general-chat

[blissful roost]

That's fair enough... I don't suppose it could be any worse than the stock controller in the keyboard. Lol

[thick wind]

If we’re talking the ibm keyboards I’m thinking of, the controller is probably decades old and supplemented with extra ICs in the form of decoders or shift registers. Since rollover today is pretty much strictly tied to the controller’s endpoint capability, you could make use of the inbuilt ics if you can somehow tie in your pico to those, rather than directly to the keys.

[blissful roost]

Yeah. I'll have to take a look later. 🙂

Ohh.. and too dang heavy!

[thick wind]

They have their own particular advantages over more modern displays, to be fair. For a productivity application though, kinda hard to justify…

[blissful roost]

Yeah, for sure... Retro, ok.. I'll let it pass.

[burnt vale]

is that how humidifying atomizers work? I could swear I remember a long time ago reading about ones that used RF to electrically force the water into vibrating apart. But I was a teenager then

oops, lol, didnt notice that was old conversation

[thick wind]

There are a number of different mechanisms that can atomize a fluid. I focused on the ultrasonic variety due to the context of conversation, but there are electrostatic atomizers as well. I don’t know about the RF aspect, but I think some applications use a high voltage to achieve a similar effect.

[burnt vale]

I wonder if you can make a steam cannon with an RF atomizer and some HF power mosfets. ... well I know what I am looking up now

maybe need to add some sort of heating thingamabob to work on the mist if the atomizer doesnt heat it up enough

O_O http://wwwd.graco.com/training/concept_and_theory/Atomization v2.pdf

When you drop these things, you don't worry about whether you broke the CRT or not, you worry about whether you broke the table, or the floor, or not.

[burnt vale]

dont wipe the static off your CRT when you're holding an n64 controller unless you wanna zap the Z-button and never be able to properly play shadows of the empire or starfox 64 ever again

who else damaged something as a kid wiping static off the screen?

[rapid geode]

noone else was silly enough to do that. dont they learn you nothin in that school of yours?

😛

[thick wind]

Can’t say I’ve ever damaged anything, but I remember as a kid I liked to spam the degausser on my old monitor for fun

Didn’t know what it was doing, but the big thunk and image distortion was funny to me for whatever reason.

[burnt vale]

the first time I did that, I almost had a panic attack because I thought the word sounded neat and wasnt expecting something so out of the ordinary

[burnt vale]

anyone have a fun project (with associated code) to use an atmel chip/arduino with a z80? Maybe with an OLED? I have an old one from an air conditioner system controller I got out of a junkyard

[late fulcrum]

You could do something like Ben Eater's breadboard build. He used an Arduino as a bus analyzer for a 6502, I hacked up his code and did a similar thing with an 1802. You could likely swap in a Z80.

Alternatively, you could have the Z80 doing one thing and the Arduino another, and use a couple of pins for them to synchronize/communicate.

[hasty quarry]

Hey so I wanna try something, and I wanna know if someone could enlighten me on whether it’d work the way I expect or not

I like to screen record some things on my laptop using OBS, but to be honest my laptop is awful at that multitasking, and my frames really pay up

I found one of these, where you plug the USB part into your computer, and tell OBS to get a video input from the USB, which gets converted from an HDMI you plug into it

Would it actually be faster to record by using this thing, with the HDMI input plugged into the laptop’s own HDMI output?

Or would that just be a more roundabout way to do the same thing, and not any faster

[late fulcrum]

Usually a hardware loopthrough is going to be more annoying than just running screen capture software directly.

[whole jacinth]

i recall that on cheaper hardware, some of the compression might run on your computer instead of the capture device, so you don't necessarily gain much

[thick wind]

A lot of professional streaming setups use a second computer for screen capture and streaming. While you don’t need to go that far for your purpose, you could consider a similar approach if you have an extra laptop or single board computer at your disposal.

[shadow siren]

Yes just set up a scene in obs that contains the window or whole screen you want to record and bypass that capture device

assuming you want to screen record on the same laptop that is running obs

[hasty quarry]

Precisely what I’m doing, and what I want to not do

Because it annihilates my frames

[hasty quarry]

I actually thought about this, I have another laptop that I could get to do the render work. That sounds good

[shadow siren]

are you trying to capture a game

[hasty quarry]

Yes

[shadow siren]

I thought you wanted to record a desktop but yes a second machine is better.

I use this to capture stuff from other computers output

[hasty quarry]

For desktops

Aren’t there PCIe modules precisely for this?

[shadow siren]

no it's for anything, it goes between your computer and a monitor and the capture port can be sent to a second computer, it was specifically designed to capture game play. Yes there are PCIe capture cards also but they tend to get expensive.

One issue you can run into is if the game uses the HDCP to the monitor and sending the game directly to a capture card can result in a black screen due to DRM

[hasty quarry]

No it was a question

There are PCIe modules that are for this, right?

[shadow siren]

Yes several makers of them, Black magic, Elgato etc..

PCIe cards, don't expect to find one that can be put into a laptop only a PC

[late fulcrum]

You could put a PCI video digitizer into an eGPU connected to a laptop, but that way lies madness.

[shadow siren]

umm yeah thunderbolt based external PCIe slot cabinet then put the card into it.

I have this card

[late fulcrum]

A lot of vendors don't support modern operating systems 😦

[shadow siren]

Where I work we use a lot of black magic hardware the problem is older stuff gets pushed to the side for driver support in favor of newer stuff

[tardy badger]

Daisychaining usually causes fires, so maybe 🤔

Lol

[hasty quarry]

How does it

[whole jacinth]

more of an issue with chaining power strips or extension cords for mains power. every connection is a point that can develop enough resistance to heat up and start fires

[static flare]

I need to get mine set up, but I'm still not entirely sure what I need for it

[silver shale]

Basically got everything but the tape that was listed in the guide. Got the TO1755SB specifically.

[late fulcrum]

Care to share any pics of the resulting board?

[silver shale]

first test was just to see if it heated up correctly, no board yet

plan on using it with memory modules with mainly BGA chips

[late fulcrum]

That makes sense, BGA tends to work best with controlled heating.

[silver shale]

may or may not be SAC302

[static flare]

I'm probably going to end up going a different route with my toaster oven, tbh, I'm probably gonna need to do some HV stuff

[late fulcrum]

I had been eyeing the Whizoo oven controllers myself. I do enjoy HV stuff as well.

[silver shale]

I am considering rewriting the code for the EZ Make Oven, maybe in C

[static flare]

oh HV terrifies me

Last time I tried making something with it, it exploded

[late fulcrum]

Testing my dodgy idea of using the PWM from a switching regulator to directly drive a flyback to obtain HV. Not only did it actually work (the lit neon bulb in the anode cup illustrates this), but I later found I didn't even have to wind my own primary on the core, one of the built-in windings turned out to be suitable.

[silver shale]

heh, nice

testing the SAC305 profile I made.

[late fulcrum]

Ah, decent silver content in that.

I normally stick with 62/36/2 myself.

[silver shale]

micron mentioned that they used SAC302 on DDR4 chips, did not find much info on 302 profiles so went with the 305 info.

[static flare]

what solder paste do y'all recommend for beginners (predominately hot air starting out)

[lusty fossil]

Leaded

[brave copper]

how to fork an Emulator and turn it into a bare metal Emulator for Pi?

[late fulcrum]

I agree with leaded.While I like silver bearing solder, it's hard to find in T5 paste form. T5 particle size is nice if you're dispensing with a syringe, as it flows better (you can thin it with flux too). Flux type is kind of a personal taste thing. I'm fond of RMA flux, but some people like water soluble or other flux properties.

[tardy badger]

The low temp bismuth solder has silver in it

It comes in T5

https://www.digikey.com/en/products/detail/SMDLTLFP10T5/3972566

Granted, it’s only 0.4% silver

[rapid geode]

[late fulcrum]

I haven't tried the bismuth solders

[tardy badger]

I have had really good experience with it, definitely recommend.

[burnt tendon]

Well, that's one way to get a lot of other people into your bismuth, then.

[silver shale]

Would an LM317 constant current source circuit work for charging SLA batteries for a UPS system?

Currently making one with a 2-ohm resistor, which would give around 630mA of current(?)

[late fulcrum]

If you limit the voltage as well, it would be a reasonable float/trickle charger, I suppose. Ideally the voltage would be adjusted for the temperature of the batteries.

[silver shale]

the setup is very sketchy, I am going to have to keep it supervised the whole time its charging

small price to pay compared to the other option

should not take too long at 630mA, each battery is charged separately since charging the entire pack would require at least 48 volts at 800mA, which I do not have a power supply with such specifications at the moment

[silver shale]

Batteries were all dry, explaining why they could not charge

[tardy badger]

You could try getting a trickle charger. I’ve heard they are helpful for charging dry batteries

[silver shale]

completely dry, need to find battery solution for reconditioning.

Hello, can anyone shed light to the reason why Adafruit is requiring a sign in just to view a product? I have no intention of buying it at the moment, simply wanting to access its documentation

https://www.adafruit.com/product/4064

This is the product

I find this to be kind of distasteful tbh, people should be able to access documentation for free, without giving over money or data

what is the error you're seeing? do you have the same problem in a fresh private browser window?

[rapid geode]

yeah i dont get anything asking to sign in

[tardy bough]

Interesting it does not occur in private windows. The error is that the link to the product would always redirect me to the sign in page.

[rapid geode]

odd

clear cache/cookies maybe?

[whole jacinth]

i suspect there's some misconfiguration of the web servers. i've seen it from time to time. maybe try emailing [e-mail] with as many details as you can?

I have a program on a raspberry pi that's meant to run at my school

Headless, and using a barcode scanner's inputs to store some things in a database every time a barcode is scanned by it

I have it hooked to ethernet, but I checked logs and it turns out my school's network is very rude, and just doesn't like the raspberry pi accessing anything online

I have no idea what alternatives I have here

[umbral phoenix]

check with the school's tech people, it could be filtering the whole device, or just certain ports or protocols, you might be able to get an exception

various ways to work around (with permission), depending on what the limitation is... ssh tunnel, vpn, tor, cellular module or phone hotspot,...

[hasty quarry]

Trying that at the moment

Thing is, I'm in a bit of a rush, I expected this would work quickly

And there's something I don't understand here, too

My database is https://remotemysql.com. The ethernet cable I hooked to was previously hooked to an all-in-one in the computer lab which could access that website totally fine

But when I gave the pi that same ethernet connection, it couldn't access anything. How is this

What's up with the hardware-specificness, I didn't know that was possible

Or well, maybe they're literally just allowing specific local IP addresses internet access, for security

[thick wind]

Do you have hotspot capability? That’s usually the quick fix for demos…

[hasty quarry]

Not quite

I would've certainly tried it by now, but I don't have one

I'm hoping the tech people will actually speak to me, but since this is a school, the whole "higher ups" dynamic makes little tiny decisions take so unbearably long

Awful

[tardy badger]

It’s probably MAC address based

It’s a pretty common tactic for school networks these days

[hasty quarry]

Ah okay

That's what I thought it may be

But I couldn't be too sure

[whole jacinth]

yeah, school networks often put unregistered devices into a "jail" or otherwise restricted subnet

[hasty quarry]

Does every network request have a MAC in some kind of header?

How does this work

Is it as simple as "hmm I don't know you, blocked"

[tardy badger]

Yeah, usually The local router assigns an IP address based off a valid MAC address and sets up routes accordingly

I kind of oversimplified that

[hasty quarry]

That is definitely what it looks like, actually

Like it's just isolated, I can't ping anything in there

[whole jacinth]

if you're lucky, the jail network tries to redirect web traffic to show a local web page that explains how to register devices, or whom to contact to do so

[silver shale]

Well... I just had a power supply and a LM317 go at the same time

This is why regulator circuits have diodes

How does one balance Lead-acid batteries?

I think I got the voltage to where the UPS would take over

I haven't seen that style of labeling. Normally 10k would be 103, for example.

[ebon dew]

Getting some outer bands. Nice breeze. Temperature actually dropped a good 5-10 degrees. Unexpected. It's usually a sweltering sauna after a hurricane as the sky gets super clear and all the warm air it brings from the south just bakes you. No power and sauna, that's FL though.

[late fulcrum]

Yes, the EIA-96 code for 1% resistors specifies 01B = 1kΩ and 01C as 10kΩ.

Sebring got whacked hard couple years ago. Can’t remember which one. West coast been taking the lions share of them this decade.

I got hit directly 3 times in one year in Like 2006 by Francis Jean and Ivan. Just when we got power back got hit again.

[burnt vale]

I was stuck in a horrible house in new orleans for the one that hit two years ago and I had a front row view to my whole neighborhood being rendered uninhabitable. It was terrifying knowing the house was termite eaten

the one I am in now has way more integrity

[tardy badger]

2004

I remember that year

We evacuated for Francis because it was supposed to be bad, it wasn’t so they didn’t make it mandatory to evacuate for Jean which was interesting to go through. Ivan hit much more south than those two but only after it was on its second way around

[ebon dew]

Francis was at night and jean during the day. Only reason Jean didn’t do more damage is because Francis took out all the weak stuff first.

I remember watching Jean break part of my avacodo tree off and hurl a massive branch 10 ft. It was impressive. I’ll always remember it was during the day because of that.

[dusty citrus]

stupid question, what does digikey mean for bulk? I mean how many unit or kg there are in one "bulk"? or do they literally mean one single unit?

having kids is having a biohazard level 4 facility running around with its airlocks double-breached and the windows open - note the 'is', not a simile like 'is like'.

[rapid geode]

rhodents?

[hollow kelp]

This would be even funnier if you were followers of certain nordic traditional religions.

though if you are hail and well met (though as a fenrirsmun I respect if the well met is not reciprocated)

[hollow kelp]

It means the unit of purchase in multiples. So that QTY 1, that's one unit of the thing -- not really technically bulk, buut 1 is a multiple. And the greater the bulk (multiplier) the less you pay each. So if you buy 1, you pay 2,43000euro. If you buy 10, you pay 16,19000 euro, buy 100, 124,580 euro, etc. Generally it is assumed such tables show aa range. So 1-9 will pay the unit price (2,43000euro each). 10-99 will pay the 10-unit price (1,61900 euro each). 100-499 will pay the 100 unit price (1,24580 euro each), etc.

basically, "buy more units, pay less per unit"

Businesses tend to offer bulk pricing because the more product they can move, the less inventory they have to keep and the less risk they have for filling their storage, which can cause them to have to close production lines (which can sometimes cost a lot to restart, and can cause employee unhappiness if the employees have to be sent home and not earn wage). People buying large numbers of units 1.) help their pipeline flow, and 2.) tend to be repeat buyers, so lowering the cost-per-unit is a way of passing the savings on while enjoying the guaranteed per-part margin.

[dusty citrus]

but if QTY is under the Bulk text, should I consider it to be some sort of a bag with x number of unit, or a single unit?

[hollow kelp]

Bulk is their "how many are you buying" table. Unless the unit is "a box of 10", a unit is a single piece.

If you're looking to buy a TCA9548A, and the listing is for individual TCA9548A, then a unit is one individual TCA9548A. If the listing is for "a box of ten" then a unit is 1 box.

Would you be williing to share a link to where you're seeing that table? Context in this case is important because of the example just given.

[dusty citrus]

Okay, so for this, the detailed description tells us that what we are considering is a UV emitter. Singular. So we're not looking at a kit or something. The Package is "Bulk." The ? icon when you hover over it explains what bulk is inthis context -- they're not packaged. If you buy 100 of these, you're going to get 100 loose UV LEDs tossed in a bag all jumbled up.

Since we're looking at a singular item (one LED), the bulk on the RIGHT means "how many you buying, buy more units (single LEDs) and pay less per unit (single LEDs)."

Comparing to another listing where one buys a box of 100, its seems they may be doing something a little different than I'm used to with their bulk pricing. Possibly someone in AdaFruit's procurement department could give you more specifics on Digi-Key's information specifically. It is arranged a little odd compared to the generic expectations one uses reading most business sites.

Whenever you have some confusion though -- never hurts to grab a phone and give a quick call or send an email. You'll find the Italy support contact info at the bottom of that page. Don't ever feel like you're inconveniencing the person on the other end of the line -- it's their job to help you or find someone who can, and as long as you sincerely are interested in the product (even if you later, after gathering that info, choose not to buy), you are a legit customer.

Okay. Using another listing I figured out the difference.

So the first line is the minimum multiplier. So for your LED, the minimum QTY is 1. You can buy as many as you want, no restrictions.

The page I'm looking at, https://www.digikey.it/en/products/detail/american-bright-optoelectronics-corporation/AB-10TA05-18K/9959327, has a QTY of 100. Thee package is Box. So I'm figuring this is a box of 100. Each piece is 5 Euro5,84360, the Ext Price then is the package price. If you try to order just 1, you get an error that the quantity entered must be a multiple of 100. So it seems certain that you're buying a box of 100, and they're not going to split a box for you... so you have to order units but understand they're packaged in boxes of 100.

And going back to your page, I find I can type in a keysmash of any number up to their In Stock and it'll accept it. Using 7654, which is between 5000 and 10000, I see it grabs the unit price from the 5000 line. So yes, this seems to explain the difference from what I'm usually used to.

(don't be afraid to play with text entry boxes on web sites -- unless you've put in payment info or logged in, you're committing to nothing :) )

Does this help you at least feel better able to work with the information given? Even if not fully understanding or not fully confident?

[opaque panther]

Early this morning it was pouring in Boynton Beach where I live.

[dusty citrus]

yeah in the end I contacted them anyway, but I was looking for answers so maybe I could get items faster, thank though

no way that I'm paying 1.5€ for a single led though
if it's like that, do you have any suggestions from where buying low volume stuff within Europe cheaply and fastly?
I mean I could get stuff from AliExpress, but waiting like a month... no

[hollow kelp]

I don't, sorry. Right now I'm mostly focused on preassembled discrete units like Qwiic/STEMMA QT sensors.

and am in the uSA so even less familiar with the EU market.

[thick wind]

Cheap is relative, and not knowing what you’re targeting, this is a bit tough for me. I hear mouser has pretty good distribution in Europe though?

[late fulcrum]

Hurricanes are fun!

[hollow kelp]

Because hurricanes preferentially impact beaches which are highly desirable when there aren't hurricanes, and hurricanes don't hit every beach every year. If people could process durations over a couple of days or weeks, could accurately process statistics without substantial and complex education (and ... even then...), we wouldn't have climate problem for example.

Humans are completely fudged for the world in which we live, we are fundamentally the engines of our own annihilation.

[rapid geode]

i have a beach here, and no hurricanes

or earthquakes

or floods

[tardy badger]

Hurricanes exist for one thing, Hurricane parties

[hollow kelp]

Remember what I said about statistical awareness? That response is a perfect example.

[tardy badger]

My parents had a hurricane party in 2004 for hurricane Jeanne

It was fun

[rapid geode]

....

i had a snow day. is that the same?

[tardy badger]

We stayed at a friends house and I got to hear hurricane force winds wreck a fence like it was made of toothpicks

Seeing worms and frogs crawling up the stucco siding of houses was neat too

[rapid geode]

ha

[tardy badger]

It’s wild to think that was 18 years ago

[thick wind]

Kinda sorta? Just like how Atlantic Canada and northeastern us are conditioned for blizzards, Florida knows a thing or two about hurricanes.

[tardy badger]

Which is why they have Hurricane parties lol

[rapid geode]

atlantic canada knows to move to toronto to get away from blizzards

😛

[thick wind]

Heck, I hear people in southern California skip school and work on rainy days because they’re scared to drive in it…

[rapid geode]

well in LA specifically, when it does rain those 6 days a year, they can be flash floods

[tardy badger]

I dislike driving in rain mostly because other people lose all ability to drive when it rains

[thick wind]

Anyone remember that ice storm that took out power in Texas?

[thick wind]

Exactly, because their infrastructure isn’t designed to handle it

Rainy places have proper drainage, LA not so much.

[tardy badger]

It’s also why I dislike driving in snow, most people lose all ability to drive in it. Common sense right out the window

[rapid geode]

its a bit more complex than just that. it is designed to handle it, quite well. but it is extreme weather. just.. dont live there. 🙂

[tardy badger]

I love driving in the snow when it’s just me and no other cars

[rapid geode]

we do not get anything very extreme here. bit of cold, bit of heat, bit of rain, snow, wind. but nothing that would cause problems normally

[tardy badger]

For now anyway

Plenty of places that were pretty mild weather and potential natural disaster wise are seeing that change

[thick wind]

My theory is every place has their own pros and cons. Some a little less, some a little more.

[tardy badger]

And that is only going to shift with climate change

[thick wind]

I don’t mind the weather here, but not a fan of the bugs.

Most notably, ticks…

[tardy badger]

I’m not a fan of bugs either

[rapid geode]

yes. im just saying that in places like florida, the cons vastly outweigh the pros.

[tardy badger]

For some reason hornets and wasps really like me

[rapid geode]

i hate bugs. this year a late frost killed the mosquitoes which was nice.

[tardy badger]

I love gardening, hate the bug aspect of it

Mosquitoes weren’t bad here too

[rapid geode]

id like to have something that sends all the rats to bufalo

they are the only really bad pest here

squirrels steal my veggies, but they dont do much else

[tardy badger]

Netting helps a little bit

Until the squirrels realize they can eat through it

[thick wind]

A squirrel once stole my wife’s hot dog.

She never forgave them for that.

[rapid geode]

ha

i saw a squirel steal one of my hot peppers, take a bite, then decide... nope

[thick wind]

Yes, out from the bun in her hands.

[tardy badger]

I’m not a fan is squirrels on the account that they will charge at you for no apparent reason

[thick wind]

Wildlife in tourist areas are wild, man.

[tardy badger]

Indeed

[rapid geode]

a squirrel stole the brioche bun off my sandwich once when i walked away for 5 seconds

[tardy badger]

I worked in West Yellowstone Montana one summer

My favorite tourist question was when they let the buffalo and other animals out

Lol

[rapid geode]

i see very little wildlife here

chipmunks

and ive seen lots of little snakes lately

(in the forest)

[thick wind]

We have deer. I’d like to see them less.

[tardy badger]

We have lots of nope ropes here

Lots of seagulls

[thick wind]

Don’t really mind the rabbits and turkeys, but deer are the worst.

[tardy badger]

Which is kind of funny tbh

[rapid geode]

in my yard its just squirrels, rats, racoons, skunks, fat robins, doves, crows, and the odd rabbit

oooh, i did see a wild turkey on the trail

[tardy badger]

I’ve almost hit wild turkeys when I lived in North Carolina

[thick wind]

Where the deer goes, the rticks follow.

[rapid geode]

no deer here

or bears

[thick wind]

Oh yeah and they have no respect for cars.

[tardy badger]

Chiggers are the worst part of the south eastern US

[rapid geode]

or moose

[thick wind]

…chi what

[tardy badger]

Those little red bugs

That way up your legs

[rapid geode]

i dont think we have those here

[thick wind]

Never heard of ‘em, but they remind me of ticks.

[tardy badger]

Berry bugs, harvest mites

[rapid geode]

lots of spiders here

[tardy badger]

https://en.m.wikipedia.org/wiki/Trombiculidae

[rapid geode]

yuk

[tardy badger]

Yeah

I’ve not personally encountered them but I know people who have and they ended up with a pretty bad rash

[rapid geode]

i havent seen any black widows or rattlesnakes. they are the only really dangerous animals that live here.

[tardy badger]

According to Wikipedia, chiggers can be found most anywhere in the world

[rapid geode]

maybe the rats ate them

[tardy badger]

Probably possums

Possums eat lots of bad little bugs

[rapid geode]

we dont have those

[shadow siren]

Nothing like a 27 floor clearing fire alarm

[tardy badger]

https://www.thecanadianencyclopedia.ca/en/article/opossum

Looks like Canada has opossums 🙂

[rapid geode]

canada is pretty big

no, we dont have those here

[tardy badger]

There’s so many people in this discord I forget where people are located

[rapid geode]

saying canada has someing is like saying spain has something so ukraine does too

😛

[tardy badger]

I’m saying I am probably misremembering if you’re in Canada or the UK

Or somewhere else 😛

[rapid geode]

im in canada. we dont have opossums here

[tardy badger]

Where you are specifically? Because lots of official resources do say otherwise for Canada in general

[rapid geode]

im where there are no opossum

s

[tardy badger]

Gotcha, just wanted to clarify

[rapid geode]

maybe the zoo has some

[tardy badger]

Maybe in a few more decades as things get warmer they’ll migrate further north

[rapid geode]

it doesnt get warmer here. climate change is just a scam to make us turn the heating down

😛

[vivid turret]

Hi. Does anybody know what this might be?

It was inside a billy bass talking fish decoration. (I've seen other teardown videos but they don't mention this)

[tardy badger]

I’m willing to say it might be some kind of speaker

[vivid turret]

I thought it might be too, but there's another speaker.
Also, when I play the music, this thing doesn't seem to emit any sound.

[tardy badger]

Hmm, maybe a vibration sensor

Does it claim to be movement activated?

[vivid turret]

yeah, it's movement activated

that must be it. There's another sensor infront near the button, but maybe that's just so it doesn't turn on at night.

hello guys

i need some help with my fingerprint sensor

how i can store more than 127 fingerprints?

[late fulcrum]

That's more than fit in its memory? I wonder if you can read them out and store them elsewhere and put them back in when you need them.

[ebon dew]

lost power a couple times now, winds up to 45 here. don't expect to have power for much longer

[static flare]

used to get blackouts all the time in Sydney, luckily not so much since i moved to Melbourne

[bitter iris]

are there any good resources for learning how to read SPI lookup tables? I'm reading this datasheet and am having a hard time understanding how to use some of the commands based on the description. https://www.waveshare.com/w/upload/7/79/2.9inch-e-paper-v2-specification.pdf

[crystal ore]

Not really, I'm afraid, since every datasheet is different, and many of them do unfortunately require a little bit of staring at to figure out. If you're stuck on anything in particular, folks here can probably help, since often all it takes is an extra set of eyes.

[dusty citrus]

how are aliexpress items so cheap? for an hobbist pricing on digikey, mouser, farnell and similar stores are just proibitive, a single led on mouser does cost 1.30 euro, on aliexpress the same led does cost 3 cents; googling I do see that they might be fakes, defects, third hand parts and whatever, but so fare I had not issues besides slow shipping

[dapper wraith]

I usually find that Digi-Key has a very wide price range. From super high spect and expensive components to cheaper ones, but not as cheap as AliExpress. Was the €1.30 led the only option they had?

[thick wind]

There are a lot of factors at play that essentially boil down to all the same reasons why so many things are made in china in the first place. Low labor costs, high volumes, very little protection for intellectual property…

[dusty citrus]

the cheapest yes

[tardy badger]

Every 4 weeks I celebrate “rents paid and that’s about it” day

[rapid geode]

i celebrate "i bought a cheap house" day. cause otherwise i would just cry

haha

speaking of cheap house, its almost time to start hooking up my smart home junk. light switches and thermostat

[dusty citrus]

I need to find a way to not feel nauseated after staying a while on the screen

[rapid geode]

um

[dusty citrus]

you might say then limit your hours on the screen
but I can't

[thick wind]

Have you tried blue light glasses?

Or if you can afford it, a desktop setup with better frame rate/image latency

[late fulcrum]

Some people do better with CRTs than with LCDs

[dusty citrus]

yeah filtering it out won't work... while for the fps dunno my phone is supposed to be a 120hz while my pc a 165/144hz

[half mauve]

I suppose this has been the experience others have gone through. Are there any other methods of queuing for a Raspberry Pi other than always being on a keyboard, ready to pounce? I received an email an hour ago but by the time I could get to a computer to login, it was out of stock. Do I need to reset anything to get be on the waiting list? Do I have to go to the back of the line?

[dusty citrus]

I gave up

[umbral phoenix]

rss will sometimes realize stock sooner than email 😉 (oops that's for new products)

but there's no way around having to be fast... once it pops in, it's first-come-first-served

[dusty citrus]

I'm lost, octoparts api is paid, reading about it seems like distrubutors such as digikey like to be unfriendly about web scrapers; distrubutors such as digikey do also provide apis which do look like free? do they "daily" change stuff or what?

[thick wind]

Not sure about update rates, but scrapers were a big issue for many when the semiconductor shortage first emerged. Much like the bots that would target newly released consoles or graphics cards, some would use these apis to snatch up precious components and parts like stm32s and raspberry pis.

[blissful roost]

I hope I can get another Pi Zero 2 W when I get paid...

I wanted to get a Pi4, but those are like duck's teeth.

[thick wind]

Aren’t those more limited by supply rather than price? They’re only $15 msrp iirc

[blissful roost]

Exactly

[thick wind]

Skip one meal for a pi zero 2w? Why wait until payday haha

Hard part is finding one, not affording one.

[dusty citrus]

This is my issue.

I’ve essentially given up and will revisit that interest in the future

[thick wind]

As it is everyone else’s haha

I was fortunate enough to snag one early, but I’ve been so worried about breaking it that I haven’t actually used it for anything yet…

Gotta validate everything on my 3b first…

[dusty citrus]

I struggle so hard with “cheaper to buy premade” than to build one usually.

Or “more robust way to do that”

[thick wind]

I just don’t have time anymore. Got exams to study for, on top of my hour-plus commute.

[dusty citrus]

Oh that too

Time is precious and I work a lot

[blissful roost]

I'm not concerned about the money.. I literally can't find stock.

[silver shale]

congrats. cosplay is fun.

did a quick look for chat for help with bluefruit and not seeing one. where do i go?

[stray wind]

What programming language are you intending to use?

[sacred carbon]

not sure. whatever is easiest for making a bluetooth arcade stick controller

[stray wind]

Fair enough. Then you want #help-with-projects. If you don't have a specific language in mind, that's the best place to start with any projects you have in mind.

[sacred carbon]

thanks

[hasty quarry]

Can I assume my tiny 85 is fried or bricked or something if my rig can write to another tiny 85, but it claims this one's signature is 0xffffff?

Or can this be some sort of infuriating fuse or timing error? I have no idea, this seems like it's gone though, but I don't know how to be sure

[late fulcrum]

It could be a fuse, timing, power, or wiring error. For some chips, you need to use "HV" programming to reset certain fuse states. However, 0xffffff could also be a dead chip. I usually haul out my ancient STK500 for those cases, if it can't talk to it, I consider it truly dead.

[static flare]

I should get one of those expensive EEPROM programmers at some point to program my EPROMs

[tardy badger]

Some eeprom can be programmed with an ft232h I believe

[static flare]

I have some vintage EPROMs

[tardy badger]

Oh gotcha, yeah I couldn’t find what I was thinking of to share so it wasn’t going to be helpful even if you were using more modern ones

[late fulcrum]

The TL866 seems pretty versatile and much cheaper than (say) a Data IO programmer.

[gusty torrent]

If the chip is not outright toast I've found with AVRs that its usually EITHER the reset has been fused to enable another attiny gpio or the oscillator has been set to something weird.

[hasty quarry]

I love the ZIF one that Ben Eater uses

[hasty quarry]

Yes this is usually the issue and what I’ve come to first immediately suspect from experience

But a signature of 0xffffff is just downright not okay

[static flare]

same, but they're all so expensive and i have no moneys

[gusty torrent]

I have a ton of old atari 2600 games on 2516/2532 eproms with a homemade zif-socketed cart.

Before the days when flash carts were a thing.

[late fulcrum]

You can always roll your own with an Arduino (or equivalent), power supply, and some drive transistors.

[static flare]

The ol' Ben Eater classic, I might end up doing that just to have something to start off with, I definitely need something to read it anyway

[late fulcrum]

I have a TL866 I bought to try to leverage as a logic chip exerciser, only to realize that a) the chip exercising protocol is undocumented and proprietary, and b) it doesn't give full I/O capability, just a few specific pins.

[static flare]

If only the RP2040 was 5V

Any smaller factor boards that are 5V? (smaller than an Uno)

[tardy badger]

Nano

It’s pretty small, but it’s 8-bit

Not sure if that’s a limiting factor for you

[static flare]

tbh I don't even know, I'd need to come up with a MVP for what i want

Add another project to the project pile

[thick wind]

https://www.adafruit.com/product/2590 is also an option?

There are a lot of arduino variants that come in smaller sizes. Googling arduino mini/micro/nano should give you all the hits you need haha

[ebon dew]

yeah i have a couple metro minis, they're my go to for led projects. was going to try some 5v stuff with circuit python. looks like i got the wrong board :/

will have to go with a logic level shifter

[tardy badger]

Digi-Key has nrf52840 chips available and I has no money to order 🥲

I had thought about making a Bluetooth gamepad with it, would be neat

[ebon dew]

Possible to do 2 player with ble?

Nrf52840 is a great chip for Bluetooth. One of the first things I did with my sense was checkout the Bluetooth stuff. Got it working with my phone like the first time I ever installed circuit Python. Super easy to work with.

Figured you’d be bugging Nordic for those new WiFi chips. With the pico w and Nordic coming soon espressif is going to feel some heat to innovate.

Seems like espressif thinks that means Alexa and Siri replacements… which honestly I’m all for. That’ll take a bite out of Amazon for not improving Alexa for years.

[tardy badger]

Espressif has some WiFi 6 risc-v chips coming, particularly the ESP32-C6 or something like that

https://www.espressif.com/en/products/socs/esp32-c6

[ebon dew]

Cortex m7 might start showing up more too.

[umbral phoenix]

I thought one of these upcoming variants was going to do 5 GHz wi-fi

[ebon dew]

I think that’s part of the thread spec? Or matter? I get them confused.

[tardy badger]

it was supposed to be in their H series but i haven't seen anythin on their website

ah wait, it's the ESP32-C5

https://www.espressif.com/en/news/ESP32-C5

[umbral phoenix]

ah, that was it, but no native USB it looks like

[tardy badger]

yeah, I guess it saves in IP costs

[umbral phoenix]

ugh

[lusty fossil]

Anyone have experience escalating inferior support (app/email) without being unpleasant?

[silver shale]

good thing it was just sulfuric acid and not hydroflouric

[lusty fossil]

Yeah no hobby is important enough to me to mess around with HFA

Dog tooth brush is low key spooky

[tardy badger]

😳

[lusty fossil]

I get strong alien vibes

[rapid geode]

[tardy badger]

I hope someone woke up Green Day

[rapid geode]

?

[static flare]

Wake me up before September ends?

[tardy badger]

When September ends*

[rapid geode]

that was yesterday

[static flare]

Ah

[tardy badger]

Yesterday was the last day of September, once the clicked rolled over to October, September ended lol.

[blissful roost]

Green Who?

[rapid geode]

some old guys that thought the noise they were making was music in the 90s

[tardy badger]

Technically the song came out in the early 2000s

2005

[rapid geode]

doesn't change my assessment

😛

[tardy badger]

Well, I’m happy you have an opinion but I respectfully disagree with it 🙂

[blissful roost]

Music died in the 80's, man... 🤪

[static flare]

Then I was never alive to hear it

[blissful roost]

haha

[tardy badger]

I tend to like a lot of different genres but I gravitate more towards pop, punk rock, and rap

But the Shrek 2 soundtrack was arguably one of the best movie sound tracks and I’ll take no further questions lol

[blissful roost]

I tend to listen more to the quality of the music, rather than focusing on genres.

[tardy badger]

Agreed

[dusty citrus]

btw dunno there's a group touring in my state at September, but dunno if to go or not since the pandemic has not ended (and it's likely to not end anyway)

I kinda don't really enjoy their new album though, too catchy

[rapid geode]

im harvesting all my herbs. 4 sacks of basil, 1 of oregano, one rosemary, one taragon. anyone got a link to how you dry these correctly?

[tardy badger]

My sister dries her herbs in the oven at the lowest temp it can go to spread out in a pan

A dehydrator probably would work better

But if you don’t have one the oven definitely will do the job

[crystal ore]

"Hmmm. What's the right reflow profile for basil?"

[tardy badger]

I’m keeping tabs on my tomatoes which only in the past few weeks started growing well. Hoping to pull some nice almost ripe green tomatoes to slice and fry

[static flare]

I'd definitely recommend against putting anything in a used reflow oven that you intend to eat, however

[rapid geode]

haha

i can use a prooving setting probably. 80-110f or so

hmm. that usually maintains humidity though. gotta check the other settings

i smell like rosemary now.

[blissful roost]

Do love some rosemary. 🙂

I threw some rosemary into the pan with my steak and mushrooms earlier. 😄

[tardy badger]

I've got some rosemary in the garden, rosemary is an annual so it can stay in the ground in most places if it doesn't freeze too hard

i think annual is the right term

[blissful roost]

Yeah.

Shame I don't have a garden any more.

[rapid geode]

house smells like rosemary now

ha

the oven holds the moisture, so i am just opening it to release the vapour every once in a while. seems to be drying nice

[blissful roost]

I wish I had a garden again... Rosemary, Thyme, Basil.. Tomatoes.

[rapid geode]

my thyme got overrun by the taragon, so i didnt harvest it

[tardy badger]

I only had Rosemary and Basil in the garden this year. the Oregano died from the scorching heat

[rapid geode]

2 of the oreganos just flowered. but the other got huge

so i can see this is going to take me several days in the oven to dry everything. but its working, rosemary looks nice

i wish it had a setting to eject steam

this oven doesnt behave with the door open

[rapid geode]

its totally working. i have about 2 jars of rosemary so far (1/3 of my harvest maybe)

woo

just takes a long time

[rapid geode]

100 grams yeild

[rapid geode]

now i got an idea. use the adafruit clue to make a herb dehydrator

ha

[night crescent]

Desk of Ladyada - time for some newNEWnEw designs! https://youtu.be/iMfAyvOQ0-I

[wooden schooner]

Do they make outlet adapters or taps that will convert (one of the receptacles in) this outlet to something that has the usual orientation? Every variation I have tried of "right angle outlet adapter" brings up adapters that go at a right angle along some other axis.

[sullen hazel]

I would just replace the duplex if you are able to

That does not look safe

[wooden schooner]

actually scratch that, they make fancier things like this but they're expensive https://m.media-amazon.com/images/I/61Sn+oiGX1L._AC_SL1500_.jpg

[wooden schooner]

why, because the gfci looks broken?

[sullen hazel]

That, and they will wear out mechanically. I hope that's neutral up but ideally ground should face up

[wooden schooner]

hm. The test and reset buttons appear to work, I think they came inset like that.

the slot on top is indeed neutral. But normally the ground slot is on bottom, right?

[sullen hazel]

I mean the contacts that engage with the blades will lose their ability to hold as the springs wear out. The reason to put ground facing up is in case the outlet starts wearing out gravity will pull the plug out slightly. If ground is facing up and something conductive falls on it you'll be fine, but in the "usual" orientation the live can short to neutral in that scenario. Some municipal codes have been updated to reflect this but code is rarely followed ime

[wooden schooner]

oh wow really? I have rarely seen that orientation

or rather I've seen it but the opposite one is much more common around here

[sullen hazel]

I've seen it more in universities or places that get regular fire marshal inspection. When I worked I'm remodeling we would often have a conversation with the customer about this because people really hate the safer way. I blame power strip manufacturers.

[wooden schooner]

makes sense

[sullen hazel]

My grad school big band rehearsal space had the safe orientation and the keyboardists, guitarists, and bassists all hated it. They would also chain power strips, which is nightmare levels of bad but I'd be lying if I didn't fess up to my workstation being powered off of distributors plugged in to a less than ideal power strip but I do have actual fuses and gfci protection. It's not safe but it's better than nothing. The magic of rental spaces

[wooden schooner]

I'm in a rental space right now, and if the fire marshal came to inspect it, I'd probably have to move out for a month while the landlord fixed all the problems

[sullen hazel]

Are they covering your rent?

[wooden schooner]

I'm not sure what you're asking

I think if the landlord closed the apartment to do repairs, he would be legally required to put me up in a different place, if that's what you mean

[sullen hazel]

Yes

Oh, I misread I didn't realize your comment was a hypothetical

[wooden schooner]

ah yeah i was just making a little quip about how this apartment is not exactly up to code

[acoustic locust]

My landlord has done significant remodeling type repairs (in a nearby building to my own) with the tenant continuing to live there. afaik they did not overnight anyplace else. Long-term tenant, though. They've been in the unit for 15+ years.

I think it's smart to do it that way; it improves the value of the unit should there be a sudden vacancy. If the tenant refuses the landlord just times out the agreement, asks them to move out when it expires (pretty sure I agreed to 45 days on that; 60 days around here is more usual iirc).

Since rents are so high around here, now, it makes sense to stay put if you can.

does exist some sort of free 3d mechanical simulator?

[weary fiber]

If you’re a student, autodesk Inventor’s “assembly” feature is great for previewing mechanical movements

[lean salmon]

is the adafruit website down? I get the following error

[wooden oak]

Im getting that too

[honest jolt]

Yes same on mobile

[lean salmon]

it is back

[umbral phoenix]

I don't know how much that one is, but they make a lot of short (or long) extension cords with rotating plugs so you can orient it however you want ...under $10 usually

[wooden schooner]

yeah, I think if the landlord can keep the units livable while doing repairs they would generally prefer to keep that income

[wooden schooner]

I just want to put an (up-facing) aroma diffuser in that outlet lol

[umbral phoenix]

oh, lol

[wooden schooner]

honestly, running one of those cables straight up and mounting it on the side of the medicine cabinet might be the easiest way

that or asking my landlord to replace the duplex. And while he's at it, make the bathroom safer...

there is also the solution of using a scented candle instead of an electric diffuser, but then that's fire

definitely has its charm though

[umbral phoenix]

fire does have its charm 😉

[wooden schooner]

I think the burning might also eliminate the bad smells in addition to producing the good one? i dunno how smells work exactly

[thick wind]

Honestly, I would’ve just replaced it myself at some point. If you have access to the electrical box and can figure out which breaker turns it off, you should be able to get the parts to swap it out for under $10?

[wooden schooner]

yeah. GFCI outlets appear to be about $12 locally

probably about time I got electrician gloves anyway

@ebon dew re: your comment in #help-with-circuitpython ...I won't use any IoT thing that: (1) requires use of the manufacturer's app, or requires an internet connection, for its basic functions. I only allow IoT things of my own making to directly access the internet 🙂

I've made two exceptions, both hardwired ethernet, each on its own VLAN with nothing else 😉

[ebon dew]

Neradoc brought up a good point. Can only do but so much when you’re the one connecting the iot device to your pc. Web workflow will make things easier but less secure even for people with good firewall management. It always comes down to security vs convenience.

[wooden schooner]

Abolish IoT

(😛)

(but with a seed of truth)

[tardy badger]

Unfortunately a majority of people want convenience

[ebon dew]

I’ve been working on replicating Becky stern’s social media tracker with 7 segment displays. Her project uses NodeMCU. I have my doubts about anything intentionally named node. So I decided to go with an Adafruit board instead and circuit Python. For microcontroller projects the biggest choice is the board itself. I trust Adafruit and that’s why they get my business first.

Yeah but then I wouldn’t be able to log hurricane data on adafruitio which I’ve thoroughly enjoyed. 😁

[umbral phoenix]

If you can't trust your own LAN, it does make things much harder

[ebon dew]

Have to trust yourself first and I can’t even do that sometimes. 😣

[umbral phoenix]

lol that's true

[ebon dew]

Oh for sure. There’s always post editing. I like to show mistakes, highlight them even, as things not to do. Part of becoming proficient is doing all the wrong things eventually and then never doing the wrong things again. Like, part of experience and mastery is doing things wrong.

[tepid tide]

I am trying to create a USB passthrough device using two Pi Picos connected over serial. Would I be able to solder full female header set on one, full male header set on the other, then just snap them together like LEGO?

[thick wind]

The only issue I see with that would be the lack of wire crossing for hardware uart. You would either have to wire a serial connection manually, or configure a software or PIO-based uart on one side to switch the pins.

You would also have to be very careful about driving other pins, as two pins with opposite outputs could cause some permanent damage somewhere.

[tepid tide]

right of course, so 3V3 out connected to each other would be bad

[thick wind]

Well, two pins at the same constant voltage is fine

It’s more an issue if you have a high and a low on the same IO pin.

Theoretically it is possible, but it may require some careful engineering of two separate firmwares.

[fossil scaffold]

I've recently discovered the magic of wirewrapping and how much faster it is to make connections on protoboards that lack traces.

If you make a lot of protoboards with through-hole components then it's definitely a good method.

[subtle grotto]

anyone know if I can store data in a variable on an arduino, then plug it into my computer and somehow take the data from there?

i think i may need to have it already connected to the computer and print to the console, or at least have an SD-card onboard while I take the data and print it to a .txt file there, but i am unsure

[umbral phoenix]

@unkempt nimbus can you redact the grades and other personal info?

[thick wind]

In a variable? Sure, as long as you write a function to write that data from your memory to either a file on a Micro SD, or send it to a serial client with Serial.print()?

Although an arduino may reset on a usb connection…?

If you have a nonvolatile storage like a micro sd it should be fine.

[unkempt nimbus]

Not sure, you could just try it and see what they say - they also accept an ID card with your name and school name, which wouldn’t have as much identifying info

[subtle grotto]

@thick wind is the microSD plugged into the computer or the arduino?

[thick wind]

It would have to be plugged into the arduino in order for the arduino to be able to write to it.

[subtle grotto]

alrighty, thank you!

[thick wind]

Some microcontrollers with built in file systems may be able to store the data directly, but I don’t think an Arduino has that functionality. Don’t quote me on that, as I’m not familiar with all the arduino variants these days…

[subtle grotto]

yeah i agree, i thought you'd give me that answer i just wanted a second opinion. thank yoU!

[whole jacinth]

some of the Adafruit Express boards have extra flash on board, which might be accessible from an Arduino API. (though i think the recommendation might still be to install CircuitPython briefly to get that flash initially formatted as a filesystem)

[thick wind]

I know esp32 has SPIFFS which allows you to store files directly to the internal flash. The nice part about that is you can even setup a mini http server to pull data over Wi-Fi.

[wooden schooner]

It seems like gloves that are branded as "Electrician Work Gloves" conspicuously do not make any claims about electrical insulation. For example:
https://www.homedepot.com/p/Klein-Tools-Extra-Large-Electrician-s-Work-Gloves-40074/203410374
Presumably this is for liability reasons. But then it seems like "electrician" gloves have no advantage over other work gloves, right? For simple things like replacing a receptacle (while the breaker is thrown of course), should I just use any old leather work gloves?

even "lineman gloves" make no claims about anything electrical: https://www.homedepot.com/p/Lineman-Work-Glove-Large-40082/203480716

the standard advice (which electricians don't follow) seems to be rubber gloves on bottom to insulate, and leather gloves on top to protect the rubber gloves from wear and tear

[burnt tendon]

I mean, there's some lineworker video bloggers on youtube and they are using actual rubber gloves to insulate and all.

Then again, they are working on high voltage lines and that's a different thing than household current.

[tardy badger]

Line workers also use rubber line mats too

[dusty citrus]

indeed
I mean probably you could fake that
but I don't want to deal with such thing

[wooden schooner]

Yeah, it looks like there is nothing physically special about lineman gloves compared to, say, the rugged gloves I use to wash dishes -- seems like the reason gloves that are sold as insulation are rare is that they have to then be on a semiannual inspection and recertification schedule.

I think I found a broken problem in my calculus unit about u-substitution

I always welcome a challenge though, that was pretty funny

I think they omitted an “x” outside the root

[wooden schooner]

wow... here's what the old receptacle looked like

its load connections are taped over, and there's a wire nut joining all three neutrals and another joining all three hots. smooth.

afaik it's electrically equivalent [edit: no], but like come on, why not use the safety + organizational tools available to you.

[rapid geode]

3 in one is fine. tape not so much

i use push fittings now. which allow up to 4 per connection

[wooden schooner]

yeah i mean, what you lose is the ability to easily know which is which

I'm not saying the wire nut is overloaded, I'm saying the receptacle has separate connections for line and load, please use them

[rapid geode]

ah

[wooden schooner]

also re-lol, after installing the new receptacle i realized that the aroma diffuser can rotate to fit the old receptacle's orientation

but hey, now I know how to install an outlet and also my apartment is one smidgen safer

[umbral phoenix]

learning AND safety... what could be better

[wooden schooner]

plus, I learned that this GFCI is not prior to the light on the medicine cabinet, which means that that medicine cabinet could have easily been protected per code but just wasn't. Instead, the GFCI is in series with the window AC in the neighboring bedroom.

that seems like a lot, given taiwan does plastics and metal working that used high heat.

i guess we need lots of chips

yea lol

and if Im reading that correctly, 99% of their energy is imported

I think that means coal powered stations

[wooden schooner]

nope, wanted it upright so that I can plug in an aroma diffuser. Old receptacle was sideways.

and the diffuser only rotates 90 degrees in one direction

[rapid geode]

oh

[burnt tendon]

Well, that stinks.

[wooden schooner]

wait, it's not electrically equivalent. With the old wiring, downstream loads are not protected by the GFCI.

I have some exciting news to share and wanted to thank @night crescent and specifically @stuck moth for helping me get started with my contributions to atsamd-rs by supplying dev boards and info about atsamd chips

The news is: Volvo is using atsamd-rs in their next generation electric vehicles!
https://medium.com/volvo-cars-engineering/why-volvo-thinks-you-should-have-rust-in-your-car-4320bd639e09

feel free to add to the adafruit blog or w/e

also: maybe we know where all the chips are going? 😛

[late fulcrum]

That seems like a good idea to me. Especially after the Toyota disaster

[lusty fossil]

What happened?

[late fulcrum]

It started with some mentions of "unintended acceleration", which was originally attributed to malfunctions in the throttle sensor possibly due to tin whiskers. However, a series of claimed fixes didn't remedy the problem, and eventually investigators obtained the source code and found it was a giant steaming mess.

[lusty fossil]

Ahh

There was a Malcolm Gladwell bit on that but it started my suspicions that he's overblown.

He claimed it was the floor mats getting stuck on the pedals, caused by unsure drivers.

Seemed a stretch to me.

[late fulcrum]

There were a lot of possible explanations, which may or may not be terribly relevant. It's entirely possible a floor mat issue was responsible in a few cases, I have no idea.

[lusty fossil]

Yeah

It seemed unlikely to me to be responsible for all of the cases

How would Rust help?

[burnt tendon]

My dad was an aeronautical engineer and part of one of his vague rants was that aircraft engines generally had multiple independent strings of control for safety-critical systems like the engine controller. And I looked and, of course, the car engine controller didn't have independent strings of control, it just had some vague handwavey idea about multiple processes or something.

So, you had the code being a steaming mess, the floor mats being not well designed to stay stuck no matter how silly the driver is, potentially other safety issues in the engine controller, people confusing pedals, and it not being trivially obvious how to kill-switch the motor in cars that had just switched from a mechanical key to a button.

[vernal gale]

rust isn't a panacea for all problems, which the article acknowledges, but I'm excited they're using something I worked on

[burnt tendon]

Yeah, there's a lot of problems that Rust solves nicely.

[granite whale]

[glass tendon]

Hey is there any idea where there are going to be more Feather M4? or at least an equivalent one?

[lusty fossil]

Nobody knows as far as I know

It depends on when new stock of the chip comes in and if adafruit can get some

[umbral phoenix]

had some recently, but gone now @glass tendon are you looking for feather, or more for M4, or certain features?

[glass tendon]

I was waiting until I got paid and then I was going to buy one but I was too late.
I was just suggested the M4 Express for my project.
I am building the portal gun from Portal and I want different light modes and sound

[umbral phoenix]

has other Adafruit M4 boards (e.g., Itsy Bitsy, Grand Central)

has Itsy Bitsy M4... that's a nice board... smaller, and you can add a small battery charger https://www.adafruit.com/product/2124

I haven't checked it against any portal gun guides to see it isn't missing something

oh, no I2S, it's the smaller chip compared to the Feather M4

(Itsy Bitsy ATSAMD51G19 vs. Feather ATSAMD51J19)

[glass tendon]

I apologize but all this is going over my head. I have no idea what you are talking about. This is my first time ever doing something like this

[umbral phoenix]

OK, sorry, are you working from some tutorial that outlines what features are needed?

[glass tendon]

I also would like to use one of my own battery. I have a few 5v portable chargers I want to use.
So for features I just need it to change the light color the plan I have is
1 button press = swap between blue and orange
2 button presses = white
3 button presses = rgb Carmelldancen
I would also like sound

With the 1st button I want the normal portal firing sound and with 3rd the carmelldancen song

[umbral phoenix]

adding buttons and using an onboard or external RGB pixel(s) for the colors is pretty straightforward

One issue with some USB battery packs is that they turn off if not much current is flowing. There are some that don't, and there are dongles that keep it alive if it does. Something to explore.

Someone else should chime in about sound questions, it depends in part on the quality and complexity of sounds you want.

[glass tendon]

What is the dongle I need?
Also what do you mean by complexity?

[lusty fossil]

Sound is weird

[umbral phoenix]

first I'd test the battery pack or look up its specs to see whether it turns off with low current

[lusty fossil]

If you want horrifying wailing sounds, it's easy peasy. If you want something recognizable and good sounding, it's a lot harder

I'd do some reasarch and see if you really need the M4.

[glass tendon]

How do I test that?

This is the main sound I need

https://www.youtube.com/watch?v=A67ZkAd1wmI
This is the meme song I want to use with the rgb

[umbral phoenix]

I think there are a variety of little add-onm to keep a battery pack alive, I have this one: https://www.crowdsupply.com/pichanon-suwannathada/powerever

but try it first on a real board (or if the specs are clear about it)

[lusty fossil]

How compact where you hoping to make the electronics?

[glass tendon]

Space is not really a concern

[lusty fossil]

Ok

What's the project timeline?

[glass tendon]

the end of this month

[lusty fossil]

Ah ok. Well. There is a board called the DFPlayerMini from DFRobot that may be beneficial. I am slowly working on a circuitpython library for it when I'm not working on other stuff. That said I could get you rudimentary support before the end of the month.

If you can use arduino there's already a library for it.

You'd need an SD card and SD card reader

[glass tendon]

I have no idea what most of that means. I have an Arduino uno but I have never used it

[lusty fossil]

Hm ok

Well both are programming languages that can be used on the boards adafruit sells. If this is your first time programming, circuitpython might be a bit easier to deal with.

[glass tendon]

I have a little bit of experience in python. Is it possible to use the Uno to do this project?

[lusty fossil]

In arduino almost certainly. In Python definitely not

Arduinos not that hard to pick up. We have lots of qualified folks here who can assist.

[lusty fossil]

This is because python requires a lot of resources whereas arduino far far fewer

[glass tendon]

I might go the arduino route if I can do everything I want

[lusty fossil]

You can

Both languages have pros and cons

Also pretty much any adafruit board will be really more than enough power and space for arduino

Arduino is just a slightly flavored C++

[glass tendon]

So wait I am unable to just use the Uno for this?

[thick wind]

I think having a couple neopixels on should keep it alive. Can’t really do a low power mode with a battery bank but probably fine for a prop.

[umbral phoenix]

yeah, just depends on the pack, and the draw

[thick wind]

It’s not impossible, the only tricky part in software would be audio. I know there are other peripherals you can choose from to simplify that, so the other challenge would be making it all fit inside, as an unit is a lot larger physically than a feather.

[lusty fossil]

I suggested the DFRobot DFPlayerMini. I'd also suggest either a feather or qtPY m0

The last two are adafruit projects

Because really this project only needs 3 gpio as I understand. 2 for uart and one for neopixels

2 for uart if you use the dfplayer mini

The qtpy is quite a bit smaller than the feather which is a nice feature. And comes with UsB C

[thick wind]

https://www.adafruit.com/product/1788 is a bit pricey, but it’s be my go-to for an arduino uno?

[glass tendon]

for size reference this is what I have

[lusty fossil]

Yeah I thought about that @thick wind but it's quite expensive. I guess if you're set on using the uno.

From what I've read, the chip on it is quite nice though

[thick wind]

Feather Rp2040, max98357 amp breakout, and a speaker combined is cheaper than that

[thick wind]

Yeah I was busy looking up the names, typing on phone is slow gosh darn it

[glass tendon]

Okay so I guess what is the fastest thing I can do to get my electronics complete?

[lusty fossil]

You need somewhere to store the mp3, no.

[thick wind]

Whichever has faster shipping, I guess?

[glass tendon]

I dont know what board to get though. I am not really understanding

[thick wind]

And depends how many minutes of mp3, I believe you can store a couple of MP3’s on a Feather Rp2040

[lusty fossil]

Sorry. We've been talking kind of high level

[thick wind]

Any preference in supplier? Shipping takes time too, after all.

[glass tendon]

one is about 1 second and the other is about 3 minutes

and I don't have a prefrence

I just want to make this my best project yet as portal 2 is my favorite game and since the first game is getting an rtx upgrade

[static flare]

Good luck! I'd love to see what you end up with, I love Portal 2, it is also my favourite game

[gusty torrent]

Digikey is ridiculously fast. They get stuff from midwest US to my doorstep in Tokyo in 2 days.

And they'll have most Adafruit products too

[thick wind]

Oh. If cost isn’t an issue, I’m pretty sure https://www.adafruit.com/product/4300 can be used as a substitute for a feather m4 @glass tendon

Not sure if you need the prop maker with this, either, as it has an amp onboard

[glass tendon]

Although it does have an lcd screen that I don't need it could use

[thick wind]

You can use it for a user display if you have time to develop it haha

https://www.adafruit.com/product/3919 for more light, and pick a lipo battery for power

[glass tendon]

What is going to be the most simple thing for me to do in order to get this project done this month?
Is this something I can use?
https://www.adafruit.com/product/4064

[thick wind]

It’s a bit bigger and not as convenient as the hallowing

I think the hallowing gets bonus points for have the audio driver and connectors

But if you’re comfortable adding and wiring your own amplifier and neopixels, it’s certainly a valid option.

For the same price, I think the hallowing option is nicer, as you’re building a prop with limited space and not in need of all those extra outputs.

[static flare]

If I were going purely off of doing it well and fully, I'd probably go with a Feather RP2040, and a Prop-Maker Wing

[thick wind]

I would argue that as the budget option, as RP2040 PWM audio just isn’t as nice as the 12-bit DAC on the SAMD51.

The hallowing has almost everything the feather M4 propmaker combo offers, main difference being onboard Tft vs slim feather form factor.

Hello, Thanks for the product suggestion - we will share this with our teams. Thanks, Adafruit support, Kelly

Anything in low volumes are typically not cheap, but exceptions can be made for something that’s not overly complex?

[half plank]

@rapid geode was asking

[thick wind]

Definitely possible but not something that gets essentially printed out of a machine, so some hand labor tends to have costs associated with it.

[half plank]

To be fair, I wasn't committed to making one, it is a cool idea but I have way too many unfinished projects at the moment.

[half plank]

[ebon dew]

I heard the S2 and S3 can drive a display directly but was unsure if there was a resolution/size limit. This should be really cool news if they found a way to directly drive large displays... 40 pin featherwing? I'd buy one.

[halcyon furnace]

Hey, are there are guides for building UF2 for a new board based on ESP32-S2 feather?

[ebon dew]

link?

This one looks like it's based on SAMD boards https://learn.adafruit.com/how-to-add-a-new-board-to-circuitpython/get-setup-to-add-your-board

ohhh i think i misunderstood your question. you're asking if there are guides specifically for an ESP32-S2 feather? I don't think so. The board honestly doesn't matter. If you want an example of previously contributed boards then poke through the ports/espressif/boards section for the s2. https://github.com/adafruit/circuitpython/tree/main/ports/espressif/boards

[halcyon furnace]

Something that's based off the ESP32-S2, not necessarily a feather, though I'm using a feather reference design

I think it uses the TinyUF2 bootloader but haven't found much in terms of how to change it for a new board

Actually, STIR/SHAKEN is dependent upon the provider, not the battery.

Is anyone else getting 500 for anything on learn.adafruit.com?

Pro tip: locahost is probably wrong.

what would be the best mesument to observe for a bike crash acceleration on x y z or xyz axis change

[thick wind]

No idea, but please do not post the same question in multiple channels in a short period of time.

[half plank]

Hem, I would like you to know that I just joined the server two days ago and never knew that. I am so sorry!

[thick wind]

No worries, just letting you know. It’s not a direct violation of the code of conduct or anything, it just helps any relevant discussions stay together in one place.

If you don’t get a response immediately, don’t fret. This is a community where everyone has time zone differences and other commitments, but if someone has an answer, you should get one eventually.

[half plank]

Ok thank you. Just to let you know after some testing the best way to make a bike crash is the deceleration and acceleration of the z axis

[lusty fossil]

Any Australians here? I love EEVBlog but I don't know what he means when he says "X is a bit How Ya Doin'"

[blissful roost]

Dodgy, shifty, a wee bit suspect.

Thankfully, Aussie slang is pretty close to British slang. Lol

Summary: Not good, unreliable, untrustworthy.

How do you use the adafruiut library for oled and print text then erase it and then write new text?

[hard mica]

Is this Arduino or CircuitPython?

[half plank]

arduino

[fair summit]

#help-with-arduino is then the best place to ask

[half plank]

ok thank you

[fair summit]

also search in https://forums.adafruit.com as someone may have already asked the q

there may be examples in the library you can use

howdy!

heya!

[odd heath]

is the fluid that comes out of a supercapacitor caustic

need answer quick

[burnt tendon]

Assume it is.

[odd heath]

ye

I've already rinsed and washed my hands aggressively

gonna keep doing that for coup minutes

ok, seems good

[ebon dew]

it's battery acid, good wash and you'll be ok

A QT Py RP2040 "W" would be awesome, too bad the Infineon module is so big. The RP2040 QT Py is already pretty busy on both sides.

But Feathers don't have a length spec, as long as the width and pins are right, maybe the QT Py could be extended a little. A u.FL connector too, while I'm dreaming 😉

[thick wind]

From your experience, what are the most significant pros and cons working with a pico w vs an esp32? I’ve yet to buy a pico w for myself and was wondering if it’s worth exploring now or something I can put off for a bit…

[umbral phoenix]

I'm probably not the best one to ask. I'm all about the wifi, and focus on CircuitPython, and I like having options - they both use the same CircuitPython API so code written for one can run on the other (pin names aside). ESP32-S2 vs. Pico W? Pico W is dirt cheap and has PIO (though I haven't used it), but ESP32-S2 (in the right configs) has tons of RAM and potentially tons of flash. I'm sure we'll see more variants of the Pico W over time with more flash.

Having two popular wifi platforms is better in the long run I think. It may be a couple of years before there's a new, faster, higher-resourced RP2xxx, but I'm hopeful. ESP32-S3 is out and very capable.

I don't get the point
on kicad, eschema, why am I placing symbols which then need to be associated with a footprint?
why isn't it made by default in one click?

[crystal ore]

Well, there's not necessarily a 1:1 relationship. A transistor symbol might be associated with a bunch of different parts and footprints, for example.

[lone yew]

Depends; sometimes symbols will have a default footprint assigned already (e.g. if you choose something specific like a 2N2904 transistor). For parts with all kinds of footprints, like capacitors, there's no way it can guess

The more specific the part you choose in the schematic, the more likely it'll have the right footprint assigned by default

[orchid zephyr]

I just had a funny idea

Imagine if regular consumer pc mobos gave you direct access to like 15 or so cpu pins as gpio

Still a regular intel or amd or whatever cpu, just with a few pins reserved for something custom

On one hand: stupid fast and overpowered microprocessors (modern cpus are just overgrown microprocessors anyway)
On the other hand: stupid easy property damage

asm OUT go brrrr

[thick wind]

Not so much GPIO on a CPU, but you could technically achieve something similar with a mircocontroller or FPGA in a PCIE port?

[orchid zephyr]

Absolutely, however, that’s a legitimate, practical idea

And mine is not

Lol

[dusty citrus]

I’m way late to this. But is python>circuit python an accurate statement?

[umbral phoenix]

depends what you mean by “>”

CircuitPython shares syntax, but is a subset due to limited resources on microcontrollers, but also has built-in modules specific to microcontrollers that CPython (desktop python) doesn’t have (or need)

Shame I sold mine. 😦

[crystal ore]

What a bizarre coincidence. I just booted my BeBox back up the other day. Still worked, and the clock battery still knew what day it was, even.

It was harder to pull files off of it than I expected, since I forgot it didn't have any USB ports. 😅
