Lead-free?

[tardy badger]

Always

I’m developing products for sale as a company so I need to avoid leaded where possible

[raw jasper]

650F should be enough, though, even for lead-free

[tardy badger]

I usually use low temp

[raw jasper]

(I don't --can't-- solder, but I hate lead)

[tardy badger]

I think the ground plane was just wicking the heat away too much

[raw jasper]

ooh yeah, makes sense

[tardy badger]

The pads that lifted off were ground pads

[raw jasper]

Ah.

FYI, a node-locked vivado license goes for $3k

[tardy badger]

I’ve got more low temp paste coming tomorrow so I will try again

No, I meant ToS-wise

Anyway, here's a link if you want to make a generous donation to papa Xilinx:

Papa AMD

[raw jasper]

Force of habit

I just can't say AMD and Intel as far as FPGAs are concerned. Altera and Xilinx it is.

[tardy badger]

Just add it to the pile of money you’ll also throw at Altium

[raw jasper]

Also Cadence

[tardy badger]

Virtuoso is fun

I used it in college

[raw jasper]

I'd like to use JasperGold one day

[tardy badger]

Never used it

[raw jasper]

It's their formal suite

...formal verification

[ebon dew]

I'd love to have enough money to use Altium. Their software looks great and their youtube tutorials are amazing. Even though I use EasyEDA a lot of their lessons transfer over to any EDA software. Can highly recommend their youtube channel.

[tardy badger]

I’d love to see a major company just absolutely make it using and contributing to OSS tools

Like Adafruit

But like.. billion dollar unicorn

[raw jasper]

antmicro you linked the other day looks like an interesting candidate

[tardy badger]

Meta (Facebook) supports an open hardware platform

[raw jasper]

:\

[ebon dew]

Honestly EasyEDA covers most of my beginner'ish needs. It's only when you really start getting into multi-layer boards that the rules start becoming very complex.

[tardy badger]

They contribute hundreds of designs for open source arm based server blades

[ebon dew]

I'm not sure if someone as advanced as Skerr would like easyeda or not.

[dusty citrus]

Tbh I don't like any, they seem to be all stuck at the 90s, I'd like an Eda that makes my life easier, like I want a resistor of 100ohm, it auto gets the cheapest solution be a resistor or something else from a distributor or auto generate a trace design that work as a resistor

[tardy badger]

It’s called Open Compute Project

[ebon dew]

That would be cool Ly4c79.

[tardy badger]

Flux.ai seems to be trying to do that

[raw jasper]

Also this https://ms.componentsearchengine.com/

NOTE: Never tried it

[ebon dew]

easyeda does have something kind of like that with component library tied into jlcpcb but the amount of footprints to choose from often returns like 1000 irrelevant results. it can be frustrating.

yeah i usually have digikey open and jlcpb open when choosing components. i find something that both have, get the boards made, then assemble it myself using digikey parts.

except when they're too tiny like 0402 or less then i have to go with assembled stuff, which is another minefield of finding in stock components. end up spending more time searching for components and looking through datasheets than actually designing a circuit.

and naturally because i'm still kind of a beginner i end up messing up the circuit and skerr ends up saving me from a horrible mistake. 😛

[raw jasper]

I know nothing about PCB design

My only overlap with this community is FPGAs

[ebon dew]

it's never too late to learn

[raw jasper]

And I've played around with arduinos once

[ebon dew]

though you could say the same about me and not knowing anything about FPGA's.. that's a rabbit hole i really don't want to go down.

i'll leave the FPGA stuff up to the tape out kind of people, it's not something i enjoy.

[raw jasper]

You don't tapeout with FPGAs haha

"the tape out kind of people" -> I'm not even an EE

[ebon dew]

and, or, xor, etc.. no thank you.

[raw jasper]

If I can learn, you definitely can. If you want to, I mean

[raw jasper]

Join us! We get excited about multiplier blocks! :P

[ebon dew]

i don't. i played with redstone in minecraft, that's about as much as i want to learn about gates.

[raw jasper]

Oh, you don't need to do everything in gate level

Most things are done in the Register Transfer Level these days

[sand frigate]

Just out of curiosity, are there many RP2040 boards smaller than a QTPy?

[static flare]

I'm not sure the practicality of it, as with the QT Py RP2040, it does need components on both sides

[blissful roost]

https://shop.pimoroni.com/products/rp2040-stamp ?

[sand frigate]

That's interesting. I think the QT Py is smaller.

[blissful roost]

Ahh.... That's not "smaller", is it?

^^

My bad.

[sand frigate]

I think QT Py is like 75% of that

No worries, I don't actually need to know, I was just curious.

Looking at one and it's like, how could you even make one smaller lol?

[blissful roost]

It does have all the GPIO and 8MB flash though...

[static flare]

The QTPy RP2040 is smaller, 0.7"x0.81", as opposed to 1"x1"

[blissful roost]

Have you considered using just the RP2040 chip and integrating it into your project design?

[sand frigate]

Oh yeah, that's not for me, but would be really cool

[late fulcrum]

The XIAO RP2040 is the same 21x17.5mm size as other XIAO boards

[static flare]

I'm making something similar to the Stamp myself it seems, mostly so I have something I can just drop in without needing to source the components for an RP2040 each time

[late fulcrum]

I guess the XIAO is 280µm narrower than the QTPy, but 426µm longer.

I'd call it a tie, but technically the QTPy is 1.7mm² smaller...

[static flare]

The QT Py is supposed to be compatible, right?

[dusky estuary]

I don't have anyone else to tell bc nobody would understand how big of an achievement this is for me, but I was able to write a library for controlling ws2813b leds on a custom stm32 board 🎊

[blissful roost]

My dad is an absolute star.

Not only has he gotten me a blowtorch, but he's also gotten a little crucible. 🙂

I'm going to use them for melting solder to tin wires. 😄

[sweet rivet]

Had to do that for work, to get the timing right its not easy

[blissful roost]

Just need to fix the security camera wires.. and the bunnycam will be back in business. 🐰

[dusky estuary]

It was a bit confusing since its my first time using an stm32 and the ide it comes with. Pretty much it came down to configuring the clock correctly with the presalar and everything, and then setting up the DMA to use the correct pin to output the pwm signal. The big thing is making sure the timer is set to rollover at the end of one pwm period (pretty much the sum of the low & high times for sending a bit). Once that is set up you just feed the dma an array and it'll convert that into a pwm signal and send it over

Hardest part was debugging it without a scope lmao

[raw jasper]

Thanks!

[crystal ore]

If you don't want to invest in a scope, a cheap little USB logic analyzer can be very useful for this sort of troubleshooting.

[sweet rivet]

Yeah it is pretty weird how they implemented the communication to those leds on the chips itself. Not sure why they didn't use an existing communication protocol.

[sweet rivet]

Yeah that's what I did when I was working on them, for things like that they are very good

[dusky estuary]

Yeah I should probably get one 😅

Working on implementing 8 bit parallel for driving an lcd now

[acoustic pawn]

Somehow I watch about half (I counted and it's 11/29) of those channels as well lol

[dusty citrus]

Does anyone know if there are around cheap (like <50) sim banks board or projects? That can be interfaced with a computer over USB or anything else so it can be programmed?

[dusty citrus]

Likely I can just use a bunch of sim800 and switches, but I'd like something already made, and have more "channels" which wouldn't happen unless I do use multiple sim800 modules

[late fulcrum]

Why would you want to occupy all those cellular channels?

[raw jasper]

Seriously, I cannot think of any legitimate use for this. Why?

[dusty citrus]

I find easier getting a job posing as multiple specialized business rather than an all doing one

If that's aganist the code of conduct, I am sorry, I'll delete my posts

[late fulcrum]

That sort of trick is much more easily accomplished using VoIP or Ultra Forward

[dusty citrus]

I find voips to be annoying, because more than often they have been used for spam purposes, so if you call your client, you might go aganist a blacklist

[tardy badger]

stares at the voip system most companies use

[late fulcrum]

I'm working on some legislation to fix that: basically giving phone companies permission to not peer with networks that carry spam. My hope is that after a couple of weeks of flailing and shouting, the phone network will have fractured into two separate networks: one with the legitimate customers, and one with the spammers. And the legit VoiP companies will be strongly motivated to make sure they don't sell services to spammers, lest they get cut loose.

[dusty citrus]

Didn't ada fruit had a repo full of reference design of their modules?

[static flare]

Adafruit does have a fair number of their products on GitHub, usually linked via the relevant learn page, but I'm not sure if there's a overarching way to access them specifically

[late fulcrum]

I just go to https://github.com/adafruit and use the search function

[spice moss]

just to know there is almost time for spaceX starship flight test

[late fulcrum]

Wow, some scammers put up a "Elon Musk has an announcement" video that was one of those "send us cryptocurrency and we'll double it" scams. To youtube's credit, that one has already been taken down.

[spice moss]

could be same group who do that thing over and overagain

[late fulcrum]

I'm sure it is. I did ping their site with some forensics tools (not a real browser!) and was amused to note that the Certificate had expired.

[ocean sigil]

Nice pictures here https://www.youtube.com/watch?v=mhJRzQsLZGg until spacex coverage starts -- looks like they are targeting 0920 EDT (1320 GMT)now.

[raw jasper]

I've never actually clicked one of their videos. How is it convincing? Are they deepfaking the guy or something?

[late fulcrum]

There is a voice claiming to be Musk, explaining how he's controlling everything and it's guaranteed safe (yeah, right). I have no idea if it qualifies as a deepfake, as I'm too deaf to recognize voices anyway. There's a QR code pointing to their site, and the image is just a generic background shot of a rocket launch.

[tardy badger]

This happened to Linus tech tips YouTube page

They got session hacked and a stream was put up with that “Elon musk has an announcement” title leading to the double your crypto scams

[fierce prawn]

But they get it fix fast due to YouTube partner
Sucks if you are not one
Shows how injustice YouTube is

[tardy badger]

YouTube like all content platforms only care if you’re bringing revenue to their coffers

[fierce prawn]

Also discord
Support takes hours to respond

[tardy badger]

Exceptions being FOSS platforms like the Adafruit learn system

Though technically the learn system does also drive sales if you want to be technical, but the content is mostly driven by Adafruit affiliated people so it makes sense

[fierce prawn]

Reddit have a exception cz I can't judge it fully
Support is slow at requests but processing reports for message reports it's fast?

[tardy badger]

Reddit is driven by ad revenue mostly which they gather fairly even across all forums it seems

I’m not a Reddit user, I just occasionally browse threads

[fierce prawn]

And sometimes they don't respond but working to fix the issue in the background
Like last time is reported otp issue on my account and they fix it after 3days cz I can login after 3days

[tardy badger]

Interesting

[fierce prawn]

True

Do adafruit have a local reseller that have a shop in Houston?

[tardy badger]

Micro center usually sells some Adafruit stuff

[fierce prawn]

Got any microcenter near locksford street?

At any big shopping complex

[tardy badger]

🤷‍♂️

I don’t live in houston

[ebon dew]

The best place to purchase Adafruit products is through their store at https://www.Adafruit.com

[tardy badger]

Some people like to shop for Adafruit in a physical store and avoid shipping which is understandable

[sweet rivet]

They have maps on their site, micro centers are great for getting stuff locally, we have one here in north Jersey

[ebon dew]

but that would mean seeing people and interacting with them...

maybe i just have a permanent pandemic mentality now 😔

[tardy badger]

Humans need interaction

Pandemics are hard on society though

Not even from the perspective of death, but the separation and isolation

Thanks to some prepandemic stuff, the pandemic made my commuting anxiety far worse 🙂

[fierce prawn]

Are pcb allowed to carry on airplane

Even microcenter is cheaper than Malaysia

[tardy badger]

Yeah, I know a few people that travel with projects

[raw jasper]

It depends on the parts on the PCB

For some parts (ie. FPGAs), it may not be legal depending on the destination country

[fierce prawn]

Just a small piromoni rp2040
I already arrived Houston with four LEDs and two cell battery in my carry on

[ebon dew]

People travel with PCB's every day, everywhere, they're just in enclosures usually.

The only concern you'd have for air travel with any PCB is RF. If your board doesn't produce RF then no worries.

and even if it does... just turn it off or take out the batteries.

[fierce prawn]

With no enclosure though

[ebon dew]

should be fine, just don't have a bunch of breadboard wires dangling from it, security tends not to like that kind of thing.

[fierce prawn]

Should be fine cz I got two cell battery to pass in a bag full of led and wire

[patent hemlock]

if you're worried, declare it to the agent ahead of time and emphasize that it's a small project

[ebon dew]

i think someone on twitter recently went on board a plane with a custom pcb with 16 ESP32's, a wardriving setup. he was fine as long as he didn't turn it on.

[glossy knoll]

I flew numerous times with a clear plastic box containing a dev board and a whole bunch of wires connected to a display, various ports, etc. and nobody ever asked about it. Of course, I'm a white dude so there may have been some privilege at work there

[ebon dew]

yeah let's not go there please.

[ebon dew]

oh that's harmless, no worries

[fierce prawn]

But when I add a pcb into the mix?

[ebon dew]

still not a problem

just keep anything like that unpowered and you'll be fine

[glossy knoll]

I always had that stuff in my carry on (it didn't have batteries) so it went through x-ray and wasn't an issue at all

[ebon dew]

if in doubt just stow in a carry on bag

[fierce prawn]

Should I relocate or insulate that bettery

[glossy knoll]

LiPo-type batteries MUST go into your checked bag

[fierce prawn]

Cz they x-ray carry on too

[ebon dew]

keeping batteries separated in a cardboard enclosure is always a good idea

what kind of battery are we talking about?

[fierce prawn]

Coin cells

[ebon dew]

coin cells will have no problem at all

[fierce prawn]

So insulate that battery

[glossy knoll]

If you take the battery out of the board, definitely 🙂

[ebon dew]

i took my custom bluetooth sleeping mask on a plane with no issues.

but it looked like that

[fierce prawn]

That looks like a normal device @ebon dew

[ebon dew]

it is a normal device, only difference is i made it

[fierce prawn]

So to conclude
Just put all together with the LEDs?

[ebon dew]

yes coin cells with leds is fine. i would put the coin cells in a separate little plastic bag to avoid them from touching something

at the very least so they don't drain

but you could just leave the coin cells at home and purchase some in Houston at someplace like walmart

[fierce prawn]

I am already at Houston lol

Already passed through three custom checks

Malaysia - Tapei - Houston

[ebon dew]

then why are you asking now when you're already..

alright i'm gonna go work on some projects.

[fierce prawn]

I am asking for pcb

Cz it's a bit expensive and I scared about custom confiscating

[ebon dew]

how big is the pcb?

put it in your luggage or carry on

security is more worried about fruit and invasive insects than pcb's. don't even worry about.

like if you were asking "can i bring back this rare tropical fruit" that would be a completely different discussion.

[fierce prawn]

"Depth camera" might also be a useful search term in general, though I don't think Adafruit sells any of those. A very low-res variant would be some of the 8x8 ST FlightSense chips.

do u have a part number by chance, i see multiple

[fierce prawn]

All can

[limpid sedge]

oh ok, thanks!

[ancient rivet]

@limpid sedge if by comparable you mean size, then it appears to be a "micro" servo

[limpid sedge]

i mean by performance

and like power

[ancient rivet]

all these hobby style servos works pretty much the same way

[limpid sedge]

oh ok cool!

[ancient rivet]

like 5V power and the control signal is a 50Hz PWM

if you're trying to match output power, like for moving the control horn, the product pages should call out a torque

could compare those to what you already have

[limpid sedge]

yea it is within 0.1

is that a lot or negligible?

[ancient rivet]

0.1 what units?

[limpid sedge]

kgs

[ancient rivet]

kg-cm?

for example this one:
https://www.adafruit.com/product/169
says it is 2.5 kg-cm

[limpid sedge]

@ancient rivet yes

iirc the pic i sent one is 2.6

[ebon dew]

Everything to do with Servo's on Adafruit is in category 232. https://www.adafruit.com/category/232

[patent hemlock]

a .1 kg-cm difference is within the margin of error for most hobby servos

wait one sec

there are only 86 possible options for the height

[static flare]

Oh dear

[astral portal]

why am i trying to brute-force the 9999 code possibilities when i can brute-force the 86 height values?

i am big smart

[tribal brook]

ok. need a reminder. can you combine capacitors to get the right values? i need a 4700uF 25v and cant fund it on my usual 2 sites so want a back up plan

[crystal ore]

Yes, capacitors in parallel will add their capacitance. Though 4700uF is quite a big amount for normal uses. Are you sure you need that?

[tribal brook]

according to the schematic. its for train set power controller

i hope its ac cause i dont know if i can put an ac adaptor on a dc controller

[static flare]

If you want to convert from AC to DC, you can always use a Full Bridge Rectifier

[tribal brook]

this?

this is what im making

[static flare]

yeah, but it's backwards to how I'd normally think about it

[tribal brook]

p1 is input. personnally i would put imput on the left and read to the right

[static flare]

Same, that's why I said it's backwards to me

[tribal brook]

based on these 2 images, what is the output at track connection? is it ac or dc

[static flare]

depends on what S2 is

but I'd assume DC

[tribal brook]

a slide switch

[static flare]

Definitely DC then

[tribal brook]

so i need another converter after the track connector

[static flare]

if you want to work in AC, yes

[tribal brook]

i want to be able to work in both but i assume that that just requires a switch between this circuit and the adaptor, with the switch leading to the adaptpr and dc output

even if you dont use them with your qt they are very useful for any breadboard projects. in fact its a good idea to get extra

Thanks. Is there any way to use them on a breadboard without soldering?

[old beacon]

Umm. I think it is best to solder the header pins unless you have plans of using feather wings and stacking headers..

I solder mines.

[ebon dew]

I've been avoiding learning GIT via command line for a while now. Git Desktop can't do everything command line can. 😦

[fresh niche]

But....why?

[ebon dew]

I ask myself that all the time using command line. All the time.

[fresh niche]

But the command line is nice,it has a good personality :)

[ebon dew]

I like GUI and icons and clicky things.

[fresh niche]

Tbh i use cli so that i look smarter than i actually am

[ebon dew]

There's definitely some cred to it but I feel like I'm far more efficient with a GUI.

[fresh niche]

Welp it depends on person 2 person. But my pc is potato so no eletron guis for me :)

[ebon dew]

true, I could see CLI being better for systems that only want to initiate commands.

Gimping the GUI version of GIT Desktop not to have all the functionality of command line makes me.. kind of resentful I even started using the GUI in the first place.

If I would have started with CLI probably would have been better off by now.

Almost like GIT Desktop is a demo version and you have to upgrade to CLI... ugh.

[fresh niche]

But.....

Wait.....

Wdm by upgrade?

[raw jasper]

You could start using both side-by-side, defaulting to the GUI and falling back to the CLI when something doesn't work for you

[ebon dew]

installing python3.10 is like a 10 minute process geez

[fierce prawn]

Some commands are unavailable on git desktop

I already know all git cli command (almost)

[fresh niche]

Wait i thought git desktop was for non technical ppl who dont use linux

So like

I am still confused

[red prairie]

Could anyone help me in #tinyusb I think I should have asked here to begin with

[fierce prawn]

I use git desktop when I am late

So I use a mix of cli and that

[fresh niche]

Ah i see

Frankly i dint even know a gui git existed so lol

[honest jolt]

...theres also this...

[fresh niche]

Yea lets stick with cli.....

[patent hemlock]

i use "both" - my primary dev environment is IDEA, so it's got @ebon dew 's "clicky" stuff and i use the CLI - the primary pull/push/branch/commit stuff is usually in the IDE because that's where i'm "working", but there's a bit of CLI that happens as well

[honest jolt]

It's hard to remember all the commands in for the CLI unless you use it often (which I'm not since I'm using an IDE) But sometimes I pull up the terminal and run simple commands like git push or git pull cause it's faster than waiting for the UI to load.

[fair summit]

not really, sorry

[patent hemlock]

well, speaking of Git - when did the web UI change? I swear it didn't look like this like 2 days ago?

[raw jasper]

web UI? Are you talking about cgit, or github.com?

(neither of which are associated with git in any official way)

[patent hemlock]

yeah - the web UI at github.com

[ebon dew]

I also primarily use the web UI and github desktop (windows). Using GIT from command line is not user friendly. I spent hours trying to get everything setup and then at the end it said sorry this method was deprecated in 2021... in CLI. I wanted to throw my computer out the window.

[fresh niche]

As someone who uses git from command line,it is very user friendly if you use a unix system. Idk why but on windows its terrable

[old beacon]

i am still learning git. 🐌 slowly though..

[patent hemlock]

because the API was designed by Linus, thus follows GNU/Unix design patterns, which are not well supported on Windows

[delicate stream]

ChatGPT is so dumb

I “made” this “game” by screaming at it for the last few hours, lol

I should make a video on this... it really highlighted the flaws of using it for code -- for one thing, it can't always give all the code at once [this "game" was 170 lines all in all, but only like half that could be output at a time] so you have to ask it to re-post parts; but sometimes it changes it when it gives it to you again. Plus when you ask it to add something, sometimes it randomly changes other things; like, I had it to the point where it was the red and green blocks on the screen, green could be controlled with the arrow keys, and I told it to make the red block go towards the green at 1 block width per second; it did that, but removed the code to control the green block. Silly dumb things like that

[honest jolt]

[raw jasper]

Oh, these days using a script which automatically screams at it for hours while draining your credit card in the form of OpenAI API fees seems to be all the rage :P

[ebon dew]

It doesn't have to work, it only needs to make them money.

I wouldn't have thought that was a possible thing yet here we are.

and the thing that actually works (twitter) people don't want to pay access for. strange times.

[raw jasper]

To be fair, the scripts I'm talking about are not official openai products. And I haven't tried them, so I may be overexaggerating. As for the whole "pay for twitter" thing, without going into details, I feel it is unrelated to whether it "works" as a product or not.

On an unrelated sidenote, I'd gladly pay for a subscription to social media if it exempted me from datamining and advertisements, things that, as far as I know, are not included in any of the current subscription offerings by mainstream platforms

But thats all Ive heard from her really. I havent seen a bad one yet. The local production of Godspell was OKAY at best. Id want to see it again, but in a different place.

It wasnt awful though.

Its different when you see people up on stage live.

Sometimes they even interact with the audience and break the fourth wall

[delicate stream]

And sometimes things go hilariously wrong XD

[wanton thistle]

Yea, things happen. The show must go on. But usually even small productions check everything out

If gps satellites only send information and don’t receive, how could they possibly prevent its use for guided missiles

[crystal ore]

Previously the signal was purposefully degraded, so you couldn't get the full accuracy without an encryption key. Now the signal is open, so the laws restrict the accuracy of commercial GPS chipsets under missile-like scenarios (high altitude and high velocity). It wouldn't stop a serious attack but it would prevent a lot of improvised ones.

Having tired of the emphasis of most modern headphones on bass, I'm looking to spend some money (up to ~EUR100) for a more... unbiased ("flat"/"reference") listening experience. Any suggestions?

[acoustic pawn]

I wonder if you can just use a software equalizer. Audiophiles will probably disagree with me though

[raw jasper]

It helps that I'm not an audiophile :P

Actually, there exists software that is supposed to do this exact thing
https://www.sonarworks.com/soundid-reference

Not cheap though

[fresh niche]

Any beyerdynamic headphone would work

[acoustic pawn]

Maybe you could make something by ffting a signal, modifying the amplitudes of the frequencies, and feeding it into a reverse fft

Not optimized but it’ll probably work

[fresh niche]

Wouldent that ruin the highs tho?

[raw jasper]

I'd probably need a good microphone. Also, I feel I'd pay the headphone money in time

[fair summit]

i have AKG K240, which are fine. I too dislike heavy bass. But I really long for something like Sennheisier HD414's, which I got in the 1970's: on-ear, very light, crisp. I could wear them for 8 hours with comfort.

[acoustic pawn]

No. As long as your sampling rate is high enough. 44100Hz is more than 2x the upper limit of human hearing, so it’s fine

[raw jasper]

Thanks for the suggestion! Sadly, the K240s are open-back, which means they leak, which wouldn't work for me

That's on me for not being specific enough :)

[acoustic pawn]

You can probably do less, since music rarely has extremely high frequencies

In terms of the fft idea

[fresh niche]

Are you looking for just audio quality or overall a good headphone?

[fair summit]

Sony MDR-V6 (7506 similar)

Sennheiser HD280's recommended, but I have not tried them

[hard estuary]

I am a fan of the Sony MDRs for a clean, balanced sound

[fair summit]

there are counterfeit Sony's out there, so buy from a reputable place

[fresh niche]

The hd280s have a high clamp pressure. Will prolly give you a headacke and red ears

[raw jasper]

I found the MDR-V6 for $400. That might be more than their weight in gold 😅

The HD280s are more affordable, and seem to have a good enough frequency response profile, at least according to https://www.rtings.com/headphones/1-5/graph#299/7903

Thanks for the suggestions!

[fair summit]

ugh MDR-V6 is discontinued; MDR-V7 has "more bass kick" 😦

MDR-7506 I think is really pretty much the same

"professional", but not expensive

@raw jasper ^^

Haha, cable damage seems to be the #1 failure mode for my headphones!

[quaint marsh]

For what it’s worth, I’ve owned and abused many 7506s for many years and never had a cable failure.

[ebon dew]

@tight copper No, the pins are on the wrong side for JST-PH or JST-SH. The little rectangular locking tab is on the bottom in your image where with stemma it would be on the top.

It's almost like some kind of reversed JST-SH connector where the locking mechanism is on the opposite side. It looks very close though you're right about that.

I have a PR submitted for the 3D model, there are many compatible variations. I think the image you shared doesn't look like it would be compatible, it's a thinner connector. Very very similar but I think if you actually attempted to use a stemma qt plug in it you'd find it doesn't quite fit. Here's an image of a QWICC/STEMMAQT port.

[wanton thistle]

anyone else have a habit of planning new projects while currently working on something? Its like the brain needs a new shiny thing to think of 🤔 😅

There are PH right angle connectors btw

SH is a different style JST connector, just like XH

[ebon dew]

Yes, I didn't do a model of that. I needed the model because it was the only component missing when doing 3D PCB renderings of the TR-Cowbell. 😉

[tardy badger]

Difference is spacing if the pins.

[ebon dew]

Oh they're saying it might be PH not SH. I think that one would also be known as the grove connector?

[tardy badger]

The connector in that looks like a Pico blade though

But hard to tell for sure

There are so many that look similar yes. Search digikey and you'll probably come up with hundreds of similar variants.

[gusty pilot]

A few notes here:

1. As much as I hate Sony and refuse to buy their products, the others here mentioning the MDR-7506 and similar are correct that it's a good pick. Side note, fresh out of the package they smell terrible but that fades quickly
2. Flat frequency and phase response are just not possible in a headphone format currently; there are too many variables, including ear shape, exact placement, etc. That said, I completely understand wanting "more flat" than "less flat", which is totally doable
3. I tend to go for the Status Audio CB-1. They are affordable, albeit somewhat cheaply made, but I take care of my gear like this and haven't broken any yet. They are about as close to name-brand reference headphone sound as I've found in an off-brand set of cans

@urban arrow also we do have a #show-and-tell channel where you can share project updates

i have just discovered that foo[x][0], foo[x][1] actually works (foo is a dict of tuples)

This is a generalizable thing. foo[x] returns whatever that value in the dict is, and you can do whatever you want to it afterwards... if it's a tuple you can index it, if it's a number you can operate with it, or if it's a function you can call it like foo[x](y), even.

Hey everyone! I have an idea for an LED watch, but I have no idea how I would design the PCB and what components would be needed to achieve what I want. Are there company's out there where I can be like "this is what I want and what I want the watch to do" and they design it?

[crystal ore]

Yes, definitely. Although they won't be cheap, since you're going to be paying for their engineering time, etc. But if you're planning to take the product to market, it can be worth the investment.

[cloud pilot]

Did anybody have recommendations? I'm so new to this I don't know where to begin lol

[crystal ore]

I can recommend some firms, but before I take the trouble, I'd like to establish that you really want to invest tens of thousands of dollars into this project... 😅

A cheaper alternative might be to find an individual freelance engineer on a site like Upwork.

That'd be more feasible if you're looking for a one-off prototype rather than an industrial product.

[fiery quarry]

There's also how protective are you of the idea and if you put it out here weather someone would pick it up as a fun project

[dusty citrus]

why is that I can get sim800l core modules from aliexpress for about 3 dollars, while I can't get for less than 7/8 dollars the sim800l module itself, from the distrubutors?

[acoustic pawn]

Possibly counterfeits, scavenged modules, factory runoff, or buying in bulk and reselling single items for the lower per unit bulk price. There may be something else, and these are really just guesses. I don’t really know how those ultra cheap Ali electronics exist because often the parts (and sometimes even the main IC) cost more than the product.

[acoustic pawn]

The cheapest option in terms of money is to do it yourself. It’s also really satisfying to finish a project that you built from scratch. But it is a really big jump and may not be worth the time if you don’t know much about electronics and this is the only project you might do.

And some interested hobbyist may pick up the idea if you put it out here

[split light]

Electrically, is there a difference between these?

I mean, I guess they are. I think I'm just being paranoid

[static flare]

I don't really see a difference between them, unless the capacitance is different

[crystal ore]

Yeah, they're equivalent at the schematic level. Obviously if the wire in one is a mile long and the other is an inch long, that would be a difference, but to a first approximation only "what is connected to what" matters.

[raw jasper]

Sorry to interrupt, but would you mind replacing the fancy characters in your nickname with their equivalent Latin ones? Even though they are visually similar, this is not known to computer systems, and a person using a screen reader would hear something to the effect of "CJK UNIFIED IDEOGRAPH-4E59 CANADIAN SYLLABICS CARRIER GO (and so on...)", instead of the intended "ZMAN350X". Thanks in advance!

[static flare]

Yeah, I feel schematics exist in a non-physical sense of equivalence, which will probably end up making something I make fail

[raw jasper]

I mean, schematics tend to describe topology and component values, not implementation

[static flare]

Yeah

[crystal ore]

Yeah, professional schematics will often have "layout notes" written on them to explain things that matter beyond just the connection toplogy.

[raw jasper]

On an unrelated sidenote, I find it interesting how KiCad was inspired by Eagle's color scheme as far as schematic capture goes

[dusty citrus]

Someone has suggestions about what to use to get for cheap 11 uarts?

[late fulcrum]

I'm not sure if you're physically asking for traditional UARTs (chips that connect to a processor bus and provide asynchronous serial communications), but if you are https://www.jameco.com/z/TL16C550CN-Major-Brands-IC-TL16C550CN-UART-FIFO-40-pin-DIP_288809.html is a possibility

That's the Motorola/MOS style one, they also offer Intel style (8250) and RCA style (1854) UARTs for the same price

You can also get current production 65C51 chips from Mouser for $6.57 apiece if you buy at least 10 at a time https://www.mouser.com/ProductDetail/Western-Design-Center-WDC/W65C51N6TPG-14

[ebon dew]

My low pressure system warning came on this afternoon and sure enough there was a large storm out there. It works. 🥳

[tardy badger]

Do you also check for rapid pressure changes?

Since those would typically indicate strong super cells

[ebon dew]

No just a floor & ceiling as hurricanes and tropical storms are typically slow moving. I would only really want to a rapid change algorhithm if I lived in tornado prone areas.

[tardy badger]

I mean, Florida does get a good number of tornadoes though not nearly as many as the Midwest

I remember tornado warnings all the time in central Florida when I live there

[ebon dew]

This is true, tornados can happen anywhere.

[tardy badger]

There have been two recorded tornadoes where I live lol

We typically don’t see strong storms like that in Utah

One last year and the other in like 2000 or 2001

Opp 1999 not 2000/2001

[ebon dew]

My weather station updates every 15 minutes, it's not a real-time kind of thing.

[tardy badger]

Ah

Makes sense for low power

[ebon dew]

I'd have to change the polling rate to something like every 1 minute but then I might have issues with wifi disconnects, server not responding, etc.. 15 mins works fine for me.

Well compared to the Magtag's once per day, every 15 minutes is almost real time. It's on a power hungry TFT with a 10000mah battery. Might last a day or two on battery which is all I really need to go through a hurricane with it (which I have twice).

[raw jasper]

I mean, if there were a super cell, wouldn't a broadcast notification be issued?

[tardy badger]

Usually

[ebon dew]

Plus I'd have to do time based code checking for last pressure reading vs current pressure reading. For some reason I really don't like dealing with that kind of code. All my code does is check the pressure, if it's over/under a certain value it alerts.

Exactly ningen, the emergency broadcast system would make my phone scream anyway for a tornado.

[tardy badger]

If you’re in a rural area, tornado warnings can be very ambiguous. Detecting steep changes in pressure could be very helpful

[ebon dew]

By the time it detects a steep change the tornado is probably on top of you?

I have no experience with tornado code. All my project code is on github, if someone wants to add tornado code they'd have to do that themselves. I'm not the right person to play with that kind of code. Tropical storms & hurricanes on the other hand yes I've gotten pretty good at detecting them up to 50+ miles out.

and it's only like 2 very basic lines of code

the sensors do all the work. credit where its due, it's really the adafruit modules and their module design that's allowed me to get my project to this point.

[wanton thistle]

Oh, what are those storms called where there is a quick drop of pressure and its basically unpredictable? Derecho? It may be called something else. But generally, I dont think those can be predicted. They just kind of happen. We've been getting more and more of those... 😬 😨

Microburst! Thats it

[raw jasper]

I wouldn't know. We don't have them where I live.... yet

[ebon dew]

I wouldn't mind putting tornado code in my weather station if I knew someone else was running it. I think I'm the only one... because you can't get the TFT Featherwing anymore. Been out of stock for more than a year.

While it is publicly available code on github pretty sure I'm the only one using it this way. I do have plans to update it to a 7" 40 pin display soon though.

[raw jasper]

Next step: telnet over wifi interface

[fierce prawn]

Just use the gov apis

[thick wind]

Is it something that can be ported to the esp32 tft feathers?

[ebon dew]

Yes it can be ported to pretty much anything with a TFT but you'll lose the pretty graphics designed for the 3.5" display.

Current iteration of the project is running stable on the Feather ESP32-S3

https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Boards/espressif/Adafruit Feather ESP32-S3/3.5 TFT Featherwing/Online OpenWeatherMaps Weatherstation

[raw jasper]

hey, that's a nice, clean display!

[static flare]

The screenshot is 404ing but nice

[ebon dew]

thank you 🙂 been working on this one for a while now.

I use the adafruit_bitmapsaver library to take actual screenshots from the device onto an SD Card then transfer that to the PC via a card reader.

That's a real screenshot from the feather of the actual display output.

as you can see it's big, would be pretty hard to squish everything into a built-in feather TFT. :/

[thick wind]

Ooooo that is nice. Could probably use https://www.adafruit.com/product/2050 in place of the featherwing...

[unborn sphinx]

remove redundant information

resize components

[ebon dew]

redundant?

the blue labels are the weather in NY, the orange labels is the weather in Florida. 😉

@thick wind That would be acceptable yes. I just like being able to plug any feather directly into the back of the display. Hmmm I could design my own PCB featherwing TFT with that display.

[unborn sphinx]

don't need to display that at the same time, cycle it every few seconds

[thick wind]

That's a design decision one can make to their own taste. For smaller displays, it can save a lot of valuable space, but a 3.5" display like that can comfortably display them side-by-side.

[unborn sphinx]

True, my answer was in response to...

[unborn sphinx]

this ☝️

[thick wind]

Though having some kind of cycling can improve the life of such a project by reducing the risk of burn-in.

Ahhhh

[ebon dew]

that's a good point. i did have the background images changing at one point. removed it. with the S3 can add it back in.

it's a work in progress like anything else 🙂

[dusty citrus]

Ok so I have multiple sim800l to be used under i2c, each module has the same adress
How could I reprogram each addresses for each module, without reprogramming everything individually by using jumpers or whatever?

[late fulcrum]

I don't think the SIM800L supports I2C, I thought it was an asychronous serial device. Do you have a pointer to the documentation about an I2C interface?

[dusty citrus]

Page 42/43
https://www.manualslib.com/manual/1747481/Simcom-Sim800l.html?page=42#manual
Although I am not so sure

[thick wind]

Function isn’t supported in its standard firmware, so unlikely you’ll be able to get this to work.

[dusty citrus]

Huh I didn't notice that, so I am stuck with uart?

[late fulcrum]

Yes, I think asynchronous serial is the only option available. Note that if your MCU has multiple UARTs, this may not be a problem. If not, you can perhaps use SoftwareSerial to talk to some of them. Failing that, you can use (digital or analog) multiplexer chips to share an asynchronous serial port among multiple devices.

Note: I ran into a similar issue on one of my boards, where I had multiple devices that used serial communcations. I ended up choosing a chip (MSP430FR5969) with multiple UARTs.

[dusty citrus]

I also realized that 2G here doesn't exist anymore
There are no cheaper alternatives than the sim7000g (20~35€)?

[late fulcrum]

Yeah, I kind of wondered about that. My old project with the similar SIM808 modules has the same problem (however, they aren't completely useless, as the SIM808 also includes a GPS receiver)

Alas, I'm not aware of any name brand cheaper 4G/LTE or better modules (uBlox and Quectel make some nice ones, but they're more expensive than the SimCom ones). I did find this Quectel knockoff on AliExpress for US$16 https://www.aliexpress.us/item/3256804023817154.html but I'm dubious about it.

[manic rain]

https://www.ehow.com/how_5598263_make-own-permanent-magnets.html
Does anyone have experience making their own magnets? Is it really necessarly to align the object with N-S of Earth?

[late fulcrum]

There are three usual ways to magnetize something magnetizable, this is sort of a blend of two of them. One is to heat it above its Curie point in a magnetic field, then when it cools below that point, its atoms will tend to maintain that magnetic alignment. Another is to physically bang on something in a magnetic field, the mechanical effect will jostle some atoms to align with the field. The last is to expose the object to a very strong magnetic field, which will bring the atoms into alignment directly (there are small magnetizers available to do this for things like screwdrivers, and some larger electromagnet devices used to magnetize objects like flywheels for magneto use). In all these cases, the comparatively weak field produced by the Earth's magnetism is easily overwhelmed by a stronger magnet close by.

In short, there's no particular need to align the object with the Earth's magnetic field.

[manic rain]

Which of the three methods you describe produce permament magnets? Only the first one?

[late fulcrum]

They all can produce permanent(ish: the field reduces somewhat during the first week) magnets. The first and last are generally the most effective.

[tranquil swallow]

The first one sounds easy enough with an induction heater

[late fulcrum]

The problem with an induction heater is that it produces a powerful oscillating magnetic field, so you'd have to shut down the induction heater and then apply a continuous magnetic field while the object cools. An oscillating magnetic field is how a demagnetizer works.

An ordinary propane torch works too, for many materials

[limpid sedge]

whats the acceleration limit on https://www.adafruit.com/product/746

[acoustic pawn]

I think Helmholtz coils are often used to provide a strong and straight magnetic field. The aligning with the earth’s field part may be because the earth’s field lines are straight compared to the field of a strong permanent magnet

Helmholtz coils solve that by having two coils that make the field lines straighter in between the coils

[late fulcrum]

For the PA1616 module itself, 4G. I would guess the breakout would be the same.

Data sheet here if you're curious https://drive.google.com/file/d/1qRh-sf5UiobH6Udk-N1_fyKjUmWYsam8/view the acceleration is noted in §2.6, "Specification List", on page 12.

Theoretically, it shouldn't be hard. Express casein (milk protein) in a bacterial system, purify the product and.... mix it with water? The result would taste of cement though

It'd probably be better if lactose or glucose were added

Fun fact: Lactose-free milk tastes sweeter to us because free glucose tastes sweeter than the glucose-galactose combo that is lactose

[raw jasper]

For example, GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky (view source at ION.org). However, their accuracy worsens near buildings, bridges, and trees.

High-end users boost GPS accuracy with dual-frequency receivers and/or augmentation systems. These can enable real-time positioning within a few centimeters, and long-term measurements at the millimeter level.

From my limited understanding of Apple’s “Find My” location tracking, they use a combination of GPS, Cellular, and WiFi to give really precise location. I think it’s been in use since the iPhone 4? I don’t know if that’s the same as what you’re talking about though

Would it work

[manic rain]

I have cut 7.5 x 1.7 cm piece from a steel sheet, sticked one end to the magnet from hdd and hammered the other end 40 times. The piece is magnetic but can only lift about 1 gram. Can I make it stronger with this method?

[late fulcrum]

It depends on the phone. Generic USB is good for up to 500mA, but phone USB may be even less than that, phones aren't really power banks.

[late fulcrum]

That may be about the limit. Most steels don't maintain a very strong permanent field, and the mechanical method doesn't really align the majority of magnetic domains.

My phone draws about 1000+ amps on normal charge

But as soon it charges
The miliamps adapt to a range to 700-1000+

O_o

did your house burn down?>

[glossy knoll]

Step 1: cut end off EV charging plug
Step 2: touch leads to phone

I got an 11v RC battery and attempted to hook it up to the receiver wrong. It shorted the receiver instantly, melted plastic, and almost blew up the battery.

The JST-XH terminal end on the battery melted, thankfully unplugged it before the metal contacts melted together.

[crystal ore]

Ooof! Yeah, a lot of those RC battery packs are designed for extremely high currents, so they won't cut off when shorted before they dump 100A into whatever they were hooked to. Gotta treat them with serious respect...

[ebon dew]

Yes, I was surprised at how fast it melted. Whole incident happened within 1 second, if I was slower with my reaction time the battery probably would have blown up in my face.

They're wicked powerful little batteries.

Here's a stupid question: Would this (https://www.adafruit.com/product/1566) work well for powering a (5V) Lego light kit? I'm looking for a rechargable battery pack that I can shove under my coffee table when not being charged so it reduces the chance of tripping over it.

Forget Mili

Miliamps

[ebon dew]

@unkempt cairn I don't know anything about Lego power requirements but that seems like it will put out a constant voltage of 5V no problem especially since it has 2 ports.

10000 miliamps is a pretty sizeable capacity too. Depending the on current/amperage draw of the Lego electronics I'd expect that size to last for hours if not days.

You can run a 1 Amp load for 10 hours with that battery. 500 miliamp load for 20 hours, etc...

[raw jasper]

That sounds horrifying! I'm glad you're OK!

[unkempt cairn]

That's what I was thinking as well.

[sacred crypt]

hi guys

anyone here that used VL53L1X sensor?

[patent hemlock]

i just had a psychotic bing chat - it was ... weird
one of the last suggested links was "Lets write a story together" - i was trying to diagnose some linux sound issues :🤪

[ancient rivet]

that's sort of how linux sound troubleshooting goes

[ancient rivet]

yes. nothing fancy though. just basic usage via the adafruit arduino/circuitpython libraries.

[ebon dew]

Only thing horrifying about it thankfully was watching my brand new RC receiver pop and fizzle with electricity. My workshop still smells like burnt plastic. 😦

[cloud frost]

Is there general discussion support here for using vscode and adafruit feather M0? I need some basic pointers to get my adafruit lib includes working ( in this case for VL6180X )

[raw jasper]

The question is, what's worse, smell-wise? Burnt capacitor, or burnt plastic?

[raw jasper]

Oh no, linux sound strikes back :(

[cloud frost]

To answer my own quesiton, I was able to

    adafruit/Adafruit BusIO@^1.14.1
    SPI
    adafruit/Adafruit Zero DMA Library@^1.1.1```
To get the main dependancy libraries in place, but I could not find VL6180X lib up there, so had to hand import that one 😦

[patent hemlock]

apparently linux sound is still so bad it made bing psychotic

[raw jasper]

Reading pulseaudio docs drove the bot mad......

[dusty citrus]

I'm sorry someone is able to tell what font is this? font finding tools seem to fail due to the res

[lean summit]

Looks like Arial or Helvetica to me

[ocean sigil]

😉

[fresh niche]

dont forget ´feature : its a bug but we 2 lazy to fix it´

[umbral phoenix]

this https://www.adafruit.com/product/2890 but for Pico

[ebon dew]

A bell doubler is now a good idea with so many bells out there. Same for QT Py BFF's.

pico to featherwing, QT Py to featherwing would also be nice.

defeats the purpose of going with a pico or qt py instead of a feather yes, but should maximize compatibility across platforms so users aren't penalized for going with 1 form factor over another and then to have their project goals change. i would honestly buy some.

[dusky estuary]

I have successfully recreated a $270 product for less than $20. Only took about a year of work 😅

(Tape wont be in the final product, will use the actual adhesive on the led strip lol)

This is the one they're selling 💀 https://freefalldatasystems.com/coloralti

[jovial rock]

D'oh! Hours of hair-tearing fun all for an errant underscore.

[rapid geode]

now im in trouble...

[ebon dew]

Should bring that on Show & Tell! Cool project!

[raw jasper]

Nice project! Just make sure to remember to dim them LEDs before actually using them in the field, because these look blindingly bright :)

[dusky estuary]

Oh ofc! Right now just have them set to be on the brighter side to make it easier to troubleshoot. Planning to go outside tmr and find an optimal brightness for direct sunlight

[worthy magnet]

Designing the PCB is hard

I hope adafruit people make a

• IDE? maybe?
• ...Maybe ESP-01 for Japan.

[dusky estuary]

If you haven't already, check out the Flux pcb designer. I haven't used it a ton myself yet but it looks promising in terms of simplicity

I personally use Kicad for everything and haven't had any problems outside of mistakes caused by myself not paying attention 🙂

[worthy magnet]

I use KiCad

Soon™️

I wish Adafruit TFTs are parallel :V

[dusky estuary]

Nooooo parallel is terrible why would you want that 🤣

[worthy magnet]

Why not?

It's faster

[dusky estuary]

I just had to scrap a whole pcb bc I couldn't figure out how to use a parallel display lol

Its faster if you can figure out the datasheet

Ig the adafruit ones probably have good docs

The one I used was off of digikey and didn't 😦
