That could be a soldier fly or a hover fly (they mimic bees so predators will think they sting) or an ant or a wasp. Wasp means Vespa, Vespula or Polistes or hornets, yellow jackets, and paper wasps respectively

[rapid geode]

its a bee

[late fulcrum]

Bees, ants, and wasps are all in the hymenoptera ("membrane winged") order, while flies are diptera ("two winged")

[rapid geode]

its a bee

[late fulcrum]

I wasn't arguing the point, just expanding on Adan's comment

🙂

they like my pumpkins. they dont touch the strawberries... shrug

[ebon dew]

i've always wanted to make one of those square molded watermelons. i wonder if you could do that for pumpkins to grow the profile of a face into them.

would make pumpkin carving a little easier 😛

[rapid geode]

ha

pumpkins are probably too strong. they will just break any mold / form

[whole jacinth]

nice! i was assuming that the 10% factory tolerance on the internal RC oscillator would be wide enough to cause problems for you, though maybe a one-time calibration would get you close enough if your voltage and temperature don't change a lot

[dusty citrus]

Hey, can someone please recommend some 200MHz logic analyzer up to 200$? Will this be 'good enough' but still way better than these 12$ 24MHz devices?

Oh, sorry for link. Will LA2016 USB Logic Analyzer Full 16 Channels 200MHz be ok?

[fair summit]

the link was fine, but the "bad words" checker has recently been expanded to include lots of wildcard matches, and something in the Amazon URL triggered. We are trying to get rid of these.

[dusty citrus]

oh, ok :)

This came in the post this week. 🙂 Started it at the end of 2019, helped throw the lock downs in the UK. I have CF so had to be extra safe. 🙂 52 this years so very pleased with myself. Not bad for a dyslexic that left school in 1985 illiterate.

[rapid geode]

well arent you a smarty pants 🙂

[hollow crystal]

I want to return a button that cost like $1.50 but had a $13 shipping cost, will Adafruit refund both costs?

[hollow crystal]

Congratssss

[dusty citrus]

@rapid geode did you mention that you make cncs?
can I dm you?

[rapid geode]

if you like. if its tech questions, might be better to post here so other people can answer too.

(or learn)

as the case may be

haha

[dusty citrus]

well you're right, gotta ask first here then decide what to do if either buy it from someone or trying to build one

I wanted to build(or buy) a cnc plasma cutter, but the problem is that I don't find any resources about the plasma head, besides basic stuff

I can find at best void heads which are pretty much useless? I have no idea of what to look for , I've tried different keywords but nothing relevant

[rapid geode]

you buy a plasma kit. for example everlast makes one that is cnc controllable. its a different torch shape vs the one youd use by hand. and it has some IO to allow the machine to control it

they are not cheap of course.

[dusty citrus]

I don't know? all I could find are stuff like this, which aren't supposed to be used manually?

[rapid geode]

https://www.everlastwelders.ca/powerplasma-82icnc.php

[dusty citrus]

but isn't it like a port?

[rapid geode]

it will have a connector for cnc IO

and a special torch

i dont know if the one you posted does the same. cant read it 😛

[arctic folio]

As a note Everlast is one of the bigger cheap brands for welders and such

Plasma cutters and tig torches being the same thing but with a different nozzle lel

[dusty citrus]

so it doesn't really matter, what changes in the end is the torch shape and io pins?

is it based on some side projects to convert such "manual" things to be automated friendly?
I mean isn't it a litte bit diyish/hobbist?

[arctic folio]

They'll also tend to have a higher duty cycle but all a plasma torch is a power supply with a gas nozzle

Idk what you mean by "is it based on" and diyish

[rapid geode]

these are the torches cnc machines use. cnc plasma is very 'hobby' as a whole.

production shops will use lasers as they are faster cleaner, more efficient etc

[arctic folio]

Eh there's a fair bit of industrial use

[rapid geode]

wrong wording, should have said DIY. i mean the machines (in the lower price ranges) tend to be this basic torch on a gantry format.

and not a more fancy integrated system like a router

[dusty citrus]

Hey, for 'average' every day hobby playing with hardware programming I will rather not use QSPI? It is used to communicate between microcontroller and external flash memory using SPI. Having it supported in logic analyzer is not that important, right? Similarly with MIPI-DSI LP? If I do not plan to do anything with smartphones'/laptops' displays, I will be ok without it?

Can somebody please take a look at this and tell me if it is ok? Thank you <3

[arctic folio]

it's not that the logic analyzer specifically supports those but that SQPI and DSI are far too fast

[dusty citrus]

Thank you for straightening it for me :)

Can I safely assume that I will not meet QSPI in popular cheap microcontrollers for tinkering? I checked few Adafruit products, and I got rp2040 QtPy, they use SPI, pico also uses it.

Ok, I think at this point it is used in industrial grade boards, and I will not get there for a long time :D

[fair summit]

qspi is used on our boards to talk to the external flash chips on these boards, not generally for anything else

the times I have had to monitor QSPI to check something, I mostly just needed to make sure the signals were working, not to decode it thoroughly

[dusty citrus]

Ok, great. So I can get cheaper LA, I guess :) Thank you.

[arctic folio]

if you've not had a logic analyzer prior I'd just get one of the 20$ units

the sort of tool that outgrowing is probably the way to go

[dusty citrus]

I read that pico can generate signals too fast to be properly detected by those cheap analyzers. I assume that it applies also to other boards based on rp2040. I am ok with spending some money, just not necessarily 300$ ;) The difference in price between LA from the screenshot and the one which can handle QSPI is 150$...

[arctic folio]

yeah an rp2040 can output a 100 mhz signal if you want it to

you can also use an rp2040 as a logic analyzer fwiw

there are like three projects which do it

[dusty citrus]

ha! I need to investigate this.

Thanks!

Found an interesting little website. Does not seem to be selling anything, it is just a nicely laid out site showing options for developing Linux desktop apps. They call for more Linux apps and not more Linux distros. Fair comment. makealinux.app

[molten pine]

so I got myself an ESP01

I read that it does support BLE

so I'm wondering if I could enable Fast Pair on it somehow? anyone know if that's possible?

[crystal ore]

I don't think the older ESP8266 chip in the ESP01 supports Bluetooth. The ESP32 chips generally have it, though.

[molten pine]

oh yeah, you're right. Thanks for your help!

The Desk of Ladyada - Bells of the Ball https://youtu.be/P-T4rlwboP4

[ebon dew]

I get what you’re saying and it would be cool for a custom board with no space constraints, unlike the feather or pico where Adafruit has to make tough choices. At best for the pico an adapter board could work but a breakout module is just that, modular.

[raven thunder]

@ebon dew Definitely agree it'd probably be a bit unnecessary for ESP32 boards, though what I was proposing what specifically for Pico ones, as their deep sleep power usage is.. not great, and as I said over in the other chat, I was thinking of it as an extra feature for some Cowbells, particularly as I think it's reasonable to assume that one with battery charging might be a thing.

[ebon dew]

There is a point where modularity becomes too much. Like if I wanted every feature from every featherwing, I’d have a feather tower.

If they made a featherwing that ensured my stack of featherwings became a low power stack that would be cool, but it would be yet another modular featherwing to add on the heap lol

[raven thunder]

Right, but again, I'm not suggesting a board just for this, and is it modularity becoming too much to have a little RTC on a battery board? I guess I truly don't know if an RTC for this is particularly big/expensive as a component? I think this is the one Pimoroni are using on almost all of their new PicoW boards: https://www.digikey.co.uk/en/products/detail/nxp-usa-inc/PCF85063AT-AY/5170038

Obviously the ABLIC one is probably pricier, gotta pay for all that dancing somehow 😉

[ebon dew]

The problem with rtc is the same as sd cards. It takes up a lot of real estate. If they were smaller I think you’d see them on more boards. Choices have to be made.

[raven thunder]

Obviously they do, but this seems much smaller than an SD card.

Or is it about the stuff you need to route to/from it?

[ebon dew]

I really liked the slim sd card holder she showed. Could put that in the middle of a board and have resistors and capacitors under it. Almost like a free little 3rd layer. Less real estate means more features. I’d love to see a board with like a 20W I2S amp but there’s just not enough room on a feather to the point everyone can have everything they might want. Gotta custom build it how you want.

[raven thunder]

I missed the start of it so didn't see that bit, though I'm still unsure as to how a 3mm chip takes up a lot of real estate on a board unless as above, it's about routing to/from it?

[ebon dew]

The 15mm card holder.

[raven thunder]

right, but isn't 15mm 5x 3mm?

[rapid geode]

O_o

[ebon dew]

Not if it’s 15x15?

[rapid geode]

have we gone from electronics to grade shool math?

😛

[ebon dew]

Oh we do it all here

[rapid geode]

hehe

make me an ethercat servo drive feather, and then a set of power stage feather wings

haha

[raven thunder]

The SD might be, yes, but I'm talking about the RTC

[raven thunder]

which you said would take up a lot of real estate

[ebon dew]

Pretty sure the rtc is bigger than the sd card holder

[rapid geode]

you need to get the traces out of it and routed to the other things

[raven thunder]

https://www.nxp.com/docs/en/data-sheet/PCF85063A.pdf I might just not be able to read datasheets when it comes to dimensions, but how is that bigger than a SD card holder?

[ebon dew]

Oh you mean the chip, I mean the battery holder, derp sorry

[raven thunder]

Ohhhhhhhh

When I said RTC, you were thinking a coin cell thing

[ebon dew]

Yes

[raven thunder]

Okay now this makes more sense

No, not a coin cell thing, just a teeny tiny RTC chip that works with the power supply the board has, and as I was imagining an Electric Cowbell that'd have a JST connector for a battery, it seemed like it could go on there.

[ebon dew]

If it doesn’t have a battery backup then WiFi or gps would be required to set it.

Yeah you can use huge external battery pack instead but that use adds to the project size if you want something smaller and self contained. Can’t make everyone happy.

[raven thunder]

As above though, I was imagining it as part of a board with a battery connector, and there might be different kinds of RTCs, I don't know if all of them actually need to know the actual canonical time to function in this way

[rapid geode]

fake time clock

[raven thunder]

Which is something that Adafruit support with pretty much every Feather, and sell a backpack for the QTPy to add as well, so I'm not sure it's a strange thing to expect they might make it too

[ebon dew]

They drift, all of them, and some pretty quick too. They need syncing occasionally.

[rapid geode]

i have the featherwing rtc

somewhere

with sd slot i think

https://www.adafruit.com/product/2922

that guy

[ebon dew]

I have the gps featherwing which also has an rtc. Works great thanks to neradoc fixing the library.

[raven thunder]

I mean, basically for this sort of use case, the point is more it doing something at regular intervals, it doesn't matter a lot if it happens at 3pm specifically, just that it powers the board, lets it do its thing, and either waits a certain amount of time, and/or waits for the board to say "I'm done!" and then cuts it again at regular intervals. I don't want this to seem like some kind of weird Pimoroni ad, but this is literally what they're doing for almost every single integrated Pico W product they're selling, so it doesn't seem like it's a super silly idea? https://shop.pimoroni.com/products/enviro-indoor?variant=40055644684371

[rapid geode]

well you dont need an rtc for that then

[ebon dew]

I love the rtc and sd card combo. I’d probably own one if my tft featherwing didn’t have an sd card.

[raven thunder]

What do you need instead? I was calling it an RTC because that's what they and NXP call it

[rapid geode]

if the board is powerd, it can "count" on its own. you only need RTC if that counting needs to be ultra precise (microseconds) or synchorised externally

[raven thunder]

Ah well the point here is to explicitly cut power to the board

[rapid geode]

then you need an rtc with a battery

[raven thunder]

So surely that'd work well on a Cowbell that has battery charging and therefore is going to be connected to a battery?

[rapid geode]

running it off a main short duration battery doesnt make lots of sense.

[raven thunder]

..did I just totally misunderstand the idea of Cowbells? I was assuming they're going to be like FeatherWings, but for the PicoW

[raven thunder]

What do you mean "main short duration battery"?

[ebon dew]

For power outages it does… for a zombie apocalypse not so much.

[rapid geode]

ha

well, normally you want the rtc uninteruptable over long times (months, years, decades). every time your main battery died (daily, weekly) it would reset the clock

[raven thunder]

Sure, but the aim here isn't datalogging, it's just power management, so why is that a big issue?

[rapid geode]

but then why do you need the rtc at all?

[raven thunder]

To get better low power performance

Unless I got what Cowbells are meant to be totally wrong. I was thinking Adafruit might make a Cowbell for the Pico/W that essentially does what this product does for the QT Py https://www.adafruit.com/product/5397. As the Pico/W is not very power efficient in terms of its deep sleep mode (it uses almost a whole 1mA), it might be good to have a little RTC chip on such a Cowbell that can control when its powered via intervals. That way you only have roughly 20uA of deep sleep current used (using the number Pimoroni cited), instead of closer to 1mA.

[rapid geode]

i guess

[raven thunder]

Can't seem to find power specs for the PicoW specifically yet, but the non wireless one uses 1.3mA in its sleep state with a clock which is the one I assume can be woken up. It'll obviously vary a lot depending on your overall project, but just playing around with a calculator for this stuff and going from 1.3mA of sleep current to 20uA, gets you around 37% more runtime.

Eh, this is apparently a pony that nobody other than Pimoroni and I like the idea of, and I've failed to even explain it to people in less than an hour, so never mind.

[rapid geode]

hahaha

i think i understand, but yes, i think it would be ultra niche

Hmm. i need a water pump that creates pressure. for my cnc spindle. the aquarium and pc ones do not push water through at any force.

[raven thunder]

I didn't think potentially a good chunk more battery life via an extra component on a battery board add-on would be ultra niche, but yeah, I get that it's just me (and Pimoroni) who seem to think otherwise.

[raven thunder]

I'd love to suggest something but my instinct is kinda to just go "water + electricity bad" 😉

[rapid geode]

ha

its niche because most people would want the coin cell

thats all

an independent supply

[late fulcrum]

Those are probably centrifugal pumps, you may need a positive displacement pump.

[rapid geode]

yeah

theres some cheap ones on amazon but they have bad reviews

[raven thunder]

Cheap/good/fast, pick two ;).

[crystal ore]

Or, if you live in 2022, you get to pick zero: everything is expensive, crappy, and out of stock. 😅

[rapid geode]

yup

haha

(And I'm mildly surprised that the hair-trigger bad-word filter let me say that, LOL)

Nah I'm in the UK and I've heard that expression

[raven thunder]

Hey, I managed to somehow snag a PPK2. In theory, if RS do actually get it to me this week..

Literally got what should have been the last one, waited to order because we had a record breaking heat last week here and I felt bad thinking I might be responsible for making warehouse/delivery folks run around in it for me

[rapid geode]

i wanted this, but its $350 shipping for a $462 item.

sigh

by the time shipping prices come down im sure it will be out of stock

[raven thunder]

darnit the bot nuked my pun too

[rapid geode]

haha

[raven thunder]

I'm not even sure how that's meant to be offensive, is "rage" okay?

[arctic folio]

I feel like that word filter causes more problems than it solves

[rapid geode]

it is doing substrings

[arctic folio]

good ol' scun*hrope problem

[rapid geode]

so, its rougue

ha yeah

[raven thunder]

does that make you feel rag ey (imagine the space isn't there)?

[raven thunder]

..can you raise both of your arms?

[blissful roost]

Just make a frame instead.

[timid anvil]

If anyone still plays castle crashers on xbox 360 i could use some help with a couple achievements

[kind stone]

the mild anxiety that comes from waiting for my magtag to come in the mail while knowing my dog likes to eat packages is consuming me

[dusty citrus]

have you considered to make it diy? or ask a local mechanic or see if there are any open workshop's around you?

bending metal tubing is annoying unless you do have special tools, but you could try with other designs/materials like fiber carbon , it's fairly easy, you can either use a mold or a polymer that I can't remember that dilutes in alcohol or anything that dissolves/can easily be removed

[rapid geode]

having someone make that frame would cost $3000. doing it myself is mostly impossible, partly for tube shaping, and partly for the heat treat process

i can do steel and titanium myself, but not 6061 aluminium

[late fulcrum]

Something like this might do. https://www.goldmine-elec-products.com/prodinfo.asp?number=G20479

[rapid geode]

Curious. Submersible might make it a no go (they often cant cool themselves). but I think that is the right idea.

rated for anti freeze. thats good. (amazon sells them too, but for way more money)

bad reviews, seems to died very fast.

bah

haha

there we go. "Duty Cycle: 20 minutes of continuous operation"

so, no go. need to run for hours and hours

[late fulcrum]

I wouldn't buy anything I needed to rely on from amazon.

[rapid geode]

well, not unless its a known item

not random no brand stuff

[late fulcrum]

That's just it: there are no "known items" on amazon, too much counterfeit crap and due to their "equivalent merchandise" policy of shipping an "equivalent" item from a closer warehouse for faster delivery, you could pay for a genuine item from a trusted seller, the seller could ship a genuine item, and you can still receive a fake.

[rapid geode]

oh, that is another topic. i only buy from amazon (not 3rd party sellers on amazon)

even then

:x

[static flare]

I mean, I've bought a couple of things from Amazon that I've been really happy with, mostly bench equipment

[late fulcrum]

Oh it's possible to get lucky, I'm not saying every single thing you could get from them will be bad. I will say that I loathe the company and do not do business with them.

[rapid geode]

That's another topic.

i forget why i signed up in the first place. wasnt til last year.

something i couldnt get elsewhere

[ebon dew]

@kind stone did you get the magtag from adafruit or digikey?

[static flare]

I do agree with you there, but alas it's somewhat unavoidable for me

[ebon dew]

adafruit was out of stock so i got mine from digikey and it comes wrapped in that paper packaging

adafruit said they'll be switching to it (no idea when) because it's cheaper and more environmentally friendly.

digikey has been using it for a while now. https://www.youtube.com/watch?v=QcCMXCadr2o

my magtag came wrapped up in a big ball of the stuff. unless it gets run over by a car the amount of cushiony filler it provides is excellent and far better than bubblewrap.

probably less dog proof than bubble wrap though so keep an eye out for your package

[rapid geode]

trying to rremember what my last digikey order came in...

think still plastic fedex packet

bubble wrapp

amazon is paper bubble wrap now

thats recent

[ebon dew]

maybe because i got something with a display

[late fulcrum]

I think DigiKey uses the Geami variant

[rapid geode]

oh, yes, it was in a carboard box. duh

reminded me

ha

[ebon dew]

well i mean it was in a box yes. i didn't receive just a big ball of paper wrapping. 😛

[timid anvil]

That guys dog eats packages?

[rapid geode]

the worst (wastefull) packing is from a bike store in the uk. they have an automated box maker but if you buy like, a bolt, it still comes in a giant box full of crumpled paper

[ebon dew]

apparently

[timid anvil]

Lol

[rapid geode]

oh you mean the individual packets with the boards inside?

mine were the usual ESD zip locs

[ebon dew]

that happens with amazon sometimes. i'll order something small and it comes a obscenely large box

though amazon is supposed to have an automatic box maker it doesn't always get it right.

[rapid geode]

thats how my cooktop smashed. they put the bocsh box inside a box 3x the size and no extra padding.

[ebon dew]

:*(

[timid anvil]

They have machines that put boxes together?

[ebon dew]

yes, cut to size

[rapid geode]

yeah, a lot of places have it now

[timid anvil]

Like it tapes them up?

[ebon dew]

amazon has the kind of money to have a system like that

[rapid geode]

but, they seem to have preset sizes, so its not always sensible

[timid anvil]

It folds an tapes them up?

[ebon dew]

yes

[rapid geode]

not sure about that, i think a human inspects at the end. but it scans the items, makes a box the "right" size"

[ebon dew]

there's a video of their system on youtube when it first debuted.

[timid anvil]

Im late to the party on this one yo

[rapid geode]

yeah, especially now, theres no amount of humans that could pick pack and ships all the stuff we buy online

[ebon dew]

i worked in a shipping dept for years, i guess stuff like that still jumps out and interests me. unsure if most people would even care.

[timid anvil]

Ive used a machine that seals plastic bags but a machine that puts boxes together dang

[rapid geode]

my friend does package design and i would 3d model boxes

which seems like a completely silly job

[ebon dew]

package design is fun!

[rapid geode]

but i had to "virtually" fold them correctly with the right die lines and print material

[ebon dew]

yeah that part no so fun

[timid anvil]

I've always wondered why places like Amazon send your stuff in huge wasteful sized boxes

[rapid geode]

there is going to be some math on package waste vs broken returned items

[ebon dew]

most of the time it's because they've run out of supplies waiting for a shipment of box materials, but can't stop working so you just choose the next biggest box available.. and then those run out... and eventually you're shipping small stuff in huge boxes. it's a logistics problem.

[rapid geode]

but then on my cooktop, it would have saved them money to pay a guy $50 (or $500) to hand pack it correctly

[ebon dew]

yes stuff like that is mind blowingly inexcusable, packed by people with half a brain cell and no f's given.

[rapid geode]

on the bright side, i have spare parts. haha

[timid anvil]

I've received like an SD card in a huge unprotected padded envelope

From Amazon

[ebon dew]

that would be funny to get a microsd card in a refrigerator sized box 😛

[rapid geode]

lowes was funny. i ordered basicalyl a whole bathroom, and it all came in separate ups shipments from all over the US and canada

[timid anvil]

Lol

[blissful roost]

I just picked up a large Amazon box....

... full of hay.

[rapid geode]

ha

with a single m3 screw?

[blissful roost]

No. Hay. 🤣

[rapid geode]

O_o

[timid anvil]

I've worked in shipping not for USPS or anyone like that but I'm pretty good at packing stuff up cuz I know how USPS treats their packages sometimes

[blissful roost]

Bunnies.

[rapid geode]

oooh

actual hay

[ebon dew]

yeah they're pulling stuff from different warehouses or 3rd parties. you can sacrifice shipping times by waiting for it to arrive in your warehouse, packing it in 1 box, or having them all separately shipped. 6 in one hand half dozen in the other.

[rapid geode]

dont you have like, a yard?

ha

[blissful roost]

Yarp. 😁

No yard in a 2-bed apartment

[ebon dew]

hay???

[blissful roost]

Yeah, it's the main food for bunnies

[timid anvil]

We deliver alot of hay is our slogan lol

[rapid geode]

my brother had bunnies, he said they were horrible pets

[ebon dew]

ohh it was on purpose, thought you meant as filler.

[blissful roost]

It would be great if I did have a yard though..
Space for them.. and I get unlimited fertilizer. 🤣

[rapid geode]

haha

we have wild bunnies here, but i rarely see them

something is eating my cucumbers though

either bunnies, squirrels or birds

[ebon dew]

time to make an automated defense system, pellet gun works better than a scarecrow.

[rapid geode]

hahaa

i know its illegal to kill squirrels and most birds

not sure on bunnies

rats you can kill

racoons no

but rats and racoons i dont think want cucumbers

they want trash

[ebon dew]

don't forget the trash cats

love those little guys

[rapid geode]

there was a cat in my yard saturday actually.

he can eat the rats

ha

[ebon dew]

https://tenor.com/view/rory-gif-24744734

[rapid geode]

that is, not a pet

what are those, possums? we dont have those here

[static flare]

I've always heard them called opossums

[rapid geode]

we have bunnies, squirrels, chipmunks, rats, mice, racoons, foxes, coyotes, deer, bears, moose, cougars. thats about it for wild animals.

ah ok

[static flare]

we also have possums, but there's no o, not even a dropped one

[rapid geode]

possums are pouchy type animals from aus I guess. i never knew that

the most evil animal we have here is the housecat

haha

[ebon dew]

oh you want evil... get a chihuahua with a bad temper. some of those things are little devils.

[fierce oyster]

hi

how i create a ap local host with a pico w?

they're very cute

[rapid geode]

here they all have little sweaters and socks and live in handbags

[dusty citrus]

[rapid geode]

machining steel carbon moulds and getting a heated press is not cheap and easy

[dusty citrus]

you don't really need a mold, wait a sec

[rapid geode]

yes, yes you very much do. you need 40-60psi and 325-350f for an hour or mor

[dusty citrus]

you can make a styrofoam core, then add sheets and epoxy, then once done, you can either remove the core with alcohol or let it inside

I've done one a while ago, and wasn't that difficult, smell aside

[rapid geode]

yeah the doesnt work for a bike really.

well, technically it works. in the same way you can make a bike from 2x4's. but it will not perform well

these are neat. printed ti lugs and filament wound tubing

but that at least for now, cost thousands (for the printing)

[quaint swan]

My PCBs are here

[static flare]

ooh fancy

[quaint swan]

good i already sew my big breadboards in half

[ebon dew]

that's a neat looking board

saves space on the breadboard

[kind stone]

Got it from just Adafruit, so I'll keep an eye out (and I guess report back on the packaging?).

[kind stone]

He's a very big dog who very much likes packages, yes

[blissful roost]

Got shipping confirmation for my Pi Pico W. 😁

[quaint swan]

I was so lucky my local shop had a bunch just when i was reading they are out now ^^

but be happy it took a bit 😄 there were some issues in micropython and arduino-pico with the WiFi

[blissful roost]

I might make a little unit for displaying sensor readings on a website.

[static flare]

I tried picking up even just one, but the local place I was going to buy them from mistakenly had them listed as in stock

it won't even let me check the lead time on Digikey

[blissful roost]

Oof

[rapid geode]

how muhc is it to make your own, i guess more than $6

[blissful roost]

Dunno

Probably

[dusty citrus]

I hate when I pass days on doing nothing like today

[rapid geode]

she's smiling cause she will be a pie this weekend

mmmm pie

[rapid geode]

haha

[blissful roost]

In other news...
Just purchased a BME280 module, to use with my Pico W.

[quaint swan]

Why can i only see the front and back layer paths on my pcbs when i shine through it with some light? Can't see any of the inside layers, are they kinda invisible? Like looking the same as the material around it? Sry for that question

[rapid geode]

did you make inside layers? haha.

[quaint swan]

yeh it all works as expected

[rapid geode]

🙂

[quaint swan]

thats why i wonder

I mean, kinda cool that you can't see them, one could "abuse" that 😄

[whole jacinth]

how are your ground and power planes? do you have much exposed board on either side?

[quaint swan]

i have no ground and power planes, because of space reasons ^^

[timid anvil]

I got blocked in a discord for saying Shout out to Minneapolis. Thats all i said. I wasnt in a conversation or nothing else just shout out to Minneapolis

[raven thunder]

Nice, though be aware the Sensirion sensors (or the TMP117) are generally more accurate for temp/humidity,

[blissful roost]

That's cool.
Shouldn't be too big a deal.. it doesn't need to be super-accurate.

[gusty torrent]

That's not really the right place, that topic is for broadcom pis, not rp2040.

[ebon dew]

yeah i don't have one, thought all pi's ran raspbian by default. 🤦‍♂️ probably should have recommended circuit python instead.

[dusty citrus]

with linuxcnc can I like place in the same heads multiple cutting tools, like a spindle, laser and torch?

[rapid geode]

theoreticallyu

but, those 3 machine types are best kept apart.

cnc needs precision and relative cleanliness. plasma use might damage it, it is filthy. and likewise laser. they also all need different base frame types.

people have done combo machines in the past, and they dont work out great

[winter trellis]

@night crescent is there going to be a john parks product pick today at 4pm? I don't see an announcement on the blog like usual

[night crescent]

@winter trellis will ping @swift hatch 🙂

jp has been summoned 🙂

[swift hatch]

@winter trellis yes there is. I post about that close to show time, which is why no blog post yet.

[dusty citrus]

maybe by swapping heads?

[rapid geode]

that would not be apart

like, literally you wouldnt want a router in the same room as a plasma

[shadow siren]

Something I should point out

https://www.adafruit.com/product/5441

Is this CAT5 or CAT5E because there is a difference, CAT5 is old and not produced anymore and is only 100M speed while CAT5E is current and is 1000M speed.

That item is not CAT5 it's CAT6A I zoomed in the pic, the cable looked familar since I have a server room with 300+ of these thin cables and they all were CAT6A

[ebon dew]

contact them on the website and leave feedback about an incorrectly labeled product

[raven thunder]

yeah, it says CAT6 on the datasheet: https://cdn-shop.adafruit.com/product-files/5441/5441_CAT6_UTP_1M.pdf

ewws at PVC cable

[shadow siren]

well due to a lot of places and fire code in the plenum the sleeve usually pvc material

I found in the product pages there was no link to submit a issue with the page unlike the guides pages so I posted to the forums

And the cable is CAT6A so it's actually rated at 10G

I love how the engineering drawing is incorrect when it's written on the cable

[raven thunder]

Weird, PVC is a toxic nightmare in fires

[whole jacinth]

i think US electrical code is to use teflon insulation in plenums, not PVC

[raven thunder]

Huh, teflon seems like expensive overkill when TPE/PE etc. could work?

[raven thunder]

I'd use the contact us form

[whole jacinth]

dunno, but it's what was needed last time i was wiring up buildings with Ethernet

[raven thunder]

I'm definitely looking forward to the EU banning PVC in a few years

[rapid geode]

PUR is what's in my cnc's for continuous flex. downside is the price. I wouldn't want to need hundreds of ft

[raven thunder]

Yeah, it's probably gonna be pricier than PVC, though I'd assume there's other options that aren't much pricier

[rapid geode]

not sure. i think i paid $100 for 3-4 metres.

(for 4 pair)

[raven thunder]

that sounds a lot pricier than i expected

though the cable options Digikey has are.. large

[rapid geode]

this is from misumi. dijikey didnt carry it, or didnt have it in stock, i forget

oh, i remember, digikey sells linde(sp?) which was 3x the price

:x

lapp

ah, yup. $5 a foot at digikey. so, not quite as bad as i remember. but still pretty bad.

[slim shard]

isn't teflon a slight environmental hazard?

[rapid geode]

if burned yes

but i think it depends how it is used, kinda like lead

on 3d printers, the pure teflon tubes will kill birds if burned

[vestal pier]

if Teflon gets too hot it decomposes and gives off hydrogen fluoride and Perfluoroisobutene gas, both of which are pretty nasty stuff

[rapid geode]

Isn't it great when you email a store about stock of an item on sale and they direct you to a completely different store where it isn't on sale?

sigh

[green swan]

The pcf8574 assembly video is so cool. And when I saw the itty bitty hot plate used I had to get one. It's so tiny.

[forest urchin]

Hello all, does anyone know if Peter Hinch who's active in micropython forums is present in this server too?

[slim shard]

I've not gotten the sense that anyone here is gung-ho about micropython here.

[forest urchin]

It's okay. I sorted my issue on my own. Turns out it was a mistake on my part. But yes, asking for micropython help in Circuitpython server was a stretch for sure 😅

[tardy badger]

There are people here that use MicroPython, just like we have people that use Arduino, or use embedded C, Rust, Etc.. and the circuitpython core team communicate with the MicroPython core team fairly often from my understanding. Since Circuitpython is a fork of MicroPython, generally speaking the knowledge is fairly cross-sectional 🙂

Usually we direct MicroPython questions to the #help-with-circuitpython or #help-with-projects channel, or if it’s something that can’t be figured out, the MicroPython forums/discussion boards

I know some might perceive a slight animosity towards MicroPython, but it really isn’t there. Many people have a good mutual respect of it because it is a valuable tool, and without MicroPython pioneering Python on hardware, we might not have ever had Circuitpython 🙂

I wanted to find the Circuitpython 7 poster because I think it epitomizes the deep connection between Circuitpython and MicroPython https://www.adafruit.com/product/5067

[slim shard]

I'm unlikely to have a good discussion of viper codes here :-)

[forest urchin]

My question was exactly about Viper and some wonderful code Peter had written in a git repo for micropython.

[forest urchin]

Thanks for explaining :)

[ebon dew]

Adafruit blog posted some scenes from wizard of oz that someone remastered in 4K, only short scenes not the entire movie. worth a look, it's mindblowing remastery of a film made in 1939 with RGB Technicolor.... https://youtu.be/PJZcQDSZzQc

[kind stone]

I think DHL has forgotten my magtag somewhere so now I'm just sitting here, waiting

[shadow siren]

check that you did your border duty fees in dhl

[nimble ice]

from yesterday but wanted to mention that I find a lot of online stores and vendors will use general images on listings like this instead of images for each variation so a inspection like that, while important, might not result in a accurate source of information.... like you might have seen the one you wanted but got another cable is the opposite side of this.... it sucks as I find reliability a big issue with a lot of sources

a lot of vendors tend to not even use their own sourced images of products as well so it can further complicate things

ironically one of the reasons I go with a lot of adafruit purchases is actually because of reliability tbh.

like I know on amazon, ebay, aliexpress etc that there is a high chance of getting something totally different from the images.

probably should send a email about the image and product description tbh. - edit: nvm, someone else must have as it is no longer stating cat5 in that link

[shadow siren]

I did that yesterday, I have 300+ of those cables and they are all CAT6a . They are getting popular in server rooms since you don't need them over 10' to run from switch to patch

[nimble ice]

yeah, I actually just last week started my first software dev job, I am 30 and have till now been a network engineer

so I totally know how annoying miss labeled cable listings can be

[shadow siren]

When I bought a sample of them I was skeptical that they were 6a rated and tried them out and lo and behold they did exactly what they were listed as being capable of.

Replaced these Shielded CAT6A

with these new thin ones

[nimble ice]

nice and clean XD a messy rack means a messy network afterall

[shadow siren]

this is what it was like before the change

[nimble ice]

oh yeah, I have had more issues with incorrectly listed coax over anything else though

you guys use a lot of fiber?

[shadow siren]

we have some for the ISP feeds but the inter connects between switches is those 10gig transceivers pre joined with thin twin-ax cable.

[tardy badger]

Dang, that’s a thick trunk of Ethernet

[shadow siren]

yeah it was very unmanagable

[tardy badger]

Should do fiber where you can

[nimble ice]

honestly coming into a messy network is really rough

ima look up what all is censored here because I said a word I know caused it but is used in casual speech XD I think I know why it was though

[tardy badger]

It’s from dynobot

It got updated with a ton of phrases wildcarded so it’s censoring normal words

[static flare]

It's a known issue, it's a bit overzealous

[shadow siren]

I could but you have to remember the connectors on fibre are fragile, I used this instead

[static flare]

I wonder if they fixed Saturday

good good

[nimble ice]

but honestly, without properly designing a network and documenting or labeling things that can easily eat up a bulk of a network improvement job for a network engineer works for a client or how a network admin gets their job done after the engineers leave.

yeah fiber woven is amazing and all but expensive and honestly not something you want unless there is a legitimate need for as maintaining that means you need qualified people for it

[shadow siren]

Somtimnes discord drives me nuts

I meant this pic

[nimble ice]

shouldn't even unplug fiber without plugging the port on the device and covering the plugs on the cable as dust alone can make things complicated

[shadow siren]

these use twin-ax coax to join the transceivers together

[tardy badger]

DAC are nice

[nimble ice]

ahhh, that makes sense, I replaced the word I used with "rough" but I used a word from a religion used to describe a place used to punish people.... "hxxlish"

so I understand why my comment got removed, but I did think it was a bit odd

[tardy badger]

I worked in a data center at one point so Ethernet was strictly for management. Network was done over 40G+ fiber

Though we did use 100G DAC for local interconnect

2m specialized DAC were like $50-$75 a piece. Wild

[nimble ice]

yeah, it also depends on the use.... like in places that are running a lot of data that needs to move fast between systems in the same rack you will sometimes use fiber but that means you then need to make sure only qualified people who know how to work with it do maintenance on them and also you have more costs etc

fiber isn't that annoying, but as it is a bit fragile it can be annoying to weave for sure

[tardy badger]

At the time I was just a Joe off the street

As we’re basically all the cable teams lol

[nimble ice]

honestly I feel like most people I knew that worked as network engineers or admins kind of "just walked into it one day"

[tardy badger]

Basically

Start as a temp with a technical temp agency and get an offer to stay full time.

[nimble ice]

like I was a IT support agent and got hired by a company for a network admin, they paid for and trained me into getting my CCNA etc and I leveled up overtime

[tardy badger]

Yeah, fairly normal

[nimble ice]

I wasn't even looking for that kind of work, just a higher paying job.

I was good with networking because I have always been doing my own stuff and college for CE etc

but I totally had never touched a cisco anything prior

during the interview the guy asked if I could name the position in the OSI model for a router and I didn't even know what the OSI model was

hired me anyway because I could describe the difference between a switch and a router without it

https://tenor.com/view/water-smile-drink-water-gif-13518129

[tardy badger]

Nice

Did you later figure out what OSI/TCP-IP layer a router was?

[nimble ice]

yeah, they paid for me to take CBT classes and get my certs etc

[tardy badger]

Oh right 😛

[arctic folio]

Twinax my beloved

When I started working in neteng at a <very very large multinational> I was a bit surprised to see off brand SFPs

Even for the links they used off brands
Same speed, just way higher failure rates

But you could buy like 16 for the price of one on brand and we did everything with 3 failovers

[rapid geode]

thought up a new product idea. just a button that makes a servo pull a cable. is there a chip/board that would basically be off until you press the button, and then wake up and actuate the servo within 100-200ms?

the ones i have seem to have at least a second or two 'boot up"

[kind stone]

Mhm, did! Paid it and then it said it's going to be delivered last Friday, then yesterday, no updates since Friday though, so :/

[late fulcrum]

You could probably make that out of a simple 555 timer, and have nearly instant response. On the other hand, if you use a solenoid instead of a servo to pull the cable, you could control it directly with a switch.

[rapid geode]

it needs to be tiny and have 20-50lbs of pull force, so i don't think a solenoid will do it. I do need an mcu though i think, because the cable pull amount varies.

[late fulcrum]

It's presumably possible to have an MCU boot in a few milliseconds. Probably fairly simple if it's in "sleep" mode, but not impossible from cold start with the right setup.

[rapid geode]

hm

[whole jacinth]

MCU boards that are designed to be beginner-friendly typically run a bootloader on power-up and might wait for a few seconds; you can likely remove this delay, but it's a somewhat advanced topic

[dusty citrus]

do all antenna work with every rf standard such as Bluetooth, uwb, wifi or whatever?
if not what I should look to understand what works and what not?

[rapid geode]

k, thanks. i guess first thing is just to make one with my feather m0 and a random servo to make sure the idea works

then go from there

uh, not m0. m4.

[late fulcrum]

Not really, although many standards can share antennas because they use similar frequency bands. Basically to choose an antenna, you need to match frequency band, power, connector, and impedance.

[dusty citrus]

also how does this stuff work?
https://www.amazon.com/Invisible-Secret-Wireless-Earphone-Earpiece/dp/B00CT5SQJQ

googling magnetic earphones or magnetic wireless headphones gives out nothing relevant...

[manic tide]

There's a giant magnet that you have to wear on your neck

[dusty citrus]

but the stuff that you put in your ear, why does it sound/vibrate?
does the effect have like a specific name?

[manic tide]

Due to some magnet induction (correct me) it makes this small magnet vibrate in magnetic field, just enough to move your ear drum

I've seen it on youtube some while ago when a guy was testing out ways to cheat on exam

Well, he described them sounding ok, but not too far

[lusty fossil]

Anyone ever experienced a 3 prong (US) plug that doesn't plug in all the way?

known good power strip

[ebon dew]

sounds like a manufacturing defect, i have some that are harder than they should be to plug in but they grip pretty tight too.

unplug it, take it apart, see if there's a defect. make sure there's no capacitors that could zap you before you start poking stuff. 😛

[shadow siren]

does the plug have the holes in the prong

[dusty citrus]

They've had them for telephones for many years; there's a jack for them.
'loop' is one term. They generally work with hearing aids.

Scientific American has an article induction-hearing-loop with the buzzwords I know about, in it. By Larry Greenemeier on October 19, 2009

The gist of the article is that it's an under-utilized tech base (a lot more could be done with the base technology in use for this system of hearing augmentation).

[tardy badger]

Adulting done right?

Fresh picked from my garden

Pickling cucumber and Japanese eggplant

[late fulcrum]

It was our first try for cucumbers, and we picked the first ones too late, oops

[tardy badger]

I found the cucumber by chance when watering. I hadn’t seen it the day before so I got lucky

I’ve got 5-6 pumpkins to pollinate tomorrow morning. Flowers are ready to open so it feels like an opportune moment

[burnt tendon]

My best-friend-besides-my-spouse likes to do things like garden so last year she planted some suspicious plant that might have been a Audrey II style mutant brassica sort of plant but ended up doing nothing. This year I let her do more and I've got about as many cherry tomatoes as I'd want.

I told her next year she can try planting a lemon cucumber because they are more ergonomic.

Like, once they were at Whole Foods and it's about the perfect size for a single salad! Totally ergonomic cucumber!

[rapid geode]

ha, i just did these with pickles and dill from the garden

pumpkins are fussy. 2 so far. most of the female blossoms fall off before they even open though

and 3 have opened, but failed to pollenate (even after doing it by hand)

[tardy badger]

Found little workers out doing their job this morning

I wasn’t sure if there were enough local bees to pollinate so I went out to hand pollinate the morning to find probably 20-30 bees busy working

Needless to say though, my pie pumpkin plants is taking over the grow box lol

Despite my efforts to terminate vines

[rapid geode]

i havent terminated anything yet cause im not getting enough pumpkins. i wanted 3-4 per vine (5 vines)

[tardy badger]

I have a solid 4 fruit flowering this morning, probably 2-3 more that will flower tomorrow

Plenty of fruit that just yellowed at 1-2cm in size and didn’t do anything

[rapid geode]

yeah, i have 1 that looks like it might open tomorrow, we'll see.

id like to get at least a dozen fruit to make pies

[tardy badger]

Yeah, that’s the purpose of my pumpkin growing. I love pumpkin pie lol..

[rapid geode]

my pumpkins are also growing vertical. im not sure if thats having any effect on the way they grow

[tardy badger]

No idea, I saw some ideas that I’m doing next year of using a wire arch to put the vines on

[rapid geode]

yeah i was gonna do an arch, but i didnt have the materials. so its just a frame. 12ft wide, 10ft high with mesh

[tardy badger]

Going to get a second plot to grow my pumpkin, watermelon, and squash on next year

It’s not a huge plot, like 4ft by 18ft?

I can probably add a few sqft by arching it up above the soil

[rapid geode]

one female waaaay up at the top. ready to open tomorrow or the next day

if it doesnt fall off

ill need a ladder to polinate it

[tardy badger]

Hehe..

[tardy badger]

Are these pie pumpkin?

[rapid geode]

yes

first one is almost ripe

[tardy badger]

Oh looks great!

Are you fertilizing at all?

We’ve mostly been throwing down MiracleGrow but I’m considering some bonemeal for calcium and whatnot to help fortify all the squash and gourds

[rapid geode]

i put promix in the soil about 1.5 months ago

havent done anything since

might need more soon

[tardy badger]

Gotcha, the plot we got looked like it was filled with leftover soil from construction so we added garden soil to as much of it as we could. Definitely doing more next year since we will have the time.

[rapid geode]

i dug out the soil, sifted it, and blended it with better soil. then some fertiliser.

my backyard is 12" of clay on rock. so, not much growsd without help

[tardy badger]

Yeah, it mostly looked like whatever sandy clay, alkaline soil exists in Utah is what we had

[rapid geode]

the front is a different story. i made stone beds and bought new soil

[tardy badger]

Looks great

[rapid geode]

yeah worked out nice. i have a peach and a plum tree to the left, and another bed with herbs and strawberries and back of the pic has 20 pepper plants

which are finally starting to bolt up.

my basil are trees, like 2ft tall

[tardy badger]

I noticed that most of my plants really struggled to take off at the beginning of the season

[rapid geode]

we had such odd weather this year

[tardy badger]

My watermelon have been in the ground for well over a month and are only just now getting bigger

I bought already propagated ones from Walmart too. The seeds I planted didn’t do anything

[rapid geode]

i need another pic now that its done

[tardy badger]

Oh looks really good

I wish I owned a home so I could do a lot more growing

I’m fortunate that I can rent a raised bed in my community for $10/m

[rapid geode]

ah thats nice

i dug all those rocks out of the ground. from leveling the ground to do my shed foundation.

[tardy badger]

Oh very cool

[rapid geode]

now i need to do the back yard. oof.

only 65x40ft but still a lot of would work to level out, build beds, etc

[tardy badger]

I’m a fan of growing fruit tree, shade, nectar source for bees, delicious results if done right

[rapid geode]

yeah

theres an apple tree too, but its living in a big pot until i make a proper place for it in the back.

need also another apple and plum tree for cross pollenating

[tardy badger]

I had a potted apple tree but a combination of the excessive heat, mountain fire blight, and a number of high wind events basically killed it :/

[rapid geode]

aw

[tardy badger]

Sad waste of $100 for a multiple variety tree.

[rapid geode]

yeah i had a meyer lemon but it died from 1 night in cold while i was moving

[tardy badger]

It probably would have been fine if it stayed on a patio like I had intended. But I moved and thought it would survive going from partial daytime sun to full sun. Nope..

I lived in an apartment before so I had a “balcony garden”

Which I’ve done successfully before with fruit trees, the change in daily environment was just too much I guess

[rapid geode]

i had a condo and it had no sun or bacony. so i tried to put all the plants at my machine shop. then they ripped that down for condos.

then covid

[tardy badger]

Dang

[rapid geode]

at which point i said, screw this, im buying a house

bought the cheapes house withing 300km (not even joking)

and have been slowing making it nice

but now interests rates are gone nuts, so i cant waste more money. just gotta pay it off

[tardy badger]

I’d almost rather have something that I can make my own through hard work than having something turn key.. but I grew up where most places I lived we had do do projects if some sort to make it better

[rapid geode]

actually, should say interest rates going back to normal. 0% was the nuts part

ha

[tardy badger]

True

5.54% interest rates here on good credit is making housing pretty expensive

[rapid geode]

i want to replace the house really, but its not viable right now.

[tardy badger]

And I already pay $2344 for a 3 bedroom townhome

[rapid geode]

yeah, its up to about 5-6% here now. (for fixed)

[tardy badger]

Homes in my area regularly sell for $500k+

[rapid geode]

see thats why i bought the cheapest house. i can pay the mortgage on EI. 690 every 2 weeks (about uh, $530us?)

downside, it's a very little house. but i dont mind that.

[tardy badger]

I only make $105k with lovely amounts of student loan debt because US education is expensive if you’re an adult learner supporting a family

So home ownership is more or less a pipe dream at current rates and home costs

[rapid geode]

this is the sad thing. i make a fair wage, and the cap the bank will give me was 500k. and there were like, 4 condemned houses in that price range, and maybe 3-4 slummy condos.

[tardy badger]

Geez

I applied for a home loan last year, best I could get was a $235k mortgage

[rapid geode]

almost bought one of the condemned houses actually. glad i got outbid, cause then this one came up. bad house still, but in a pretty nice area with good land.

[tardy badger]

No homes in my area for that except ones in HUD communities

[rapid geode]

and even though the house was bad, its so small that fixing it wasnt too expensive

it was 800-1m for a "nice" house here when i bought, and NOW more like 1.2-1.6m

[tardy badger]

So anyway, I’m not banking on federal loan forgiveness, but it would totally cut my student debt in half and wipe out my wife’s loans. It wouldn’t happen though.

[rapid geode]

nice as in, big, modern fixtures no repairs needed, just move in

[tardy badger]

I need to make like, a solid $25-30k more a years to tackle student debt at a rate fast enough to buy a house before my kids graduate high school

[rapid geode]

ew

[tardy badger]

Which I’ve got like… 11-12 more years before my oldest would graduate

[rapid geode]

oof

[tardy badger]

But federal loans when paid without income based payments take 10 years to pay off

15 year note on my private loans

[rapid geode]

im just trying to have my house paid off in 3-5 years. then my total monthly expenses (not counting food) are $700ish. then i can spend the rest on pies!

[tardy badger]

Hehe

I’m paying extra on my car to knock the note down faster

[rapid geode]

i dont have a car. cant be bothered with that

ha

[tardy badger]

$572 regular payment, I’m paying an extra $100/month to pay it down

[rapid geode]

ugh. i might get a motocycle soon, but that will be cash (6k i think it was)

[tardy badger]

Comes out to almost two extra payments every year which is cool

[rapid geode]

otherwise, i just ride my bicycle

needs more adafruit parts though 😛

[tardy badger]

I wish I could bike to work

But a 40 minute commute by car would be like, 2 hours by bike lol

I try my hardest to not have to go in and work remote

[rapid geode]

a 40 min car commute here is 6 mins by bike

:x

traffic is aweful

im 70km from the office now though

[tardy badger]

Yeah, I travel on a major highway and go nearly 30 miles

48km

Biking would be practical. And taking the commuter train in wouldn’t get me close to work

[rapid geode]

yeah. i just work at home. for now

[tardy badger]

I’m working from home right now, but I hear that they are pushing hard for people to go back to the office to justify the big $200m building they just finished building

Only reason for me to be in person is to go to the lab

[weary fiber]

welp, even though I'm underprepared, I forgot to reschedule my AWS exam

so I'm taking it 2pm today no matter what lmao

[tardy badger]

Whoops! Good luck!

I don’t know why DALL•E is so fascinating to use

[rapid geode]

um

this ai mostly makes super creepy things

[tardy badger]

Agreed

Oh wow, the one I did for “Pixar’s Outside In” was flagged by discord explicit 😆

It’s because it can’t draw great images

It basically mashed up Toy Story, Inside Out, and Monster’s Inc.

im guessign if theres enough pink colouring on a human form it thinks its naughty

[burnt tendon]

The worst part is when your friend sends you a photo of something cool they made and they held it in their hand and that's what set off the naughty filter.

[rapid geode]

ha

i did some dall-e things with cortana, and cause she is green they DONT flag as naughty

but maybe should

ha

i did 'cortana in a santa suit" and i very much got "office xmas party goes wrong"

[orchid zephyr]

i love those guys

[tardy badger]

I think Darkmode has been supported in the iOS app for a while though

Is it on the main website too now?

[orchid zephyr]

the components are my significant other

[orchid zephyr]

yeah

[tardy badger]

Lol

“I married my hobby” should be a valid option on tax forms

Because you’re providing 100% support and it’s dependent on you to live on

[orchid zephyr]

haha

[lusty fossil]

bigamy in your case right?

that's frowned upon *tut tut *

[tardy badger]

Yes, yes lol

[orchid zephyr]

hobbies are more of dependants than contributing members of the household though

[tardy badger]

My children don’t contribute, they only consume

Lol

[rapid geode]

children are just there to sell your stuff when you die

good thing I have sibings

they can take and sell crap when im dead

you draw with shapes and get code output to copy into your IDE with Adafruit gfx library

[tardy badger]

Very well done!

I got accepted into grad school again, this time somewhere cheaper lol

I guess they didn’t need a GRE after all

Hi! I'm not sure where else to put this message so I'm puting it here. I am a generative artist and I got a MacroPad I am going to use to make an interactive piece of art. I want to make the art in p5.js and the first piece was being able to press a button and have the p5.js program know that that happened. I probably could have gotten there faster if I had asked for help here, but I didn't (oops). But it took a while and was hard and yesterday I accomplished that! Wooo! Anyway now I am writing a blog post for my personal blog about how I did that and how I am version controlling my adafruit code. Can I submit a guide to the website?

[hard estuary]

kattni would know, but she's gone until Monday. I'm not sure who else might know

My magtag finally arrived (or, I finally was told to go pick it up) so heck yeah

[tardy badger]

I’m contemplating putting an ESP32-s2 or s3 mini module on this watch as a potential option. Seems like a fun idea

Do unconnected time keeping, Bluetooth time sync, or WiFi time sync.

[crystal ore]

There's also the ESP32-C3 as an option.

[tardy badger]

Oh true, I think that module is even smaller too

Could probably do an NRF module too

[wooden schooner]

Just climbed up and took a peek at the top of my bathroom medicine cabinet. How much danger am I in?

[ebon dew]

It’s one of those new ufl bulbs, so less danger? 😄

Shouldn’t that wire be in an electrical outlet? If it’s in a bathroom has to have a GFI too.

This is a case of temporary becoming permanent. I feel like that should get posted to Reddit. https://www.reddit.com/r/AnAttemptWasMade/

[wooden schooner]

I'm guessing the medicine cabinet is a hardwire thing. I agree that it should have a GFI...

not sure which wire you're referring to though

[ebon dew]

Ah probably ran directly into a vanity ballast originally.

Like a shop light that ran across the length of the top.

[wooden schooner]

I replaced the pictured bulbs with LED bulbs. I didn't see any ballasts.

Yes, the cabinet looks like it should have a tube light going across the top, but it has these Edison sockets instead...

so you're guessing the ballast was mounted to the wall and was at some point removed, leaving that hole?

[ebon dew]

They don’t last forever, probably burned out long ago and someone hardwired a light bulb fixture. Unless you’re saying you’re the one that wired it?

[wooden schooner]

nooooope

I am trying to decide whether to push my landlord hard to fix it

[ebon dew]

Ok yeah they last eh 5-10 years. Then start flickering and poof one day. The flickering isn’t the bulb but the ballast when the ballast is dying… weak output too.

Definitely not to code to have exposed wiring… sitting on top of a metal cabinet.

[wooden schooner]

I know it's not to code... neither is the rest of my apartment

but like, this particular code violation seems more dangerous than something like not having enough counter space on each side of the stove top...

[ebon dew]

Hire an electrician and give them your landlords billing address.

[wooden schooner]

I assume that is sarcasm

[ebon dew]

Not really. Cheaper then a wrongful death lawsuit if it kills one of your friends visiting.

[wooden schooner]

afaik, the landlord gets to choose which electrician he hires. All I can do is threaten to bring him to tenant court if he doesn't hire someone.

[ebon dew]

If you tell your landlord about it then by law he’s got to have that one fixed.

Medicine cabinet is above the sink i assume?

[wooden schooner]

yeah. same is true for any code violation, afaik. but I'm trying to pick my battles here, and this looks like one that is worth picking

yes, it's above the sink.

[ebon dew]

and how long is the wire? See where I’m going with this?

[wooden schooner]

that it could fall down?

[ebon dew]

Yes and he moved you with it in that condition, he probably broke a law right there.

[wooden schooner]

he definitely broke and is breaking laws. I am not trying to figure out whether he is breaking laws, he definitely is. I'm trying to figure out what to do as a tenant

thanks for helping me work this out btw

I think I'll send him that photo, explain the danger, and see what he says/does

[ebon dew]

Most states have some kind of renters rights website you can consult about your rights in your state.

Which should be a state website or .gov website.

[wooden schooner]

yeah. If I need to straight-up threaten him, that's the place to go. For now, the question is whether it's worth pushing him to fix this, given that he could try to get rid of me if he considers me a troublemaker or whatever.

the scales seem very in favor of at least bringing it up and seeing what he says. "Hi, just wanted to let you know about this obviously dangerous thing, wdyt"

[ebon dew]

If he considers you a trouble maker??? When he’s already put your life in danger. Nah, your life is worth pushing back on this one.

[wooden schooner]

thanks for the reality check on that one. I used to live in San Francisco, where many apartments are very dangerous and the landlords are often quite clueless. At the time at least, tenants often didn't exercise their rights because getting on their landlord's bad side would be very expensive (eviction and sky-high rents).

[cosmic oasis]

Mmmm wire caps. Jk, but on a serious note, I’m trying to find out if wire caps are considered an unfit long term solution regarding residential electrical code.

But that dust along with it tho

[wooden schooner]

yeah, plenty of dust. does that add significantly to the risk?

also, uh: this is the cabinet https://www.wilmar.com/Sku/53-5022/zenith-2438-in-x-195-in-lighted-sliding-door-surface-mount-medicine-cabinet-in-chrome-043197007018-701l

looks like @ebon dew's guess was quite possibly right... looks like when the ballast died, someone took off the top of the cabinet and replaced the strip light with bulb sockets. wth

I have no idea who made the "Specification" PDF on that page, but fwiw it does say "ELECTRICAL REQUIREMENTS: Unit should be wired to circuit w/ Ground Fault Interrupt Protection"... which in my apartment it is not

oh wait, it also says "LIGHTS: 2 Incandescent 75 watt max each with Plastic Diffuser UL E-80195 Issue No A-201,604"

so the cabinet does come with those weird bulb sockets, it just also requires a GFI elsewhere in the circuit

[cosmic oasis]

Your lights are all kinds of if I was confident in fixing it, I’d offer to fix it for reduced rent for a month or something. Just sayin if the offer presents itself, they don’t absolutely have to accept, but then they’d have to “get someone I know who can do it cheaper,” which we all know what that leads to

[ebon dew]

would you want to clean the top of that thing with all those loose wires? lol you'd have to flip the breaker first just to make sure you could clean the dust.

so it's just the light diffuser that's smashed up exposing it all? still the wire connections and wire nuts should be in an electrical box in the wall at least.

is this close? http://www.apcabinets.com/pdf_files/701L.pdf

the only replacement parts they offer are glass/plastic shelfs and hinges. you'll have to make a replacement diffuser out of diffused plexiglass.

yeah it's a Zenith Vanity Model 701L

Still available from AceHardware, HomeDepot, Lowes, and Walmart

[reef bobcat]

FYI - For those who find tio useful you may also find lxi-tools useful. It is another open source project of mine to manage modern network attached test instruments: https://github.com/lxi-tools/lxi-tools

It includes both a gui and command-line application.

[wooden schooner]

yep, that's the one

[wooden schooner]

the person has to be a licensed electrician or else the landlord is still liable

[wooden schooner]

yeah, buying a new vanity is probably the cheapest solution

thanks all for your help

[cosmic oasis]

Landlord will go find the lowest bidder unfortunately, speaking as a former property manager. I hate property management so much. Not for having to fix stuff, but for wanting to fix stuff and being told “no, it’s too expensive. We promised the owner we’d make them money this month, and if we don’t, they’ll find someone else to manage the property.” It’s a sick game of chicken and everyone is running around with their heads cut off. It’s insane, but that’s a discussion regarding the dollar and real estate that will QUICKLY get political if nobody stops me

Technology is fun. Younger generations use it to describe new and interesting things.

Though one interesting thing I’ve noticed is it’s mostly older generations I get stuck behind at stop lights playing on their phones :/

I’m kind of a mid millennial, not quite the end but not quite the start

It’s kind of a weird thing to experience honestly

[burnt tendon]

I feel like I am fundamentally too uncool to actually be part of an organized generation.

Also, by generation timings, I'm between anyway.

[rapid geode]

[hasty quarry]

Well, I don't use Twitter but I know the type of language you're talking about

[vestal rain]

Without a use yet. They'll get used at some point. Also, I bought two, not two hundred. The reason there aren't any is because there aren't any. It's a new board, more will be available when more are made.

[rapid geode]

im still blaming you. its easier

ill also blame you for the crazy shipping prices from the UK

https://tenor.com/view/tom-holland-spiderman-peter-parker-infinity-war-your-fault-gif-12347008

[burnt tendon]

Totally logical.

You should be ashamed of yourself.

[ebon dew]

i usually buy in 2's especially if i think i'll make a lora node out of them someday.

[blissful roost]

I only got 1 myself.. but then, I already have 2 regular Pico.

[ebon dew]

i don't have any, i can wait until things calm down and the scalpers realize they've made a huge mistake sitting on thousands or tens of thousands of boards.

i mean if anything it's making the esp32-s2 and s3 look much more appealing.. hmm maybe espressif is behind it. 😛

[vestal rain]

I pretty much always buy in pairs. One usually gets header pins for breadboard prototyping, one gets used for whatever I'm testing.

[blissful roost]

CONSPIRACY!

And can you tell when typing which keys are which switch?

[lusty fossil]

[orchid zephyr]

Only 2 blues though

[weary fiber]

Home row + space browns: osu!mania

Two upper browns: osu!standard

Two upper blues: osu!standard also

[orchid zephyr]

I could never type like that, osu players are always ridiculously dedicated lol

[weary fiber]

The typing experience is noticeable at first, but it goes away fast

I didn’t buy a mechanical kb for typing, I bought it for rhythm games anyway lmao

[orchid zephyr]

Oh lol

I use mine for both

[weary fiber]

But yeah, I’m pretty proud of its lifespan, I’ve maintained the thing meticulously & it’s been my only keyboard for all those 7 years

[cosmic oasis]

7 years. Dang, dedicated

[rapid geode]

keyboards disposable. you replace them when the cat hair prevents the keys from moving

[ebon dew]

yeah because i have a cheap keyboard i don't care about eating or drinking near it. let the chips fall where they may and i'll clean it up someday.

if i had an expensive kb don't think i'd be as comfortable having a drink anywhere in arms reach.

[weary fiber]

Done cleaning!

[static flare]

I didn't see the blues!

I have a Drop Alt with all blues

[weary fiber]

I wish I could go with a different keyboard brand, but corsair’s combo of wrist-rest + media keys + volume knob is so good

Like it gives me the ability to just feel for pause/play when listening to music in-game

And the volume knob is 👌

Well, it’s cheap as knobs go, but having one at all is so convenient

[ebon dew]

very nice. that's pretty much what i want to build. a full sized keyboard with media keys and a calculator button. calculator button is a requirement.

maybe some potentiometers for volume macros. i don't really use the media keys often because they're digital buttons but if i had a potentiometer i think i'd be more likely to actually use that.

maybe a keyboard with a small built in mixing console, now that would be nice.

and a bluetooth amplfier...

and a cup holder for my cup

and that's all i need

[blissful roost]

Yeah, just cut away chunks of it until you get to the part you want to use.

[dusty citrus]

is it already gone, or can I like dremel inside without destroying it?

[weary fiber]

why not just buy a new usb B cable?

you can probably get one at an office supply store for a few bucks

they're used as usb cables for printers, so they're easy to find at Office Max or somethin

[hasty quarry]

Quick question, since I don’t quite understand something

Does a capacitor impede more and more as it charges?

And then does it basically just completely impede when it can’t hold any more?

Because if the voltage across it rises, and current doesn’t change, surely its resistance is going up, right?

[late fulcrum]

Generally there's an impedance of the source charging it, so as the voltage rises, the current drops.

[hasty quarry]

Oh, I see

I’m sort of having an identity crisis because I’m struggling to get job opportunities doing what I actually want to do which is work closer to hardware. I don’t mind software engineering, but I’m really not loving it career wise

[dusty citrus]

I see, I can understand you

[tardy badger]

I had an embedded role that I liked but I got laid off so back to software engineering I went

So I’m going to ram my brain through a Masters in Electrical Engineering in like.. 18 months

My determination to not be a software engineer for the rest of my career drives me forward

[ebon dew]

The nice thing about programming for hardware is it's set in stone, no shifting design goals once a PCB is made. That's also the bad thing about it too.

both good and bad ideas can change the world. all theory is useless until given a pragmatic application.

[dusty citrus]

i was just wondering, instead of hooking up a electret microphone directly to a esp32 for my my projects that includes Sound input and performing all the processing myself, Would it be possible to use any kind of Sound card (like the one shown below) with an esp32, Like by converting it's output to TTL logic by using FTDI or something?
let me know your opinions on this

[grim dome]

OpenScad, and there is something else I was reading about last night

[burnt tendon]

Oof, yeah, I am where I am today because I studied really hard in college to try and be either a game programmer or a special effects software engineer... but it turns out that the workplace happiness for there is so bad that I'm arguably happier not doing games or special effects, just being a software engineer, LOL.

(For all of the usual hassles with being a software engineer, of course)

[vestal rain]

Not sure if anyone here can help me but I'm hoping so. I need to convert this file:

https://github.com/MReavley/Slice36/blob/main/Plate/Slice36 Plate.dxf

to a .svg so I can have it laser cut. I don't know how I can actually get this .dxf file in the correct format to be converted. What's available just seems to be a bunch of text and if I try to open it in Autocad it doesn't load.

[rapid geode]

acad must open it.. however, it may be 3d dxf

[late fulcrum]

QCAD might be worth a try

[vestal rain]

I think the first problem is I'm not sure how to download it as the .dxf it's supposed to be. It opens online as a bunch of text. Do I just have to git clone it?

[late fulcrum]

Worth a try

[shadow siren]

acad files like dxf are text in nature, they are like Postscript which is also text, the text tells the cad program how to draw all the lines, since cad is a vector based system.

[rapid geode]

i think hes implying only text comes in, which suggest 1 or both of 2 things. 3d or incompatible polylines

[shadow siren]

if you use qcad I believe in order to view dxf files you need bought version

[vestal rain]

git clone worked. Thanks for your help though.

[still anchor]

But doublecheck the scale is correct

[vestal rain]

Thanks. I got it into an svg but my scale was WAY off.

[tardy badger]

My pumpkins are really getting big

Growing like crazy day to day

Still smöl but getting probably 1-2cm larger in diameter each day

[late fulcrum]

Many of the laser cutting services ask you to add the desired dimensions to the drawing so they can scale it as needed. It's a good sanity check in any case.

[dusty citrus]

this is a very ot question, but I do have like a really bad surname, which means like hand, foot or another body part
I was thinking to change it, but I have literally no idea on what to change it... any suggestions?

[crystal ore]

I'd say that sort of question is kind of similar to getting a tattoo. You'd want something aesthetically attractive and personally meaningful, though maybe the meaning is obscure enough to not be immediately obvious to everyone.

However, I will mention that you definitely want a name that people can spell correctly when hearing it! If I had a nickel for every time I had to say, "No, that's k-e-y-EEE-s"... 😅

[vestal rain]

I have to spell out my last name every time I give it to someone verbally. It's an uncommon spelling of a common name.

[dusty citrus]

I'm pretty used to it, they Always spelled both my name and surname wrongly

maybe Ly? it works out like a nickname, short, and it's pretty much generic,

[hasty quarry]

What is a "Henry" for inductors, I haven't really looked into this before

My dad asked if I could figure out how to use an old solenoid he found, but giving it some small DC seems to really, really upset my power supply

And I measured the solenoid to be about 1 Henry and 40 ohms, but I do not know what's going on or if that means much

[tardy badger]

According to Google: kg m 2 s -2 A -2

[crystal ore]

Well, it's a unit of inductance: produces 1 V with a current change of 1 amp/sec. Inductors on PCBs are typically like micro-henries, but a big solenoid would be much larger.

[tardy badger]

1 kg meter squared per second squared per ampere squared

[hasty quarry]

So 1 Henry seems reasonable for this thing?

[crystal ore]

Seems large to me, but my intuition isn't great there, and I have no idea how big it is.

[tardy badger]

Yeah, size would tell you if it was reasonable

Large solenoids, definitely

[tardy badger]

Smaller ones like Adafruit sells, those would probably be a few tens if milliHenry if not a few hundred milliHenry

[hasty quarry]

Oh, now just wait a second

I think I just misread something

Yikes yes, I misread my reader, it's actually about 1 mH 🤦‍♂️

Though I am not sure how to get this thing actually working. Passing some 5V DC makes my supply really unhappy

Let me try mains DC

[crystal ore]

Well, bear in mind that it's just a long wire, so you're essentially just shorting your power supply with extra steps. 😉

[hasty quarry]

But it is 40 ohms though

Although...yeah that's actually a lot of draw, isn't it

Probably

[crystal ore]

Hmmm, should be only 120mA or so at 5V, so wouldn't expect a problem there necessarily.

[hasty quarry]

Oh, right

Yeah, I'm really not sure, then

As you can also read in the svg file I used the open source inkscape. It takes a while to get to know the GUI, but if you just want to convert stuff, you just open the file and save it in a different format.
