNG with an FPGA (I've read fairly convincing papers claiming it was impractical)

There are many ways, e.g. via ring oscillators.

sick adder
@trail vortex interesting presentation, thanks for the link! I used a LFSR to whiten avalanche noise in a AVR/Arduino TRNG project years ago. I don't follow what advantage comes from using both galois and fibonnaci LFSRs, but I can see why they would both offer better characteristics than the simple ring oscillator. It felt like quite a feat to generate 2Mb/s (128KiB/s) of random data on an 8-bit microcontroller.
40 samples of the physical noise source in -> 16 bits of random noise out, iirc. there was a nice "knob" to turn depending on how correlated you thought the input noise was. I found some input-to-output ratio that would pass dieharder tests and doubled it, iirc.
(these days I tend to believe a very modest number of truly random bits plus a CSPRNG are reasonable to trust...)
pearl vigil
Has anyone else been having issues getting custom PCBs from china due to the virus? PCBWay times from 2 days to 15, $5 for 5 to $53 and only in green
trail vortex
Thank you @sick adder , that is indeed an interesting and delicate topic. We have also some work going on to add a new TRNG module for more mission critical applications. It is very fascinating to be able to provide all those encryption functions to any maker/DIY enthusiast. It is extremely easy to connect via SPI and implement e.g. an ECIES hybrid encryption scheme using the API. I will soon post some material about it. All the comments are very appreciated and welcome.

i am wondering what i should do for feeders for my diy pick and place machine
fickle slate
Cool I was thinking about this ^
shrewd hatch
building a pnp machine is a good idea if you want to be able to do your own pcb's from start to finish
late fulcrum
Hmm, feeders seem fairly simple at first glance: something to advance the reel, some structure to guide the parts in a groove and peel off the covering. You'd want to decide if you want sprocket feed (accurate, but needs different sprockets for each pitch) or pinch roller feed (easy, but less accurate), and how you want to advance it, possibly steppers or DC motors + encoders.
As ever, the details are where the hard problems hide.
shrewd hatch
@late fulcrum if i am right the holes on a smt tape are standard spacing so its more a matter of how to accurately feed parts and pull back the top film
late fulcrum
I wouldn't be surprised if there were just a few (or just one) sprocket hole spacing, but I didn't know. Given that, accurate feeding is just a matter of rotating the sprocket by known amounts (I'm thinking of pull vs push for easier mechanics)
I figure pulling off the film could be done with either a simple splitter blade, or a tensioned take-up reel, or a combination
Might even be able to combine the functions by having a roller/sprocket on the top (film) side, that advances the carrier and simultaneously peels off the film (there would be a separation roller to keep the carrier going forward separately.
shrewd hatch
the channel from the above video also has a video on there feeder design (still not done) but it does have some good points

finite horizon
dusty citrus
What the heck...
I really just don’t get it
An explanation of the event horizon of a black hole states that it is absolutely impossible to escape, because the gravity in the zone has destroyed conventional space time to the point where moving in the opposite direction to the singularity becomes the same thing as moving towards it
That’s cool and all, but someone explain this to a 9th grader ;-;
What is space?
How is this possible?
crystal ore
The conventional explanation is to think of space as kind of elastic. Gravitational masses "stretch" it in their vicinity, slightly changing the distance between point A and point B. That does things like change what "going straight" means, so you get things like planetary orbits and gravitational lensing of light.
The black hole event horizon is the most extreme example of this, where things stretch so much that they sort of break.
dusty citrus
Oh my gosh...
crystal ore
Bonus: it also stretches time, changing how long it takes to go from event A to event B. We're all aging ever so slightly slower on Earth than we would out in space, because we live inside its gravity.
dusty citrus
This is relativity, right?
crystal ore
Yep. Special relativity deals with things going fast, and general relativity is a more complete theory that also incorporates gravity.
finite horizon
But time isnt a real thing
The only thing aging us is the loss of the telomeres at the ends of our DNA

Andromeda Paradox:

I think Penrose was saying 'consider this' not 'this is how things are'.

I wonder why exactly COVID-19 is being so rough on China. I see that it’s spread to other countries such as the US, and Australia. But people only talk about it hurting China. Its symptoms are super mild. I don’t see myself passing away from a runny nose and mild cough here in the US. Is China just handling it badly due to population?
high galleon
ppl die from the flu (in the US too). and this one kills more old and very old people. 3% death rate for general pop. is not so bad, but it's higher for ppl > 64 yo and much higher for > 80 yo

Is China’s demography older than most, then?

3% of the global population today is 250million.

Not even close to Ebola’s death toll

so the concern is that if it spreads to everyone, it's still going to be a big death toll, even if you yourself are probobly not going to die
dusty citrus
Hmmm.. so this isn’t too, too bad
So it affects older people worse due to it being a respiratory illness, but that doesn’t differentiate China from the US very much, for example. 76 vs 79 life expectancy
If it spreads to the same level in the US, will it be as bad as it is in China?
fickle slate
probobly not?

I don’t know for sure, but China’s population control challenge must be making it more difficult to handle

There is a single solution; Make greed a capital crime, rewrite all the laws to be "for the good of all" and outlaw ownership of invention; eg make everything open source.
ofc no one is going to do that because everyone in higher up politics is a greedy as sin.
fickle slate
Humans have the right to be gready
Do you think the farmer grows you wheet due to his own benevolence?
No, he grows it because he is gready, and can profit from the wheet.
Not sure if this server has a role against politics though hence why I dont want to get into it. (Though this is economics not politics in my opinion)
But in economic theory people do stuff for their own greed, and transactions happen when two people can profit off of it
native cedar
"economic theory" is a narative not objective truth; we don't have to do things that way.

What do you suggest?
Drugs take billions of dollars to RnD
Wheet takes effort to grow
Oil take money to extract etc
native cedar
sure, but they've known since 1930 that there's something in western food that makes humans sick. and that gets ZERO RnD.
native cedar
no;I mean - why do we have dentists? it's because the food we eat makes our teeth bad.
the native unwesternised cultures that eat unproccessed naturally occurring food don't have teeth problems.
so rather than find out the cause, they create an industry to "fix" bad teeth.
fickle slate
Certain cultures have better teeth because 1) they eat more meat which strengthens the teeth 2) they eat very little suger
And no one "created" the industry of dentists. Someone had bad teeth, and someone else had an idea for how to make them better
First person was greedy by wanting better teeth, second person was greedy by wanting money, ergo transaction happens
(The only source of suger in the old world is honey iirc) (not counting suger in fruits)
Hence why the ancients where so into bee keeping
native cedar
I think you misunderstand the concept of greed.
Two people transacting for mutual benefit isn't greedy; it's good practice.
Greed is transacting for the benefit of self to the detrement of others.
fickle slate
(Virgil himself wrote an entire poem about bee keeping)
Everyone values different things differently
So a farmer values money above wheet
And you value bread above money
So you buy some bread

I'm pretty sure farmers value making food for the population; otherwise they wouldn't farm.

In each person's mind they come out on top
No they dont
They value 1 thing: money
Everything else is secondary
Sure 1 in 100 people would work out of benevolence
But if for some reason farmers stopped making profit they would stop farming
native cedar
there's nothing wrong with being profitable

Been struggling with this, I have been working in automation software and embedded systems development. And I can't help but think of how many jobs I'm destroying, anyone else in industry have that feeling?
late fulcrum
I don't think of it as destroying jobs, but as replacing boring jobs with more interesting ones. The cotton gin removed the need for a lot of people to manually pull seeds out of cotton, but increased production enough to let a lot of people work as weavers, dyers, tailors, etc. Automation also gave us the 5-day (soon to be 4-day) work week, idle time, disposable income, etc. There's no intrinsic necessity for people to give up large chunks of their lives working for someone else.
sick adder
a friend's 3d printing fail
@karmic kite one positive thing to do is work for social change around this issue, in a way that is in agreement with your values. I am not sure how to phrase it without being totally political, but what if we lived in a society where we thought of automation as "creating leisure" instead of "destroying jobs". But it requires our public institutions to treat the whole situation differently, and that requires people at large to perceive the situation differently.
grave crest
Hmm. Forbidden cotton candy.
covert spire
Sorry to be a bit blunt, and possible because I see the part of society that isn't online or represented online. "Creating leisure" hasn't paid certain people's bills. Granted Cotton gin has helped farming, bit on flip note, also created a demand for faster weaving equipment, so many of cotton pickers ended up working on said machines which was lesser safe environment conditions. While sunburnt may seem bad, having a limb destroyed by unguarded machine was still worse. Not everyone has the fortune to go to college & get degrees in some field to work decent paying jobs.
Then again, I'm waiting for automated trucks to become more common because of how inhumane trucking industry has become.
late fulcrum
Paying bills is actually a separable problem (although the 1% don't want us to know that). Job safety is also a separable problem, but the general case is that when people change jobs, the parameters (safety, satisfaction, engagement, effort, etc.) also change, some better, some worse.
College in the United States is basically a scam these days.
covert spire
My point entirely is people complain about their job in certain industries, yet example of trucking where labour laws haven't been applied, so pay isn't compensated for minimum wage. Also while there are regulations forcing cost to rise, none of the regulations do anything to help safety, but instead hinder it.
While separate problems, none are being addressed.
Colleges' scam is a separate problem also.
dusty citrus
To replace a job without retraining the person who once held that job .. is ______.
To ask all persons who once held jobs now done by automation, to retrain, is ______.
It should be perfectly obvious that some jobs, once taken away, are the very last jobs that worker will be doing .. whereas they may've been working for n years beyond that day, had the job not been taken away (by any agency what-so-ever).
they are taking our jobs is often heard.
Doesn't entirely matter what the they is in that sentence.
all I got left is Petco one might remark, after having lost their job in that small town.
covert spire
That reminds me of the discussions of when large corporate retail was pressuring out small locally owned businesses with the claim "We employ more" to now utilising self check outs. When something is created to remove demand of certain job. The job title & description is removed, therefore you're forcing person to either find new industry or to adapt to new job demand in the same industry. While per claim of removing job seems to be debated, you're none the less taking work experience which is demanded for regardless & made it worthless.

Normally the floor doesn't have a charge, but some floors can conduct electricity, generally to ground.

If I have a neutral cap, and put a leg on the floor, will it end up statically positive?
fickle slate
no

Oh, wait a minute. That’s not how caps work
But you’re telling me that electrons in the cap wouldn’t leave?

if both the ground and cap are "neutral" why would the leave?

Sorry, I'm a little confused
I meant neutral as in "equal amount of negative and positive charge"

10-20 mA is strong enough to override electrical signals from your nerves
By 30 mA any muscles controlled by the affected nerves are no longer under your control

We were taught to work one-handed. They literally said to put one hand in a pocket, but we just worked one-handed and also removed all jewelry.
Typically, the worker removes their wrist watch (this was a long time ago) and loops it through their belt (and of course removes any rings they were wearing).
Shoes are electrical safety shoes and have about an inch platform of good rubber, rated for this job.
Using a rated high-voltage probe, no problem measuring 1 kilovolt, using this protocol.
Every workstation had a resin handled probe (the 'shorting stick') with a ground braid (about 1" wide, like very large gauge solder wick).
That was used to discharge components that can hold a charge, when power has already been removed.
We never (ever) worked alone; there were always four other people close by, to notice anything unusual.

(Cathode Ray Tube .. a television picture tube is said to act like a hefty capacitor; the flyback transformer circuit is (was) probably near the kilovolt range, iirc).
The anode cap is that rubber thing connected by what looks like a spark plug wire, on the side of the tube.

I started using mostly Linux in 1994, and within a number of years (I still remember having a Windows 95 CDROM when they were new) I ended my frequent exposure to Windows (which began with Windows 3.00a iirc - shipped with a new PC I had a consulting firm build for me).
During this period I also switched to a Dvorak layout on all my keyboards, including my laptops. ;)
The combination of knowing little about current Windows troubleshooting, and a Dvorak layout on all my gear, had strong effects on being brought into conversations and activities surrounding Windows, in any way at all.
So, like, when interacting with relatives, and the kids would ask to use my laptop, I'd just smile and push it over to their side of the kitchen table.
And watch their faces when they looked at my laptop's keyboard.

funny thing is that I used 3 or 4 others "junk" PCs, that died of various causes... but this one stay (and have now inherited all the tasks of the others)
github says You can't comment at this time.
dusty citrus
Really. Okay that's good feedback, and something I would not have anticipated. Thanks.
aside: github said 'ProTip! Notify someone on an issue with a mention, like: @wa1tnr.'
@high galleon I don't see where it's inhibited. You'd have to be logged in, though.
high galleon
perhaps it was my side, I reloaded, it worked
dusty citrus
No you're in now.
I just saw you.
It worked -- I got the email notification I wanted! THANKS
high galleon
nice 🙂
dusty citrus
Yeah the trick with GitHub is to initiate the Issue yourself.
Then you're subscribed.
So you could have an 'issues tracker' issue open in every repository, for example.
high galleon
and you can't autosuscribe to your repo issues ?
dusty citrus
My problem was: I'd let older programs sit, unused by me (and not worked on) for several months, and they'd disappear off the top of the list of active software I was still working on.
Then, someone would go to an older repository and file an issue, which I was never notified about.
I tried stackexchange and other locations but could not find an answer, only comments that this was an ongoing feature request wrt github that nobody seems to think has been addressed.
high galleon
gota check that ... thanks for the heads up on this problem (I'm pretty new to github, i used git for years but localy)
dusty citrus
I think the work-around is going to be to open an issue yourself in every repository, with instrux as to why it's necessary.
(Issues aren't code they are conversations so this is harmless)
afaik, I am not subscribed to any Issue in any repository I own unless I interact with it first, which means I have to become aware of it.
high galleon
well ... I'd probably make a bot or something to mail me any news about my repos
dusty citrus
I would think a proper IFTTN type thing might do this job. ;)
If This, Then That
Beware the Turing tar-pit, where everything is possible, but not much is easy.
high galleon
yeah. and days have only 24 hours
dusty citrus
I need about 26.2 hours a day. ;) Perhaps variable-length. ;)
When we're all A.I. uploads I'll just twist the knob to the left or to the right, at bedtime. ;)
high galleon
so the way to do that is by webhooks. this one seems the one : https://developer.github.com/v3/activity/events/types/#issuecommentevent
dusty citrus
@high galleon I think I glanced at that in some context wrt this.
Sounds like they have it all wrong, however. This should not be a thing (at all). It should just happen.
They should have an opt-out feature if it's a nuisance relief issue.
The vast majority of users of github just plonk their complete program into the repository, with exactly zero revisions (just the initial commit).
dusty citrus
I'm not in the business of fixing their oversights. ;)
file an issue on that. ;) say it's broken. ;)
I would like to know what well-informed users are doing. If they're polling manually, that's unacceptable. ;)
drowsy zephyr
hey uh, is anyone here a graduate from electrical engineering?
or at least a professional engineer?
if so, is anyone available for dms, i have a predicament
late fulcrum
I did freelance circuit design for a few months? I don't know if that makes me a "professional engineer" or not, but I did get paid for it.
lapis bluff
Well, there's an organization that provides some kind of certification that allows you to call yourself a "professional engineer". But, since they don't have any authority to enforce a requirement, it has been ruled (by the FTC (I think), which does have authority) that anyone who has done anything that might be classed as engineering for recompense (not necessarily money) can call themselves that. There are a few places that require the specific requirement of that certification, but it tends to be in pre-digital domains (e.g. Civil Engineering, Hydrological Engineering). It has never really caught on in computer and digital electronics domains.
tame saddle
Also, in the US, each State may have its own requirements.
tame saddle
same. 😄
I should give an example though. a snippet from Florida's statute:
471.001 Purpose.—The Legislature deems it necessary in the interest of public health and safety to regulate
the practice of engineering in this state.
471.003 Qualifications for practice; exemptions.—
(1) No person other than a duly licensed engineer shall practice engineering or use the name or title of “licensed engineer,” “professional engineer,” or any other title, designation, words, letters, abbreviations, or device tending to indicate that such person holds an active license as an engineer in this state.
(2) The following persons are not required to be licensed under the provisions of this chapter as a licensed engineer:
the exemptions are long, but rather narrow.
dusty citrus
In Connecticut they had some kind of minor license/whatnot to fix PC's when they were first on the market (maybe four years into it).
I seem to remember people printing their license number in their yellow page ads. ;)
tame saddle
yellow pages. seems so long ago, but man they were just as useful as today's equivalent.
dusty citrus
The standard when I was in my 20's was I think an FCC License. I want to say 'first class radio license' but I don't remember. It was a big deal to have one of those, iirc.
So I think to get hired for some jobs you'd need a degree in EE from a university and that FCC license.
(I believe you could get that license without the EE though)
This could be it:
First Class Radiotelephone Operator License
https://www.fcc.gov/wireless/bureau-divisions/mobility-division/commercial-radio-operator-license-program/commercial-0
Discontinued, though. ;)
lapis bluff
@dusty citrus FCC licenses are for broadcasting, not engineering.
dusty citrus
I've held an FCC license for decades. ;)
Only someone with an EE could hope to pass the FCC First Class license, as I remember it.
lapis bluff
That's quite possible, although it's probably not a requirement, it's just that what the test is testing comes along with an EE degree, but sufficient experience might suffice.
dusty citrus
I just don't remember. The word seemed to be it was a little harder to get the First Class than Amateur Extra (which wasn't easy to pass).
Radio Maintenance and Repair .. on this page:

So a hack can work on police radio but not radio onboard a ship at sea. ;)
let's get out that golden screwdriver
lapis bluff
Yeah, I'm doing part of this from 50 year old memories of my father, who was the Chief Engineer for the Broadcast Division of a company. It owned a scad of TV and radio stations. At one point they were building a whole new broadcasting facility for one of the stations, and he was the only Engineer with the right Licenses to be the signoff that it met FCC rules, He brought a foot thick pile of schematics home one weekend and I had fun looking through them (although I didn't understand details).
dusty citrus
Everything on the market is type-accepted by the FCC, pretty much; maybe that reduces the need for expertise after manufacture.
I'm fairly certain broadcast TV and radio is still a site-specific engineering job. ;)
Apparently they're still a bit concerned about that Titanic v Iceberg problem. ;)
short bone
Just ask the question, "control systems" is too general
drowsy zephyr
well
this
assuming that NRP is an integer given from me, where do i go from there?
dusty citrus
That problem isn't stated in correct English.
If you cannot explain the question in simpler terms, it's fairly unlikely anyone here can even begin to address it.
(Asking a well-described question often leads to a path towards the solution)
drowsy zephyr
humm
okay uh
so the question at hand is that i need to design a proportional controller or to find a proportional integer from a PID controller and calculate the steady state error value from the system above
which is probably the equation below
there are some specifications that are given which is Tau*, K, and Tau
now how do i do this
short bone
What do you mean by design? Like make a schematic?
drowsy zephyr
i dont know
if im not mistaken, design mean looking for each parameters mathematically
it's been a while since i studied system controls, and yet i didnt even master it because it was so convoluted
so apparently, this equation is a first order step response
dusty citrus
I don't understand you well enough to have any response, but your English seems adequate. ;) @drowsy zephyr
Maybe use more common language instead of jargon.
Many of us are good with the basics.
drowsy zephyr
huh?
well alright i guess
the point is, i need to find a steady state error value from a first order system time response
dusty citrus
I have no idea what that means.
drowsy zephyr
same
dusty citrus
I'm just one person. ;) Good luck.
short bone
Assuming τ is the time constant of the controller, what is τ*?
drowsy zephyr
i have no idea
dusty citrus
;)
dusty citrus
I can’t get over how grammatically incorrect “Did I used to do that?” sounds

Typed this one the other day:
Don't you feel more like you do now, than you did when you came in?

I think that's meant to have a jazz club as background.

You can opt to have a portion of your pay "withheld" for tax purposes, then when you file your taxes, you'll owe any that wasn't already withheld, or get a refund if you withheld too much.
I suspect you won't owe any federal taxes, so you don't really need to withhold any, but I'm no tax expert.
