Have you checked out haiku?

It's surprisingly usable!

Yeah.. couldn't find a reason to actually use it though.

I can't progress past that, because 32bit.

You've got me thinking, maybe one of those IN-13 neon bargraph displays as a CPU meter...

raw jasper
#

Have you programmed the real thing?

late fulcrum
#

I only had a tiny amount of time on a real PDP-11/70, I spent most of my time on the department's VAX-11/780

#

I did log a lot of hours on a PDP-11/23 and a PDP-11/05 previously, however

late fulcrum
#

The PDP-11/23 was running AT&T v7 Unix, the VAX was running BSD, and the 11/05 was running a bizarre system by LeCroy Research called ORACL

Fair.

I'm not into the whole tube lamp thing.. doesn't appeal to me.

This is a completely silly question, but is there a PDF reader that supports regex search?

The last time I did something like that, I used Python and PDFPlumber, which is likely overkill (in one axis) and not a PDF reader (in another axis)

I wonder if it's possible to let IO expander control the SPI CS lines.

thick wind
#

Not for hardware spi, but software spi might be possible.

crystal ore
#

Even hardware SPI should work okay. You'd just flip the CS line in software at the start of the transaction, then kick off the hardware SPI to control the clock and data, then when it's done manually control CS again. There's usually not any timing constraint between CS and the other signals.

I think esp32 is lenient on however we do at CS

MCP23017 has an issue where pin 7 can only be used as an output not an input or something like that. Well you can but depending on what batch you got the chip in it might cause random issues. The issue is well known and goes back a decade. If it's your first time working with the MCP23017 it's something to be made aware of.

raw jasper
#

Something probably went wrong during the multi-corner timing analysis for that part...

ebon dew
#

The problem goes back a decade. They only just this year actually documented it in the datasheet.

raw jasper
#

Yeah, I'm just trying to make an educated guess on how that kind of error happened

#

Don't mind me, just trying to apply the vlsi stuff I'm trying to pick up on the side

#

:)

ebon dew
#

management... it's quite obvious they would have known about it and swept it under the rug for increased profilts.

raw jasper
#

I guess rushed product development would be one part

ebon dew
#

Don't get me wrong they're amazing chips, I love them and will use them anyway but now at least I know to avoid using that pin as an input.

raw jasper
#

But I'm surprised they haven't revised the design since

ebon dew
#

maybe someday, would be nice. there are alternatives and that's kind of the problem. by admitting the issue they'd lose to their closest competitor for a real 8 input 8 output multiplexer.

Yup. The 2007 data sheet didn't mention the issue, but the 2021 data sheet did, or something like that. I'm kind of tempted to see if it can work with interrupts (either by polling the interrupt status bits or using the interrupt directly)

Anyways, I've been "lucky" for a couple years. No colds/flu - but my wife got the flu and I did not. I was also hospitalized 2 years ago (surgery), and tested like 8 times for covid, always negative. I guess I was due. The wife got the cold first then sure enough I did...🙁

I've been wanting to do a SAMD11 board so I made a little shim

late fulcrum
#

It looks like there may be just enough room to make it narrower, so it takes up one less row when plugged into a breadboard.

tardy badger
#

perhaps, there's still a bit of space available for sure

#

and at $4 from oshpark, not terrible price wise.

late fulcrum
#

Sweet. Other than the USB connector, it looks hand solderable, but of course it would be easier with solder paste and hot air/hot plate/oven

#

Why the bounce in the traces here?

tardy badger
#

No reason really

#

Other than just trying to keep the distance between traces somewhat consistent

#

Other than that no real reason

#

The distance is so short and the speed is so slow it makes no difference lol

late fulcrum
#

I probably care more about the æsthetics of routing than I need to.

tardy badger
#

Good looking boards are always nice to achieve, I can’t argue with the aesthetics bit

raw jasper
#

I'm curious, is LVS (layout vs schematic) a thing done in PCB design too?

tardy badger
#

In a way

#

You typically do your schematic and then do the board layout against that schematic

raw jasper
#

Does the tool check they agree?

tardy badger
#

Yes

#

As well as determining if your board design follows DRC

raw jasper
#

Interesting!

raw jasper
#

There's an observation to be made in jest here that IC design is just PCB design with more layers

late fulcrum
#

Similar kinds of spatial reasoning and problem solving, but with some fun extra dimensions.

raw jasper
#

Have you ever done IC layout? Just curious

Yes, arduino uno

tardy badger

Hmm okay, and you’re hooking up the SPI pins in the right order and toggling the SD CS pin?

I don't know exactly what that means, but I have the SD CS pin hooked up to Digital 4 and I am using the pinout provided on the learn guide.

Do you have a picture of your setup (maybe we should move this to #help-with-arduino as well)

The push-button telephone is a telephone that has buttons or keys for dialing a telephone number, in contrast to having a rotary dial as in earlier telephone instruments.

#

I wouldn't consider myself highly experienced in handling electronics, but I kind of wonder if it'd be stupid to make my own bridge rectifier and inputting my wall to it. Is that probably a bad idea?

raw jasper
#

I'd recommend against playing with mains voltage if you don't have the relevant experience

#

Power supplies are cheap, and always a better option than potentially risking death

hasty quarry
#

I could really die doing that? I really don't know how likely that is

raw jasper
#

I mean, mains power is no joke

hasty quarry
#

What would kill me? Getting cooked from completing the circuit? A fire?

raw jasper
#

Probably completing a circuit with the mains

patent hemlock
#

cardiac arrest is the usual outcome

hasty quarry
#

I did it on accident once and my vision went black instantly. Luckily I let go quickly. So yeah, it's scary, I agree

raw jasper
#

You were lucky

#

Usually the electrical current interferes with normal muscle control, locking your muscles and not allowing you to let go

hasty quarry
#

Oh, I've heard of that

#

A friend of mine wants nothing to do with electricity because his dad saved him from that when he was young and he says the way his hands did their own thing was horrific

raw jasper
#

Yeah muscle contraction is electricity-based

acoustic pawn
#

watch electroboom's video on making a FBR

hasty quarry
#

Let's say I take precautions necessary to not complete a circuit, what could go the worst from attempting to rectify mains myself?

hasty quarry
raw jasper
#

(Before anyone corrects me, I know that is not entirely true. What's fair to say is that a big contributor to muscle contraction signalling is electricity, and there's an ionic component to the muscle contraction cycle itself)

acoustic pawn
#

those are some of the more stupid risks, but they are risks nonetheless

fair summit
acoustic pawn
#

a fuse and inrush current limiter would make it a little safer

patent hemlock
#

and note that the fire would start at a weak point, so it wouldn't even be near to where you're messing with things

hasty quarry
#

What tends to be a weak point in a house

acoustic pawn
#

but you're always better off with a power supply

hasty quarry
#

The transformer?

acoustic pawn
#

unless you need 170V DC

raw jasper
#

The wiring itself

#

If the fuse fails

acoustic pawn
#

maybe contacts

raw jasper
#

Yeah, contacts too

acoustic pawn
#

contact resistance can cause heating and 🔥

raw jasper
#

Anyway, all fuses, except for the GFCI, are to protect the house from catching on fire, not you

acoustic pawn
#

probably if you want to do stuff with mains, be on a gfci protected circuit

raw jasper
#

Just don't do it at all w/o the proper training

hasty quarry
#

I guess I won't go through with it

#

Although I'm curious, are there certifications for this or something that could provide me with the knowledge to do this safely?

solar kindle
acoustic pawn
#

same. Any certification or safety things for working with mains

raw jasper
#

Well, I guess going to trade school to become an electrician would be a start

fair summit
raw jasper
#

Oh no. I need to be more careful around unknown old radios

hasty quarry
#

Sorry, you sure that's meant to reply to me?

fair summit
#

also called "AC-DC"

acoustic pawn
#

Maybe getting some measurement and other equipment like a variac, GFCI, fuses, current monitor, some sort of configurable overcurrent shutoff might be good for safety

raw jasper
#

Just forget about it :)

hasty quarry
#

I guess I'll consult an electrician if I really want to do this sort of thing. That should work out best, right

fair summit
#

not an electrician, a EE

#

experienced in power supply design

hasty quarry
#

All the way, an EE?

#

Oh, right

raw jasper
#

You'll probably never need to do that, unless you're developing a product commercially that has special power needs

#

So many power supply modules to choose from!

acoustic pawn
#

most SMPS designs are very similar

#

FBR, bulk caps, step down flyback, feedback, output

#

of course there's more stuff

#

but that's the basic design

hasty quarry
#

I've been really curious about the way transformers work. Mostly because I learned about Maxwell's laws and magnetic flux and whatnot recently

#

But why's there a sort of stigma around transformers?

raw jasper
#

I mean, SPICE is a thing

#

You can simulate what you need to learn there

hasty quarry
#

That they'll kill you instantly

raw jasper
#

Well, if the voltage / current combination is sufficient, they can definitely do that

hasty quarry
#

Microwaves. That's the context I was told that in

raw jasper
#

A "microwave transformer" (ie. a transformer used in microwave ovens) definitely fulfills the criteria to be deadly

https://www.youtube.com/watch?v=FBeSKL9zVro

There's a reason I never make videos featuring MOTs (Microwave Oven Transformers). The high voltage, and more importantly - high current, means they are as dangerous as playing with overhead lines.

This does NOT apply to the spot welder projects where the dangerous high voltage secondary is removed completely and replaced with a few turns of h...

patent hemlock
#

there's a stigma around transformers connected to mains - that's a lot of (pun intended) potential for a lot of energy

thick wind
#

Transformers for microwaves usually have a high-voltage secondary winding that generates something in the range of 2-3kV, iirc

hasty quarry
#

I'll definitely watch that video, but in microwaves, do the transformers intend to turn the flux into a higher voltage signal, or lower?

thick wind
#

Not something to be playing with without some research.

patent hemlock
#

microwaves cook food - you are no different from food

hasty quarry
#

Is this just something that's usually done to make super powerful frequencies?

#

X-ray machines and such too?

#

Wait, I misplaced them, those aren't as powerful (x-rays I mean)

#

Well thanks for the video ningen, that's pretty much what I was looking for

raw jasper
#

Definitely try SPICE to simulate and learn, though!

hasty quarry
#

Curious, is your name "humans" in Japanese on purpose

raw jasper
#

Human being, singular

#

And, yeah

hasty quarry
#

Ah, alright

#

no plurals gets me again

raw jasper
#

I mean, you can form collective nouns with 〜たち or 〜ら, but it's usually not needed

hasty quarry
#

Right

raw jasper
hasty quarry
#

I haven't really gotten used to when it's more or less proper to use those though

#

Oh cool

raw jasper
hasty quarry
#

I have seen those yeah

raw jasper
#

You won't hear something like アヒルたちは泳げる

#

That'd just be アヒルは泳げる. You can typically also drop the は

hasty quarry
#

But it's things like 彼ら being preferred over 彼たち. I haven't determined a difference

raw jasper
#

I think it's an euphonics thing

hasty quarry
#

Yeah it doesn't look too concrete, it should come with more input

raw jasper
#

You'll really rarely see 彼 in Japanese though, it's typically 〇〇さん

#

(Or whichever honorific makes sense)

hasty quarry
#

Well, isn't that "he" though? You're saying that's not common?

raw jasper
#

(Unless you want to say "boyfriend")

hasty quarry
#

Yeah I know it's in that word, but I thought it meant "he"

raw jasper
hasty quarry
#

I see

#

But what if you don't know their name? その人?

raw jasper
#

You'd typically say something like 山田さん〇〇〇〇〇〇〇〇 in the first sentence, and just skip the topic in the following ones

#

(Because Japanese tends to drop any information that can be inferred from context)

hasty quarry
#

Yeah I really need to get more comfortable with what stuff my English/Spanish brain makes me feel is important when it's not

raw jasper
#

Just be mindful that 彼 means both "that guy" and "boyfriend" (as in, that guy)

#

(same with 彼女)

hasty quarry
#

What was "man" again? Radicals 田 and 力 I believe

raw jasper
#

彼 does not contain the "man" component

#

It does include the "person" component, though

#

(rightmost one, 人 -> イ)

hasty quarry
#

Oh I remembered, 男, おとこ

#

Is that rude

raw jasper
#

That (along with the more scientific/medical-sounding 男性) refers to the male condition

hasty quarry
#

So...don't try that one, you're saying

#

Hah

raw jasper
#

I mean, you could say あの男 ("that man"), but at that point, we're splitting hair

hasty quarry
#

Are you a native speaker or did you learn

#

I've been teaching myself for a while

raw jasper
#

I'm still learning

#

So many things to do, so little time

hasty quarry
#

Yes

#

I find it kinda funny how 男 and things of the sort have such historic and cultural ties to the way they lived their lives

#

It's just so cool that within the language itself there is so much meaning and culture

#

The components of 男 just say "rice field laborer" in a sense, it's really interesting how the history is in there

raw jasper
hasty quarry
#

Oh, hey, look at that

#

I definitely don't agree, obviously, but there's something really neat about there being a story, some story, to all of these little things

raw jasper
#

Being an outside observer, I am not going to make any statements regarding the writing system of a culture that is not mine

#

It is up to the people who use it to have this discussion if they need to

#

What I can make is the academic observation that, with some characters, you're getting 3000-year-old stereotypes

#

(Which I definitely don't agree with either!)

hasty quarry
#

To clarify, it's those stereotypes you can find that I don't agree with, not you

raw jasper
#

dw, I correctly understood you

hasty quarry
#

I've been thinking of, but too scared to, experiment with consuming media with no help

#

As in like, watching TV or reading despite not understanding most of it

raw jasper
#

Something that might help is getting a popup dictionary extension

hasty quarry
#

And the argument I've seen for it is that your brain is incredible at piecing together things like that

raw jasper
#

That way, as long as you know the grammar, you can read random text you find on the web

hasty quarry
#

It's the "difference between being explained to you why a joke is funny, and actually finding it funny because you get it"

raw jasper
hasty quarry
#

What in the world

#

That looks pretty cool

raw jasper
#

Enjoy!

cunning frost
#

I've done that before, just watching anime raw, and it's a good learning experience because it forces you to think beyond what books can give you. A lot of the Japanese language kinda wings it and it's very easy to get too attached to what you learn in books.

#

All of that flies off the window once you realize how fluid the language can be to express just about anything.

raw jasper
#

Funny thing about me is that, even though I am learning Japanese, I do not particularly like anime or manga. As such, I can't really offer any advice regarding that

cunning frost
#

That's fair since my learning advice is to just follow your interest in the language. You'll learn it one way or the other.

raw jasper
#

Yeah, that sounds about right

ebon dew

hear all the time that people from other countries learned English by watching American movies. it goes both ways.

when you hang out with people who only speak a foreign language your brain picks it up much faster

Being a non-native speaker of English: English is literally everywhere, even on the packaging of things you buy. It definitely Helps[TM]

ebon dew
#

i learned some German a long time ago hanging out in German IRC channels.

raw jasper

...At least, it builds the kind of pathways that are sufficient to go "aha! I've seen this word" once one formally learns it

ebon dew
#

subtitles help but like all learning... repetition is the key

raw jasper
#

much of it is practice too

ebon dew
#

practice is repetition

raw jasper
#

There's an argument to be made on the distinction between active (ie. practice) vs. passive (ie. revision) repetition.

#

And some philosophical conundrums over how much language speaking is conscious thought vs stochastic parroting, but that's another story

ebon dew
#

memetic responses are natural and begins in childhood. it's instinctual and part of the learning process.

I have this class project, I want to make the same function as an airtag. I was wondering if this is possible through adafruit components?

late fulcrum
#

To do all the functions of an AirTag, you'd need Bluetooth, GPS, and NFC. AdaFruit does sell boards that do those things, but the end product would be somewhat bulkier than an AirTag

old beacon
late fulcrum
#

There are lots of Bluetooth options, perhaps one of the Feathers like product IDs 2829 or 3406 might do, which will give you both Bluetooth and a CPU, as well as a battery charger. Perhaps the Ultimate GPS FeatherWing (product ID 3133), which will stack right on top would be a useful addition. I'm not aware of a STEMMA or Feather format NFC breakout, product ID 364 would probably work, just need to wire it in. You may want some details like Feather stacking headers, maybe an amplified GPS antenna, and/or a rechargeable cell (product ID 3898 is just the right size to fit on top of or under a Feather). Or you may prefer not to go with the Feather format, all these things are available in other forms as well.

I’m not sure the modules Adafruit sells has nfc broken out, so that might be an issue

I’ve run a feather bluefruit express with gps featherwing and external gps antenna. Works great. Most i did was sync time from my phone. Dont know if you can plug into nfc capabilities with it. Might be worth looking into the nrf52840 library?

#

Also the gps module is only a receiver. It cannot transmit its location, you’d need some other method to report back the location data it receives.

#

Such as a cellular modem or lora…

The AirTags have neither, they apparently just make a Bluetooth link with passing iDevices and hand off their data that way.

pivoting from the chat in #help-with-circuitpython, I do like the idea of a self contained "digital coffee cup" but that's probably a little outside of my expertise level for actually manufacturing

#

might be fun to hack together a prototype though

ebon dew
#

to put the temp sensor in the actual liquid might require a special cup

radiant coral
#

I like your idea of hacking apart a double walled cup to install the heater and not have it be actually immersed though @fickle ridge

ebon dew
#

you can stick the sensor to the bottom but would that be good enough? i dunno.

#

especially if you wanted the built in heater on the bottom instead.

#

might actually need a triple walled cup

radiant coral
#

I don't know that the temperature variance in a regular coffee cup would be significant, but in a taller mug I guess I'd want the sensor near the top since that's what actually would be hitting my lips

ebon dew

ah that's a better idea

#

but as you drink the level changes

#

would need to be on a float?

ah yes, physics is a pain sometimes

float switch also means you could monitor your coffee level remaining even with a lid on 😉

there would definitely be additional weight. by the time you add the heater, float, temp sensor, display. yes. still would probably be worth it. the ultimate coffee cup.

fickle ridge
#

you obviously can stuff multiple sensors into the hollow wall and glue them in to measure coffee temperature at various heights to determine mean. maybe even add a magnetic stirr bar to uniform it.
the heatsink to bottom of cup needs a ring to seal the vaccum and the peltier in.
i guess below the heatsink a printed plastic? enclosure for microcontroller and the wireless coils to receive power from a power pad

#

routing the wires thru the vaccum seals looks nasty.

do some of them have hollow plastic bottoms? sounds ideal for hacking, that's awesome.

i thought they were double walled all the way around in 1 process

i doubt it, i'm pretty sure they're all stainless to keep the vaccum

you could design heater element on bottom

with RISC-V soldering iron have heater element what heat faster to desired temp

i wouldn't immerse the sensor into liquid, i would glue it inside the hollow walls

#

~1mm of stainless changes temperature quick enough to give a good reading on the liquid

ebon dew

does look like there might be enough space for a really compact build in the bottom. would have to be a custom pcb and could withstand the heat from desoldering itself apart.

having all on bottom could be great when its sealed

or you could add a brushless motor with an encased propeller, some gyros and accelerometers, record typical drinking motions, and run a neural net to predict further drinking motions, and then have the motor and propeller generate lift to assist in drinking to counteract some of the weight. needs a small lithium battery, something with super high discharge current capabilities and maybe some DC DC buck converter to increase voltage ?

I wonder, at the scale this is happening in the USA, do "gun nuts" get enough lead exposure for it to be medically significant?

ebon dew
#

that's where tagging comes in.

#

untagged vs tagged traffic

golden saffron
ebon dew
#

switch will only route tagged packets to vlans with those tags. subnetting can get complicated.

#

you would normally configure tagging in your switch, not the router or firewall.

dusty citrus
#

Alright but for example when I get a plug and play usb device to work, the usb has an id that comunicates a code to the os, which will then proceed to install the correct drivers

But if I connect like a phone and a printer, how does the switch not misslead the comunication? If a single port can be both tagged and untagged and support multiple vlans?

ebon dew
#

wlans can also be setup with zones so things get pretty complicated if you're working with wlans. no two networks are really configured the same so you have to know routing pretty well. vlan tagging is 802.11q protocol.

#

i don't think comparing vlans to usb cdc is a good way to associate it.

#

i think of tagging more like traffic lights

#

would recommend looking up some youtube videos on switch tagging, videos will do a much better job of explaining it than i can with text.

dusty citrus
#

I got it, the id is a pointless name, they could allow extra ruling though

ebon dew
#

also don't trust tagging as a security measure, use firewall rules in conjunction with vlans.

elfin bridge
#

Tagging is just that. The packet gets tagged with the VLAN number. The port will only pass tagged traffic that matches a VLAN it is configured to allow. Each port has a default VLAN. If a packet shows up without a tag, it gets handled as if it were tagged for that default VLAN.

#

Each VLAN gets treated as if it were a physically separate Local Area Network. Acts the same as if you had separate switches, but each port can pretend it's on multiple different switches. The only way it knows witch virtual switch the packet is intended for is with the tagging.

burnt tendon
#

Yah, the big thing there is that, without VLAN tagging, you'd end up wanting to run a looooot more ethernet.

elfin bridge
#

If you have a switchport configured to allow VLANs 8, 13, and 52, and set it to default to 8, then it's like that port is a part of three different switches, one for 8, one for 13, and one for 52.

burnt tendon
#

It's a feature that's in the electronics of the switch, understanding that when I say "electronics of the switch" I really mean "at a lower place in the tower of individually programmable often much more specialized CPU cores that create the hallucination of the modern computer"

elfin bridge
#

A packet comes in tagged with 52, the virtual switch for VLAN 52 handles it. A packet comes in with no tag, the virtual switch for VLAN 8 handles it.

burnt tendon
#

That being said, yeah, sure, if you set up a VLAN and don't have a firewall to actually segment the network, it's window-dressing

ebon dew
#

yup, instead of a rack of switches with 200 ports and physically connecting everything like an old phone switchboard vlans allow a single ethernet cable to split traffic. a switch with vlan capability helps keep the size of the network rack down to a minimum. less gear, more capability.

elfin bridge
#

So back to the phone and printer question, it is very likely that the phone is configured to tag its packets for the phone VLAN, and the printer is sending untagged packets that get handled by the native VLAN.

ebon dew
#

i honestly think chaining vlan aware switches downstream is fun to setup. it really helps to have a home lab setup where you can tryout different configurations without worrying about taking down an entire segment of a corporate network by accident (which will eventually happen no matter how careful you are) 😛

Ohh Digi-Key is rebranding

ebon dew
#

why

#

they have great brand recognition..

tardy badger
#

New logo, colors. No name change

ebon dew
#

ohh ok

#

I don't understand the glitching effect... generally glitch isn't something you want associated with electronic components.

#

though they do sell the MCP23017

patent hemlock
#

it's showing the font change - each letter change is a basic electronic component

ebon dew
#

will a non-electronic person realize that? no.

keep in mind this stuff is done by pr people, who don't necessarily "talk" to engineers (or at least not very well)

I don't like the new logo :(

the video puts everything into a better context. yes good job.

The rebrand removes the hyphen in digi-key also.

which I think is a good move, just my opinion

Speaking of logos that look like components...

Looked it up. It's a bank.

Yes. However, it looks like a “capacitor bank” to me

Ah yes, time to store my money in the big capacitor

I don’t know if it uses Anadigm chips though

Ohhh they have a Field Programmable Mixed-Signal Array

Maybe the license the architecture?

What kind of circuits?

Like ones you’d turn into a physical product?

#

Or are you more interested in simulation?

Uh idk, this is where i'm at. Imagine sprinkling in some port extenders
I have some prototype boards, might end up ordering some custom PCBs, idk yet.

It’s a cortex M0+

Yeah, it's a cool little chip, but definitely not a Zynq competitor, digital-wise

I wonder how much it costs

tardy badger

$2.42 for a single

Plus supporting circuitry

Probably an NDA for the full datasheet

In any case, it is not what I was looking for anyway

There are programmable mixed signal devices like renesas’s greenpak ICs?

On Digikey and Mouser last time I checked, but the variant I want isn't in stock so I didn't pick them up

I did see the eval boards

I was looking for bare chips

olive dome
#

Yeah like I said, the chip comes with that socket adaptor

SLG46537V-SKT

#

You kind of need them to do prototype so I guess it makes sense for them to bundle with the programming adaptor

tardy badger
#

Yeah, true

olive dome

Though it is programming with I2C

Nah, I was just posting the stuff that is in-stock without actually looking at the spec

SLG46826 looks nice, in stock at Mouser

But there are certainly more cursed footprints

tardy badger

There are definitely more cursed footprints, I was just filing it there with them lol

raw jasper
#

I gotta give it to them, Renesas seem to be very creative with their application notes

#

Washing machine, blinds controller

tardy badger

They make cheap chips for everyday applications, so it makes sense

I imagine you’d find their chips in a very broad set of appliances

I found CAD files for standard picos, but i noticed i apparently bought some clone with a bit of a different layout. Does this design have a name to google with?
It's a 16MB flash, USB-C equipped raspberry pi pico clone i guess.

tardy badger
#

Not sure, you might check the listing your purchased it from

raw jasper
#

If I had the disposable money and spare time, I'd definitely get a greenpak devboard

#

It even has an integrated signal generator

fickle ridge
#

The listing wasn't very helpful, i ended up drawing even the pinout myself by copy pasting off other pinouts and some trial and error

raw jasper
#

Though the simple devboard without them goes for "only" $39

fickle ridge
#

It's just listed as RP2040 TYPE-C Lite Black - 16MB

raw jasper
#

That's one of the problems with the cheap clones, you pay in time

fickle ridge
#

Well i had no clue what to look out for when i bought it and it was like 3 bucks so

raw jasper
#

Well, enjoy the challenge!

fickle ridge
#

what challenge?

raw jasper
#

Of adapting your design to the clone

fickle ridge
#

there is no design so 🤷

raw jasper
#

Ah, I assumed you had something you needed to work with, since you were looking for CAD files

fickle ridge
#

i want to build an I/O shield to plug this into to connect to various other boards

raw jasper
#

👍

fickle ridge
#

I dont really have a use for any of the standard shields that are offered so i have to do my own thing anyways 🤷

thick wind
#

It’s still a standard header, I’d be surprised if the standard pico footprint didn’t work.

i compared the pins, they're not in the same places.

This is the cheapest Avant FPGA coming from Lattice Semi

my QT Py S2 is reading 95°F right now, in a 70°F room ...it's never really going to show you ambient temp

raw jasper
#

raw jasper
ebon dew
#

on board temp sensors are good for measuring the temperature of the board, nothing more.

#

which isn't an issue for most situations but if it's say sitting inside a gear closet, in the middle of Florida summer at 120F you can have it automatically shut down if it gets too hot. that's honestly the best use case for an on-board temp sensor.

#

now you might say 120F ha there's no way... yes way. monitoring that closet temp was part of my old job. imagine walking into a hotel sauna that has racks of gear in it. that was my daily working environment. it's cheaper to let gear fry from heat and replace it once a year than to pay for AC to cool the room. it was literally part of their business model.

it used to get to 140°F in my attic until I had it properly ventilated when replacing the roof, now it only gets to 120°F max. But I do have quite a bit of electronics in there (that will soon be moving to a new part of the attic that should always be close to room temperature).

Gents, sure this has been asked B4... Why are Raspberry PI's never available anywhere? Do they even make them, or very slowly in small lots? I have no idea.

You can go with CPU's that have on-board graphics. You won't play a lot of high end games with them but it'll work for most personal PC uses.

#

It's funny that the price of GPU's started skyrocketing shortly after motherboard manufacturers stopped putting on-board graphics into most motherboards. An external GPU became mandatory instead of optional for most motherboards.

raw jasper
#

On-board graphics are a part of the CPU, not the mobo

patent hemlock
#

iirc, not originally

ebon dew
#

lol

#

Yes, that is actually a very recent change. On board graphics used to always be ON the motherboard.

Amazon sells double the $$ of Ada

raw jasper
ebon dew
#

hence the term "on-board". today it's technically "on-cpu"

patent hemlock
#

MB manfuacturers stopped doing it because everyone was buying external cards, so it became (basically) a loss-factor

patent hemlock
ebon dew
#

not for most business, productivity workstations. those used to have no need for an external GPU

#

the default configuration for all motherboard ended up gravitating towards "gamer" builds... and we live here now.

patent hemlock
#

"business workstations" caused a bit of a flashback to PS/2 from IBM and those razor sharp hole covers

raw jasper
#

In a PC build, I typically dump most of my budget on the CPU. Traditionally, this left no leftover cash to get a GPU with, and since gaming is not really a thing I do, I've only ever had a computer with an external GPU exactly once

#

cases have come a long way too, they used to be razer sharp. the avg case today is like 10x nicer than the avg case from 20 years ago.
