Is wifi in built?
Would I have to get a wifi chip?
Wait no it doesn't
Well to some up my desires
- I want to create a wifi prenk machine
- I don't want to overwhelm myself with insane codes
The pico would need a separate chip or module.
Complicated is relative, so I'm going to avoid giving a numerical answer.
https://learn.adafruit.com/adafruit-qt-py-esp32-s2/circuitpython-internet-test would be an example of an ESP32-S2 using its WiFi functions to get some basic data off the internet?
If I got it and had queries would you be able to help? I'm not necessarily asking for spoon feeding, I just feel like I might have trouble getting far
Looks a bit more involved, but there are likely other examples you can derive code from for your needs.
Hmmm okay
Maybe not myself necessarily, but #help-with-circuitpython is always open for those kinds of questions.
Oh, you can use Arduino on this as well, if you want.
Probably will stick with circuit python for now
Good god
the amount of adapters imma have to get for these mfs
usbc moment
I don't have USB-C on my PCs. Lol
Thank you so much for this advice I would be lost without it
I will order one then :))
am I trippin
Or does that say $47.80
Would this be ok?
That one would need a matching uFL antenna to work, but you should be able to find one locally somewhere.
Realistically, any ESP32-S2 board should work. If the Adafruit boards are hard to get in Australia, You should be able to pick up an ESP32-S2 board from AliExpress instead. https://www.aliexpress.com/item/1005003145192016.html

Man, that's a long time
might smell like burned electronics near my computer but I cant locate where it comes from...
there’s an electronics store near me, would i find it there?
Possibly? I don’t think it’s likely but I’ve been surprised before.
hmm
theres this
nope that doesn’t look like what i’m looking for
I’ll order the one off aliexpress
I'm keeping my eyes out for another Pi Zero 2W.
Is there an example of how I could run a command with this board over wifi?
I guess my question is is there a way to connect it to a wireless usb adapter like this
Maximum wireless transmission rates are the physical rates derived from IEEE Standard 802.11 specifications. Range and coverage specifications are based upon test results under normal usage conditions. Actual wireless transmission rate and will vary as a result of environmental factors, including...
Same code as any other esp32-s2 board. https://learn.adafruit.com/adafruit-esp32-s2-feather/adafruit-io-send-and-receive-data
I don’t know where the direct tcp example is, but I know that exists too.
Thanks, appreciated
I think before I buy it I should at least do some more stuff with my pico first
does anybody know if raspberry pies are cheaper?
Raspberry Pies are probably cheaper than Raspberry Pis 😉
In all seriousness, check reputable sellers often, sign up for alerts, and enable 2FA if they require it (Adafruit does) so that when you get the email you can jump and order as quick as possible without anything else being in the way
ok thanks
oh hey, Jaycar, are you Aussie?
Yeah, Melb :))
Oh nice, same!
does anyone know the name of the pushers for these types of syringes?
it’s a nice city :))
yeah
Thinking of a new Project Idea:
-An application that opens with a black screen with an eye in the centre
-Using boards and receptors to make the eye stare at something depending on the orientation
the objects around it
eg. you walk past holding the object and the eyeball follows it
Not sure what hardware I could use to make this work however
Typically, you'd use a camera.
Shape recognition and tracking would all be done in software.
Like.. heat? lol
Yeah, you can do that with a variety of sensors
I think I would opt for that
Ahhhhh I feel so overwhelmed with what to get I don't know how
The first part is figuring out what the goal is.. and the best parts to use to achieve that.
For every option, write down the pros and cons.
First I need to draw the eye
All the elements
Should be the easiest part
Then I'll need to look at purchasing a sensor that either connects to my computer... or I think a microcontroller? might be wrong tho
That's what your research period is for. 😉
hmmm
Take a look at this
4m range, not sure how it measures distance tho
Ping.
Like solder paste dispensers? "pistons"?
The VL53L1X uses a VCSEL (Vertical Cavity Surface Emitting Laser) to emit an Infrared laser to time the reflection to the target.
So, pew goes ping.
not one of those lazers
i'm not that dumb
i think
I mean as in will the laser just keep going until it hits an object?
Yes.
What about a laser that tracks the distance to something emitting a matching signal?
It's a straight-line measure of distance, via timed response.
Ahh ok
Field of view isn't great tho
15-27
Would be looking for 180
x_x
this shtuff aint cheap
What about this
Still looks like it's doing the same thing
Usually a smaller field of view is better for accurate distance measurements, and a servo or similar motor is used to scan a wider area with multiple measurements.
Also a good option, should offer better distance range options and function similarly at a high level.
When you move around with an object
Oh, then a camera with facial recognition might be better suited to this. Not sure what a good device for that would be with the pi pico…
Pixy2?
Pretty much sums up what I want to do
This stuff is scary
I don't know how much it will cost
or how much code will be required
and what level the code is
This is incredible btw
What servo did you use?
Pretty much any servos will do, I think those were SG90s
Thanks
stupid me, had an eye problem with the left side eye for a week. Was about to get a doctor appointment then I fgured the powerful table fan 2 feet away from me was causing it 🤣
my eye has been fine since then
like eye was painful and I saw blurry and couldn't figure why
Since then, not a fan fan.
i have discovered slackware
When not running BSD of one flavour or another, I would usually run Ubuntu or CentOS, but I just installed RHEL 8, I'll see how I like it.
new space mission boen starliner
#Starliner is preparing for liftoff! At 6:54 p.m. EDT (22:54 UTC) on Thursday, May 19, Boeing's spacecraft launches aboard a United Launch Alliance Atlas V rocket on a demonstration flight that gets it one step closer to certification to carry astronauts to and from the International Space Station.
The Orbital Flight Test-2 (OFT) launch is from...
I wanna get my old XP laptop online but I don't know how
I can't use Ethernet because I'm on the other side of the house
On the one hand, Ethernet can easily go that far (you just need a nice spool of CAT5 or better), on the other hand, there are WiFi to wired adapters if the WiFi gets that far.
Or powerline
I tried a USB Wi-Fi adapter but it's not working out of the box, so I might need to predownload the drivers or smth
Does anyone else kind of jump project to project like its a shiny new thing? Im just starting software development on one where ive designed the hardware but I find myself wanting to start design on another project at the same time.
I dont know if its because of the FOMO thought process, especially with parts being harder to order or if its a mental issue. Or maybe Carpe diem
Probably not a "mental issue" but I kinda understand the feeling. As more of a hardware guy than a software guy, it's fun to get shiny new hardware, but then I have to write code and that takes way more effort than soldering a couple of wires...
Personally, I blame a couple of other things as well, like the lack of large blocks of spare time to focus on one thing, and not being able to run my 3D printer due to lack of noise isolation...
But definitely not abnormal in any way. It's just another hurdle to overcome slowly.
I know what you are getting at without saying it 🙂
In that regards, yea, same
Almost all of my tinkering has stopped at a proof-of-concept stage, and the one that got a bit further has been superceded by a shiny new device...
Hopefully once my sister-in-law finishes her exams, I'll be able to start running full-length print jobs again...
One project stopped there. I designed it all in CAD and finally went "Ya know, maybe I dont really want to build this, I just want to build something useful rather than an item thats gonna sit on my shelf"
DIY is hard for a utilitarian.
I had to spend years of saving money and working through self-loathing to get over myself and build something just for the fun of it.
Because really, building little steam engines are nice and all but they end up just being models or sittin my shelf 😐 So I proposed building a tool: Another lathe. Funny thing is, I had to go and make my current lathe really accurate in order to to build a newer lathe. So Now I have a very accurate import lathe..
To an extent. Ive built a DIY coffee grinder that works pretty well and gives a good grind. Best part is:
- I didnt buy anything, other than the native parts. So, what i mean is, I produced it with my own labor, rather than using my buying power. 😉
- I can self repair if it breaks.
#2 is a HUGE point for me. Im not locked behind some plastic wall of garbage.
if you'eve tried to repair something, or even take apart something, you probably know what I mean by that
❤️ My ThinkPad ❤️
My membership application for the OSS society finally went through, hopefully now I'll be able to find the information I seek. I have a plan if I can actually find the info.
if i can find the radio transcripts im going to make a bot to tweet them out 78 years later to the exact date and time which means i have until august to find them
I made a circuit for a regulated soldering iron (this is just to mod my existing one), will this work?
The latter could potentially work, assuming your new DC supply can drive enough current for your heater. If the original is running right off of 110/220VAC, a typical 5-24VDC isn't going to get hot enough...
〔...change of plans, I might be interested in what the "BSD's" have to offer.〕
〔Specifically, FreeBSD and GhostBSD.〕
〔I can edit things and permissions from the Terminal. I CAN EDIT THINGS FROM THE TERMINAL.〕
I was going to rectify the wall power
Aha, the Pleco Chinese dictionary app uses those brackets
in brackets is the traditional character corresponding to that first simplified character
Oh, then you'll need an op-amp and transistor rated for that voltage range. Transistor isn't so bad, but the amplifier is not going to be as easy to source...
Oh I was just planning on using a massive resistor here for a big voltage drop. Op-amps have fairly high impedance, right?
Another interesting thing I did not know about them. Cool!
I can't speak for the voltage source part of the Op-amp, as the high-impedance generally refers to the +/- terminals ideally having infinite impedance. If you are trying to avoid using a DC/DC converter, I would at least use a voltage divider for a more controlled voltage...
Yeah that makes sense
Actually, looking at it, the resistance of the heater actually makes it’s own voltage divider
I designed a pretty neat circuit
Although once it turns off idk how it would work
Ed is your friend. Ed is the standard UNIX Editor. I always recommend anyone going into any advanced use of UNIX related systems make friends with Ed. I'm surprised at the number of times knowing ed has gotten me out of some hole I accidentally dug on a UNIXish system.
No, I think your heater runs in parallel with the rest of the circuit.
Also, bear in mind you may have to compensate for the thermocouple junctions. I would suggest using a prebuilt analog amplifier like the AD9495, but they're all out...
What do you mean by that?
Ok, very basic question. Paint often comes in cans, and the fumes are not good to inhale. If you open a can and don't use the whole thing immediately, what do they expect you to do with it? Why don't they put it in a container that can actually close?
and aside from what "they expect," what is a good way to re-close and store an opened can of paint?
use a mallet; that works fine to close it
My dad told me to always put a cloth over before hitting it incase there is any wet paint on it, it wont fly around
nice, thanks all
internet on this laptop is... difficult
Today I'm going to try to control Furby with a flipper zero and with a raspberry pi zero w/ir transmitter. I copied the codes from the pi to flipper so if flipper works then the pi should work. If the pi works then I am going to integrate it with home assistant via mqtt so that Furby can be controlled from the UI, scripts, automations and voice commands. We have a Furby in original packaging so the plan would be to hide the transmitter in the packaging so that you don't see it.
ok winter has claimed my last cup of coffee
suggestions on making a safe heating pad ?
Radio Snack used to sell some immersion heaters that clipped onto a mug. Those warmed the contents instead of the mug. When the local one closed, I showed up with a station wagon and some cash and bought out all their carded stock and a random lot of other stuff, including several of the aforementioned beverage warmers. I still have most of them.
What's the right diameter for a coaster?
I got Flipper working with Furby by copying IR codes from a pi/transmitter. The pi/transmitter does not activate Furby when I send the commands so I'm going to use an IR receiver to make a new remote and copy the codes from Flipper and see if that works. I need the pi transmitter working for home assistant integration. I was given a semi broken (silent) Furby to take home and play with. Turns out it's not silent lol
Big enough for the cup/glass.
Does anyone know how, or if it's even possible, to take a shape like this in Inkscape and get out JUST the outer edge?
Like really bad edge detection essentially
I need to make a list of parts for my Pi Keeb mod. 😁
I think I need to build some form of dock, so the Pi can connect to the keyboard and have a full-size HDMI port.
9.5cm or so is common
A couple of custom-coaster logo sites use 4" or 3.75", it looks like.
That would be a little small for the mugs I drink out of, but you may be targeting more human-sized drinkware.
1st hurricane in my life 😦
I'm not even joking never seen weather so bad in my life and hurricanes never happens here. Just saw a oak chair fly off from a balcony above me and hit a truck
Winds must be like 70-80mph
Hey be safe
I remember when I was a kid I built a windmill, and the wind would turn it but it wouldn't generate any electricity. One day, it was really windy out, so I took out my windmill and it was spinning really well and starting to actually generate electricity, but then, one by one, the blades started to bend back. Then my mom came out asking what I was doing outside in a hurricane. Oops.
That's mildly terrifying
yeah and we never have such things here so probably someone in the tornado/hurricane alley would be unimpressed but when I saw it at its peak (when I wrote) I was kinda scared
it did some damage in the rest of canada like breaking apart a turn, uprooting big trees, flipping planes over and a couple of deaths
I managed to get Furby working with home assistant with an esp8266 + esphome + transmitter. Idk why the pi didn't work but I made that fact irrelevant. At first it didn't work with the esp, so I made the signal repeat a few times which made it slightly better, ended up making it repeat 20x and now it's reliable.
set up a minecraft server for my wife and I
Note: Never underestimate an ancient laptop that is stitched together with miscellaneous parts and electrical tape.
or the flexibility of cardboard, especially covered with duck tape and aluminium foil
also aluminium foil make great faraday cages, rf blockers, infrared/flir blocker and aircraft radar blockers(PESA/AESA)
oh god this channel
True.
Oh! Update on the Void Linux situation: First-time install was a little rocky. Ended up setting the user password to something other than the root password, and network issues were a constant. I will have to try again when I next wake up, considering that it is now past midnight.
what's wrong? 😦
dw its uhhh probably fine
how do you understand if something will work, besides getting a real life sample?
I mean there are electronics simulators, but aren't they limited to circuit analysis?
Three things, basically. The first is experience: after building a bunch of circuits, you get a feel for what's likely to work and what isn't, and ways to address likely problems; one nice thing is you can borrow other peoples' experience and learn from that. The second is understanding: it's related to experience but is more concrete, knowing the actual behavior of various components and circuit elements in a variety of situations and how ideal performance differs from real world performance. The third is "divide and conquer": instead of trying to get an entire complicated circuit to work at once, build and test it a section at a time; to make sure the individual modules are robust, to get better understanding of how they work and respond to conditions, and to identify useful probe points for debugging and analysis. Then when you put them together, you're in a better position to get them all working smoothly together.
also another dumb question
what do I need complex numbers/vector notation on ac?
I mean I'm reading this
https://www.allaboutcircuits.com/textbook/alternating-current/chpt-2/polar-rectangular-notation/
but now I'm realizing, that I'm not quite sure of the purpose
While you don't strictly need them, there are lots of ways to think about the leading/lagging phases of waveforms through reactive components (inductors, capacitors, etc.). However, people discovered that if they assign the reactances to complex numbers, the math works out neatly and it's possible to graph/visualize the behavior in two dimensions nicely (by assigning the "real" component to the X axis and the "imaginary" component to the Y axis). Personally, I found that visualizing approach to be a handy mental shortcut, once I got used to it. However, there are other approaches, such as polar coördinates (look up Smith charts for examples), and so forth.
I danced too hard yesterday and sprained my ankle
Anyone want to hazard a guess what I was dancing to?
break dance ?
"Chip Shortage"
Nah it was "Raining Tacos"
🤣
I got just a little too excited moving bouncing my feet back and forth to the beat and something in my left ankle went pop and I immediately knew I messed up
So yeah turn out it was a "land hurricane", because they form on land, they are called a different word and have a different shape and are intense but don't last long but they can form tornadoes along their shape. Typically they are 70-80mph wind speed with gusts of 135mph (that is what topple all these trees/cars/etc)
If I remember correctly the generic term is "cyclone"
Encompasses hurricanes, typhoons, etc.
and this one started in iowa/missisipi/michigan
me neither, but there are solid sources 😄
I'm not doubting I'm learning 😉
yeah I know, I was doubting it myself, was checking if it was too sensationalistic to call it my "first hurricane"
but since NOAA itself call it a land hurricane I guess I'm fine
Technically hurricanes are cyclones above a certain wind speed which form above the Atlantic Ocean so it's more accurate to call a derecho a "land cyclone" than a "land hurricane"
But it's still hurricane speeds
Also there might be another one today in my area 😦 🪦 🌪️

the odds are low, I'm in the yellow area, but yesterday I was in the orange area and we still had one
Although technically I think tornados also fall under the same classification of "cyclone" so that could be confusing
Why can't we just have one term to classify large wind speed cyclones that doesn't depend on where it forms?
I guess it's because they have some unique characteristic, I mean hurricane dissipate. But derecho don't, they can start again of the same conditions stays
Technically a typhoon and a hurricane are exactly the same but a typhoon is in the pacific
I vaguely remember hurricanes are more rotary and derechos are more linear.
yeah
Okay if there's a qualitative difference in wind patterns a different word makes sense
and I mean....
But for the typhoon / hurricane example it's just silly
Japan has existed for millenias, not the US
so Typhoon is the more correct word
which was invented a millenia ago
we are the one that had to invent a new word I guess, right ?
I'm not saying which is correct I'm saying just freaking pick one
If you're going to get picky about words, "millennia" is the plural and "millennium" is singular (and "millenias" makes me twitch) 🙂
If we're going to use the word hurricane in English it should apply any time we are talking about one regardless of where it is. If not let's use typhoon for all of them.
I agree, but we have like 10 words to describe beautiful in English. Seems meteorologists like to do the same to describe storms 🤣
Yes but at least the different words for beauty have nuance
Rather than just a different word for the same thing
That's the beauty (and the pain) of English: it provides a welter of subtly-different words for things (and sometimes the same word for different things, let alone things like homonyms).
Really though you're only reducing the possible things you could be saying by half when you use a different word for each. If you want to be specific about where it's taking place you necessarily already have to provide that extra information that encompasses the fact its in the pacific or atlantic
And some words ("oxygen" for example) contain in their roots some basic misconceptions.
So it does nothing useful to have different words for where the storm is
Specificity is nice, but it only works if everyone agrees on semantics. 😕
oof don't get me started on why connecting planes of water have to have different names...
There are a host of poets that would take issue with "nothing useful" 🙂
and how if you consider space our ocean are basically a big lake delimited by space
At best it can be used to give a vague location in a story without having to specify exactly where.
Lake? Pond? Sea? River? Wadi? Wash? Gully?
So not useless just nearly
Oh no I'm saying
Typhoon versus hurricane
One is in the Atlantic one is in the pacific
well I have more issue with the big earth ocean getting different names
And that's the only difference between the two
when it's connected
I'm glad the term "typhoon" is still in use, as it allows humour based on similar soundalike terms like "Oh, he was a big movie typhoon!"
If you're specifying where the storm is already, then using a different word for which ocean it's in is redundant
arctic is especially silly as it is basically the north atlantic ocean with ice cubes
It also makes "Ty-Phoo" tea a slightly less random appellation.
And conversely because the classification allows such a wide range of locations, you can only give a vague sense of the location by using the nuanced differences
"Arctic" comes from roots meaning "land of bears"
but it's not even land ?
Or maybe not: https://boingboing.net/2021/01/20/how-the-etymology-of-arctic-complicates-the-cryptic-etymology-of-bear.html
That would be like calling a frozen lake a different name when it's frozen
I mean I can understand calling bay a specific name or detroits etc
Or calling dark orange "brown". Oh ... wait. We do that.
It would be more like naming a floating ice island in the middle of a lake that never fully melts
but the atlantic ocean is connected everywhere on earth, there is no reason to change it's name to pacific or indian ocean (but I know north sea or carribean or mediterreanean have completely different water characteristics so these I'm not as irritated over it)
Okay so I don't take issue with the fact there are different names for different sections of water
Same thing applies to arbitrarily formed state borders
I do with as much issues as you take with the different names of kind of tornados 😄
There's a great animation of the state boundaries changing over time
I mean if there was an underwater nation of intelligent fishes I would be fine with it
Yes my point is that naming an area because it's a commonly frequented place for a particular context makes sense. Naming something for the name associated with that context is what I find silly
But I mean it's not the first time I disagree with international convention/laws
Like my friend who named her cat "Eponymous"?
I still recognize Pluto as a planet for instance
I didn't sign the treaty giving authority to the international astronomical union so I don't see how I'm bound by their decisions
Can't give an exception to one thing and not apply it to others, lest ye be inconsistent
An astronomy teacher asked his class to vote on the planetary status of Pluto. They voted for it to be a planet. Then he pointed out there were more people in that class than in the International Astronomical Union.
And Persephone?
See, I think anything that can pull itself into a sphere should be considered a planet
Including spherical moons
The initial draft of the new rules for being a planet happened to exclude Earth. Ooooops.
I'm with you, I mean give it "classes" like star trek if it make you feel better
But I wince when someone say our solar system is hopeless and there are no habitable planets
no, but we certainly have a lot of interesting moons/asteroids...
You want to see scientists spun up over things? Ask them to agree on a definition of "species"...
Nah I already have physicists angry at me in my area don't want another body of scientists 🤣
One mailing list had a big argument over whether blue light could influence the ionization voltage of a gas. One group insisted blue light was non-ionizing radiation and it was impossible. Another group said it was possible. I was a member of the latter group, and stood by my assertion, as I (and a host of the others) had actually done the experiment!
I think in the satr trek classification they o something like Sol III for earth and Sol IIIa for the moon right ?
yeah that is the issue I often clash over with the local physicists. Until they've done an experiment it's not science, just "beliefs"
And they lose credibility when they talk about fringe physics as facts when the only proof is mathematic (which is a lot like statistics, you can make it say whatever you want)
Their argument gradually weakened to "but you can't explain why that happens", which I cheerfully agreed to (I had hypotheses, but hadn't figured out a way to test any of them). But I pointed out there's a world of difference between "that's impossible" and "I can't explain why that happens". One of my favorite Asimov quotes goes something like "Breakthroughs in science are less often accompanied by "Eureka!" than by "That's funny...""
An astronomer was teaching the intro the physics course in college to me and gave me zero on an exam question (on wheter if was possible to catch a cup that fell if you don't see it fall)
I said it was, she said it wasn't. Couple of minutes later she knocked out her cup of coffee behind my back while I was at the desk discussing with her with other students (I didn't see it but heard it) and I caught it mid-air with the catch-in-by-the-handle and put the other hand on the other side about an inch lower to make up for the angular velocity of the rotation around the handle) and didn't even spill a droplet
She still didn't want to admit it was possible. So I brought up that event when she met with a coworker/friend that taught another group in the same class and peer pressure gave me my 4 points back. 🤣
I have several little brothers and sisters and that happened a lot when they were babies/toddlers so I had training
It's kinda hard to explain to someone who never had kids/didn't babysit but you become "cup-location-aware" and wheter they are likely to spill on the floor depending on how close they are to the edge
I have to ensure my tea is out of bunny reach... 🤣
I made cardboard panels to cover the empty space between my counter and desk and bought cup holders for cars and hot glued them to the cardboard boxes of my panels
Hehe
Can have up to two beverages next to my computer within arms reach
Thankfully, the bunnies don't climb much.
They can get on the window sill and couch.
Will eventually replace it with wood but more the time being 3-ply cardboard boxes with duck tapes is sufficient
oh I thought you meant like caged bunnies so they don't get wet from a spill
No, no.. little Madam enjoys tea, but caffeine not safe for bunnies.
You could just add a former bunny cage around the cup holders 😄
Lol
But then you'd have to use wood to screws in the 90o brackets to hold the wire cages
Yeah, somewhat overkill for a little coffee table. 😅
Yeah or use those baby cups with the 5 holes on top
pretty sure bunnies haven't figured out how to unscrew those in 2022 😄
plus if the tea has particles that got throught the bag those will filter it out
I'm going to buy some herbal/fruit teas tomorrow.
I mean those
then you you can use some vinyl you stick on to make them look less babyish with flames stickers etc 🤣
1st thing I think off when somebody say they need to buy wheat seeds
I once tried to budget for a fictional farm, and just the wheat seeeds was very complicated
I though it would be like buggle gum in the 1990s, but not thousands of choices
and most of them you are not allowed to take the seeds in and replant
also only 1 company mostly
Yeah, you need non-GM.
since then I can't understand how a farmer can make any money with wheat when the seeds/fertilizer/side products costs like half of the price of wheat per ton and they need to pay the 350000$ harvester and 275000$ tractor
Problem is... When it comes to farming quantities.. it turns into legalised monopolies.
Didn't mention GM because I didn't want to start a political debate as per the rules. But I would think that would cost even more
I get you
I think the word for the ones you can replant is heritage wheat seeds
Yarp
Couldn't be a farmer anyway, besides the price issues and even being able to get a 700k$ business loan to start one, is that I run away in terror when I see a flying bug
Like I don't take the time to ID it because that give me 2-3s buffer to run from it if it turns out to be a wasp/bee/hornet
they are paid a fixed rate by the gov
they even overproduce stuff, but that goes to waste for being able to keep up with prices...
I see. I thought they would sell for low rates on the chicago mercantile exchange or something
I did my business plan financials when wheat for 365$ a ton on the cmex (chicago mercantile exchange) and the raw materials to make it were 215$ for the cheapest stuff
not including all the tools needed, the tractors, interest on the land etc etc etc
super annoying in the evening there is a dog who barks, in the morning seagulls, then do start the super annoying pidgeons with their huhum, then screaming kids...
And at the end if you are lucky the average final profit is about 20-80k$/year for a small farm
Wonder if that'll be hard. We're supposedly coming up on a global wheat shortage
so if you have a better job it's not worth the risk
Well when you see shortage, keep in mind all countries grow different species. Some species are for eating, some species are for animals to eat etc
Found loads available online.
Non-GM, so.. good for the bunnies.
so a wheat shortage doesn't necessarily mean that all use of wheat is in shortage
I only want grass, so I won't be producing wheat seeds for processing.
Also canada/US main agricultural product is wheat, so not really a big problem in north america
idk the ban of gm to me does look only like a protection measere to some business
I might be wrong tho
If there is problem canada/US will just make starting a farm more attractive to potential new farmers (like me) to throw money at the problem
and asks peoples to mainly grow wheat
That solves the problem potentially one harvest from now at the soonest.
eh I see it would be more probable to abilitate current business to get more lands
the gov does also profique by monopolies
In Canada I could start a farm tomorrow, 95% guarented federal 500000$ loan so my maximum liability is 25k$ (and a bunch of criteria like they can decide your location within a province)
Bad things can happen between harvests
If there was a problem with wheat they could adapt the program to be 1m$ 100% for instance but 50% of the production has to be wheat and you have to show you have the training to start planting tomorrow
really?
don't they request any sort of security item/cash?
they are guaranteed loan, so the qualification is the criteria of the program
student loan are also guaranteed in most of canada
so that 18yo with no credit history or bad credit etc can get them
alright I'll get a ticket to canada then lol
guaranteed in Canada mean that the federal govt pay the interest if you can't pay and keep the difference between selling all the business stuff and the owed capital
the other big criteria is that there is a qualification exam to prove you have minimal qualification to run a farm, but again that is a 1-2yr course
The other thing they could do is give away crown lands for free since this is usually the biggest expense
an acre of land is 2100$ on average in Canada
don't you have any other bottleneck? like before doing such cert, you also need to do x school and have x certificates?
They have done it for a couple of years now in Yukon. US/Canada did it a lot before 1930 too
They have a standardized course to learn how to run a farm, and technical skills like setuping a tractor etc. Basically vocational course
So their minimum is that you have complete one of the course or something similar in one in the farming course group
ie: they want you to be able to contribute something to the farm to get the loan
wheter it's managing the business side of it, driving the tractors, taking care of the animals, planning the crops etc
I used to think mulcture was a bad idea, but now I'm starting to see the appeal...
as a farmer the other help is that you don't pay taxes on agricultural products/gas
here for everything they do requests decades of specific schooling, then a certification, and then being subscribed to some lobby board that does enable you to do such job
useless to say that the economy is broken
taxes are 60-70% of the price of gas in canada, so that in most place it's 2x the price per gallon than the US
well the US complain every week about that program to the World Trade Organization 🤣
so yeah i'm pretty sure it is good
agricultural product = something that is useful in a farm. So if you buy say a ford SUV for your farm and shovels
you can ask for the taxes you paid on them to be refunded
might be more difficult to prove the link for a ferrari or a yatch though 🤣
waterculture
the agricultural markets also have floor prices for basic goods
like bread, milk etc and controlled stock (the govt will make up the difference if they force you to not sell part of what you grew)
I find insane that they also have a dumbproof website
https://agriculture.canada.ca/en/agricultural-programs-and-services/canadian-agricultural-loans-act-program/step-2-who-eligible
thing that does not happen in Italy
You can even ask for it to grow christmas trees or pay to transfer your parent farms etc
yep, someone told me about it and it seems quite good and generous so that money isn't an issue if someone really want to start farming
as long as some minimal criteria of realism of the plan are met
What I heard from talking to peoples who were doing the vocational training near a store I worked at (where I learned about these loans) is that in effect it's not that easy because machinery costs a lot
And acceptance isn't 100% guaranteed since the program have a maximum budget for it throught canada. If they have to choose they prefer peoples who can supervise the business and hire peoples or those who can repair agricultural machinery
The banks are also going to "negociate" the business plan so they don't have to loan the full 500k$
it's still cheap tho
ie: "why do you need a brand new new holland 300hp tractor, can't you buy used" etc ?
and those fees have to paid ahead of time and the bank have to make sure you will be able to provide the 25k$ personally if everything fail
But I don't see that as a big barrier of entry if it's something you really want to do
it's similar to what you'll be on the hook for for college in ontario
also if you don't have good credit you won't have the option to personally guarantee renting agricultural machinery which will remove the option of renting them
the land looks pretty expensive though
I need to buy some parts for this tomorrow..
To finish the topic, I don't know about other places, but for a cheap business loan (ie: under 1m$) most canadian banks care much more about the realism of the business plan and the income to repay the loan over time than the credit of the future owner of the business
I mean the first thing they told me is the stuff that are bought are owned by the company, and as an owner I'm the person who is supposed to make the upmost to make it work/represent it. But they reserve the rights to change the owner or close the company to repay themselves if the business plan isn't followed
And they expect the future owner to contribute a token of material contribution (cash/equipment) to show they believe in it too (so they aren't the only ones taking the risk)
That attitude surprised me a bit, but clearly not the same as a personal loan
I mean at the base a business that just started has no credit
And the loan is to the business, not to the owner
is that something you are repairing ?
Nah.
Installing a Pi Zero 2W into a keyboard. 😁
There's not enough space for a Pi4, so.. ehh
is the pi 4 computer thing good ?
Yarp
from what I can gather the pi 4 is always out of stock because of industrial use, but the pi 4 computer use a consumer version that isn't interesting for industrial use so it's often in stock
I need to get at least one Pi4, but I'll probably go for a 400.
probably me too for my 1cf robot...
I doubt that a pi2+ will be enough for a 1080p camera, flir and lidar
If the Nvidia buyout went through, we'd get an ARM CPU with NVENC.
Yeah stuff like this I why I think my 1cf robot is realist now
Back when I had my robotics course about 15 years ago those bosch robotics sensor were much more expensive
and lowres FLIR started at 6000$, cameras were basically sold for the price of movie studios cameras etc
LIDAR was even worse
all of those are 100$ish now...
Back then I wished I could ever use FLIR in my lifetime, didn't expect it to be affordable so quickly... I mean back then they didn't even sell them to civilians
...i could use some assistance please. this void linux base install is kicking my !@# and I can't seem to connect to the wireless network available to me through wlp2s0. idk if I mis-configured something, or if I am doing something wrong, but I am following these troubleshooting guides for information: https://askubuntu.com/questions/204936/how-to-detect-security-mode-of-wifi-access-point-wep-wpa-wpa2, https://askubuntu.com/questions/75625/how-do-i-scan-for-wireless-access-points, https://wiki.archlinux.org/title/Network_configuration/Wireless, https://linuxcommando.blogspot.com/2013/10/how-to-connect-to-wpawpa2-wifi-network.html, https://www.linux.org/threads/wlan0-unsupported-driver-nl80211.31390/, and I am completely lost.
wpa_supplicant isn't cooperating with me either.
Now, even though it is active, it is not conencting despite the SSID and psk matching in the /etc/wpa_supplicant.conf file.
Wrong driver maybe? [Still trying to figure out how to properly identify what driver my wireless adapter uses with what limited tools and functionality I have, i.e. the iw utility.]
so really basic question, are you connected to here with that wifi connection with another OS ?
Yes, however, this machine uses wlp3s0, though idk if that means that incompatibilities or differences between that and wlp2s0 are present.
also what is the wifi board that you are using ?
on the scraptop or this thing?
I assume you have a newer machine and this isn't an issue that the wifi board doesn't support 5ghz channels and your wifi router is on 5ghz mode only
on the linux machine, is it using a wifi dongle or a wifi card ?
wifi card.
...wlan.
...i think i found the problem.
and to say that i am frustrated by it
would be a total understatement.
well I understand especially on a pi
tried to try windows 10 iot core twice but it never could even find my 2 usb wifi dongles...
while in raspbian my cell phone and wifi router appears right away
probably needed specialized drivers or something...but yeah, that does sound like a pain.
iot core doesn't come with an a GUI OS
so no option to install drivers after flashing it
you'd have to make a custom image... but for once linux was easier than "windows" in that specific use case
and I'd rather go with the easy option
wow.
yeah, same tbh...
I mean I'm here to play with electroncis to take a break from fighting computers all day long
like I'm paid to do 🤣
good idea...I'm taking a break from this.
and hopefully save money from making feature-equivalent electronic device and repairing electronics myself
saaaaaaame
ie: Instead of buying a 150$ laser thermometer hopefully I can build/3d print/etc one for 75$ with the same features
Y E S .
Because seriously sometimes I see electronics that are less capable than a 1$ sensor sold for 80$...
And I can't stand it anymore when I have the capability to 3d print and do electronics and the circuit is simple
especially when most of the cost is converting mains to say 3.3/5/6/12/24V logic
I have a question: What courses [if any, online or not] did you take for stuff like that? Trying to catch up with what everyone is doing in those departments.
basic electronics in college and basic/intermediate robotics in university (the course was for undergrads with graduate material in it, but only graduates had to answer all the problems in an exam, whereas it would be bonus points for undergraduates)
but it's mostly all those bought I books the experience of the volunteers at my local maker spaces and all my questions here
and having the right tools like fritzing and solidworks
My main problem atm is that I have a wall of theory complexity that is hard to pass and I don't have the capabilities to do some project because I don't know use to use wood tools or solder
this has been my challenge for a while along with knowing the main options for main sensor types
did you mean electronics or knowing linux here ?
USB chargers are cheap to free, so I build a lot of stuff using 5V supplies.
Uuugghhhh..
Night shifts go so slowly. 😐
I meant when you buy a 80$ commercial device the cost isn't the sensor capabilities but safely converting the mains power to a much lower logic voltage
Where as I have an overabundant supply of NiCD AA batteries and I'd rather pay for sensor capabilities than the convenience of mains
both.
So I don't see myself buying a 80$ methane detector when I could do it for 20-30$ with a better sensor..
Needs moar 18650s, obviously... 😁
When there are 3 things that scare me a lot:
- Flying predatory bugs(wasps/hornets) 2. Fire 3. Shock
18650s are pretty much number 2 and 3 shudder
I get intimidated when I see 250A on a rc scale motor...
People are shocked when they find out I'm not a good electrician...
I don't. 😁
Even if nobody gets hurt (which would be criminal negligence)
I only mess around with low voltage DC.
They can fine you up to 100000$ for doing electricity work without an electrician license (that include changing lightbulb and sockets if they feel mean)
plus up to 500000$ for each violation of the building code/electrical work annex
- your home insurance would be in breach of contract
And if you fail to understand and do it again they can jail someone for 2 years
I'd have taken courses for it but the problem is that master electrician == starting a business
Yeah, it would be hard around here anyway since the tools/protective equipment isn't basically on free sale
Thankfully, tools are cheap.. and my protection is sense. Lol
When the local industry accept to sell only one they will usually make sure you are competent in the business
That way if some accident happen they can show they took basic safety information to avoid liability. Jurisprudence I think ?
So most companies will only sell you a class 0 certified high voltage gloves with the yearly testing if they think you are proficient in electricity
I mean you could get one in China, but the code ask for ones with a specific certification that China usually doesn't bother to produce
Do you see what I mean? They kinda built a system here to make sure that if you buy serious tools you know what you are doing
Even commercial leasing will usually interview you to make sure you can run say a restaurant if you say it's for a restaurant
Basically for a lease, not knowing what you are doing = bigger risk you will go bankrupt and be unable to pay the rent
Yarp
where as for test/safety equipment = bigger risk they could be held liable
But as I said.. I don't do household electrics.
nah it's just a topic I wanted to talk about you opened the door to 😄
240v AC is a bit too much to mess around with.
In a nearby city they got so annoyed with lottery winners that they decided to make a guide for them of the conditions they'd have to meet to rent industrial space/buy industrial machinery
If I had an unexpected winfall I'd open a shop to repair all kind of stuff and fund my electronics purchase with the repair bill of say a huge spring from a mining truck
I'd like to make bigger machines but everything costs 10x-1000x the cost of the same version in electronics
go ahead engineered, I think you said before you don't like cutting conversations or something ?
I can mono-dialogue for hours so don't mind me 🤣
I just check youtube for 10 hours of relaxing music . I especially like those with a backgound of fire crackling, sea sounds or purring
And listen to a few before I settle on one
roger...thanks.
I like to put on 12hrs+ of nature sounds, for the bunnies. 😁
Frankly when I see a 3d printer that can 3d print strong metal parts out of a variety of powdered metal and laser welding-like that interest me much more than a millionaire bus if I won the lottery
I really need to build a 3D printer..
The metal ones I mean costs above a million thought and are made by the like of siemens, general electric, hitachi etc
I wish something like the sewbot could have been purchased too (3d printer for clothes)
Yay! Got paid!! 👍
CAN SOMEONE PLEASE GIVE ME SOMETHING TO WATCH, PLEASE???
Dang it...
relaxing music you mean ?
the situation has changed.
and the circumstances
i am in great pain
I am annoyed.
Me too I slept for 11 hours without my consent and lost my morning...
Listened to the wrong relaxing music and slept too much 😄
Oof
I got paid, but the only place available for delivery on Uber Eats is a pizza shop.... That doesn't serve pork.
Maybe they have a nice chicken garlic alfredo recipe?
For me it's the opposite, can't tolerate any pork except salami, pepperoni,bacon
You ever have a forehead-first collision with a metal straw after forgetting to stretch before standing up?
...if anyone could shoot me anything funny and/or dumb/funny to watch on youtube, i would greatly appreciate it.
Jimmy Carr.
ty
At least I managed to order hay for the bunnies.. and a heatsink for my Pi Zero 2W.
Ordered this badboi
Hey I would really appreciate it if y'all could provide some ideas on why my port forwarding (for a Minecraft server lol) doesn't want to work
- I can do
telnet localhost 25565on the same machine the server is running on - I can do
telnet 192.168.1.xx 25565from a different machine on the same network when I enable some rules in the firewall on the server computer - However, I can't do
telnet [public ip] 25565no matter what, even on the same server computer.
For some reason the router doesn't like my port forwarding rules. I've also restarted the router to no avail.
I just need some ideas on why I couldn't work
How is the public IP served? Is it tunneled through the router or a separate interface on the host machine or what?
guys
how do you know when to invest in a heat gun?
Roughly at the point where you are trying to juggle two soldering irons at the same time to pull off a %$#(#@ component from a board and it just won't move...
I've personally only used them for rework, but some people also like them for reflowing solder-paste assembly. If you don't do either of those things, it might not be of much use.
i see
what about facing smd pieces?
i swear, using a soldering iron does not help
If you've having trouble with an iron, then hot-air reflow may be something to consider. Even if you don't have a stencil, you can lay down some solder paste manually with a toothpick.
humm
should i just buy a heat gun with its station or would it be better to double down and buy a two in one?
ahahaha
I wouldn't go half measure...
If it's worth spending money, might as well go the whole hog.
lol
yup, that's a sign
I like this gun, but it's super cheap: https://www.sparkfun.com/products/10326
so do you guys think i should buy just a heat gun, heat gun + station, or double down and buy a station that houses both heat gun and soldering iron?
I mean, I found a heat gun and soldering iron for the same price as a heat gun, and the soldering station is the best I've had
Is it possible there’s another router upstream of the router you’re trying to configure? Some modems have routers built in these days…
I've been having port forwarding issues myself
oh heh, same reason too hah
Awful idea: imperial voltage unit, called franklins because AMERICA
There's a difference between a heat gun (large area, lots of heat, useful for desoldering a bunch of stuff at once) and a hot air station (precision area, adjustable heat and airflow, useful for both soldering and desoldering)
alright, hot air station
should i go just a hot air station or double down for a 2 in 1?
That depends on pricing, features, and the amount of room you have on your bench. Since I already had a nice temperature controlled iron, I got a separate hot air station that I just move aside when I'm not using it.
i only have a soldering iron
Depends on what madbodger said basically.
Slowly setting up my new space
Downside of the basement is there are two receptacles for power. Both right next to the electrical box
Easy to run more.
Tis a rental unfortunately
Not sure the company that owns the community would approve lol..
I've asked in the past. Normally individual owners are pretty reasonable, companies are pretty variable (they'll tend to require an electrical inspection of any work, to maintain their insurance coverage).
I had considered asking if they’d run two more drops for me because I want to put more bench space and a Tv downstairs for playing games
I doubt they’ll bite though
I needed to remove adhesive-backed stuff from the walls and didn't have a hair dryer, so I bought a heat gun. It does scorch and melt PVC plastic even on the low setting though, which maybe a hair dryer wouldn't.
Do you ever have one of those days where you humble yourself trying to work on something new? I got frustrated and absconded to the wilderness, usually when I'm out walking I tend to get an idea or two and sometimes I bring my laptop with me so I can work without distractions. This is the view from one of the places I go to.
Magical feeling for sure
There's another spot that I go to where I can see quite a bit of cape cod bay. It's at one of the highest points around here. I'm headed there tomorrow with a couple friends
There isn't much to do around here, My town's Wikipedia page mentions having the oldest house in the area, same for the oldest gristmill and is home to numerous art galleries, as well as rare book and antique stores
Interesting, art is great but the town sounds like a tourist trap for older folks
I love old houses and museums and antique shops though so I guess I’m old
Lol
Lol yea it is exactly what you said.
The whole area is a tourist trap, luckily I found 2 maker groups around here which is great, it's just 20 and 40 min drives in the off season
I finally had a breakthrough with my invention!!
I've created a telepathically controlled air freshener.
It makes scents when you think about it..
...it makes "scents" when you think about it.
...can't tell if that pun was intentional or not.
Very
Lol
what're you up to?
At work
ah
So... Nothing. 😁
ouch.
lol
My job is the IT version of baby-sitting and house-keeping.
i know that one. anything go wrong yet?
Nope.. all good
I would normally say "that's good", but where's the fun in that? Where's the action?
you weren't kidding when you said "babysitting".
This is a minimal activity job.. it's pretty much a Netflix all night role. Lol
cool
I have to say though, even though I am not you or in your position rn, keep an eye out just in case.
Already looking for another job.
No, I meant in regards to making sure nothing goes wrong.
But, now that you bring that up...
What's your plan/what are you looking at for your next one?
Linux SysAdmin.. maybe go back to hosting.
But then, it might be in the US.. not sure yet.
Cool. What does being a Linux SysAdmin entail?
Curious, considering Linux is one of my strengths.
Mostly fix things, ehh? Lol
Depends on the job, the employer, etc.. it varies.. but mostly fix stuff.
Gotcha.
Hello, members of the Adafruit Discord community. We have made a change to the name, and therefore the scope, of this channel. It is now the #general-chat channel. Please try to stay within the scope of the channel and server and keep the discussions general. If you have any questions, please post your question in #help-with-community or post there to ask for a private thread to be created if you’d rather not ask publicly. Thank you.
Welp, this is a sudden change idk what to think of.
...confusion, actually, is one.
May I ask why?
Generally, because we're trying to help folks stay more on topic for the server by making small changes. If you're interested in more detail, I can create a thread to discuss it with you.
Ohh! GITS SAC_2045 season 2 is up on Netflix. 😁
so no more off-topic convos that move away from the main purposes of this server?
That's the eventual idea yes. Our server is meant more for tech-related discussions, and other topics that might not be specifically tech, but are vaguely related in some way (e.g. the earlier discussion about getting away from tech into the wilderness). I did a quick scan over your recent history, and at least recently, you haven't strayed beyond that scope. From my own memory, I don't feel like you have much to be concerned about.
To be clear, unless there is repeated, blatant, and purposeful disregard for what we're trying to do here, there are not likely to be warnings issues initially that would lead to a ban. Our plan here is gentle reminders to help guide folks towards our common goal.
I understand...though I now worry for those who do.
However, if this is the case, then I'm not too worried.
Thank you for your time, and thanks for helping to clear things up for me and anyone else reading this chat. I realize you're potentially busy most of the time, and I might be taking away from anything you were doing prior, so I apologize if I became a nuisance because of this.
There was also a bit of ambiguity with having "general" and "off topic" so changing them to "general tech" and "general chat" helps
You're entirely welcome. Happy to. We'll work together on this change to ensure we adapt as needed and consider everyone involved.
where can we scold people for posting an on-topic message? (kidding)
You are absolutely not a nuisance. I included the comment in the pinned post about posting any questions you might have, and I meant it. Change cannot occur without folks understanding what is expected of them and how. Making sure this change is clear is an important part of what I do, and while of course I have other things to work on, this is equally, if not more, important. No apology needed whatsoever.
In your mind. 😉
can you please become my new manager?
We need more people like you in the world.
😊 I do what I can.
I was following this textbook
https://www.allaboutcircuits.com/textbook/
the problem is that's too argumentative, sometimes it the end there's a recap which I can see, but it's not always present
so in the end I'm googling for other resources while using it as an index, which is timewasting
someone has any other resources?
Wednesday is my first day at my new job as an Embedded Engineer 🤯
Kind of mind blown to be at this point
Going to get to grow a lot more as an engineer
Also excited because I’ve got a bunch of projects I’m going to get back to working on
There are a few messages about other good electronics textbooks here: #general-tech message. Read down a page or two to catch them all
thanks but there's nothing like in a cheat sheet form or websites like programiz/wh3school?
I don't really like books because they do end up into being thousands of pages long, while they could be restricted in few pages...
I wouldn't discount the thousands of pages of theory, practice, and application; this is just my perspective as someone who wishes they wouldn't have spent a lot more time reading those pages while in school.
Tangentially, fwiw, I'd recommend Mozilla's MDN docs for HTML/CSS/etc. In my limited experience, they're better than w3schools (which is in no way affiliated with W3C, and is thus a not-great actor profiteering on their domain name) in ~every way.
I did it...
I bloody did it...
VOID LINUX IS OPERATIONAL AT LAST!!
after several failed attempts...i finally did it...
FROM THE BASE IMAGE ITSELF!!
there ain't no way in !@#$ that I am ready for that.
Hehehehe
congats
That's how it works though. Find a starting place and Google from there; pretty soon you'll remember bits and pieces and jump straight to googling what you need. Another good site I like for this sort of thing is https://www.electronics-tutorials.ws/
Thank you!!
welcome
Now the real fun begins...I have become one with the Void, and nothing can stop me now!!
let's just hope i don't become mad with power here.
AAAAAAAHAHAHAHAHAAH!! HOHOH, HOHAHAHAHAHAH-hacking cough
ahem, anyways...
Finally home and getting settled down. ☺️
How do I find a thread that I was involved in a few weeks ago. It's been archived and I can't find who answered my question and what was in the post.
the problem is that I'm not in school, and I don't have time for all of that
There was a "changing variable names" one toward the end of April?
what is it you want to learn to learn to do? The Make book and the Forrest Mims book are not so onerous
learn how to make circuits in general, I mean if there are online resources, often I can solve X issue by googling, otherwise if the thing is not enough popular, often it takes me too much time to figure out by myself or I have really no idea on how to even start, and often the provided docs is something like huge and I really don't know what to look for
like if for example I want to do a gsm module board from scratch, then what?
if I get an arduino module I can figured it out by googling, but I don't like it
Well, the path to learning isn’t linear and some things require a deepish understanding to achieve. Antenna design requires at least a rudimentary knowledge of RF design. There’s probably videos on it, but usually most people follow data sheets and technical specs for generic antenna design for things like GPS, WiFi, Bluetooth, etc..
are you facile with Ohm's law? Do you know what capacitors and inductors do? Can you use a multimeter with ease?
yes for all
primarily interested only in digital or also analog circuitry?
both
Shoot, I wish there was a cheat sheet for that. Save me two years of grad school for analog/mixed signal circuit design, please.
The Electronics from the Ground Up book and the Charles Platt books are all quite practical. So is the Art of Electronics, but it covers a -lot- of ground, and is probably better after learning stuff in an easier way.
I don't think there's a single cheat sheet to offer EVERYTHING you need to design custom circuits. Often times, the best reference would be the datasheet or manufacturer's webpage for the IC/module you're designing for, as most such products include application circuits that you can often times copy directly into your schematic.
That’s my feeling too.
I probably will get my masters one of these days in VLSI/ASIC design
Oh @dusty citrus this isn't exactly a cheat sheet, but it's a lot of example circuits in a browser-based simulator that could be of interest to you if you're interested in analog circuitry. https://www.falstad.com/circuit/e-index.html
Not a lot of background content or formulas for how they work, but it's interactive enough that you can get some ideas with it.
A really powerful visualization tool for voltage and current it is.
See those I-V curves for caps, inductors, diodes and transistors
offtopic was removed ?!
Well, not removed. It's been renamed to help reorient conversations in the right places.
I NEEDED THIS ALSO. THANK YOU.
good morning btw
I'm stuck with a bunch of espresso shots pods
didn't know that shots are literally 40ml "shot" or "droplets"
My favorite thing to do is think about an email you need to send, word it in your head, and then forget to actually type the email out
I am now a card carrying member of the OSS society. It's pretty cool although I feel a little out of place.
Isn't that the precursor to the CIA?
Yup
I only got in because of a family connection. I am excited about having access to their forums I have some questions I haven't been able to get answers for
All of the answers are way pre internet and were classified for around 40 years so I went mostly from my grandmothers binder she kept, she already had most of the information I got from various archives. I'm either going to find it through the OSS society or I'm never going to find it
Thanks, found those. It was a project that I commented on. May have been a branch? I'll go though my browser history for the GIT Hub link.
So they changed #offtopic to #general-chat ??
Sorry, haven't been able to do much here
I've got a lot of things going. My folks are moving and my job is busy and.....
Don't stress. Breathe...
I get it, life is rough and chaos is everywhere, leaving us to do what we can.
Yep - that's the way of things
But yes, offtopic got changed to general. Hang on, let me see if I can't find that original message.
OK, that's interesting. Does it still function the same??
👍👍
The initial message I posted is pinned in this channel. So you don't have to search for the beginning of our conversation next time. 🙂
roger that, thanks...facepalm
I feel like I'm having a mental overload
Too many variables
too many details
How do I keep myself from breaking down after trying to intake enough information on what Linux component or the next like wayland or how to install window managers on void linux and keep it as fast as I want it to be while potentially avoid Xorg because I'm too familiar with it while...I,Can't,BLOODY!(!^#())'
Step back, take a breath, don't try to do it all in a day or two.
i made a mistake choosing a void linux base image
reason:
i was not prepared for how much research and homework i would have to do just to build the thing.
Ooo, I just found a Reddit thread on the subject. That was probably not wise of me.
ok, first thing's first, I need to figure out how to automatically make this thing connect to the internet via network credentials stored in wpa_supplicant.conf on each reboot, because making it start manually each time is getting annoying.
This is why I just run Ubuntu these days... too many headaches that are best avoided if possible. 😅
Yeah, I'd have no patience with that. I was pleasantly surprised in that regard by a different distro recently.
welp, guess I'm the oddball here, making myself uncomfortable in an effort to learn more about Linux as a whole while working on my first OS base image..after using Ubuntu for ages.
The learning and experience have value, however try to avoid getting too burned out/frustrated in the process. I've been there, and it left a bad taste in my mouth, making it hard for me to return to certain corners of the tech universe.
Ok...roger that.
one thing at a time, engi...
...bloody 'eck, they warned me too.
My friends warned me that this would be tricky, but I did not realize how tricky, nor did I pay heed to their warnings.
this is what i get
You can either slog through it to get to your goal (fast system with a window manager and no Xorg), or change horses and try some other approach.
Well first, ***I need to figure out the BLOODY-***woah, sorry, let me try that again.
First I need to figure out connecting to my Wi-Fi network automatically each bootup.
because right now, I have to tell each program to run and where to go and stuff like that.
...i'm experiencing linux burnout.
That's one of those things that "should" be fairly clean to automate. I seem to remember there are about 4 files to touch, and debugging it takes some skill
I'm having an equivalent problem with a virtual machine, where the network stack is kind of primitive, and has to work with emulated network hardware, that then has to be correctly gatewayed to the real network. I've been poking at it, on and off, for weeks. Until I can get networking up, the only way to load code onto the virtual machine is by typing it in or copy/pasting a page at a time.
which channel should I ask about sourcing a subpart out of one of the third party kits? there's no docs in the kit about the part, and I'd also like to acquire more of them for other projects
I'd go for #help-with-projects or, if you're looking to make a PCB using said part, #help-with-hw-design
ty
Realistically, if you can make a connection to what you're doing, any of the #help-with channels are fine.
go ahead and ask your q
okay sec
//if I have an array of object of some class
SomeClass* o = new SomeClass[1000];
//and I init one element
o[0] = new SomeClass(0,0,0,0);
//do I need to dealocate the memory here before making a new one?
o[0] = new SomeClass(1,1,1,1);```
yes, otherwise you will have a leak
okay thanks
right as you said that
my engine exploded.
im done with linux for the day.
...no i'm not.
Hang on, there has to be something I missed.
or something missing...
What kind of engine? Cox .049?
Hey I think you are wrong about that because I'm trying to delete the object but it says it's not a pointer
still, there has to be something I did wrong.
...wait a minute.
i need some caffeine
brb
new returns a pointer
Ok, you said that you worked with incomplete and/or primitive packages/utilities before, right @late fulcrum ?
I'm beginning to think that the utilities I am currently loaded with are just that: primitive or incomplete.
Like they're missing something.
What exactly I'm going to be finding out here shortly, because if I can utilize whatever tools this thing has for network connectivity and make them automatically loaded each bootup, then what if I can do the same with everything else, albeit with a bit more time spent editing configuration files and whatever else might be interfacing with them?
And what if this entire time, the main reason why nothing auto-loads is because I'm missing something that allows such a thing to happen?
massive duh moment
BRB
Yeah, I've done a fair amount of that, including scripting my own startup utilities from time to time when that seemed like the least painful way forward. While I don't really want to re-invent the wheel, when all the existing wheels seem to be square, I'll give it a go.
Welp, I'm just persistent and wanting to learn more. :P
seems that what I want won't be easily achievable though.
ah well, one step at a time.
I respect that.
The website directed me here to get help with my account but I don't see a tech support channel for anything like that. Any suggestions?
It's unexpected that you'd be directed here, since this Discord doesn't really have account or order support... you'd want to email support@adafruit.com, I believe. Could you link to the directions you followed?

As @crystal ore said, a link to the page that showed you here would be excellent so everyone's on the same, well, page
Ok, so you also asked this in #general-tech - please try to keep it to one channel to avoid confusion.
hi @livid loom the team alerted me (pt here, from adafruit), if this is regarding a raspberry pi order, or account info after purchasing more than the 1 per customer limit support@adafruit.com is where to email
There is a nema L5 20 receptacle with 220V written on it in sharpie, what the heck
I mean NEMA is a mess and l6 looks almost the exact same, it’s just a testament to us needing to overhaul our stupid electrical system
And the fact that we are saying “220” at all is a nightmare
How did those RPIs sell out so fast?
People want them.. ?

New tutorials on the Adafruit Learning System: h...
aka, demand exceeds supply
It gets worse. It’s actually 3 phase. In a 120v outlet. Labeled as being on a 240/220v circuit.
I want to give some positive feedback to DigiKey. I recently placed a hobbyist level order but due to a misleading description I did not receive what I expected. DigiKey went out of their way to make it right covering the shipping cost, twice, and taking an overall loss of over $80. Although the mistake was in the description they honored it and corrected the description. I WILL be ordering from them as much as I can going forward!
I believe three-phase voltage is typically single-phase voltage times sqrt(3)?
Though I don't recall if that's phase to phase or phase to neutral...
Wait, is only one measurement 205?
hey, does anyone know the status of ADABOX? IIRC the last one I received was last year? was ADABOX cancelled? or just another product suffering delays due to the supply-chain in chips?
@orchid zephyr Just to let you know that would be considered a 220V single phase outlet. You might be getting a slightly low reading, 205, across the two hot wires due to the contact of the probes with blades of the outlet. The reading of 118/119 would be the voltage from hot to ground.
I believe the latter? The website has a countdown for one dropping near the end of June, though signups are still closed at this time presumably over concerns with supply constraints.
ty!
One is 205, but two, rather than one one, of the potentials are 120. I assume that it’s off from 208 rather than being off from 240, and that a lead is missing, since there is another 205 potential to the regular outlets to the left
Indeed, it is the latter. The supply-chain shortage is causing issues beyond a lack of chips, which is to say it's not only making it hard to find components, it's also causing a shortage of cycles to put into any one project due to all the cycles going into figuring out how to use what we do have available to make the things we need to make. Adabox isn't cancelled, but it will be delayed.
those two pieces of hardware should be alright no?

I'm sorry for the pics/wall, I can't figure out how to remove them...
Hover over them, should be an x at the upper right which lets you remove embeds.
I'm on monile
Ah fair enough. I'll remove them for you.
thanks
I love Digikey. One time I made an order, realized I forgot a part, made a second order and put in the comments "please ship this with the other box!" And they did!
I don't get to do things like that often because they've usually shipped it by the next day
Their component finding and filters are top notch, too
I have zero doubt about what order from Digikey is legit -- and that's important to me. If I order a $gb memory chip or a part with XYZ configuration, I usually don't prefer or cannot accept a 'close-enough' alternative.
With other major online retailers that use commingled inventory, there's an increasing chance of getting counterfeit parts. Or be shipped used parts that are incorrectly marked as "new". That'll never happen with Digikey.
Digikey's prices are aggressively fair (they're not a discount retailer, but they don't overcharge 'because they can') -- they have top-tier customer support -- and their shipping is fast & packed VERY well (as if the box was going to be drop kicked by the carrier).
Ordering from Digikey removes any doubt, and doubt will cost time and money.
their packaging is sometimes weird though
in the past I got like a 2m plastic wrap for a component with a diameter less than a cm
It's probably one of those standardized boxes that really only make sense when factoring in bulk shipments of products.
When you ship that much product, you probably get better rates than the average person with fewer restrictions.
on the other hand, its great paper wrap to reuse or to give to someone who does ship stuff out.
I love their paper packaging.
i think that what sets digikey above the rest is that they are an industrial supplier first and foremost, and they open that service up to hobbyists, and interact with the same level of precision that an industrial consumer would expect, even when interacting with hobbyists.
It's a great way to do business. Many hobbyists end up later (or simultaneously) designing industrial gear, and that's a good way to get more industrial buyers.
mouser also kind of does that, but i think that digikey does it better.
mouser is the mcmaster carr to digikey's grainger, the sam's club to its costco
(at least thats how i see it, i still use mouser fairly often for BOMs)
I have a suspicion that digikey forced a marketplace seller to take a 500 dollar return from me that they didn't want to take.
My only issue with DK is the existence of marketplace tho. I think it's bad business but they don't pay me to think about these things
yeah i feel like mouser has backordering and distribution more figured out
you work for dk?
I usually uncheck the "marketplace" box, but it's been useful to me in a few circumstances for particular oddball parts I wanted.
No I meant specifically that I don't haha
Misleading phrasing
I just think it has more harm potential than I'd tolerate personally
If it were my business and my customers
ah
I can see their point of view. Most of their customers know that they're just acting as a clearinghouse for the marketplace sellers, and it lets them offer a wider product line without having to stock all those low-runner items. For me, it offers one-stop shopping for some fairly bizarre combinations of items (I do have to pay separate shipping, but it's worth it to get those parts without having to deal with dozens of small sellers that often don't want to deal with me otherwise).
I can see its value, I just think it's a net negative, personally.
i am allergic to spending money, so I only purpose order components, which winds up costing me more due to having nothing on hand
I, on the other hand, love having stuff to hand
The conversation made me curious, so I pulled up all my DigiKey Marketplace orders for the past 3 years or so. A specific toggle switch to repair some scientific equipment, some triple insulated solderable magnet wire for winding custom transformers, some high voltage hook-up wire, some obscure JFETs to replace components in a 50-year-old electronics learning set, and some DIP-packaged FRAM chips for breadboarding CPUs.
i would love having stuff on hand if it didnt cost money
I also salvage useful parts from junked equipment, increasing my inventory at the cost of some time (but I enjoy taking stuff apart, so that's basically playtime)
taking apart ewaste and desoldering makes up 90% of my stuff
yeah i dissasemble things almost compulsively
like i used to always carry a screwdriver but i would find myself automatically taking apart other peoples stuff without even thinking about it so i stopped 😅
What parts do you salvage? I went through a phase where I would basically depopulate every through-hole component on a circuit board, but not once have I found a use for any of those components
Is there an esp32-s3 qt py in the works or did i just have a really good dream the other day
A GK question, who maneges files or documents in royal court
I'll normally target mechanical stuff (motors, rollers, gears, pulleys, belts, encoders, etc.), indicators (LEDs, displays, meters), speakers, power supplies, switches, transformers, housing bits that look re-usable, and particularly interesting components (big resistors, capacitors, useful chips especially if they're socketed). However I don't pull parts from PCBs nearly as much as I used to. I do end up using salvaged parts, not a whole lot of them. Since I build costumes and props, I'm always on the lookout for interesting looking bits I can re-use for those.
Gotcha, thanks!
Anyone here ever automated their window blinds?
hk fedex how much time does it takes to come to europe from china?
I already asked the seller, but I can't wait much longer
if it helps it does cost 45 dollars...
Unfortunately, there tends to be a lot more variables when estimating shipping time for international deliveries. I'm less familiar with Europe, but air travel would be probably anywhere from a few days to two weeks, plus whatever time is needed for handling and customs, etc.
And travel by boat or ground could be delayed even more...
Fed ex in my area is the slowest. Ive had stuff not make it out of the hub for over a month
sim800l looks to be 4g/3/2g
but since 3/2g around here is gone
doesn't exist any other cheapo gsm module for 4/5g?
Nope, only moderately expensive 4g/5g modules.
Cheapest 4G option looks to be just shy of 40USD, actually. I guess that's probably cheapo in this context. Depending on where in the world you are, though, it might not work...

some lipo battery distrubutors?
on octoparts I'm finding it difficult to deal
ebay I can get battery packs but meh
digikey, arrow doesn't look that they have a wide selection?
Alibaba for bare cells and digikey for protection circuits
All the actual batteries are just as unsafe, the important part is protection
if you are buying ones to substitute for Adafruit LiPo's, note that the polarity of the JST plug is not standardized. Adafruit's are all one way, but there are other mfrs that use the opposite polarity. So check carefully before plugging in.
Released: https://www.adafruit.com/product/5426 I believe there is a variant under development that has a version of the ESP-32-S3 with PSRAM, but don't quote me on that.
wow, a welcome surprise
anyone know where I can get support for shipping / purchases?
Email support@adafruit.com
I was looking to make a battery pack for my bike
but I'm somewhat confused with bms or protection circuits
in many I do see an out for powering x stuff
and an in for powering the battery
but what if I do plan to use the motor as a generator?
are there any specific cheap bms or extra circuit that can do that, or do I need to try to make something that deviates the power coming from the motor to the in of the bms?
You'll probably need some extra switching and control circuitry to use the same motor as a generator.
Is this the new off topic chat?
for that I'm using vesc... the problem now to deal with batteries (flipsky 75100)... perhaps do you have any suggested keywords to google?
looking up at like battery pack reverse charging, bms reverse charging, current deviator, I'm finding nothing
Thanks 🙂
i forgot it's in the pinned messages for this channel as well
Does anyone else use an iPad as a second monitor with a windows machine? It will not stop asking me to trust my device
I also have a brand new Apple cable that I'm using and it keeps disconnecting
Imagine if you can get any of Adafruit's products shipped to your local Micro Center to pickup in-store. That way you can buy more products at a physical retail location, instead of getting products shipped to your house. This type of bulk shipment should theoretically be cheaper than individual shipments, so hopefully if this ever happens, Adafruit can pass on the slight savings onto customers.
Doesn’t micro center sell Adafruit products already?
"regenerative braking"?
Yes, but only a limited selection.
ADHD is both a blessing and curse. On one hand, I can hyper-fixate on one thing and work on it for hours at a time, while on the other it makes it nearly impossible to focus on things my mind deems uninteresting, which is MORE THAN HALF of my daily responsibilities while not on medication.
bit of a vent ig, sorry.
no results
flipsky does actually sell bms with Bi-directional current pins, but they are over 200 too expensive for my pockets
There is going to be the first local 2600 meeting in my area starting next month, well actually it's next Friday. I am looking forward to it.
Interesting, I didn’t realize a hydraulic metal press would be relatively inexpensive
probably I can get away with d
some diodes, but probably I will do a bad circuit
I was similarly pleasantly surprised to find an inexpensive sheet metal brake that seems quite sufficient for my needs.
I have plans to work with aluminum sheet metal for an electric go kart project so I'm looking at a manual 30" break/bend press from Harbor Freight
my dad suggested some low temp aluminum welding rods you can use with a torch that I am going to try out on some tags to practice to see if I can do it without a TIG or stick welder
I'm also working with sheet aluminum. I looked at the Harbor Freight offerings, but eventually settled on one sold by Eastwood. There seem to be several vendors for essentially the same units.
neat, RC remote?
Yup. Replicating the look of the 72MHz Futaba ones from the 70s, but it will be operating at 2.4GHz.
Thanks! I've been learning how to use the sheet metal tools in Fusion 360
I plan to get my feet wet with sheet metal assembly in fusion as I'll need to model my go kart pieces before actually making them 🙂
I also found a nice 1800W 48V motor that is used for electric go karts that's reasonable priced.
probably the battery is the most expensive part of it
For reference, the Fusion render
i'll need probably a 48V 50Ah battery
That sounds like the battery in my electric tractor
oh yeah, i do remember you sharing that before. pretty impressed by how well fusion works for sheet metal parts
I found some very helpful instructional videos
I am torn though on if I want to make more of like a racing kind of go kart that's low to the ground or if I want to make more of an all terrain go kart
both seem like really fun options
or maybe I just build both and swap the battery between the two
I suppose active suspension is probably not something you want to start with
The "why not both?" approach
yeah, then just swap wheels
I wonder if I should use a variable speed differential or if I want to try and use a transmission
or maybe direct drive is better
more torque anyway
Chains and belts are popular, but there are lots of options. A variable speed hydraulic transmission, however, is probably power-robbing overkill.
you think maybe a 1:4 ratio is reasonable?
