[wanton thistle]

years later down the line yea maybe I should replace that but it still works

temporary fixes often become permanent 😛

[wooden schooner]

Idk man, this is Apple, popularizer of planned obsolescence

There is probably a timer in there that artificially degrades performance after a pre-programmed delay

[wanton thistle]

go one further; a paid subscription to use the cord.

[wooden schooner]

Oh you're right

That's the Comcast version

[umbral phoenix]

car manufacturers too

[wanton thistle]

I was thinking BWM (heated seats)

opps, BMW

[wooden schooner]

Fill me in?

[wanton thistle]

https://www.theverge.com/2022/7/12/23204950/bmw-subscriptions-microtransactions-heated-seats-feature

[umbral phoenix]

I'm fine with a subscription IFF there is ongoing improvement, but to pay forever for something that's manufactured in is infuriating

[wooden schooner]

Wt ephhhh

[wanton thistle]

Seems ripe for hacking IMHO

I mean, how easy is it to control a seat heater? Ya know

[wooden schooner]

The price is also insanely high

[blissful roost]

Anything is easy, when the Not Safe Anywhere has all the backdoors...

[wooden schooner]

It was already unacceptable on principle/precedent alone but the price is also bonkers

[wanton thistle]

that is why I am keeping my 2009 Subaru until its dead dead.

[blissful roost]

I'll build myself a Mustang when I move to the US.

[wanton thistle]

Would you do an Electric Conversion?

[blissful roost]

Nope

BMW V8, 4.4ltr.

[wanton thistle]

On the opposite end, I wish we had more access to those tiny cars with 1.8L engines

[late fulcrum]

That's a good-looking solution, but I like to make the splint longer so it secures the things plugged into the ends as well.

[wooden schooner]

This is a good point, but I would think the connector of the other piece, which is usually reinforced, would be a better place to end the splint than normal unreinforced insulation further down the wire?

I did consider it and that was what came to mind, would appreciate corrections

[blissful roost]

Dynacorn make original spec chassis and bodywork from fresh steel and the pricing is reasonable.

I want to build a '67 Fastback, keeping with the original look as closely as possible.

[late fulcrum]

The connector is usually sufficient, otherwise you tend to stress the wire at the attachment point unless you have a compliant support for it.

[blissful roost]

But, all the internals will be modern.

[wooden schooner]

Yeah hm, that's a good idea, I'll cut a slightly longer one that supports the connections, esp the analog end. Thx

[lusty fossil]

Saw a Lucid on the highway. Boy I guess that car must be attractive to somebody. Not me though

[blissful roost]

?

Not something I am familiar with.

[wooden schooner]

Last year's model of running shoe in goblin green are attractive to me in price tag only

[lusty fossil]

Luxury electric. Very new

[blissful roost]

Oh lawd!
I wish I hadn't looked now.

[lusty fossil]

It looks like a 2012 Oldsmobile was a long term corticosteroids patient

[wanton thistle]

welp I cant afford that

but let me play around with the designer anyway 😂

[tardy badger]

After over two days of nothing, fedex finally admits there is a delay with my package. It’s amazing FedEx hasn’t been uprooted by a company doing logistics that uses real time data to immediately inform recipients of delays

[late fulcrum]

I suspect that has happened a few times, but then FedEx just acquires them (FedEx is at least 9 different companies doing business under the FedEx name)

[wooden schooner]

I am not positive on high-tech logistics "disruptors." I would rather they treat their employees better and consumers (somehow) learn how to wait.

I say this as someone who often gets comically impatient about insignificant orders.

The problem with customer impatience is that then you get monopolies like Amazon that use their exploitative logistics arm as a moat against competitors.

[umbral phoenix]

excessive convenience begets all kinds of ills

dark patterns, security and privacy problems, etc

[wooden schooner]

Using the convenience as justification for the supposed necessity of unethical business practices

[late fulcrum]

I just don't buy from spamazon.

[tardy badger]

I don’t necessarily care when packages come, it would just be nice given all the data that logistics companies collect that we could at least have been informed about a product and service we paid for.

I’m not necessarily side stepping other issues with logistics companies, I worked for FedEx and it sucks the situations they put workers in

You get one person responsible for loading 3-4 vans with anything from envelopes to 200lb+ boxes that you usually have to move by yourself

Like after the new year when everyone orders treadmills

Or other heavy workout equipment. Not to mention boxes of pet food from chewy. That job was rough

[dusty citrus]

eh smaller companies aren't often that better either
they're less prone to be scrutinized unless they don't try to comlete with bigger companies
(they send dogs to find issues and put them out of market)

also bigger companies do even use third parties for cheaper labour or in other words they don't get into issues if they don't comply to laws and suchs

[ebon dew]

I swear they're just making up their own definitions of words now.

this is what happens when you have administrators create a course that has anything to do with programming.

[fierce prawn]

Hmm
It's a package

[ebon dew]

it's the "that someone else wrote" part that is incorrect. you can write your own libraries. but you're not wrong, it also describes a package, or even perhaps an archive depending on what's in the archive, also vaguely describes a container, and plenty of other things that are collections of scripts.

[ebon dew]

sorry for the rant but these types of things are rampant in the course i'm taking. i continually get test answers wrong due to factual definitions vs definitions they make up and expect extremely semantic specific answers which are full of half truths.

"What is a way Microsoft created to view running processes on a windows pc"

A) Task Manager

B) Resource Monitor

C) Process Explorer

the correct answer was C. feel free to google that one.

I failed that test by 1 question because I chose A

so yes, i'm very frustrated and need to vent sorry.

[lusty fossil]

I once failed an excel skills assessment (automated) because I used g sheets and didn't know where all the menu items were and that was really what was tested. In all the officey jobs I've had I've consistently been the person who other people call for help with that application.

Skills assessment was part of a job app

[cursive swan]

Hello AdaFruties

I'm brainstorming projects to do in 2023.
And looking for ideas for interesting things to do.
I want to do 12 projects in 12 months.

Hopefully some will be new or first time things. Innovative use of Adafruit boards.

[cursive swan]

That must be very annoying.

[weary fiber]

fixing integration tests at 2AM while listening to chill jazzy music

we out here vibin

[wanton thistle]

Anything with LEDs. Maybe a RGB LED that cycles, or a small lamp.

CC-CV power supply but using op-amps.

[fierce prawn]

Adafruit qt py or adafruit keyboar + neokey breakout + mechanical keyboard switches

[tardy badger]

Make a watch. 🙂

[late fulcrum]

I like building weird art projects like one of those widgets that hangs from two strings and draws on a wall (or, similarly, a blue laser pointer with a couple of servos to aim it, and a sheet of glow-in-the-dark material for an evanescent drawing). Movie props are good fun too, like a flux capacitor, divergence meter, or proton pack.

[frigid tiger]

Vfd watch, nixie watch, mechanical watch, LCD watch, OLED watch, e-ink watch, magnetic BB watch, flip display watch,

[tardy badger]

I think a stretch goal for 2023 is to develop my own cell phone

[late fulcrum]

I did build one from a kit once. I've been toying with upgrading it for G4, but maybe I should see if there's a G5 module... Oh, there is, the Telit FM980M is one possibility!

Sure enough, Simcom has some offerings as well, such as their SIM8380G-M2

[tardy badger]

U-blox has some nice cellular modules

~$50 a pop

If I do an NXP A53, 8GB of DDR4, and a ublox module, I should be able to manage for like $200 a unit I think

The PCB will be the most expensive part

[lusty fossil]

Would you not need high speed design tools for that?

[tardy badger]

Eagle can handle it

[lusty fossil]

I meant hardware

Scope etc

[tardy badger]

Oh, yeah definitely

I’d need a GHz scope

[lusty fossil]

At least right? I'd think multiple GHz

[tardy badger]

A multichannel GHz scope should be sufficient

Plenty of people do it without though. Just have to trust (expensive) iteration lol

And do very thorough design reviews lol

[late fulcrum]

I don't think you need to debug the cellular end of it directly: that engineering is already in the modules. The communication with the modules is simple enough with even a fairly basic scope (if you even need a scope)

Weirdly, I end up using my ancient 50kHz scope more often than my fancy GHz one.

[tardy badger]

I have a 100MHz handheld scope that would probably be fine

[lusty fossil]

Battery powered.

?

[tardy badger]

Yup

Wireless charging

[lusty fossil]

Which one?

[tardy badger]

https://www.mouser.com/ProductDetail/Texas-Instruments/BQ51051BRHLR?qs=E2%2FxqS9xjzqw0w1tVVJkeQ%3D%3D&countryCode=US&currencyCode=USD

I’m already trial running it with my watch

[lusty fossil]

Oh I meant which scope sorry

[tardy badger]

Oh, just a aliexpress variety

[lusty fossil]

Oh ok

[tardy badger]

I’d have to get a test SIM card but those are pretty cheap, I think you can get them for like $10-$15

Imagine it being a bare metal circuitpython phone lol

[lusty fossil]

Lol

[tardy badger]

I would totally send one to Scott and any other circuitpython core dev to help bring it lol..

I imagine it would be easier to put circuitpython on the NXP i.MX.8 Nano A53

[mystic sphinx]

Hey all. I brought on an engineer for a project but it’s been such a long time and nothing has happened. Where are some good places to find a circuit board designer?

[tardy badger]

Check out https://jobs.Adafruit.com

[mystic sphinx]

Sweet thanks!

[late fulcrum]

Depending on your carrier and plan, it can be as cheap as ... free.

[tardy badger]

Alternatively, if you’re interested in learning we have a #help-with-hw-design to get feedback and advice

[mystic sphinx]

You know I really should.

[tardy badger]

I was talking about one that came with usage attached to it so I don’t pay for a contract lol

[late fulcrum]

Yeah, Ting and similar outfits offer those.

[tardy badger]

Yeah

[mystic sphinx]

It’s not the most complicated project. Especially just a Feather RP2040 connected to an RFID Scanner

[late fulcrum]

Since I already had a contract, I opted for the free SIM

[tardy badger]

I think the UBlox and similar modules come with IMEI numbers too which is good

[tardy badger]

Ah yeah, definitely doable without hiring someone

Using prebuilt modules saved a ton of time

[mystic sphinx]

Oh sweet. Okay, good to know.

[tardy badger]

Adafruit has an RFID reader board that would save a lot of time too.

[mystic sphinx]

Means I can start working on the devkit. I’m going to be using a Flipper Zero

[mystic sphinx]

Probably won’t be using this one but it’ll be close

The PN532 chips are quite expensive

[tardy badger]

https://www.adafruit.com/product/364 this one?

That’s what I recommend since it’s already assembled, I need to worry about figuring out the coil or matching network, etc..

It’s not hard if you use premade coils and whatnot, but this definitely saves a lot of guesswork

[mystic sphinx]

Yeah

I used this one for the prototype, and while it works pretty well I can’t imagine a cost effective way to mass produce it

[tardy badger]

Ah, I see

[mystic sphinx]

NXP has some new stuff on the horizon I think

At this rate, I just need to transplant an RP2040 feather onto a hexagonal shaped board

And link in some RGB Leds and a cellphone speaker

My engineer told me supercapacitors might be the way to go instead of batteries but I’m not too sure about it.

It’s a kids toy

[tardy badger]

https://www.digikey.com/en/products/detail/TRF7963ARHBT/2798686

This would be a great option

If you are doing NFC specifically, highly recommended the nRF52840

[mystic sphinx]

I’m not sure yet

[tardy badger]

It has a built in NFC peripheral

[mystic sphinx]

It’s a microcontroller?

[tardy badger]

Yea

It’s a cortex M4

[mystic sphinx]

Hmm okay I’ll check it out.

[tardy badger]

It also does Bluetooth

You can get the dev kit which comes with an antenna for nfc for $50

[mystic sphinx]

Hmmm

[tardy badger]

Worth looking into if your range is really short

[mystic sphinx]

Yeah it is

My main concern is mass production

If I can just buy coils then I wouldn’t need to worry about pcb designing a coil

Antenna ** sorry

[tardy badger]

Yeah, you would just put an SMD/SMt connector for whatever coil you choose

[mystic sphinx]

Sweet.

[tardy badger]

They have W.Fl and U.Fl style connectors for antenna

[mystic sphinx]

Oh sweet

And then, how hard is it to actually design a circuit board? I know how to read schematics (sorta)

In theory would I be able to drag and drop some Adafruit components and rearrange the parts?

[tardy badger]

https://www.digikey.com/en/products/detail/1462362131/13997591

Well, for using the nRF52840, you would want to use a module that has NFC pins broken out, certified module if you can because certification is really a headache

That antenna uses a small molex connector that they list in the drawing

[spice moss]

so i can go some designing now as i got 2 ruuvi tags

[tardy badger]

For the Adafruit board, I don’t believe they break out the NPC pins

[mystic sphinx]

This already sounds confusing

Lmao

[tardy badger]

It’s okay, it can be at first

[mystic sphinx]

I’ll do some more looking into it 😂

Is it worth getting someone in Fiverr to do it?

[tardy badger]

Definitely get the Nordic DK for the nRF52840 and play around with it first to see if it does what you want and if you’re comfortable with the development environment

[mystic sphinx]

Atleast for the pilot run

[tardy badger]

It’s why I suggest the DK. No hardware design to develop the firmware and usage

[mystic sphinx]

Yeah

I’m used to plugging things into a breadboard and getting it to work. Lol

[tardy badger]

I get it lol

[blissful roost]

I started work on hand-drawn PCBs a few years ago, but I still haven't produced any yet. 😛

Been lacking a safe space for all that since my dad sold his house.

[wooden schooner]

In brand-appropriate language: "Boom."

It's not the sturdiest thing, but I think it'll snap before the other pieces take damage so that's probably good.

[blissful roost]

You need ElectroBOOM for that.. 😅

[ebon dew]

if it works it works

[dusty citrus]

are all positive photoresist materials thin like a film/spray like stuff?

Auegh

[rare gulch]

As long as Adaboxes have been on hold, are existing subscriptions also just on hold, not cancelled?

[manic tide]

Anyone codes in XML? (I have 1 day experience)

[tawny halo]

What do you need help with?

[manic tide]

I'd like to align an image with a slider, so that the values match

Here's how it looks now

The code for this part is

      <RectangleWidget Size="400, 50" HorizontalAlignment="Center" Subtexture="{Textures/Gui/Segments}" Margin="40, 10" FillColor="255, 255, 255" OutlineColor="0, 0, 0, 0" Name="Segments"/>

      <SliderWidget Name="EditBatteryDialog.VoltageSlider" Granularity="1" MinValue="0" MaxValue="15" HorizontalAlignment="Center" Margin="40, 0" />

I've got an advice to copy margin from the slider element, but it seems not to have worked

Furthermore after some experiments, I think horizontal margin is useless in conjunction with horizontal alignment by center

Also, the canvas widget size is 500 by 300

[tawny halo]

Hmm, I don't think I have enough context here to be able to help. What platform is this you're building it on?

[manic tide]

Where can I see that?

The game engine is proprietary and written in C#

You might give me more context as where I can determine that

[blissful roost]

<@&327289013561982976>

That's grossly inappropriate

[hot ingot]

Idk it may be fake, but I think this is the right thing to do

[blissful roost]

It's very fake.
Discord does not reveal your IP or friends list... And a baseless accusation is just disgusting.

I strongly recommend deleting the message.

Those messages are typically created in an attempt to tarnish the reputation of an innocent person.

https://discord.com/blog/security-discord-and-you#:~:text=Because Discord uses a client,sight from any bad guys.

[whole jacinth]

there is some risk if you (accidentally) click on a malicious link sent through Discord, and that might be a kernel of truth behind these kinds of reports

[blissful roost]

Yeah, only via external links.. whereby the hosting server can log a visitor's IP.

[hot ingot]

I deleted the dm

[manic tide]

so.. any xml tips?

[ebon dew]

https://tenor.com/view/snowball-snow-merry-christmas-gif-15876113

[proven olive]

So I'd like to explain why these types of copy/paste things aren't particularly useful. Don't worry, you're not in trouble - We don't punish people for trying to help. Just trying to be informative.

So, first. Usernames. We can all change our usernames on discord as we wish, so immediately that's not particularly useful. It can also be fake - Whoever makes one of those can put someone's username in there and then suddenly people are "Oh no!" about that person. Not great.

Beyond that, though? As Armand mentioned, Discord doesn't reveal your IP, but even if it did? That's literally how the internet functions. You go to a website and that website knows your IP - that's how it knows you are you. Knowing an IP doesn't mean they bypass any of your security - your router, your firewall, etc. Revealing your discord username also isn't particularly useful.

For some good security tips:

• Don't accept friend requests from people you don't know.
• Don't click on links where you don't know where they go to, and double-check the link itself.
• Don't tell anyone personal information (What e-mail you used for an account, the account password, security questions, etc).

And, as always, if you have any concerns with something you can definitely DM one of the Community Moderators or ping the @community moderator role (Like @blissful roost did, thanks Armand!). We've dealt with this stuff a lot and are more than happy to ease your concerns.

[whole jacinth]

additional info if you want to make a useful report about a user who might be changing their username to evade reporting: you can turn on Developer Mode, and that will give you a right-click menu item to copy the unique Discord user ID, which is supposed to remain constant regardless of username or nickname changes

[hot ingot]

Oki

[rapid geode]

O-o

[late fulcrum]

XML is pretty straightforward for basic use, but (like Unicode) includes the possibility for bewildering amounts of complexity if you like.

[manic tide]

As you can see, I want to align two pieces. currently I have no idea on how to.

I've had one though to design the image with the spacing in mind, but I think that's not fair

[crystal ore]

It'll just depend on the rules and syntax of the particular GUI framework you're using. This sort of thing isn't defined by the XML language itself, but by the app.

[manic tide]

Where can I find one?

[crystal ore]

Find one what?

[manic tide]

The gui framework

Since I don't currently know what I am looking for, I am asking what it might look like to have a some image of what to look for

[tardy badger]

Merry Christmas to those celebrating today!

[crystal ore]

You'd want to find the documentation for whatever game engine you're using.

[manic tide]

The engine is handmade by the person that we don't have any way of contacting. Sort of abandon ware faith.

[crystal ore]

Then your best bet would probably be to compare against any other examples of how people have used the engine, and try to reverse-engineer what kind of commands it supports.

[manic tide]

I have a full C# decompilation of it that I can try and study

But I would end up aimlessy going around trying to find something that I have no idea how it looks.

[tardy badger]

The best thing I got for Christmas was this:

I had to sell this card back in October to pay bills. I sold it to my wife’s friend who collects cards. He got it graded and then gave it to me for Christmas and honestly it means a lot because I wasn’t sure I’d be able to buy the card back

[lusty fossil]

Nice!

I got sheets.

I'm very happy with them

[tardy badger]

Also really loving this gold filament I got myself

I need to rework the channels for the Watch bands so they angle down

[rapid geode]

pokey man card are still a thing?

i wish my hockey cards were worth more than 10 cents

[wooden valley]

Just got this super dope gift that I definitely didnt know i was gonna get, but idk what to make first

[rapid geode]

oh neat. i have plans to make organisers in my shed, but havent got there yet

[wooden valley]

Litterally have so much stuff it’s impossible to organize

[rapid geode]

ha

[tardy badger]

Huge even, that graded card is worth north of $600usd

It’d be worth at least double if it was a 10

But 9.5 gem mint is still incredibly good

[rapid geode]

wow

nuts

do they have a purpose? its a game right?

(i dont know anything about it)

i think hockey cards died cause they have no real value. it was all just made up speculation

vs MTG where you "want" the card for the game

[lusty fossil]

Pokemon, 99% sure

I don't know how many people actually play but that's the theoretical value

[blissful roost]

I still have some old Pokemon TCG decks around somewhere.

[lusty fossil]

I enjoyed collecting as a kid. Not my thing these days but glad they are still around

My collection was special to me but not particularly valuable

[blissful roost]

I was there, in the beginning.. 😛

[lusty fossil]

I was too

[blissful roost]

🙂

[tardy badger]

I was there in the beginning as well

Collectors slabs from Burger King lol

There’s actually a lot of people who still play the card game itself

There’s huge tournaments too

Lots of prize money in it

And the old cards that are graded fetch huge money

[blissful roost]

I might still have the 1st movie set...

I hope so.

[rapid geode]

the pokemon deadpool movie was ok

[blissful roost]

You mean Detective Pikachu ?

[rapid geode]

yes

[blissful roost]

... I have serious question about that film.

[rapid geode]

ha

why they made it?

is picachu in the mcu?

[blissful roost]

The kid couldn't tell that Pikachu... sounded JUST LIKE his father?

🧐

[rapid geode]

he was wearing clark kents glasses

[blissful roost]

hahahhaa

[blissful roost]

Pikachu vs Wolverine ?

[rapid geode]

now thats a fight

we did a ryan reynolds movie once. it made like $80000 in the theatre

Does adaptive layers help any? Idk if that feature’s still in experimental, my Cura’s a few versions out of date

[wooden valley]

how would I convert a bread board project?

[lusty fossil]

To?

[wooden valley]

so Im new to electronics and want to make this https://lastminuteengineers.b-cdn.net/wp-content/uploads/arduino/Wiring-DHT11-Module-with-Arduino-and-LCD.png

but my larger breadboard is bigger than the one on the right

so I want to convert the wiring for mine

would I just wire it off of where I place the lcd?

[lusty fossil]

What hardware do you have exactly?

[wooden valley]

dht11 lcd 1602 module a 830 tie point bread board and a mini breadboard

[thick wind]

Breadboard size shouldn’t matter in regards to wiring

[wooden valley]

so should I just place the wires spaced relative to where I put the lcd

[thick wind]

As long as the points that need to be connected in a row are in the same row, the exact position of pin connections shouldn’t matter

Yes

[wooden valley]

ah ok makes sense

[lusty fossil]

Oh I sse

[wooden valley]

and what about this

[lusty fossil]

I misunderstood the question

[wooden valley]

would I solder 2 jumpers?

[lusty fossil]

So that indicates a connection

Solder?

[wooden valley]

it indicates that 2 jumpers have to connect?

so how would I connect the both to the same point

[lusty fossil]

It indicates you have to create an electrical connection in some manner. You can use the breadboard to do that

let me look closer at the full image

[wooden valley]

let me wire it all

[lusty fossil]

So if you look at these pins, circled in pink, they are all connected together in a column inside the breadboard

[wooden valley]

oh ok yea

[lusty fossil]

Don't get too married to the exact layout they show, since you can do your own on your larger breadboard

[wooden valley]

I kinda think me and this layout are past marriage

lol

[lusty fossil]

Note that on many breadboards, these pins (pink and green) are NOT connected, and must be joined if you want to make a long power or ground rail. Those outside sets of holes are most commonly used for power and ground.

image incoming

Note pink and green. Same idea applies for the row (or column depending on orientation) of ground holes

[wooden valley]

yea mine is

[lusty fossil]

Oh they are?

That's convenient

[wooden valley]

ik

[lusty fossil]

There are use cases for the other way but I digress

What you could do is layout your project like this and then ADD the sensor to the right and wire it as shown. It takes a little brain stretching to convert, as you put it, but it's part of the fun!

[wooden valley]

as it is my brain barely gets whats going on

soooo

[lusty fossil]

You'll get there!

Let me see if I have time to help more. I have to go to Christmas dinner soon but I'll do my best.

I am also a terrible guest who will check his phone compulsively so you may see me again

Can you link to the guide/help page that that image came from?

[wooden valley]

https://lastminuteengineers.com/dht11-module-arduino-tutorial/

[wooden valley]

same, but Im taking my project with me lol

[lusty fossil]

Fortunately I am having dinner with a fellow engineer who is an educator so he'll get it

[wooden valley]

can I swap 5v and ground?

[wooden valley]

ah thats nice

[lusty fossil]

Depends on what you mean. Generally do not do this!

Do you mean put ground on the red rail and power on the black?

You can but it's not a good practice, it will confuse people

[gusty torrent]

Should be aware that the dht11 is pretty inaccurate. The other modules from the same company are somewhat better though.

[wooden valley]

I dont need accuracy because deployment will just need to know if there is a significant change

[wooden valley]

because the documentation for my kit shows 5v in the middle

but this pinout shows

vcc on the left

[wooden valley]

where would I connect the left wire from the sensor? on the bread board or the arduino

[lusty fossil]

Ah I see

Just make the connection from the power column (power bus) as shown in your documentation

Same with data

Gotta run, good luck!

[wooden valley]

[wooden valley]

what soil sensor do you guys recommend?

[cold jolt]

I didnt know this worked

[wanton thistle]

Im assuming you mean soil moisture senseor. Dont get the ones that have two probes, those will corrode eventually. Instead get the capacitive ones.

[static flare]

Nearly accidentally bought 100 of a chip

Which, mind you, not a terrible purchase, as it's only $20USD

But I don't exactly need 100 of them

[static flare]

oh no i forgot to change the number when i went back to purchase it and now I've actually spent $30USD total (including shipping) on 100 ICs

[wanton thistle]

what ICs?

[tardy badger]

A cheap risc-v chip?

[static flare]

SL2.1A

[wanton thistle]

why not cancel your order?

[static flare]

shrugs Can't really be bothered, I'll just have more chips than I originally needed

Might design a cheap USB hub and 3D print a case or something as a gift for people, or even just sell it, cause it'll end up being fairly cheap to make anyhow

[tardy badger]

I’ve been thinking about making a USB-C super speed hub

[spice moss]

https://tenor.com/view/superman-superhero-gif-26117056

some could make design like that

the super speed hub sounds awesome

[tardy badger]

All my USB-C hubs are not supportive of SS, they just deliver USB HS

I could add an Ethernet controller and also get Ethernet on the hub

[spice moss]

ESP to hub?

[static flare]

These are, unfortunately, by name, 2.1 hubs

[tardy badger]

Yup

I’d get a dedicated USB3.1 to ETH PHY controller IC

Like this one for instance https://www.digikey.com/en/products/detail/LAN7801-I%2F9JX/7164764

[static flare]

oof $10 a chip

I mean, it seems worth it

At least the SL2.1A is decently hand solderable

[tardy badger]

gigabit eth would definitely be worth it for a SS hub

I wish I had the financial leverage to get them at a decent price

but then i'd have to sell a few hundred thousand units xD

[static flare]

I bet, but I could buy ~41 SL2.1A's for that price?

[static flare]

Huh.

PCBs are actually really cheap right now

At least from JLCPCB

I can buy 30 of this one design, and it won't cost me anything but shipping

[tardy badger]

Yeah, I have a 6L board I want to try but I need to fix a via and remove the castellated holes (which aren’t used anyway) so I can get it for $18 shipped with a stencil lol

Change my 8/4mil via/pad via to 8/4.3mil via/pad

[gusty torrent]

And JLCPCB's "slow" shipping is actually pretty fast. I get boards on my doorstep in 6 days from ordering with the cheapest shipping option available.

[static flare]

just made a breakout board with all the passives needed for the sl2.1a

theoretically, you could use it as a hub, if you soldered cables to it

plus it's about 2x2cm total

well, 1.65x2.03cm

oh wow the discount also includes shipping

I am getting 30 boards, all shipped to me, for about $1.50USD ($2.23AUD)

[tardy badger]

wow, not bad

[static flare]

Correction, $1.50AUD now, cause I decided to use my card instead of PayPal

[tardy badger]

$19.64 USD for my 6L BGA board

with a stencil

[static flare]

It would have cost less but they legally couldn't in order to ship it to me

[tardy badger]

the PCB itself is $3.54 for 5 so pretty good really

[static flare]

6 Layer BGA? woah that's good

[tardy badger]

yeah, filled and capped via too

[static flare]

Yeah, I heard they did that for free for 6L boards now

[tardy badger]

yeah, pretty awesome. you pay like $2 extra for it to happen on 4L boards

[static flare]

the wonders of PCB manufacturing in this day and age

[tardy badger]

which makes doing BGA more reasonable, especially multilayer PCBs

they don't do blind/buried yet. but it's just a matter of time before it's available cheaply

rather than $400+ for them lol..

[static flare]

I'm glad I'll have a dropin USB hub module when I need it now

And then 70 more chips to play with

[tardy badger]

sounds pretty cool

[tardy badger]

Okay, my 6L board is in production. I’m nervous about the via for the reset pin as it’s really close clearance wise. It has to violate DRC to be placed

[flint musk]

I need something like a raspberry pi but more powerful, but still cheap that I can run as a server (for nextcloud, Jenkins, and some personal projects)

I currently have an RPI 3, but it's constantly getting overloaded

I'm thinking about maybe an old Optiplex, which also gives me a decent upgrade path if I want to

[tardy badger]

You might look at some of the RISC-V SBCs

There are some pretty powerful ones

[flint musk]

Well I'd prefer to move away from SBCs

[tardy badger]

Ah, finding something small and module might be difficult

Not impossible, but probably a little pricy

[tardy badger]

FedEx: “your box hasn’t even left Minnesota”
Me: cries in lost time off

[thick wind]

NUCs and miniPCs are nice if you don’t need too much external storage?

[ebon dew]

even an old optiplex would do better as a server than a pi 3 sure if you're not playing with embedded systems and need gpio.

the new NUC's are surprisingly powerful, don't count out ITX if you want a small form factor

anything with m.2 can really help with smaller form factors and m.2 is wicked fast.

if it's only for personal lab projects m.2 is to about 2TB affordably now, plenty for any lab setup.

m.2 is the new standard for any OS drive. NVME is amazing.

[tardy badger]

I do love me some m.2 drives

[lusty fossil]

I built a machine recently with a 980 EVO. Boy is it zippy

[fierce prawn]

Then pi4?

[dusty citrus]

is there a name for those connectors/mechanism that lock and unlock the thing that you do insert by pushing?

[dusty citrus]

like sd card trails locked if pushed
unlocked if pushed back

[ebon dew]

i think when it comes to sd cards they go by push/push or push/pull to indicate if there's a spring mechanism.

as for the actual lock mechanism, perhaps a detent?

[dusty citrus]

I think of that as 'a latch' and the type of action of the latch is a subcategory of 'latch'.

https://boingboing.net/2020/12/14/visual-explainer-of-how-a-push-latch-mechanism-works.html

[lusty fossil]

Well. I made it 3 years without getting covid, but I am no longer one of the elite.

[fierce prawn]

Is a rotary encoder for keyboard good

[lusty fossil]

Depends on what you want to do and what features you want to implement

[crystal ore]

Are you making a gigantic keyboard dial like a rotary phone?

[fierce prawn]

No
One key and one encoder

Fell good?

[late fulcrum]

I have one of the Keychron keyboards with a rotary encoder on it, I find it handy

[wooden valley]

I didnt end up ordering one, im looking to make a raspberry pi pico keyboard

[fierce prawn]

But would be a one key keyboard with one encoder usefull

[late fulcrum]

I don't know, but I'd guess there could be use cases for which such a peripheral would be handy

[crystal ore]

It's basically a paddle-wheel joystick.

[wooden schooner]

How might I go about finding the approx current draw of this handheld vacuum (without buying it first)?
https://www.ryobitools.com/products/details/33287200290
I don't see any documentation about that, would appreciate advice on where to look (including unofficial sources).

[crystal ore]

The main thing would be to try to find out how long it runs on a given type of battery.

[fierce prawn]

how many people can write code and make mininal bugs at once

[tardy badger]

i'd say 4-5 tops if working on the same repository but different feature branches. only add ons though, breaking changes could get really confusing and messy.

though optimal is 2-3 people I'd say

for a larger project, probably 5-7 people with no crossover except for maybe someone making the install package.

[fierce prawn]

hmm is it normal that i write a tons of code and in the end it only needs some json ref change

cz i have it happen to me on the project i am working on

its a auth session system

[raw mirage]

which came first, Xmas or Xtal?

[fierce prawn]

xmas

[wanton thistle]

only amazon review I can find says 10 minutes

but..Id take that with a grain of salt

too many factors, is it constantly sucking up dirt? Or idle just sitting?

[fierce prawn]

or just sucking air in and out

[wanton thistle]

It looks like anywhere between 10 and 15 minutes is a safe bet. The reviewers dont list the batteries they have, but Ryobi has 2000mAh and 4000mAh. Im assuming they are using the 2000mAh batteries

[wooden schooner]

they've also got a 9Ah battery ($155 but boy it's purdy)

iirc there is a bundle that includes both the vacuum and the battery and it comes with one of the lower capacities

[lusty fossil]

Where do I go to post an adafruit job? I can only see posts for seekers.

[wanton thistle]

that sounds like the 40V one. I know because I have the mower lol. The 3rd party batteries are less expensive 🤔

[wooden schooner]

nope this is an 18V, 9Ah battery, my partner has one https://www.ryobitools.com/products/details/33287174454

they ain't kiddin around with that one, it can even power big tools

ah, the specs table for the vacuum on amazon is more extensive than what's available on the manufacturer website and in the owner's manual (why...), looks like that hand vac is specked for 120W https://www.amazon.com/RYOBI-Cordless-Multi-Surface-Handheld-Vacuum/dp/B0B2FRY36B/

[wooden schooner]

didn't realize there are cheaper aftermarket batteries compatible with the ryobi system, thanks for bringing that to my attention!

[wanton thistle]

thatsa big boi

[wooden schooner]

yeah it's huge lol

[wanton thistle]

https://www.amazon.com/dp/B07LGVKTM5/?coliid=I3NCKO7MD7YYPT&colid=19EDP5ZLUUA98&psc=1&ref_=lv_ov_lig_dp_it
Yea you just gotta look. This one is for my mower. I havent bought it yet but I do wonder if I can truly DIY it legit cells

[lusty fossil]

Milwaukee has some 72V things

Wild

Like a saw for asphalt

[wooden schooner]

is there meaningful variability in quality among different brands of lithium battery for hand tools?

(complete noob question)

[wanton thistle]

and yet the power wheels still use 12V lead acid batteries. One of these days I'll find an old power wheels and convert it lol

[wanton thistle]

Without looking under the hood, probably. GOOD 18650 batteries with a high discharge can go from $5 to $8 each. Cheap ones are under that (unless you get a good sale)

So yea, you do get what you pay for

and thats the caveat. Im sure the Ryobi batteries are legit. After market? not so sure

[wooden schooner]

yeah got it

might also consider used ryobi ones

[wanton thistle]

not a bad idea. If you have the means to, Id look into replacing the cells.

[wooden schooner]

there are a bunch of aftermarket ones that have really good ratings on amazon - 4.5 stars, 1000+ reviews

doesn't necessarily mean they're good, i know

[wanton thistle]

I was gonna say, unless they were tested and verified, you dont know

Could be that 10 out of every 100 are bad. But with legit 186500 sellers, you know what you are getting

And Ive seen some cheaper cells on sale for $3 that were pretty good. Just have to look at reviews

[wooden schooner]

what does "tested and verified" mean here? i assume it's not possible to test individual units to predict longevity, you need to audit the manufacturing process and look at percentage defects over a large sample?

[gusty torrent]

And never buy 18650s with Fire or Sure in the brand name because you can be sure they'll catch on fire.

[late fulcrum]

Capacity claims for over 3.2Ah are also to be suspect.

[late fulcrum]

I'm planning on using lead-acid for my electric hovercraft.

[wooden schooner]

where'd you get the 3.2Ah number? is there something about the battery chemistry that makes it a soft limit?

[late fulcrum]

The highest I've seen from reputable manufacturers so far is 3.1Ah, so I added a little buffer in case they've improved somewhat. The sketchy sellers claim all sorts of numbers, I've even seen 9999mAh listed for an 18650, not likely, and of course the "clock strikes 13" effect applies.

[lusty fossil]

What do the 6 Ah batteries tool makers sell have in them?

[late fulcrum]

Likely a series-parallel arrangement

Like this 6.6Ah pack, which is just 3 2.2Ah cells in parallel https://www.adafruit.com/product/353

[wooden schooner]

the power tool batteries don't say they're not just a bunch of cells in parallel, right?

[lusty fossil]

They are that afaik

[late fulcrum]

They normally give a voltage and current like this 18V 6Ah pack. Given the chemistry, you can often make a good guess as to the internal arrangement. Since it says it's a lithium battery, I'd guess a 5S2P or 5S3P arrangement.

[wooden schooner]

yep that makes sense

so why the need to be suspicious?

[late fulcrum]

We were talking about individual 18650 cells, not entire battery packs. For individual cells of that size, I'm suspicious of unrealistic capacity claims.

[wooden schooner]

oh for sure

didn't realize that comment was in the context of individual cells

got it now yeah

[late fulcrum]

That said, I wouldn't buy lithium cells from amazon unless I was going camping and needed a fire starter.

[wooden schooner]

meaning no-name brands are dangerous, yeah that makes sense

[late fulcrum]

And given amazon's "equivalent merchandise" policy, even if you buy a nice unit from a reputable seller, even one you've gotten good units from before, you can still get an "equivalent" counterfeit from some other seller.

[wooden schooner]

yeah that is absolute garbage

and should be illegal

[late fulcrum]

We're working on it.

[wooden schooner]

any links i can look at?

[late fulcrum]

https://www.cnn.com/2021/10/15/business/amazon-elizabeth-warren/index.html

[wooden schooner]

oh heck yeah

[late fulcrum]

Torque Test Channel tried out some of amazon's house brand power tools and utterly excoriated them (the Wal*Mart and Harbor Freight offerings clobbered them, and the real brands leave them in the dust)

[wooden schooner]

i'd say amazon is allowed to have a low quality house brand, it's just, like, almost everything else they do that should be illegal

[late fulcrum]

Agreed.

[lusty fossil]

Is the red milwaukee?

[late fulcrum]

Yeah, the red is Milwaukee, the blue is the weakest one they had previously tried (Bosch Freak), and the green is the amazon Denali.

[lusty fossil]

Makes me feel good about my choice in tools

[late fulcrum]

"The person who buys quality tools only cries once."

Several of my friends have the usual $60-90 hammer drills from big-box stores. I splashed out $190 for a Hitachi rotary hammer. The difference is like night and day, the Hitachi pokes holes in big-aggregate poured concrete walls like butter. I often spend more time taking the tool out of the carrying case than I do actually drilling holes.

[wooden schooner]

my partner is good at spotting good stuff on craigslist. Apparently, in many cases older tools are just better because the big brands had not yet moved to cheaper materials. Craftsman clamps from the 50s were all-metal whereas today's are ABS, etc.

[late fulcrum]

I like to haunt auctions for similar reasons.

I think this is the review that made up my mind on the Hitachi. https://www.jlconline.com/tools/fastening-tools/power-tools/tool-test-compact-rotary-hammers_o

[lusty fossil]

I'm a big fan of Milwaukee, not because they are the best of the big box brand at EVERY tool, but because they are among the best at most and the best at a good number

Also having one kind of battery is a true luxury

[wooden schooner]

that there sounds like a description of Ryobi

[late fulcrum]

I like the older Milwaukee plug-in tools (the Hitachi is also a plug-in). I only use battery operated for smaller stuff.

[wooden schooner]

in general it seems that Home Depot's store brand is a very good match to the big players in, like, good-quality layperson equipment

I filled my apartment with HD (Commercial Electric) ceiling panels and they're nice

oh I thought Milwaukee was a HD brand too, apparently it's not(?)

[lusty fossil]

No Milwaukee is very much its own thing

[wooden schooner]

might have been mixing them up with Husky

[lusty fossil]

Yeah they have a similar color scheme

[wooden schooner]

yep what else do you need in a company

[lusty fossil]

I have some husky work bags, really nice quality, especially for the price.

[wooden schooner]

these bins in particular i like a lot https://www.homedepot.com/p/Husky-Stackable-9-in-Click-Bin-Gray-4-Pack-17193661/202931355
they're like the usual stacking bins, but rather than sacrifice storage volume (vertical space) to stack, they attach via click-in tabs. (the handle i haven't found to work very well, but it's a good concept)

[late fulcrum]

While I like the fancy expensive ones like the Festool Systainer ones, I end up using a lot of Akro-Mils bins on ordinary shelving, and portable cases by the folks at Plano Molding.

[lusty fossil]

One day? One day I will own a 3 car garage with no cars and only Hilti power tools.

[wooden schooner]

I've mostly resigned myself to the fact that I'll always be looking for a better storage system

[lusty fossil]

My triple board certified surgeon spouse will pay for it all, of course.

[wooden schooner]

one cannot fully put to bed the question "But what if I get more stuff"

[late fulcrum]

A friend of mine didn't end up marrying a surgeon exactly, but an anesthesiologist. Apparently a fairly well known one, that hospitals get in bidding wars for. They were asked to buy a more expensive car, just for show.

[lusty fossil]

Yeah anesthesiologists are paid very well

[wooden schooner]

who is "they" here?

[lusty fossil]

I assume the couple

[late fulcrum]

They here is my friend. Their anesthesiologist spouse asked them to go buy an expensive car

[lusty fossil]

Oh

My b

[wooden schooner]

oh so it wasn't like "put up this money before i marry you" but rather "we're rich so yolo, please pick out a toy for us"

[late fulcrum]

Right

[wooden schooner]

at first i thought you were saying the hospital bought the spouse a car as a bribe to work there

i guess signing bonuses can easily get as big as car-price level for high paying professions

[late fulcrum]

Way bigger than that, apparently.

[dusty citrus]

at 1:59 https://www.youtube.com/watch?v=pBueWfzb7P0 ; how did they cut the inside without making a cut coming from the corners to the center? as I see they use a thin wire to cut through metal as they do with styrofoam

[rapid geode]

2 separate parts.

[cursive swan]

What's a good small colour screen for making an analogue clock?

[rapid geode]

define small

adafruit has 1.3 and 1.5 inch square IPS screen good for watch sized things

[cursive swan]

That sounds good

It's too many a bedside/desk clock

[rapid geode]

ah

[cursive swan]

Ah you mean like

https://shop.pimoroni.com/products/2-0-320x240-color-ips-tft-display-with-microsd-card-breakout?variant=29413854249043

[rapid geode]

thats a bigger one bit yes, waveshare also has larger screens, 2.8 and 3.5" with HDMI controllers

but they cost more

[cursive swan]

Do Adafruit libraries work on Waveshare screens?

[rapid geode]

its hdmi, no library. you use them with raspberry pi or PC

[cursive swan]

So this looks like the graphics library:

https://github.com/adafruit/Adafruit_ILI9341

Oh these scenes are HDMI?!

[rapid geode]

the waveshare ones yes. the adafruit smaller ones and the pimarioni are SPI

[cursive swan]

I think SPI would be better for my small project.

[rapid geode]

https://www.adafruit.com/product/3787

[cursive swan]

I'm trying to find documentation. Specifically on got to draw a line.

[rapid geode]

https://www.adafruit.com/product/4313

those 2 are the popular small ones

[cursive swan]

That looks great

[rapid geode]

the 1.3 is used on the adafruit clue, so there should be many examples of its use

[cursive swan]

I can't find the documentation

Is there a library in CircuitPython instead of Arduino code?

[rapid geode]

clue is circuit python, but these screens predate that and are used with arduino

[wooden valley]

how can I solder a breadboard button to a wire?

[cursive swan]

How do you mean?

You would need wire and soldering iron and solder

[cursive swan]

Thanks. Are there any SPI screens that have a CircuitPython library?

[wooden valley]

yea but the pin would not grasp the solder

[cursive swan]

Can you show a photo of the things you want to connect?

To give a better idea how to advise you

[late fulcrum]

There are round LCD screens as well, but they're more expensive and difficult to find.

[cursive swan]

I want a square screen ideally.

[late fulcrum]

Ah, those are easier to find and less expensive.

[tardy badger]

Dang, 4 transit days without a scan. Minnesota FedEx facilities must be super backed up. Looks like I won’t be finishing this Watch prototype anytime soon 🥲

FedEx customer service told me yesterday that the trailer my package is on hasn’t even left the facility. And I won’t get a shipment update until it does.

It’s not the end of the world, but I am filled with the sad because I was really looking forward to spending my week off building the new watch. sigh

[burnt tendon]

FedEx has lost packages sent to me for substantial periods of time.

Also dead bodies, but that's different.

[late fulcrum]

There is the chance that FedEx simply dumped their excess into the postal system (again), and it will re-appear in your mailbox

lmaooooo

[cursive swan]

What is that

[wooden schooner]

oh this might be a good place to ask: for a gift, I'm looking for a nice wood keyboard. "Nice" like the Keyboardio Model 100 which has a beautiful walnut casing, but not split, and might have some other ergonomic requirements. https://www.indiegogo.com/projects/the-keyboardio-model-100--4/ Anyone know of good places to look?

[lusty fossil]

Hmmm

Etsy?

Tindie?

[whole jacinth]

the Model 100 has a center bar that optionally holds the halves together (that's how i usually use mine), but i don't know if that's still too "split" for the ergonomics of your intended user

[wooden schooner]

oh nice gtk. and you like yours?

[whole jacinth]

i like it a lot, actually. excellent key feel and sound, and highly customizable. (disclosure: i help out with the firmware)

if you remember the really old Apple Macintosh keyboards, like the pre-ADB ones with the phone-style modular plugs, it's a very similar sound and feel (the Model 100 "Silent Tactile" key switch option, that is. i haven't tried the others yet.)

[wooden schooner]

ok, the recipient says they're too picky about keyboards for me to be able to realistically predict what they'll want, so we'll probably do a bunch of try before you buys

thanks for the tips tho!

[tardy badger]

I tell ya, perhaps the biggest struggle with parenting young children is teaching social and conversational awareness. Like being able to talk about things you’re interested in, but also learning that not everyone wants to hear about the same things over and over, all day long.

Currently the goal is to teach my son that it’s great to be interested in things and wanting to talk about them (in this case, he love to talk about Pokémon). But trying to teach him that talking about it the right amount of time to not become annoying. That’s the hard part lol..

Basically morning till bed is all Pokémon talk lol

[lusty fossil]

Tbh that's my daily as an adult

[tardy badger]

Lol

I love Pokémon and I indulge it, but he’s wanting to learn every mm of it and sometimes I’m just maxed out and it drives me batty lol

[lusty fossil]

You can't really do this with a kid, but this is why I taught my dog "go away".

[tardy badger]

Lol

[wooden schooner]

Omg

My dog? No she hates it but I have to buy her food so I have to work sometimes

She gives me the most hurt, sullen looks

pokemon/videogames knowledge is totally useless

I donno, the joy that was brought to you wasn't useless

Like that had to have had a positive effect on a growing mind

[ebon dew]

feel like i wasted a lot of my life on video games... games which don't even exist anymore. if i'd gotten into engineering earlier i'd still have the PCB's and software to show for it.

this is true, and the distraction it gives kids so parents can have some peace and quiet.

[hard estuary]

I don't regret it, I was a big gamer in the late 90s. That taught me how to upgrade my PC hardware, which then led me Linux, which led to contributing to open source. 🙂

[ebon dew]

the time spent working on the physical build pales in comparison to time spent gaming.

though gaming also lead me into game server administration, then web server administration, then virtual machines, virtual hosting, vpn, 3d modeling, music, etc...

gaming is a gateway drug to computers

[tardy badger]

Gaming ultimately led me to many of the friends I have today, and to this community in general

It was sort of round about, but I also still enjoy gaming too. It’s a way to spend time with my brothers and nephew who live across the country

[hard estuary]

Same - I just finished all 4 Halo games with my youngest, who is a teenager and normally wants nothing to do with his parents

[ebon dew]

i have like 3K+ hours logged in quake, did i really need to play that much to get good at a game that ultimately has no place on a resume

[dusty citrus]

I'd liked to learned other stuff, but I was quite isolated/limited to say at least;
gaming in the other hand... it was easier to acquire knowledge and I had more freedom within the game

[ebon dew]

as you get older the question of how you spend your time is yeah... but can you put that on a resume

[dusty citrus]

although in the "real world" it's totally useless stuff

[ebon dew]

i think the pandemic is an exception... when playing in a park could get you arrested or fined... video games became an acceptable outlet (in the 1990's every shooting was blamed on FPS games)

i feel much more productive today working on pcb designs, 3d modeling, 3d printing, and general making stuff than i ever did with video games. it's far more rewarding.

wish adafruit could tag your account with real life achievements like "made your first LED blink in Arduino"

printables has stuff like that for 3d models and it honestly just makes me want to make more to see what other achievements are in there

user profiles, user pages, user achievements, merit badges, i think will be my adafruit wish for 2023

[late fulcrum]

They do offer physical skill badges, but virtual ones would be fun

[ebon dew]

i was a boy scout, so achievement hunting, badges, acknowledgment of skills learned and applied is kind of in my dna now. perhaps why many new games that offer achievements have been so successful. Adafruit could tap into that better for scout programs too.

like tape out for example, i have no desire to learn how to do controller design, but if adafruit had a badge for it, i'd probably dive into it. provide incentives to learn. i'm not for monetizing NFT's but could offer them as NFT's?

or just icons next to a profile name on adafruit user profile would be just as good. just an idea.

[late fulcrum]

It would be tricky for the "gotta catch 'em all" types, when some of the tasks don't align with our interests/abilities

[ebon dew]

yes but you'll still learn new things and have a deeper understanding of electronics even if it's not your particular interest.

[late fulcrum]

Mmm, only if they're particularly well-chosen

[wooden schooner]

Judging kids' choice of survival mechanism (video games) by its performance on parent-oriented metrics ("return on investment") is fundamentally backwards. They were not empowered to have a real say in the terms of the deal.

[late fulcrum]

My survival mechanism (repairing old oscilloscopes) arguably had a poor return on investment (I now have a pile of working, but obsolete, oscilloscopes).

[tardy badger]

I played video games which kind of disposed me towards stem education

[lost geode]

Anyone know where to get quick connectors for + and - wires?

[late fulcrum]

Are you looking for push-on connectors, like for the input terminals for speakers, or some other +/- wiring?

[lost geode]

No these for connecting and disconnecting for cosplay travel purposes

[late fulcrum]

There are several kinds of connectors available that can do so.

The usual parameters are things like how much power you need to convey, how hard the connectors are to attach and remove, how easily they fall disconnected, size, ease of assembly, cost, etc.

[lost geode]

These look good

[late fulcrum]

Those are more for just connecting bare wires than plugging a pair of connectors together, but they would likely work. AdaFruit offers some similar ones like https://www.adafruit.com/product/5618

[tardy badger]

The Adafruit ones look better imho

The colors really pop

[fierce prawn]

Mine do have a good return
My latest project
https://rv.darren.ee.eu.org/dash/

[late fulcrum]

Making websites?

[rapid geode]

i invest in things guaranteed to not make any money... 😛

but thats not really true. all the knowledge i gain from it lets me a have a good paying job. it is indirect.

[wanton thistle]

So Im taking my car to the repair shop (the $tealership) and Im wondering: is it worth telling them what I suspect the issue is? I mean its deductive reasoning based on the noise and a few YT videos I watched, or just let it be and let them figure it out?

[hasty wedge]

bad apple in a DAW

[whole jacinth]

does it also play the music?

[thick wind]

Definitely provide any observations of issues you’ve encountered. Whether or not you want to sneak your own hypothesis in probably matters very little, if at all.

Especially at a dealership, anyways. If you’re talking directly with the mechanic at a smaller shop, it probably makes a bigger difference.

[wanton thistle]

True. I do wonder how much gets relayed from the service person to the tech at times

[ebon dew]

@wanton thistle Tell the service writer exactly what you think. It's absolutely helpful to point them to where you think the culprit is. Just do not ever attempt to include the sound that things are making by sounding them out.

Use descriptive words like moaning, groaning, crackling, ticking, clanking, humming, etc.. use adjectives.

If you submit a hypothesis to what the culprit might be then explain what lead you to that conclusion. When you do A, B happens.

Helping a tech find a culprit faster means less service time, less cost to you potentially. Often times the real culprit could be deeper and what you think the culprit is, is just another symptom, and the real culprit is a bit deeper... but that's what diagnostics is for.

[wooden schooner]

This reminds me, the Julia REPL will tab-complete a LaTeX command. A second tab will substitute the corresponding Unicode symbol. Several such symbols have built-in meanings, e.g. the infix predicate ∈ for membership in a collection.

People always say "that's not impressive, haven't you seen APL," but (i) basically no, and (ii) I still find it notable, given that Julia is in many ways designed to appeal to Python users.

[late fulcrum]

A quicker way to input common Unicode characters than U+2abc would be nice.

[gusty torrent]

I did a short APL course in university. People taking it got the right to kick people off the 3270s with APL character sets.

But by a couple years later everyone was using 3270 emulation stuff.

[fierce prawn]

Should I buy a string of Neopixel even if I only need one

[fierce prawn]

@late fulcrum

[spice zealot]

Hey! I want to make ornithopter ( bird drone ) with swarm ( multiple drone ) show which controller i should use ?

[fickle viper]

Hey there, I'm currently working on a project where I'm trying to sell addressable LED-Strips using the Adafruit NeoPixel Library. Does anyone know how to take two RGB(W) inputs and make a gradient with that?

[late fulcrum]

You could get a 5 pack https://www.adafruit.com/product/1938

[late fulcrum]

Linear interpolation, basically.

[fickle viper]

can you refer me to a code example?

[late fulcrum]

I don't have one handy, but it's basic linear algebra. For each channel (red, green, blue, and white if you're using it), use the endpoints to compute a line formula (slope and intercept), using the starting and ending NeoPixel indices as the X value, then for each intermediate pixel, solve those equations for the pixels' indices.

Alternatively, you could use something like Arduino's map() function, but since that does integer math, it can yield poorer results than a floating point calculation.

[fickle viper]

alright, i'll try and figure that out with my 9th grade algebra skills and my 2 months c++ coding experience 🥲

[late fulcrum]

Let us know if you have issues, I can try to bang out some example code if need be

[fickle viper]

i just don't know where to start, that's my problem

but i'll give it a shot and try and learn from it, don't help me just yet

[fierce prawn]

Great material?

[tardy badger]

FedEx: nothing. Nothing. Nothing. “YOUR PACKAGE IS OUT FOR DELIVERY”
Me: 🤪

Finally getting my parts to finish the current watch prototype

[late fulcrum]

Usually the next one I get is "delivery attempt failed, no one was home"

[fierce prawn]

Is this material thick enough
It's thicker that normal cardboard and from a Ikea furniture box

[late fulcrum]

Thick enough ... for what?

[tardy badger]

To be thick as thieves

Lol jk

[whole jacinth]

it depends on what you’re going to use it for. it looks like a honeycomb-like cardboard instead of corrugated? my guess is it might be good at one-time shock absorption, but the inner layer might buckle above a certain load, weakening it more than corrugated

[dusty citrus]

huh I'd wish to be working in a manufacturing center of sorts
so I don't need to wait months to get parts

that said
does anyone know any live quoting website/manufacturing center that makes photochemical etching or really fine laser manufacturing?

[tardy badger]

What’s the application?

Or end product?

Depending on what you’re making, it might not be possible to work without a broker.

Fotofab looks to be the most popular photochemical etching company but a quick search shows that most require you contact them for a quote

[dusty carbon]

hey

Random question, I have a habit of testing LEDs before I use them in a project but I have had my first bad resistor

Is it common to test resistors? I think I may in future

[late fulcrum]

Resistors are simple parts and (aside from decades old carbon composition ones) fairly reliable. But any part can fail or be defective. I generally don't test resistors, but when circuits don't work the way I expect, I start measuring lots of things.

[dusty carbon]

After soldering a project together I had a LED burn out. After checking the resistor appears to be doing absolutely nothing 3.3 volts happily passing through while an identical resistor reduces the voltage to 2.7v

[late fulcrum]

A resistor failed shorted instead of open? That's a new one for me, and I can see how that would fry an LED.

[dusty carbon]

They are simple parts which is why I generally trust them

yeah the resistor is providing no resistance. A new error for me. Like you I spent a lot of time measuring the circuit. Presumed I must have bridged by mistake somewhere, but nothing.

o well I better remove the LED and Resistor and try again

[warm crypt]

@dusty carbon for what it is worth I try and test each part before placing them on the project. I.just did a new amiga motherboard and it work from the first startup......Best Dr. Hann Ph.d

[dusty carbon]

Would have been a good idea. I grabbed a new resistor rather than the one I used when testing on breadboards. Lesson learnt

[fierce prawn]

Can someone tell me why adafruit promised to not sell blinking Christmas tree

[fierce prawn]

The promise page is a broken link

[quiet harness]

Has anyone seen any DIY audiophile communities that make their own headsets (headphone/microphone combos)? I'm trying to find a headset that isn't crazy huge, wireless, and guarantees good microphone quality, and isn't $100 and doesn't have proprietary software requirements for a just a stinking mute button and battery capacity.

I'm just about to the point of just making it myself. I'm others here can relate with the "I'll do it myself part" 😂

[crystal ore]

Not for consumer electronics... Anything you build will be much crappier and costlier than mass-produced versions, I'd expect.

[quiet harness]

Hmm ok, I was hoping there was a community kind of like the custom keyboard community. My current solution is to use logitech g733 for headphones (or any bluetooth headphones really) but the mic is terrible. So using a $50 condenser mic fixes that. It's an ok solution but I can't get up and walk away.

headset microphones are so hit or miss and I didn't know my mic was so bad until I listened to a recording of it and it has SUPER bad hissing that I wouldn't want to listen to for an hour during a meeting

Mod mic wireless may be the next best thing. But now that's a second thing to charge, second USB dongle, and second set of software to manage.

[lusty fossil]

IME custom keyboards are also quite a bit more expensive than a mass produced model of the same quality

[thick wind]

You’re not going to get studio level quality from a wireless gaming headset. If your use case is something like streaming, for example, a lapel mic (lavalier) is a more common.
That being said, I’ve had some reasonable audio quality from some gaming headsets. Not sure how good you need, but some of the more expensive gaming headsets have good enough mics for meetings.

[quiet harness]

I guess I should clarify what I mean by quality microphone. Good enough for clear meetings where the focus is voice, but I'm not targeting content creation for something like youtube consumption. Sometimes I make recorded videos for work but for those specific use cases I can grab a quality mic. To me quality would be elgato wave 3. Consumer level better than crunchy.

Most of the problem has been consistency where a $200 wireless headset that my company purchased for us is trash, but suddenly the built in microphone on a laptop sounds crystal clear. My condenser USB microphone is consistently good. Maybe because it's wired and has super bog standard drivers.

Part of my inspiration for this is the custom microphone from DIY perks.
https://www.youtube.com/watch?v=LoQu3XXIayc

The audio quality for the headphones I'm not too concerned with. I'm not actually an audiophile by any means. I'm just looking for a consistent quality device that works across machines but still wireless I guess.

The logitech G733 even has a 3.5mm headphone jack input for detachable microphone, but I don't have any other microphones to test if the bad sound is from the dynamic mic capsule or wireless compression.

[fair summit]

maybe a good lavalier mic?

[quiet harness]

Possibly. I haven't dug into those too much, so I don't know about how the actual capture or transmission works. There's probably a lot more options in that space than the antlion wireless mic. That also solves the issue where the antlion wireless mic needs to mount to large circumoral headphones

Hmm, only a 10 minute googling but it's seems like you can either buy garbage for $30 or spend $200 and up for lavaliers.

Just seems odd to me. It's just a microphone and an ADC. The wireless transmission is the hardest part but I would think bluetooth from an ESP device would have plenty of bandwidth for it. Throw a standard LiPo cell + chargeer in and you've got yourself a wireless mic...

[thick wind]

If your headset has 3.5mm mic in port, you could just consider a wired lapel mic with a 3.5mm jack?

[fair summit]

i meant a lapel mic

that is, a wired lavalier, not a wireless. those $20 ones

I don't think the cheaper ones are necesasrily garbage

[quiet harness]

There I go using subjective terms again. What I meant by garbage is they're no better than in ear true wireless headphones that include microphones.

[late fulcrum]

I have a $10 Plantronics gaming headset that has good audio, but it isn't wireless.

[quiet harness]

Ah I see. Along with what Hem said I think that might be the best option. Headphones are just the one thing I can't do wired. It's definitely better, but the cord dragging on me, even with a clip, bothers me a lot. And often I need to get up to do stuff during a meeting.

[fair summit]

the amazon g733 reviews say the mic isn't very good. But there are others: https://www.soundguys.com/best-gaming-headsets-with-good-microphones-28391/

I wonder if one should not look just for "gaming" headsets. e.g. check out sweetwater.com or some more audio-ish review

[wooden schooner]

Yeah I got the V-Moda BoomPro (from sweetwater incidentally) and am fine with it

[fair summit]

my brief trials of gaming headsets at microcenter was that I didn't like the headphone sound in most of them

[wooden schooner]

It goes inline before any headphone that takes a stereo input

[quiet harness]

Right, gaming headsets just tend to tick most of the boxes. I bought a pair of audio technicas for like $60. And if the lapel microphone works that's like an extra $10. Individually these things are cheap, purpose built, and good at they're job. But if you tac on wireless and put them into the same device, suddenly you're into about the $200 range, and getting inconsistent audio.

[wooden schooner]

(I am extremely suspicious of wireless anything, especially Bluetooth with its "headset" profile that always ends up being the fallback)

[quiet harness]

That's why I was asking here about a DIY headphone community. Building my own macropad was refreshing. It does exactly what I need it to do without proprietary elgato software.

[quiet harness]

I'm always paranoid when my bluetooth headsets fall into the crunchy headset mode. They sound so bad.

That's why I'm OK with USB receivers. But the logitech gaming software is equally terrible.

[fair summit]

https://www.nytimes.com/wirecutter/reviews/best-gaming-headset/ more reviews

teh comments are probably worth reading too

[wooden schooner]

I'm not aware of open source Bluetooth audio that competes with the best proprietary codecs, or anywhere near it

[quiet harness]

The codec is where my inexperience shows. Idk how much of the problem is the hardware or USB drivers/wireless compression.

Oh yea and the RGB lights on gaming headsets drive me crazy. Waste of battery and THEY REFLECT ON GLASSES IN YOUR PERIPHERALS!!! Who thought that was a good idea?

[wooden schooner]

Usually the latter unless your headset is the utmost crap, is my understanding

Not an expert by any means tho

[quiet harness]

No worries, this is a maker discord server, not an audio/sound discord. I have a very niche problem that probably wouldn't bother most people enough to look into solutions.

[wooden schooner]

There's a #help-with-audio channel

[quiet harness]

The lapels are even cheap enough I can shorten the cable and wire in the mute button. One other problem with the logitech headsets, while I'm ranting 😅 , is that you only get battery percentage readout with the logitech software installed. So when I want to use it on another maching (work laptop) I don't get basic features anymore.

Don't mind me while I go spend the next 2 years building my own headset when I could have solved the problem with a bit more research and smaller amount of money on an off the shelf solution

[wooden schooner]

Don't forget capital. Not fair to compare your own efforts to those of a corporation without taking into account their huge cash reserves

[quiet harness]

I think that washes out with how corporations have to design to specific markets, design injection molds, source parts en mass, develop software, etc. etc. I understand why headsets cost what they do. I just don't understand why microphone quality is so inconsistent unless you buy a purpose built one.

[wooden schooner]

Oh I mean they have to do more things but I'd say it nowhere near washes out

[quiet harness]

Lol ElectroBOOM saved me some time
https://www.youtube.com/watch?v=fO8pPjlFtNw

Ok figured it out, it's the logitech wireless USB interface that's compressing it. I remembered I had a generic USB to 3.5mm ADC unit I got off amazon a while ago. I plugged in the microphone directly, wired essentially. And it's WAY WAY better sounding. It's not the best microphone in the world but I have to blame logitech again.

[tardy badger]

Working on an EPD board but I can’t seem to get the display to update. le sigh tried both the ssd1608 and the UC8151D (the claimed driver on the product page for the display I bought)

[late fulcrum]

Does it reply when queried?

[tardy badger]

Well, it only has data out, so you can’t read back the display

I even probed the diodes for the high voltage (supposed to get up to 25V or something like that) when updating and I didn’t see it go anywhere. Stayed at 0V

Probed the FPC connector to make sure it was actually soldered to the board and it was

Microscope inspection of the RP2040 shows good joints so I’m at a loss for the evening

[late fulcrum]

Do you have Vcc, Vdd, Vss, Vst, and Vcom connected? Also make sure signals like Reset and Vcom-Driver go somewhere appropriate. And check if any of the capacitors have shorted (those high density MLCC ones can fail shorted under thermal, mechanical, or electrical stress). There's also some outboard circuitry that's sometimes required like discharge, border switching, etc. There can be a lot to these displays, as I found out.

[tardy badger]

As far as I can tell, it’s all hooked up right. The recommended circuit is almost the same as the 1.54” EPD boards Adafruit sells aside from the RESE/GDR circuit bits

I’m probably messing up something simple though

[late fulcrum]

Yeah, mine's largely lifted from an eval board too. I think you're on the right track looking at the voltage, just need to figure out why it isn't there.

[chrome coral]

Is there any register documentation for the adafruit i2c rotary encoder? I want to access encoder rotation and set neopixel color and intensity

[static flare]

All the necessary code should be available in the learn guide

[sick adder]

What do y'all recommend as a versatile AVR microcontroller programmer these days? There's this based on USBtinyISP but I think that doesn't work well with many modern PCs due to the USB implementation. https://www.adafruit.com/product/46

@chrome coral https://learn.adafruit.com/adafruit-seesaw-atsamd09-breakout/neopixel for samd09 based seesaw and https://learn.adafruit.com/adafruit-attiny817-seesaw?view=all#neopixel for attiny based seesaw

the fw source for the samd09 based boards is https://github.com/adafruit/seesaw and for attiny based boards is https://github.com/adafruit/Adafruit_seesawPeripheral

[whole jacinth]

what protocols do you need it to speak? for SPI, i use an Arduino Micro flashed with an ArduinoISP sketch

[sick adder]

ah there's the overall seesaw register map!

@whole jacinth I'm not sure, I'm actually asking for a friend. As I understand it he wants a general AVR programmer though his specific "target" is an OpenEVSE

[whole jacinth]

(i have an AVR Dragon for if i need in-circuit debug, parallel programming, etc., but they’ve been discontinued)

[sick adder]

so it seems to be a atmega328p with the 6-pin programming header

[whole jacinth]

also for a retail tool, i’ve heard that the Atmel ICE is quite good (recommended by ladyada, even), but it’s more expensive, and might have more capabilities than needed (SWD, JTAG, etc)

[chrome coral]

they seem to sell a programmer on their site: https://store.openevse.com/collections/all-products/products/openevse-programmer

[whole jacinth]

anyway, most AVR Arduino boards with both USB and SPI interfaces can run ArduinoISP (even an Uno)

[whole jacinth]

that looks like a rebranded USBASP, which might still use a bit-banged USB interface?

[chrome coral]

looks like a USBASP v2

[whole jacinth]

i’m having trouble finding definitive info on the v2 hardware, but it still looks like a chip that lacks a USB PHY, so probably bit bang

[tardy badger]

[fierce prawn]

great

[ebon dew]

would require a piezo speaker to make noise, unnecessary fluff if you're trying to keep a microcontroller as slim & trim as possible. sounds like a neat addon for a custom board with custom UF2. idea in general is a neat one... unless you're deaf so for accessibility it's a bad idea. then again so is an LED indicator alone for someone who is blind.

ideally both a visual and audible indicator for accessibility would be more favorable.

i don't know of any blind people into microcontrollers though, at least not 100% blind.

[tardy badger]

Qi wireless charging 😄

[ebon dew]

how well does it work? hmmm 🧐 looks like a wire connected though.

[ebon dew]

oh derp that's the wireless charger board....an oxymoron.

[ebon dew]

is it really wireless if the charger board needs a wire? shower thoughts.

[tardy badger]

Well, wireless for the device being charged

[ebon dew]

yeah like even in tesla's wireless power transmission the infrastructure still has to be wired.

[wanton thistle]

ahh nice to see a follow up!

[ebon dew]

been following skerr's progress with great interest. i love seeing project updates from people's projects. wish more people would do it.

[tardy badger]

I’ve never made a wireless charger before this point and the fact that it’s working first prototype is exhilarating

[ebon dew]

same, when foamyguy actually got the TR-Cowbell to make sounds i could feel my heart rate increase. it's an amazing thing. makes you feel a bit like dr. frankenstein.

[wanton thistle]

I have to post my coffee roaster project at some point. But sickness got me down. Go Figure! and on vacation too

[ebon dew]

[wanton thistle]

its sitting here, mocking me, but my body is like "You need to chill".

[ebon dew]

lol a coffee maker with the express purpose of sugar and caffeine telling someone to chill out would make a funny comic.

[fierce prawn]

What about asking GitHub to brew coffee for you

[ebon dew]

a PIR sensor hooked up to a QT Py and MQTT feed to detect when you wake up in the morning sending a message to your coffee maker sounds like a neat project.

[fierce prawn]

Then a loud noise with American eas lol

[ebon dew]

stand alone voice recognition can't come to microcontrollers fast enough. so much we could do with that. i know it's out there and available but working it into circuit python would be awesome. i think the S3 Box has some functionality for it.

[fierce prawn]

Just load a tornado emergency alert from past event on a computer and have it send play control via a consumer control device to the computer

You will surely wake up

@ebon dew

[ebon dew]

the point isn't to wake up, plenty of things can do that. the point is to wake up to the smell of fresh coffee 🙂

[fierce prawn]

Aha

[tardy badger]

This thing is awesome 😎

[ebon dew]

would love to see you make a user page guide on it though i love reading about the progress

maybe a github gist with a build log

[tardy badger]

I’m going to compile a list one of these days

Probably a blog post on my site https://oakdev.tech

[ebon dew]

please do, the progress updates are inspiring to see how it started vs where it's at

your blog needs RSS

[tardy badger]

It has rss

[ebon dew]

i don't see an RSS icon at the bottom at least, needs one.

[tardy badger]

https://www.oakdev.tech/1/feed

It’s at the very bottom on mobile, sidebar on desktop

[ebon dew]

or perhaps in the top header. just a little orange RSS icon linked to the feed is helpful.

[ebon dew]

ah i missed it in the sidebar

got it, added

[tardy badger]

I’m honestly surprised the wireless charging worked right off. I’m also surprised I haven’t given up on this yet lol

[ebon dew]

that's really cool. with wireless editor like pyleap or something there would be no need to ever plug the watch into anything

[fierce prawn]

does it have data

[tardy badger]

What do you mean?

Like Wi-Fi/Bluetooth?

[fierce prawn]

data transfer over the charger

[tardy badger]

Oh, nah it just sends the Qi protocol

[fierce prawn]

hope it haves

lol

[ebon dew]

oh i guess there's the wifi workflow too though i've still never used it, doing everything via USB still.

[fierce prawn]

Holy I slept 6 hours

[brittle condor]

Ok so i wanna make a project similar to this one https://www.printables.com/model/337888-led-ring-lamp , except i want to use an addressable led strip and an esp32 to controll them with a capacitive touch button for input and a light sensor. I would like for it to work both as a lamp and as a clock + be able to integrate with my smart home to show notifications and stuff like that + use it as a wake up like (those that slowly brighten up in the morning)

My question is, anyone know some code already made that can do all this or do i have to make my own?

[late fulcrum]

You may need to roll your own, but not from scratch: there's probably code out there for the various pieces you want, you'd have to find it, put the pieces together, and make any adjustments required and customizations desired.

[brittle condor]

I did have to make custom code to control leds before so it wouldn't be anything new to me. I was just wondering if someone had my same problem and perhaps shared their code

I feel like that is a set of features that wouldn't be unreasonable to ask for

[wanton thistle]

Its worth searching github and see what you can find. Sometimes even bits of code are helpful, or if they documented it enough, comments.

maybe try ESP32 + lamp and see what comes up.

[brittle condor]

right, good idea, i always forget to do that

doesn't look like there is any that fits my idea :L

oh welp

i guess i'll do it my self

i'd have to modify it anyway cause i'm using sk6812 which are not very well supported even in fastled

does the esp3286 have some pins dedicated to capacitive touch sensors?

[brittle condor]

lmao the library i'm using doesn't even exist on github anymore

i guess i'll try to use fastled again but i had problems before with these particular leds

you could go the alt route: 4 PWM channels with RGBW LEDS. I know theres an SPI controller out there that will do it too.

It might be less a of a PITB to deal with changing duty cycles for each channel, that in, unless you specifically need individual LED s

Holy
That's what I got for today
Should be enough for tons of project

What should I do with them

[brittle condor]

found this "hack" that should work, i'll try it out https://www.partsnotincluded.com/fastled-rgbw-neopixels-sk6812/

[wanton thistle]

thermoelectric refrigerator.

But Im not sure, other than compost 🤷

[fierce prawn]

I have some planed for making a case that cover all the components inside for a keyboard
Good idea?

[wanton thistle]

oh! they make good knee pads at work tbh. They can support most people and are pretty strong.

[fierce prawn]

Does this looks good?
(Unassembled)

[wanton thistle]

ooh I get it now. You are using it as a case

[fierce prawn]

True

Good?

[wanton thistle]

Yea. it will work 🙂

Anyone have Makita tools? Would be a interesting DIY project. I have Ryobi and would love to DIY one

some of the stuff on Ali-express is just...really interesting too.

[late fulcrum]

I bought some dead cordless tools at a thrift shop and rebuilt their battery packs

[wanton thistle]

One of our customer sites has a bucket full of "dead" power tool packs. None I can use though.

[dusty citrus]

why though
there's plenty of cheap knockoffs

[wanton thistle]

Control. You get to decide which batteries go in. With knock offs, they could be using bottom of the barrel Lithium batteries. If you DIY it, you probably know where to get legit cells and so you have another aspect of control that goes into something

Ive been tempted to get the 3rd party batteries from Amazon for my mower, but, I could end up in a worse spot.

are there any other editors I can use that does similar job as the arduino ide ?

[whole jacinth]

what features don't you like about the Arduino IDE? what features do you want to keep? what editors do you already like to use? there's a VS Code extension for Arduino, for example

[oak abyss]

I use the official arduino IDE

[wanton thistle]

I think you can setup visual studio with arduino. Theres also eclipse.

[whole jacinth]

i think you can use any external editor you like, and use the Arduino IDE only for compiling and actual device programming (e.g., i used Emacs to edit Arduino sketches for a while)

[oak abyss]

aha

i do have visual studio code, wonder if this can be used ?

[whole jacinth]

yeah, there's an Arduino extension for Visual Studio Code. it works reasonably well, in my experience

[wanton thistle]

Ahh yea, notepad++ could be used too if you want simple

[oak abyss]

i guess i can check youtube for how to do that

this is quite funny, I am trying to play alittlebit around with ChatGPT and esp32, code seems to make sense, but probably some place in the system there is compatibility issues with the libraries, arduinojson for example. i uninstalled and reinstalled to get latest, but seems not to be.. otherwise chatgpt might not give correct code 🙂

anyone tried to make some code using this AI ?

[fair summit]

Don't trust ChatGPT as a source of knowledge. It could be right, or it could be completely wrong, and you can't tell. It's just cobbling together phrases from a large language model. It's like asking a parrot with a very large memory a question. Use a search engine.

I've had it write good code, and completely wrong code. It has invented the existence of libraries out of whole cloth.

[oak abyss]

aha yes I have noticed that sometimes it gives weird response, like when I asked it to create an ad for a fridge... like it came with noise cancelation and other practical perks like speakers, LED and lightsetup clockworks and an icemachine + flask for keeping a water 😄

still fun, and i think there is something to be learned from it anyway

[fair summit]

you could get hints from it, but finding a real working example that someone wrote is MUCH better. I will repeat, it's not a source of knowledge. It's a phrase assmebler. It doesn't attribute what it says to anything (no links). It could be completely wrong, but sound authoritative.

[whole jacinth]

yeah, lack of attribution could get you in big trouble on plagiarism or copyright stuff, if you publish stuff based on its output

[oak abyss]

ah

[oak abyss]

ok, another thing, do i always have to push the button on esp32 inorder to upload new sketch?

[thick wind]

Depends which board you’re using. If you have a board that requires the boot button pressed to load a sketch, yes you have to press it every time you reupload.

[oak abyss]

ah it seems just needed at the moment of upload, not needed to push all the time

[fierce prawn]

ESP32-C3 and ESP32-S3 boards currently provide an incomplete BLE implementation. Your program can act as a central, and connect to a peripheral. You can advertise, but you cannot create services. You cannot advertise anonymously. Pairing and bonding are not supported.

What

Board support it then
