.... Does a not drunk Canadian actually exist?!?
i never said canadian
I assumed a typo, didn't I?!? Lol
learn yer cultures n stuff! 😛
yeah cause you stole ours
empire, pft. all that island is good for is being repeatedly conquered
sure, they were conquered by eton college
We did have this thing... "EEWWW", I think they called it..
Didn't last.
It's dead, Jim
im trying to script a batch exporter in fusion
Sounds like fun.
I have to sit and watch monitors until 7am.. #fun.
Could have no job.
haha
Plus YT, if I'm stuck for anything else.
i dont have a tv. need to get one at some point.
like so
seems expensive
haha
when are 100" roll up tv's going to be $50?
I'm still using a 32" 1080p at home, after my 42" got smashed.
doh
Cheap projector onto a distant wall
projectors are meh
and there are no distant walls in my house. its too tiny
Same
this room is 12x14 ft roughly. the tv in the render is 85"
I have a tiny LED projector and I love it for travel movies
I have to physically tilt the unit even at the max keystone angle because the wall is 10 ft away
The apple ar headset will be the next step in productivity
SoonTM
Uuuugggggghhhhhhhhhhh
Apple AR will change the world
ar.... no thanks
Lmao
Yes, they will totally change my "Do not give money to Apple" policy. 🤣
the future is 2040: cars have achieved self driving, all displays have been made obsolete by ar, you still aren't allowed to work from home
I can't do WFH... policy not permitted.
everything in my industry is wfh at this point
it was a pain at first, but we all got used to it. we can have a smaller studio and still have 100 people cause they dont all need desks
I'd love to WFH, but I'd have to get a role which permits it.
I really want to get back to Linux SysAdmin.
I'm thinking I could go for a CKA cert.
At least that would keep me local, with this company.
I was at 60% WFH. Work clawed back til I'm now at 20%
i need to take everything out of my livingroom to do the hardwood, drywall, paint, etc. but my house is so small i have nowhere to put the stuff
I type out “zee” and I think of all the places that say “z” as zed and I say “zed-ee” and chuckle
Just use your front lawn
I know, and that’s why it’s funny
my front lawn is covered in snow
if it was warm i would put it on the patio covered in plastic
Just put a tarp down, it’ll be fine 🙂
Jokes aside, I also have a small living space.
But I lease so no renovations for me
asa finished house, its perfectly fine. but to renovate, its so awkward
how do you renovate a bathroom when you need the bathroom?
ha
answer, you make a temporaty second bathroom in the corner of the kitchen
then you have to remove that later..
etc etc
but now im stuck. i have a stack of plywood and drywall and the hardwood flooring boxes. whihc i keep having to move around
ponderrs
Invoice phishing scams are interesting
Especially when the come from imaginary companies in countries I never did business lol
sends spam email to trash
Then they try to send follow up emails like “hey thanks for the invoice”
Sometimes I think about using all these tactics I’ve learned that people use to make money… but then I feel sick and stop thinking about it
In this case, it’s not an imaginary company but someone phish as Mainstream New Zealand Ltd.
If someone did a lot of overseas shipping they might pause for thought
But I’ve never used the company nor am I doing any international shipping other than getting stuff from aliexpress and JLCPCB
The only international stuff I usually get is eBay
And my plush waifu from China
Lol
Yeah
Anyway, I get good exposure to random phishing schemes hoping to compromise companies.
Yeah, you have to be so careful doing that. Hats off to them for deleting all their servers lol
I saw one where they locked out all the computers in the scam call center and the employees just started pacing and throwing keyboards
Very satisfying
Hehehehe, yeah… I wanna do that
I was just reading through my logs from a pair of Steam account scammers.
Funny AF.
I got both accounts banned from Discord. Lol
lol
some years ago around here there was a ponzi scheme called sixthcontent, you could make good money by making thousands of accounts, then even when they exit scammed, I just chargebacked; like you could get an amazon giftcard of 25 euros for just 12.5 euros, pretty surprising the amount of people who though that all of that was legit lol
I used to work for a company whose accounting department was such chaos that I'm sure they paid every invoice they got because they didn't have any kind of tracking.
The parent company of my current employer is almost like that too - they found out someone was colluding with contractors, fired him, cut off contract which caused a chain reaction of subcontractor bankruptcies putting 500+ people out of work.
lol
500+ people out of work doesn’t sound so funny…
People shouldn't commit fraud
At the school I’m currently placed at, they have new folks in the business office, and they’re digging into stuff that had piled up from the last business manager and his counterpart who basically did the bare minimum… and they’re finding a lot of things we’re just filed as “miscellaneous” and paid on the credit card that maybe should have actually been investigated or challenged…
The people in the subcontractor companies may not have been aware that their bosses were committing fraud
What I mean is the people committing fraud should have considered their choices
Yeah. It’s funny when one jerk gets canned and ruins themselves because they were doing fraud, not funny when that cascades to impact innocent people
Not on the same level as fraud, but... A couple of our contractors caused a major outage last week.
I'm expecting their contracts won't be retained.
I certainly hope not.
Personally, I think if someone does something like commit fraud, and that leads to the company they work for going bankrupt and innocent people lose their livelihoods, the perpetrator should be held responsible for both the fraud and financial hardship of those innocent people
Completely agree
Put them in the stockade and pelt them with rotten fruit!
Also make them pay every spare penny to those folks. No nice things for them. 25¢ Ramen and a cot.
Consequences for financial and corporate crimes are not severe enough, they're often just a cost of doing business. We have life in prison for humans, what about life without income for corporations if the misdeed warrants it?
"oh, we got breached? lol, here have some free credit monitoring"
Yeah… companies should be penalized more. Also the execs should take personal responsibility when they do horribly dumb things
Here’s $5.12
yeah, class action settlements are a joke
I got a rock
Class action is great.. for settlement lawyers who get huge paydays
Just go to law school for representing class action suits and you’ll make good money
Mostly because they never go to trial and most companies are okay settling for multi million dollar sums for what they view as an oopsy
it is a way to pursue wrongs when individuals can't do it themselves, but it's not enough
Part of me wants to do that… and then give 99% of the money away
It should be reformed so lawyers don’t do it for huge paydays which skiff consumers actually harmed
Yeah, most of the money should go to the harmed parties
My information was leaked as part of the breach, and they wanted me to trust Equifax with monitoring my credit? No thanks..
Yeah…
The lawyers walked away with tens of millions and I got.. $5.20; others were forced to take the credit monitoring
It’s just not right
I did get a notification about the Apple butterfly keyboard settlement
I wasn’t a class member if that suit though
Wait, there was a settlement for that? I didn’t know that… I have a 2020 MacBook Pro, which was impacted, and they replaced it despite being out of warranty, free of charge (which actually included a new battery! Apparently that’s part of the top and can’t be replaced by itself… wasteful, but bonus for me)
Yeah, you can get up to like $300 for a single replacement claim, $500 for two replacements?
Claim period might still be open too
I was fortunate and my mid 2017 mac hasn’t had issues with the keyboard
Hmmm... Do you need to be first hand owner? I got it second hand
I bought mine new but it’s been heavily used for 5 years
Sounds like you got lucky, like how I got lucky with my Switch that I got in 2017 and haven't had JoyCon drift yet, lol
Altho I haven't played it heavily...
My switch mostly collects dust despite me wanting to beat Pokémon scarlet and violet
lmao
I’ve played a little but my depression swings either wanting to play games or bury myself in electronics projects.
Or sitting on the couch playing a phone game solving jigsaw puzzles
My depression typically has me either trying to sleep or watching videos and playing puzzle phone games or walking...
i have a depression in the lawn where i shovelled a hole
Lucky you only have that
Presumably to put a tarp down for your furniture 😆
On the note of depression, I love that my brain can vividly imagine things in vast 3D spaces and just conjure up anything. I definitely think that activity leads to depression when there are things in your mind that are from the real world that can not be so easily manipulated if at all.
It’s a balancing act for sure
I do love that at least one of my outlets is making things
All the art I can create in my head, but can't get out to share...
I can feel constructive and try to pump some serotonin into my body.
Same.. I wish I had the drive to paint
But I start and I just don’t know how to actually make it look how I imagine it
Unfortunately, while I might have the drive, I don't have the ability...
Shame I can't paint my apartment... Something not boring off-white would be nice.
My town home came with gray walls and white trim which was nice
But now most of my furniture looks weird because I bought gray tones to contrast white walls in my apartment
When I eventually move to the US, my mancave will be black and red.
Drive, ability.. both issues for me
I can freehand drawings based on what I see visually. And have some shapes/characters memorized
But painting is a who other story
Bold colors
😁
Lots of RGB too?
No RGB at all.
Not even to trim the ceiling?
Correct
A bunny run going around the perimeter of the room?
"Mancave".
No buns allowed.
I can't do that DX
Man caves are an interesting concept to me
I just want an office with my stuff that I find comfort in
Ah lol
I rarely ever drink so maybe just a soda stream for me lol
Or a kettle and good assortment of hot cocoa
Maybe some teas
Earl Grey is a must.
My Pokémon stuff too on shelves
An adjustable height desk would be fantastic
We have some motorised desks at work.
Not my thing, but cool.
I want enough space for a 6x monitor mount, 2x3 arrangement.
I managed to mess up my back sleeping early December, being able to stand while I work would be nice
I need a new back
Same
I want less sciatica. Lol
It’s like I turned 30 and my back was like “right, that’s about enough of this” and threw itself out and compressed a disk or something
I also get this odd numbness between my shoulder blades.. very odd.
Be sure to read the “right, that’s about enough of this” in an Australian accent
I can feel my liver and it itches
I have sympathy feelings which is why I could never become a doctor. Your liver itching makes my body physically cringe lol
Now my livers itching
... I shouldn't tell you the rest, huh
Did you know.. French fries didn't come from France...
They were cooked in Greece first.
😁
I should start charging fines for stuff like that :P
I'll send cookies... When I start making them again.
Did you British call fries crisps because they’re usually crispy.
I call fries fries.
Welcome to America
Fries = skinny.
Chips = thick.
What about steak fries?
tavern ;)
Thick = chips.
i've been missing the microsd bff all my life and i never knew it
Except chips are very very thin and sold in crinkly bags
Steak FRIES
Yeahno. Lol
There’s a restaurant in a tiny town in Wyoming called pitchfork fondue that cooks steaks in hot oil and cools the oil down by making potato chips
It's so neat. I'm already trying to think of other ways to spend money on adafruit gear to use it. Nice job ladyada! Very sneaky.
They also have fruit salad, regular salad, and dessert lol
Steak chips
Tis delicious
I knew the owners, they were very nice people
They sold it a few years back
in the ...forever i've been here that was the first message i've sent in general (aside from #pet-photos because it's #pet-photos)
i actually have a project planned that the microsd bff will help a ton
Same!
I’m going to stack the TFT BFF I made with the microSD BFF, and a LiPo power pack I made two years ago
Add a 150mA battery and an esp32-s2 qt py, print a small case and have a pager that delivers memes instead of emergencies
Like that?
Correct
YOU CAN STACK BFF BOARDS?
That sounds like an intimate question.....
Steak fries
Dem's chips, innit.
my brain has expanded
And make sure the BFFs don’t have any conflicting pins of course
Stack 20 microSD BFFs, lol
Just get the extra tall headers
Quick, what can I use to improvise a tab for a battery compartment?
you theoretically could stack 11 without conflicts
glue?
Glue is permanent and non-conductive, lol
typically non-conductive anyway
what part do you need fixed?
ohhh i thought you were talking about one of the battery cover tabs
lol, battery compartment is made of cardboard
Anyway, I’m gonna walk around; hit a button on my phone and the pager goes off “oops, looks like I missed my appointment! Better run!” But in reality it’s a meme
lmao, ttyl
more cardboard then
Cardboard is non-conductive XD
add solder
Cardboard + solder = minimally burnt cardboard, possibly a fire, lol
My gif is my idea, foil 🫣
use the same thing they use to solder THT where they dip the pins in a pool of melted solder to dip the cardboard and voila
Hmm... but can I solder copper to aluminimum? And don't I have to worry about galvanic corrosion?
You act like you don't need to keep warm and I just don't understand
It's 85F in here already!
bring a fire extinguisher
Having ash for a battery compartment isn't gonna work out XD
Not with copper foil
dip a lamp mantle in solder and cut it up?
i have a hook on my wall SPECIFICALLY for kapton tape
that stuff holds the electrical industry together
Kapton tape is on my mic arm because I use that a lot... copper tape not as much

uh oh (shortened for discord)
Copper tape is great for doing touch devices
I did get a touch cap shield I might use it for… not sure why I bought that XD
The tape or touch cap shield?
Touch cap shield. Got the tape for various projects, but largely to be bus bars inside enclosures and such instead of wires
Ah makes sense
Question is… where the heck is all the copper tape
hammerspace
I got 3 different sizes, the smaller sizes had 2 rolls, and I found only the unopened medium roll DX
Oh no
ATLA better than TLOK
The copper tape
i forgot about the cu tape for a sec (typing hard in dark(with onw hand))
Lol
You need practice
cmon
i have (satisfactory(i got the game 2 days ago and have already logged ...checks steam 21hrs))
The “typing in the dark with one hand” game? Lol
i have a light-up keyboard it's just too bright
…… wait, why are you typing with one hand? Are you eating Cheetos at your computer? DON’T GET CRUMBS IN YOUR KEYBOARD
(you try doing a keyboard swap on a laptop)
mouse
i ain't eating cheetos in bed i ain't wanna be murdered by me mum
Lol
i need the mouse to point and also so i can see the screen well
Hot take: I like both ATLA and TLOL because they are both good shows that stand on their own
I want eyetracking tech to replace the mouse, one where you double blink to left click
also i got clear aligners so no
This is the correct take
I am confuse
YES but TLOK is worse (to me) because one of the things that made ATLA so good was that there was no technology (at least no modern tech) so it was interesting to see how they got around that
lying down in bed
I don’t want this because I double blink instinctively sometimes and sometimes my focus point isn’t where I want to click
I don’t think the fact they didn’t retred the same ground makes it worse. They tackled a new era — where Bending battled technology
Why can’t you take your hand off the mouse to type?
i can go cross-eyed on command and that eye tracking would be a HUGE pain from me just stopping to think for a sec and then the mouse has a seizure
i would fall flat making it 1: harder to see the screen and 2:neck get sore
yoink
I am further confused....
me no can move arm
I can't imagine how you're laying that you'd not be able to move your arm
ON MY SIDE

sigh
... where do you have the mouse
it's hard to explain without a photo
I'm imagining you to be all contorted in painful ways
the way i'm lying is my back is close to the wall i have the laptop resting on one of my legs and the mouse goes in between the laptop and my pillow
actually it's quite comfortable
this all started because i made a typo
Strange XD
this is impossible
It is with that attitude... whatever it is
?
I dunno what you're saying is impossible XD
impossible to explain over text
oop
https://adafru.it/1660 there a KiCAD footprint/symbol for this?
there's an EagleCAD library for it, but I'm not 100% sure if/how you'd do that in KiCAD
There's an import function for KiCAD for EAGLE components
you can (i have) import the eagle lib in kicad but then all of the pin names are messed up so without modification you can't use the footprints
oof
it is pain
wrong gif
eh?
GIFs are considered links, and Dyno doesn't like when you post them in rapid succession. Even tho you deleted one, it counts against you
Not sure what the cooldown is
i was just about to ask what's the cooldown
Mods might know if they're watching
mods are always watching
lol
you pretty much always have to be watching to stop minor uprisings
The unbearable weight of knowing you will never able to manufacture silicon ics on your own from silicon dioxide precursors to the final packaged product
the pain
You can make your own silicon at home
it probably won't be chip fab quality but it will be "silicon"
Well, it'll be like 1970s-1980s fab quality
probably closer to late 60s early 70s
I'd be okay with z80 or 6502 spec ics
you can still get 6502s
Be this kid http://sam.zeloof.xyz/category/semiconductor/
i've seen that before
i wonder if there's a Z3
nope
he hasn't uploaded to yt in a year
He's doing 10 micrometer, but I know a lot of earlier stuff is like 100+ micrometer, so much easier
I wonder how pure your silicon needs to be for the really old stuff
THAT is a good question
Hey Adafruit, inhouse silicon when? https://twitter.com/szeloof/status/1549937044067172352?s=20&t=Cu4GIzv_qAECMZGitHO0RA
hmmm the copyright on sam's page says 2018 and their brother's (adam) says 2023
when cows fly
Lol
Sam was active on Twitter as recently as December 23, 2022, so just not updated copyright
oooo
I mean, they might do it one day. Not soon, because LadyAda and PT said as much on Ask an Engineer recently, but it might happen eventually, especially if they keep growing
if Adafruit developed their own silicon, I’d guess it would be RISC-V and be a circuitpython first device
thatd be awesome
it was more of a reference to hilda (a good show on netflix GO WATCH IT RIGHT NOW) than an actual date
Lol. I started watching that, it's super cute... must continue
i do hope adafruit grows enough that they can make custom chips in-house (doesn't even have to be in-house i just wanna see some chips with the adafruit logo)
It’s very possible. Adafruit could probably easily pull it off too. There’s quite a few people I’ve found connected or near Adafruit who would be able to make it a reality.
there should be a 3rd season but we haven't heard any news recently
But like a 3-5 year reality
Fabless semiconductor companies are the norm these days.
Lots of capacity opening up on older processes too.
28nm go brrrrr
sadly my favorite character (raven) doesn't appear in s2 and is replaced with a white woff (they actually had a scene where he said he had to go and would be back next year (or s3) for the next raven festival)
welp what i said isn't big spoilers
cancel life and start watching hilda again
don't watch the movie (hilda and the mountain king(that has a FANTASTIC intro sequence)) until you finish s2 because the movie starts at literally the second the last episode of s2 ended at
it's only 10:44 pm
It’s 23:45 here
i forgot the pm
have you seen trollhunters?
watch it
gn
the whole tales of arcadia series is worth watching (trollhunters, 3below, wizards, and the movie trollhunters rise of the titans) in that order (it's the canonical order and if you do it any other way you will have both big spoilers and huge holes in the lore)
gn mods imma sleep
The school district my kids are part of was the victims of a data breach yesterday. Thankfully they didn’t wait till weeks later to admit it.
What a wild world we live in that people go after schools.. the information of children. Truly shameful.
And hospitals…
Yeah..
stupid guys... someone looking for me? :p
Are you a bad one? If not, you’re safe :P
my university is just straight up dumb, they claim about security and whatever, but then group chats are public, you can get personal informations such as name, mails, numbers, classes and eccetera for both students and teachers, then if you start looking for each individual socials, there's more informations that you can freerly obtain ; I'm sorry but this is ridicolous
also their website is pure trash
but looking for other local universities, it seems to be a common occorrance
but somehow all what scammers could think about is about using the contacts to sell fake books
All it'll take is a good hefty lawsuit when a data breach happens, and they should get the message. Although it's absolutely amazing, and scary, the number of people that just don't understand security.
I had to create an account on a website to allow my doctor to access the info from my new insulin pump. So I throw one of my standard random 24 character passwords at it from my password manager, and it rejects it. Finally figured they had an upper limit of 20 characters on password length. Which to me is truly frightening. There should not be any reasonable upper limit on password length, because you're going to hash it before storage, and that fixes the length of the database field. Upper limit of 1024 characters maybe for the input field, because I can't see anyone hitting that, and it's just an in-memory buffer, so it's free.
Non-security people making systems that are inherently insecure always pains me
Yeahhhh
Be the data breach that forces their hand
what I find most ridicolous is that they are supposed to teach, when their own products suck, I really despise them, they are just like taxies, a lobby that you can't get rid off
Just got this little cute small thing
I know this isnt the right way to make an SMPS, but theres something so alluring about using the analog parts of a microcontroller to make an buck converter
Price wise its either on par or slightly more expensive than using a dedicated buck IC

New tutorials on the Adafruit Learning System: ht...
I'm looking at using a ds2413 but have a question about 1wire pins
https://learn.adafruit.com/adafruit-1-wire-gpio-breakout-ds2413/onewire-library
Per the documentation, you set a pin as a onewire pin with OneWire name(pinnumber)
But, how do you unset it? Like, if you want to use that pin as a gpio?
The library doesn't seem to have anything like a deinit() call, but it doesn't really do anything special, you can just start using the pin yourself and call pinMode() and so forth on it, I don't think it would be a problem. If you want to shift back to using OneWire, you'd just call the OneWire begin() function again.
My understanding is that there is no activity on the 1-wire bus unless I ask devices to talk, right
and the library wouldn't randomly chatter to devices
so as long as I'm not explicitly doing 1-wire requests at the same time, there should be no issue?
That's my guess. I don't know if devices might try to communicate asynchronously, but I don't think they do.
funky
Granted, if you have 1-wire devices hooked to it, and start signalling, the devices could get confused and try to respond
Here's the actual context
I have a connector for peripherals
ground, tx/rx, and an ADC to detect which kind of peripheral I have attached using resistors
I'd like to be able to repurpose the rx pin as my onewire pin
as, theoretically, I'd want to pull it high so it's not floating when nothing is attached. I can use that pullup as my onewire parasitic power pullup
so basically - if a certain peripheral is detected, use tx/rx pins as serial. If another is detected, use rx pin for onewire
Seem doable?
And you'd switch peripherals while powered (hot switching)?
It seems to me like it should be possible to make it work, you'd need some smarts to detect when the peripheral had been switched and keep track of things and avoid bus contention but it seems doable.
the other peripheral is a couple of relays controlled by a DS2413
I might use TX for OneWire (so it's still an output pin)
one peripheral shorts the ADC(pulled up to 3.3v normally) to ground, the other peripheral pulls the adc to 1.5v, so I can detect unplugged and each device
So full volts means nothing's connected?
exactly
problem is, I need to pull it high to power the onewire devices
and I'm not sure thats a good idea
Serial TX normally idles high anyway
yea - which is why I was thinking I should pull rx up, because it would otherwise be floating if nothing is connected to it. rx high = idle
I really don't know which is better though.
Ah, that makes sense, and avoids having a tug-of-war
Wouldn't rx be unused when in OneWire mode. tx idles high in both serial and onewire mode and the detect pin knows what mode to put it in
rx would be the onewire pin as it needs to be pulled high for power
i mean, either would work
but pulling tx high seems like not a great idea?
I mean I guess either way, a tx line is being pulled high from someone's perspective
if I plug a serial device in, my pullup on the rx side is now on the tx side of the other device?
🤦♀️ idek at this point lol 😢
That's what I'm saying. tx pulled high is normal operation for both protocols
but if nothing is plugged in, my rx is floating
two birds with one stone - stop the pin from floating and power my onewire stuff
It can float while it's unused. Isn't that the point of one wire stuff that the data pin provides parasitic power?
My (very limited) understanding is that floating pins = bad
but I guess it doesn't matter if I'm in "discovery" waiting for a device to connect
While pulling TX high would be harmless, driving OneWire high could cause bus contention, so I now agree with your choice of RX
Onewire is expecting the pin pulled up till it transmits though
There is no chance that a onewire and serial device could be connected at the same time, to be clear
Yeah it doesn't matter for an "unused" pin to float and it'll be effectively unused while in 1-wire mode
Sorry what do you mean by bus contention?
When one device attempts to drive a signal high at the same time another device attempts to drive the same signal low, you get a tug-of-war that can cause large current flow and possible damage.
This is why, now that you explained it, I think RX is a better choice to do double duty as OneWire
Looks like I got it right.
I see
So if my tx pin is driven high by the board, I might kill a onewire device if it happens to be connected (bug in the code or something)
but the rx pin will never be driven high ever in serial mode
Yes, that's my thinking
i seee. interesting!
Adafruit recommends 4.7k for the 1-wire pullup. Is it possible that could cause issues for serial?
Usually pullups are much larger I think?
like 10-20k etc
The 1-wire bus is expected to be pulled up there's no risk there
Yeah but I mean - when in serial mode
For 5V logic, that will draw a little over 1mA, which shouldn't cause problems
Then it would draw less than 1mA
Basically, 3.3V divided by 4700Ω
interesting.
Yeah should be able to sink and pull that down no problem
Thanks for the help all :)
can you stack BFFs on top of an esp32-s2 qt-py? (https://adafru.it/5348)
As far as I know, you should be able to use any BFF with any QT Py
no i mean the images show the bff going on the bottom i'm wondering if the bff can go on the top side of the board (the side with the usb port)
Oh, if you’re using pins for spacing, sure, just gotta make sure you have it in the right orientation
Like, the side that would be pressed against the QT Py would be up if it’s on top
yeah
Hi, currently working on a project with a RP2040 chip at the center of it
Designed the PCB and got it printed, it is a fully remote controllable 144/440MHz ham radio transceiver
Waiting on the main vhf/uhf modules to arrive, for now I am working on the software, struggling with getting SPI communication between the rp2040 and the data link chip working.
If anyone has experience with micropython or just rp2040 programming in general I'd really appreciate it if you could DM me to help with getting this working
i have a rlly dumb question (bare with me im jus startin to learn this stuff) but ok so i was toying with pico project and i got advice from another member here that the reason stuff wasnt working was because my pins werent soldered so i did that and stuff started (kinda)working
//had some wrong parts//
but i am curious what the difference is between the jumper wires and the pin headers, why do pin headers need solder but jumper wires do not?
how do u program your mcu through which software environment?
anyone here uses mplab x ide?
So I am trying to add external codebase in mplab x environment anyone knows how to add it? I am generating code thr mplab harmony mcc so files get generated automatically?
If you’re working on a breadboard, anything stuck into the board itself gets squeezed inside by little spring fingers, which gives a good, mechanical contact. When you lay a board on top of rows of headers, there isn’t really any pressure so you don’t get that firm connection
yes
You need a PICkit to program PICs and I think AVRs too
Harmony should be integrated into mplabx. Use the plug in feature
Are you supposed to leave the reset pin floating?
aww, penguins are so cute!
Yeah, they sent me pictures and a video of a penguin waddling along
cooo
the penguins at the zoo here are super fun. They'll hangout by the window and interact with you.
Share!
Fancy far away fren
not animals but the scenes where i was was nice
you see the snow covered ice what is the lake
omg so cute! that's awesome 🙂
thank u that makes sense 🙂
Punxsutawney Phil: says 6 more weeks of winter
Me: checks the calendar yeah sounds about right. 6ish weeks till the spring equinox
It means tonight you'll be visited by three spirits: The Spirit of Groundhog Day Past, the Spirit of Groundhog Day Present, and the Spirit of Groundhog Day Yet to Come.
They’ll bring a new groundhog
Worse, Napoleon will return
6 weeks of frogs
well, it is quebec....
no
I haven’t seen it yet
It’s an oldie but goodie
Can anyone recommend a good website that can do accurate 3d printing at a decent price?
Even better if it's a site that can cut acrylic. I found a site that can do that, but the price is crazy for two pieces.
the pricer is always crazy for small things
shapeways is not bad usually. pcbway has cheaper prices if you do more volume - 10+ pieces i think
I usually have my acrylic cut at Pololu or SendCutSend. I hear OSHPark offers cutting services as well. I don't know as much about 3D printing services, other than they exist. However, you might want to quantify what you're looking for regarding accuracy and price, and possibly related factors like size, complexity, material, etc.
@late fulcrum Question for you related to what you helped me with yesterday - I could just, use i2c for everything and not need to bother switching back and forth
Is i2c suitable for that kind of thing? intra-device connection?
I think most of the time it's used between ics on the same board, right?
I can use an MCP23008 instead of the onewire switch and just speak to the other device over i2c, no reconfiguration junk needed
You're right, it's designed for short distances, but if your wires don't go too far, it might be a neat overall approach.
How short is short?
🤔 at the slow/standard speeds it seems that I should be able to get meters
About 1 meter, as far as I understand it. That said, there's a breakout we have that can extend that length. https://www.adafruit.com/product/4756
I don't see a clear answer on how far it extends it though.
maybe related I don't care about speed at all
so dropping speed to get more distance is totally good by me
I think it can also affect data integrity. You'll want to ensure that's not the case.
But yes, that might be an option.
hmm
Madbodger would know more than I do. 🙂 I knew about the extender and thought I would mention it.
If only I could communicate mcu-to-mcu with onewire lol
there are adapters that run I2C over ethernet wire, can get to 75-100 feet
(Many others would know more than I do on this.)
It seems like there should be an easier way of doing something like this
Feels like I'm XY problem-ing a little bit
You might be able to use onewire like that (I think there's a target implementation). Or you could use ordinary asynchronous serial (which you already have) with a simple protocol. Or these I2C extenders https://www.sparkfun.com/products/16988
You can often enable simple parity checking, but if I'm really looking for reliable transmission, I'll use the common approach of something like a simple CRC check.
gotcha. but that would be handled by your code
You'll see that used in things like hex files for sending binary data to burn into ROMs or microcontrollers.
I don't think I2C has built-in error checking either
And there's no such thing as a serial io expander 🤔
Output is easy: connect your TX lead to several RX inputs. The other way is the tricky one.
This seems harder than serial to 1-wire, but could I switch between serial and i2c?
both are usually implemented in hardware afaik
whereas 1wire is bitbanged
Perhaps, but you run into the same sorts of gotchas: if the two ends got out of sync somehow, you could end up with one in TX mode trying to drive a lead high and one in I2C mode trying to drive it low at the same time.
There are soft serial and soft I2C implementations too, which are handy if you run out of hardware ports and want more.
Heh, I was thinking the same thing. I was even looking at the schematic of the TCA9548 I2C multiplexer chip to see if it could be used to switch asynchronous serial signals instead of I2C. Weirdly, it looks like it could (it's basically a MOSFET bus switch), but since its control input is I2C and is also tied to the multiplexer inputs, it wouldn't work well that way. If the multiplexer inputs were on separate pins, it might, which makes me wonder if there's a variant of the chip like that, or if there's a multiplexer chip that would do what you're looking for.
Here's the overall problem bc idk if I've really communicated it well
I'm building a device. The device can be connected to two peripherals
Peripheral 1 is another MCU, I need to be able to respond to requests for information from the other side and send information, error states, etc over unprompted as well.
Peripheral 2 is a bunch of relays. 2 minimum, but I'd like to be able to control as many as four. I'm using one of these bog standard relay boards. 5v input, each "input" pin is pulled low to enable that relay.
I need to be able to tell which peripheral is connected without power - optimally a resistor-based identification system of some kind
I assume by "without power", you mean the peripheral is connected but not powered? Measuring a resistor without any power would be problematic.
Currently I plan on doing detection via a gnd pin and adc pulled up to 5v. If I short the adc and gnd, I read 0v and know I am plugged in to peripheral 1. If I read 2.5v I know I am plugged in to periphreal 2. 5v = no connection.
Yes.
I think if I just add a 5v supply to the 2nd peripheral I can connect their grounds and use my two serial pins as pulldowns for relays - but I only get two relays that way, and I can't use the optoisolators on the relay board. Theoretically that is enough but if there is an easy way to control four, that would be great
You could use SPI for both (a GPIO expander or shift register for the relays, or SPI target hardware/software for the MCU), or I2C (there are I2C GPIO expanders as well) like we were discussing previously
maybe you could have an input pin on the "brain" device which is pulled low on one peripheral and high on the second one (assuming they get power over the wire connecting them to the main chip and not only data)
Wait, so is this a device that sits between primary controller and relay board, or a device with the capability to connect to either or, exclusively with the same port?
One device with one peripheral port that can be connected to one of two peripherals at a time.
Isn’t this target dependent?
I thought some spi devices use CS as a trigger to stop idling
Those devices, you'd simply wire CS to be always asserted
I think it's usually active low, so I'd probably just ground it.
... respond to requests for information ...
since one of the posible peripherals is another MCU to which you can talk... wouldn't it be easier to send a SPI message to check if the MCU is there?
i dont really understand why you need a "without power" way of identifying, you'd only need to know what is connected once the main MCU is about to work, and at that point you'll mostly want the second one (if using that peripheral) to be running too
Because this device is a battery
Oh right, yeah CS is usually active low.
I'm checking to see if the device at the other end is a charger or is asking for power
The device in question has no power until I can confirm that the cable is fully seated and that the cable is plugged in to something asking for power, safety feature
This also lets me kill power immediately if the cable is unplugged
The relays/peripheral 2 is a charger, big cc/cv power supply and a bunch of fans that I'd like to be able to control. Can disable charge current until I confirm that the cable is seated, etc etc so that I don't have charge voltage chilling on the plug at all times
Sounds like a neat project
I did not like the state of safety in off-the-shelf chargers so I'm doing it myself LOL
I know that feeling!
These relay boards work by having a common 5v rail and multiple "control" lines that are pulled to ground to trigger individual relays
Modern mcu boards are only 3.3v tolerant
so there's no way to use one of these with a samd21 or something without additional hardware
If you have an outboard chip to drive the relay lines, you could choose one that supports whichever logic levels you need.
It's got to be just regular ol gpios :(
That's why I mentioned GPIO expanders and shift registers, which could deal with fanning out two signals to 4 (or more) as well as dealing with different logic levels.
Got it. (?)
This is the schematic for these common relay boards
I bet the opto side will run on 3.3
I'm guessing so, if Vcc and JD-Vcc are indeed separate
They are
Have one and have continuity tested
These boards seem to use an "817c" optocoupler
Can't seem to figure out what the voltage minimum is in the datasheet
Yeah, the current transfer ratio should be at least 50%, so if the resistor passes 1mA through the LED, it'll provide at least 0.5mA to the transistor base, which is probably enough to operate the relay coil. Those relays probably take 100mA or so on their coils, so if the transistor provides a current gain of 200 (many do), you should be in good shape.
Optocouplers are essentially LEDs, so they’re current-driven, not voltage driven. I would imagine that if you can find out the forward voltage and it’s less than 3.2v, you should be able to replace the resistors to work with 3.3v logic
The forward voltage for that one is pretty low (1.2V typical, 1.4V max) since it's an infrared LED. I don't know the value of the current limiting resistor.
However, I suspect that the stock resistors would work fine with 3.3V
ppl do basically exactly what I want and have no issues apparently! woo!
Hanging drywall is fun, you might want some drywall tees and maybe stilts if you're doing a ceiling. Taping and spackling is a whole 'nother skill set (but a 12" spackle blade makes it a lot easier and quicker)
Has anybody done a streamlined tutorial on how to change the SERCOMs in a SAMD board?
https://www.sigmdel.ca/michel/ha/xiao/seeeduino_xiao_sercom_en.html
I found this but it doesn't really tell you how
i have a lift. im just procrasticnating
Question - will pads assigned to SERCOMs still work as GPIOs if you've not done serial.begin etc?
ie use a pin for gpio, then serial, then gpio without power cycling or recompiling?
not 100% but I suspect you could do Serial.end() then init the GPIO
not sure how to de-init the GPIO, or if you need to, maybe just set pin mode back to default??
hmmm
First attempt at white chocolate creameux setting in the fridge
gimmie
Going to attempt strawberry cupcakes with white chocolate creameux frosting with sliced fresh strawberries on top
ooh
She wanted strawberry cupcakes with cream cheese frosting, figured I’d try to go a little gourmet for her birthday tomorrow
ah
I was hard pressed to find a pack of mostly ripe ones from Walmart this evening though
i want a pizza
is dominoes as terrible in the usa as it is here?
Yes
hehe
Dominos here is great
Papa Johns is where it’s at
People eat Papa John's????
d
Other than the founder being… yeah
well that too. but i had it once, possibly the worst pizza i every tried
But I don’t have papa johns anywhere close so we just buy Costco pizza fresh
classed as non edible
$11 for a highly cheesy pizza is great
Domino's is my go-to... so good around here
$11, sounds very expensive
Equivalent to an extra large from other places
Pizza Hut is dead here
Yeah, Costco pizza is best price for value of all to go pizza
Granted it’s super simple choice wise: Cheese, pepperoni, or half cheese half pepperoni
the only pizza close enough to walk to here, is pizza pizza... which on a scale of 1 to 10, where 2 is eating the box... its a 1
Costco is.. 5 minutes drive wise
Little Caesar’s varies so wildly
mostly cause i ate it ever day at school for 5 years
it was $1 a slice. not worth it
haha
Most of the time we do homemade, but we had a Costco gift card so we’ve done a bit of Costco pizza lately
i do home made, but i dont have any dough handy
need to make some
so the only choices i have tonight are dominos, and pizza nova (which is an 8, but ive had it the last 3 times)
they all seem to have rigged the prices to be identical. $31 for 2 pizzas delivered
$6 delivery charge. amazon should do pizza
We have a place 10 minutes up the road called mod pizza which is pretty good
They have a “build the pizza in front of you” setup
Pretty good. I usually do a buffalo chicken pizza with blue cheese, Parmesan, bacon, and such
Pretty good
99% od all pizza places here build in front of you
mostly cause they have no choice, the restaurants are so tiny
i used to have 6 pizza places outside my door. now i got snow. haha
alternatively, i can make mac n cheese
or fettucine alfredo. hmm
Can’t go wrong with pasta
i have pasta 3-4 days a week.
mmm pasta
Lol
Sure, if it’s a meal in New York, or can be one for you too lol
Nova lox bagels
Strawberry cream cheese
Pizza sauce and cheese
I have issues with Domino's political views, so I avoid them. Pizza Hut is okay. I used to go to the local Al's Pizza, but they closed when their building got demolished. Now I drive up to Maryland to another good local joint, King's Pizza. There's also Mama Lucci's a few towns over, a great Egyptian/Middle East/Greek/Italian place.
I've never heard anything political about Domino's... Most local places suck, unfortunately
None pizza with left beef
100% beef free
i only eat the left side of the pizza
😛
haha
anyhow
its hard to keep track of the companies whos former owners have said really dumb things recently
luckily most of them arent in canada anyway
While I like Papa John's Pizza, the local ones are all owned by a local crank I prefer not to do business with. I was pleasantly surprised to find good Chicago style pizza locally.
I never had Papa John's... they don't really exist around here
They’re much bigger in the south and southeast than anywhere else
local franchise owners can ruin everything. the local pizza hut owner/manager here is a shambles. if the pizza comes in 2 hours ice cold, they offer a $5 discount
assuming they deliver it at all
ive never seen the same driver twice
Geez
yeah they are bad
Delivery where I am is hit and miss
the one near my old place was good
We can only get grub hub or Uber eats so selection is not great
Half the food comes in either wrong or cold
There was one of the classic wedge-window Pizza Huts up on I-70 near Baltimore with a real fireplace and good food and service. I'd stop there when I was travelling that way. Unfortunately, they closed their doors a couple of years ago.
There is one Domino's here that's absolutely horrible because the owner of that franchise is an idiot... He also owns a McDonald's down the street that's just as bad
We usually just stick to what’s within 5 minutes of where we are
uber eats is on the blkacklist
Your personal black list?
they feel like laws are too inconvenient for them
Delivery services are on my black list
Ah, yeah contract worker laws here suck bad
Not many places deliver where I live anyway, but I'll usually just take my trike and pick things up (unless it's nasty out, when I'll drive)
well more than that. they ride bikes on sidewalks, block roads, park in bike lanes
and then complain its not profitable if they have to obey laws
anyhow
haha
i want them banned from the city
and it may happen
I ride my trike on sidewalks a lot, but I try not to be a menace or block things.
I ride my bike on the sidewalk a lot because otherwise cars try to run me over
sidewalks here have 1000s of people on them.
if it was in the suburbs that would be different
My area is kinda suburban
My area is.. sprawl
I'm out in the country, sidewalks are sometimes empty, but usually I'll see someone walking their dog or somesuch
Car land
Gotta drive to really go anywhere here, or long bike ride. Sidewalks are generally clear, occasionally someone walking around... sidewalks are also usually wide enough to pass someone safely, or I stop/slow [usually not going fast anyway]
Amusingly, in places where the sidewalks are really crowded (and here I'm thinking like New York City), it's safer to bike in the streets, as the cars generally aren't moving very fast, and they're accustomed to seeing bikes.
typical quiet day here
That is ... quite.
im not sure what that is. film fest maybe?
stage up in the back gorund, maybe a concert
they loooove to close that road
ha
my condo was out of frame on the right of that
blue jays /maple leafs / raptors stadium isnt too far either. its just crazy busy all the time. even at 4am
much quieter where i am now
Imagine if malls were right next door to living accommodations instead of the edge of town
Best for me
No more long distance to shopping
Takes me less than 5 minutes to walk into the nearest "mall".
the bane of laptops everywhere (dramatic pause) bed comforters (thunder lightning sting sound effect)
P is pwm right?
@delicate stream
Its the Micropython pin number (which is also the RP2040 GPIO number)
Yeah it says Micropython right there in color chart. If it was CircuitPython would probably be labled as D. Seems like a naming convention for GPIO than pretty pins for buses.
I don't own a single Seeed product though.
Is that a pico powered Pi Hat for something @gusty torrent? 9v or 5v barrel jack input to the capacitors?
Almost looks like IDC interface for something... perhaps you're own version of scorpio, RGB matrix driver, pyportal kind of thing?
No label on the 8 or 14 pin dips so no way to know what it does. That's a ton of resistors and caps though.
Is it audio related? The number of caps makes me feel like it is
Please don’t ping me specifically for random questions — things like that where anyone can answer
You're pretty close. Its a dual-purpose USB/I2S DAC that can be connected on the I2S via hat header. Bitbangs the I2S via PIO.
Ahh
Second version of one that originally appeared in a japanese magazine about a year and a half ago.
Nice!
Original version had USB only, no hat connector and lousy noise isolation.
Lol, I bet there’s a lot less parts on that version
Big changes
Gonna go BOM shopping tomorrow
In THEORY I can get everything at one shop
The only iffy things would be the DC-DC converter to generate the +/-9V, the 3.5mm jack and the audio-quality op amp.
Good luck :0
I have envy. All I can do I order and wait a week
Are you going with a switched-capacitor converter or an inductive one?
Its not my design but this is the component: https://akizukidenshi.com/download/ds/minmax/mau.pdf
Unrelated: is 2023 the year of baby toys from companies that have nothing to do with babies? XD
clearly, the corporate mass surveillance apparatus has seeded your advertising profiles with baby stuff because Adafruit has been talking about baby stuff
Should we cancel babies so this can’t happen again??? No babies, just POOF adults
I'm so happy. I got my new split ortho keyboard working with modtap and tapdance and all that. Next up, adding in BADUSB
I dunno what modtap and tapdance are, but yay keebs!
both let you make a key have multiple functions. with mod tap, tapping the key sends one key, holding it sends out a modifier like shift. tap dance sends whatever you want depending on how many times you press the key in a given time
i just wish i could turn off the darn green leds from the chips that are shining through my case.
i have a tapdance on "`" to make a code block on discord
That's a great idea
and another one on spacebar so double tapping it (or any even number of taps) sends 4x instead of 2x, for indenting
how do you make a code block on discord anyway? isn't it three graves?
exactly, and i get it written with double tap on grave
does it somehow automatically add it to the beginning and end of what you have written?'
Is that what you call `? I always called it a reverse tick
can you share the code?
yes, but it is QMK
i'm on KMK, but I'm sure I can get it to work
it disappeared
VSCode
with one of the prebuilt color themes
so, pressing the ` key quickly, 2 times or more, sends the triple backticks for openning and closing, and then moves up so your cursor is inside the block
oh, does your code create an empty codeblock?
i usually proceed by:
- copy some code
- use the tap dance
- Ctrl+V it
gotcha
and for the spacebar ```c
void td_spc_each(tap_dance_state_t *state, void *user_data) {
unregister_code16(KC_SPC);
register_code16(KC_SPC);
if ((state->count % 2) == 0) {
unregister_code16(KC_SPC);
tap_code16(KC_SPC);
register_code16(KC_SPC);
}
return;
}
I think I'll do mine a bit differently. I'll have it send home, enter three graves and a new line, hit end, then another new line followed by three graves
that way i can do it in the reverse order. paste code then add the code block stuff around it'
it is a little messy with (un)register instead of tap, so i can also hold the key too
im working on a custom PCB design, my current idea for the layout is "weird" to say the least 🤣
just having the enter key beneath the quote key is odd
ooh, do you have any pictures of the layout you can share? i like looking at crazy layouts
I'm subbed to OLKB on reddit just to see what crazy stuff they come up with. It really makes me want to make a keyboard with chocs
i still need to make further thinking about layout, removing the 2 columns to the right of the letters may be more trouble than i currently think it will be
note: PDB isn't even synch with the layout image
I like it. what are the plans for the big areas under the keys?
touchpad or something?
screens, one of them (big under right thumb) with touch sensor
very nice. I was thinking my next keyboard would have some way to control the mouse. I wasn't sure if I wanted a trackpad, a nub, or a trackball.
now you've given me a new idea. touch sensitive screen
my other big plan for this weekend is to get WSL working so that it doesn't force Virtualbox to work in software emulation mode.
WSL takes like 5 minutes to get setup
well, a little longer if you also take into account the time that the particular distro will take to download and install
but WSL itself, is fast to configure
yeah, i had it up and running recently. i think i found a solution to the virtualbox problem too.
and the best thing is, im only using a little amount of pins to drive all of that, i have like 17 unused GPIOs on each half
i will break them out on a connector so i can test other hardware with jumper wires easily 🙂
That is really cool
shift registers for the win
with my keyboard right now, i just have one rp2040 running everything. it can fit all twelve columns and five rows by using the I2C connections to two separate TCA8418 breakout boards'
im scanning all 29 keys on each half using only 3 GPIOs: SPI(SCK+MISO) + CS
slick
and the touchscreen's IRQ pin is also wired to the input of one of the registers, so it doesn't take an extra pin
All of this makes me want to buy a 3D printer. That way I can easily attach any sort of additions to this keyboard. I can use this as my 'test keyboard'
No home is complete without a 3D printer
i can't mooch off of my coworker's printer forever. i'm happy enough he printed me this one case
you making me feel bad, guys... #help-with-hw-design message
I don't get it
All of that was 100% done by me
nice
you both saying you want/need 3D-printers, and i havent used mine in like 4 years
looks like you've mastered 3d printing
oh, lol
i'm sure if i had one, i'd use it only sparingly
I have 5 printers, but haven’t used any in a while >~> not enough time or energy to do maintenance and watch prints…
printing was the easy part, designing (and sanding) were the troble part
there's also 2 others i built and sold, i dont think i have pics of them on hand
two printers?
two other rubik-cube-like puzzles
ah, ok
That's -5.8 feels like -25.6 freedom units.
that all blue puzzle on the right, I've got one just like it around here. I think mine was made by mefferts. it's really cool
It’s 24F currently here
yikes
oh, the mixup
i hadnt stickered mine as the design has bad clearances and can barely turn it
but i love the puzzle idea
sounds like you made the puzzle perfectly. the one i have by mefferts also has bad clearances and can barely be turned
a balmy -13 here
it's -9 C here. 17 F
it's warmer than they predicted yesterday. it was supposed to be in the single digits
I just have one 3D printer, and it seems to get used every few days for something (bits and bobs for costumes, repair parts, decorative items like this Terok Nor/DS9 model we used as a tree topper, project parts, brackets, custom tools, etc.)
That’s a nice topper
i never watched star trek, but that looks really nice
but if i had a 3d printer, i think that's what i'd use it for. like i have a shelf that's missing a bracket. I could create and print a replacement. Little stuff like that.
Exactly. The little coin cell tray in my water filter broke, so I just printed a replacement
You should fix that 
I feel I can't rightly call myself a nerd until I do. That said, I have watched Battlestar Galactica
The original one, or the reboot?
reboot
I need to finish the reboot… and rewatch the original
the one with Edward James Olmos
