Hey guys, on the 2-factor sign-in deal, as far as I read the setup procedure, I must have a "smart" phone that can read a QR code, and neither my wife or I have one. True? Thanks.

looks like U2F security key (for computer) might still be supported (but not SMS)

oh, but it requires a previous 2FA setup of some other kind?

random question but does anyone know about nitrile O rings and IPA

if IPA will destroy the O Rings

i ordered 2k o rings

and i want to build a mini engine cause bored

but i need the o rings to seal the fuel lines without them breaking

[fair summit]

websearch < nitrile o-rings isopropyl alcohol > ; lots of compatibility charts; tldr: could be better

[sick apex]

OH YEAH HAHA

i forgot google exists

😭

[late fulcrum]

I would suspect it wouldn't be a problem, especially if you lubricate the o-rings with silicone grease.

I have moved house!

[rapid geode]

i tried to move my house once. too heavy. need a bigger forklift.

[tardy badger]

And to be fork lift certified

[rapid geode]

a wee box building for my cnc stuff. city said im allowed to add a new one. (already have one nicer shed)

trying to figure out if i can do it really cheap and fast. i found a used garage door for $400, designing around that.

[whole plover]

Nice shed!

[rapid geode]

thanks. too bad its too cold and nasty now to build it. might need to wait til spring

I am participating in the circuitpython-dev channel. I find it hard to interact because all of the “GitHub BOT” posts.
Is there a way to mute the bot?

[rapid geode]

can you put the "user" on ignore? not ideal i guess. but might work. i just checked there and see what you mean. its 80% git bot

[ebon dew]

there usually isn't much conversation in the dev channel. a lot of it is done on their slack or github comments. the dev channel is definitely where new board devs should go for build help. just ignore the github bot updates if you're not interested in reading about the latest developments.

[astral basin]

@ebon dew - it can be quite difficult to ignore so many posts and to find the humans. There are a few contributors who try hard to help those of us looking for assistance.

The bot traffic really should be its own channel - perhaps we could request a new channel “circuitpython-dev-help” for humans.

[whole jacinth]

i've seen other projects put the github bot traffic into its own channel, and it seems to work well

[umbral phoenix]

sometimes devs comment in the channel about one of the gitbot posts

like, clarifying info about an issue or PR

I can see why it's there, those bot items are the core of the work for many of the folks who hang out there

[astral basin]

Commenting on BOT content is fine but there is legitimate and valuable human content that is getting seriously lost in the bot noise.

TBF: I got my answers and can leave it all behind … but I fell badly for the next bloke who needs help like I did.

If there is a desire for board makers to add CircuitPython support for their hardware, then I would suggest “help-with-circuitpython-dev”

[astral basin]

@stuck moth - I often find myself needing a weed whacker 😜

[pliant plover]

Not trying to sound like a PITA - I appreciate that Adafruit at least requires 2FA for high demand items, but can you ~~guys ~~ folks (who said an old wolf cant learn new words?) consider implementing a captcha for the checkout process of items that are frequently scalped? By the time I had generated my 2FA code the RPI5 stock went from something to nothing and it's just incredibly frustrating because I need to evaluate the feasibility and cost of porting a RTOS to the Pi 5 vs just using legacy hardware or a different SoC/SoM - meanwhile most of these units are being put on eBay.

And it's plain as day that the issue is botting more than anything.

I had the same exact problem on Digikey as well, where the stock went from 600 to 0 by the time I got to the payment page.

[late fulcrum]

The usual approach to this is a timed cart: once something is placed in a cart, it is "reserved" by that buyer as long as they check out in a specified period of time. However, implementing this is somewhat complicated.

[burnt tendon]

I think it's the product of a deranged serial killer.

[stuck moth]

some password managers can manage 2fa for you as well (I know 1 password does). That'd make it faster to generate and enter upon login.

[pliant plover]

I mean, I could also just set something up to refresh the page every few seconds and generate the 2FA as well, and check out if it's in stock.

Maybe I should. Seems like the only way I'll ever get one at MSRP .

Then I could even continue doing it, sell them on eBay and frustrate someone else who needs one.

My point though is the fact that people have these automated systems hammering it, and most of them are just reselling them.

A story old as time.

[stuck moth]

Please don't. That behavior leads to bans from Adafruit.

Are you waiting for an email about a restock or doing it during a livestream?

[pliant plover]

No. I just sometimes refresh the product page and hope for the best.

Anything beyond that requires far too much effort.

[stuck moth]

I'm pretty sure they are putting them in stock during ask an engineer

[pliant plover]

I will check it out. Thank you.

Thank you! - this refers to cutting D10 trace on Airlift shield, and jumper wire to D3 for CS, which does not now conflict with a TFT shield on top. 😀 Testing on Metro M4.
Update: cutting Airlift D10->CS trace deactivates D10 completely, don't know why. After trial and error, I jumpered the TFT D2 pin to it's D10 pin, and TFT works fine with TFT CS set to D2.
I pulled out my trusty blink LED tester hooked to D10, no power anymore. Mystery to me.

Does anyone have a good YouTube video on explaining in detail how to do SMT soldering the correct way for complete beginners? I find lot of video that are just bragging but not explaining 🙂

[tardy badger]

It might not be super explanatory but I learned a bit by watching how Lady Ada did her prototype builds for boards. There are a number of videos that Adafruit has posted that of product buildup and testing

[stoic mesa]

it also very much depends on which components you plan to use. If you only use 1206/0805 parts and SO packages (which have 1.27 mm pitch), it is not that hard, even for a beginner (but of course, be prepared to ruin several boards before you get the hang of it).

If you plan to use TQFN/TQFP packages, with 0.5mm pitch, it is much harder.

[urban cedar]

So I have this problem with adafruit who is forcing me to pay VAT taxes, then keeps the money for itself, not even attempting to forward the money to the relevant govt agency. So of course when shipments arrive, I have to pay this VAT tax, in effect paying it twice, then beg adafruit to refund the taxes who then wants me to prove I paid it again... This isn't exactly good business ethos to pretend you collect money for a govt agency then keep it until customer begs for it. Support is helping with refund, but this needs to be fixed, unless it is a deliberate business practice...

How to reach out to someone willing to fix this problem?

[stuck moth]

support@ is the correct place

[urban cedar]

I thought it was, I explained the problem at length weeks ago and yet was again hit with the same problem this week... support isn't answering whether the problem is being looked into, just willing to help with the remediation (refund).

[stuck moth]

Refunds can be cheaper than expensive dev time

[urban cedar]

well, since you are refunding money you collected for absolutely no service or product provided, it can even make a profit if some customers don't ask for a refund

great business perspective...

@trim sandal - I see a lot of people hand soldering SMT and I give them credit. I found using paste and a stencil to be infinitely easier for me. I do all my prototypes that way and I “reflow” using a cheap hotplate.

[trim sandal]

Great didn’t know about this

[crisp lantern]

Hey guys - I'm trying to repair a turntable for my mother, recently got into electronics repair, got a whole little station going etc.

I have this motor that wasn't working properly, I think it might be the motor controller circuit thing

https://www.alldatasheet.com/datasheet-pdf/pdf/13414/PANASONIC/AN6652.html

Is there a way to test it to see if it's indeed dead?

The DC motor spins when I apply 12v with my voltage injection tool.

The capacitor in that circuit is also good.

[crisp lantern]

Oop, nevermind, figured it out. Inject 14v at VCC then check motor for 12v, which it has. Hmm

[late fulcrum]

That's how you do it, try to narrow down things with hypotheses and experiments

[quaint marsh]

The motor is often controlled by both a start/stop button and the tone arm (swing the tone arm over the record and the motor starts). Maybe it’s a simple fault at one of those switches.

Also: you said the motor wasn’t working properly- what specifically was wrong?

[crisp lantern]

So in this unit, the on/off switch is within the tone arm itself apparently, although I was unable to get it working still.

The motor just doesn't spin even though it's getting 10.8v. It must not be receiving some kind of signal it needs to turn on.

I tore a trace off by accident when reinstalling the regulator but fixed it using some wire under the microscope.

As dodgy as it looks, when using my voltage injection tool, I can get the motor to spin as intended, even after the repair.

[crisp lantern]

at the end when I was giving up, I decided to try to reflow the board using hot air

then I heard what sound liked popcorns popping a few times, I didn't see anything, maybe it was just the board cracking with the heat

but I'm wondering if some of those tiny square capacitors popped

[vestal plume]

Hi, has anyone done the math or more likely read something about 8bit controller vs 32 bit controller. Meaning the time difference between giving 32 bit controller a 32 bit operation and than giving the 8 bit controller same 32 bit operation

[fossil dawn]

I think it probably depends on what exact microcontrollers and what exact instruction you're thinking about

#include <stdint.h>
int main(){
    volatile uint32_t a = 10;
    volatile uint32_t b = 5;
    volatile uint32_t c = a + b;
}

(I will only paste the assembly here for the line with the actual addition.)

https://godbolt.org/

ARM GCC 13.2 (32-bit)

        ldr     r2, [r7, #12]
        .loc 1 8 31
        ldr     r3, [r7, #8]
        .loc 1 8 29
        add     r3, r3, r2
        .loc 1 8 31
        str     r3, [r7, #4]
        .loc 1 9 1

I think the .loc are just some debugging stuff. But you can see there are two ldr load instructions, one add and then one store.

AVR GCC 13.2 (8 bit)

//load a:
        ldd r20,Y+1
        ldd r21,Y+2
        ldd r22,Y+3
        ldd r23,Y+4
        .loc 1 8 31
//load b:
        ldd r24,Y+5
        ldd r25,Y+6
        ldd r26,Y+7
        ldd r27,Y+8
        .loc 1 8 29
//add:
        add r24,r20
        adc r25,r21
        adc r26,r22
        adc r27,r23
        .loc 1 8 31
//store result:
        std Y+9,r24
        std Y+10,r25
        std Y+11,r26
        std Y+12,r27

As we can see here, it takes 4 instructions to load a, 4 instructions to load b, 4 instructions to add and then 4 instructions to store the result

On AVR there's the "AVR instruction set manual" that tells you how long each instruction takes. I would assume that there is something similar on ARM.
For example, on an Atmega328P the ldd instructions would take 2 clock cycles each, then add and adc take 1 each and std take 2 each again.

Afaik other stuff like multiplication, division (how long that takes) also depends on the MCU and what its hardware can do.
Same thing with flash access.
Also, the 32 bit MCU might just be clocked way faster than the 8 bit one

@vestal plume

https://developer.arm.com/documentation/ddi0432/c/programmers-model/instruction-set-summary Ah here it is for ARM cortex M0+ as an example.
Each ldr takes two clock cycles. The add 1 and the str 2 again.

So way faster 😆

[dusty citrus]

On factories are rj45 seriously all crimped by labour? All I can find is about it.

[late fulcrum]

Probably solder flux boiling, that's common

[dusty citrus]

What do you mean?

I mean how are cables even displaced in the right position before being soldered/crimped?

[rapid geode]

they have robots for all that. cut, strip, spread, crimp. all in about 100 milliseconds probably

there might be special connectors for 'machine" crimping vs hand as well that make the process easier

[mental bane]

anyone got free time?

I have no idea how to fix my pico

yes you have seen me before asking this before and yes it's been about a week stuck on this

and yes I have become desperate to just ask like a loser in a discord chat.

[sick apex]

does anyone have a good way of writing some code kinda like server and client where an esp32 for example can resolve an IP from a desktop server

like if i wrote some code into an app on my PC that hosted a lil server and then i connect the ESP32s to my network running the right code, to get them to find the server

cause i dont want to make it so you have to hard code an IP into the library

so far i have this but obviously it will run a small server

any compliant esps or picos or whatever need to find out where this server lives on the network

idk if im making sense

i know truenas core manages to make a domain name on the network but i dont know how to do that and it seems a lil too cumbersome and it could be blocked by firewalls and such

for extra info, it's kinda like a management system for ur networked devices, you can make custom function types that will be pushed as buttons to the management panel

so you'd set it up with some info like device name, maybe a category or something

and then you can create kinda like FreeRTOS tasks but not really

like a freeRTOS task but in a wrapper

which will show up as a button

so you can terminate devices, pause their processing, check data

have anything upload itself to the panel into it's own lil section

[patent hemlock]

there is an existing protocol called "DHCP" that does this

[sick apex]

dhcp assigns an IP address

[tardy badger]

My brain is so used to DHCP being in the context of “dhcp server” and I had to think for a moment like “dhcp is a protocol?”

[sick apex]

doesn't give you the location of an unknown server that you only know the port for

yes yes it is

[tardy badger]

I’m aware it is, I just never think of it in that context

Anyway, trying to find servers based solely on ports seems a bit too ambiguous to be useful

[sick apex]

yeah it's like http though

when ur speaking you dont say use the http you say use the http protocol

[fossil dawn]

is that mdns? 🤔 That's also used by for example spotify to find devices in the local network

[dusty citrus]

You can set specific ips within the dhcp, or make an association using the mac adress if that's what you're asking , I am not familiar with freertos

Or are you asking about the physical location of the device?

[jagged citrus]

Ladies and gentlemen, my 2009 dell pc, has unfortunately passed away

It no longer werks

[summer sand]

I am sorry for your loss

[pastel steppe]

so simple lol - might try to put it into a gameboy-like housing or something

[jagged citrus]

AAAAH

Please put a heatsink

[pastel steppe]

Right that was my next question, on the metal part or on that black part haha

[jagged citrus]

On the black part

[pastel steppe]

While testing it didn’t seem to heat up at all, but I do have a heat sink

Gotcha thank u

[jagged citrus]

Thats the SoC

The silver part is a shield that covers the wifi chip

[pastel steppe]

Ohhhh good to know

Funny enough I assumed it was the other way around

And this is for rasp pi zero 2 correct? Idk if the other models have a different configuration on the board

[jagged citrus]

Yes

[pastel steppe]

Awesome thank u

[jagged citrus]

Np

[sick apex]

i used discovery packets

it worked

but for some reason when i implement it into the actual GUI app

everything breaks

visual studio throws 10000000 errors

[fossil dawn]

what's that?

[sick apex]

basically you just ping the broadcast address on a port and wait for a response

obviously im going to be more secure and require some authentication

before you can chat to the server

but it's all i could think of

and it worked

and everybody who has ever done C++ networking knows

it's a pain in the backside

[fossil dawn]

so a custom thing? Or some established protocol?

[fossil dawn]

networking more like notworking 😝

[sick apex]

RIGHTTT

[sick apex]

it's pretty typical

it's not really a protocol

sort of is

the last entry in your subnet is a broadcast address

which the switch will send the packet to every device

and if you have a server setup to listen on that port

and reply

then you can find the right IP

i mean i could have used ARP and made you hard code a mac address but i think thats icky

hardcoding anything besides ports is icky

[fossil dawn]

ah, nice

I thought there definitely have to be some sort of standardized protocols for this kind of thing but no idea if using them would give any benefit since only your own software needs to understand it anyway 🤔

[sick apex]

yeah i mean im using the in house port range

but im gunna make it customisable in the app

because i put money on the fact that someone else is already using that port for something and if they use my thing

then it will break everything

and for like

10 lines of code

it's not hard to do

[fossil dawn]

that's the thing... would it be possible to also discover the port that way? 🤔 Like have the PC program choose a random port that is free

[sick apex]

i dont think so

but for the ESP thing im making it into a library

and you'd have to init it anyway

[fossil dawn]

maybe if you use some kinda standard discovery protocol 🤔

[sick apex]

i mean i could make it respond to pings on port 80 to distribute the correct port

it'll be encrypted traffic anyways and it wont reply to any pings that it cant decrypt

[sick apex]

what do you think about the UI style for the desktop app?

[fossil dawn]

needs one of those generic corporate illustrations with the weird looking people and the error text "We are currently searching for devices" 😝

[sick apex]

hahaha

that's only there for my sanity

it will scan automatically whilst it's loading

and if it doesn't find anything imma put a massive

:/

[fossil dawn]

blue screen and :( 😝

[sick apex]

but i think it will be pretty cool when it works

the idea is

for each device it finds

it makes section

the device tells the app what it can do

so it will send some json

like

{
  "name": "ESP32 Light Controller",
  "Description": "Controls my amazing lights",
  "buttons": [
    {
      "title": "Light On",
      "func_id": 0
    },
    {
      "title": "Light Off",
      "func_id": 1
    }
  ]
}```

then when you press the light on button it will send a packet to that controller

with the ID

of what to run

once it has the ID

the board gets the packet

finds the function

and runs it

along with some that will be there

like a reset

which will just do the EN / RUN pin

pause which will just do a while loop that waits for the signal to unpause

stuff like that

imma add sliders to change brighnesses and stuff

colours

which you can implement into neopixel stuff

[fossil dawn]

oh nice

[sick apex]

yeah it's a neat lil thing

well it will be

just C++ doesn't like me

so it makes my threads break

[fossil dawn]

rewrite in rust

[sick apex]

i really cant be bothered lmfao

i teach unreal engine in C++

i do arduino

in C++

[fossil dawn]

port to rp2040

[sick apex]

im just so used to C++

[sick apex]

NO

THAT SDK IS THE WORK OF THE DEVIL

I HATE IT SO MUCH

[fossil dawn]

same, I've never used Rust 😆

[sick apex]

imma make the library for arduino

cause everything runs arduino

[fossil dawn]

including RP2040 😝

[sick apex]

yes

exactly

but the pico sdk

is satan spawn

if i had to port to that then picos would never have support for anything i make

i dont mind espidf

that's fine

but the pico sdk is just

icky

[fossil dawn]

why? I only used it a bit but idk didn't find it terrible

[sick apex]

i couldn't even get it to compile

with a blank project

[fossil dawn]

skill issue 😝

[sick apex]

it is

but one i dont have to deal with

cause platformio is just

the greatest

thing ever invented

im sorry but people who use cpp using namespace std; shouldn't be allowed to code

they should have the whole gcc taken away from them

[tardy badger]

Why?

[sick apex]

because it's disgusting

[tardy badger]

By that logic anyone who uses the namespace of any library they define should as well

[sick apex]

no, just omitting the writing of the namespace is icky

[tardy badger]

Why?

[sick apex]

because then you get errors

and its unclear

where things come from

[tardy badger]

You’re fine to have that opinion

[sick apex]

it's also terrible practice

and you'd get shot if you did that with a team of devs

[tardy badger]

Look, I work on a project at the company I work for that does namespace declarations and it’s just fine

[sick apex]

what

that's icky

that's gross

[tardy badger]

Again, you’re fine to have that opinion

[sick apex]

okay what if you wrote a function

called move

or you had a project

called atomic

then you've got

your constructor for example

called atomic

you've also got std::atomic

the compiler is smart but not smart enough to deal with that

or you're making a game and you call the movement function

move

[tardy badger]

First of all, why would you willingly name things after cstd functions

Second, many of these still require you to include it in the file

[sick apex]

i guarantee you don't know every single std function

you'd do it on accident

and if you're in a big file

and you include it

then you have to change all your

[tardy badger]

I guarantee you that a majority of the ones you expect have to be included

[sick apex]

cerr to std::cerr

it's just terrible practise

[tardy badger]

And the compiler will correct you

[sick apex]

sometimes

unless its unclear

and other compilers might play differently

and the same compiler might play differently depending on the rest of the code

[tardy badger]

But again, feel free to have that opinion. It’s just that, an opinion.

[sick apex]

it's 100% icky

[tardy badger]

In your opinion

[sick apex]

and the majority of others

anyways enough of that

i hate mutexes

and threading

but i love threading at the same time

amirite

[tardy badger]

Single threaded life

No dynamic allocations here

lol

[sick apex]

i have to multi thread because the thing im doing rn

needs a socket server

and it just stalls the GUI

otherwise

i need to write the protocol and i cba

[tardy badger]

Be a real professional and use a CLI

Jk

GUI are fun

[sick apex]

it's for controlling multiple mcus on a network

[tardy badger]

(I hate making them)

[sick apex]

i got this so far

but i cant seem to make the socket data go across

without stalling the gui

it's annoying

template <typename T>
class SafeQueue
{
public:
  void push(const T& value);
  T pop();

private:
  std::queue<T> queue_;
  std::mutex mutex_;
  std::condition_variable condition_;
};```

i made a thread safe queue

[tardy badger]

I’d still make a cli tool instead of a gui. Sure I could build a website, use JavaScript to be fun

[sick apex]

but that stalls the gui

when its waiting

[tardy badger]

Then use asynchronous polling

[sick apex]

i like to torture myself

as you can see

doing a gui

and sockets

and multi threading

in C++

[tardy badger]

If you really want to torture yourself, use Java

[sick apex]

atleast java has its own sockets library

i know java

i would've used it

[tardy badger]

A very useful socket library

[sick apex]

but intellij kept freezing

yes

[tardy badger]

And data pipelines

[sick apex]

you have to make your own in C++

its annoying

[tardy badger]

I mean, you could use boost

[sick apex]

talking to the windows api

[tardy badger]

Boost sockets

[sick apex]

yeah but i dont wanna use boost

cause i hate adding libraries

[tardy badger]

Boost is so nice though

[sick apex]

to c++ projects

it's a pain in the backside

they never work right

[tardy badger]

Boost is pretty straightforward to work with

[sick apex]

i cant even get vcpkg working anymore

it worked then it broke

well i already have the socket thing setup

[tardy badger]

The documentation is nice too

[sick apex]

it's working

{
  "name": "ESP32 Light Controller",
  "Description": "Controls my amazing lights",
  "buttons": [
    {
      "title": "Light On",
      "func_id": 0
    },
    {
      "title": "Light Off",
      "func_id": 1
    }
  ]
}```

i just need to write a protocol

to ask the mcu

for information about itself

it send that

or something like that

then it turns it into a struct

which goes into a vector

if it doesn't already exist

then i can load them into the GUI

hopefully without lag

i already gave myself a memory leak at 4mb / s

i fixed that though, i forgot to close the sockets when they were detached

like my braincells

[sick apex]

handshake complete

and im using UDP

[sick apex]

yes

waveshare has some quite small hdmi screen for pi

[ebon dew]

I don't specifically have an update for that but I did put in a PR that fixes the twitch api example due to breaking changes. It hasn't been approved yet.

Oh actually the PR was approved and didn't notice. https://github.com/adafruit/Adafruit_CircuitPython_Requests/blob/main/examples/requests_api_twitch.py

Oh it looks like those on Air sign learn guides are for Arduino. Sorry, I only updated it for Circuit Python.

@ebon dew thanks you for the post, that is even better as i have more rp2040 laying around then arduinos so it works out for me.

[ebon dew]

First they changed the name of hte API from kraken to helix so you'll want to change that.

and it ssems there's a broadcast type endpoint to see if a stream is live or not.

[radiant axle]

thanks again for the info dj

[urban arrow]

Over in circuitpython_dev, there's posts regarding espidf.memory error in CP9 when reading HTTPS sites. I posted my questions about this error here some time back. I've reverted my boards to CP8.2.8 that do reach https, and they work OK. Hoping there's some progress on this issue. No worries. Thanks!

[fair summit]

thanks - CP 9.0.0 is alpha. We appreciate the testing but it does have bugs

[pastel steppe]

I know you can buy DIY arcade sticks everywhere, but does anyone know if it’s possible to buy an extremely small set of buttons that could fit a Game boy shell? Or would that require me to find a PCB and a second pi to hook up to the pi that is running retropie?

[whole plover]

Have painted a living room and kitchen 2 coats. Living room is nice with 2 but the kitchen was pink so it needs 4 coats of what I have. Some organisation made and my desk setup (waiting for internet activation on the 4th which technically is now but I guess there's some config that starts on the 4th and go live could be any time on the 4th

Sleeping on a floor really is the worst at this age, I'm using pillows for my hips and ribs to save some of the pains lol

[whole plover]

You mean the button caps or the push buttons themselves or the full assembly? You could 3d print caps

[patent hemlock]

ew -- i would have try to go with one of those one-coat primers that supposedly prevents bleed-through, but if you were working with what was on-hand 🙁 ugh

[whole plover]

Yeh I've painted once before with brand paint and 2 coats was lovely, this was a "paint pack" given to me as part of the lease agreement. It's "contractors Matt white" which is totally fine it just needs extra coats. Also I should use it and every room will have a base to go on now if I decide to make a feature wall it won't take a minute after this

[pastel steppe]

I think I mean the button not the caps - I want to make a controller small enough to fit into my game boy housing but unsure if I’m getting in over my head

It just seems so straight forward and out of the box with a DIY arcade stick but unsure if it would be far more complicated if I wanted to just hook up some buttons to my raspberry pi - I’m new to this and I’m unsure what a good starting point would be for something like this

[pallid orbit]

I haven't done it myself but this looks relatively simple enough https://learn.adafruit.com/retro-gaming-with-raspberry-pi/adding-controls-hardware

instead of using the larger arcade buttons or joysticks you'd just use smaller ones. This also links into "PiGRRL" project breakdowns though those actually disassemble an existing SNES controller clone to use parts from.

Maybe that'll be helpful to start looking into, or someone else might have a better idea.

[pastel steppe]

Thank u, I will investigate o: !

hello all! i recently started in the world of adafruit feather... I adquired an esp34-s2 with tft... i used it to measure the height a water rocket can reach, and that was pretty awesome... all the kids at my kid's school were amazed!!

now... i would like to hear of possible other cool examples and utilities for this tiny board.... any idea?

[compact tangle]

Hi, there seems to be an error in this document: https://learn.adafruit.com/assets/111181

[dusty citrus]

Poe injectors have two ports: data in, and data out+power, is the data in port limited in inputs? I mean doesn't output anything? I am having struggles to detect that port while being connected

[whole plover]

You get all sorts of buttons from through hole to surface mount. You could just get some through hole buttons and they come in all sizes from 6mm up. Then you would wire it to whatever computer you are using. You can got example connect a button to ground and a pin on a raspberry pi GPIO then in code you listen for the press and broadcast it as a game controller which can be used to play games with

[umbral phoenix]

@dusty citrus data is bi-directional on both ports, one just also supplies power

is there a fediverse youtube?

I mostly just host videos for my own enjoyment, and the whole adblocker thing is driving me to consider self-hosting

[steady shale]

A little bit offtopic but I want a help with my home networking, I am using 2 router.
My primary router is connected with my pc and gateway is 192.168.0.1 and my 2nd router gateway is 192.168.0.2
Primary router has DHCP server enabled. The problem I want to talk about is, I am using pihole on my docker on my laptop. I want my 2nd router to provide adblocker type facilities. I changed its DNS on my 2nd router to my pihole address but it is not working. My pihole doesn't have any problem because if I add custom dns on each device separately, It works. I do not want to add this separately and I want it to work as soon as I connect to my 2nd router.

Can Anyone help me?

[hard estuary]

Yes, there is PeerTube: https://joinpeertube.org/

[ebon dew]

Give Router 2 a static IP of 192.168.0.2 but make a subnet with DHCP host set to 192.168.1.0/24. All devices connected to your pihole will be coming from a different subnet of 192.168.1.x and will default DNS/DHCP to that IP.

Look up some youtube videos on how to setup Pihole for subnets.

Induction or electric cooker?

Here they are phasing out gas, but probably another 15 to 20 years. I love cooking with gas but is it the time to swap to electric?

[whole plover]

You can use proto board and cut it with a dremel for your buttons and then wire the buttons with solder as through hole. That's the quickest way without investing in a custom PCB design, but I don't know what case you have or the condition of it. I did a handheld which was a 3d printed case and had mounts for proto board with my buttons, then I 3d printed some caps for it all

[whole plover]

I had it plugged into a wall socket that wasn't connected to anything. I wish they would remove these things..

Painted kitchen 4 coats. It's not great, it was such an awkward room to paint. I really should take the wall cupboards off and paint it less awkward but I'd need some helping hands for that and don't have anyone around at the moment. It's fine. I'll do some vinyls on the cupboard panels and make it more cool with accessories

@patent hemlock

[rapid geode]

induction is great if you have the right pots. radiant is terrible. no control.

[whole plover]

Great advice. Cheers 🍻

Induction is about a third more expensive but feels like a good investment

[rapid geode]

i have a bosch one i ordered from spain for $190 euros.

(they are $2000 here)

[whole plover]

Electric for me would come in about £400 and induction starts about £600

Its a free standing unit and comes with oven and grill, have seen the stand alone induction hobs and considered that but would prefer to have the range

why cant I find AdafruitSAMD in the arduino library to add a featherwing to my boards

[ancient rivet]

it's not a library. it's a board support package.

don't know what SAMD board you are using, but it'd be the same general process as shown here:

also - don't confuse Arduino SAMD with Adafruit SAMD. you'll want to install both.

[lilac sapphire]

thanks took a couple of tries but got I think

[hasty niche]

You can make a NYC slice at home by adding salt and baking powder to the water

It's the water toxicity that makes the pizza dough cook differently. The elevated lead levels probably help with the taste

Boston pizza has even softer water

Gotta make the PH 0

You could also try cooking the pizza with distilled water instead

$1 a gallon at Walmart

[fickle aurora]

Nah, the water thing is a myth. It doesn’t matter much beyond the hydration level in the dough

[hasty niche]

Try it then. Distilled water is cheap.

It makes a difference.

[fickle aurora]

https://www.seriouseats.com/does-nyc-water-make-a-difference-in-pizza-quality

I have done distilled water a few times. Eventually just went back to filtered

Modernist Pizza also states water doesn’t matter much, and they spent 200,000 hours studying pizza

What a dream job

[hasty niche]

My tap water actually makes the dough change texture. It's pretty dirty

The landlord actually had to install a water softener because it was clogging our pipes.

[fickle aurora]

Part pizza part tiny rocks and minerals 🤣

[hasty niche]

The local government tripled the chlorine content to illegal levels when covid started causing issues too

It's back to normal now though

[rapid geode]

i use tap water, its fine here. ive lived in some other places with very hard water, almost slimey.

chlorine people dont quite get. by the time you use the water, there is no chlorine in it. it has all off gassed

so no matter what level is in it, it does not impact your food (short of having less bacteria)

[glad ruin]

CHLORINE WILL KILL THE COVID
Well yes, but it kills living cells in general, so...
SHUSH, WE SHALL PASS POLICIES TO MAKE PEOPLE FEEL SAFE.
Also, it is transmitted through microdroplets ejected into the air, not through food and drink.
WE SHALL RELEASE CHLORINE GAS INTO THE AIR TO KILL THE COVID!

Lego itself it's a rip-off
Who originally patented legos as an invention died from suicide if I don't wrongly remember

[pallid orbit]

LEGO was inspired by Kiddicraft self-locking blocks, made by Hilary Page, and it was a mutually accepted design copy as he wasn't having success with his kiddicraft blocks, and they didn't violate his patent - plus they contacted him for permission to avoid conflicts.

LEGO acquired the remaining kiddicraft rights from his kids after his death a few decades later.

They even have info about it on their site https://www.lego.com/en-us/history/articles/c-automatic-binding-bricks

Have a question…. How can the the QT PY pin out online be sooooooo far off reality?

If I go by the official pin out nothing works! Have to randomly go through pins to find what works.

Settings set as 26,27 and 32 run my lights…. Pin out online says these are 2, 16 and 6,….

I’m trying to add a button and found I can not use the 4 pin connector like I used too. Was simple before.. what happened?

[fossil dawn]

Honestly I have no idea what you mean

[agile dune]

How do I find the real pin out for a QT PY?

[fossil dawn]

Make sure to use the pinout for the exact correct QTPY

And a program like wled... I don't know what kinda pin names it uses but it might be different that the Arduino/Circuitpython pin names

[agile dune]

Last time I built some this small I used the same HW and used the little 4 pin stem QT 4 pin connector and grabbed 3v, gnd and signal, now the pin out online says these can not be used for analog input.

Sda and scl. Inputs.

September 13th I had an issue and it was solved in this chat. If that helps.

Did the QT PY boars change?

[pallid orbit]

There are like half a dozen different QT PYs with different GPIO pinouts. Which one do you have?

[agile dune]

Esp32 pico.

[pallid orbit]

https://learn.adafruit.com/adafruit-qt-py-esp32-pico/pinouts

[scenic osprey]

that's... 25 times more expensive...

[scenic osprey]

I don't need ir imaging

[agile dune]

It’s the only one that will run wled right?

[pallid orbit]

I'm not familiar with WLED sorry

but that's the pinout chart for that specific QT PY model

[agile dune]

Wow. Pinoits are way different!!! Trying now. Thank you.

[pallid orbit]

Np. There's QT PY: ESP32 Pico, ESP32-C3, ESP32-S2, ESP32-S3, RP2040 that I know of, each is different

hi everyone, i have been looking up and down for the 3D design files that were created from this video : https://www.youtube.com/watch?v=FA7a-n7o_Mg&ab_channel=AdafruitIndustries
I have looked in the github link in the video description, I've tried contacting the guy in the video on instagram, email, etc. to no avail. Can anyone let me know where I can find them? Or where else to look?

[late fulcrum]

Yeah - you said "better" but didn't define what "better" meant...

[late fulcrum]

I don't know where to find it, but it might be quicker to re-create it than to dig it up.

[dusk path]

unfortunately i dont know anything about fusion 360

i was hoping i could find the files and send them to a guy that has a 3d printer i know...but i cant find them

[rapid geode]

seems like a good time to learn 🙂

[late fulcrum]

It wouldn't be hard to do in OpenSCAD (that's how I would have done it)

[dusk path]

how much would you charge to do it 🙂

[late fulcrum]

That depends on how much of a hurry you're in

[rapid geode]

i would charge 12 pies.

[tranquil swallow]

I'd charge the approximate cost for a delivery meal + delivery fee + tip + tax on the meal, tip and delivery fee.

But that does look trivial to make in fusion 360

[dusty citrus]

Besides cutting a flat face into this screw via an hammer or power tool what could I do? Boss it's a consumer maniac so I can't be heard
Glue cannot be used; tape/elastic bands were unusefull

[late fulcrum]

You can also carve an opening for a hex, Torx, triangle, etc. driver. I've done this a few times for smaller screws when restoring antique sewing machines and not wanting to damage anything next to the screw.

Depending on the drivers you have available, you can also drill a pair of holes and open it with a driver for "twin hole", "snake eye", or "pig nose" screws.

This takes less skill and offers lots of torque, if you have two hole drivers on hand

[dusty citrus]

What do you mean?

[late fulcrum]

This might make it clearer https://www.insight-security.com/twin-hole-security-screws

[dusty citrus]

I see but I can't really drill the screw?
What if I cutted the screw sides with some pliers and then use some flat head to try to unscrew it?

[late fulcrum]

If you can get at the edges of the screw, you might be able to grab it with pliers or Vice Grips and turn it. There are pliers made for just this job: https://www.adafruit.com/product/396

[dusk path]

ok suppose I wanted it next week?

[thick wind]

Cutting the sides is a valid option similar to the flat face, but the ends of a small screw like that might not be easy to pry up, assuming there’s some countersink to that. Drill/dremel would be my go-to, but given your constraints, that might be off your table.

[wide mural]

Guys i really need some help with my project. I’m implementing duplex communication via mqtt. But .onMessage() function is not getting called at all.

https://github.com/moizghumann/IoT_Temperature_Control/blob/main/sketch_dec3c.ino

[whole plover]

If you can cut the screw what's stopping you using needle grips and just turning the screw? @dusty citrus

Just bend it up a little at the edges if you can't get a good grab

[rapid geode]

just drill the thing out like a normal person?

why you gotta try and make everythign complicated? 😛

[fair summit]

not sure what this means:

Boss it's a consumer maniac

[dusty citrus]

In the end I managed to put it without unscrewing the screw, by moving around/bending that sheet metal like thing

[dusty citrus]

How can I say... When someone handles everything like a really fragile crystalline substance, while there's no need

[vestal plume]

Does anyone know good book that is about microcontrollers like what it is, how it works, types of microcontrollers and history?

[dusty citrus]

Eh I can't really recommend any in particular they're all the same in the end.
You have lots of documentation online, including adafruit's docs, allaboutelectronics, or specific to the device distrubutors/manufacturers and so on

[fair summit]

ok thx I need this as material for bachelor thesis so thats why I asked for book, since I need trustworthy source

[tardy badger]

Bachelor thesis, interesting

Is that like senior design ?

[vestal plume]

Not sure what do you mean, but it is my final work to get a degree

[tardy badger]

I had to take a two part course where I and a team had to devise and execute an engineering project and deliver a massive report, presentation, and demonstration of the work done.

It was called a Senior Design Project because it’s done by engineering students in their final/senior year

[vestal plume]

that sounds good and useful unlike what I am doing.

[tardy badger]

I did undergrad research too which was cool

Got to be an NSF fellow one summer

[fossil dawn]

I found it surprisingly interesting and understandable to just read the datasheet of the microcontroller I'm using

[vestal plume]

I wish our education system adapted to software engineer since their type of learning is so much different from others

[fossil dawn]

in one of my current classes the professor just takes a surprisingly large amount of content straight out of the atmega328p datasheet 😆

[tardy badger]

My bachelors degree is in computer engineering

We used a lot of TI microcontrollers

MSP430, MSP432 mostly

Also Xilinx Spartan 6 FPGA

Maybe a Spartan 7, I can’t remember what’s on the Basys3 boards from diligent

[vestal plume]

meanwhile our school equipment best I can do is theoretical powerpoint presentation and rest is up to you >D

[tardy badger]

Oh Artix-7

[tardy badger]

US based school?

Or overseas?

[vestal plume]

overseas

[tardy badger]

Oh dang, yeah that can complicate things

[vestal plume]

I mean it is my own fault so yeah but I am hoping to get into better school for magister degree

[tardy badger]

Depending on where you are, you could get an education that throws you deep into new technologies like is happening at many Indian universities, or just getting enough knowledge to get by with needing a lot of scrappiness to learn it in your own

[wide mural]

Oh okay. My bad

[tardy badger]

All good

To be fair though, quality at even US universities is really starting to suck.

In many cases, a lot of electrical and hardware focused engineering degrees are severely underfunded and ill equipped to teach modern engineering

[vestal plume]

I mean in the end it is really up to you but it wouldnt hurt to see bit more enthusiasm from professors.

[tardy badger]

Absolutely

But to be fair, as they’ve seen people just cheat and be dishonest about their efforts to learn materials, it’s easy to see why many have given up

[vestal plume]

Same our education system is underfunded a lot, but it depands where you go we still we have a one relly good public uni but it is pain to be there, you have no sleep since if you snooze you loose

meaning that you need to be learning a lot in order to not be expeled

[tardy badger]

I had one professor who a few students threatened him to the point where he no longer would allow you to show your work on tests and quizzes. Final answer all or nothing

It was pretty messed up

[vestal plume]

daaam yeah also same here students are getting lot more toxic

Unpopular opinion but their parents didnt beat them enough 😄 meaning that their parent did not teach them good manners

[tardy badger]

But I get what you’re saying, they were not raised to respect people, especially those giving their time and knowledge to educate them

It was honestly a bit sad because most of the students respected the professor even if they were harder on students than other professors work

[vestal plume]

I would never think about disrespecting my professor even If I think he is lazy person with no skills to learn others

[hasty quarry]

Looked into the Arduino EEPROM library, and out of curiosity looked into its source code

They have a super super clean EEPtr and EERef set of utility structs

Most example code snippets I saw keep track of the address themselves, and do read() and write() explicitly. Why not use an EEPtr which abstracts this away? Super pretty code, I love its implementation

*(eeAddress++) = …the byte…;
This clearly writes to the current byte, and shifts to the next address

Do the docs assume people don’t know much C++?

Because if that’s the case, I understand. EEPtr just seems too good to not mention right off the bat

[exotic yarrow]

Are solid models available for adafruit components? Looking specifically for 2324. Only finding board diagrams but no solid models

[whole plover]

I had to remove a wall plug and screw yesterday using my wire snips. It wasn't pretty and then I discovered I own a crow bar which has a pincer on the other end

[hard estuary]

If there is a CAD part for it, it would be here, but I don't see it for 2324: https://github.com/adafruit/Adafruit_CAD_Parts

[exotic yarrow]

Rad thank you!

[molten raft]

Is there any sort of way to contact Adafruit to request a custom version of one of their products

I'm running into an issue that could be practically entirely solved if this board just had USB-C instead of Micro USB https://www.adafruit.com/product/2341

[tardy badger]

What’s your issue?

[molten raft]

Long story short, I'm making a replica of Han Solo's blaster, and want to use that board I linked to add sounds. I'd like it to have a single USB C slot that allows accessing the files on the sound board and charging of the internal battery

[tardy badger]

Can you use the USB C panel mount cables they sell?

https://www.adafruit.com/product/4259 or something like this

[molten raft]

nowhere near enough room in the blaster sadly

Just that adapter would exceed the width I have available, and take up probably 60% or more of the internal volume even if it could be slimmed down

[tardy badger]

Gotcha, yeah that’s a tricky problem

They sell the raw chip so you could probably take Adafruit’s design and make it yourself with the usb c connector and LiPo charging on one board that fits better

[molten raft]

Alright. That may be my best bet, although I suspect at that point, I may be better off investing in a BlasterCore board

[tardy badger]

Perhaps, but not nearly as satisfying as designing your own board (in my own opinion that is )

🙂

[molten raft]

I don't have the skills to do that sadly

[tardy badger]

Only way to get them is to start somewhere. This is a great project that you can crib heavily from Adafruit on

They’ve done the ground work for you on the codec board, the battery charger, and whatnot

[molten raft]

Yeah

[tardy badger]

Plus we have helpers here like myself able to help you along the way in the #help-with-hw-design channel

[molten raft]

I mean literally all I need is that board to just have a USB C plug on it

Which feels like it should be something they make already honestly

[tardy badger]

It is likely in the works

But it can take some time for new products to hit the store

[molten raft]

Yeah

[tardy badger]

You’d have a faster turnaround doing it yourself plus the experience gained is so valuable

Either way, always here to help if you take the jump

[molten raft]

Yeah

Do you have any recommended services for custom PCB production?

Oh no I'd probably need to solder the IC to the PCB if I were to go that route, wouldn't I

As proud as I am of my soldering skills, I think trying to accurately solder all the pieces to this would be impossible for me

[umbral phoenix]

@molten raft this combo probably still too big?

unfortunately USB-C pin layout is slightly off from a Micro connector, but could maybe work with some tweaking:

there are breakouts too, but I didn't see one for USB-C jack

[tardy badger]

with a little bit of practice, it isn't too hard to do SMT soldering. you can get a solder paste stencil from JLCPCB or PCBWay, you can even have them assemble a majority of the board for you, leaving just the codec chip to attach

JLCPCB has the advantage of owning and being connected to parts site LCSC

it's possible they have the codec chip in stock

oh nice, they do

so yeah, you could design the PCB and have JLCPCB assemble it for you without having to solder anything too difficult

[rapid geode]

SMT is super easy. i just send it to my friend and make them do it

runs

[orchid saffron]

old apple computer and power book

[pastel steppe]

We have movement

[acoustic pawn]

If you have a stencil cutter and some 4mil Mylar film, you can make some pretty good solder stencils

Good enough for most prototyping work

[fickle aurora]

What’s the story behind the name of the qualia line?

[tardy badger]

Ever put in a back order for something and then forget to cancel it? Happened to me this morning

[late fulcrum]

It depends somewhat on where you are in the world, but DigiKey offers next day shipping to a lot of places.

[rapid geode]

in fairness, usually you back order thing you WANT 😛

[tardy badger]

Well I back order CM4 from mouser but then a few months back I got some from digikey and kind of spaced canceling the back order lol

[pallid orbit]

CM4s can be tough to find, I don't blame you there

[dusk path]

i would like to purchase a neoring 16 or 24, what wire would i need to purchase for it to plug into a 3pin port?

actually, does the neoring require 4 wires?

[patent hemlock]

that's a little vague: there are lots of "3 pin ports" and lots of WS281x rings out there

[dusk path]

well, im trying to go from a neopixel ring to a pico, and the pico im using has various plug inputs...so i just need to know what kind of wire i need to buy to solder to the neoring and has the right male plug on the other end

im new to this btw

this is the box im dealing with

it has various inputs (and various input types) that are mapped into the pico

[patent hemlock]

the manufacturer of said box should have details on all of that (i don't even know what that thing is 😆 )

[rapid geode]

Name the woods. haha

[fossil dawn]

I've never seen that PCB below the pico. Best to check its documentation to see what plugs they are. And make sure that the pinout (which pin of the plug is what) is also correct. Just because something physically fits, doesn't mean that it is electrically correct

https://www.adafruit.com/product/1586 Those neopixel Rings that adafruit sells have no connectors. You just solder wires to them. And you can obviously solder wires with whatever connector you want to it

[ancient rivet]

neopixels use 3 pins: power, gnd, data

the connectors on the PCB in the box are a mix of 2 pin, 3 pin, and other (one QWICC)

so, yah, it's unknown exactly what those connectors are in terms of pin usage going back to the Pico itself

also unknown is what the actual connector is. only the QWIIC one appears to be JST (SH in this case)

you can drive neopixel directly from the Pico, it's just a matter of what pins those connectors are bringing out

another option, if you wanted to use that QWIIC connector is this:
https://www.adafruit.com/product/5766

[fossil dawn]

And what are those components and what do they do on that blue PCB? 🤔

[atomic kettle]

hello everyone :D. Long time adafruit customer but first time discord user. I'm working on a build right now but having an issue with the OV5640 camera module, is there a general place I can discuss my issue to see if anyone has any insight. I have done extensive googling and attempting to solve 😄

[dusk path]

cater, thank you for the info...im really just tryingto get to a point where i can "plug in" the neopixel and get moving. im stuck right now because i dont have a soldering iron and i didnt know how to get it functioning at all because i dont know what plug to use. i have one of those neopixel strips with 24 lights in the image on that link you posted, but the plug that comes out of it is about 3x too big to fit on this board.

[fossil dawn]

We have no idea what the plugs on that blue board are. We don't even know what that board even is. You have to check the documentation for that board.

[dusk path]

yea ive asked the developer of it for that

[fossil dawn]

I think the cleanest solution is probably to solder new wires with the correct plug to the neopixel strip. If you're really lucky you might find adapters. Or you could cut the wires and then use some kind of screw terminals or something to connect the wires (with the neopixel rings on them) to the wires with the plugs for the blue board

[hard estuary]

Welcome! That's what the Discord is for. How are you programming it? There are #help-with channels for Arduino, CircuitPython and #help-with-projects is more of a catch-all as well.

[dusk path]

im using the VCNL4040 in conjunction with a 4 way MUX board, there would be 4 VCNL4040's and each one would need a NeoPixel 24 Ring. ideally i would love to just plug the ring right into the VCNL4040 since they will be mounted right next to each other. but i dont know if thats possible

the VCNL4040's have an input and output...leading me to believe it might be possible to daisy chain them, but im not sure

but at this point im so new to it, im not sure what components woudl be required to achieve what im doing. i am trying to illuminate an LED ring when motion is detected by up to 6 motion sensors (so 6 LEDs)

each LED ring is paired to a single motion sensor. so when motion sensor 3 is triggered, LED 3 is illuminated

[atomic kettle]

awesome! posted 😄

[fossil dawn]

yeah, I think you definitely need a microcontroller. You can't plug neopixels straight into a sensor

[fossil dawn]

They're I2C, right? If yes, then you can put them on the same I2S bus as long as you can give each sensor a different address (or use I2C multiplexer/switch/forgotTheName)

But I would start with one thing at a time

Like, first just get the sensor working and Serial.print its value.
Then just get the Neopixels working and have them display static "information".
Then combine one sensor + one neopixel ring.
Then add multiple

[dusk path]

thats kinda what im doing, i have the mux working with 3 sensors and can detect them all via circuit python and print out their values

now im just trying to get the neopixel integrated which is qhere im stuck

[ancient rivet]

@dusk path is there any kind of product page you can link for that board?

[dusk path]

ive asked for a diagram

[patent hemlock]

as suggested, there's the I2C neopixel driver board, since you've already got the mux -- then all you need to do is figure out how to get 5v to each of those driver boards

[edgy apex]

I've been working on a design for my friend, he sent me this video
https://youtu.be/dZm_JRxJiYA?si=9s-NnSClpPuAQaU5&t=140
he said it would be helpful to him to have something like that for getting in and our of his car so I used openscad to design one, I had to get a little creative to get it to fit on my printer. I know the pvc will fit perfect because i did a test print to make sure. I have yet to print the whole thing which I'm gonna try to do soon afaik it should be good, if all goes well i may end up making more.
https://www.thingiverse.com/thing:6362373

[dusk path]

the i2c cable doesnt supply power?

[ancient rivet]

yes. but 3.3V. and generally not meant for something as power hungry as neopixels.

there would be 4 VCNL4040's and each one would need a NeoPixel 24 Ring

so 96 neopixels total

info on neopixel powering here:
https://learn.adafruit.com/adafruit-neopixel-uberguide/powering-neopixels

[patent hemlock]

no, it requires an external 5v input, which is then properly routed to the Vin on the strip - https://www.adafruit.com/product/5766

[dusk path]

but not all at the same time. it would only ever light up 1 ring for a few seconds

[ancient rivet]

you might be able to get away with it then

but neopixels are also 5v things. so getting them working with 3.3V power and logic can be hit or miss.

[dusk path]

at this point id be ok if it just operated. id like to get started coding but cant without something thats physically working to test with

[ancient rivet]

without information on that other board, it's not clear how to make the connections

the two QWIIC connectors should be known pinouts though

they seem to be working with your other I2C breakouts, so seems like they are

[dusk path]

yes they work...i have 3 sensors connected to the MUX and i can detect them all in code

the sensors have a QWIIC in/out, could i hypothetically go MUX->Sensor->Driver board->NEOPIXEL over a QWIIC cable? or would i still need extra power supplied to it?

[ancient rivet]

you can't mix i2c with neopixel

[pallid orbit]

neopixel has its own unique timing right?

[ancient rivet]

yes

[dusk path]

so id have to go board->QWIIC->Driver Board->NeoPixel?

[ancient rivet]

yes, if you wanted things to be all on the same I2C bus

do you have the neopixel rings already?

[dusk path]

i have 1 on hand, yes

[ancient rivet]

any wires attached to it yet?

[dusk path]

no

thats one of my main questions is which wire do i need to buy to get it connected to the board where i can communicate with it...hopefully without too much soldering (or none if possible, for now anyways)

[ancient rivet]

soldering will be needed

the rings only have bare solder pads for connecting

[dusk path]

ok...i can manage that as long as i know that its the right step forward

[ancient rivet]

exactly what wires you solder and how is up to you and would generally depend on the your final hardware arrangement

do you have a STEMMA QT cable like this?
https://www.adafruit.com/product/4397

[dusk path]

no, but i can order one

[ancient rivet]

or this?
https://www.adafruit.com/product/4209

if you don't have those cables, i'd say wait to you'll get more info on what those other connectors on the board are

[dusk path]

what would i do if i had that second one?

[ancient rivet]

you could solder some wires to the ring and then use that STEMMA QT cable to bridge the connection using a breadboard

and use the other QWIIC port

but that's like a total hack just to get something blinking today

and only being suggest because those are the only ports on that board that currently have known pinouts

[fossil dawn]

I'm curious. What even is that blue pcb? Like what's it's point? What do those components on it do?
You could always also just wire stuff to the Pi Pico directly

[glad ruin]

Point to point construction is time consuming.

[fossil dawn]

It might even have enough pins so you don't have to solder a lot/don't need a breadboard to split power and ground

[glad ruin]

And PCBs are cheap.

[fossil dawn]

yes, but if you don't know what the connector on the PCB are and you don't have the wires for it then just wiring directly to the Pico might be faster 😄

But yeah, I think I should start designing my own PCBs like that. Could definitely make projects way neater

[cloud pilot]

anybody know where i can purchase ONLY the smaller cables in bulk? i need a ton of them but i dont need the long ones. hoping to buy like a 100pc of the 5,7,10mms each

On average how long does it take to get items from adafruit off their website? I’m in California.

[glad ruin]

[patent hemlock]

USPS usually takes 1 week to Seattle

[half plank]

Does anyone know of a good 20 channel adc and 20 channel dac if that is even a thing?

[glad ruin]

I'll need to know more about your requirements... Resolution? Sample rate? What are you measuring? Etc.

[lusty fossil]

4 to 7 days for me

[half plank]

All I really know is that I have 20 line of analog that need to be encoded to two line transferred over a cable to a dac then have 20 line of output analog

[glad ruin]

There are multiple approaches that can be taken, but the sample rate and resolution requirements will determine which is best. Also, you need to be aware of the fact that ADC input stages can be quite noisy at times, so if you are trying to sample from some sort of sensor, there will likely need to be some additional amplification before converting the signal(s). As far as the two lines are concerned, has a particular protocol been chosen yet?

Kinda surprised that there isn't a model like this (component lead bender) but for making standard length jumpers. Should be trivial to design one. That, and one of these wire strippers and you're good to go.

[ebon dew]

You'll want a punchdown tool and crimp tool too. Makes things a lot easier.

as simplistic as those little jacket strippers are they really do work better than metal tools twice as expensive... and they're kinda disposable.

Hi does anyone know a good literature about single board computes (what are they, how do they work, different types, what are their uses and history)?

[rapid geode]

which stock feather board can keep time as a clock? do you even need an rtc for that?

[umbral phoenix]

depends on the accuracy you want, different MCUs have different drift, but you do need a way to set the time initially (and periodically dependent on drift and time source)

readily-available sources: battery-backed rtc (e.g., adalogger featherwing), wifi (e.g., various S2 or S3 feather boards), gps (featherwing or external module), manual, etc.

[rapid geode]

it just needs to tell time as good as a regular quartz clock

its not doing anything special. but the mechanism for the "hands" isnt suited to the standard clock guts

[umbral phoenix]

assuming the device can get network access, the easiest thing (to me) is a wifi feather, you can get NTP time (or via HTTP) as often as you need

without network access, probably a dedicated RTC that you can manually adjust maybe... annually?

if you rely on most MCUs without an external time source, you're at the mercy of their drift (and loss of power, etc.) and may get frustrated how often it needs manual adjustment of the time

TROGDOOORRRR!

[dusk path]

is there an api with circuit python that allows you to query for devices plugged in via i2c and uniquely identify each device? like if i had 8 off the same sensors does each one have its own id?

[umbral phoenix]

@dusk path there is an I2C scan that will show all the addresses on the bus, but if you have eight identical sensors, they need eight unique addresses, and that must be accommodated on the board with jumpers or something

you can use an i2c multiplexer if you can’t change the addresses to be unique

[ebon dew]

I love Adafruit's PCA multiplexers that have stemma plugs. Makes hooking up multiple stemma devices with the same address super easy.

hi

In which channel can I find assistance for issues with flashing the Adafruit ESP32-S3 Feather?

[ancient rivet]

depends on what you're flashing. if it's arduino related, there's #help-with-arduino . if it's circuitpython related, there's #help-with-circuitpython . if it's more generic, then maybe #help-with-projects

[limber dome]

I'm going to need to make a charging bay for these does anybody suggest a board that has more than one charging port? Could be sweet to make one that had like six

[fossil dawn]

Please double and triple check the polarity! Those adafruit LiPos are normal LiPos and NOT "HV", so make sure that the charger is set to normal LiPo mode. Also make sure that the charging rate isn't too fast!
I think you could use something intended for FPV drone batteries. Tiny FPV drones also use 1S LiPos with PH plug and since they last for about 2 minutes, chargers for many LiPos at a time exist.
https://www.racedayquads.com/products/vifly-whoopstor-1s-battery-charger
https://www.racedayquads.com/collections/battery-chargers-accessories/products/betafpv-6-port-1s-charger-for-bt2-0-ph2-0-with-or-without-ac-adapter (i think this one has a fixed charging rate of 1A, might be too fast for your lipos!)
(Maybe those two links are kinda overkill for your purpose 😆)

[limber dome]

Yeah I think the little boards only supply 100 milliamps to these batteries. It seems like it takes about as long to charge it as it lasts

I've changed the transmit times on my dog tracker so that it didn't do it as often. That helped quite a bit for that one. But on my mobile receiver I just leave it plugged in to my USB all the time. But I drive my less than half the time so it shuts off at night and that never gets fully charged because I don't drive for 12 hours

Obviously I could just put a switch but yeah I kind of just want to be able to stick it on my dash and forget about it

I felt bad for the battery so I've just been taking it inside and charging it on some random board and switching it with another one

I'll probably just stick a solar panel on it and see how long it lasts

Eventually, a Raspberry Pi will replace the PC, but before purchasing the Raspberry Pi, I want to make sure I can get everything working. Currently, I'm stuck at the flashing stage and have difficulty understanding the error description.

having aspect ratios that are too far from the ideal can sometimes lead to surcharges, from what i recall, because it makes it harder to pack the trucks/freight containers efficiently

[tardy badger]

Buy a roll of stickers and slap them in your boxes

Pretty easy in between plus can function as a seal

[cloud pilot]

i need roughly 16x11x7

thats for my Ray Gun, i have other massive weapons that are like 4 feet in length

[tardy badger]

That is large

[cloud pilot]

they ray gun? or the 4 ft one lol

or both

[tardy badger]

Yes

Looks like $5.50 is the average price for the 16x11x7 box

If you order 25

[cloud pilot]

yeah :/

[weary surge]

Hey fellas, not sure if this is the right place to ask, my car battery charger clamps are messed up and need to be replaced. I figured I might aswell replace the cables with built in connector to make the cable removable. Would anyone have any connector suggestions? I was thinking XT60 might be good enough? the car charger is rated at 12 amps charge, I believe it would around 14v

[rapid geode]

oh man. its horrible. i got quotes of 5-$25 per cardboard box to pack something worth $30

i made my own packaging in the end

if im gonna pay, i may as well pay myself 😛

[late fulcrum]

That should work. My usual go-to is Anderson Powerpole connectors, available in various amperages (the 30A ones are popular for ham radio use)

[glad ruin]

Powerpole is nice. I do wish there were smaller/lower current variants, as well as some kind of PCB mounting solution.

[rapid geode]

done, yay. just needs a box... sigh

[umbral phoenix]

...and some keys

[rapid geode]

pretty sure they have matching keys to go with it

haha

(for my friends brother, he has an S3)

i wanted to do the black part as a colour match with touch up paint, but i couldnt find any that i could get fast

[umbral phoenix]

next up, a light-up version that sends the bat signal like the puddle lights 😉

[rapid geode]

ha

[shell canyon]

Did anyone controlled a Quelima SQ13 camera with a microcontroller? (Using signals from mcu instead of opening it and starting video recording by clicking its button)

I've had good luck ordering custom sized boxes from ecoenclose: https://www.ecoenclose.com/shop/custom-shipping-boxes/ They do printing from 100+ boxes. Not sure of the cost.

you can ask about it during ask and engineer tonight

[rapid geode]

once you get to 1000 or so i find the prices colapse rapidly. Below that the biggest cost is the set up work for the cutting and printing. One of the alternatives ive seen being used is a sleeve. you get a plain box, and a printed thin card sleeve to wrap the box. but this is usally for smaller boxes.

[fair summit]

some info here about suppliers, but not specifically about printing: https://blog.adafruit.com/2014/04/14/alternatives-to-uline-shipping-supplies-shipping-boxes-packing-materials-and-mailing-supplies-makerbusiness-manufacturing-uline/ (has been updated since original posting)

Stickers are cheap too.

[nocturne agate]

i just deepfried a potentiometer which caused the smoke detector to go off

it was a canon event

[nocturne agate]

accidentally connected 5v to output

[late fulcrum]

I've done that more than once. Ah, the smell of burning Ohmite.

[nocturne agate]

yep, was my first time tho

[pallid orbit]

on the plus side you know your smoke detector works 😆

[whole jacinth]

oh yeah, the old "hook the wiper to one end of the pot to get a nonlinear output voltage" while wired between power and ground, then turning it to the wrong end…

[nocturne agate]

kind of, i was just getting some wires ready and plugged the wrong one into the central port

confused the 5v with the analog output…

[nocturne agate]

i also now know that its really annoying to turn off and also really loud

[urban arrow]

Tell you guys what... after hundreds of times typing = and == in CP, I still do it wrong and wonder where my mistake was... 🙁 I DO know the difference...

[nocturne agate]

cp?

[urban arrow]

circuitpython

[nocturne agate]

ah

good

[nocturne agate]

mate i sometimes copy-paste code and then forget to change up a number, like 1 -> 2

and then debug for 2 hours

[patent hemlock]

that happens in most of the programming languages i use (i also invert booleans the wrong way a lot)

[pallid orbit]

worst bug I had to debug from one of my projects was mixing up x and z in some collision raycasting code for procedurally generated levels, where parts of the layout were 'correct' and then others it was passing through, and had a visualizer etc for everything, had no idea... then eventually noticed I had used x twice

[nocturne agate]

i was writing a config file parser and accidentally used 1 twice instead of 1 and 2

was debugging for 1.5 hours

[pallid orbit]

this took more than 2 hours to debug

[urban arrow]

AND I love forgetting to add the semi-colon end-of-line when I have to switch to Arduino

[patent hemlock]

EOL markers really screwed me up in the early days (Pascal sux, folks)

[patent hemlock]

i know this chat isn't "real time" (so to speak), but is anyone experiencing outages for microsoft-owned properties? i can't get bing, linkedin, or github to respond (or even duckduckgo, which i believe is on azure)

[rapid geode]

all fine here. maybe MS just banned

[pallid orbit]

github and some other azure services working fine for me

[patent hemlock]

interesting -- traceroute sends me to a cogent server (all 4) and then just bounces around, but if i check microsoft.com it goes through the same server but exits
gah
heh, the internet has re-routed and it's working 😏

[tardy badger]

Me: stares at 5 CM4 I can’t use because I don’t have any carriers

[rapid geode]

i seeeee

maybe you should send me one.

did you think about that? no, didnt think so

haha

i have to rearrange all my guitar cad files today. that will be entertainging

[tardy badger]

Lol

[weary fiber]

anyone know what TD[1] and TD[2] mean here? (pinout for the adafruit feather NRF52)

The key says it's their "pin function" but I can't find anything more than that on google

I thought it might be like... interrupts? but this board accepts interrupts on every pin

nvm, did some research: it's a shortening of TraceData. The NRF52, on top of having SWD, has the ability to view "traces" from the cortex M4's "Instrumentation trace macrocell (ITM)" & "Embedded trace macrocell (ETM)" via a 4 pin protocol on the TraceData pins

i need this in my house

[tardy badger]

That would save me a lot of time

[rapid geode]

i like that it is all recognisable gear. delta robots and suction cups

[limber dome]

Got a nice little vector scope. Now I can tune my handmade antennas the housing changes it quite a bit so after turning it with the housing was able to peg it right at 900 MHz and the range of the radio and it has a nice reception on higher bands making it perfect for tracking airplanes also.

[whole plover]

this is the type of thing i'm looking from abs prints

[tranquil swallow]

have you seen the bambu a1, it's beautiful for only $640 cdn

[tardy badger]

I tell ya, I was not expecting to laugh so hard this early in the morning

[rapid geode]

ah good to see their solution to the breaking windows

[fair summit]

You can, it is just not as convenient as stacking Feathers.
