That's easy done... but the tree out front is a more likely target. 😛

I just killed a Pi Pico by feeding 6V into one of it's pins
the chip now gets super hot when powered on
BUT
seems like CircuitPython still runs fine and I was able to copy all my codes from that pico to my computer safely
how is this even possible?
IIRC the RP2040 doesn't have onboard flash. Code is loaded from a separate flash chip, which was presumably intact.
so even the GPIO is fried the CPU, QSPI, and USB module are still intact
and was able to load CircuitPython and transfer the data out
They are likely running in separate power domains, but yeah that is surprising.
yeah
Hoping I don't end up frying one of my LoRa boards... 😅
That is a risk yes. The bigger the metal footprint the more likely it'll get hit. If your lora board or any board is directly attached then you have to consider it a consumable.
Very large antennas have a spider web of grounding metal laid beneath the antenna before construction on the antenna even begins.
The bigger the antenna the bigger the grounding web.
They're usually buried a couple feet under the ground so you never see them with large antenna... but they're there, underground.
I'm restricted to a shed or chimney-mounted antenna, so I'll have to take the risk. 😛
Welp, im out of the minivan club
Not even a week of ownership and it starts showing transmission issues 🙃. Returned it to carmax and used their 30 day return policy
I did that yesterday, and today I bought a car from Subaru because at least they’re decent cars that I’ve not had issues with
Oof
... which in turn originated from the Intel 8008
All cars have problems. Anything mechanical will wear down over time. That's just the nature of friction. Even water will cut through rock given enough time.
Your best bet, especially if you want true RMS and the ability to deal with a high crest factor, is an HP3403C.
It depends on how elastic your definitions of "non toxic" and "spray paint" are...
the janker
The Z80 architecture is still going strong as well, just the plain Z80 chip itself (like the 8051 long ago) will no longer be made. Versions of the 6502 (well, now 65C02) and 1802 are still being made.
huh, looks like it's primarily the 40-pin DIPs that are being discontinued. other Z80-compatibles (including by Zilog) look like they'll still be available
yes, but some cars are very much worse than others.... like audi ;x
haha
Indeed
Sure, but apparently the issue is so prevalent that Honda made a software patch but no official claim about transmission issues
I wasn’t about to have a van that would spend a lot of time in the shop for the transmission
honda odessey?
Yep
new ish?

dont think ive known nayone with an odyssey
2019
everyone i know with a civic is happy
Apparently the issue is worse in the newer odyssey’s too
There is currently a class action lawsuit that was filed in October last year about it
ah
Anyway, I opted for one of my favorite Subarus, an Impreza
I’ve owned a few over the years. I’m kicking myself for selling my really nice Impreza sport last summer. They discontinued the sedan version so only hatchbacks now 😢
Not that the hatchbacks are bad, the sedan just looked sportier
my friend was selling his impreza wrx a while back. (quite old one, first one i think) he still got pretty good money out of it
err, they were all 4
There was a small number of 6cyl made
WRX was just a tune package
It was either a Legacy Sedan WRX or Legacy Outback WRX
From my understanding, the 6cyl may have been Japan only
I don’t know if it ever came the NA or EUR
this was the impreza wrx
Lol
then they went to the bug eye one
blah
i found a 50A power cord/outlet/inlet set for my shed. $400 plus tax roughly. that opens some options up
ooh nice
Very affordable too
was it new?
I think so, they dealer even offered before to source cars from other local dealers too when I went I last month looking at their 7 seater SUVs
29k cdn here. (although im sure theres 10k in options it needs)
Mine is a sport so not a base trim
My outback is a base trim but very well featured for a base
The window sticker says Sport/RLD
we have some weird laws so our cars are sometimes different. like they have to have a trim with no AC
Oh wait maybe it has eyesight
wrx is 36k
with heated seats, hehe
(i think heated seats on on most nicer cars up here cause brrr)
Yeah, they are nice after a long day
There are southern US versions of some cars that do not have defroster lines in the rear window. No need.
That's a gorgeous car. choo choo.
I bought 2018 Subaru Legacy off the lot and have only had 1 odd issue that came up - radio amp froze up and required pulling the fuse to get audio working again. Other than that, been really happy with it 😁
I really easy on cars too, which is what made the van transmission issue a no go for me. My 2021 Outback has just shy of 27k miles
Bought it new with like 5 miles on it
Only weird thing is sometimes on really hot (100°F+ days) and colder than 20°F days, the radio and ac control displays restart themselves
Probably just needs a software update or something nothing critical to operating the car
thats a glitch in the matrix.
shoots the cat
This is a great recommendation thank you
I was looking at their older models
The 400EL GL FL etc
It's funny because I know way too much about cars but at the same time I don't actually want to deal with a lot of the car things, therefore my spouse and I share a care that's basically hers.
The WRX always did look like fun tho.
it's really sad when you have to reboot a car because some process hung
like TVs, cars have become too "smart" (narrator: Not smart)
Not the car, just the ac and media interface stuff restarts. Car still drives
NYT had a follow-up article today about how car manufacturers are sneakily enabling location and personal info collection from cars and sharing it with data brokers, insurance companies, etc
I just can’t change the volume or change the air while it hangs
subsystem reboot
Yup
It doesn’t happen very often, but it’s usually when im trying to get the AC on because it’s 110°F+ inside the car
I've heard some of those can be picked up by 433MHz LoRa kit..
Seems a little silly.
I don't know if it's LoRa per se, but it is 433 MHz (but I think you trigger it with 125 MHz)
TPMS has been around for a decade or maybe much longer
Not surprised. They won a court case recently that allows them to do it.
do you know the specifics? my assumption is that companies that have access to our data will abuse it unless it's specifically against the law ...and even then sometimes
(in the US at least)
Ok, they didn't win per se, but a judge dismissed the class action suit.
Only thing a horse is going to steal is my bucket of oats and apples off the apple tree
I was surprised how much horses love steel cut oats. My parents boarded someone’s horse one summer and we went through a large bucket of them in like a week
I guess their decision to board the horse led to a lot of re-groats.
Very interesting
The US just passed an anti drunk driving law requiring cars to implement measures to detect drunk driving behavior. As a nasty side effect, the law allows cars to do so by uploading all sorts of information.
all of that data could be processed locally on the car
but everything is for sale now, so get it while you can
How could I find this out on my own
I've been looking all over
I wish there was a way to look for every ac voltmeter way
I happened to find out about it in one of Jim Williams' fabulous application notes https://www.analog.com/media/en/technical-documentation/application-notes/an106f.pdf You can learn some really useful things from his writings (and those by Bob Pease).
It does include a short table of such voltmeters.
Yea I'd be interested in a homebrew implementation
I ended up buying it because I'm deriving heater voltages for CRTs from auxiliary windings on flyback transformers and measuring that high frequency, high crest factor waveform accurately is not easy (modern voltmeters can't do it).
That's one way to unwind.
more than meets the 👁️ ?
how to interface the sound board to the arduino and make it talk with the sound board?
Personally I would like to see an anti-distracted driving law with some actual teeth. Like, start revoking licenses a month at a time for violations.
Don't need fancy AI to detect spaced out drivers. Did I just turn 80 degrees or more, were my blinkers not on in the past 15 seconds? Release the fart gas...
(I see the fault in these heuristics and methods, but I'm not a driver, so I might vote for it anyways)
I do drive, and I avoid driving in favor of riding my bicycle. Driving is, by far, one of the most stressful activities for me.
I am onlycomfortable driving if there are no cars in front of, behind, or on either side of me. I consider everything on or near the road to be a safety threat.
The lack of accountability is the largest reason people drive their 2-3T death machines recklessly
Personally, I wish it was easier for me to take the train or bus to work
Or living closer but that’s too expensive
Cars really are death machines
These new touch screen controlled cars just make it worse. You have to take your eyes off the road to see what you're doing. I continue to insist on physical knobs and switches I can operate by touch.
Another reason I want my dad's Triumph Stag. 😅
Howdy I know this has been addressed B4, but is there a way to turn off the SPI display from showing the serial output like the REPL when the code is stopped? So that the display itself retains the last screen? I use the serial monitor in MU or Putty, so I would like to deactivate it going to my TFT displays? Thanks.
You could just add a blank tilegrid object to it at startup
I would imagine you’re going to use it to display something anyway
I don't think there's a way to retain the last screen when the code isn't running (unless it's epaper)
maybe displayio.release_displays() would at least not show the repl
Maybe you can save off the last state and load that on boot
if you catch all exceptions and print traceback to serial for debugging, the display never goes to repl on errors
Thanks guys will do.
Hey I tried out the ESP-NOW yesterday that was in the latest Python on Microcontrollers email - very cool and easy to use. I'm sending byte string from Feather ESP32S2 to a Metro ESP32s2 with a TFT to show the data. All connectionless wifi, Nice.

Did the adafruit jobs board go away? I remember picking up side gigs on it and posting positions when day-job was hiring.
We were going to revamp it, but that has not happened yet. No schedule for that.
Aw dang. Okay.
hehe, go a notice in the mail and nutella is hiring plc programmers
Wow, that looks like what I'm looking for, for my project (trailer hitch mounted trike rack)
Guess you got a steel of a deal.
thats just thin steel studs. for building walls.
they are kinda floppy on their own without a membrane (like drywall)
0.5mm thick
Oops, thought it was square stock
One thing I hate is remembering hearing someone say you could omit something, and for whatever reason you blindly trusted that advice and then you spend 2 hours debugging, and pouring over schematics, and the hardware checklist to find out you can not in fact omit the thing and your original design was right. 😪
One more spin and.. $200 more I should be ready to start shipping lattice FeatherWing after re-adding the part I omitted out of blind trust
Lesson learned though
Been watching the terminators and macross plus, both deal with AI in interesting ways
Anyways how yall doin
Fellow adafruitians
Adafolk
Working on a TFT adapter board that will work with a Feather, QT Py, or Pi Pico. Can mix and match addons too.
Gonna put this on the back window of my car
Pulled the trigger on 5 PCB's. Will take a while to get here. Next board I'm working on is a Feather tripler on the back of a TFT.
Having the ability to stack is nice but the doubler or tripler layouts are much nicer to work with. They're also easier to fit in an enclosure. Vertical stacks means your enclosre has to be deep.
Plus the horizontal double header rows offer a lot more available pins for ground and power.
looks like one of those secret cheat codes for a console like PS5 or Xbox
The one I shared is the 500kg bomb eagle strike in Helldivers 2
The one madbodger shared is a cheat code for the nes
this is my pixel art
I like "fruitians" -- sounds a bit like the Futurians (of whom I was exceedingly pleased to have met about 50% of)
For whatever reason, I find tall PCB stacks quite exciting so I go through a lot of stacking headers.
I do the same thing... stacking headers on almost everything except displays, and storing similar boards as stacks
I have been using the Feather doublers, triplers and quads instead, in some cases. The stacking header pins are not as sturdy as I would like.
i do wish Adafruit would stock stacking headers with square pins
i've found them on DigiKey before, i think. probably listed as having "wire wrap posts"
i mostly use the jumper housing kits to make custom jumpers these days, instead
The thinner pins on stacking headers don't stress solderless breadboards as much as the square pins do
Need double stacking headers for the Ethernet Featherwing...
Or taller ones
Are there taller ones?
I've seen extra long pin ones for dual row, presumably they're available for single row ones as well
Moar post today. 😁
this is fine https://www.thingiverse.com/thing:5923686
I work in the tech industry and this meme/comic, much like everyone else, has become a visual representation of the chaos we are subjected to on the daily.

I think my cat is some sort of AI/android
Like I bought something it never saw and it froze for 2 mins in front of it trying to process what it was/how to interact with it
as if my cat OS was rebooting because it got stuck in it's AI thread or something
I had to pick up my cat because I thought it was paralyzed or something
What channel should I ask questions about the circuit playground bluefruit app? I'm having trouble finding the device on my android phone.
...hmm I'm thinking the circuit playground might not be compatible with it
apparently i got lucky and managed to not destroy anything by hooking up my level shifter chips backwards! they got really hot for a while though
#general-tech is ok . what device? If it's running CIrcuitPython, #help-with-circuitpython . #help-with-radio is ok too
solder sucker or solder whick
i have solder wick
one issue that im running into right now is the solder wick does not seem to wick
ok cya
hey i just changed to it, still waiting for it to heat up
took a bit long to remove it because 🔥
@solar halo iyo, which solder tip is best for soldering header pins?
either of these
400C is way too high for most things, if your iron can actually hold temperature 350C should be maximum, I solder at 330 (30C above my solder's melting temperature).
I have tried using wick with such irons and the most functional process was like:
- heat up the board somehow
- heat up the wick (I used my gas stove :S, a bit dangerous)
- place the wick on and around the joint
- add flux and heat with the iron, try to get it to flow on the wick
- change the wick when it has absorbed some solder
Try not to cook your board though, it shouldn't reach 400C anywhere.
if you have good solder wick and a good iron you should not need to pre heat anything
Not always true, some boards with large ground planes can give you a lot of trouble without preheat. Signal traces generally shouldn’t need preheating, but never say never…
thats why i said should not
Temperature would depend on solder type too; some lead free solders may need close to 400, but for most solders 350-370 will suffice.
i usualy use about 360 as i use leaded solder
Try cleaning it with a wet sponge. The black stuff is almost definitely burned flux, which will make heat transfer much less effective.
If the iron doesn't have good temperature control then not preheating anything will make using wick (that's very thermally conductive) very painful.
Also I didn’t scroll all the way up earlier, but did you say you were using paste? I’d strongly advise using solder wire instead, a lot less excess flux to contaminate your iron tip.
@thick wind the tip is black because i dunked it in a cardboard box earlier
is there any way to clean it? the brass doesnt seem to do anything
i do not have a sponge
the solder does not stick to the tip btw
I have a QUECOO T12-956 Iron right now for your standard dip package chips and thruhole stuff. I want to also learn the ch32v003 platform, those chips are packaged as TSSOP16 and QFN20. I saw this station come recommended for working with really small stuff https://www.aliexpress.com/item/1005003149950965.html My question is, would it be obsolete if I just got a hot air gun instead https://www.aliexpress.com/item/4000406235877.html. Or do I even need any replacement
Tip tinner?
Once my iron explodes like the previous one ill upgrade to a proper soldering station
the wick does not work for me so i may probably look at that again in the future
it may be that i picked the non-flux wick
so i just heat up the pins and used a toothpick to manually remove the excess solder
you can use a wet paper towel
I'm looking for a water flow meter that I can poll with an ESP32/Arduino/etc for its values. In this scenario, I don't want to do the pulse counting with my controller and do my own measurements, I want to poll an existing meter and check for its values and transmit them out. Does such a product already exist?
I considered getting just a flow meter with a digital display and snapping a picture of the screen, or, taking one of those apart and checking what they're attempting to display.
first thing that popped to mind (because i'm looking at one) is a rotary encoder like https://www.adafruit.com/product/5880
its the circuit playground bluefruit
Can anyone please help me in how to connect my raspberry pi pico midi controller to ableton live?
I have assembled the hardware and I'm stuck in here
And also I've done few changes in my code that was given in the adafruit website for the pico based midi controller, it'll be of a great help if any circuitpythonistas can help me out
@solar halo i actually have two stm32 blue pill, this time i carefully soldered it
turns out pretty good i'd say
the flux has been removed after the picture was taken
Try asking in #help-with-audio
one thing i just noticed is that the reset button differs on both boards
and one blue is lighter than the other
@late fulcrum @glad ruin either of you fellas familiar with GPIB?
trying to acquire some bits and bobs and found 2 ethernet to GPIB adapters for 30 bucks
wondering if they are even worth getting but i am not familiar with GPIB
i do want to use it tho
Just only know of the Arduino adapters
I've used GPIB on and off a few times over the years. I'm not familiar with the Ethernet adapters, but I've seen serial-to-GPIB and USB-to-GPIB adapters. It's basically a simple parallel bus, which can talk to devices, each of which you assign address to so you can identify it.
I actually wrote a device driver for a VME to GPIB adapter, but that was a long time ago
its an IEEE standard right so if i just get it then i wont need some crappy software to use it correct
i found the service manual for the unit and no mention of much
usb to GPIB is a lot of money somehow
its this fella
currently importing some leader stuff from japan since everything is crazy overpriced and got one of those for 3 bucks
GPIB is an IEEE standard (IEEE-488, based on HP's HP-IB, which in turn was based on the Commodore Pet bus). However, the ethernet side of it would presumably be implementation specific (might be simple, might be complex). And each GPIB device has its own protocols (Tektronix had a standardized set of commands for their devices, for instance). The USB-GPIB adapters I picked up on eBay fairly cheap (<US$30).
ah yeah nothing is ever simple
thank you
i really should just get those arduino to GPIB adapter thingies
i will take a look at some USB GPIB stuf
i got a 31 page manual for it
I'll have a look at the Arduino ones (I haven't seen those before, but I'm guessing they're basically a pass-through like the VME one was, so you'd set up the data you want to send, then use some pins to operate the flow control signals
Manuals are a big help
Looks kinda like BASIC (which would be reasonable)
it is indeed basic
Seems like it has more smarts than just a pass-through, so you send it a program somehow and it does the sequencing for you. I'm used to "dumb" interfaces, where you do everything a step at a time.
alright that makes sense
Just because it's for a power supply doesn't mean you can't use it for other things (that's an advantage of GPIB, it's pretty generic).
ive been trying to score a cheap audio analyzer and it has been terrible financially for me since there are a lot of cool tools to buy
might be worth then
im reading the documentation for it
trying to see if i can
Wow, I just looked up the USB-GPIB adapters I have. They're the Prologix ones, and they're like $140 apiece these days. However, there are no-name Chinese ones for $31 or so.
yeah the prologix are big money now
I wonder if the serial ones are worth anything (I doubt it)
this is the manual for the power supply
i assume these are all the functions it can do
SHI, AH 1, TEO, L3, LEO, T6, SRI, RL1, PPO, DC1
DTI, CO
Look at NI. They're like $1500 (minimum).
what
4 digit?
i just have a bunch of measuring instruments i want to be able to use at the same time as a HP8903B
and then i can do datalogging
The VME one I wrote a driver for was NI. You can pick up the NI ones on eBay for $50 or so

Just got ding-dong-ditched... twice, 45 minutes apart. Gradeschool-aged kids. Do they not know a lot of people have cameras, or just not care? Though mine isn't obvious like a doorbell camera is.
that's still a thing? how... last century 😏
yeah, I don't know if that's happened here... ever? at least not within the past decade or two
They are mad at you for stealing all the internet in the neighborhood with all your devices connected together...
nice!
There are some adolescents in my community that thought ding dong ditching was the done thing. My windows were open, I saw them. I talked to their parents.
Lol..
It wouldn’t have mattered much except I had a newborn (now 1m old) and my dogs freaked out and about landed on my mother who was holding her at the time.
It's for the trill / show off with the friends who has it longer.
Or at least that was it when I was younger
Never been a fan of it, but peer pressure 🤷

How do I send a request to John Park for his Workshop?
Anyone know why IO21 is connected to 3V3 with decoupling on Adafruit's QT Py ESP32-S3? Literally no documentation from espressif on this
Not clear at all, on the Feather it's the NEOPIXEL_POWER output, and on the Feather TFT it's the TFT_I2C_POWER output. Maybe a vestige from some earlier design.
@rapid geode @late fulcrum
I got my custom motors finally
Got them balanced and carbon brushes instead of the crappy metal ones
Also got some done in ball bearings
I will soon enough
Be the owner of 500 of them
oooh
That is a lot of custom motors! That's really cool!
Google ripping out risc-V from android: “no, no. Don’t worry. We LOVE risc-V. It’s amazing, and we’re gonna support its development!”
what do you plan to use them for?
Tape decks
For their cam control motors
I'm gonna sell the rest to break even
These are all the ones
Left to right
CD spindle motor
Too weak and too fast
Original motor
Dies a lot
Ignorance: how much did it cost to make them custom?
Also what's the point?
Red winding motor is a clone of a RC370CA which sucks as a clone cause it's of poor quality
And it requires a lot of grinding for it to be bolted
And has crappy brushes
My version is balanced so it will last a long time
Requires no grinding or cutting to fit
And the brushes are carbon which is much better for this application
on meeelion dollars
runs
45 bucks for the pre production samples
1000 for 500 motors
Plus shipping and duty tax
Cheap I thought more

Lady Ada made a board that looks like it is a game changer for the Assistive Technology community, helping disabled people to interact with devices. This video shows how much they appreciate it and the potential: https://www.youtube.com/watch?v=cFSRqEwLhbQ&t=2369s
Let's get together and chat about the new Adafruit TRRS Trinkey and just how useful it's going to be in the ATMakers world. I'll show off a prototype & be happy to hear ideas about how this can help.
I'll share the Streamyard link in the comments at launch time.
I thought my MacBook airs usb output is 900-1500mA which should be enough for an esp32, it's not being powered though
technically those current specs are for SuperSpeed and higher, i think. high-speed and lower are limited to 500mA by default, per USB-2.0, even on a USB-C port
Ty
if the specific board has USB-C, it might be lacking the CC resistors to tell the host to turn on VBUS (common bug on cheap designs)
Hello everyone, I have no knowledge of programming but my goal is to make a clock for my 4 year old son who has type 1 diabetes.
I have seen several similar projects on the internet and I must say that it would be wonderful if the project comes to fruition.
Several projects on the internet recommend an ESP32 card, I ordered a 64X64 RGB Led matrix screen, ESP32 WROVER B 38 Pin, ESP32 WROOM 32 30 Pin. The choice of two ESP32 cards in the event of a reference error because it does not give much detail. (the material was purchased on Aliexpress)
I installed the "Juggluco" application on my Android 14 phone, it allows me to connect to my son's Freestyle 2 sensor via bluetooth and to receive feedback from it every minute.
The Juggluco application has the possibility of creating a local Web server, I tried it and it works, I can obtain the blood sugar level on my Windows computer with the application, this is very useful.
“FloatingGlucose”
It's already extraordinary to have my son's blood sugar on my phone with a widget that updates every minute as well as on the computer.
My goal is to transmit the blood sugar level to the ESP32 card and its 64X64 screen.
I have all the equipment but I don't know what to do, I have never programmed in my life but there is a beginning to everything, I understand quickly.
If there is someone who can explain to me what to do or what I can do with the equipment I have in my possession.
Thank you so much
hi everyone, new here 😄
I'm thinking you'll need four things. The first is a way to adapt from the ESP32 to the RGB matrix, since the matrix uses 5V signalling and the ESP uses 3.3V signalling. Something like https://www.adafruit.com/product/2601 can adapt between them; it's designed to connect to an Arduino, but you can connect it to one of your ESP card with wires, or perhaps find a similar product that is easier to adapt (AdaFruit makes "Matrix Portal" boards that contain the processor and matrix drivers in a single board, which simplifies this process).
The second is software to fetch the readings (possibly from Juggluco). This shouldn't be too hard, but it's trickier if you haven't programmed before. Note that some programming environments are easier than others.
The third is to display the information on the RGB matrix. There are libraries available for popular programming environments (such as CircuitPython and Arduino) to do most of the work. I'd suggest starting with a simple text display and once you get that working, you could consider doing fancier things like bar graphs, color coding, etc.
The fourth is powering everything. You'll need a fairly hefty power supply (perhaps 5V and 4A, such as https://www.adafruit.com/product/1466) for the RGB matrix, as well as power for the ESP board (most ESP boards can accept 5V power and regulate it to the voltages they need). You'll also need the associated wiring to connect everything together.
I wonder if ESPHome can handle it
That's a good thought. I don't know much about ESPHome at all.
If it could, that would be the lowest code solution
Same, never personally used it
I’m not really a smart home person
I'm an old school "smart home" person, still in the X10 era which isn't capable of doing anything like this. However I do enjoy LED matrices, like these I built for our local Ghostbusters group.
ESPHome is pretty magical.
Disclaimer: I am very very software engineer so if I think ESPHome is easy, that's not saying much.
That's super helpful information thanks
https://github.com/joelhi/glucose-viewer-pico might be a good place to start, for the software aspect at least. Although it looks like he's pulling data from their API (didn't look to see if it was local/hosted?)
Question about the tio serial monitor I installed on Win10.
The doc says --auto-connect latest for example, but when I use this I get unknown option. No biggie, just would be nice that when I do power cycle my board, it reconnects... No joy.
auto-connect should be on by default?
Well it says it is, but reconnect does not work for me...
what does tio --version say?
I have not tried tio on Windows. Tera Term reconnects automattically, and is a nice Windows-oriented app
thanks Dan, version 2.7
i also have 2.7 and it's reconnecting properly on Linux, so I guess it's a Windows thing. So you may be happier with Tera Term.
I bought a 5dbi 21 cm antenna for my heltec lora 32, hopefully with that ill be able to get a better signal, if not ill have to go bigger
I also got this jetfire figure

Yes I suspect as much... Thank you! I am happily using the basic Tera Term serial connect and works like a charm reconnect
Very sick
We've been having a problem with our internet for about a month now . About once a day, data rates will suddenly drop from >500Mbps to ~20Mbps. Eventually figured out the best way to fix it is to power down the router and power it back up again.
We have 2 Nest Wifi Pros, model and software version: G6ZUC, 3.73.406133
This morning, I found out 2 new things:
- Google pushes out software updates to these devices periodically, and there's no way to stop it or roll it back.
- A very large number of Nest Wifi Pro owners have been having the exact same problem since 3.73.406133 was pushed out a month ago.
So, if you're having the same problem with your Nest Wifi Pros, have you tried turning it off and on again? ¯_(ツ)_/¯
Heh, my internet gradually slows from 3Mbps to less than one. It turns out Verizon's modems "fall back" if there's line noise, but then never recover, so they just get slower and slower until they're rebooted. I can only dream of even the slowest speed you mention.
When we used VTR as our isp it would spontaneusly die completely around once or twice a week
Oh yeah, sometimes it drops out completely, which is why I have comcrap as my backup unreliable ISP
can please anyone tell me how i can do this https://youtu.be/WBE8IZFu55Q?si=GcFO2DWD9xIrT_B9 ?
messing with a micro-controller manufactured by adafruit! this one is called a circuitboard playground express. i use arduino, max MSP, and VCV rack to design the controller to get it to look/sound like this.
Ah I am regretting to not have picked the programming job over the networking one. Hr are boring
You took a network engineering job?
Or some kind of networking specialist kind of job
Network "engineering" , a cool word for describing a call center with extra steps in the end
Ah, so “support engineering” is what you do
Mostly
Some network engineers do some actual network engineering like planning, testing, installing, and verifying network infrastructure
I also do that, but it's annoying, it's not so different than any consumer hw, just more expensive
Software engineering has its moments where you are mostly putting out fires that other people start.
I spent a lot of time in meetings the last two weeks pointing out that no one planned for a specific requirement that has now led to me having an additional 800hrs of work on the project in leading development on 🙃
So that’s cool
The other job that I may have taken sounded more fun, you basically manufacturer machines that printed on metal
But pay was the same, and would had to travel for 2 hours daily...
But maybe it's just because the grass in the other side looks greener and I am getting sick of my current position after a year
They had a lot of cool equipment, that you dream to see in an office
Well, the grass is always greener. I personally don’t mind my job but there are plenty of days I dream of doing something else
there's no harm in that, or even looking for other opportunities, but there is something to be said about paying the bills 😁
My main motivation for trying to be okay with my current job because the next isn’t guaranteed and neither is the salary I make
i hear ya -- did that one for 17 years (and it finally did pay off)
My next job might be manning the burger station at the local McDonalds making 1/3 of my current hourly rate
😬
That’s just what the economy is looking like anymore
3 years in, working on my 4th.
I did technically leave for like a month and a half in 2022 for a short stint at a startup that ended belly up. But HR made it look like in their system like I never left lol
But they also changed the rules for leaving and coming back after I came back because I went from a L1 making $84,500 to a L2 making $105k
💀
yah, ooops
Yeah. Not many people can game the system and progress to a level 3 in 3 years 😬
There are people who started as new grads before I did who are still only level 2
I played the game and was the reason they changed the rules of the game to never be played like that lol…
But now I have responsibilities, ew
so
I need a life mystery explained to me
my VR headset nees 2 usb 3.0 ports. For some reasons the ones on the front of my computer won't do, even the manufacturer of the headset says so. Has to be usb 3 ports directly on my motherboard. I actually tested it and my Vr headset complains the usb ports are wrong if I try it. What the heck is going on ? What is the reason for this usb discrimination ?!
also why two usbs and not just like my 120V sockets if it needs 2x5V ? Sick of these usb devices stealing my usb ports
front usb are often low current
500ma
a lot of things wont work on them. i assume the vr headset needs 2 x usb for more power
is it possible for them to pulse current or that would be a OS issue ? cuz one of the usb 3.0 port seems to not be good for the VR headset and when I plug a headset in it the sound keep going on and off but a mouse/keyboard in it dont seem to mind
I thought all usb 3.0 ports was specific to 500 ma / 5 V 😦
My understanding of the modern USB standard is that it had a wide latitude in specs in order to get companies to adopt them
rear ports are commonly 2A
Power via USB is... weird. Before USB PD came about, different USB standards had different power specs. If you go strictly by the spec, you technically can't draw more than 100mA at 5V without requesting to raise the current limit. For USB 2.0, the max current per port was 500mA, and 3.0 increased this to 900mA. In practice, nobody really implemented a mechanism to cut power if a device draws more than 100mA without negotiating to raise the limit. Many devices don't even implement per-port current limiting, and those that do can often (but not always) supply more than 500mA per port as long as the total power drawn from all ports does not exceed the capabilities of the power supply.
any idea why one of my usb port pulse ? I cant use it at all for arduino or with an headset because of that ? Also since the back ports provides 2A can't I change my keyboard that require 2 usb plugs possibly to ake sure it gets 1A from front port to just 1 plug ?
Wait, why does your keyboard need to draw that much?
As far as the "pulse" is concerned, a variety of things can cause that. Do you have anything connected to the arduino?
what do you guys use for organizing your various electronics, from small resistors to small devices like multimeters?
I bag them all in ziplocs and stack them in a big tupperware, that's my $0 invested solution
The microcontrollers are in their relevant antistatic bags
oh cool idea
no arduino isnt in that discussion yet but obviously my odd usb plugs cuz issues with that
and the keyboard is a mechanical gaming keyboard they often come with two usb plugs
this one has an oled screen in it as well
I feel like the keyboards dont really need two plug sthought and it's just a gimmick for marketing to make it seems powerful
so the engineers were told to make it uses 2 usb plugs
even though keyboards actually uses like 25mA

I have a Pros kit electronics toolbag for my tools for electronics, multimeter, hammer (to inimidate the electronics when they dont want to work), electrical extension cord with 4 usb charging port for makerspace etc
Thank you all for your feedback.
Given the price of the hardware, I will order 2 Raspberry Pi Pico H & 2 LCD Display Module, 1.8 inches.
I will try to contact the project designer so that he can explain to me how to copy the files into the Raspberry Pi Pico as well as how to get it working because I have no knowledge. Thanks
Hi all.
Just a quick question. Does anyone have a Dandanator MTD? I have one, it has 2 rom's and a SD card reader to place gamefiles (.txz, .z80, etc).
It works great for fast load. But the "normal" load it does nothing. I've tryed the normal and the inverted and the Spectrum just stays on the load "" mode, waiting for audio, and nothing loads.
I've tested on the 128k+2A and on the 48k, same result. Also tested with different files.
And how can we load .pok files on the sdcard?
Thank you
it depends on the keyboard. ones with RGB LED lighting under each key can draw more than 500mA, and sometimes close to 1A (i’ve measured a few)
Anyone know why the Adafruit OV5640 breakout has pins in the schematic connected to pins marked as disconnected in the linked datasheet?

Hello
Hoe can i get more resolution frim the eep ai cam
Without fps loss
I was thnking about external psram and ov5640
But idk
hello team. I'm looking for an eagle library for AW9523. I found the open source SCH and BRD file for eagle for their breakout board (I have 2 from adafruit!) - but I'm wondering where I can find the original library?
ahhh - disregard - I exported the library from their PCB design files. Sorry to disturb! 🙂
the breakout layout may be good for more cameras than OV5640. Note that the title on the schematic is "OVxxxx Breakout"
i have one of those multi-drawer things, which has some drawers with mcu/breakout boards in some sleeves (not og because they get moved around 😁 ) plus a small carry "chest" with 4 covered trays with adjustable dividers

This is the May.
runs faster
rememeber, to escape an angry mob you only need to run faster than your friend.
exactly
The original trilogy is decent (Empire Strikes Back is the best of the three). I-III were all pretty bad. VII and IX were terrible, but VIII was decent. My favorite Star Wars movie is Rogue One.
it's a lovely universe, i just think it's been beat to death -- although that might be a bit hypocritical since i'm hoping for an MCU "reset" of some kind 😏
So, understand I've got one of those forbidden marriages. The kind that's scandalous and a bit unholy and makes people stare at you and occasionally try to ban.
That's right. Star Trek fan married to a Star Wars fan.
(I mean, we're also other things that people actually try to ban)
And I dono, the thing is that the original trilogy is really good. And so there was this time period where Star Wars fans had this perfect trilogy and Star Trek fans had this weird uneven world.
Well, at least Star Trek is consistently weird and uneven 
Yeah, I feel like the Star Wars side of the party really has had problems dealing with suckitude. Especially after they were like "Welp, let's pretend this never happened" with the prequel trilogy only to have the sequel trilogy...
And now gen Z has rediscovered the prequel trilogy and actually likes it.
gen z is just ai. they dont really exist
Uh... yeah, well when your stabdards are dropped that low.
I dono, I was never so much of a Trek person that I had to exclude Star Wars. All fun stuff?
reject star wars, return to hard sci-fi
Rogue one definitely is the best of the more recent movies. The original trilogy are okay in my opinion, episode 1 is my favorite overall behind rogue one.
my dad hates rogue one for some reason
I still don't... Except for few scenes, I find the whole star wars pretty boring tbh
It strikes a different (often more serious) tone.
I’ve watched all of the Star Wars movies recently. I’d say in terms of overall goodness, Rogue One, Episode 1, Episode VIII
yeah
that makes sense
Episode 6 is the better of the original trilogy
Ok, I get Rogue One and VIII being at the top of the list, but Jar Jar Binks The Movie???
hear me out
the clone wars tv show was peak star wars
I know people like to dunk, but he’s great comic relief and plays (albeit kind of nuisance role) in victory.
jar jar is our only hope
Oh, I'm not saying Jar Jar isn't funny. He absolutely is. But I don't consider Episode I to be one of the "best" star wars movies.
To each their own
1 was toelrable. 2 was exceptioanlly bad. 3 was meh, cause it was just a bunch of scenese that you knew what would happen in
4 meh. 5 ok. 6 meh. 7 meh. 8 i dont think i ever watched the whole thing
9 was meh
Overall, Star Wars story telling is particularly flat
any story of "good vs bad" tends to be boring.
thats why batman is always a better movie than superman
cause hes not "good"
Visually, pretty good. Plus fighting with light swords is neat

the ships in helldivers canonically use Alcubierre drives
O_o
I’m getting this on a shirt one of these days
gives the same vibes as
"i didn't ask how big the room is, i said i cast fireball!"
makes me wonder if those shirt-printing places on the boardwalk now have helldivers shirts
has anyone ever seen a sot8 chip holder, like those flash programmers, but that can be 3d printed?
I bet they would
I once tried to have a shirt with a statement written on it
but when I worn it I kinda forgot I was wearing a shirt like that and I thought peoples were looking at me to pick at fight
so I stopped having such shirts because in the moment I didnt think they were looking at me to read the shirt
While a design might exist, I wouldn't recommend 3d printing one. The 1.27mm pitch of SOT8 pitch is right at the edge of what an FDM printer can do, and IC sockets are actually more complicated than they look.Getting good, repeatable alignment and correct mounting pressure will be difficult.
But I can see how it'd be a SOT after design.
Fair enough, thx
Rn i glue them to a piece of protoboard with some standoffs and then manually wire each pin with a bit of copper wire to each pin lol
It's super inefficient...
Hold on-what are you trying to do?
Dump firmware from flash chips of iot devices
Can you link to a datasheet for one of the flash chips?
The 25q128 is quite common
Adafruit even sells a module to use it with an arduino
I thought you were talking about something like this.
https://www.digikey.com/en/products/detail/aces-connectors/50960-0084N-001/21778378
Yea that's kinda what i wanna make...
Yeah, I don't think you're going to be able to print one that lasts more than a few cycles, if it works at all.
Adafruit does sell one also:
https://www.digikey.com/en/products/detail/adafruit-industries-llc/4726/13280267
Alright makes sense and explains why i could find any other projects
I guess I'll have to wait till i can just buy a propper programmer and the specific socket, for now, manual laber it is
Thx
Hi folks! I was wondering what the best channel/thread would be to discuss the now discontinued IOT printer V2?
I just got one from a reseller and I kinda want to repurpose it with a pi zero 2 w to do the original kit purpose, with a few twists and I figured where else to ask but here.
Thank you!
I would probably recommend #help-with-linux-sbcs as it's related to a Pi
Finally processed my H-alpha solar images
That sucks, it looks like something got in the way of your exposure
Clouds, but it is good enough
neat
I've tried asking this elsewhere and gotten no luck - basics because probably not the right channel but I don't see an appropriate one. I've found a script to run on a Linux machine (could be an SBC, or even an SBC cluster, but right now I'm just running it on a "real" Linux machine) that I'm trying to modify to behave exactly as I want - shell script, not python or perl or anything like that. If I CAN get it working correctly, and i understand how they work I'll probably be building a Pi cluster for it. Appropriate channel?

oops didn't realize that was in live broadcast chat. 😬 well my neighbors had a good time last night and i got some carnitas. delicious.
Sounds like a good time
Haven’t seen this favor in years
Got a question for yall....
I am in need of something specific. I need a usb cable that is about 20 ft long and will only be used for usb data. What my plan is I have a corsair K95 XT platnum which the cable has gotten trashed on it from being moved. I set it on my lap while sitting in my recliner in the living room. Anyhow, The problem I have is I need to pass not only 1 usb for the keyboard but also usb passthrough to the keyboard for the mouse port/usb wireless receiver. I know the USB C can pass multiple devices through (I beleive up to 4), But which cable? What do I look for?
I found an OTG which has what I need. 2 usb A to 1 usb c. But i need it to be a bit longer.
I would rather use usb c all the way and just adapt the breakout board in my keyboard to the ports
That might be tough. USB really isn’t meant to be operated over more than like 6-8ft. Powering is fine up to like 10ft, but anything more than that can cause signal integrity issues.
Does Adafruit have a small device that can be used to pick up an WWVB (https://en.wikipedia.org/wiki/WWVB) signal to grab the date/time over the air? Thanks!
WWVB is a time signal radio station near Fort Collins, Colorado and is operated by the National Institute of Standards and Technology (NIST). Most radio-controlled clocks in North America use WWVB's transmissions to set the correct time.
The normally 70 kW ERP signal transmitted from WWVB uses a 60 kHz carrier wave derived from a set of atomic c...
Yeah thats what I was afraid of. Though I do have a few devices I am using on 10 ft just fine.. I know its not much father than that but 20 ft.... eek
You’d likely find better results using a Bluetooth keyboard/mouse set though they aren’t really my favorite. (I prefer wired myself)
Yeah i thought about that but i dislike bluetooth crap with batteries
Plus i really love my k95 xt keybaord
IFF i could convert it to bluetooth
and still make use of passthrough port for my mouse i may be interesdted
hmm.. now the gears are turning.. because that would be sweet. Not having to worry about wires breaking. The k95 if your not familiar has a fat a** cord that is stiff and a pain
Ignore the finger that was nearly cut off haha
Its a nice heavy duty cable but still cheap chinese wire 😢
I suppose I could use this...
rip the casing off and make adaptor for battery
Left over carne asada meat. Lunch is going to be good this week 🤓
mmm
SparkFun used to https://www.sparkfun.com/products/retired/10060 but they retired it because they can no longer get the modules 😦
ah well
It's OK. If I was more motivated, I'd have filmed my Voron in the sink yesterday for it's serial number request video.
ok, i'll bite -- why is your voron in the sink? seems like a real drain on resources
Perhaps they had a sinking feeling all their money went down the drain?
Or perhaps they were printing a plug lol
Sorry for the question, but is it a good idea to put the LTR390 outside? Will it damage right away? I don't know how to protect the from the rain
The sensor itself is probably okay, but i would definitely add some protective housing around the rest of the PCB.
Maybe a rubber seal around the sensor
Thanks, I have the protection of the pcb board and the rest of the sensors, but I want to have pretty real uv data and I don't want to use anything that can block the uvs wave spectrum . I've been thinking about quartz glass, but it's hard to find it
Ah you mean the LTR pcb
I'll try to tape it up somehow
You could put some conformal coating on the PCB. Just put a small piece of masking tape over the sensor face
They have spray on conformal coating that would work well
Then you wouldn’t really need any water tight seal around the sensor and the PCB
MG Chemicals sells some that’s fairly easy to use
Thanks, I'll look at that
Because it was sinko-de-mayo
I thought maybe you were starting a new 3D printer 2000’s boy band called “In Sink”
plumbing the depths of that thought...
Yeah, it's just that I had a bunch of things going on last weekend and I felt like it would be too draining.
huh?
Hey all. I'm a little surprised at times when folks ask how "interrupts" work in CircuitPython, or how to "multiple thread". asyncio is the answer and easy to use. The result of a lot of coding hard work I can assume. When I first started using CP, I had several RFM69 breakouts, and to poll the radio to receive, I quickly found the learn guides for asyncio and it works perfectly for having a "polling" function simaltaneous with anything else - like changing a display, doing a neopixel rainbow, etc. Just my 2 centavos.
haha
Hey folks! Not sure if this is the right place, but I wanted to introduce myself, see if there are people with similar interests, and maybe ask for advice.
I have a PhD in math and I'm fresh out of the academia after almost 6 years of postdocs. In the past few years I've been playing around with electronics projects, Adafruit products, Arduino, RPi, and so on. As I'm looking for a career change I've been wondering if there may be opportunities for someone like me that involve this passion for electronics projects.
So TL;DR: are there others in this community that have a similar experience (PhD in pure science, bunch of postdocs) who left the academia and merged their passion for tinkering with their career? (I'm based in Toronto, so bonus points for that, too)
It might be though, but looking at tech companies and their research divisions would probably be a good place to start.
Apple hires a ton a ph.d holders
Finding something not research focused will be hard. There tends to be a little animosity towards phd holders in typical rank and file engineering orgs if the person is coming in from outside the orgs and is what would be considered a “fresher” (someone with little or no industry experience/background.
It’s kind of an interesting phenomenon
Wow animosity even
Better go warn my partner as she works on her doctorate. 🙂
Yeah, it’s worse in some places over others. And it can vary wildly in large companies too
I would have thought that math might have been a problem, not the PhD part.
A stem ph.d is viewed mostly equal in technical post doc roles
You’ll see for post doc SoC verification roles for instance, they are fine with any technical or stem Ph.D
I heard a marine distress call yesterday from my SDR and heard the boat multiple horn trying to avoid a collision as well
Nice
Well, that you were able to pick it up. Not nice about possible boat collisions
Collision didnt seem to happens. Not sure it classify as an SoS more like a panpan ? he distress was they both wanted to know what to do and make sure both cargo ships would stick and not deviate. I checked it on a marine traffic tracking site and it showed one of the ship was at anchor as close to the beach while the other passed. They were both going to pass under a bridge at the same time initially I think the bridge is only safe to pass in the central section and that is like a 70 ft width ?
Just the first time I hear such panicked use of a ship horn several times in a row
I saw nothing on the news but normally but a non-casulaty incident it takes months for even the news of the investigation to show on transports canada website
Finding an "electronics project" job may not be so easy, regardless of your qualifications. Certainly there are engineering design jobs, or software jobs, but these may not scratch your itch. Given your math background, maybe a lab job where you can provide a statistics and data analysis background, and get to build lab equipment for that. For instance, I know someone who worked in a neurology lab that needed to design measurement equipment, and then analyze the resulting data.
If you like teaching, maybe you can find a position where you teach building projects. John Gallaugher at BC does such work: https://gallaugher.com/. Another example is the EEOC center at Tufts: https://ceeo.tufts.edu/. (I know of both groups personally.)
Resarch labs in industry or government are also places to look, as mentioned.
I am also a math PhD, but I stayed in academia, so I am doing all my electronics projects strictly as a hobby - thus, can't be of much help.
Of course many math PhDs go to software, but usually it is big companies - Facebook/Google, which is very different from tinkering with electronics.
Huh, as soon I updated my resume to, I am looking to a work with an indefinite time, and I am NOT interested to apprentice/interships, work agencies and other fugazi things, I stopped receiving calls whatsoever
teh world is 99% spam. what do you expect?
even linkedin has succumbed to the dumb 💩 -- there's games available (smh)
LinkedIn has been in a downward spiral ever since Microsoft took control. Perhaps before.
remember plaxo.com ? 😈
Nope
Exactly...
heh - that was microsoft's first social media attempt
I deleted my LinkedIn account a year or so ago.
LinkedIn has been the source of incredible head scratching. Being peppered with connection requests for things I have 0 influence over at my day job
i left mine up just for grins and the occasional notification about former co-workers
This morning it was “let’s talk about storage and networking challenges at your company”
I have nothing to do with anything IT at my day job lol
Yeah I got tired of the email spam, and found the culture of "thought leadership" fosters to be toxic.
I just use it to document projects for recruiters too lazy to check my GitHub
And I have a page for my little edu hardware company
Any recruiters too lazy to do that are not worth my time.
I got a job from doing it so 🤷♂️
Granted that company went belly up when the grilling industry flopped in the summer of 2022
Lol.. but I also had another offer shortly after that from what I posted. It opened the door at least 🤷♂️
Basically
recruiters in my industry are the type of people you dont want to associate with
😛
Recruiters in general are the type of people I don't want to associate with.
That’s not a very fair generalization.
I know plenty of people in recruiting that are genuinely nice and decent people. The job title doesn’t make them inherently unpleasant people.
They’re just trying to do a job like the rest of us.
true -- but to be honest, most HR types really don't speak the same language that engineers do (i'm not saying which is closer to the "norm" because we all know engineers are a bit 😜 )
Hr should be Ihr, inhumane resources. They have no experience whatsoever in the field, base themselves upon bs, while leveling up themselves.
No I won't do your 1k "behavioral" test questionary. If you "vibe" with them, then you get a contract porposal that's like minimal wage but it's not stated before hands because NDA (bs)
Not everyone is the same, but that's my experience.
I think it comes down to there being poor communication between recruiters and engineering managers. Plus trying to balance the requirements for screening imposed by upper management, et al.
You also have to remember that HR isn’t there for the employees, it is strictly there to protect the company from liability and manage headcount
They manage Human Resources (I.e.: labor)
It’s human, not humane. One is the being, the other is treatment of the being.
Indeed, but how can I say, many are massive i...s; There are some questions that I really dunno if they expect me to be sincere about it, or lie
And yes there are unsavory people working Human Resources that live to extract every ounce of human productivity for a cheap as possible for their own enrichment. But most are just everyday people trying to put bread in their pantry
Many are working with the tools they are told to use. It isn’t necessarily their choice to have you do a 1k questionnaire to see if you licked paint as a child. That decision was likely made by C-Suite execs who went to a retreat in Bali to hear how to optimize hiring through channeling their inner hedgehog from some self described guru who’s parents are VPs at insert big corp here.
Agree. Anyway, isn't there a cheap, small (<30€) dual sim lte module, with great documentation/libs?
I've found this thing, but I see that it has problems, and it's not quite a sim800 module in dimensions:

Like?
Dual SIM support isn't common in modules like this. Do you need 2G, 3G, 4G, LTE, or 5G connectivity? There are some seriously nice modules out there, but they aren't cheap. Also, modules are specific to various band plans in different parts of the world.
You can, of course, add SIM switching externally.
4G/lte/5G, anything that works those days really, and well documentated/great libs. But it must be <30€ . I was right now taking a look at https://www.arduino.cc/reference/en/libraries/category/communication/, so maybe I could find some kind a cheap compatible knock off
Maybe https://wiki.dfrobot.com/A9G_Module_SKU_TEL0134 or SIM7022?
Wiki: A9G is a complete quad-band GSM/GPRS+GPS module, ideal for IoT applications for home automation, industrial wireless control, wearable electronics, wireless location sensing devices, wireless location system signals.
This is called HR AI chat bots.
my friend was telling me that resumes are all filtered with ai now. (whihc i know isnt true, but i expect is being used at some larger firms)
Automated resume filtering has been a thing for years now, and it has always been pitifully bad. It is likely done via third party platforms such as workday, so it is by no means limited to large firms.
Yeah, it’s been used for at least the last decade. If you go back to even the late 2000’s they were already doing key word filtering on resumes
And it is horribly, horribly broken.
thats nt what im talking about
AI resume scanning is basically doing the same thing. You can trick it with white text blobs
I think AI should be renamed
It’s not intelligence by any means. Nor is it really artificial since it’s trained on data from actual intelligence
yeah
The hiring process is a pain point for me. I've found that it tends to filter out people who are neurodivergent.
It also doesn’t help me that because of the nature of my job, I can’t actually quantify my work
That would suggest that it actually augments and improves human thoughts, which...
this is similar with mine. its more complicated than a list of tasks
They want to know how many dollars you drove in value but I’m not privy to that information nor would it be ethical for me to share it
how many dollars you drove how on earth would you know that unless you were in sales
The notion that "value" can be measured directly in dollars is... problematic.
Like do I put “I made the company spend 800hrs into new scope that was supposed to be bid by other groups but glossed over until the software org said ‘fine, we’ll do it’”
Quantify your job:
“I deleted 20,562 lines of code”

Pushed it to its limit and also tested the fire suppression system
i drove to work in 4 ft of snow?
Someone at NVIDIA could actually say this.
Tbh, I feel like it would be pretty fun to see that happen in a controlled environment
Only if it was uphill both ways
my job is more straight forward. client needs x done. how much will it cos. client says yes. ok, do it. it is on time? no. why not? cleint changed scope 45 times. ok.
'value" is more avout CAN you actually do it.
“Delivered a pile of heaping garbage that the client loved for 20x the original cost”
ugh
sometimes that strue sadly
other times i get emmy nominations ;cx
sometimes both
hahahah
Based on many of the shows these days.. I believe it
Though 3 Body Problem on Netflix is fascinating
The story is a bit messy but not so much you can’t sus out what’s happening
I like the overall premise of it at least
HBO is empty these days
i donbt think ive done any hbo
Thanks to them killing and deleting like 80% of their good content
usually amazon and netflix
Amazon lost a ton of subscribers due to their “even though we promised we wouldn’t charge you money, you have to now pay $2.99 extra for no adds.”
im not sure what ill be on when things pick up again. possibly something marvel
That’s because AWS isn’t the money fountain it used to be
ah yeah
company i worked for 20 years ago sold to amazon who then freewared everything in hopes of aws usage
Boeing.
haha, "poor" boeing. boing IS bad, but remember so is airbus. boeing just has all the attention right now
Indeed
what i want to come out as official is that air india and pan am were door latch failures, and not bombings. (they already released the air india suspect cause there was never a shred of proof)
i think in part it was one of those "whats better for the public to think, someone bombed a plane, or that the planes have doors that just fall off"
I didn't hear about either of those cases.
pan-am was scotland, air india was toronto. door blew off, hit engine. "why" did door blow off is they mystery. a small bomb and a latch failure would kinda be the same result. in both cases they found people that had the access and desire. "case closed". so not really a conspiracy, but, as it turned out, possibly not the right conclusion
many years later twa 800 went down with the exact same door latch failure, except this time it was on film. not long after the toronto airport worker they arrested for the air india bomb was released because while he may have wanted to, there was never any proof he did.
its pretty fascinating. its not wingnut stuff, its just, which was it?
and as years go by, it leans more to mech failure
and it fits in line with boeing (and airbus) know ALL about the flaws in their planes....
I think it’s been obvious since over the last decade that severe negligence has been injected into aircraft manufacturing and air craft operators
its negligence, but its also a desire to keep a perception of safety
people would be just too scared to fly if they knew everything
MA-370 I personally think really cracked open the can and they (manufacturers and operators) haven’t been able to close it since.
i dont remember what mh370 was. i thought they said it was pilot induced
never found it
MA-370 is the flight that went missing in 2014 for no apparent reason
No black box or anything found except some seats that might have been from the flight washing up on a beach
oooh, they think it was decompression
yeah
yeah, never any conclusive answer, mechanical or otherwise
so i wont name anything. but there was a plane that went up, caught fire, came down, went to hanger, sat there 3 months. never reworked in the burned section. one day, back in the air. no new, passengers never knew anything, nothing.
was the plane safe? i guess yes? would anyone fly it if they knew what happened? no
Ah Great American Airlines? Lol
i used to go on the air india 747-200 2 times a week or so. the plane was often held for several days at the airport while they were forced to make repairs, at least once it was the door.
Lol
their security was pretty lax. one guy on there, usually sleeping
(in fairness, most aicraft have no security at all)
Well, not after you get inside the perimeter anyway
royal jordanian being an exception. hit the runway. 4 guys with machine guns go out to the corners, walk it in to the gate and STAY there. then walk it back out 3-4 hours later
we werent allowed on the plane either.
we put everything next to it. and the guards took it
Oh wow
yes, they dont mess around
after 911 security overall went way up
before that though it was incredibly lax
Yeah, I used to see my grandma to the gate and then after 9/11 stopped at security
(withing the secure zone)
Now only parents/guardians of minors or people helping those with disability get through temporarily
yes, domestic flights here are still kinda lax. internation is beefed up
Our domestic flight security is a pain
bah
Large international airports here it can take hours to get through security
weve not had many incidents here. the air india was the big one, ad it may well have not been an incident anyway
i never got to go on the concorde :/
That would have been fun
it came saturdays and i had that day off
I never lived close enough or had a reason to fly
well i wouldnt have flown on it. just did work in it. (loading food and other things)
we did have a uae short 747 customer. they went to a private hanger
cute plane
Oh gotcha, before your vfx days
That makes sense
but even then, pretty nil security. (other than private hangar)
royal jordanian was not even diplomatic. just passenger flights
I’d love to fly more
But the cost to go anywhere just sucks any possibility away
$117k doesn’t go far these days with the cost of housing, food, and unfortunately student debt 🥲
yeah. i used to fly for $80
I can just afford what I have which includes 2 cars so my wife can take the kids to school if I have to go to the office early
and air canada family discounds are clamped down (my cousin flies an a320)
But my parents didn’t make enough for us to fly anywhere so it didn’t really get used
We were a road trip family because at the time, hotels and gas were cheaper than flying 7 people
they had their own plane for a while. not sure if he still has it
a little. uh... not Cessna. i forget.
soemthign small
ha
Gulf stream?
hahaha no
There are some cheap gulf streams
i had a friend who's mom was in charge of deliveries for the global express
Used market for gulf streams is pretty decent
she said that most planes left with at least 2000lbs of gold
Lol
(trims, decorations, plating etc)
Yeah, there is a surprising amount of gold that is in the air at any given time
a lot a middle eastern customers that like gold
but also americans
like trump. his plane has a lot of gold in it
he bought it from paul allen from MS
(i did a discovery doc on it ha)\
757
the russian antonov planes are neat to be in
they are mostly made of duct tape near as i can tell
haha
oh man
ok, so, ive been on some old planes (60s) and new ones (a340, 777), and OLD... and NEW planes are built pretty smartly.
but there was a time in the middle they did some super dumb things design wise
767 and l1011 have powered doors.
soo coool and futuristic
but its on the ground and not turned on, how do i get in?
l1011 has catering kitchen in the belly with a cute elevator. so nice, out of the way. oh, right, its on the ground and the power is off!
747 has an elevator too, but it also has stairs
l1011 has super nice precision slots for all the catering with latches that hold them all snug.... except its 40 years old and i dropped the box and nothgign fits now!
sigh
heheheh
lots of other things like drink boxes 7 ft up, where its almost impossible to lift them to
designed by engineers that never set foot on a plane let alone worked on one
Generally how it goes
Same with vehicles
yeah
Cool design, except I can’t remove the oil filter without taking off the front right strut
Or replace the battery without removing the front headlight
ugh
Or like on the HHR, the battery was all the way in the back of the car
a lot of people try to make that a conspiracy (and maybe some is) but often its just cramming things in like a puzzle. "this what you git"
c3corvette was in the back under the seat. took my friend a full 10 mins to get at it to disconnect while his engine was somehow stuck on full throttle
One place I lived, someone has a C4 or a C5 that the horn just blared for a day and a half until the battery died
It was quite annoying but it happened over the weekend so nothing got done for whatever reason
ha. i think that was also going at the same time. i dont remember what was wrong, but the car was "gone" for months.
Corvettes are cool but I’ve heard when they need maintenance, they.. need it
