Luckily the townhouse I live in uses manufactured floor trusses

Downside is there is a double top plated 2x4 wall holding up a decent section of floor trusses

And it makes me nervous

It’s okay though, the quadrupled one part of it

[ebon dew]

You spent time making that in CAD.... lol. Was worth it. Had me laughing.

[rapid geode]

you can cut top plates if you tie them back together with steel plates.

often has to be done for plumbing stacks

[ebon dew]

That will make any future runs into those wall cavities surprisingly long. If I had to go through 2 I'd start questioning myself.

[rapid geode]

also need a steel guard if you drill too close to the front (to keep screws form hitting the wires)

[tardy badger]

Personally, if I had the kitchen floor sitting on 2x4 walls, I’d be a little nervous

[ebon dew]

Holy cow and the 4 vertical 2x4's. Well it looks strong there.

[tardy badger]

The kitchen/bathroom is right there. And another story up is the laundry room

[bright veldt]

thoughts on openROAD?

[tardy badger]

If i showed the whole wall, you’d see the double plate sagging a little bit

[ebon dew]

It is weird i have a desire to drive a huge lag bolt through those?

[tardy badger]

It can be tedious to set up. Fairly popular though for semiconductor development for OSSC

DJ, I really got "in the weeds" on this - new class code for me.
Putting a list into a class.
I have Pycharm which gave me some tips. Still learning Python and it's still fun. Attached is my new test code. This is working but I'm not aware of a "better" way to do this.

[rapid geode]

yes

screws and bolts are usually not used in normal houses.

unless it is engineered components

every joint in a house is in compression or shear. never in tension.

[late fulcrum]

Manufactured trusses are dandy (I like the nail plate variety). However, manufactured lumber (like glue-lam) is something I'm wary of.

[rapid geode]

glulam is amazing. used a lot in BC. 100+ foot beam spans, so pretty

trusses are cool, but they have one main issue which is you can never make any modifications

[late fulcrum]

I just figure it'll turn to mush if it gets wet

Wow, looks like a TV show I used to watch, but I think it was filmed in the UK

[rapid geode]

im not sure if they film anything there.

they did have a film board trying to get shoots

[ebon dew]

it's beautiful. i love the design.

[rapid geode]

oh.. "reindeer games" was shot in the town, but i dont think at the shool

yeah its a nice design. big sweeping areas. the stairs are scary

the other thing i like is CLT panels

they are building a 12 storey wood building form it there

(this is prince george canada, a big hub for lumber mills, pulp mills, forestry etc so they promote and fund a lot of wood projects)

[ebon dew]

Hand rails on glass. what could possibly go wrong.

[rapid geode]

nothing. but i would sit on them...

haha

[ebon dew]

it would make falling down the stairs much more dangerous. turning a bad situation into a worse one.

[rapid geode]

[ebon dew]

I'm not a fan of sacrificing safety for aesthetics.

[late fulcrum]

What would make them safer? More landings? More handrails? More padding?

[rapid geode]

yeah i think its just your perception. nothing unsafe about it

[late fulcrum]

You did say "the stairs are scary", I'm just trying to figure out why

[rapid geode]

just to look at

[ebon dew]

stairs are safe, it's people that aren't.

ive made a robot arm before...

well, not a real one

cgi one

haha

[stable bobcat]

something like that 😛

[rapid geode]

ahh

no

[late fulcrum]

I've built a couple from kits. Currently working on a walking robot.

[stable bobcat]

wow nice

[ebon dew]

Looks like the base uses a slip ring. That's a really nice design.

[ebon dew]

Looks like a crab. I'd be interested to see how it walks. Is that a quadcopter base?

nvm I'm going to guess it's custom made since one leg is blue.

[stable bobcat]

oh this is like a google quick exemple thats just a curius question

[late fulcrum]

Yeah, my own design, 3D printed out of whatever filament was loaded when I was trying that particular part.

No real slip rings, I'm using the servos as hinges

I made a 3D model of a servo horn and subtracted it from the leg for solid engagement

Another view

[ebon dew]

Oh for the slip ring I was talking about the reticulating arm base WaLasy posted.

[late fulcrum]

Yeah, that is nice

[ebon dew]

I've seen people make those kind of arms for DIY pick & place. When done right they can help with production runs. I want to say Winterbloom made one but don't quote me on that.

[ebon dew]

Oh very nicely embedded servo arm. Those are some thick legs. Surprised those servos can move all that weight.

with the base and electronics i mean

[late fulcrum]

They're pretty light (not much infill on those prints)

The thickness is basically to accommodate the thickness of the servo horn

[patent hemlock]

aaaannnd here's one reason i'm glad i can rely on transit instead of driving -- Tesla recalls nearly all U.S. vehicles over font sizes on warning lights

[rapid geode]

font size?

how come they can remotely disable your car but they cant remotely update a font?

[smoky hull]

Adabox!? https://learn.adafruit.com/adabox021/introduction

[late fulcrum]

It's an over-the-air update, but legally it qualifies as a recall, even if you don't have to move the vehicle to a dealer to get it addressed. However, IMHO the font size problem pales in comparison to the general problem of having to control things via a touchpad. Luckily there are a few manufacturers of EVs that offer physical controls a driver can safely operate without taking their eyes off the road. Tesla is not one of them.

[rapid geode]

ah ok

evs often get used as an excuse to dump a whole lot of junk into a car. then epople "blame ev's'

but theres no real reason an ev needs to be any more complicated than any gas car

[glad ruin]

From a user standpoint, yes.

[umbral phoenix]

touch screens take your eyes off the road, but also accumulate fingerprints and sometimes it's tough to hit the targets when the car is jostling around ...so much easier to handle a tactile control blindly

[rapid geode]

im really surprised the panel in a tesla is legal at all

[late fulcrum]

A lot of carmakers like touch panels because ... they're cheap

[umbral phoenix]

very distracting too... so much information displayed, and typical UIs are not very good

[rapid geode]

ui a bad. tactile is bad.

[late fulcrum]

I'd argue that tactile is GOOD.

[patent hemlock]

there's been recent studies (and trends) to re-introduce "manual" controls like buttons simply because of the distraction factors associated with the touch screens

[late fulcrum]

When we bought our toaster oven, the one we chose was more expensive, but we liked the big knobs and simple display better than the cheaper options offered.

[tardy badger]

I dislike that I can’t adjust my air without looking

[late fulcrum]

For me, it's more than a dislike, I consider it a safety issue.

[tardy badger]

But most every car brand is still doing the move to screens

[tardy badger]

I dislike it because it’s a safety issue

[late fulcrum]

Fair enough. I just thought "dislike" wasn't a strong enough term.

[glad ruin]

There is very little oversight on car designs here in 🇺🇸. We have emissions regulations, but that's about it.

[tardy badger]

Many companies try to cheat emissions regulations anyway

[late fulcrum]

See Technology Connections rant about turn signal colors

[tardy badger]

coughs at cumins

Cumins recently got hit with a $1.6b fine for trying to cheat diesel emissions

[tardy badger]

Yes, I dislike how some do mixed stop/turn signals lights

When that light goes out for the brakes, no turn signal

[glad ruin]

Basically, all of the automotive safety regulations and such are industry controlled/tested. Sort of like Boeing with the FAA, but no FAA.

[late fulcrum]

In Europe, brake lights are always red. Turn signals are always orange. It seems to me like a Very Good Idea.

[tardy badger]

Or they make the turn signal so small that it’s difficult to see during daytime driving

[late fulcrum]

I like Volvo's big bright visible turn signals (although in the US, they're red)

[tardy badger]

I kind of like how Chevy had where the headlight on the side for turning would turn off when the signal was activated. Seemed like it made it obvious

I think it probably could have been executed a little better than just turning off the headlight, but it at least made it obvious from a head in view

[tardy badger]

It’s wild how companies with incentives to cheat, help formulate the very laws they end up cheating

But it’s really just to make it more difficult for smaller companies to even get started. The regulatory framework ends up being too expensive to try and comply with.

Meanwhile Boeing has had.. how many groundings over the last 5-7 years due to corner cutting..

I’m glad companies like Adafruit exist though

I love the “cooperation is better than competition” mindset

At least in terms of their support for small businesses and such

[rapid geode]

its bad because it requires you to look at it and concentrate on what you are pressing. and it has no feedback. for some uses touch screen is great, but for a car's main systems? mmmm.... nope

[rapid geode]

not true at all. tons of oversight, and remember they dont just tell teslas in the usa.

[late fulcrum]

Apparently you and I define "tactile" differently. For me, tactile can be run entirely by feel and has built-in mechanical feedback.

[rapid geode]

yes

so touch screen bad

?

[late fulcrum]

Yes, touch screens are the opposite of tactile.

[rapid geode]

ah, yeah, sorry. what i meant was that tactile performance of a touch screen is bad

[late fulcrum]

Ah, that I agree with!

There's a reason I keep buying phones like this

[rapid geode]

ha i didnt know they still amde any of those

[whole jacinth]

haptics can help, but they still don't compare to mechanical buttons

[rapid geode]

they can indicate a press, but they cant guide your hand really for placement on the screen

[glad ruin]

There is oversight in the US, but a lot of it is bureaucracy. "Fill out these forms to certify that you tested the thing". There doesn't seem to be much in the way of independent testing.

[rapid geode]

ah

Even though Apple straight up said they wouldn't support a physical keyboard, there's this iPhone case that adds one: https://hypebeast.com/2024/1/clicks-technology-blackberry-keyboard-iphone-ces-release-info

[fast ferry]

yeah, I saw that; looks like they did a really nice job, but the iPhones are already of the big & tall persuasion...

[late fulcrum]

Quite true. If they offered one for a Motorola Edge, I'd be intrigued.

[glad ruin]

I'll just wait until someone builds one with Cherry MX Green switches.

[fast ferry]

4.7" landscape slider with flagship-level CPU/mem/OS is my holy grail, but we've weirdly decided on giant phones and even gianter tablets. whatever happened to miniaturization?

[dusty citrus]

There is not either in the eu. Bigger companies do certify themselves, smaller ones need to pay. The mole of useless paper/burocracy is absurd.
Like we have eu/stare bounds (they give money to fund projects), but the amount of paperwork makes it tangible only to few companies, failing from starters promises of better stuff

[fast ferry]

I didn't hate a 5.4" screen, but it was a touch oversized and portrait sliders are a challenge.

[rapid geode]

phones are too big now. they are basically tablets. i like my old little samsung alpha

[late fulcrum]

I liked my Sidekick 3

[fast ferry]

and weirdly, you can't get a high-end, or even mid-end, 7" tablet anymore. they're nearly all 10"+

[rapid geode]

i have a galaxy uh.. e? 7". about 5 years old. maybe 6

cheapest with an ips screen at the time.

[glad ruin]

I'm pretty sure those were being sold at a loss initially. Amazon in particular tied the fire tablets to prime.

[rapid geode]

yeah i cant imagine there was profit on the $50 kindle tablets

[glad ruin]

I'm sure there was, in prime subscriptions and app store/in-app purchases.

[rapid geode]

yes, thats what i mean. not directly from the device, but as a package

like original x boxes i think were sold at a loss

or just milk in the grocery store

ha

(sell milk at a loss in hopes it makes people go to the store and buy cereal at 300% markup)

[glad ruin]

Well, I know that they deliberately put it clear at the back of the store to force you to go through everything to get to it.

And a lot of stores move things around periodically for the same reason.

Checkout counters are also intentionally inefficient and often understaffed.

[rapid geode]

milk has been the same price here for like 30 years

partially gov fixed, and partly cause they sell at a loss.

when you deviate to special milks (filtered, etc) the price goes WAY up

cause its not subsidised the same

[fast ferry]

@glad ruin nah, I was thinking the good 7" from like Dell or Lenovo. I have a couple Fire tablets somewhere, wouldn't recommend them for non-hackers.

[rapid geode]

i had a google tablet. i think it was really an rebranded asus

[latent gazelle]

Some Adafruit modules are STEMMA QT, and some are available ONLY as STEMMA.

Is there a way to mix those interconnects on a bus? Can I run 2 busses, one per cable type, from a single ESP32, with 6 spare GPIO pins?

If not, my feedback to the company is that many of these should be available in BOTH configurations. In particular, the module that measures amps is one that’s not required to be tiny, as I expect it’s only useful for debugging, not for a final project. The gamepad is another module that’s huge, prob’ly going to be packed into a larger container and could support a larger STEMMA plug.

[fair summit]

They are electrically the same. Some older products were developed before STEMMA/QT was adopted. Is this useful?

https://www.adafruit.com/product/4424

In particular, the module that measures amps is one that’s not required to be tiny
The gamepad is another module that’s huge

could you give stock numbers for these? I can guess, but knowing is better

[latent gazelle]

OK, starting to get it.

So I have to think about male vs female sockets, 3v vs 5v, 2mm vs 1mm sockets, and 3-pin vs 4-pin. And extracting this info from the text descriptions (maybe use a standard table?)

Then there’s: adding up the amps each board takes, deducing the amps provided by the I2C host pins, and figuring out if the GPIO pins are being used for something else.

Seems like a LOT of work that could be automated by a new Adafruit tool.

The power monitor is /5832

[fair summit]

The power monitor measures external power. The STEMMA/QT connectors are just for the measurement I2C data

the external device under measurement is not powered by the STEMMA/QT connectors

in general STEMMA/QT is used mostly to talk to I2C devices which don't take a lot of power. They are not meant for heavy duty powering

[latent gazelle]

Ok, that’s helpful. I reread that /5832 description... I think that page needs to point to the tutorial for the replacement chip: Adafruit-ina219-current-sensor-breakout. I thought it was to debug STEMMA over-current situations, but it’s to measure non-I2C currents.

[fair summit]

right, that's the point of the external screw terminals

[fair summit]

I think a guide is in process

[latent gazelle]

Right. Some of these variants, curiously enough, have no external screw terminals but just Vin- and Vin+ soldering pads. Like the one in the tutorial, or /904. I think I get it now; you’ve been quite helpful.

If some I2C need 3V and others need 5V, should I run two I2C busses?

[patent hemlock]

you can use "boosters" so that you can technically mix and match, but I2C is very sensitive to impedance, so if you you get too many "things" and/or too long of a connection wire between stuff, it won't work very well

[latent gazelle]

So two busses, then, to keep them separate? I’m planning on 5 devices, plus 3 fans (attached via I2C speed controllers).

[patent hemlock]

as mentioned above, you can use two busses, or depending on the voltage and current needs of what you hang on there, one might be enough (e.g. i wouldn't try to run any motors directly over I2C, but rather use a driver board like the motor hat for pi's)

personally i use i2c a lot because soldering isn't in my skillset

[latent gazelle]

I’ll try it both ways. One bus is better, but more expensive.

I just soldered some headers. Took an hour, and I melted only 1 extension cord. [don’t use a space heater on your soldering iron circuit.] It’s obviously not a strength of mine either.

[rare gulch]

Has anyone received Adabox 21 yet?

[fair summit]

Some chips are quite sensitive to overvoltage on I/O pins. For instance, SAMD51 can lock up. So use level-shifters as needed.

What's a good way to clean mixed oils off of a concrete surface? I was cleaning out my garage and left an old roommates cardboard box of mixed Automotive stuff in what I thought was a sheltered spot, but then it rained very heavily, see atmospheric River, and now there is a Sheen of oil on the path to my front door. Is this a situation where I use all my practice scrubbing penguins with Dawn to solve this problem?

[tardy badger]

Simply Green was what my dad usually used

I’m not a huge fan of it because it’s just not super environmentally friendly. But it works

[lusty fossil]

I don't have any plans nearby, but I assume the damage is done and I can just sort of learn my lesson and be careful in the future? There is an area where I might plant plants at some point nearby, should I just flood it with water

Plants sorry not plans

Yeah I would prefer something that's not really a horrific to the environment, because I have neighbors

[late fulcrum]

Kitty litter will absorb most of it

[lusty fossil]

Which kind of kitty litter? And how would it be applied, with water?

[late fulcrum]

The ordinary clay granules kind. No, water is immiscible with oil, just spread it on the concrete and it will absorb the oils from it.

[whole jacinth]

there are also spill cleanup granules you can get from hardware stores. they might be better than cat litter for oily stuff

[ebon dew]

There are industrial sized bottles of citrus cleaners that are environmentally friendly.

When I worked on my car often I preferred Fast Orange. You can get it in a 1 gallon pump. Just remove the pump and pour it all over the concrete. Get a big shop brush and scrub it in then hose it off. Anything with oil or chemicals it will clean nicely. https://www.amazon.com/Permatex-25219-Orange-Pumice-Cleaner/dp/B000HBNTX2

You could have your arms covered with old engine gunk and that stuff will clean it right up. Don't underestimate the power of concentrated citrus.

[rapid geode]

orange pummice is great, but its not citrus based, its only citrus smelling. The primary reason it works so well on your hands is the abrasive pummice.

General visual concept for my planned “cosplay-controller glove”

Basically an e-textile covering a cut-down workout glove. Gonna remove some chain links to make an electronics case, and print the hexagons black (maybe the links a dark red?)

Electronics are just

• BT/BLE stm32
• Battery manager backpack
• 3.7v 400mah battery
• gonna stuff some JST connectors in the case and wire them up to buttons on the sides of my fingers (those’ll stay put with tiny compression sleves)

Overall should have a kinda cyberpunky look? Maybe?

[burnt tendon]

oOooooOOh that looks really neat

[burnt tendon]

I've long wanted to do some structured things with the NASA hexagon chainmail. I did do some stuff with my own hexagon system that uses TPU because hexagons are the bestagons.

[hexed talon]

For the pro micro, is jumpers best to use there? Or can it be recommended to solder wires directly onto the pin holes? Or what would be recommended there?

[late fulcrum]

It depends on your use case. If you want to plug it into a bread board, Flip Pins or machined pins are useful. If you want to switch things around male or female headers work. If you would to build it into something, you can solder wires directly onto the pads.

[ebon dew]

From left to right. Female header, male header, stacking header. Modularity is a nice thing to have when prototyping. I wouldn't recommend hardwiring to pin holes unless you're certain it's going to be permanent.

Although unwieldy to store in a box or bin the stacking header offers the most versatility for connecting dupont wires from the top or bottom, or stacking add-on boards like featherwings together.

[late fulcrum]

Another advantage of the stacking headers is they have thinner pins than the square-pin headers, so aren't as hard on solderless breadboards when plugged into them

[whole jacinth]

i’ve found that the thin pins on stacking headers sometimes don’t make firm contact with female headers that expect square pins

[ebon dew]

Another disadvantage due to the longer thinner legs if you press down too hard you can pancake the pins outward. I've done it. You can straighten them out but the legs will never be the same again. One way to make them a bit more rigid is actually to use snips and cut them as short as normal male pin headers. I lay masking tape across the pins to make sure I'm cutting them all in a straight line.

Now this is a halftime show I’d watch.

Fair enough. Personally I’m at the end of my sanity when it comes to how many legit people out there think its all a conspiracy so I definitely came in hot

I never found it particularly interesting. Plus I spend the entire year avoiding ads, so I'm not about to watch a game that I find boring just to watch ads that I find obnoxious and inherently deceptive.

[tardy badger]

There was a time when it was cool and advertisements were funny

[late fulcrum]

Sometimes I'll watch the ads for that event, because for once the advertisers actually try to be engaging.

But ads in general just irritate me. There are a bunch things I'll never buy because of their ads.

[glad ruin]

Yeah but there's no reason to watch them during the game, since YouTube highlights them shortly after.

[late fulcrum]

For a long time, I wondered how the ad biz even stays afloat, since most of the money is wasted. I later realized that there are people out there who are not like me and will buy what the ads tell them to. That explained SO MUCH. I think that relevation hit in grade school.

TiVo has an option where their usual "skip ads" is replaced with "ads only" too.

These days, I just let my friends curate the ads for me and just watch the ones I might be amused by. I realized recently that I'm so out of touch that there's a film coming out that's effectively made for me and I didn't even know about it!

[glad ruin]

What film?

[late fulcrum]

Lisa Frankenstein. It's for those few of us that love both bright colors and cheerful imagery (if you know who Lisa Frank is, you know what I mean), and dark brooding horror tales. And I do like Cole Sprouse as an actor. And Diablo Cody as a writer.

[opaque atlas]

morning folks. Anyone here familiar with RFiD antenna/circuit design? I need to make a MFRC522 RFiD reader board that is smaller than 24x24mm. I'm pretty well versed in Analog and using micro's etc, but RF seems to be a bit of a black magic.

[tardy badger]

Spoiler alert, it is black magic 🫣

So in general, you can find some design specs online that you can follow. The hardest part will be tuning your matching network

[opaque atlas]

i had the feeling that was the case

[tardy badger]

For that, depending on the RFID frequency, you can do those measurements with a NanoVNA

You’ll want to get some SMA to pin probes

Or if you put a U.FL connector, an SMA to U.FL connector

[urban arrow]

SBowl I'm a fan, and mostly watched it, BUT when I noticed Penn & Teller on another channel, I kept switching to watch magic 😀

[late fulcrum]

You can add turns to the coil to get it to resonate, but your field size from such a small coil will be small. However, I've seen it done (some glucose monitors are about that size and use NFC)

[tardy badger]

I figure you just need a long enough wire in your coil

[glad ruin]

Even then I recommend avoiding u.FL unless you absolutely need it. Those connectors have a cycle life below 50.

[late fulcrum]

TI's RF430 line includes a bunch of useful design information https://www.ti.com/product/RF430FRL152H

[tardy badger]

RF430 are pretty nice

[tardy badger]

I figure if you just keep it attached only for doing the network matching tune

Though RFID network matching isn’t as critical as like.. Bluetooth or WiFi

[glad ruin]

I mean... if you can prevent it from moving around, sure.

[late fulcrum]

It's not the length of the wire as much as the inductance, and it's not the inductance as much as it is the resonance. Basically a lower inductance antenna will need a larger resonating capacitor to match the same frequency

[tardy badger]

Antenna theory is fun

[opaque atlas]

the size of the cap doesn't bother me much to be honest. I have Z space under the board

[tardy badger]

Mostly talking about size in terms of capacitance rather than physical size

[opaque atlas]

roger that.

It's the 3 stages that's kinda bothering me - the EMC filter, Impedance Matching and the Antenna itself.

[tardy badger]

Personally, I’d use a premade antenna template, or even one you can connect to an FPC connector to make it easier. From there the EMC and impedance matching should be less stressful

[opaque atlas]

yeah - i'm considering that too. https://www.digikey.com/en/products/detail/taoglas-limited/FXR-1515-A/18153983

but that only solves 1 of 3 issues. I need to make the EMC filter AND the Impedance Matching filter.

[tranquil swallow]

is there a reason to get rosin flux if i get no clean up flux

[opaque atlas]

@tranquil swallow looks nice. doesn't get dust stuck to it. for a one off project that you're keeping for yourself, I'd leave it as is. If you're making money from the product and building many, maybe a different story.

@tardy badger The off the shelf antenna has these characteristics. that may be enough to get me going:

[tardy badger]

Those will help a lot. One thing to keep in mind is the PCB stack up, trace width, and whatnot will have an affect on the matching network. But having the antenna characteristics are helpful for having a starting range

[opaque atlas]

i ultimately need to be able to read an 13MHz NFC Tag through 5mm of foam. This doesn't need to be a perfect design, but it does need to work! 😉

I'm perma banned from ebay for "selling fakes"

[rapid geode]

why were you selling fakes/

[late fulcrum]

I had one friend who said they "needed a laptop". I said I could just pull one off the pile. No, it had to be a particular laptop. Seemed like an odd choice, but they said "it was required for school". Okay, found some suppliers that had refurbs in stock for a few hundred dollars. No, it had to be this particular $1200 one and could I pay for it? Um, nope. I later found out they'd seen it on eBay, got excited, clicked on "buy", then realized they didn't have a spare $1200 and hoped I'd just give it to them. "For school".

[rapid geode]

doh

"people"

[dusty citrus]

I wasn't, it's just that some other sellers exploit the vero system to ban the competition out
What's even worse is that ebay doesn't even check

[rapid geode]

ah yeah. ebay is lazy sometimes

[late fulcrum]

Yeah, if you want fakes, you don't go to eBay, you go to amazon.

[rapid geode]

ha

amazon is lazy the other direction for sure

aliexpress i only trust after somoene else i know has bought form them

[dusty citrus]

Amazon is even worse, if something sells, they clone your product, then put you out either by claiming that your "original" product is a fake, or by boosting their own product over yours be ads or pricing

[late fulcrum]

Not only lazy, but they'll switch up the merchandise en route so you could buy a genuine item from a legitimate seller, who ships the right thing, and amazon will deliver you a fake from some other seller because it was in a closer warehouse. That's their "equivalent merchandise" policy.

So even if you see someone saying "oh, if you buy it from this particular seller, you'll get the right one", that's not something you can rely on.

[rapid geode]

ive hear this. in canada this seems to be less of an issue as most items come "from amazon" and not amrketplace sellers.

[late fulcrum]

Wow, I wouldn't trust that either

[rapid geode]

when i read reviews i can see that clearly in the us the item is from a marketplace seller that might be sketchy

[dusty citrus]

They don't want to deal with possible lawsuits, so what they do, after banning, they get your id in pesky way and delete from their sites everything about you, so there's no data left
Positive Feedbacks are pointless, it's more effective the word of a random that claims to have the copyright over something
It shouldn't work like that, but you know lawsuits are expensive, and ebay is basically an oligopoly

[rapid geode]

ive had no amazon issues except that time i bought an induction cooktop from spain and the forst one was smashed to bits

[late fulcrum]

After having strings of horrible issues, doing some research, and hearing what they do to their customers, employees, and vendors, I just don't do business with amazon any more.

[rapid geode]

i have a pretty narrow range of items i buy from them though

[dusty citrus]

It's pretty great for shippings and warranties though, also pretty great when they wrongly list their items, there's an high chance that they do ship anyway

[rapid geode]

i mostly buy from the same handful of ebay sellers. cnc parts usually. couple bike things. i sell cnc parts and bike parts too with good results usually

right now i had a guitar pedal up there and the guy bid, put in offer. i accepted, they didnt pay (yet)

if it was $30 id just wait an not care. but this is expensive and other people also want it

[dusty citrus]

For anything else it's just AliExpress drop shipped like of stuff
Too expensive for crap

[rapid geode]

aliexpress i get cnc tools usually. not much else.

cause thats one of the things i cant easily buy here except for really expensive ones, and i need a reliable supplier

there is a guy on ebay i use for tools too, but he has a limited selection of very niche tools.

[dusty citrus]

Btw I was looking to get one, a printnc of about 350mm working area, seems to cost around 1k...
I just want something somewhat "domestic" not a bulldozer

[rapid geode]

im selling the frame of my little one on ebay.

but i wont sed it to italy. it would cost $1000 (not even a joke)

i sold a spindle to honda in japan and it cost $1400 to ship. ha

italian spindle. so i guess them trying to get it direct from italy was worse. maybe bad tarrifs

[dusty citrus]

One time you didn't pay vat over cn stuff
Now you need to pay even vat, if the platform itself doesn't collect it, then there are customs yuks
What's even worse you can't find anything locally

[rapid geode]

i bought some bike wheels from germany and they came damaged. they sent me new ones and said keep the old ones. it does pay to use good stores sometimes.

[dusty citrus]

In the end the only good thing about that printer were the display and the motors. As the main board has the rom that behaves weirdly: when rewritten it holds the new program till it's powered on, then it forgets and keeps the old program. Somehow it became a weird ram

why did nichicon discontinue their fine gold electrolytic caps, it's getting hard to find a reliable supply of aesthetically pleasing capacitors

[late fulcrum]

The UFG and UKZ series? It could be because they had unetched electrodes, and they no longer care to make that style. They're still making some of the UKW line.

It looks like they're discontinuing all the 5x11 and 6.3x11 sizes. Those would be the low value ones, which you can replace with film capacitors (available in lots of attractive styles)

[opaque atlas]

Hello folks, I had such and inspiring chat with y'all yesterday whilst I was conducting a project thought experiment, my adhd riddled brain decided to embark on a new exciting adventure into design.

If I wanted to use a flickering LED as a reference pattern for a larger non-flickering LED, how would I (or you?) go about it?

First thought that comes to mind, use it inline with a common emitter NPN BJT transistor setup. As the current flow through the small led changes into the base, then the transistor should amplify it in the collector?

[glad ruin]

An emitter-follower could probably do it, but keep in mind that there will be a fairly large DC offset, so you may not be able to put that LED directly in series.

[opaque atlas]

blast. I'm just trying to "copy the current, but make it bigger".

there's already a nice random noise generator in the reference LED... I guess I could always use an opamp across a series resistor to the reference diode

that'd amplify the voltage seen across the reference resistor.

odds are it's a PWM output.

[glad ruin]

You'd have to try probing it. Regardless of how it operates, the flickering effect will most likely be visible in the current draw.

[opaque atlas]

it's definately a pwm (just benched it). I'll need a low VGS NFET to make sure it switches on

As LED's are 1.8, but many low cost Mosfets are 2.1V etc.

[glad ruin]

Or just use a BJT.

[opaque atlas]

i considered that, but then I'll always have current leaking through the base.

(I'm essentially making a potential divider with the led and resistor, then tapping off the center point to the high impedance gate of a mosfet)

[glad ruin]

I would implement it more like a trandimpedance amplifier.

So, very low impedance input in series with the flickering LED, then a voltage output that controls the larger LED.

[opaque atlas]

what I benched earlier... and it works... ok 😉

If I could rip out the little logic die in the mini LED, I would 😉

[glad ruin]

Since the small LED is just using PWM, you could also set up a comparator (with a little bit of hysteresis). A lot of comparators have an open-drain output that is easily capable of driving an LED.

[opaque atlas]

the bigled can source about 100mA (or 300 if I'm feeling naughty). A single MOSFET is way cheaper than a comparator.
I was always taught "a good engineer does for $0.05, what others do for $5"

[glad ruin]

Depends on what you have to compromise.

In this case, a comparator would likely be overkill though.

[patent hemlock]

2 sheds? dude...

[rapid geode]

need mo room

he

im allowed 3 actually

[dusty citrus]

I mean in most cases in the end you're "googling" for the right results, in other words picking the image that you.
like most out of the outputs

As for me I don't really care since art was never profitable for me & I'm not active on socials/online anyway eheh

[rapid geode]

the rules are under 15m2 per building, and you cant cover more than 10% of the lot

so im allowed 390 sft of shed. (right one is 110, left one is 157)

[patent hemlock]

my "workshop" is 50cm x 100cm x 75cm 😸

[rapid geode]

ha

but for real, the second shed on the left is a test for my tiny house project

[patent hemlock]

just two opinions/suggestions -- stay away from induction cooktops (although they're great for space, the specific cookware is non-cheap); if the entire bathroom is a "wet room" you have a storage problem (i personally wouldn't want my toothbrush and deodorant in the shower)

i watch a lot of remodeling shows ... 😀

[rapid geode]

1: induction is the best, the cookware now is very cheap. i bought a nice sauce pan for $19 at ikea

[patent hemlock]

ah!

[rapid geode]

2: we have a curtain mid way. just not visible

[patent hemlock]

👍

i do like that sink

[rapid geode]

can see the rail there

[rapid geode]

the sink is one i have spare here. haha. $120 at home depot. 😛

trying to keep this house "relatively" cheap.

about 100k cdn plus site prep and land

seems fairly on track so far.

main issues is transport. connecting modules together and height restrictions. so i want to build a shed to explore some building techniques

like a mass timber floor and roof

[late fulcrum]

Bathrooms in Iceland are basically wet rooms. It takes a little getting used to, as does the scent of the hot water (sulfurous geothermal hot water, the upside is that you never run out)

[rapid geode]

mass timber wont make anything thinner, but it will allow me to pop the roof one as a single unit on site

[rapid geode]

yeah, wet rooms are not very common here

but there are lots of advantages when you need it to be very small

[wraith notch]

Honestly a good tradeoff

[rapid geode]

i wish i had geothermal. oour water is just barely above 0c here

we had a deep lake pilot project. where we pulled water from the bottom of the lake where it is compressed at a stable 4c. then it goes through a heat exchanger to run AC and finally gets delivered to buildings (commercial) at 13c

[late fulcrum]

We're thinking of replacing our old oil burner with geothermal heating/cooling

[rapid geode]

im on rock, so cant really do anything here

[jagged citrus]

nah ah ah

it had the s word

let me censor it

there we go

someone just sent that on another discord

[rapid geode]

ha

people have already been starting to quesion video evidence in court claiming they cant prove it is real

(usually you can)

[jagged citrus]

Just imagine

All of the ai generated videos, with ai generated music and ai generated voices

So much slop

s l o p

Also, a couple of months ago i stated my opinion on the pi zero two, time has passed and ive now changed my opinion, since:
1- its price has been lowered, and can now be found for less than ~$30
2- due to its age the banana pi zero has lost a lot of suport and its harder to get running, which most likely wont happen with the pi zero 2

Meaning that in my opinion, its good!

But with the popularization of the Allwinner H618 in SBC's and the rise of RISC-V, with time we'll see how it goes

So uh yeah

Ill eat my own words

also im actually surprised at the amount of new RISC-V things that have popped up

[sudden bolt]

hihi general

[tardy badger]

Got my TFT BFF working

[dusty citrus]

May I ask how are you with a mac ? I've been tempted to get one due to a battery that does actually last
But programs compatibility and limited memory throw me off
And then there are docks that never work no matter how much you spend cause it's the same rebranded oem

[tardy badger]

I’ve not had a negative experience with a Mac

Battery life has been good even 6 years on

[haughty solstice]

So a while back I tried to use a micro SD card with the TMRpcm library and an Arduino Uno. Something broke, and it kind of bricked the SD card... I think? I plug it into my machine, and it says it's write protected, even though it's not

Anyone have any ideas for fixes? Diskpart did not fix it

[rapid geode]

another 2 years and it might finished opening that file...

😛

[tardy badger]

It only takes 5 minutes, thank you very much

💀

To be fair, it’s struggling with the basics these days. Probably due for a clean Mac OS install

[dusty citrus]

Ah I thought it was one of those "newer" m processors

[tardy badger]

Nah, 8th gen intel i5

[jagged citrus]

Check dis out

A pcl82

Vacuum tube

[late fulcrum]

Nice!

With socket, too. Nice little triode-pentode

[jagged citrus]

The guy that sold it to me was so surprised that someone my age was interested in tubes he decided to give me the socket for free

[late fulcrum]

Bonus!

[jagged citrus]

It cost 10 bucks

😎

Online its like 20

[late fulcrum]

I've been known to tack wires to tube sockets and build stuff on solderless breadboards

[jagged citrus]

Thats neat!

But for the amplifier im planning in making ill design my own board

Also this little guy just arrived

[jagged citrus]

oh yeah to elaborate on this im going for the low voltage 40v design i found on hackaday

the same one that had the horrid comments that got me a warning in here

[wraith notch]

the machine-god salutes your efforts

[jagged citrus]

i loved the part when he said im the warhammer 40k and started warhammering all around the place

true cinema

[jagged citrus]

yo

does anyone have a good resource on developing an atsamd21 based dev board

seems a lot harder to figure out than the esp's

[tardy badger]

Use the Adafruit schematics

Feather M0 would be a good starting place

[jagged citrus]

where can i steal
i mean find them?

ive looked but havent found anything

[tardy badger]

Adafruit learn guide

[jagged citrus]

oh ok

thanks

[tardy badger]

https://learn.adafruit.com/adafruit-feather-m0-express-designed-for-circuit-python-circuitpython/downloads

[jagged citrus]

yeah i was thinking of looking at some adafruits designs like the trinkeys

which some are based around the atsamd21e18

[tardy badger]

The E18/G18 are nearly identical with some minor differences

[jagged citrus]

i believe the G18 has more pins

the reason why i was interested in the E18 is because it seems to also have an internal crystal

none of the trinkeys features one

[jagged citrus]

*samd21 ones

also i have to say, the trinkeys are genius

[night crescent]

Desk of Ladyada - HV UPDI and I2C WDT https://youtu.be/sfbGpmJx3Jw

Focusing on finalizing designs, including the HV UPDI programmer with a 12V booster for high voltage pulses. The non-HV version is already in stock. Revisiting the S-35710 breakout, intended as a low-power sleep chip, but found it works better as a WDT chip. Additionally, explored replacing the classic LM7805 regulator, a staple for electrical engineers, with a 1A or higher current alternative.

[tardy badger]

It’s more than just “it has more pins.” There’s more functionality available on more pins, and an extra i2c and spi peripheral

[jagged citrus]

Oooohhh

Interesting

[median viper]

Hello Adafruiters. Hows it going I have so much to catch up upon.

I can't keep up with video

IT's too many hours of video to keep up with I have alerts on my phone for adafruit but I am just having difficulty keeping up

I wish that @night crescent would use voice transcription software to make more indexible stuff on the web.

[median viper]

it's just information overload

I created a fire detection ML algorithm that works really well for Terrestrial Cameras with a low electricity footprint, but I will have to use something besides raspberry pi, because the electronics industry cannot keep up with the demand, I haven't found a suitable electronics platform that can help people do fire watching.

NVIDIA jetson seems only thing to use

[tardy badger]

Hi yes. I am looking for motivation. If anyone has any to spare, please send by air drop to Utah. Kthnx

[tardy badger]

Yep, Robinhood

[ebon dew]

I'm full of motivation this week. Can spare some as long as it's not for an FPGA project. My motivation is incompatible with FPGA's.

[tardy badger]

I just need motivation for general work lol

[tranquil juniper]

I am very excited to get my adabox this week. I was not aware it was coming until I got the shipping notice lol.

I am sure it is somewhere that I'm not looking, but is there a way to unbrick a Hallowing M4? The power led lights up, but nothing else. Anyone have a link they can point me at?

[median viper]

$$$$ that's brutal

[late fulcrum]

It would be if it's something expensive like Kester 62/36/2 solder

$126 for a 1 pound spool...

[glad ruin]

That is MAIYUM.

please do not put YUM in your brand name if you are selling solder

[burnt tendon]

It could lead to bad things.

I thought of a funny way to introduce differential equations really lightly. Those times when you walk toward someone in a crowd who has the same “avoidance rhythm” as you do so you go another way, but they thought of the same thing so you go the opposite way, but they react at a similar speed to you so it repeats until you have to stop since you’re too close

[royal plume]

I'll join the live event next time and ask about the .status report on the BNO085. Brian Siepert could probably answer quite well. He's done great work with the BNO085 libraries

[late fulcrum]

You can make the code available in any of the popular code repositories (gitlab, etc.). You might also put a brief description and link in a place like #show-and-tell or one of the more specific channels if it aligns better there.

[tardy badger]

Kind of interesting how last week the FBI director mentioned that mass cyberattacks on US infrastructure was likely to over the coming months and we now have a massive nationwide outage of AT&T, as well as some regional outages of other cell service providers.

Hopefully it doesn’t spread to LAN connections

Hopefully they can get services back up. I saw some places in Pennsylvania were experiencing outages with their 911 service.

I also hope it was just someone deploying a bad configuration and not an actual cyber attack

[whole jacinth]

huh, maybe that’s why my (AT&T) cell service dropped to “SOS only” for a while this morning

[tranquil swallow]

how'd those russian hackers manage to down every iphone

[tardy badger]

Good news is experts don’t believe it’s a cyberattack

Sounds like someone pushed a bad config

[tardy badger]

I visited the r/prepper subreddit and the arguments over “this is normal” and “it was a solar flare/cyberattack/etc..” are very entertaining

[brittle linden]

Make everyday Y2K!

[tardy badger]

Quick, everyone turn off your computers

-real things done on Y2K

[ebon dew]

that subreddit is probably entertaining on any given day. we do need to stay away from conspiracy theories here though. pretty sure is part of the code of conduct.

[tardy badger]

It is

The outage is real though, the cause? Unknown

Very likely someone accidentally pushed a bad global config

[ebon dew]

Did they rename AT&T to AT&X yet?

[tardy badger]

Lol

Just a summary for those outside the US

Just another day in the neighborhood

https://tenor.com/view/sweats-gif-25346666

[ebon dew]

Can't report an outage if you have no service.

[tardy badger]

The intern who messed up

[ebon dew]

right lol

there's probably someone at AT&T who is like "I'm so fired right now".

[tardy badger]

Bob: walks out of the building with all their things
Janet: “why are you leaving?”
Bob: “I’m probably fired”

[ebon dew]

So tell me about your skills. "Well I enjoy being proactive about issues for example in my last job I fired myself".

[tardy badger]

Though, I sometimes envision a world of empowered workers taking down infrastructure their company manages when news of mass layoffs are coming.

And there’s like 0.01% brain that was like “AT&T is about to lay people off and the outage is a distraction”

[late fulcrum]

Heh, I got caught in the AT&T/DirecTV layoff several years back, when they shed about 10k people.

[tardy badger]

In other news, I leaned back in my chair and heard a support bar that secures the left arm snap 🥲

[ebon dew]

You can't be malicious like that though you'd invite a personal lawsuit from a huge corporation, the damages of which you could never possibly repay. There have been plenty of examples of disgruntled IT admins taking down their networks and then getting sued for millions. There's a difference between incompetence and malicious intent.

[tardy badger]

Oh absolutely

[ebon dew]

Ah yes the office chair snap of death. Been there. :/

After breaking my 2nd chair from leaning back, I stopped leaning back.

[tardy badger]

I’m terrified to lean back too far now lol

This chair is like 5 years old

Amazon Basics low back office chair. It has served me well

Pretty surprised an Amazon chair would last as long as this has

[ebon dew]

Yep that's about how long it takes for the back support to flex over time until it snaps in some of them. Yes, it's the cookie cutter office chair.

I took one apart once and found the seat cushion base was made with cardboard and Indian newspaper clippings. Was going to redo the cushion, wasn't worth the effort.

[tardy badger]

Makes sense. The back cushion is just hollow lol

It’s been one of my more comfortable office chairs though. Which has been a surprise as well

[ebon dew]

Kind of like macrome or whatever it's called. The newspaper clippings were glued in layers to the cardboard.

[tardy badger]

My wife has a really heavy ikea one with the mesh backing. Not all that comfortable

[late fulcrum]

I tried the mesh chair from Staples. It was comfortable for a while, but then the mesh loosened and it's kind of unpleasant to set in. I considered buying a used Herman Miller Aeron, but even used, they're kind of pricy and you have no way of knowing if it has tobacco smoke odor. Currently auditioning one of the FlexiSpot chairs

[tardy badger]

I was thinking about getting a gaming style chair

[ebon dew]

I have one, they're actually worse for ergonomics than a regular office chair. The Herman Miller style's are the most comfy but pricey.

Gaming chairs are made with fake pleather like you find on headphones that eventually peels off and you have little black bits stuck to you everywhere.

[tardy badger]

I’d love a secret lab chair but that’s a bit rich for my blood

I can’t justify $600 for a chair

I could barely justify $12 for a Pac-Man desk mat

[ebon dew]

right. I can make my own for that much.

[tardy badger]

I have a cheap Walmart special Logitech keyboard and mouse lol

I used 24” Lenovo monitors my wife got for a job but they didn’t want back

[ebon dew]

i have a 3d printer. maybe i could build one in sections a little at a time. 😅

[tardy badger]

My gaming headset is a $35 EKSA headset lol

[late fulcrum]

I was looking at Secret Lab, but realized a gaming chair probably wasn't what I wanted, hence the FlexiSpot (which is less expensive as well)

[tardy badger]

I’ll have to take a look at Flexispot

[late fulcrum]

My main headset is a Plantronics, it's excellent but fairly expensive. I use it with both my phone and computer, courtesy of a ZoomSwitch (the Plantronics MDA220 wasn't available at the time I bought it)

[tardy badger]

I’m honestly surprised my headset sounds as good as it does for $35

[late fulcrum]

Unfortunately Teams keeps dropping the connection to the ZoomSwitch in the middle of meetings, so I use a $10 Logitech headset for Teams.

[tardy badger]

Which flexispot chair did you get?

They currently have like a 50% off sale

I see their C6 chair is on sale for $129

[late fulcrum]

I got the FlexiSpot C7G-Mesh. I used both the sale and a discount code I got from a YT video to get an attractive price.

[tardy badger]

How do you like it so far?

[late fulcrum]

It's way nicer than the other mesh chair. My main beefs so far are the adjustable armrests are too adjustable, if I try to push on it to reposition myself, it slides instead of giving me something push against. Also, the chair back is taller than my previous office chair (a really comfortable dining chair I got as a gift from a family that was moving and didn't have room for it any more), making it harder to do seated weightlifting.

Current FlexiSpot discount code is F10uN4SX for 10% off anything in the store.

[burnt tendon]

I always get punchy about the Y2K thing because my mom spent years of her career fixing Y2K stuff so when it came, nothing went wrong.

Adjustable armrests are so annoying to me that I special-ordered a chair without armrests.

Probably my personal geometry.

[late fulcrum]

That's a thought, I could just remove them.

[ebon dew]

I require arm rests in my chair. I won't buy a chair without them. To each their own.

[fair summit]

Armrests aggravate my cubital tunnel syndrome.

I just didn't install them on my (unassembled) office chair

[tardy badger]

I tend to lean into my arm rests. I also generally want a chair that rocks a little

I’m not sure if I want to spend $309 on an office chair though

[tranquil swallow]

isnt standing the new trend, we don't need chairs anymore

[tardy badger]

When working, I’ve seen them recommend 30-40% standing, 60-70% sitting

[late fulcrum]

I have foot issues, standing simply isn't an option. I can walk ten miles, no problem, but standing ten minutes is painful.

[patent hemlock]

i have a partially collapsed disk, so with my former employer's special discount plus a wee bit of insurance money, i got a $1000 chair for $600 (so far it's lasted 6 years of heavy use)

[median viper]

@late fulcrum hey you around? do you know the lead times for the raspberry pi 4,5 and it's market volume to stock?

Because I think that the shortage of Raspberry Pi makes it not worth a device to build any kind of IoT sensor network from it's just too popular.

Nvidia Jetson Nano costs 4x as much and it' not much better stocked

[tardy badger]

RPi is pretty in stock right now

https://rpilocator.com/?instock&cat=PI5

That’s all the places you can order a Pi 5

https://rpilocator.com/?instock&cat=PI4

And that’s Pi 4

Raspberry Pi are very obtainable right now

I even saw CM3 instock

[median viper]

Thanks, @tardy badger

[dusty citrus]

I'm starting to think that people are nuts.
Some random expect me to travel for 8h to make an interview with him

[median viper]

yeah they nuts I be interviewing all over the place, it's just that I am working on my last semester of master's degree

so I am not looking that hard just responding to linkedin recruiters and such

I get like 3-4 recruiters a week calling me

[late fulcrum]

I'm around, but don't know anything about the lead times for Pi boards. I don't normally think of them as IoT boards (other than the old $5 Pi Zero), same for Jetson.

[median viper]

Well computer vision boards, sorry for not being explicit. The machines have to be able to run tensorflow lite at least

[late fulcrum]

Ah, that's a heavier task. There are a few dedicated boards that do some tasks, but if you're building custom models, it's a little trickier

[median viper]

yeah and the power consumption greatly varies as per the alglorithm, such as a custom CNN vs. EfficientNet or MobileNet

those are the top algorithms

it spikes from 80W to 180W

or 50W over baseline

for the minimal

so I am trying to keep it lightweight

[dusty citrus]

It may not be what you were looking for, but have you considered into looking for tinyml? It runs everywhere although you need to pretrain it somewhere else first

[median viper]

I have it already pretrained, I am just looking for candidate deployment devices

[median viper]

it looks european

[deep heron]

Hi ya'll! I'd love to see how much you charge for workshops for companies. What's your hourly rate for things like this, workshops for companies?

More info and context: I'm talking to a Boston-based startup and they're doing clothes + electronic sensors, needing both design/drafting/assembling/sewing and electronics (soldering, programming) experience. I got both, no problem.

They're interested in flying me over in Boston for a weekend or week to build a prototype, and they'll pay for flight/food/ground transport/etc, and materials.

They want either:

1. an educational workshop where I teach them the basics of electronics, or
2. I go play with different materials alongside their engineer and work together to make a prototype.

I want to prepare them with different packages, but I need a good base hourly rate to be there. What do you suggest?

PS: I do have a PhD in computer science, taught in universities this stuff, experienced costume designer/prop-builder and I'm master-rank in craftsmanship, so I suppose I'm medium to high credentials on this. I'm also in Silicon Valley, so my rates here alone are probably higher than most.

[late fulcrum]

Generally $200-300/hour for this sort of consulting

[tardy badger]

I typically consult for between $75-$150/hr depending on the mix if not expected to provide anything physical

If I’m providing anything physical, closer to what madbodger said

[late fulcrum]

Slightly relatedly, I'm being asked to fly out to Lexington, KY for some consulting. One airline offered me Washington, DC -> Louisville, KY -> Chicago, IL -> Lexington, KY. Wat. It's quicker and cheaper to fly to Louisville and DRIVE to Lexington.

[median viper]

it's easier if you have an audience and charge reasonable prices for admittance to an event and the audience splits your bill. I mean you want to be charging the same thing as Taylor Swift for her concerts go ahead.

and then that was the shenanigans that happened with ticketmaster and stuff

[deep heron]

hey, i'm sure the client wants to save money, i'm sure you can get them to do that and charge them for gas/airport parking/flight

[deep heron]

thanks for the recommendation! that does sound about right! I feel more comfortable asking for that, thank ya!

[deep heron]

oh that's a great distinction. it is indeed physical, so that involves more. Then yes, i'll definitely follow your recomemndations, thank you!

[deep heron]

it does actually add up that way! with that rate! the audience is a small startup, only 3-4 people

[median viper]

Yeah the cost/value proposition of every product/service nowadays needs to be taken into account.

[jagged citrus]

that is not an ecl82

Wait what

they separated the tube into 3 parts.....

why??!???!?!

whats wrong with having this

also, im 99% sure the footprint is wrong

ill look up if someone has already made libraries

note that im actually using an PCL82, not an ECL82, however they have the exact same pinout and size

i also checked with this circuit i found

same pinouts, and same symbols

tubes are so wacky

[glad ruin]

If the component has multiple distinct units, breaking it into separate schematic symbols makes sense.

[late fulcrum]

They're often drawn that way on schematics, often with a partially circular envelope with a flat dashed section to indicate it's part of the same package.

Tubes are fun to play with, however

[jagged citrus]

Woah are those like electronic component blocks?

[late fulcrum]

Yup. Clear blocks with magnetic contacts on the side and schematic symbols on top. When you arrange them into a schematic, you've build that circuit! They're awesome.

[uncut trench]

Yeah, not that I'm looking for work any more, but in today's world, asking me to travel 8h for an interview is an instant fail on their part. You do an interview of that sort by Zoom. If you can't, I probably don't want to work for you.

[fast ferry]

hope you enjoy Lex! I used to be active in the tech scene there, great city with good people. super curious about the client, but definitely expect that's private info.

[fierce prawn]

[merry thunder]

Hello, I want start my career in electronics, can anyone help me to do it

And provide me guidance

[ebon dew]

If you're looking for a career (in anything) then typically the best avenue is through intense education in that area of study.

Until Youtube starts handing out degrees along with their platinum play buttons there is no self-taught person that will outperform someone with an educational degree during the interview process.

[merry thunder]

Yeah!..I agree with you and I have an electronic field in University but.. the study here is just! Useless

Like they teach only for placements and jobs

I am not after the placement or job

I just want to learn this stuff, this field

[ebon dew]

"Hello, I want start my career in electronics, can anyone help me to do it"....

[merry thunder]

Yeah!.. my career (my life)

[ebon dew]

Does this University have a guidance counselor at the facility? I would recommending scheduling some time to talk with them.

[merry thunder]

Moreover I have wasted my so much time on wondering what I have to do, I have also learned programing languages like , c , c++ , javascript, python. And I do web development.

But I am not interested in that so much

++am tired of my life, by thinking what I have to do!.

(pls ignore my grammar, English is not my native language)

[ebon dew]

Sounds like you're waiting for someone to tell you what to do, what to decide. That's part of being a self-determined individual. That decision is solely up to you.

[merry thunder]

They are useless (i am in 3rd tiers college)

I want to learn electronics, but due to this rat race , i thought.. I shall go in this IT stuff!

I am just confuse from where should I start

[ebon dew]

That's exactly what the job of a university guidance counselor is for. If you think they aren't doing a good job of helping you perhaps you should let them know that.

[merry thunder]

I don't want anything from University.. I am ready to learn myself just need a little guidance, i got in University bcos I thought i will learn something but, reality is different, moreover if I do something like this instead of helping me they will put more focus on me for studies.

The thing I don't even want to study

I am ready to do everything by myself.. just need little guidance from where to start

I have already wasted 8 years of my life

[pallid sundial]

any of you guys use ESP32 here?

[tardy badger]

Lots of people here use esp32, it’s usually better to ask the specific question you have rather than feeling out if someone knows the general topic. If you’re doing stuff with the esp32 in Arduino, there is #help-with-arduino for micropython/circuitpython you can head to #help-with-circuitpython and for general project help #help-with-projects

Additionally, if you’re designing an esp32 board and want help with the hardware design, #help-with-hw-design would be a great place to ask

[tardy badger]

What exactly about electronics are you wanting to learn? Are you trying to get into electronics design/manufacturing? Are you wanting to do that as a career?

[merry thunder]

I want to learn,
how Circuits are made! , how PPL decide where and which component is use! Like.. example how they made a radio circuit by joining some components how they know where to use which component.
I want to know how electricity work!. Bcos I don't even know this simple thing.. is 5v with lots of amp is dangerous or lots of volt with some little amps is dangerous.
How ppl calculate circuit!. Like I heard a new thing 2 port port network which I don't understanding, where it is used what is it!
I want to know how to make logics for circuit, like microcontroller how can I make my own micro controller.
I want to know if I made something... How to make driver for it.
How circuit board are design!
How to combine different ICs to make a something logical like a small 8bit computer.. and how big ones are made.
How ram is made with flip flops. There are different flipflops
How transistor are use to make different gates.. or can I make something new with it..
Lots of thing.. idk where to start

thanks

The Art of Electronics is a classic recommendation though some people can find it a bit abstract.

I think it covers topics in a fairly comprehensive way, or at least gives you an idea of what you can search for and find additional explanations. I like Khan Academy videos. They were pretty helpful when I got my bachelors in Computer Engineering

[merry thunder]

This one?

[tardy badger]

Yup! That’s the one

[merry thunder]

Ok..

[tardy badger]

Microelectronic Circuit Design by Richard C. Jaeger is also a great textbook

That’s the book I used in my electronics course work

And for circuit analysis, Basic Engineering Circuit Analysis by J. David Irwin

Most circuit analysis and design can be done with basic calculus and differential equations for RLC circuits.

Best of luck on your journey, we’re here to help along your journey 🤓

[merry thunder]

Yup, thankyou so much

[late fulcrum]

It's rare, but it does exist. I never did get a degree, but I've gotten tech job offers over people with degrees in the field more than once.

[late fulcrum]

I don't think it's a secret, I'll be consulting for Link-Belt

[patent hemlock]

i actually tried "un-retiring" but it seems the job market isn't open for geriatric software engineers 😏 -- good luck to everyone out there

[tardy badger]

It’s tough even for non-geriatric software engineers.

[patent hemlock]

exactly: y'all need it more than i do

[late fulcrum]

Weird, I still keep getting companies reaching out to hire me

[patent hemlock]

some of the "consulting" gigs were, quite frankly, insulting given my experience (keyword search and copy/pasta from lazy recruiters trying to make quota)

[tardy badger]

I get these as well. And for whatever reason I end up getting ghosted even though they reached out to me lol

Apparently my entrepreneurial ambitions scare hiring managers 🤷‍♂️

[burnt tendon]

I mean, I've got some heads open if you are good at Kubernetes and/or Prometheus.

But, yah, I dono, the thing that bugs me at the moment is that there's this set of people who write individualized emails for me, apparently unaware that the database they are using is out of date because they think I work at the prior job and they are trying to interest me in some random franchise business.

My presumption is that they people who are reaching out to me are the suckers, who were sold a false bill of goods about a can't-loose franchise business opportunity with a starter kit including a ratty out-of-date database, but it's still annoying

[dusty citrus]

Ponzi schemes?
Since it's the time, maybe they're using some llm, or slaves/cheap people from third world countries

[burnt tendon]

Yah, but you can't ponzi scheme a LLM or exploited person from a worse-off country the way you can a sucker in your own country?

[late fulcrum]

Not really Ponzi schemes as much as low-risk, high random payoff (they get some serious money if they refer someone that gets hired)

So they just throw everything at the wall and hope something sticks. Once you know this, you can take advantage of it.

[burnt tendon]

Mostly the thing I was wondering is what would happen if I tried to use California's privacy laws against them.

[dusty citrus]

Tbh I barely get any serious job offer
It's always some scam or bordeline scam (sweatshops or undefined colabs)
And since I am not a people person, or aware of current trends, I struggle to bond, so in the long run is problematic
All business here, seem to live on eu/state bounds, which are also a pain to acquire due to burocracy. Then pay the employees the less amount of money as possible or get unpaid interns

[late fulcrum]

That's a valid point

[burnt tendon]

Because, having gotten suckered into dealing with interfacing with data privacy compliance efforts at a past job, one way to cause someone to waste a lot of time if you are in a region with data privacy laws is to trigger all of the hard workflows, like requesting someone edit only pieces of your information, which means that someone is going to have to potentially do a lot of things.

When I needed practice interviewing, I circulated my resume to a bunch of sketchy headhunting firms. I got sent to lots of interviews for jobs for which I was completely unqualified. I went anyway, getting practice interviewing when I didn't have an emotional investment in the result. When I started getting offers, I realized I had leveled up in interviewing, and then started targeting jobs I actually wanted, with the ability to relax and interview well.

[dusty citrus]

Eh I don't really think that they care. Even if you are able to do something against someone, they'll quickly find a replacement

[burnt tendon]

Unfortunately, the Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses don't quite pass the unwritten interview dress code.

[late fulcrum]

I actually have a pair of peril-sensitive sunglasses somewhere. I should try that sometime.

They came with my InfoCom "The Hitchhiker's Guide to the Galaxy" game, back in the days when games came with a bunch of fun fluff, so you didn't feel so bad for spending a bunch of money for a floppy disk.
