I have received FCC certification for an "intentional radiator", a 10W AM highway advisory radio. As I recall, if it has a clock that is 9kHz or greater, one needs to read the FCC regs very carefully. If it runs at DC, it should be fine. Don't assume that something that switches occasionally won't generate transients that will cause the FCC to catch you with a monitoring station.

The FCC doesn't have staff or budget to go after one-offs sold on Etsy.
Part 15 devices get certified because they're making 3700 of them in batches, at a production house that has done several other Part 15 production runs.
Enforcement has been focusing on very large LED signs along highways, where the manufacturer didn't bother with certification, and, far more importantly, made a product that creates harmful interference to two way mobile radio.
They've been target of budget cuts long enough to have gained a reputation for underenforcement.
OTOH they do leverage Dep't of Justice, to go after pirate radio operating on public broadcast bands.
Pirate radio is one of their things.
I'm just opining from the bleachers, of course. I don't know for certain.

Describe the taste of an onion
velvet pelican
@hasty quarry im not helping you find answers to your homework lol
hasty quarry
What kind of homework would ask that
I'm legitimately wondering how I could describe the taste of an onion
Sour doesn't really cut it, and neither does bitter
velvet pelican
Well that also depends on the onion
hasty quarry
A generic onion
hasty quarry
White
velvet pelican
Sour sweet hot
Cant really be labeled spicy since it doesnโt really stay hot after eating it its just a quick burn till ya swallow it
stoic mesa
we really need to be able to describe flavors and smells by RGB. values
hasty quarry
Bruh
velvet pelican
Lol we kinda can
Based off bitter sweet sour and spicy
This has bitter number 21 and sweet number 3
hasty quarry
Mmmmmm, this tastes very 0x0066ff
Oh, wow, this barbeque sauce is great...do I taste some 0xcc0000 in there?
late fulcrum
While there are only a few flavours sensed by the tongue, there are a huge number sensed nasally. Humans normally have around 7000 different odor receptors in their sinuses (and even more in their vomeronasal organs).
pearl vigil
What is the resolution of each receptor?
late fulcrum
The ultimate resolution is fairly fine, but the perceptible resolution varies enormously. My sense of smell is unusually acute (most perfumes and fragrances are overpowering), but I suspect the general population doesn't notice subtle scents.
velvet pelican
Yeah also if you have a broken septum you might not be able to smell at all and then everything becomes more bland in flavor
pearl vigil
Ah, so we need to resolve what the lowest usable smell resolution is, then we can represent the state of a sinus when experiencing a certain taste
If we make the scale with base 2 math in mind, we can mask bits like @hasty quarry's statement ๐
late fulcrum
It's probably logarithmic too, which complicates things somewhat, but gives a wide useful range (low end is likely on the order of parts per billion for some scents)
Ah yes, mercaptan is detectable at 1.6 parts per billion
hasty quarry
Ask what an onion tastes like, and watch a community helper join the conversation
And it turns into this
late fulcrum
I had seen that earlier and considered a flip reply like "sulfurous A, 13, sulfurous B, 27, tang 22, acrid 11, apocrine 3, pungency 0.47"
pearl vigil
We can fit the state of a sinus into 24500 bytes, not too shabby but our brains have amazing bandwidth
hasty quarry
What the heck
burnt tendon
Considering I came from an onion-friendly culture and married into an onion-loving culture, I tend to see onions as a base flavor.
hasty quarry
Even wirehead is here, it's over. Say goodbye to all sense of casualty in this conversation
burnt tendon
Define define
pearl vigil
Smell perception vs the state of a sinus are probably quite different
late fulcrum
This paper offers some amusing information like "acrylonitrile, odor threshold 21.4, odor description garlic-onion pungency, green" https://www.tandfonline.com/doi/pdf/10.1080/00022470.1969.10466465
hasty quarry
I'm laughing so hard right now
late fulcrum
Totally agree, the raw data and the perception can vary considerably, for a variety of reasons. For example, decenaldehyde in low concentrations, in combination with other scents, is part of several yummy food scents. However, in isolation, at higher concentration, it's the repulsive odor of stinkbugs.
If you're laughing so hard, we have done our jobs! ๐คช

@late fulcrum man i havent heard the word mercapitan in a while. Only reason i know what it is is due to doing utility locating. They say a drop of that stuff could give a person a bad enough headache to pass out
late fulcrum
I figured, it's used as an odorant for natural gas (which has no odor of its own), they chose it because it's effective in tiny quantities.
velvet pelican
Yeah i think they said a drop the size of a pin head can make enough smell for an entire distribution system for like a month pr something like that

And I'm more of a gear magpie / dice goblin than anything else.
I don't know what I'm doing and I don't know what's next.
swift hatch
If you want to do a little bit of DIY at the beginning to get a case and power going on the cheap, I can make some suggestions @dire viper
dire viper
@swift hatch that would be great! Though, at the moment, I don't have any modules, so it isn't pressing.
I have a Corsair TX650 handy, so it seemed like getting a +12V and a +5V off of that would be easy enough. I also have some old keyboard wall warts that are 12V.
swift hatch
Right on, @dire viper you'll need +12V and -12V as well as the +5V. This is my favorite diy kit: https://www.tindie.com/products/p0k3t0/basic-eurorack-power-supply-kit-or-assembled/
and this is a good busboard to go along with it, depending on the space you're going to fill. https://www.tindie.com/products/p0k3t0/basic-eurorack-busboard-kit/
I've go that setup in a cigar box for one of my Eurorack rigs.
dire viper
Nice! Ultimately I want to get a 48U server cage, and build into that, but that's a long way away.
swift hatch

that power supply uses 12VAC, so I run it off of this Jameco unit https://www.amazon.com/gp/product/B00B88621O
dire viper
@swift hatch OK, so, it looks like the total lay-out for power supply, busboard, and wall wart ends up being about $50? Plus tax, shipping, soldering time.
I'm starting to see how the Nifty Bundle really is cost effective.
$270 plus tax and shipping for two $100 modules, an 84 HP case, power supply, USB MIDI, MIDI in, MIDI thru, audio out.
And some patch cables.
dire viper
But then the goblin tendencies kick in and I just want to buy at least one of all the Korg Volca units, and at least one of everything made by Arturia.
Well, no, that's not entirely true.
I'd get two each of the Drumstep Pro and the Keystep Pro, rather than a pro and a non-pro.
I already have two Minilab Mk II due to mistaken ordering on my part.

hello
i have an interview with ford tomorrow for software dev in the infotainment system
and there were some points that seemed vague
was hoping someone could give me an opinion on what they think they mean so im not thinking im crazy
or mixing stuff up
full stack is just...
anything.....
no?
like programming wise
what does it mean to debug via stacks?
Does flashing raspian to an rpi count?
and idk what the last one means
crystal ore
"Debugging via stacks" might mean looking at stack traces for exceptions? Normally "full stack" refers to both frontend and backend web development, but that's a little weird for an embedded role.
median trench
I think ur right about debugging
And yeah im not sure
About full stack
What about flashing?
Would rpi count
crystal ore
"Flashing" normally means using SWD/JTAG/bootloaders to put firmware on microcontrollers, so not quite the same, but in the ballpark.
lapis bluff
"Full stack experience" may be a reference to having dealt with all seven layers in the OSI "stack". That would have been my immediate read on that, but I'm a Network Engineer (and even own the 9-layer T-shirt), so that's what it would mean in any job description in that field. But from other context here, I'm guessing it means something else.
late fulcrum
Usually, "full stack" in a modern job description refers to the frontend/backend situation EdKeyes mentioned, which indeed doesn't jibe with an "embedded" job.

You could, but it would be easier to just use a Pi 4, which already has two video outputs and a GPU.

@late fulcrum i mean for a final product. We want to save some money since rn we use a snapdragon for no apparent reason

late fulcrum
FPGAs can generate HDMI signals (there are some PMODs and demo code for it out there).
median trench
alrighty
well
hopefully i can find something
that seems suitable
@late fulcrum What benefits would using an FPGA provide over a standard CPU/GPU? I'm not sure where the FPGA lies in terms of cost, which i will do more research into. But I would imagine that the power consumption would be much lower and the processing times should be at least just as fast?
late fulcrum
It's kind of an apples and oranges situation, they're two different things (although you can implement a CPU as a "soft core" on an FPGA)
median trench
I understand that. But the power consumption can still be compared ?
late fulcrum
Yes. The data sheets for the various chips will detail the power supply voltage(s) and current(s).
median trench
alrighty

Many of them will have one supply for the core (often 1.2 or 1.8V), and another for the I/O.

getting pretty desperate, computer keeps shutting off randomly with even id 41 - kernel power error
idk if anyone can help, I tried like almost everything i saw online
it follows this weird cycle where it starts with the shutdown happening like once or twice a day
then it transitions to every few hours after a bit
and in the final stage it turns off right as u get into windows or before you even gets into windows
After windows forced a roll back of the updates it started working for a few days pretty well and updates started coming through and the problem started again but today I rolled back to that same update and now it is still shutting down every couple of hours
it dosent shutdown necessarily in the middle of stress tests like osst or heavy games but rather at just random times
really need this computer for school and if this happens in the middle of an exam or something I am so screwed
for context its a pretty high end custom built one with a power supply over the limit of the system

@cunning summit Maybe your psu is dead

late fulcrum
There are probably point of use switching regulators on the motherboard, with copious low-ESR filter capacitors. If those capacitors are wearing out, their ESR rises and they don't filter as effectively: when the filtering is insufficient, noise on the CPU power supply lines can cause problems like this.
cunning summit
Ok guys thanks I will try all of that
@late fulcrum so are you saying it could either be my motherboard or psu?
cunning summit
Also forgot to add, I can stay in bios almost indefinitely I think
I'm pretty sure the problem starts when I boot into windows or in the process of booting into it
velvet pelican
You could do what i did and download a temperature monitor to see if something is overheating. My main fan wassnt cooling enough from the chipset on mine and it acted the same way. It would happen more frequently once things were already hot which seems to be the case with what your experiencing

Hey all. This is off topic but probably relevant to people's interests.
Sphero has a flash sale on three of its littlebits kits.
Particularly of interest to @acoustic slate and @swift hatch and any other synth fans would be the https://sphero.com/collections/for-home/products/littlebits-electronic-music-inventor-kit
For $30, which is less than the costs of the individual components, even without the accessories.
The Mars Rover is also $30, also has more than the sale price in bits, and I'm trying to think how to use the light sensor, bar graph, long LED, and the Proximity sensor as ways to generate control signals to drive other little bits.
I'm sure it could all be done in other devices for less money, but it's also the fun of littlebits.

Sounds like they are still using something related to MS-DOS .BAT files.
The Command Prompt has been around forever, but with Windows 10, Microsoft is trying to make PowerShell the main command shell in the operating system.
This offers a very rich set of commands (called cmdlets) that are more integrated with Windows and most Microsoft products.
These cmdlets are functions that exist inside compiled DLLs on a system. Its primary purpose is to not only replace the Command Prompt but also batch files and VB scripts.
Command Prompt would help you understand legacy stuff; PowerShell (if it succeeds in replacing the Command Prompt) more about the future.

I think 50' is no longer a trailer, though I could be wrong.
I noticed the undercarriage of a parked trailer I used to walk by; it looked suspiciously like a bolted-on truck to carry what amounts to a cargo ship's container (the 'trailer').
Seemed pretty clear that container spent some of its days on the ocean, with no wheels ('truck').
But that, in the form I saw it in, it was something you haul with a tractor (front part of an 'eighteen-wheeler' cargo vehicle).

I remember when you started the project and were asking about motors, slides, and limit switches. At that point I didn't realize you were building a house, I just imagined it was some tabletop apparatus. Fortunately, the advice I gave then was general in nature, and applies to both large and small constructions. I've been enjoying watching the progress, it's a really neat project.

Can we talk about just how twisted the results from the Pfizer vaccine trial are? It's a tiny little snippet of mRNA that encodes part of a protein, wrapped in a lipid capsule, delivered with some random other chemicals to kick your immune system in just the right way... and it looks like it might be working?

guys i need help
so apparently i have an assignment where i need to control a position of a motor using PID
here's the problem, the motor has an incremental encoder in it
i was thinking of starting at 0 and then incrementing by 1 for each A pulse so using relative degrees from the starting position
that's how i read the current position
So, the speed of the motor is controlled with voltage while the setpoint is the angle of the motor that we want
im having trouble determining which one is the input, the setpoint, and the output
currently i have the input set as the angle the motor is currently in, the setpoint as user input, and the output as voltage, is that correct?

I've gotten really spoiled with CircuitPython. Hadn't done any Python until starting CircuitPython last year (have since done a few CPython things). But trying to get Python working on a (shared) web server to receive client data data and respond to web requests, flying blind with no REPL, isn't nearly as fun and satisfying as the quick cycles and immediate feedback with CircuitPython (or even desktop Python). Basic server Python should be much easier, HTTP has been around for decades.

If you add a space to the beginning of your bash shell command line, it isn't available (even immediately, in-context) in the shell history.
It's as if you'd never typed it. I assume (haven't tested) that this also would be the case for the record (stored in .bash_history).
The command executes (I'll assume it does so normally). Just isn't recorded.
SO if your history file is full of repeated utterances you don't value, and don't need to know the sequence in which they were given - this seems to be a means to keep them from cluttering the history file.

It can get even more confusing in networks, generally you call two communicating programs client and server, and sometimes people think when you say "client" you mean the person, not the program. This can get even more twisted, for example in the X Window System, the server is the part closest to the user (managing the actual display) and the client is the (possibly) remote program; also in DNS which did not refer to clients and servers in the initial spec because many of the pieces can switch between modes, or even do both at once.

Ceramic caps will probably have less ESR as high frequencies. Depending on the speed of the logic, it may not matter.

1 MHz clock or 1 MHz max speed on the logic? That's like 4000 series CMOS at 5V.

Do you really mean 1mHz as in 1 millihertz or 1MHz as in 1 megahertz? There is a difference.

megahertz
stone orbit
I'm assuming that you are referring to 1MHz clock speed. Very few people use logic today that has a maximum speed of 1MHz unless it is intended for very low power. Most logic today will run at much higher frequencies.
Perhaps you should try your mylar caps and see if there are switching transients on Vcc or Gnd with an o'scope.

x86 is a relic from 50 years ago when a CISC CPU was needed due to slower memory. It is fast becasue of the number of years of development and money it has vs arm, but fun fact, modern x86 CPUs are composed of many RISC CPUs. And with fast memory, RISC in some work loads can 100% outperform x86, and with less energy used. Check out the ARM servers they are amazing

It is about usability, not really a memory. It is easier to copy a short link, so people more likely will go to the source etc. I resolved it by adding a link just to a repo.

@burnt tendon I feel the same. I mean, in a different world a worthy successor to Arecibo would be in the works if not complete, but in the world we have it's like we just don't care about anymore about finding a better understanding of this universe and it really pains me deep inside.
Besides seeing to everyone's basic needs, which we're also bad at, "understanding things" is one of the most important things I feel we can do as thinking beings.

I guess a higher-level version of that thinking is that interferometry works pretty darn well... until it doesn't.

Likely they don't have nearly the funding needed to rebuild Arecibo, so they are just giving up on it, and leaving china with the only facility comparable.

(not sure what channel to use) In old radios they use a belt/string, Dial String Mechanisms [0] , to move an indicator to show the current station. Can a hobbyist create one of these mechanisms? Are there parts out there to accomplish this or will everything have to made by me?
[0] https://childhoodradio.com/dial-string-mechanisms/
late fulcrum
Seems doable. The mechanisms themselves aren't that complicated and many of the pointers are simple sheet metal assemblies attached to the cord (often glued: nail polish would do fine)
fathom relic
easiest would probably be to take apart an old broken down radio, both to see how it's done, and for parts. The ones I've seen have a non stretchy, durable string, looped around multiple pulleys, loop completed with a tension spring. The pointer is sheet metal, cut into a forked shape and bent so the string threads through it, and possibly secured with a dot of varnish or glue. One of the pulleys is attached to the tuning knob, and others may be attached directly or indirectly to variable air capacitors that do the actual tuning. Even somewhat newer radios with analog tuning (80s+) and some car radios used similar mechanisms, even if the indicator is a red LED
weary fiber
dusty citrus
The main function of the dial string system is anti-backlash: what happens when you overshoot and change the direction (clockwise or ccw) in which you were tuning?
Next important is flywheel .. how rapidly can you slew from one end of the band, to the other?
The largest pulley is split, iirc. I haven't dismantled any of them, since they were operational when I acquired them.
Slide rule scale is usual.
My Hammarlund HQ-140-X shortwave has two disks with circular scales (like a circular slide rule).
The escutcheon differential, the difference in depth of the parallel planes, is a lot.
Those disks are set way deeper into the radio than the front facing panel.

There needs to be a shortcut
I think my brother tried doing them in a crockpot, not sure how that came out

caramelizing onion is surprisingly difficult, most of the time I end up burning them because I loose patience after 40 minutes and turn up the heat.

What's the general thoughts on a tool like Hakko's FR-301 desoldering vacuum pump over a traditional, manual solder pump?
I've never had the best luck with the manual pumps, and all the times I've seen folks use the electric tool, it seems....I dunno, easy.
late fulcrum
I'd love to give it a try
grave crest
@late fulcrum I was watching a streamer repair a NES, and to remove the solder joints was as simple as -add new solder- then use tool to bzzt bzzt bzzt each of the through-hole connections.
And I stopped and looked at my manual solder pump on my desk, and said out loud -- you've never given me anything but an exercise in patience.
late fulcrum
That does sound really nice
high galleon
@grave crest I saw a guy using desoldering braid one day, seemed a lot easier than the manual pump... but I never tested myself.
stone orbit
@grave crest At least one local contract manufacturer is exclusively Hakko. I mostly have Edsyn but when those quit, Ill change to Hakko,
I have a manual solder sucker, braid and a de-soldering vacuum pump. I simply don't bother with the manual unit at all.
The braid is great for fine pitch ICs. Simply blob solder all over the pins and then use braid to remove almost all of it. The joints are left with just the right (small) amount of solder with perfect fillets.
Most people tend to think solder is like chocolate frosting on cake, the more the better. For SMT, a very small amount of solder with nice fillets is prefered.

more progress on the PCB!
due to the issue with eagle crashing when I import files from schematics, i need to do the entire PCB the hard way, which is manually connecting the signals
it's not the end of the world though! manually connecting the nets and signals means i have more control of what gate is used where
it's a little stressful though cause i have a lot of places where I could of screwed up
late fulcrum
Looking nice! You could compare nodelists, but that would likely require writing custom software. Which version of Eagle is crashing on you?

I see different advice given about whether to use the same SSID for 2.4GHz and 5GHz in a home setting. For 2.4GHz-only devices it doesn't matter. Typically 5GHz devices also have 2.4GHz and should be able to intelligently roam across them. Personally, I like the simplicity of a shared SSID for both bands, unless you really know what you're doing and have a distinct need to tune the network. Other factors I'm missing?
