general-chat

[late fulcrum]

Is that price or cost to make?

[tardy badger]

Cost to make is ~$5

[late fulcrum]

Not bad.

[tardy badger]

No including my time to assemble

PixelWing boards cost ~$17 to make, selling for $39.95

PixelLeaf RP2040 cost ~$11 to make, selling for $29.95

most expensive portion of the PixelLeaf RP2040 are the neopixel which I buy on a reel

[late fulcrum]

The Boarduinos in the picture were built from the bare PCBs that AdaFruit used to sell: a product that doesn't even show up on the website any more, even as "discontinued". https://www.adafruit.com/product/69

[tardy badger]

Wow

A piece of ada history

Kind of cool 🙂

Sometimes I wish I had the tenacity and drive Ladyada has

[delicate stream]

Hax

[tardy badger]

She is so darn inspiring

[delicate stream]

I wish I had 1/10th her drive and passion

[late fulcrum]

Fervently agreed. I've learned so much from her.

[delicate stream]

And like 1/100th her engineering skill, lol

[tardy badger]

I got better at part sourcing because of Desk of Ladyada

And better about trying to be unique with designs because of New Products section of Ask an Engineer

[late fulcrum]

I got better at PCB layout (both technically and in a zen sense) from her tutorials

[tardy badger]

Yeah

I’ve learned a ton from the community and being able to give back has helped a lot

[delicate stream]

Navigating the part madness is the easy part for me XD I've had LOADS of practice using the same sort of search systems for PC hardware, so as long as I know the general specs of the part, I can probably find an equivalent... It's knowing all the how to mix parts and actually design circuits I need work with, lol

[tardy badger]

True

So so true

I had to learn not to be so stringent on what I used in my designs

[late fulcrum]

Wading through the bewildering variety of LEDs on offer to choose just the right ones for a costume prop was an adventure

[tardy badger]

Yeah

[delicate stream]

throws NeoPixels at everything

[late fulcrum]

I even bought the fancy optical epoxy to glue them in place from DigiKey, a princely 4 grams of it.

[tardy badger]

Finding a supplier of sk6812 was a scary journey for me because I had never ordered off Aliexpress before

[late fulcrum]

I found some 199 LEDs per meter LED strip overseas, but $50 for shipping dissuaded me from actually buying any.

[delicate stream]

Personally I recycle as much old knowledge as possible into everything I do -- why research a whole new solution if you can tweak an existing one? Thus NeoPixels going into most of what I do, lol

[or NeoPixel compatibles]

[late fulcrum]

I did the same trick to use an Arduino port to program a project instead of learning a whole 'nother code development environment (I did ultimately end up building a custom board definition and memory map)

[delicate stream]

lol

[tardy badger]

Lol

I was kind of terrified at making my first circuitpython board

[delicate stream]

I have no fear, I know exactly what I want to do, and it's a simple design, so I'mma go full steam at it! soon™️

[tardy badger]

I started with the 328p which you know is so over done that anyone can make an Arduino board with it lol

So going to something that I had to figure out making my own board definition and bootloader. It was new and I wasn’t sure at all how to accomplish that

Thankfully Adafruit has the resources to make that easy too

And then making a circuitpython definition and adding it to circuitpython.org

[delicate stream]

I made a 328p board by hand, lol

[tardy badger]

Or requesting a PID 😱

And also learning that joining the USB standards org is expensive

[delicate stream]

Protip: don't be me, DO NOT hand carve your PCBs. It's dumb. Stop it.

[tardy badger]

So if anyone wants to sponsor Oak Dev @ $6000 a year lol

[delicate stream]

lol

That's my food budget

I'd starve

[late fulcrum]

Hand carve your own PCBs, you say?

[tardy badger]

Maybe my food budget but I’ll never tell 🙂

Nice filter

[late fulcrum]

Not quite a filter, RF energy harvesters

[delicate stream]

I mean, that's a simple one XD I mean with long winding traces... Imagine carving an Arduino Uno by hand

[delicate stream]

How much powah?

[late fulcrum]

On a good day, I could get the thick end of a microwatt

[tardy badger]

Ohhh nice

[late fulcrum]

Unless I set the antenna right next to a cell phone

[delicate stream]

What does one do with a thicc microwatt?

[tardy badger]

Thiccccc

What did you do with all that powah?

[late fulcrum]

You can see it taking about 4 seconds to accumulate about 60mV in a capacitor, at which point the energy harvesting chip grabs the power and transfers it to another capacitor. When the second capacitor is charged enough, the CPU boots up, does some stuff, and goes back to sleep.

I could run for about half a second a few times a day.

[delicate stream]

Or a couple seconds once a day!

[late fulcrum]

Then they wanted me to add WiFi. Um, there is simply not enough power available to do that. Then they wanted me to add cellular. That's in the realm of "there will never be that much power available"

[delicate stream]

Mechanical WiFi!

[late fulcrum]

When I put the antenna a few centimeters from a WiFi router, I could get a 60mV packet in a second and a half!

[delicate stream]

So what CPU do you use that can actually run on such low power and do anything?

[late fulcrum]

TI MSP430FR series

[delicate stream]

does a Google

[late fulcrum]

The non-volatile FRAM was a lifesaver too

[delicate stream]

I can imagine!

Oh wow, that's REALLY powerful and low-power at the same time

[late fulcrum]

There's a newer RF430FRL line that's powered by NFC, impressively power efficient.

[tardy badger]

Yeah, TI is pretty great at low power

[delicate stream]

I have a chonker MSP430 around here somewhere that I never learned to use...

[tardy badger]

Most all their LDO have incredibly low quiescent current

Like 30uA or less

[late fulcrum]

I found one hiding in a blood glucose monitor, a teeny coin cell about the size of a lentil powers it for two weeks.

[delicate stream]

Wowzers

[late fulcrum]

The energy harvesting chip was a TI one too: the other vendors' offerings needed like 300mV to do anything.

Here's the board from the glucose monitor: it's about 25mm across

[delicate stream]

How many RF harvesters would you need to power a Feather?

RP2040 version

[late fulcrum]

Rather a lot, unless you park one by a radio transmitter or high tension power line.

[delicate stream]

... would right outside of a big power substation supply a lot of usable RF power?

[late fulcrum]

The fence would probably damp out most of it, unless you held an antenna up over the fence

[delicate stream]

Hmmm... What if it's just inside the fence?

Guessing these are wide band if a fence will absorb it?

[late fulcrum]

Power substations (in the US) are 60Hz, not really RF: the fence would be a pretty effective shield at that frequency.

[delicate stream]

ah, I thought they did higher frequencies in addition to voltage for transmission...

[late fulcrum]

More and more transmission is moving to DC these days

[tardy badger]

60-120Hz depending on where it’s going and how for and what part of the grid it’s at

[delicate stream]

Yeah, I don't think they've done any DC work here tho

[tardy badger]

All MCU are DC

🙂

[late fulcrum]

I thought the Marvel Comics Universe was separate from DC comics?

[delicate stream]

XD

[tardy badger]

Technically DC is just AC that’s super stable and only has mV differences in amplitudes

Like 10s of mV.

[delicate stream]

https://tenor.com/view/hmmm-thinking-batman-gif-14744673

[tardy badger]

If you look at a DC supply on an oscilloscope you can see this

And the funny thing about crystal oscillators, they tend to produce more of a sine wave than a square wave

[late fulcrum]

The very high Q of crystals will tend to do this

[tardy badger]

Load capacitance helps tune the speed and shape

A line resistor will control the drive strength

But it’s all AC if you have a fine enough scope

[delicate stream]

Do batteries have any fluctuations?

[late fulcrum]

They're fairly electrically quiet, but not completely so. The terminal voltage also varies with the temperature and state of charge.

[delicate stream]

I can see a 60Hz ripple getting thru filtering on an AC-fed power supply, but I figured batteries wouldn't have anything consistent like that

[tardy badger]

The issue with PCBs is you can’t avoid cosmic background microwave radiation

Muahahahaha

[delicate stream]

https://tenor.com/view/jaiden-animation-gif-18484706

[tardy badger]

So you can inherit noise inadvertently

[late fulcrum]

There is the diurnal 11.6µHz ripple 🗓️

[tardy badger]

Plus with how polluted RF is these days, you’ll pick up some of that too

[delicate stream]

The what now

[late fulcrum]

Since battery voltage varies with temperature, and days are generally warmer than nights, battery voltage will tend to vary with the time of day: this has real world implications in that smoke detectors will tend to start their low battery beep in the middle of the night.

[delicate stream]

Oh, I didn't know there was a precise frequency of that

[tardy badger]

Ah makes sense

[late fulcrum]

It's just the reciprocal of the number of seconds in a day

[delicate stream]

ahh

[tardy badger]

Did you know that the three gorges dam in China shifted the rotation of the earth and slowed it down by a few milliseconds

[late fulcrum]

I did not, that's a little surprising to me

[tardy badger]

https://www.kinetica.co.uk/2014/03/27/chinese-dam-slows-down-earths-rotation/

Sorry it was microseconds not milliseconds

0.06uSec

[delicate stream]

I was gonna say, it couldn't have been THAT much, lol

1ms would be insane

[tardy badger]

0.06usec is still a lot all things considered

[delicate stream]

I mean, yeah XD

Anything we do that's measurable vs. the EARTH is a lot

But there's like... measurable vs. practically different

[late fulcrum]

There's someone at NIST with a title like "Controller of Earth Rotation" on their door: this sort of thing would be very relevant to them.

[delicate stream]

lol

[tardy badger]

Yeah haha

Imagine releasing the entire volume of the three gorges dam

I couldn’t imagine how devastating that would be

[late fulcrum]

Speaking of earth rotation, time for me to go to bed

Oh, weird pricing strategy. Got it.

https://tenor.com/view/trap-its-a-trap-star-wars-admiral-ackbar-gif-5740548

[weary fiber]

It's honestly frustrating 'cause they're so close to being great. Just tiny tweaks to the design + an open source would fix this for me.

With a better design & public dimensions, I'd happily overlook the cost & build quality 'cause it's such a unique product

[delicate stream]

Maybe I should do that so I can make more money than them by doing it better

[late fulcrum]

I can understand why they might be reluctant to go open source, but I agree that they should be more responsive, deliver the extra-cost quality you paid for, and it would be nice if they provided dimensions.

[weary fiber]

Yeah, I do feel like my open-source point is a little shaky.

[delicate stream]

Dimensions and fixing the problems at least

[weary fiber]

They're a small business (probs want to secure their profit line), and releasing the models would mean that anybody could print the parts at home for cheaper

But, counterpoint:

they could do what Valve did with the Index!

Provide CAD models, but ONLY of the bits that stuff would attach to

[late fulcrum]

While that would be useful for that subset of users that wants the info and can work with CAD models, it's a surprising amount of effort to do, and generates more customer support calls (even if they state the CAD models are where is, as is, and no support is provided).

Sort of like Canon refusing to provide interface details for their older printers. While it irks me, I can understand their point of view (my main beef is them lying about what operating systems their printers support).

[delicate stream]

Canon dumb

[late fulcrum]

Yeah, they put me and my 2000 (imaginary) listeners off buying their products in the future.

I did finally find a color printer I actually like, but it doesn't do metal foil like the accursed can't be used Canon (theoretically) does.

[delicate stream]

You have listeners? :O

[late fulcrum]

I claim I do when I'm talking to customer support lines.

[delicate stream]

lol

[late fulcrum]

Granted, there are probably a few people who read my blog or watch my youtube vids, but I haven't had actual "listeners" since my college radio days.

And occasional times when I show up in the news for various reasons.

[weary fiber]

(not meaning to argue, just sharing how it seems in my limited experience) I agree with you for 99% of cases, but this seems a little different. Kaiborg's main customer base is makers/craft-people, and that shows in how much of their website is dedicated to "print finishing tutorials". Combined with the STEEP cost, I'd at least expect SOME maker-focused dimensions/specs.

[late fulcrum]

I'd agree with that: dimensions/specs are a reasonable thing, I'm just thinking that an actual CAD model could be a bit much.

[weary fiber]

totally, and since they're a small shop, naggy customers would probably feel empowered to demand "I want the model in my specific format!!!!!"

[weary fiber]

also this is wild, what sort of stuff did they lie about?

[late fulcrum]

They claimed their Selphy line had MacOS support, but it was only partial support: the metal foil printing that was the printer's party piece was only supported for MS-DOS, and not well. I still have the printer and a bunch of media packs for it, that I can't use.

[tardy badger]

Testing more today on the Bread 2040 ✨

Tested all GPIO and works great so far 🙂

[late fulcrum]

Project Gutenprint does support that printer, but only in a couple of modes. I suspect the foil modes aren't terribly different (presumably additional color planes), but after renting an expensive USB analyzer and trying it with an MS-DOS machine, their software still didn't work and I was unable to get any data or prints, so now I'm out the cost of the printer, plus the media packs, plus the USB analyzer rental, plus the time, effort, and sanity the whole MS-DOS episode cost me.

I may eventually destroy the printer with my solar energy furnace and put the process on youtube.

[delicate stream]

"Any level of support on any platform counts as 'supported', right?" -- Canon

So my first 8TB Seagate HDD I plugged in immediately gave me a warning of 8 reallocated sectors DX

[grave crest]

Which USB analyzer did you rent?

[delicate stream]

Debating if I should test all 4 drives, or just immediately contact the seller... I'm worried because the bubble wrap around the drives in the box didn't really survive, so I'm worried it was shipping damage

[late fulcrum]

I honestly don't remember which one it was: it was a big chonky thing apparently designed for rack mounting, but not in a rack. Bigger than this one for sure: https://www.adafruit.com/product/708

Can you read the S.M.A.R.T. data from the drives? Meh, even if so, I would be chary of trusting those drives now.

I can walk for about 15 minutes before my phone overheats and dies. But I'm good for a couple of hours.

[delicate stream]

I almost had my main phone die

But not from heat, just low battery

[dusty citrus]

I wanted to make a peltier chips suit but they require 40 amps to lower temperature by 120oF

[tardy badger]

I take my dog outside and that’s about all I spend outside these days

[delicate stream]

Antique phone doesn't do so well anymore

[late fulcrum]

I thought of 3D printing an assembly to hold a Peltier cooler on my phone and blow air across it, but then I realized the PLA would melt

[tardy badger]

Aside from taking my kids to the playground

[dusty citrus]

It seems like if I do such a suit I'll get shocked by 40 amps and die

[delicate stream]

ABS yo

[tardy badger]

Acrylic?

[late fulcrum]

I've never attempted printing ABS

[dusty citrus]

The problem with peltier chip is the other side is cooler/hotter than the other side by a good factor

and all the amps required

[late fulcrum]

I don't think there are any Peltier that can do 120° (even the little F ones) in a single stage

[dusty citrus]

I don't have one but I heard of something like 180oC if the other side is cooler by 40oC

The ones I checked on digikey claims they can raise temperature by 60-70oC (150oF ish I think ?)

[late fulcrum]

But I'm just looking at a little one I can shove about 6 amps through into a heatsink + fan

[dusty citrus]

But didn't expect them to require so much amps

thiss one: https://www.lairdthermal.com/datasheets/datasheet-CP14-71-045-L1-W4.5.pdf claims to have a delta of 75oC

[late fulcrum]

That's 70.5°C when it's moving ZERO heat.

Still, I'm hoping to be able to remove heat from the phone fast enough that the phone doesn't shut down and stop when playing a demanding game on a hot day.

I used to be fascinated by fire when I was young

stopped when I realized my clothes would smell like smoked salmon for weeks afterwards

Also I once went in a fire to save a cat when I was 11yo which was pretty stupid

[delicate stream]

I love fire, but you gotta respect it

[scenic oak]

wonder if I can use model rocket igniters to light candles

[dusty citrus]

wasn't even my cat

[delicate stream]

Stupid, but brave

[delicate stream]

Lol, not for long

[dusty citrus]

The fire was small though but the fire department / cops were pretty angry

[scenic oak]

I just need enough fire to catch the wick >_>

[dusty citrus]

Also I never told the owner family it was me I just casually dropped it near them

They did the good cop/bad cop routine though with the fireman who had me visit the fire station with my dad after it was over (they had me stay because they had put the yellow tape between me going in and out) so they said I was part of the scene. And they especially spent a long time explaining all the protection they had against fire and how important it was etc

[delicate stream]

Oh, brain read "as candles" before... sure you can do that XD

[proven olive]

I've seen videos of popping balloons with overheating resistors

[scenic oak]

[ also now I'm running my test board over the safe current I calculated >_> ]

[dusty citrus]

is it true that capacitors can blow up with acid splashing if enough voltage/amps/watt are passed into them ?

[scenic oak]

I think I might actually be getting warm now

[dusty citrus]

we had an intro course to electronics in a physics course once and I had to physically stop someone from putting more volts into it with a bit of force because they didn't want to ask the teacher who had warned us before

[delicate stream]

You should get a FLIR so you know

[scenic oak]

I need to finish and sell this board and have lots of people buy them so I can afford a FLIR

[dusty citrus]

basic FLIR is around 800 us$ but like 200P

[proven olive]

Yep. It's probably not quite so dramatic but they can pop and with some force

[scenic oak]

I'm using the "stick my finger on it and see if it hurts" method

[dusty citrus]

I defended my actions by actions by saying I was afraid of being splashed by acid so I could use a bit of low self-defense and it seemed fine but the person wouldn't speak to me after that

i was a bit annoyed that the teacher had warned us about it 5 minutes before and they still did it

[scenic oak]

worst things I've done is burnt off a tiny bit of my fingerprint by touching the soldering iron tip on accident, and had an LED explode in my hand when I accidentally plugged into direct 3V3

[dusty citrus]

basic flir is basically 80x40 or something like that, very little range

[delicate stream]

You can get phone cameras [plug into your phone, Android or iPhone] at reasonable prices

[dusty citrus]

not worth it imho, better save for the 3000-4000$ models

[delicate stream]

I got a CAT S60 phone for $200, totally worth it

[dusty citrus]

that's fake though no? afaik phones don't have uv/thermal lenses. I mean if they do it's not even big enough for the law of physics

[delicate stream]

The CAT S60 has a FLIR camera built in. You can get FLIR add-ons for any phone with Lightning or Type C

[dusty citrus]

Just like my scale that claim to pass a current to measure fat in the body etc but the electrodes aren't even connected so it's just for the show and they just apply a formula

[delicate stream]

They're 100% legit FLIR modules

[dusty citrus]

I though you meant the apps who claim to do flir on normal phones

[delicate stream]

No, I said plug into your phone, lol

[dusty citrus]

but they just apply a random shader

[delicate stream]

You can get older models for cheaper, and they're perfectly fine if you just want to see hotspots on boards or know about what temp a thing is

[dusty citrus]

4800 pixels.... not much

[delicate stream]

You don't really need much

[dusty citrus]

that's like old hercules text screen of the 1980s, 80x80 pixels

I do if I want temperature measurement 5 miles off like A-10 thunderbolt II 😄 🤣

[delicate stream]

They don't make 14MP FLIR modules

[dusty citrus]

or 4 miles off like apaches

I mean the ones on civilians drones are 336 × 256

[delicate stream]

The modules aren't really meant for far off stuff, more for things right in front of you

Drones gotta have distance

[dusty citrus]

If I had money this would be my first purchase

[scenic oak]

that... is really not that bad

[delicate stream]

The nice thing about the module vs. the phone with a FLIR is that the module can move between phones, whereas with the in phone... Yeah.

I still have my CAT S60, but now it lives in airplane mode and serves only as a thermal camera and flashlight

[scenic oak]

although if I really want to abuse this board, I need a power supply capable of higher current output

because I maxed the power supply w/o maxing the FET specs 😦

[dusty citrus]

I've always been fascinated by electronics that were once military. At least you can talk about it vs if you are in the military you can't even talk about intelligence in the open because it would "confirm" it

Seeing things my eyes can't see is a general area I want to experiment with

[terse estuary]

I was always fascinated by the idea of radio "cameras"

I've seen a video where someone made a detector that could "see" in wifi. It was a somewhat directional wifi antenna on a motorized mount that scanned a few hundred points and made a crude image out of the relative signal strengths

Caveat being that it took something like 2 hours to make 1 image

https://www.youtube.com/watch?v=g3LT_b6K0Mc

[proven olive]

I've toyed with the idea of making something that'd be like that for magnetic fields, but it wouldn't be nearly as long range.

[delicate stream]

Anything is visible spectrum if you adjust your frequency range enough

[dusty citrus]

gota be careful with microphone in public in canada though because the law changed

spying/intercept when I was young like 20 years ago used to be is you used the information or communicated it to someone else

but now intercept is if you listen to a conversation with an expectation of privacy in which you aren't one of the intended recipient

[dusty citrus]

even neutrinos? 😄

with a large enough arduino I guess

[delicate stream]

A n y t h i n g

Owww, I just hit myself in the face with a bit of NeoKey Ortho

[dusty citrus]

my biggest electronics accident is pressing my case on my computer a bit too strongly to make it fit inside it's holes and the plastic(?) glass broke and sliced my hand

[delicate stream]

Oof

Oh, apparently there's a hurricane statement for my area, fun

[dusty citrus]

😦 can arduino help ?

[delicate stream]

Not this time

[weary fiber]

The maker of my helmet parts may not provide mounting dimensions...

But I have tape, string, and a pair of calipers

It's terrible & not useable for professional work, but at least this gives me a way to design an inner display mount

[real falcon]

yay reverse engineering

[dusty citrus]

This is what string theory is about 👍

[static flare]

Weird question, but does what I'm trying to convey with this come across?

[dusk oracle]

i really thought spi would have been more complex than "choose a CS line"

[static flare]

I mean, I've had difficulties with it in the past

[dusk oracle]

no idea what ur planning there

[jovial path]

@static flare Hi Xenia, what do you mean by convey?

[static flare]

This is an outline of the W from the Hollywood sign, just wanted to see if the biggest issue with how it looks is noticeable and obvious from the measurements

[jovial path]

I did not get it, can you explain in another way?

[dusk oracle]

ahhh

[static flare]

The left arm of the W isn't parallel, where the right one is, and the angles in the whitespace at the top is different, it just makes it look... wonky

[dusk oracle]

sounds like a warner brothers move

sadly havent ever seen the sign so i cannot be of assistance

[static flare]

It was originally put up as an advertisement for Hollywoodland, then the land was removed and they rebuilt it some time ago, where they kept the same mistake

[dusk oracle]

when your idea is to be disney land but all your tourists are actors

[late fulcrum]

Huh, that's the first time I've seen a 13V capacitor (this is in a turn signal flasher, so it's a bit underrated, as engine running voltage in most cars is 13.8 - 14.4V).

[jovial path]

It looks like masonry, I hate masonry, I never liked it, since I was a kid.

Once I bought 3 chemistry books online

My father actually, to me.

And the guy gave it for free (and they were expensive), I think because my father told him I was studying for one of the hardest exams of the country, etc.

When it arrived at my house there was a masonry card.

And then after a few time, I gave it away to others with the card.

I felt weird with the card. I did not liked it at all.

[jovial path]

Actually it is not hate, it is just I do not like it at all.

[proven olive]

Hey, I know exactly where that picture is from

[jovial path]

And I never will like it, or anything similar.

[late fulcrum]

I do appreciate youtubers with nicely kept fingernails

[jovial path]

And I will never ever participate things like these (masonry, illuminanti and all the others similar)

[static flare]

Such shock and surprise, I watched that video earlier today

Also, I saw an LGR video about in tower CRTs and I was curious if mine would fit, and the answer is yes

It's basically nearly exactly the right dimensions it needs to be, the only issues are power and video, it uses mains and composite, but that's not too much of an issue

[dusty citrus]

Can't wait for bioelectronics and being able to tune my cat with chips to generate revenues so they are useful for once

But knowing the feline conspiracy I know they already have contingency plans to prevent this

[jovial path]

Me and my father made this shelf, he bought the screws, the wood, made the technical drawing, and helped me a lot to precision parts in physical manufacturing. I used the drilling machine a lot in this shelf.

We just made it. It is not finished.

[delicate stream]

Cats are useful... You simply do not understand their ways.

This is to be expected of a human.

[dusty citrus]

I mean the tail is really great for a wifi antenna or an electromagnet

I wouldn't be looking for any projects if that was available vs some boring car kits all with the yellow extremely cheap wheels 😦

[delicate stream]

That cat with some fur would make the perfect spy

[jovial path]

I meant masonry.

This. I hate these things. ✅

[delicate stream]

Ohhh, that makes more sense, I thought you were talking about something else

[jovial path]

It is just an unfortunate coincidence that me and my father worked with wood and I said the word mansonry, it is not related at all. It is just an homonym word.

[late fulcrum]

Masonry in construction refers to concrete and brickwork. Carpentry refers to building with wood.

[wooden schooner]

do you have a reference for this?

I am somewhat interested in this aspect of biblical interpretation

[delicate stream]

And that was how the Adafruit Bible Study group started

[wooden schooner]

mainly in historical perspectives on how morality differed in past societies vs. today / each other [edit: apparently this is called comparative ethics]

[dusty citrus]

"I am the AdaFruit, the beginning and the end. I will give unto him that is athirst of the electrons of the electricity and magnetism, at reasonable price and we ship to Canada."

nice library.

[tardy badger]

It comes from the words used for “honor” which translates roughly to meaning “to bring high regard or respect”

[wooden schooner]

Ok, sounds like you're working in English in modern times, not, e.g., Hebrew many centuries ago

Iirc, even child rearing manuals from the early 1900s are pretty straight-up obedience oriented

[tardy badger]

I’m going off of the rough Aramaic to English translation

Obedience and honor are not the same in ancient Hebrew or Aramaic

[wooden schooner]

Nice, I'll look it up but, do you have the words on hand?

[tardy badger]

Here is a pretty clear article on the topic from a Jewish perspective

https://jewishjournal.com/commentary/opinion/86981/

[wooden schooner]

Oh man that article looks great. I was expecting a modern interpretation but this person looks willing to ruffle some feathers

And I see the word is kbd (apologies for the terrible improvised input method)

Thanks!

[tardy badger]

If you go mostly on the opposite of honor in the original tongue, you see it’s to curse

You can identify the context isn’t necessarily to be obedient but act in a way to be honorable and respectful in way that “adds to their health”

[dusty citrus]

^you guys are jewish ?

[jovial path]

I love jews 🙂 they are so similar to christians.

but I will not talk about religion.

[dusty citrus]

nah didn't want to talk about religion it's just the last time I asked that IRL it became awkward as if I was going to say something offensive next when I was working in a convenience store. I could see they wanted to know something about the coffee but wouldn't dare to ask.

So I just pointed the coffee was pareve and they really opened up and we traded so I could get a few shekels (didn't have any in my coins collection back then) with me getting a good value I guess

[delicate stream]

People can be weird... I don't think there's anything wrong with talking about religion, just fighting over it. It's all good if both parties are seeking knowledge and understanding of the other's views

[dusty citrus]

and it reminded me of that, they though I was jewish but I explained it I just know a lot of things and knew what they were looking for 😄

[delicate stream]

Lol

[dusty citrus]

could see a big breath of relief when they realized the interaction would be positive

[delicate stream]

I think Jewish folk can be more in guard because they tend to be targets more than, say, Christians

At least in certain countries

Or certain parts of certain countries anyway

[dusty citrus]

only one i could find quickly

[delicate stream]

Oh, cool

I love coins

[dusty citrus]

We used to have open hannukah here until certain incidents and the local community is now much more guarded

[delicate stream]

Half value coins are fascinating

[dusty citrus]

I tried to reach because I had questions about the torah and wanted to ask questions but now you almost need a referral

[delicate stream]

That's a shame... I had thought about going to a temple a couple years ago to ask some questions, I guess I might have met resistance on that

There's a synagog on the corner of my street, and they've been vandalized a lot over the years, it's a great shame

[dusty citrus]

yeah same and now they have security close and watchers ahead of the way

[delicate stream]

Mhmm... They have someone in the building 24/7 from what I hear now, cameras all over

Whereas Christian churches are popping up like wildflowers, people literally going door to door looking for new congregants

[dusty citrus]

Yeah I don,t want to convert though just interested about the country and the why of some policies and understand the torah more

[delicate stream]

Yeah, I'm generally curious too. I've studied other faiths on and off for decades, just because I like to understand different people and cultures

[dusty citrus]

I also find that if you says you follow all abrahamic religions peoples have no ideas what to argue about 😄

[delicate stream]

Lol

[dusty citrus]

Because almost nobody expect that

[delicate stream]

Well, I'm off for a walk... TTYL!

[dusty citrus]

[jovial path]

There must be so many great and rare books there.

Electronics engineering books...

They should put all these books online ✅

Actually all libraries in the whole planet should put all books online.

For example, simulate the of borrow books online. Like 7 online books avalible for every title and you can keep it for a week.

Then you treat books like physical ones.

So the author could still receive a bit of money selling books.

[delicate stream]

Nice thing with digital rentals is they can be automatically revoked instead of potentially lost forever like physical books

[jovial path]

Yes, but only 7 books avalible to each title to everyone, to get it when there is 0 books you'll have to wait.

[delicate stream]

Yeah, I don't think that artificial scarcity isn't something I've seen... Certainly an interesting idea for a library

[jovial path]

It is great so it can protect the work of many author.

[delicate stream]

Not sure about that... If it's digital and available, it's rippable.

[honest jolt]

I think digital libraries have to pay a license for each copy of the book, so if you limit a book to 7 people at a time, the library pays for 7 copies essentially

[tardy badger]

Ah yis

PCBs

[jovial path]

I do not think libraries keep paying for the authors as there are people taking books.

The idea is to literally simulate a library.

[jovial path]

Then no downloads, you can only read online.

[honest jolt]

Not keep paying, it's like a physical book. The library pays for 7 physical books and people lend them. Same for digital - the library pays for 7 "licenses" then they can loan it to people

[jovial path]

I have been using study groups like this a lot in COVID, it is pretty great. Sometimes a lot of people turn on the cameras and we see each other studying. The chat is usually very active in the study breaks. Pretty nice.

[dusty citrus]

Did I ever tell you guys about my amber alert when I visited manhattan ?

[velvet pelican]

I know libraries here have online versions of books that you can read in browser and such

[delicate stream]

It's pretty easy to do screen recording and pull characters, but there are people who steal anything that's not nailed down

[jovial path]

I'll stay on for all night long....

[delicate stream]

So I did a dumb... Connecting Ortho snap-apart bits back together, forgot they zig-zag for the NeoPixels... DX

[static flare]

ohno

[delicate stream]

Yup. But I think I can adjust in software, I'll just have a wire running from one end of a row to the next

[delicate stream]

https://tenor.com/view/magic-smoke-blue-smoke-gif-21971535

[tardy badger]

it works! hazzah!

[wooden schooner]

oh nice. So that's an LED array that uses an RP2040 as the driver, which is overkill but it doesn't matter because the RP2040 costs pennies?

[delicate stream]

I thought RP2040 was always $1

... Although skerr getting them for less and selling them for $1 a piece would make more sense than at cost sales

[proven olive]

technically $1 is still 100 pennies. But yeah, as far as I know it's always $1

[wooden schooner]

is it that RPi is intentionally eschewing a business practice (bulk discounts) that companies typically use to turn a higher profit?

[tardy badger]

I mean they cost me $0.50

Well, $0.56 if you include shipping

[tardy badger]

It also has some Stemma QT for sensors

[proven olive]

What sort of hoops do you have to jump through to get that sort of price?

[tardy badger]

Order a minimum of 500 pieces from RPi directly

[proven olive]

That's not bad, only $250 there

[tardy badger]

Yeah, then $30 shipping internationally

[proven olive]

International shipping for $30? Also not bad

[tardy badger]

Yeah, it was a pretty sweet deal

But it was an 8 week lead in those 500

Longer leads on the 3k4 reels

[proven olive]

Heh, get some from Digi-Key for your prototyping, and then from RPi for your production.... and then later prototyping since you already have a pile

[tardy badger]

Yeah, I started with free samples from RPi back in March

Then ordered a reel in May

[delicate stream]

Oh, good, so I'm not taking money out of your pocket if I buy them from you XD

Is the iPhone 5s worth repairing and using in 2021?
Use case: phone calls, video calls (maybe), WhatsApp/Telegram/Slack/Discord, casual reading, time killer arcade games (maybe) and other basic smartphone functions.
I love the small form factor but am too broke to buy the iPhone 12 Mini or the iPhone SE. Also, I want to try out iOS, being a long time Android user.
My only apprehension is whether they still do any software updates and updated versions of apps even work, and the hardware's capable of daily driving.

[finite horizon]

hardware is alright at that stuff, device no longer gets updates tho

most apps will support the resolution but there wont be security updates

prolly for the better tbh

dont want apple snooping around my messages and images by force

[blissful roost]

iPhones aren't worth using on release, so.... Rhetorical question?

[delicate stream]

If you have one already... Depends on the issue. Battery? Sure, cheap enough. Anything else? No, you can get a refurbished iPhone 8 for a reasonable price -- still gets updates, faster processor, I think a higher resolution screen... Just better. I got one for $200 like a year ago

[jovial path]

I love this device a lot.

Decades ago, I managed to do the same. The friend with me came back over to me, and was like "Whatever, you just stubbed your toe, everyone says they broke it......" and then looked at my foot, and stopped short. My toe was also entirely dislocated. I broke the third bone from the top. 🙄

2nd dose started osteoarthosis for me, basically pizer can cause joint pain so it started a flare up. Public health didn't take the report because they already knew it could cause that and transfered me to a nurse. From discussing with doctor it's probably trauma related due to playing soccer 10 years ago and having to stop because of a stupid collission during a low intensity practice with a barrel

[tardy badger]

Yeah, joint swelling and pain is pretty common for covid vaccines and most vaccines really. I’ve never seen it extreme but definitely something to keep in mind

[dusty citrus]

Was extreme for me unfortunately 8/10 on my personal pain scale. Was 3 weeks ago and now I don't even need the painkillers anymore

[tardy badger]

I’m glad it wasn’t worse than 8/10

Unfortunately it’s impossible to avoid side effects with medicine and vaccines.. but at least for a vast majority of people things are relatively mild

I’m expecting round 2 to kick my butt

I have Ehler’s Danlos Syndrome so I’m anticipating bad joint pain

[jovial path]

Some GSM(smartphone chip companies) , I think, all have nice programs to non-rich people like me. I can use internet's WhatsApp for free forever.

So I can make video calls, etc...

There are also some other apps that may be included like Facebook.

So I can use the 4G for free.

It's great in possible emergencies.

Or who knows what.

[jovial path]

For these special apps.

[jovial path]

There are 4 Chip companies here in Brazil: Claro,Tim,Oi and Vivo. I think all have this program. You just need to buy an about 2 dollars chip and it is open to everybody.

[dusty citrus]

Pro-tip: When it's free or extremely cheap, you are the product for sale

ie: your personal info, so don't be naive

I stopped participating to sweeptakes on food because I know they sell off my info for 6-7$ while I get 1/1m odds to win anything

For that price I,d rather have a chance at winning over 1m$ or even the above 50m$ jackpot and not be worried to sell my info to dangerous scammers

[jovial path]

these companies are not close to the best chip companies in the world

or close to the last

[wary herald]

So they're in the middle??

[jovial path]

They can not be all in the middle.

And possibily if there are a pair number of smartphone chip companies, there is not a company in the middle.

Who needs PIO when you’ve got a whole damn core? Running a HUB75 display from a @Raspberry_Pi RP2040 Core1 clocked at 300MHz because why not?

Core0 is handling the per pixel HSV to RGB for this effect. https://t.co/F5ZzGoKCy5

You know, I really ought to try and make a Doc Ock costume at some point.

I tend to go to cons with a backpack full of photo gear and I could just mount the arms on the backpack with a cover.

I mean

Ill make a logo for you for free

And you dont have to give me a board

[tardy badger]

Not a logo

[pearl zodiac]

oh ok, I am barely just now reading it

[tardy badger]

Just a fun sticker

[pearl zodiac]

Elaborate

[tardy badger]

Something that’s electronics focused and has the letters “ODT” on it

[pearl zodiac]

'sticker'

like a colored, animated GIF type sticker

or like, a single color vinyl sticker

digital sticker

analog sticker

etc

[tardy badger]

Physical sticker like you would put in with physical product you sell as like “goodies” or marketing type stickers

[delicate stream]

Nice!

I have saved approximately $100,000 by finding discarded eCigs and recovering the batteries from them

Dunno what to do with the sensor thing and heaters...

[late fulcrum]

A surprising variety of throwaway items contain concealed rechargeable cells

[delicate stream]

It's crazy!

[late fulcrum]

The heaters are useful for cosplay fog effects

[delicate stream]

And a lot of eCigs are like, 400-600mAh!

Ohhhh, fog... I didn't think about that!

[delicate stream]

Any guides to do this?

[late fulcrum]

Presumably, but I'm not in a position to check right now

[delicate stream]

It's cool, I need to go to bed anyway XD

[burnt tendon]

...if you wanted to cosplay as Cloud Computing, $100,000 worth of discarded eCigs would be a good start.

[real falcon]

sensor and heater = make micro printer 😉

[dusty citrus]

@real falcon what about motors and all that jazz? you mean print with our bare hands?😅

[real falcon]

yup. or maybe just 3d pen lol

[dusty citrus]

i like it! though whoever 3d prints by hand could have fumes go right their way, so ventilation is a must.

[real falcon]

yeah not issue with pla or petg, but otherwise yeah

[wary herald]

🤣

[wary herald]

I never thought of that!

that's a good idea

[dusk oracle]

my brain is in overload..

so i designed a handheld with video out and a few io extra's for expansion.
i opted for a esp-pico d4 with a popular 320 x 240 lcd.
but i made sure i can decouple data lines using a trick with powering down a cheap level shifter.

so far graphical performance is good and using the spi ram is a life saver.

however now i'm looking at the sound and the dos sound blaster era leaves much to be desired in terms of audio quality and speed.
someone suggested i try a find a cheap popular midi synth + mp3/aac chip to handle music so the DAC can focus on playing samples while the the audio chip focuses on playing music and freeing the cpu from this task or even a chip that can handle samples.
however i feel this is overkill unless i can find a popular chip.

[delicate stream]

I'm exaggerating a little, but yeah, they're all over! Just avoid ones that look like they were flattened, a lot of cells have damage. Dented can be okay, just be careful!

[jovial path]

@dusk oracle enginoob here, i vouch for separating audio processing from your board to do video and so on. i work with game maker studio and they set it up similarly where the audio engine runs alongside the sandbox. couldn't help but see that correlation lol

@dusk oracle here is a board that might help? https://www.adafruit.com/product/1381

Just heard a loud lightning strike that shook the house, and now I don’t have power

[blissful roost]

Oh dear

[tardy badger]

Welp

[supple surge]

I had that one too and it always blew my mind!!! Especially when everything else around me was windows xp haha it was SIRI before SIRI 😂

[late fulcrum]

I had that a few months ago, after the lightning arrestor on my pole failed and hadn't been replaced. Lost a phone, phone interface, television, TiVo, DSL filter, and computer speakers.

I was able to repair the DSL filter.

[supple surge]

Gonna see if I can circuit bend the audio output, maybe replace a few LEDS with different colors, I do see some vented cap fluid so, some cleanup haha, and maybe a hidden stemma magnetometer or Hall effect to bounce the spin data to a nearby qt pi 😅

[jovial path]

It is very rare lighting strikes where I live, but I was reading about lightining rod a few months ago. A university put a lot of different lightining rods and a fuse(to detect the lightining. Creative) to test what shape of lightining rod was the best to be hit by a lighting strikes.

There was a lot of very beautiful equations in the article.

Since Benjamim Franklin (the lightining rod's creator) lightining rod is quite the same.

In the end there was a shape that showed to be the best lightining rod, but not so much better than the others. And of course I can not ignore other natural factors that could have made this "best lightining rod" the "best lightining rod" of the text.

[viscid hamlet]

hello everyone i am new to this discord as well as in electronics so i would like to know what are good electronic projects with only tht components (I already made an audio amp )

[jovial path]

You should buy a lightining rod.

[delicate stream]

Unfortunately that won't save you most of the time, usually it's lighting hitting transformers or power lines elsewhere that cause outages

Hehehehehe https://www.tomshardware.com/news/raspberry-pi-long-log-pcb

[tardy badger]

Lol

[tardy badger]

What you need is a grounding rod pounded 2m into the ground

A large one too with chonky wire going from your box to the ground and a large ESD ring on your I coming line

I had one job where basically all I did was pound 1.5m grounding rods into the ground and then attach a 2’o wire from the rod (buried 6” in the ground) to the metal frame of a natural gas well meter building

[late fulcrum]

Right: a "halo" or "Ufer" ground with multiple grounding rods and a low-impedance path to it (6 inch copper sheet is good for this), along with spike suppressors (Polyphasor sells some good ones) on all the cables going into a building, will let you operate and your equipment survive even a direct lightning strike.

[delicate stream]

That doesn't help if the transformer 2 blocks away gets hit XD

[tardy badger]

I mean, it’ll help not fry your panel in those events when it sends a massive surge down the line

[delicate stream]

That's what the line surge buffer outside is for, they have them on the pole for each house

[tardy badger]

Never hurts to have more

A lightning strike messed up my AC for like 10 minutes

[delicate stream]

RIP

Well, I've got the big line buffer outside, chonk main breaker, line filters on some lines inside, power conditioners on certain lines, UPS for all computers and equipment, as well as surge protectors.... I might be overboard already XD

[lapis bluff]

I had a strike here. I was at the computer late at night, it went flash; bang; black, faster than I could type that, although a little slower than displaying it. I was sitting here at my computer and the sequence was: all external windows lit up brighter than direct sunlight, then a bang that rattled all the windows and shook the house, then the lights went out (it technically wasn't full dark, the computer and monitor were on a UPS); all in a fraction of a second. I was the only house affected, so when talking to the electric company it wasn't an "emergency" so they put it on the next days "urgent" list. A tech showed up the next morning and showed where he could see the evidence of the strike, it had blown the fuse to my house, but before he reset it he had to check that the ground wire it had followed to "earth" was still good.

[jovial path]

@late fulcrum @viscid folio @night crescent it maybe beautiful in design?

[delicate stream]

I partly lost power this morning when my mom uses her hair dryer... That, a 3D printer, AC, and a computer were too much for it, lol. Thankfully the computer and printer were on a UPS

[dusty citrus]

sweet! are you using two separate 5x6's?

[delicate stream]

Three of them XD QWERTY, broke them to do a standard layout, full numpad and all

[dusty citrus]

i hope to see a pic sometime 😀 the usually empty space between the arrow keys and home/end/etc is begging for 5 keys, almost like another numpad

[delicate stream]

I'm thinking about bringing the arrows against the right side letters part, then squeezing the whole PrntScrn/home/end/pages all into a x2 segment there

[dusty citrus]

that's a lotta keys! i hope to somehow swap or rewire my kb's "function/fn" key for something else.

[delicate stream]

I think it's gonna be ~120 keys

[dusty citrus]

oh ok. sounds awesome nonetheless. best of luck!

[delicate stream]

[dusty citrus]

hey i remember you were looking around for custom keycap places the day i joined. did you get your caps figured out?

[delicate stream]

I think I'll need to print and/or cast custom

[dusty citrus]

oh sorry to hear! well not to judge, just a lot of time and effort instead of asking for it done is all. did you print any caps? sorry if i'm being nosy! i should be working anyway 😅

[delicate stream]

Lol, it's cool. This is entirely a "because I want to" project, I just want the experience XD I have printed some caps, made some optimizations, so I could print a full set if I needed to. But if you need to work, you should work :P

speaking of may i ask where these memes are from? is there a sort of memehub?

never got into them to be honest. but i can animate stuff so if they can be uploaded custom, dunno why i haven't made some

[delicate stream]

I just use GIF search in Discord, and know the ones I use by exposure or they're close enough to my keyword search and I like them. That one is called "this is fine". KnowYourMeme can tell you a lot about memes

Memes are... Complicated. Most are spread by someone initially creating/sharing, some people like it, take it, share it with friends, maybe tweak it, rinse and repeat many many times over

[dusty citrus]

lol ok, thank you for the meme help! never noticed the search bar up top til now..

and what's this gif button at the bottom here do?

[delicate stream]

Haha, you're welcome. I speak meme pretty fluently

[dusty citrus]

so it looks like one can't upload their own gif, only searchable from the built in repo?

[delicate stream]

You can upload to Tenor or Giphy or whichever one you're using, but not within Discord

[honest jolt]

You can upload .gif files to Discord as well but they won't go to Tenor/Giphy, they stay on Discord servers. They also have to stay under file size limit.

hey guys, question, what jobs do you guys think are suitable for fresh EE graduates?
im currently job hunting to fill in the time, but most of the jobs are either being industrial technicians, repairmen, or supervisors
The reason why they're not really what im looking for is :

1. i have no experience or knowledge on industrial machinery
2. i have made a vow to myself in front of others that i won't be stuck in some dirty repair shack cuz it looks so depressing
3. supervisors are a high levelled job, i dont have experience in that

no offense to those in the repair field tho, sorry

In my house, tables is shelves... IKEA LACK tables are amazing. $5-15 depending on sales, stackable, light-weight but rather strong -- perfect for stacking to make shelves, or a taller table with storage for a 3D printer, or even an enclosure if you print some brackets and have some acrylic!

[quartz wren]

just mangled a pico

still works

uploaded blink to test it and it's happily blinking away

no clue how as I had a razor blade between its layers on accident

[delicate stream]

Oof

Working good tho

[quartz wren]

yeah it looks like the razor blade barely went in, but from the angle I was trying to work it off the board from, it looked like it sliced halfway through the board

but uh...I had it anchored on one side with loops of wire....

that were soldered in

with another pico on the other side that they were also looped through

so yeah...nasty bit of rework but I should still be able to use this pico maybe

at least the USB host pads are fully intact

if nothing else I can use it as a test bed for abusing the pico

it clearly can take the abuse

will get pics of how the module looks when I get to my phone (it's out in my shop)

[delicate stream]

What were you doing with the razor anyway? XD

[quartz wren]

luckily the other pico managed to escape unharmed even though I had to get a razor blade between the one I mangled and the board they were both attached to in order to cut the loops of (solid core) wire

initially I was using it to get between the pico and the board while desoldering as I don't have any solder wick or a solder sucker or a desoldering iron

because the other side of the pico was just surface mounted

if I had solder wick I could've just wicked the solder from around the loops and bent them out straight again but no

it kept pooling because surface tension and I couldn't get enough purchase to bend all the wire loops out

so the razor blade it was

at which point I said screw it I'll just mangle this pico to save the one on the other side

but they both still work so I'm happy with the result

[delicate stream]

Working good XD

I just took melatonin to fix my screwed sleep schedule

Probably not the best idea. But melatonin...no way it can be harmful right

[wooden schooner]

That is the most common use of melatonin supplements afaik, and very much not harmful

[delicate stream]

You'd need an insane amount to be harmful

[wooden schooner]

To kick the sleep schedule back into place I'd recommend 3–5mg, for regular use / trouble sleeping perhaps 1mg

Afaik, doses higher than 5mg are just not useful

[delicate stream]

I think it has to like 100-1000x that to be dangerous

[wooden schooner]

(Also I'm not a @delicate stream, ask your GP 🙂)

[delicate stream]

Yeah, ask your GP what dose is right for you. Many people are in the 0.5-5mg camp, but some need like 10mg or more... it CAN really screw your sleep cycle up if you take too much, but that's really about it unless you're taking very high doses for a long time [which isn't really well researched]

[wooden schooner]

I recall hearing that most effective dose range according to most studies is less than 1mg, but the OTC supplements are more than that because of some stupid patent thing. Do you know if that's true?

[delicate stream]

Not sure -- I haven't looked too much into it, I just know it can be highly effective and usually only needs a low dose, but usually more than 1mg on average from what I know

[wooden schooner]

I take 1 gummy (i.e. half the recommenced dose) of Olly Sleep ~every night. That's 1.5mg melatonin and 50mg L-theanine. For some reason, the gummy seems to work better for me than taking the same quantities of those things in pills.

I've also had great results with Neuro Sleep (melatonin + L-theanine soft drink), but that's more expensive

[delicate stream]

Might be the delivery format? Some things will absorb better into your system

Welp, designing a case for my broken watch... Thought I had measurements right, but I was 2mm off, somehow... Despite using calipers XD

[dusty citrus]

drat, sorry that's the case 🤔

no pun intended

maybe a noob question, do calipers need calibration once in a while?

[delicate stream]

Lol. I don't think so -- mechanical calipers can't lose calibration because they're basically just slidey sticks with lines, and digital ones measure from whatever reference point they start at, not sure if the sensor can lose calibration...

[dusty citrus]

oops i assumed something digital about them 😆

[delicate stream]

lol

[dusty citrus]

i was so happy when mom handed me down her calipers i didn't know she had. until i tried using it! the measurements begin in a really odd place, not where the object rests against one of the clamps, but like 15mm down the thing. i'm like whyyy?

[delicate stream]

Maybe they were specialty calipers? Some are calibrated so the 0 mark starts somewhere else because there's a base measure that's always being used

[dusty citrus]

i guess they are specialty. i'll have to ask her if she knows what they are meant for. thanks doctor!

[delicate stream]

No problem :D

So I think I got it now... Just gotta wait for the v2 test to print. But that'll be for morning me to see. Thankfully I don't need to be exact for the final either -- going to be printing the final version in TPU, so it can stretch if I'm a bit off

[wary herald]

Sure

[quartz wren]

CRT out of some old optometry equipment and an ammo can so far, still have to mount the PCB inside the can but the tube mounting is finished

[wary herald]

Ooh, fun

[quartz wren]

going to drive the beam directly from a Pico with PWM for intensity and 16-bit DACs, loaded 8 bits at a time for X and Y deflection

[wary herald]

That's a good idea

[quartz wren]

then I'll normally have my input signals get sent straight to the vertical deflection when in oscilloscope mode and because I am driving the beam directly I can do raster mode, oscilloscope mode, or vector mode

but then if I want to sample something into memory it will route through the Pico's ADC's and back out through the vertical deflection buffer

and if I just want to display it, I'll have the beam sweep trigger on a programmable voltage after the beam has finished sweeping

[dusk oracle]

Wow now thats fallout material.

[quartz wren]

indeed, it even has the middle of the vault tec logo burned into the screen haha

not from the actual logo, but from the targeting circle it had while in the equipment it came from

[static flare]

@dusty citrus what do the calipers look like?

[dusk oracle]

😂

i did some thinking on my console.
and i decided she needs one more thing next to the audio.

[quartz wren]

oh and if I get it working right, I can get this to display a monochrome VGA signal with the beam sweep controlled by the pico reading off the sync pulses

[dusk oracle]

i decided i'm going to make a open source gpu ala ps1 style..

[quartz wren]

(originally was composite input)

[dusty citrus]

@static flare not sure, the ones in question belong to @delicate stream but best guess is @wooden schooner 's pic above
