general-chat

[rapid geode]

not labelled though

so.. ?

[violet parcel]

I'm confused too, information lacking but the numbers seems to be the same as the datasheet

but it's missing the mapping between the schematic and the physical pins

and here you go @dark heath https://learn.watterott.com/silentstepstick/pinconfig/tmc2208/

v2 in there with the pinsout and explanation

[dark heath]

Ohh wow!

thank you for the help! So the unlabeled pin was motor voltage in. the store page of it fills in some of the details, it runs 4v-36v.

[violet parcel]

schematic might be handy too to compare with the datasheet on page 9

[dark heath]

ah yeah, cool

@violet parcel thank you so much! probably saved me a lot of headache!

[violet parcel]

no problem, still don't assume the extremes and be careful

seems that you have a clone of a waterott chip that is detailled where I linked

so not everything might be 100% perfect

[dark heath]

yeah, I have a couple of these drivers and I'm just trying to learn the whole setup, so if I accidently fry something it's not the worst thing ever. But these added schematics do give me more confidence.

[violet parcel]

wish I could find something like this for r/c 😦

instead it seems I have to buy a pricey ESC(which contains various chips/drivers) and reverse engineer it(by checking the PWM pulses, IF it's PWM)

[dark heath]

What kind of R/C?

[violet parcel]

an offroad and/or cralwer, want to be a self-driving one with camera etc but to do anything with it I have to be able to override the transmitter/ESC

ie: even if I tell it to go forward with the remove if the sensors sense something in front it shouldn't go forward and should stop while I'm driving if there is a problem

My plan is to spend around 150$ to get a basic kit to see if I can interface with it and if it works eventually get an scx10

[dark heath]

ah cool. I only do quadcopter RC builds so I don't know if I could help. Custom R/C vehicles seem more technical/involved

[violet parcel]

yeah seems electronics and r/c of any kind are 2 worlds completely apart

but in drones/flying rc at least you have open protocols like opentx

[dark heath]

yeah that's what I mean, if you can solder and do some basic circuit debugging then drones basically build themselves 😄

[violet parcel]

but that doesn't work well with a r/c car/truck unless you completely reconfigure a taranis remote or such

[manic stone]

hi all, what are you using to store things like arduino, sensors etc
I have one box and it start gets a bit busy :/

[violet parcel]

fishing box

they ve been making them for 200 years so most of them aren't crappy stuff with no though on usability like the electronics box on amazon etc

[manic stone]

huh, looks like a great idea ....

[violet parcel]

yeah seems weird a first but some of them comes out like stairs and with separators so you can configure it

some are waterproof, some have plastic pockets with clips you can put cables in and usually a large box this all goes in for space for kits/multimeter/glue gun etc

i have two plano plano 620310, one for home and one with reserve material for when I go to a maker lab

[dusky estuary]

So I'm a skydiver and I just got certified to do night jumps. Anyone have any cool neopixel ideas? 👀

I wanna make something

[manic stone]

you could solder pixel on your body and add an accelerometre and make them flicker towards the direction you are leaning
like pointing towards the direction you are leaning for others to see you

it could even be cool to have a full boddy led matrix that might be more condence on your back and hands and legs will be just lines

[dusky estuary]

Yeah doing a neopixel shirt would be so cool

[violet parcel]

A transponder so ATC can see you as well as night instruments as a helmet hud

[dusky estuary]

I've thought about making a helmet hud

Only problem is ar optics are pretty big

[manic stone]

ofc, you can go more advance and add a GPS on it so you can see your flight on Google Earth ( you can see altitude and speed and geolocation

[dusky estuary]

Ive actually already done that haha

[manic stone]

aw,

[dusky estuary]

I made one that would track the speed & altitude over time

[manic stone]

can I use your code for the KML? I am currently working on that

making a GPS tracker for motorbike

lol

[violet parcel]

could have a constant display of what your kinetic energy and terminal velocity will be when you hit the ground 😄 🤣

vs your current potential energy

[dusky estuary]

Yeah I mean it was pretty simple, the gps provided all of the data

I just used the gps featherwing

I can send the sketch if you want though

[violet parcel]

I have the visual aid system that airport use to land in land (when they have lamps flashing around the runaway with arrows) but I can't think of a way this could be done on skydiving

[manic stone]

DM

[violet parcel]

navigational lights like planes would be kind of funny too

especially if you calculate an higher led during the fall to give the impression you are flying level

[dusky estuary]

Yeah I was thinking that lol, would be hilarious 🤣

[violet parcel]

I don't know much about skydiving but don't you have some control over how fast you go/where you land ?

[dusky estuary]

Yeah you do

I was thinking of making something that could change colors either depending on speed or altitude

That could be super cool

[violet parcel]

maybe a real-time calculation of the current conditions and what you have to do to land at X

[dusky estuary]

Ooh that could be cool

[violet parcel]

ie: what angle/speed to set to etc, like if you were a missile (you kinda are thought, more like akin to a finned free fall bomb)

[dusky estuary]

Meat missle 😎

[violet parcel]

could even have laser guided skydiving, friend lase a target and you try to land at it

[dusky estuary]

GBU-69

[violet parcel]

don't know what's possible just throwing out ideas

but the laser and nav light things sounds cool to me

[dusky estuary]

Yeah those are all cool

Synchronized lights across multiple people could be really cool too

[violet parcel]

Also inspect for hidden cat before flight

[dusky estuary]

🤣

[violet parcel]

keeping a log of the flight and something like integration with adafruit IO too maybe

[static flare]

New Discord update ruined my notification settings

[signal drift]

dang thingiverse even knows if I am using pihole to block ads 😦

[dusky estuary]

What type of display would be the most visible in daylight?

[crystal ore]

E-ink, transreflective TFT, old-school monochrome LCD. Basically anything which mostly reflects light instead of being self-illuminating.

[dusky estuary]

Thx

[gusty torrent]

A bunch of people on another server I'm on were saying that their microphone settings were toggled between voice-detect and push-to-talk too.

[lavish river]

Hey I could do with some help, is anyone available? <@&617066238840930324>

[crystal ore]

The rule of thumb is to just ask your question in the most appropriate channel, and anyone available who knows the answer will hopefully chime in.

[violet parcel]

Ed is it just me or some peoples use discord like it's a forum? Leave a message and don't answer any followup probing questions?

[whole jacinth]

you're not obligated to continue helping if they don't answer follow-up questions

[violet parcel]

oh it's not about obligation, it's just that I don't understand why someone would think this is a forum

[lavish river]

have a matrix portal which i would like to showcase an animated gif on, could anyone guide me on how to do this please..

[violet parcel]

I'm trying to put myself in their shoes but I see it so often and have no idea what's going on

[whole jacinth]

maybe they're not familiar with the platform and the expected patterns of interaction

[violet parcel]

does the discord have somr sort of forum interface that let one post a question here and read it from the forums ?

[whole jacinth]

i think there isn't one, and it seems like a large amount of development and maintenance effort to create one

[tardy badger]

Works so far, just need to SWD some firmware

Which I need to figure out

[violet parcel]

I see another feature nearby in the pic, birds of a feather flocks together ?

[tardy badger]

yup haha

just a bare board i was testing something on

apparently 3.3V in and DEC3 are internally connected on the nRF52811 and presumably the nRF52840 which was a surprise to me

[late fulcrum]

There's a helpful article about that very subject here: https://learn.adafruit.com/animated-gif-player-for-matrix-portal

[dusty citrus]

I see it every day on more than one Discord. People ask a question and that's the last you hear from them, or they say two or three things then vanish. I just look at it as part of the territory, and check myself from replying further. ;)

A singing Miki figure!

[ebon dew]

yep that's why i named my feather enclosure as the flock box 😁

was going to name it bird box or guilded cage but then saw something on the adafruit site advertising feathers that had that in it and was like ohh flock box sounds much better.

so figured out which font they were using and came up with my own logo based on it 🙂

[ebon dew]

Ohh there’s a new game of thrones series starting tonight called house of the dragon. 🧐

[rapid geode]

game of whats?

never heard of it

[late fulcrum]

I think it's from that book series George R. R. Martin did after Wild Cards.

[rapid geode]

they should cast sean bean as the star and then kill him off right away

[ebon dew]

Yeah my brother read the books and he wasn’t a fan of the series. Having never read them I found the tv series amazing.

[hasty wedge]

Here's the PCB for that figure

It uses a Nuvoton 8051 MCU to generate audio

Ik the transistor's direction is incorrect according to the silkscreen, it's needed for this new firmware version

[late fulcrum]

I'm kind of surprised a firmware change reverses a transistor, I wonder if the real reason is they changed to a different transistor with a different pinout.

[violet parcel]

wish I had a feather but I still have a lot of soldering left

[hasty wedge]

Actually, that is the real reason

[fair summit]

No, we don't have that, we just have https://forums.adafruit.com, which is completely separate. As for posts without followups, they could be away for a while. I'd give them the benefit of the doubt.

Today Was my first day at my new electronic school

[ebon dew]

figured out why i haven't been getting adafruit emails for a while. was a bit overzealous with email filters and regex'd the entire .ru tld. usually not a problem unless you actually want to receive email from a domain that has ru in it... like adafruit. apparently it didn't care that i only wanted ".ru and pushed adafruit to dev/null right along with it.

[arctic folio]

escape ur periods

[ebon dew]

yeah escape characters worked thanks. it's because i used regex instead of contains and periods are treated as wildcards 🤦‍♂️

[topaz jay]

I'd like to send a big thank you to the community for helping me with my first ever LED/electronics art project! I've gotten a ton of useful help from the #help-with-hw-design and #help-with-projects groups.

If anyone is coming to Burning Man, I invite you to come see it! It is a large LED-lined heart with a microcontroller talking over Bluetooth to two heart rate monitors. The two sides of the heart will beat to the two heart rhythms, and the game is for the two people wearing the heart rate monitors to try and synchronize their heart beats.

I'm at Celestial Bodies, 7.30 & G. First drink is on the house. (and 2nd, 3rd ... nth drinks too! It's Burning Man!)

[dusky estuary]

They're so helpful! Wish I found this discord a few days earlier, would've saved me a bunch of money 🤣

[ebon dew]

@topaz jay Submit it to the adafruit blog after burning man with some pics!

[dusty citrus]

im new to coding where can i learn?

[tardy badger]

Pumpkins and my sole watermelon

Grown with old fashion tech

[rapid geode]

nice

[tardy badger]

I have like 12 total pumpkins, pretty excited for them to continue to ripen 🙂

[violet parcel]

are you gonna put electronics/LEDs in them gor Halloween?!

[tardy badger]

Nah, these will get turned into pumpkin pie 🥧

They are pie pumpkins 🙂

[rapid geode]

mmm pie

[ebon dew]

got a new soldering iron 🙂 my first real hakko

now i have something compatible with the 3D printing heat insert tip

though i did use my old iron to smudge 2 of them in there np, was just an excuse to upgrade. had the old soldering iron for like 10 years.

[ancient rivet]

@ebon dew careful with the temp setting buttons on that one. read the manual - it's sort of counter intuitive what they do.

[rare gulch]

When was the last Adabox shipped out? The last unboxing video I can find was back in December.

[tardy badger]

Winter 21 was the last one. Chip shortage has made adabox hard to do

They assure us that another is coming but it might be a while before enough parts are available for the scale of adabox

[late fulcrum]

It is possible to do both... 🎃

[tardy badger]

I go to the local pumpkin patch and buy the largest pumpkin I can carry for $5

Usually being 40-50lbs lol

Which is a lot of pie

[ebon dew]

@ancient rivet thank you will do. first soldering iron where you actually do need to read the instructions.

i'm used to turning the knob until the solder starts melting. now i actually have to look up the temp specs when different solders melt and stuff.

[spiral zephyr]

How do I get help with an order? I ordered $80 USD worth of products and DHL is trying to charge me $80 to import it into Canada…how can I get them to ship it back to you?

[rapid geode]

ugh

this is not official help, but maybe i can see if its correct or not.

dhl will apply HST (13% in ontario for example) PLUS up to $19.99 brokerage.

[stray wind]

Please email [e-mail] with order inquiries. We have no way to help with orders here.

[spiral zephyr]

They charged $49.50 for ‘Excess line fee charge’

[rapid geode]

so, in theory $80usd should only have up to $33 total

oh

well thats weird

[spiral zephyr]

Is there a way to call?

[stray wind]

Unfortunately, no.

[rapid geode]

sounds like maybe they botched the category? thats what happened to me today with dhl. (not adafruit) Got hit with a tarrif where there shouldnt be one.

[spiral zephyr]

Sigh. Ok, I guess it’ll get shipped back.

[rapid geode]

Why njot email them, they should be able to sort it out

they used to use ups and ups would add illegal brokerage and adafruit credited me

[spiral zephyr]

I’m emailing right now, but I doubt they can do anything about the charge. It’ll be a DHL issue.

[rapid geode]

Not necessarily

[spiral zephyr]

Ok, I’ll give it a try.

[rapid geode]

(also dhl is responsive, they fix stuff for me alot)

ups is the evil one haha

[spiral zephyr]

Ok, thanks. I appreciate the response.

[rapid geode]

just a few things to know so you are armed with information: brokerage fees over $20 is illegal, and they cant hold the package hostage.

no matter what they want to claim

most likely this is just a category error though, it happens a fair bit

[spiral zephyr]

The response from ADAFruit was ‘nothing we can do, here is a link to the faq’

[rapid geode]

thats not quite true, but i would ask dhl for an explanation of the charge.

[spiral zephyr]

I paraphrased. “Please accept the package and pay the customs and duties required by your order. We will not be able to refund your purchase if you refuse to receive the order. For more details about shipping, see our Shipping FAQ here: http://www.adafruit.com/shippinginfo/“

[rapid geode]

ah i see

yes. generally you want to get a refund vs rejecting it. weather it is from adafruit or dhl

although you should ask dhl what exactly it is first

[violet parcel]

you can ask for self-clearing but you'll have to wait hours on pĥone and be prepared (research it on like cbc). And you'll have to go to a CBSA to self-clear it but at least what CBSA charges will be transparent

DHL also generally charge a 15-20$ fee for handling customs even if there is nothing to do

[rapid geode]

thats not the issue here it seems

they have tacked on an extra specific fee

they need to explain it

[violet parcel]

yeah that seems like it: "Multiline Entry Importing shipments containing multiple commodities Multiline Entry Charges apply when more than 5 lines are recorded on the customs clearance, for example with different commodities or different countries of manufacture. Per Line 4.50 CAD per line after 5th line"

[rapid geode]

ooooh

but how many different things can be in an $80 order?

[violet parcel]

And this is also exactly why I avoid buyting on adafruit and most US sellers

because it's really the canadian customs/shipping roulette that made so many victims

SO I'm going to keep a link to this next time someone argue that I should buy a 1$ chip to solve a problem and they don't understand the difficulty when it ships from the US 😄

(that's also why I don't accept gifts from the US either)

[rapid geode]

ha

i use digikey for adafruit mostly cause i want it next day

but this is a definite benifit - not dealing with this

[violet parcel]

digikey has a warehouse in Canada and they handle all customs / shipping stuff if you order over 75 us$

[spiral zephyr]

Yeah that’s a good suggestion.

[rapid geode]

yeah, unless diginey doesnt have it in stock, they are the better option for adafruit

[violet parcel]

I'm sorry this happened to you, you get bitten once and you are twice shy after that

for me it was a shirt from Liverpool from the UK and there was a 600% customs fee

[rapid geode]

clothing is a whole ball of cats

[whole jacinth]

yeah, customs and couriers will each try to extract money from you, often more than you think is reasonable, just for the privilege of touching your shipment

[violet parcel]

the silly thing is that it's so much that for 2 shirts you might as well travel first class to the UK

and import it manually in Canada, it will be less expensive

[rapid geode]

ha

livignston charged me like $400 for brokerage on my cnc. but that is a more special case

2 cnc's actually on one truck

[whole jacinth]

yeah, baggage/personal exemptions can help. unless the customs officials catch on that you might be trying to abuse it for business…

[violet parcel]

my guess on your charge is that someone was exceeding verbose or there boss was watching over and askked them to write a novel like they were JK Rowling or Stephen King

[rapid geode]

i thnk the exemption is $300ish on flight

[violet parcel]

Back in the university I had diplomats family I knew from africa who'd carry my stuff in diplomatic pouch for a small 10-15$ donation to their family throught western union 😄

[rapid geode]

well thats just fraud

ha

[whole jacinth]

taking advantage of sovereign immunity like that is kind of next level

[violet parcel]

Diplomatic pouch are exempt from search and any legal proceedings

as per diplomatic immunity

[rapid geode]

ive never found it to be any benifity to try and skirt the customs rules. i know so many peole that get angry when they get charged tax

as if it was their right to dodge it

[violet parcel]

bah you can see it that way if you want, but they are perfectly allowed to use it for friends or to buy a non-taxed bottle of wine locally and share it with friends

it's not like they were offering that to the general population

I'd guess if I follow your logic I'd have to refund all the wines I ever drank at their home as well and imported food items

[rapid geode]

....

[spiral zephyr]

This is what I’ll do next time. I guess I’m just frustrated because it feels arbitrary and non-transparent. There has to be a way to make it clear to customers what they can expect.

[rapid geode]

well this is out of their hands. this is a dhl weirdness. either a screw up, or maybe you ordered something odd

[spiral zephyr]

Define ‘odd’ 🙂

[whole jacinth]

out of curiosity, which shipping options did you select? did it include DDP?

[rapid geode]

Odd, i mean like, clothes, a plushie, books. things that arent just a micro board

[spiral zephyr]

I selected DHL but there was no DDP option.

[spiral zephyr]

It was a data logger feather wing, imu, qt display and some cords. $50USD, $26 shipping, and now $78 in fees from DHL.

[rapid geode]

k that makes no sense then

[spiral zephyr]

So $200 Canadian…

[rapid geode]

must be a mistake

youll need to try and call dhl

[spiral zephyr]

I’ve emailed them; of course like ADA you can’t actually phone them.

[tardy badger]

DHL has a chat

Online chat bot thingy

[rapid geode]

yes, and i have definitely phoned them

[spiral zephyr]

They directed me to an email.

[rapid geode]

ha

[tardy badger]

Wild

DHL has been hit and miss for me at times

[spiral zephyr]

Well, it is what it is. I’ll just wait and see.

anyone know where they sell holographic lenses?

[manic stone]

hi all,

like on the ESP, does the RP2040 ( pico ) has the option for OTA FW update ?

[tardy badger]

The Pico W might

[manic stone]

or even better Pico + GSM module ?

I am building a GPS tracker, and I am trying to think how can I deliver OTA FW updates :/

[tardy badger]

You might be able to deliver through GSM but it would likely take some finagling

[manic stone]

hm.... sounds challenging

[tardy badger]

You might use the gsm module to toggle the rp2040 into boot mode, get control of the flash, write a new UF2 to flash and release the flash back to the rp2040

Then toggle the rp2040 reset

I’ve not tried this so I’m not sure if it would work

[late fulcrum]

I'd look at Edmund Optics and maybe members of SPIE, the International Society for Optics and Photonics.

[crystal ore]

Those tend to be fairly specialized custom components, since they have to be designed for particular wavelengths and geometries. Are you sure that's what you need? It won't be like "this is a magnifying glass but it's super-thin!"

[unkempt cairn]

Done!

Anyone know a good electronics shop somewhere in northern manhattan? Or near there? Thanks!

It's been a while, but I swear she was at one of the first makerfaires in NYC.

[bright veldt]

I want an optical setup that takes light from an lcd screen and projects it far away. While the entire setup is very tight

[crystal ore]

That's going to be difficult, just from a brightness perspective. But you might look into Fresnel lenses, as they can be fairly large and thin.

[fair summit]

@bright veldt https://www.surplusshed.com/ is an interesting place with a lot of optical components.

[jolly briar]

hi , did anyone here had some experience with mcp2560 CAN bus module ?

i am interested in doing some project with it on CAN bus network

[violet parcel]

do you have a car or truck or semi ?

[jolly briar]

sadly no but am going to get a salvaged ECU

but i can use my friends car for testing

[violet parcel]

can bus is mostly used for full-size vehicles (and a little industrial machines control)

it's going to be hard to find projects imho and no you shouldn't mess with your friend car electronics ...

[jolly briar]

i want to decode some packets and have some fun with it

[violet parcel]

also imho putting the can bus on i2c kinda defeat the purpose

[jolly briar]

@violet parcel lol i have certification in car Diagnostics

my idea is to provide more open source mean for vechile diagnostics

for altering some values in ecu you pay fortune

[violet parcel]

yes that would be extremely useful, it's one of the factor of why I don't buy a car yet

I don't want to pay 1000$ a month to even know how to repair my car....

[jolly briar]

someguy already done some project like it

can i share links here want to show you something

[violet parcel]

if you also invent something that quickly open the window when the car fall in water, that's my biggest fear in a car, especially now that with electronics the button wont work in water 😦

[stray wind]

Yes but don't post a bunch in a row. The bot will think it's link spam and stop you.

[violet parcel]

When I say there are too many chips in a car that's one of the thing I mean... 😦

[stray wind]

You can post multiple links, but leave some time between the messages.

[jolly briar]

its a youtube link for a guy does a project similar what i am talking about he also uses arduino and some board called makkina or something

[stray wind]

That should be fine. Go ahead.

[jolly briar]

https://www.youtube.com/c/RANDASH

[violet parcel]

I had a guy at work that had a webpanel so he knew the state of everything in his car including where it was

I assume he did this with canbus etc

[jolly briar]

can you connect me with him lol

[violet parcel]

I left this place about 4 years ago I don't even remember their name 😦

It's the kind of situation where you think you know electronics and you can have a 1hr discussion then they pull out something like this that seems to work

And you find out the other person is like at the electronics olympics level and all your accomplishments in electronics were for nothing and you are a total noob compared to them 🤣

[jolly briar]

well that is how i feel when i meet some folks from Machine language club

i started learning recently i am planning adding it to the project

[violet parcel]

previous neighbor also had most of his house automated, I can't even begin to understand how to could interface with their stove for instance and asked them (couldn't find any stove that would let you do this)

and he was like, oh I just replaced all the electronics in it

If I did something like this I'm pretty sure most of my country would burn down accidently from it and I'd be fined several billions

[jolly briar]

sounds awesome

where is your country region i mean

asia ?

[violet parcel]

canada

[jolly briar]

is there lottery program open now days most of my country youth traveled there

[violet parcel]

What's the most awkward for me is when they talk how they did it and how easy it is

But for me I don't even know to even remove a screw from my stove

So several pre-requisites steps seems impossible for me

And 240V is very scary to me

I wouldn't even do it if someone held a gun to me

[jolly briar]

i dont mess with AC as well but when i need i do

i installed some outlets on my own and fixed some stuff on my own

i only have experience with DC

[violet parcel]

I still remember the tone of their voice when they said "oh it's easy, just replace the electronics and you can do whatever you want" 🤣 😦

[jolly briar]

i just try be carefull

well you can beat them as long you are here in these community Adafruit is about learn and share right

you just go to online course or read books then go to technical school

and make earn out of it

[violet parcel]

but adafruit is still mostly about electronics, most peoples here dont know about 48V electricity or r/c etc

[jolly briar]

i stuided computer science at college to make an earn i had to study electronics and vechile diagnostics course

[violet parcel]

for me it's when peoples are expert at several things at once

and book learning isn't enough to provide a working item, you need experience too

like I blew an LCD because I didn't know leaving it for hours would print the text into it

now I know so I use a motion sensor to only display when it detect someone and turn off the screen after 30s to prevent burn-in

[jolly briar]

motions sensor sends signal to where the electronics inside or relay to power inlet?

[violet parcel]

that's why technical school usually 2/3 of the hours of the course are in a lab

[jolly briar]

coool idea

[violet parcel]

I don't do anything with mains yet, send signal to the electronics inside, read by arduino to power on the LCD pin

[jolly briar]

technical school and practical experience is important

LCD how much size ?

[violet parcel]

There is a kind of "debouncing" the motion sensor has in if the detection was for too short it power back the LCD for much less time

in case I just do a quick check on it

16x2 LCD

and here when they teach electronics it's for industrial use

so they don't really talk about arduino or pi

but about PICs and the related gear and logic controller that are big console to control powerful fridge-sized motors etc..

I bought a couple of used books from vocational schools because imho university are too much theory or you need math prerequisities to even understand what is written (for instance the MIT opencourseware videos)

I mean, I just want to know how a capacitor works, I don't want to do an quad-integral on maxwell equations to figure this out...

[jolly briar]

i watched the mit opencourswarevideos for electronics 101 and got a copy of the book its really fascinating

i have completed bout 60% of the book due to some circumstances i halted the study

father decased

[violet parcel]

mostly went over my head, they lost me when they started showing maths. Saw some symbols I didn't even know were part of maths

[jolly briar]

what course you took ?

[violet parcel]

sorry for your loss. version on youtube where the lecturer was explaining that basically all the courses at MIT on electronics are about understanding maxwell and in 101 they did an overview of it

he'd circle some of the equations and says which course covered it etc

becfore that for me maxwell was a kind of coffee

[jolly briar]

@violet parcel its alright

I'm pretty sure its different course , the instructor was retired Navy Tech Professor , he is awesome you should see the book everything simple no much math actually all division and products https://www.youtube.com/watch?v=SpqwAasxY7U&list=PLFt_ar31D2E8T1kACn_Y9akyObmH2GHP6

sorry videos named mit course but its a Washington college course

its awesome book you will not regret it

Following up on the customs charge issue I posted about yesterday. It turns out that DHL charges a $4 fee for every item over four items in their customs processing. I was able to get them to wave the fee, but this basically makes any multi item order to Canada, shipped through DHL, completely unaffordable. And, as a provider to an electronics focused business (who sells lots of small parts)…unacceptable. I emailed ADAFruit about the issue as a heads up; customers should be notified of this practice by DHL before ordering.

~ASK AN ENGINEER 8/24/2022 LIVE! https://youtu.be/rlV4nm9Ot50

[rapid geode]

but i thought you only had like 5 itesm

also not sure about that cause i just made an order (not adafruit but with dhl) with like 50 items and only got the $20 charge

i need to call them tomorrow though and get a duty reversed. got charged on something that should be duty free.

grumble

technically not adafruits problem, sounds more like dhl trying to find a clever way around the law on brokerage fees

(law states that unless terms are agrees prior to shipment, they can charge a maximum of $20 brokerage)

ups still breaks this law constantly despite being sued and loosing twice

i have settlement cheques from them

hey there,
Do you guys know the name of that "loop/tube" what are usually use for bycile counting.
It is a tube in tube, and with pressure creates contact.

[fair summit]

https://diamondtraffic.com/ "road tube" is pneumatic. Is the system you're asking about electrical or air-pressure? Link also talks about a piezo system.

I know most of you aren't local to Florida but the Artemis launch is going to be a big deal down here.

1. The point of the vehicle is to get back to the moon which has always drawn large crowds and inspired generations.

2. This is the biggest rocket ever launched by NASA.

[spice moss]

ESA service module boost it

[ebon dew]

If you're traveling in the area expect traffic jams even on major highways. If it's a cloudy day visibility could be limited to 5-10 miles which is why people clamor to get as close to the launch site as they can. If you have a military ID you can bypass a lot of the public traffic and get straight onto the base where there's plenty of parking and good visibility.

We got to collect sand dollars that were perfect and not crushed by tourists

That was until we walked too far in one direction or the other and tripped of silent proximity alarms and had MPs drive out on ATVs and ask us to turn around 🙂

Hi folks, I want to build a CO2 sensor that'll integrate with Homekit. What platform should I use? I've got a https://shop.pimoroni.com/products/scd41-co2-sensor-breakout?variant=39652270833747 so something that supports QW/ST would be great. I think that this library is the right one for homekit? https://github.com/espressif/esp-homekit-sdk

Sounds like ESP32 is the right way to go, but there are a ton of options. Any suggestions?

[burnt tendon]

...which probably crushed a whole bunch of pristine perfect sand dollars while they were doing so.

Oh, hi @tidal lance!

Have you considered ESPHome and Home Assistant?

[tidal lance]

Home assistant is a no go, needs to be native. Also OMG HI HOW ARE YOU

I ended up buying a FeatherS2 board which has ESP32 and 2x QT on it, and seems fully featured. I imagine it'll be pretty good if not overpowered for my purposes.

[burnt tendon]

Fancy meeting you here and stuff. 😄

But, yah, I like ESP32-based home automation projects far more than Pi-based home automation projects partially because you don't need to get implanted with an explosive device and sent to NYC in a glider to rescue the president in order to be granted the ability to purchase a Pi in the middle of a component shortage but mostly because they behave far better when you yank the power.

[ebon dew]

Ordered 2 feather S2's because the S3's are obviously not stable enough yet. I don't really need dual core or bluetooth for a weather project anyway.

[tidal lance]

lol you have a “master punners” role 🥲

[burnt tendon]

This is something that you, of all people, should not in the slightest bit surprised by. 😄

(For those not in on the joke, @tidal lance worked with me a few jobs ago and his desk was right next to mine and so he got a full force stream of puns 5 days at week)

I'm mostly using Feather ESP32's still because even the S2's aren't stable enough yet, LOL. ESPHome and WLED are both much happier on the ESP32.

(Also, because apparently the Adafruit discord is a giant roving internet party of like-minded individuals, he's not even the only person who has worked with me who is on here)

[tidal lance]

Just more amazed that the role exists. Did they create it just for you?

I was on the Pimoroni discord before but it’s rather anemic in comparison.

[stray wind]

It was created specially for a different community member, who is now a mod, so they no longer show up in the punners list. Then, after an epic pun-run one day, we added more folks to the role. And now here we are.

[burnt tendon]

My goal in life is not to ever get so useful so as to be a mod or one of the helpers so I may retain the role most suited to me.

[tardy badger]

Lol

Installed a new hose holder and hose on the side of the house today. Feeling productive.

[rapid geode]

i installed a new fork on my bike

might be a liiiiitle too big

😛

[rapid geode]

ha

that fork belongs on a different bike which is out for warranty repair so i got bored

😛

[ebon dew]

that's not too big, your frame is now just too small 😛

[rapid geode]

too bad you cant scale it like in 3d

[ebon dew]

good luck with a 3d printed shock

[rapid geode]

should totally work.....

man, i fear the price of printing the lowers in titanium

[ebon dew]

i actually have a frame very similar to yours. it was a hans someone edition.

[rapid geode]

hans rey

[ebon dew]

was my brothers, he doesn't ride anymore

yeah that's him

[rapid geode]

i may or may not have more than 1

:x

[ebon dew]

good lord

[rapid geode]

the vinatge one is at my friends brothers house. trying to figure out how to resurect it.

1995 model

or 96

[ebon dew]

yeah i think my brothers is about that age too

[rapid geode]

we could sell all the parts on ebay for good money ha

[ebon dew]

it's yours if you want it.

[rapid geode]

ha, nah, i have too many as it is

but those frames (i assume a zaskar) are in high demand

valuable

[ebon dew]

he's been telling me to donate it for years but seems like a shame to give it to salvation army or whatever, would rather it went to someone that will use it as intended

[rapid geode]

nono. donating is good, but not to some junk pile. needs to be brought back to life properly

[ebon dew]

yeah my 2nd thought was just leaving it out in front of a bike shop

[rapid geode]

you got a pic?

[ebon dew]

not handy no :/ it's in the corner under a bunch of my mechanic stuff

[rapid geode]

haha

hans rey edition karakoram was 2014. hmm

[ebon dew]

has some cool 3 spoke carbon fiber wheels, zoomy looking things

[rapid geode]

spin wheels? ha i had those

[ebon dew]

but 1 is cracked and i guess that's why he gave it up. they were expensive.

[rapid geode]

they were so crap

but so cool

[ebon dew]

yeah he figured out quick they were no good for trials

he really like trials stuff the most

[rapid geode]

the spin wheels are made of nylon. hypothetically repairable with a soldering iron

[ebon dew]

oh, look like carbon fiber kind of design

[rapid geode]

yes, carbon in nylon (instead of epoxy)

formed on a gallium meltable mold core

really cool stuff

[ebon dew]

yeah i literlly have to move my 2 ton engine crane to get at it

[rapid geode]

they were actually wheel chair racing wheel they adapted for mountain (and i think tyey made a bmx size too)

was it that?

hmm, thats 2005

hes had his name on so many of them haha

[rapid geode]

1995/6 zaskar. mag 21 SL, xtr, magura hs22 brakes.

mmmmm

thats worth real money

together or apart

[ebon dew]

he has a disability now, can't ride anymore. everyone gets old.

[rapid geode]

aw

[ebon dew]

think he was like 16 when he got it. time flies.

[rapid geode]

expensive bike for a 16 year old. ha

[ebon dew]

yeah, for sure. he worked for it though.

[rapid geode]

well, should figure something out with it. its literally worth a few grand, so dont toss it.

[ebon dew]

woah

[rapid geode]

ha yeah

[ebon dew]

i don't think the shock is good and rail is busted. like the only thing still good is the frame, handle bars and seat.

[rapid geode]

that fork is super rare

[ebon dew]

the rear rail whatever that thing is called

[rapid geode]

rail?

[ebon dew]

cog wheels on the rear from trials crunching on it i think?

i dunno what it's called

[rapid geode]

derailleur/

?

[ebon dew]

yes that

[rapid geode]

if its dark grey it is xtr (like the crank)

those are $50-$200 used. alone.

ha

[ebon dew]

i dunno, already piled all the stuff back on top of it and put my crane back 🤷

[rapid geode]

hahahaha

anyhow, point is, it is valuable, and you either put it back together, ot just flip all the parts individually.

but dont bin it

[ebon dew]

he knows all the stuff about bikes, obviously i know pretty much how to peddle them

[rapid geode]

haha

[ebon dew]

he's the one that kept telling me to donate it. i honestly don't think he wants to see it knowing he can't ride anymore.

like just looking at it is a sore spot or something

[rapid geode]

ah

so the fork isnt worth much. its a quadra 21r, nor mag21. but even still $100-200.

(i sold all my vintage stuff last year)

[ebon dew]

i'd like for it to go to a kid that's really into trials that might not be able to afford one.

[rapid geode]

yeah

[ebon dew]

i think my brother would like that

[rapid geode]

if it can get reassembled.

and tuned

[ebon dew]

are they still relevant for trials?

[rapid geode]

sorta kinda

people do still like those brakes

[ebon dew]

or haven't been made obsolete by some new tech

[rapid geode]

obsolete is relative

does it work? if yes, its not obsolete

🙂

[ebon dew]

yeah he saved up for a while for the shock and the brake system. they were additions.

true lol

well i mean for some kid who wants to get into trials.

i knew him getting those spin wheels was a stupid idea. he wanted to shave some weight and regretted them. they actually added weight and were really expensive.

he was heart broken when he cracked one of them.

guess he was hoping they'd be sturdier than regular wheels because he went through a couple of them too.

learning to do trials he'd always come home with something broken. he got pretty good at it though, impressively good.

could climb stuff taller than me like he was a cat.

well if you know anyone that intends to use it for trials let me know. i'll ship it to you no problem.

just want to make sure it goes to the right place.

[rapid geode]

yeah they were heavy and floppy

well GT tried to deny my warranty on their messed up frame. this is going to get entertaining. they tried to claim that replacing the back wheel voids the frame warranty.

ha

ha

...

ha

[ebon dew]

how does replacing a wheel have anything to do with the frame? unless you got hit by a car?

but then that's frame damage... not wheel damage.

[rapid geode]

they are trying to dodge

it wont work

"you changed something so we arent responsible"

but thats nonsense

[rapid geode]

ha, so its not even the wheel. apparently i said i put a larger tire on and that made me notice it was bent (never even rode it). the larger is the "modification".

that is even dumber

[hollow crystal]

Who else goin to TypeError

[rapid geode]

O_o

is that on a subway?

[burnt tendon]

Oof, I got tickets to the Silicon thing that was getting advertised on Adafruit and but... now I'm not, because they decided at the last minute to lift some of the COVID precautions.

[cloud pilot]

does anybody know what outputs on my feather m0 i could use to control a servo? im currently using D4 and its working fine, however i need to add another servo to my board and want to know what other chanels i could use

I'm trying to refer to this chart but D4 isn't even on the pinouts listed on the feather M0 express that's on adafruits website?

[late fulcrum]

Pun intended?

[late fulcrum]

The learn guide points out that nearly all the pins support PWM and would presumably be suitable to control servos.

[cloud pilot]

its really strange, i got SCK to work, however when i use A2 ,3 , 4 it speeds up my codes pace

audio is sped up and so is frequency of other loops

[ebon dew]

@late fulcrum no actually but as soon as i hit enter and looked at it i was like ummm didn't mean it like that but still funny.

[dusty citrus]

TIL the stupidest lock switch system
they place a bar between the switch and two support, then in one support they place a lock that doesn't lock anything, but it's there just for aesthetics

so they could easily remove it, and place the switch on

you would say who is that nuts who would remove it after seeing all of that
maybe a kid, or a competitor of some kind? since if there are incidents, all the company is shut down

[violet parcel]

a lock that looks like it's locking system will turn away most opportunity theft, as in "I look at it while passing by to see if I should come back when I have more time". For more money you can have one that seems difficult on close inspection but isn't actually that should should stop most close inspection. For even more you can have that is easy to open, and so on and so on. Even if you have the best lock in the world it's away security vs ease of use vs what's locked vs the value of the lock

to give an extreme example unless you have a 400000$ vault you can't stop someone with a crane and a wrecking ball that can be rented for like 3k$ a day with any lock

[violet parcel]

looking for a recipe app that support meal pictures, parsing recipes sites, ingredient cost/total recipe cost, meal planning that is web-based or allow import/export to/freom android and windows with 1 license. Any idea ?

[violet parcel]

what do you mean?

[blissful roost]

It's from Futurama.

[violet parcel]

ok I dont watch low-budget indie movies/tv series

[blissful roost]

Bender gets annoyed, because he can't go into the theme park..
He says something like "Fine! I'll make my own theme park, with blackjack and censored!"

Errr.... Futurama was a Matt Groening thing.
The guy who created The Simpsons and Disenchantment.
Certainly not even close to low-budget/indie.

[violet parcel]

I just didn't get the reference, wasn't translated so I wasn't exposed to it I guess they prefered to show a translated alfie for the 200th time than buy new movies/tv series to translate

[blissful roost]

It was on many major networks in different countries.

[violet parcel]

hosting prices annoy me so much

I wish I could stick to windows but until I'm a millionaire it doesn't seem possible and none of the cloud sellers have a spending limit

[hasty quarry]

So I just watched a proof of the Euler-Lagrange equation

I’m going to cry

What did I just watch

[violet parcel]

wasn't it proven long ago ?

[blissful roost]

My former employer is doing a discount on generic webhosting, so I might have to consider that.

[hasty quarry]

……….

Is that a joke?

I’m sorry I can’t really tell

[violet parcel]

no?

wasn't it proven in 1750 or so?

[hasty quarry]

Oh

I’m confused here

I said I watched the proof

What is your train of thought here

[violet parcel]

When I was in CS they asked me to prove cantor, to this day I wonder why they asked us that since it was proven by Cantor in 1851 or so

what's the point of proving equations used for centuries or already proven?

[hasty quarry]

That still makes no sense

Why is this a logical response to me saying I watched the proof

As in…”huh, I wonder how to prove it”, looked up a video, and watched the video

[violet parcel]

It's just that to my mind it seems more useful to know how to use it or use it than watch a proof

I don't really care for the proof of ohm, knowing that it only apply to really specific conditions anyway, I just use it

[hasty quarry]

That’s like saying programming is useless because using products is more useful than knowing where they come from and understanding more techniques

Or engineering, or anything of the sort

Nonsense

[violet parcel]

And it's probably wrong anyway as per QM just like newton is wrong, so I'd contaminate my mind watching a false proof

Kinda like when I learned to prove pythagorean theorem in 6th grade and found another property of geometry from it and the teacher pretended to gratz me but what I had "discovered" was figured out 2800 years ago

[hasty quarry]

Um…yeah, you absolutely discovered something

Just because you didn’t invent it

[whole jacinth]

figuring out a proof without knowing a prior one is definitely worth something

[hasty quarry]

Doesn’t mean you made no discovery

Having the “but that was done before” attitude while learning math makes absolutely no sense and counteracts the process of learning math entirely

[violet parcel]

Sorry I guess, just never saw the point and I'm still not over it after 10 years of being out of school and this is what I disliked from math the most and the reason why I didn't go past undergraduate level since every things I deduced from a proof had been discovered before

[blissful roost]

It's not for the sake of "proof".
It's to show that you understand.

[whole jacinth]

it takes a lot of education and study to begin to prove nontrivial mathematical facts that haven't been proven before

[violet parcel]

And I realized you need a ton of money as well to discover science because even basic experiments today costs hundreds of thousands (like binding two particles together to see quantum superposition)

[hasty quarry]

But why do you refuse to see the value in your efforts proving those things? Going “that was done before though” with work that you objectively did to apply yourself is counterintuitive to the maximum

You grew, you experienced

That’s always something to be proud of regardless

[violet parcel]

eh I'm quite proud that from the 6th grade I could bust the myth that medieval peoples believed the world was flat

since that was discovered 2000 years before the medieval era and there is no way anyone educated wouldn't know pythagora

[blissful roost]

Actually, there were people in the period that did believe such

It just wasn't accepted as fact by any majority

But you should also know that the vast majority of people were not educated.

[violet parcel]

wanted to do a phd in materials science but I can't even solder smd so...

[blissful roost]

And as we see today.. it's very easy to fool uneducated people.

[violet parcel]

and my school made superconductive rods with femtosized crystals...

so I didn't feel good enough to do something with something so small

[blissful roost]

That's what she said.... ?

...sorry

[violet parcel]

I expected that joke and decided to not modify my statement 😄

[blissful roost]

🤪

[violet parcel]

same thing with aerospace, I get very intimidated when I see two integral symbols next to each other or with second order differential and above

especially when I'm told that it can't be calculated so we have to estimate it

[blissful roost]

I'll stick with IT. lol

[violet parcel]

First time I saw such an integral I was stunned

didn't even know that was legal and assumed a typo

[ebon dew]

I’d rather not hear the words aerospace and estimate together. Those are two things that shouldn’t go together.

[violet parcel]

well I have bad news for you 😄

[ebon dew]

😄

[violet parcel]

also that is why planes costs so much because at 1/10000 of a cm tolerance each blade in the turbine costs 70000$

I know because I practiced on rejects that were only a micrometer off that were given to my university

[hasty quarry]

💀

Oh man

[whole jacinth]

the key is knowing the relevant tolerances in each context. estimation is totally a thing for flight ops

[ebon dew]

I never did get to see X-rays of the 3D metal printed rocket bell housings nasa was experimenting with.

[violet parcel]

I asked the very same thing to the state engineering cert guys and they said when they make a bridge they use a 25-30% margin because they know that newton isn't perfect

and that materials can't be perfectly measured and assume ideals conditions

even in electronics the same sensors will measure the same thing and return different results almost every time because of electrical noise...

[ebon dew]

Ok just stop. I’m about to go watch a rocket launch. This isn’t good for my anxiety. 🫣

Making me never want to fly again. Something’s are better not known. Ignorance can be bliss.

[violet parcel]

did I mention in Canada we have the weather and bridges are not actually joined together but held by some kind of rubber and glues ?

so sometimes you see actual gaps of 7-8cm across the bridge when walking ?

[ebon dew]

Rivets aren’t a thing in Canada?

Oh well that just sounds like an expansion joint.

[violet parcel]

not enough for canadian weather as bridges can expand/retract by up to 3-4 inches during the year

[ebon dew]

That’s normal for practically all modern bridges.

[violet parcel]

I see, so nothing to worry about eh?

I like to tell the joke when I go over a bridge with friends, remember the bridge was made by the lowest bidder using estimates of newton formulas 😄

but unless it start visibly oscillating or looking like an accordion like the tacoma narrows bridge I wouldn't worry 😄

I find rail bridge much more scary anyway, especially thinking of evacuating the train while it's on such a bridge and the gap between the wood post is like a feet

[blissful roost]

My colleague keeps going to sleep at his desk... So I dropped my keys on my desk.. 😂

Hi, I'm Andre.

I'm looking for a roommate in Sunset Park, Brooklyn to share this lab with.

Here are some of my projects http://www.dubov.ski

Large, furnished living room and kitchen renovated recently.

DM for details - let's build something cool together!

[steel flax]

If using Python you could work with multiple files. The main file would import your code file. Then it can call an init function and a loop function of your code file. Every so many loops you could then call a OTA check function from the main function which would download a new code file, if there is a new version, after which you trigger a reset

Would be more neat to have an OTA system in the UF2 though. Then some library to pass on the connection details to that

[tardy badger]

This isn’t really appropriate for this discord. Not that looking for roommates is bad, it’s just out of scope for this discord. Your projects link is great, if you want to share more specifics there is a #show-and-tell chat and a weekly show and tell on Wednesdays 🙂

[tardy badger]

Matthew Venn who’s behind the Zero To ASIC course is needing tiny asic submissions for a test of TinyTapeOut. Submissions need to be in by Sept 1st. https://tinytapeout.com

It’s really easy, I did it this morning in about an hour 🙂

[rain cradle]

Made this little script to play around with shell, it pulls all the data inside a board using ampy because it already has options for erasing and loading data, but downloading isn't such an easy task

It has a pretty niche use-case (saving code from a board which somehow isn't on your machine yet), but sharing just in case someone might find it useful :)

⚠️ I'm a total noob when it comes to scripting, this will most likely need some tweaks to be compatible with other shells and/or missing some of the commands used. Feel free to share some feedback if you read the code and/or try using it 🤓

[dusty citrus]

is there any Successful IoT Engineer/Developer?

[rain cradle]

Yes, probably millions of them out there

yay for ASIC design 🙂

[violet parcel]

are you going to use the fuel gauge for a battery above 3000ah ? or not single-cell ?

[small elm]

Always going to be single cell <=500mah

[violet parcel]

the chip support a couple of specific capacities not a range and it seem kinda old (not covered by patents anymore)

[ebon dew]

@tardy badger very impressive

[violet parcel]

And we discussed it a few times in circuit python and someone there though it was really bad

if its datasheet doesn't mention charger I would assume it can't

[tardy badger]

it's actually super easy to do if you know enough about digital logic

https://tinytapeout.com

all the instructions there

[ebon dew]

I tried building a simple one in Minecraft once, never finished.

[small elm]

that's unfortunate, I appreciate the info though, thank you

[tardy badger]

you basically get a few different gates, a buffer, inverter, and a d flip-flop. put them in any configuration.

[violet parcel]

I'd like into recent texas instruments battery gauge and see if you can find an example of one being used along with a charger, they shouldn't be that much more expensive than the LC709203F

for me the biggest issue before the rest is that it support 7 specific capacities and I assume it will be the wrong information for values between them

[ebon dew]

Yeah after about 4 it gets confusing. There are people out there like you who can keep track of all the gates. It’s over my head. They always start out with, “this is simple”. No, it’s really not.

[violet parcel]

peoples usually keep track of the resulting binary number or keep a truth table

consider yourself lucky that they don't include logic gate timings 😄 (in real-life going from 0/1 or 1/0 isn't instant, while this occurs the logic gate has the wrong value)

[tardy badger]

truth tables and k maps

anyway, my frequency divider could also be manually driven to be two 4 bit down counters

[violet parcel]

minecraft electric system and computercraft and the consoles in mods is what initially drew me to electronics

Unfortunately my city won't let me cut wood with my punches from the parks 😦

so I'll never be able to open a door from a logic gate IRL 😦

[tardy badger]

I'm trying it out with cascading 8 d flip-flops to give a 2^8 frequency division

super fun. the input frequency basically drives the clock on the first d flip flop, then the Q output drives the clock of the next. and each d flip flop feeds NOT Q back into the D input. effectively halving the clock frequency.

Finished soldering a feather quad board and 2 new S2’s about 2 hours ago. I have a headache now and I can still smell flux fumes with every breath. New hakko soldering iron starts up super fast in like 15 seconds. Used to take my old iron about 3 minutes to get up to temp. It solders way too hot though and don’t think it’s calibrated right.

[tardy badger]

if I inverted the outputs, it would be an 8 bit counter 🙂

[ebon dew]

Yeah everything you just said is Greek to me. I can kind of do pcbs but logic design is beyond me. It’s great you can do such a large array. Path to hw design is in your future. You’re really good at it skerr.

[violet parcel]

the calibrator costs 300$ 😄

guess you'll have to do trial and error

and yes the tip is too small for an IR themometer, I already tried

[ebon dew]

Yeah I saw that. I have enough experience to adjust temp by feel. Don’t need an expensive calibration tool.

[violet parcel]

counters just count event, 8 bits is a fancy way to say it can count from -127 to 127 or 0 to 255 😄

like I used one in minecraft to count my farm animal that would get into my automatic butchering machine

[ebon dew]

The hakko has a different feel to it. Much more efficient for heat transfer. Like you have to solder quick, designed for professionals. Less forgiving of mistakes.

[violet parcel]

poker face

whistles innocently

the one at my local maker space is an old wellsomething and take like 30 minutes

and cant break our own solder because they dont want to contaminate it with lead solder

[ebon dew]

Weller yeah, what I had. Honestly great for beginners to advanced. I think the hakko is a bit higher quality than I actually need. It performs more like a professional level tool. I have to learn how to solder all over again kind of thing, it has a learning curve that I didn’t expect, much different feel to it than my weller and I’m using the same flux and solder that I always do.

[whole jacinth]

Weller irons with electronic temperature control are great, in my experience

[violet parcel]

You haven't even said what moddel of hakko but I already know because I have the same experience 😄

I guess that make my first solders on those LCD even more skillful than I though

[ebon dew]

888D

[violet parcel]

🤣 yeah that's the one

[ebon dew]

The blue and yellow one.

[violet parcel]

wish my oven got heated that fast 😄

[ebon dew]

Maybe part of it is I’m using a super fine tip with it. Maybe too fine.

Didn’t even try the chisel tip. As soon as it arrived I put the fine tip on it, before even turning it on.

[violet parcel]

probably because of me 🤣

[ebon dew]

Oh yeah it heats up like 10x faster than the weller. It’s really impressive and a bit scary.

[violet parcel]

I gave up on these level shifters

seems like very low quality if the SMD resistors fly off when I'm soldering something 10mm away...

[whole jacinth]

maybe you want to try lowering the temperature, or use shorter durations when soldering

[violet parcel]

it doesn't even work if I go lower than 750...

[ebon dew]

I think the hakko is built for speed soldering. Like for an industrial business. I have it set pretty low at 600 and it still seems a bit high. Unsure if I’m too used to a slow iron like weller or if it’s still too hot.

[violet parcel]

doesn't start to melt with the tip on the pad until I'm past 700

[ebon dew]

Oh I can melt at 600 np… and I think that’s the problem.

[whole jacinth]

sounds like not enough tinning or flux. setting the temperature too high will burn off flux quickly and oxidize solder quickly

[ebon dew]

I think it’s like 100 to 150 uncalibrated too high. I can manually recalibrate. Will probably do that this week and look up melt points. Should have done that on day 1.

[violet parcel]

because I it I only apply flux if I messed something up (never before the initial soldering)

otherwise my house turn into a fish smokehouse (I'm the fish)

[blissful roost]

blub

[ebon dew]

Yeah I set it low enough so it doesn’t flash off. It was doing that out of the box set at 750. Flux would go poof and vaporize instantly. Kind of impressive, my weller couldn’t do that even maxed out.

[violet parcel]

wanted to solder my pico the other day but someone posted pics and I didn't want to look like I was trying to upstage them

besides my body needed time to deal with the gaseous lead in my lungs

[blissful roost]

I've still got 2 Pico I need to put headers on.

[ebon dew]

I’ve seen your soldering. I don’t think you have to worry about that yet. 😅

[violet parcel]

pico the one with the shaders-like processing channels right ?

[blissful roost]

My soldering is .. "acceptable".

[ebon dew]

It is yes. Oh was the other job really bad or something?

[violet parcel]

I don't like mine, but it's because of my weimos d0

and those crazy small pins and tight pins holes

[ebon dew]

Oh wrong person nvm.

[violet parcel]

on an LCD or a pico with the large contact pad it's going to look fine

mine looked like those towers in LOTR

Like a micro-saruman could have lived in one of my solder 😦

[blissful roost]

The solder bridges I put on the perfboard are a bit jank, but serviceable. Lol

[ebon dew]

Definitely acceptable

[violet parcel]

my wick is arriving tuesday

[ebon dew]

Perfboard is kind of meant to have bridges though.

[violet parcel]

my only regret is picking up good US/japanese brands so I won't have much to compare 😦

[blissful roost]

Yeah, but I just bridged some jumper leads together.. lol

I can't find my breadboards.

[violet parcel]

I spend like 600$ on electronics so far and lost 40$ to useless parts, too hard to solder or just lost 😦

[ebon dew]

That’s what your supposed to do unless my understanding of prototyping with perfboard is completely wrong.

[blissful roost]

You're quite right, I just didn't want to do it like that.

[violet parcel]

also no circuitpython yet I guess...

I guess I'll leave that channel

[ebon dew]

Solder bridges and jumper wires on perfboard are completely acceptable. Heck even some of adafruits module requires jumper wire like the lora boards.

[violet parcel]

those are voluntary bridges though

[tardy badger]

lol I made a 4 bit memory chunk lol

[ebon dew]

If you want it to work pretty sure you have to.

[tardy badger]

using 2-1 mux as a tri-state buffer because there are none in this simulator

[blissful roost]

I'm looking forward to digging out all my kit..
Hopefully I can build a 3D printer soon, so that will help with my projects.

[ebon dew]

Flip flops with LEDs. Is that really memory though?

[violet parcel]

those are the bridge that DjDevon means I think

[ebon dew]

Yes.

[violet parcel]

when you use leads from resistors/capacitors/exposed wires to connect things (backend) on a proto board to make semi-permanent circuit

[ebon dew]

The sploodge bridges. 😁

[violet parcel]

jumper wires are used to go over the solder bridge as the sleeve prevent them from touching the solder "wires/bridges"

I want to make my 1st one for the pullups for SDA/SCL and the 5V version on the same proto board

possibly with a normal connector and option for a stemma qt one

[neon ocean]

tfw you spend the afternoon doing documentation and BOM management for your hobby project 🙄

[tardy badger]

Wore my other maker hat, chef, this evening

Decided to make up a noodle recipe

And made a red sauce with chicken

[violet parcel]

so I just accidently soldered myself

should I apply flux ? 🤣 😦 😢

red point :(

[whole jacinth]

it doesn't look very bad to me, at least from that photo

[violet parcel]

yeah hurts like a bee sting though, it was almost the 750oF but it was a mm off or something

[violet parcel]

I like the simplicity of noodles, especially the japanese/chinese ones were you just have toasted sesame oil and you almost have a yummy ramen dish with the noodles and oil alone

[tardy badger]

It’s hard to go wrong. Especially when you have semolina flour

[violet parcel]

I mean honestly I just add the shiitake and green onions for common sense, but for me the noodles and oil would be enough

[tardy badger]

Is there a way to interact with these channels without discord? e.g. matrix or irc bridge?

[crystal ore]

Not to my knowledge. I haven't seen any bridge bots interacting here, anyway.

[supple isle]

That's rough.

Discord in chrome on Linux has broken copy and paste.

[blissful roost]

Why Chrome?
Isn't the Discord app stand-alone?

[supple isle]

Because I'm not downloading a discord app. I don't want to.

[blissful roost]

Hummm

[supple isle]

[burnt tendon]

You know, as a kid, I thought rocket science was the coolest thing. I guess as an adult, I realize that it's really pretty much high speed plumbing. Like, sure, your house has a bit of a water hammer problem and you keep having to have the plumber come over to fix the shower valve, but in this case it's a cryogenic valve and if there's a water hammer, the whole rocket asplodes.

[violet parcel]

electronics is kinda like that too except the water goes at between 0.1c and 0.9c

[burnt tendon]

Yeah, but at least electronics has exotic valves in giant arrays. Rockets crash because the propellant sloshed and they couldn't feed it fast enough.

It's a baffling problem, I'm told.

[violet parcel]

then each chip tells you how much pressure they need and the size of the water hose

and some stuff like LEDs need some solid in it because they really like rapids

[violet parcel]

I don't get the joke 😦

But when I was in uni they always made us put units of measures after the numbers because nasa lost a rocket/probe etc because of it

[exotic nebula]

Hi all, can I get a pulse reading on how people back up their (usb drive) circuitpython code? I end up copying code to some other drive (and folder) that is a git repo.
But it feels like I missed the memo on some better way

[tardy badger]

I usually keep a local code.py file for the device I’m working on.

[ebon dew]

I make project folders per board. I have a lot of boards and projects per board. You kind of have to do it by board since there's a lot of board specific code to start with and then your addon-board (featherwings, hats, bonnets) per board.

folder structure would be board>addon board>project

and a duplicate folder of your CIRCUITPY device within the project folder

board>addon board>project name> backup_date

[urban pawn]

and then you put all your projects into a sql db so you can easily search through them right

🙂

[ebon dew]

eventually, probably. i have a feeling when you start accumulating enough completed projects then github will likely become a necessity. i have started using it as a way to easily reference my own code. instead of looking through folders and files i just pull up my own github 😛 is that lazy or smart? unsure. if it works it works.

[late fulcrum]

IMHO, it's often smart to be lazy

[tidal lance]

Anyone ever used a Geiger counter in a project? Or on an airplane?

Was mildly considering building a cyberdeck with o2/co2 sensors and Geiger counters as an artsy end of the world kit.

[sonic prism]

as far as backing up goes, there's a backup command in discotool that I manually run sometimes, it creates backups of all connected boards in a designated folder, not particularly organized or easy to browse, but a safeguard just in case, I otherwise just manually copy back the drive into a local project directory that is usually a git, on dropbox (and then there's Time Machine)

Buying the wrong parts is pretty trivial though.. just stuff 'em in the parts bin.
One day you'll be like.. "I need $thing.. OHH! I have one!"

[violet parcel]

What is the best channel for simple product questions about say this product? https://www.adafruit.com/product/4253

[ancient rivet]

here's fine. if things get more specific / better suited for another channel, can move convo there.

[winter trellis]

Ah ok, my question is that I've noticed that the doubler and tripler featherwings are in "Adafruit Black" while the quads like https://www.adafruit.com/product/4254 or the one linked above are blue. My question is if Adafruit has started making these in black at all as they still are blue as on the product page? (I have a black/gold look to my project so I'd much prefer the black ones)

[ancient rivet]

not sure why they are different colors like that. probably something simple, like maybe different fab houses used for the different runs.

so also not sure if they'll always be blue. later runs may end up being black possibly.

[shadow siren]

I think Adafruit buys a bulk order of the unpopulated PCB's and they have not gone through all the blue pcb's yet and need to reorder in black

[ancient rivet]

i can pass on your question though. it's at least worth the feedback to know that the product cosmetics are important.

[shadow siren]

Who knows next batch might be in pink

[violet parcel]

or IR colored so the color isn't visible to a human eye 😄

[shadow siren]

lol

Remmeber what Henry Ford said, you can have any color as long as it's black

Hi all, just bout my playground blue..
Im in my basic..anyone have reccomendation for learning?

[tardy badger]

History does weird things to our perceptions. For instance, the last Soviet leader, Mikhail Gorbachev died today at the age of 91. I thought he died a while ago.

And I wonder if that perception comes from how Russian history is taught in the US.

[violet parcel]

Or the other way around when you learn someone/something you liked died 2-3 years ago

Like the arecibo observatory died in 2020 😦 the dish fell off

I learned that yesterday from youtube comments from a contact scene 😦

@violet parcel wassup

no today is my rapsberry pi day, still have like 700 pins to solder as well and no acess to a 3d printer to pritn my enclosure until october

[tardy badger]

It’s the math that makes me question being an engineer lol..

[violet parcel]

oh yeah they are hardcore

but for me it was the mountains of homework

that destroyed me

Didn't know how an engine worked, especially the parts in it like the pistons etc

[tardy badger]

I mean, I already have a Bachelors in Computer Engineering (Electrical Engineering + Comp Sci). I'm working on a masters degree in Electrical Engineering

[violet parcel]

and I was supposed to find all the forces that applied in the engine, 80 questions like that for next week

[tardy badger]

mechanical engineers can have that

[violet parcel]

still confused to this day why I had a basic material science course with electrical engineers in the same class

not sure how knowing the different types of concrete and how they rupture help electronics...

[tardy badger]

electrical engineers need statics/dynamics, and materials science as a pre-requisite.

my Introduction to Solid State Electronics class is basically a materials science class.

[violet parcel]

that said I saw capacitors made up of polyester today on amazon which was very weird to me

[crystal ore]

I presume that's the dielectric material between the conductive surfaces.

[violet parcel]

yes but isn't it a kind of textile ? and don't they put acid in it ? acid on a polyester shirt sounds like a bad idea so not sure why it's fine here

[whole jacinth]

polyester is a polymer. it's sometimes formed into fibers that are woven into textiles, but it is also available in other forms

[whole jacinth]

do you have details about the acid you mention?

[violet parcel]

the one they put in all capacitors, years ago when I did a lab I was told that all capacitors had acid in them possibly HSO4 (sulfuric acid)

and that it could explode/splash on us if we poured too much voltage into it

[whole jacinth]

that's not universally true. there are many kinds of capacitors; not all of them contain acid

[whole jacinth]

aluminum electrolytics with non-solid electrolyte seem to use boric acid https://en.wikipedia.org/wiki/Aluminum_electrolytic_capacitor which is typically a weak acid. don't believe everything you're told in school without cross-checking

i think non-electrolytic capacitors don't have a reason to contain any acid

[whole jacinth]

air and vacuum capacitors trivially lack any acid. so "all capacitors" was an overgeneralization

[tardy badger]

Only in stem field education can 5 problems kick your brain down a flight of stairs

[whole jacinth]

polyester capacitors are usually metallized film or film/foil construction, and non-electrolytic, so not a polyester textile https://en.wikipedia.org/wiki/Film_capacitor

[rapid geode]

Are we still talking about the irrational fear of capacitors?

[burnt tendon]

It's a polarizing issue sometimes, I know.

[crystal ore]

Yeah, but that kind of extreme fear can be tantalum to a mental illness.

[vestal rain]

Not sure if this is the best channel to talk about this but not sure where else to bring this up. I recently ordered two QT Py RP2040s and these are the header pins that came with them. The long one was in one package and the three short ones were in the other package. None of them have the right number of pins for the QT Py. It's not a big deal for me since I use other header pins but it might be a problem for someone else.

[whole jacinth]

the long ones are meant to be cut down to size. the shorter ones look like they might not have enough pins, so that's probably worth emailing support about, in case you want replacements, or maybe a QA issue with the product packaging

[ancient rivet]

i think in general, they're just making sure you have enough total pins

2 x 7 for the qt py. so 14 total.

some trimming etc. may be required

[whole jacinth]

yeah, i can see that. having to assemble a row of headers out of two pieces isn't necessarily great in terms of alignment, but probably workable in most cases

[ancient rivet]

yah. not ideal. but works OK using a breadboard to pre-stage the headers. then plop the board down on those and solder.

[vestal rain]

The long one is totally fine with me, they're easy enough to break apart if I was using them. The main issue would be the short ones. If each section was seven or more pins I wouldn't have said anything about it. Soldering short sections of pins is a pain and may be an issue for some people.

[ancient rivet]

(i've got an old breadboard i dedicate to that)

[vestal rain]

Same. Again, not a problem for me but may be an issue for someone else down the road.

[whole jacinth]

and you might have to file down the adjacent spacers to fit when assembling a row out of two short sections

[shadow siren]

nah you just break the pin headers to a size as needed

also if you do this a lot just go get a pack of long ones so you have a stock of pin headers

[whole jacinth]

Adafruit is usually good about giving you more total pins than you need for a given board, so i've got lots of small header strips from trimming down the longer ones

[shadow siren]

ditto and I simply went to Ali-express and got a couple of 20 packs of 2.54 pitch headers that are like 50 pins long and I break as needed

Hey folks, I'm wondering if anyone has recommendations on LED strips for under cabinet lighting. Doesn't have to necessarily be programmable, but I can't find out how to navigate all the various LED strips that are available so that I can find a nice dimmable warm white for my kitchen. I figured Adafruit community would be the most opinionated!

Maybe try a DotStar strip if you're willing to program it

I feel like an Trinket or Arduino Micro would work well
