Does anyone here know of a good GUI that might exist for my raspberry pi touchscreen that works to control a pihole? I am tinkering around and have pihole running on a dedicated linux server, but it would be cool to have my little raspberry pi screen to start or stop the server.
RP2040!
Nice! I've never used one, or any of the modern MCUs for that matter. Last MCU I ever used was the atmega328P! Do you program it in Python, or directly write C/C++ for it?
CircuitPython, my best friend
I'm actually writing python rn. Sadly, not the circuit variety.
Lose enough, lol
Autocorrect actually improved this sentence š
Now it reads more like, "it's your loss" :P
I meant close XD
I've been thinking of getting one of those cheap Chinese RISC-V devboards -- It might be fun to play around with the architecture a little
The real problem would be to actually find time to play around with it š
Lol, thatās always a challenge
Gotta build a time machine
Next time on The Onion: Local Person Finds A Way To Reverse Entropy Just To Have More Time For Personal Projects
just wait it out a few more million years and days will be 30h long.
I mean, over here today will be 25 hours long
Why would a day be longer or shorter than usual?
Actually charging hours, lol
On it.
These little heating pads donāt get as hot as I hoped DX
They hit like 100F max without touching anything, and donāt seem to draw the full 1A theyāre supposed to at 5V
I guess you could sandwich one in insulating material and see if it reaches a higher temperature, but that way lies unintended combustion
Not sure why it wouldnāt draw the specified 1Aā¦
It could be a PTC device that self-regulates. If so, it might draw the specified current in a cold enough environment
heh the "Starfruit" brand concept is really amusing to me because i'm pretty sure that a star fruit (carambola) is what the actual Adafruit logo design is modeled after
or Adabucks (coffee and...)
i think most metallic conductors have a positive temperature coefficient of resistance, so if you want to see it draw more current, maybe try putting it somewhere really cold? or pulse it briefly at room temperature while monitoring the current waveform and see what the initial current surge peaks at
if you look at the datasheets for the actual textile, it gives various (higher) currents and temperatures at higher input voltages
Work tool pouch
That looks really slick
Unsurprising
50 bucks.
Thatās not bad. Custom work?
Very nice! My oldest brother has some experience working leather
It's super fun
Made a removable top incase I need to reflash circuitpython
Case for my latest project
Love the everyday carry crab tool (is that what they call it in English? No idea, it's "crab" in my native language, and I never had a need to name it in English š )
TIL this tool is "pliers" too
"Crab tool" sounds more badass though :P
And now all I see is the person using them walking like a crab in between areas they use their pliers
HR talked to me about that. I'm not allowed anymore.
You now have to name it "ferris", after the rust crab logo
@tardy badger is this good
Saw your post on twitter and picked some up. I like how they extend past the end.
Got a synth plug for the macropad from todbot too.
Wish Tindie had a category for circuit python.
Keyswitch dimensions is 1.5cm x 1.5 cm right?
For which key switches? Are you asking for pcb footprint? Adafruit usually has that stuff documented in the product page or learn guide download.
Is there a common place people get electronics cabinets to mount things like din rails? I've seen people do the rubbermaid thing, but i want something a bit more permanent and kick proof .
Digi-Key sells din rail enclosures I believe
yes but i think the prices are horrible. ill check again though
sometiems they surprise me
Amazon had a few
Some pvc, some 19ā rack mountable
Purchase NEMA enclosures with DIN rail for industrial applications from Polycase. DIN rail enclosures are durable for any environment. Browse electrical enclosures with 35mm DIN rail kits that are custom-cut and made to fit inside the enclosures.
Seems reasonable
Not even NEMA enclosures that are for industrial applications?
im not sure. maybe it fine. the nema stuff i dont think matters much. i just know the drive heat up and i need to cut holes to put fans.
well one fan and one filter
since its little
my big machine had an actual refridgerator
I donāt see why it would be unreasonable to cut a fan/filter hole
Chery mx keyboard switches
you need the back plate, rails, the drive is 6" deep and it needs 2" in front of it
cherry spacing is 19.05mm on centre. the actual switch plate hole is 14mm
so 1.50 cm width and height
15.6mm is the model i have, but its not a cad model from cherry directly.
i dont have calipers on my desk to measure one right now
I only carved out 1.5cm
Should be able to force it in right?
im talking plate mount as well
can you explain what you are doing? you want clearance amount for a borad mount switch?
or the socket for a plate mount switch
Top is for switch
Side for USB c
finest cardboardium alloy
Is the hole enough for a cherry 3 pin switch
you need to answer my question first
Normal 3pin plate mount switch
The hotplug ones
thats the outer diemnsion that sits on the plate. but the "snap" in clips need 14mm, and a 1.5ish mm thickness
or it will just fall out
So mine 1.5 is ok?
NO
needs to be 14mm
15mm is way too big
if you cant be that precise, you are better to use the pcb as the structural mount
but then, that needs to be firmly secured to the housing
Ok I have it taped to match alr
Would super glue hold it more firm
you could glue it in permanent i guess.
i mean, the cardboard is not going to hold it anyway. i am assuming thats just for testing
I can hold my phone so I guess it can hold that too
It is lighter than a phone though
this would work, but its twice the price of the steel one. (in cdn dollars plus shipping)
Tested pressure on the support point alr
Doesn't bend too much when I press it cz there's another cardboard under it
well, i guess there sone way to find out
All things that could impact I tested alr
I just want them hotter XD trying to melt wax. Guess Iāll try 12V since theyāre rated for that⦠I just thought it was weird that it said 5V would draw 1A but it was more like 600mA
I suspect they're low-precision devices, and the spec might be for designers who want to know "what's the most current my transistor would have to handle if I'm powering this at 5V?" so it may be a maximum value, not a nominal one.
However, I'm (still) just guessing
Gonna connect to 12V and see if it catches fire 
I have been known to drive such devices from a current regulated supply so they'll get the current I specify, at whatever voltage required (within limits)
I wish I had a current regulated supply⦠I had one hooked up to USB, and my powered hub was putting out 5.27V, and it drew 530mA on that
The hub can do 1.5A
Depending on the parts you have lying around and how much you enjoy that kind of tinkering, you can roll your own
I tried the top design first (current sensing resistor in the feedback loop of an op-amp), but eventually settled for the simpler 2-transistor lashup at the bottom.
Parts choices were (as always) driven more by whatever I had lying around than engineering.
This tends to be my mode of engineering as well
I just formally verified my first design. Exciting!
was that last adafruit restock in feb? I might have to pay scalper prices
@delicate stream š
For which product?
I got mine relatively quickly from Digikey a few months ago. The ones I ordered from Mouser keep getting pushed back.
I placed orders with both because they allow backordering.
anyone know of any open source wireframing and diagramming software?
alternatives to lucidchart, justinmind, adobe, etc
I heard miro and penpot were pretty good, but you have to setup a penpot server. Figma too but I didnt really like it
How about dia?
Sup guys
Same
Im a hobby engineer/artist I guess
Guess I donāt have image perms or I would show ever body
Thanks
Itās Bluetooth stereo and charging station
The first one caught fire š„ lol using what I had.. this one is safe though
The newest BT robot is called DaBruce and he is battery powered and I added a BMS to charge the batteries with are 3 18650 lithium ions
All went well but I think I killed the batteries
It recharged fine 3 times but super fast and may have overheated them
See a need, fill a need
Hereās my junkbots Skip and Bitzy
Those are named as amazing as they look!
Haha thank you. Naming was the hardest part!
They are fully animated.
Skip plays records and Bitzy does the digital stuff š
That's so cool! I have a couple random things like old printers... maybe that would be a good junkbot project! I don't need more projects but that's never stopped me before
I love them! :D
Seriously, thanks for showing them here, they're really charming designs
Thanks so much! Very encouraging to hear š
I LOVE this guy, and their zen posture!
I have rebuild him.. Iām done working out the kinks just need better speakers š hard to find 1 inch that donāt sound scratchy so imma add a low pass filter

Love ur work also letās be friends š
I mean Elon just changed the logo of twitter to DOGE
No way

how long does usps first class usually take?
Usually 2-5 days
It depends
Iāve seen things go from Utah to Florida in 2 days, Iāve also seen it take the full 5 days
ok, thank you
Do you want to flash a bootloader to use the usual Arduino process, or do you want to flash a full custom image?
fully customized ma man! š

I almost got to see it! I was visiting a friend a few miles away, but Sam was busy (for good reasons) and our schedules didn't align. A railroad strike made it unworkable for me to come back out when he was free.
D'aww, that's too bad
I saw this meme on the dying birb site and figured a few people would enjoy the dad humor
Hey all - I just found this older vid by Dan H which is really great. I've been doing CP for several months, and still learned a lot from this. Check it out : https://www.youtube.com/watch?v=1rkM0Ow8Pkc
Another spinoff of my logical analyzer device/Twitter bot, a discord bot that takes a username and number of messages and then analyzes them and responds with fallacies if there are any.
How does it work?
The discord bot uses GPT3.5Turbo cuz it's 10x less than davinci which is less than GPT4. The prompt varies slightly by platform. I spent $1 in the last few days with 3.5 if I was using gpt4 it would have been $30
The Twitter bot is the most complex 2nd to the raspberry pi USB soundcard device that uses whisper for stt.
The main trick for the device is getting GPT to format the output so I can use regex on it and also turning the temperature to zero so there is no randomness in the responses
@urban arrow John Gallaugher has an excellent series of video tutorials for beginners to Circuit Python. I watch all of his videos because there's always some neat tips & tricks to pick up. He does go quite fast to pack as much into a short video. You are expected to pause/replay a lot if you're following along with a project to help digest the material. If he slowed things down his videos would be 3x times longer but thanks to youtube you have a pause buton. š
An introduction to CircuitPython using the Adafruit CircuitPlayground Bluefruit. This playlist was prepared for Prof. John Gallaugher's undergraduate Physical Computing students, but feel free to follow along and share with others. If you like what you see, please let me know!

Hacked mindflex headband -> MCU -> relay -> plug in air freshener
Did you just say you activated an air freshener with your mind?
is mind-reading tech that good yet
As long as the user is trained to trigger a specific EEG potential, and the system is reliable enough to consistently record it, a simple "on/off switch" BCI can be constructed. As far as I know, the number of samples required to reliably do so is high enough for the baudrate of such an interface to be fairly low
The mindflex is reasonably good at detecting concentration levels. I guess you could threshold that. More of a silly idea than anything else tho
can anyone tell me what cable's being used here to connect the bluefruit circuit board to the tft gizmo display?
They are using screws and nuts
The connector on the bottom with the black and red wires is the battery connector
I donāt think the cable goes to the Tft gizmo, thatās a battery connector IIRC
Itās just bolted directly to the Bluefruit, the gizmo comes with m3 standoffs soldered to it, so the ācableā would be the M3 screws that hold them together.
https://www.adafruit.com/product/4367 shows it in a better view.
Extend and expand your Circuit Playground projects with a bolt on TFT Gizmo that lets you add a lovely color display in a sturdy and reliable fashion. This PCB looks just like a round TFT ...
The 2-pin connector at the bottom of the gizmo is an amplifier output to connect to a speaker. š
Would you be able to help with the gizmo itself? I've been trying to get my TFT gizmo to display an image but nothing I do gets it to turn on, I thought maybe it was the pins, but could it be that the device is faulty?
The screws are tight I'm really not sure
What should turn it on, essentially?
which circuit playground board are you using?
bluefruit
are you able to get the BOOT folder to show up if you double press reset?
on the gizmo?
oh yeah I found it
download and try the ready to go UF2 from here:
https://learn.adafruit.com/adafruit-tft-gizmo/tft-gizmo-test
the one for the bluefruit
drag the UF2 file to the BOOT folder
gizmo should look like example gif at top of page after UF2 is copied
if that does not work, then there is a connection or other hardware issue
š Im asking chat gpt how to code and its...um kind of crazy how its basically taking place of a teacher.
I wonder how accurate it is at generating c code
void setup() {
// Initialize the USART/UART interface with 9600 baud rate
Serial.begin(9600);
}
void loop() {
// Read the analog value from A0
int analogValue = analogRead(A0);
// Convert the analog value to voltage (assuming 5V reference)
float voltage = analogValue * (5.0 / 1023.0);
// Format the data as a string
String dataString = "Analog Value: " + String(analogValue) + ", Voltage: " + String(voltage) + "V";
// Send the data via USART/UART
Serial.println(dataString);
// Delay for a short period of time (optional)
delay(1000);
}

If you think chatGPT will take the place of a teacher then you'll be going to the school of "plausibly correct but incorrect".
Welcome to Xavier's school of "Gifted Plausibility Training"
Xavierās School of Overconfidence?
Can an AI really have overconfidence? It does seem like the answers presented are factual most times when they are not.
I mean, it's been trained on internet data :P
because the internet is never wrong, brilliant plan, what could possibly go wrong.
from a post we have in #welcome:
ChatGPT
ChatGPT can give plausible-looking answers to questions. But you can't trust ChatGPT as a source of knowledge. It doesn't "know" anything. It could be right, or it could be completely wrong (and appear confident), and you can't tell. It's just cobbling together phrases from a large language model, and it doesn't do attribution. It's like asking a parrot with a very large memory a question. We recommend you use a search engine instead.
i have had it invent non-existent libraries out of whole cloth (e.g. a Trinket_M0 library that resembled the CIrcuit Playground library)
Oh yes ofc š
its just interesting
Is there any way to turn off the "for you" function on you tube?
don't log in? (I have never logged in to YouTube)
Xavierās school of hallucinations
What strikes me about it is that it substitutes verbosity and confident presentation for actual knowledge. I've worked with quite a few people who use similar strategies. They tend to get promoted into middle management.
And thus the circle of toxicity lives on
lion king music plays
Well, it certainly explains why so many people think these bots can actually reason. Most folks can't tell the difference between competence and confidence.
Thinking they can reason is a reasonable response, thinking they know that they are talking to a real person takes faith
stares at Kevin Roose
My secret is to have the same affect but only when I know things. When I don't know things, I don't say anything. Numerous people think my top of the bell curve self is a genius.
yea but then you get those unfriendly types who get angry and are like "Well can you find someone who does know?" when you are the closest expert at that point.
(see also: the Dunning-Kruger effect)
How dare you follow the normal distribution š
An interesting thing thatās been studied a lot is the intelligence to confidence of people
People with lower intelligence tend to be far more confident while people with higher intelligence tend to be unsure more often than they feel confident
Which means average intelligence leads to fairly even confidence
Ive seen this first hand when dealing with people who try to talk outside their knowledge base. Its also why I keep my mouth shut
I will only talk to a point in which im fairly sure, but even then my brain sprinkles in ābut im not confidentā or ābut I could be wrongā
anxiety be like:
All this follows: the more I learn, the more I realize how little I know.
Imposter Syndrome enters the chat
It's funny though, how our first actual conversational AI ended up mechanically mimicking the overconfidence of an internet denizen
I wouldnt say I was over confident, I just thought it was interesting. I know enough not to trust it. I also know enough to verify said thing. But its like anything on the web, trust but verify any and all statements
For some reason, the way it pads over answers it doesn't really "know" what to do with reminds me of a pupil who doesn't actually know the answer trying to pad their answer with as many "big words" as possible to try to hide that they haven't studied/done the assignment at all (and gain time to hopefully remember the answer)
The one on Bing referred to a nonexistent paper by a person who does exist, and she resented getting requests for copies of a paper she didn't write. In another instance, it gave out its phone number, which belonged to someone who didn't appreciate all the curious calls.
And when you point out something it says is wrong, it doubles down and fabricates more bogus evidence for its assertions.
ChatGPT has done that (ie. generate non-existent paper titles authored by people who actually are in the field the prompt is about) to me too
Yep. I've definitely worked with people like that.
Current "AI" seems to be best at entertainment and fiction writing. Too bad the hype is going to get it pushed into things that matter, where wrong answers have consequences.
Well, I can tell you the last place it will land will be software engineering for defense articles
Itāll be explored because the government likes to save money but will ultimately be rejected because it inserts far too much uncertainty and confidence in outputs that will largely be flawed. Not to mention security concerns
I dunno, the military still uses MICROS~1
They still use lots of stuff
But AI/ML research is not very well funded outside of universities right now
I dunno, it wrote a complicated goertzel circuitpython function for me recently. I wouldnāt have been able to do the math myself. Or, I would have, but it would have taken weeks. Luckily Iām not working on anything important.
Is goertzel what they use to recognize chords in music training software?
Iām using it to detect DTMF tones
Itās faster than FFT when youāre just trying to pick out a few frequencies
I'm thinking of implementing a software modem with it (just need two frequencies)
As the average social user
I somewhat dislike the one of bing though, because it looks like it gets keywords from your input then search that, not that much of an ai
But then chatgpt here got banned š¤¦āāļø
Iāve been meaning to thank you for pointing me down a good path for my phone project
I thought Jepler got it to admit 2+2= 5 though. š
For sufficiently large values of 2...
āYou must take your ChatGPT into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.ā :P
Oh, yeah, that is correct
@late fulcrum , do you know Chinese / Japanese?
I was surprised seeing somebody use the åÆćemoji
No, it just interests me and I'm eternally curious.
Makes sense! (In Japanese) The character means "passable/acceptable", although you probably already know this.
I spent a while poring over Unicode tables and looking up radicals, trying to figure out what some of the emoji are for. I ended up finding out arcana like one set was part of a proposal for Japanese TV symbols http://www.unicode.org/L2/L2007/07259-japanese-tv.pdf
I've gotten a lot of use out of the "handwrite" option in Google Translate to find out what a particular hanzi/kanji was.
I wonder how come some of them didn't get English variants. For example, we have š which is close to åÆ , but there's no equivalent for ē§
Yeah, I just couldn't be bothered to look up the actual emoji, and typed the character instead. Apparently, it's :secret:, which would've been easy
I expected it to be u\d\d\d\d, like the other emoji of CJK origin
It's an odd mix. Most of them are a hex code, but there are also \š (š), \šļø (šļø), \š (š, what were they thinking?), and \ćļø (ćļø)
Whoops goofed quoting : marks
TIL discord treats natively-inputted emoji differently than those inputted via the :: mechanism
So I learned 2 things from one mistake! This is a good day!
So how do you escape the : character so you can show the shortcut code?
I get diamonds with question marks for some of them
Ah, your computer may not be using a typeface with some of the newer emoji
I'm on my phone
\:blah\:
I'm kind of surprised mine does, I'm running a 5 year old OS
I heard Discord updated some of their emoji, I assume it just hasn't rolled over to my phone yet
Ah, I had escaped the leading : but not both of them.
Huh, updated Discord but it didn't show anything different
It seems natively inputting emoji bypasses discord's emoji and leads to them being rendered by the whatever mechanisms the local OS has
So, ćļø is treated differently to ć
....aaaand it's not. Not on my system.
š
@late fulcrum what did you do? You broke it! :P
\šµ
LOL I think I know what happened
You can escape an emoji with \
...in which case it will bypass discord's emoji handling
Evidence: The green tea above
I suspect this is not intended
My phone shows them 3 different ways?
You've held on to one of the last phones with a small screen. Good job!
That makes room for the āØļø
Does yours have a physical keyboard?
Yup!
An even rarer specimen!
That's cool.
Huh! Do you find it's usually easier, or more difficult to use?
What model is it? I can't even properly type on a touch screen
i only have 1 phone with a keypad but it's T3 (with a web browser though)
Blackberry Key2. I find it much easier than a featureless surface with no tactile feedback. However, it's an older G4 phone, but I have an Astro Slide G5 on order.
:\ It probably hasn't been updated firmware-wise in years
You can still get the BBQ's from solder party. Though not sure how well Fona support still is. I wouldn't mind rolling my own someday.
Blackberry is fairly good about OS updates, unfortunately, my original one went swimming and the gray-market replacement doesn't download updates.
BBQ?
blackberry keyboard that'll run on a microcontroller
Ah
is there a blackberry q? That would make a lot of sense.
Yeah.
I get this when I run a security scan on a gray market phone š¦
A BB Q20 Keyboard with trackpad in a portable format. Easily add a QWERTY keyboard to your project!
Yeeeeah, I probably wouldn't trust this one?
Oh hey it's arturo
That one is fine it's arturo yeah, he does some boards for adafruit occasionally too. Solder party is a trust worthy vendor.
Who is Arturo?
I bought the FeatherWing version https://www.tindie.com/products/arturo182/keyboard-featherwing-qwerty-keyboard-26-lcd/
An easy way to add a handheld Qwerty keyboard and a 2.6ā color display (+ more) to your project!
I think ningen was talking about madbodger's phone
i wanted the featherwing version but they ran out š¦
That is correct!
oh that phone, yes, cursed for sure.
Yeah, I'm in the process of trying to build a FrankenPhone. I figured the Astro would ship sooner, but since it's not, I want a more-secure phone again.
Every time someone mentions the BBQ20 keyboard from the blackberry, all I think of is a weekend cookout
It's the phone to buy if you have a clearance!
(Please don't)
Few security issues with this one either
Caveman is perfect for security clearance. Aversion to technology, canāt speak English, has no idea what anything is.
same. BBQ is memorable but my first thought is... how hot does it get because that name sounds like it should be hot.
Just easier to wire tap
Well, all land lines suck at security anyway
nothing is secure, only the illusion of it
a mood
i could link to studies showing how the government invested in reading people's dreams, like getting an actual visual image of their dreams.
Me: makes something I think is cool
My Brain: āeveryone is going to hate itā
Me: quietly puts it down until I have the confidence to share
that's not conspiracy theory stuff that's fact. please don't go down conspiracy theory rabbit holes, it's part of the code of conduct.
My version is "it's already been done to death"
Why though
Also mood
then i came up with the mantra... others may have done it, better even, but i've never done it.
i think deshipu had a great comment in makercast the other day
"We do not do things because they are easy. We do them because we thought they would be easy."
great twist
I find emulation is the best way to learn and build confidence

If I can make something in a similar way to someone else, and it works then I feel like maybe Iām slightly good enough
If it works it works.
The first time I went on show and tell I was so f'ing nervous. I'd been watching the shows for like a year and like all my personal heros were on there and here I am trying to show off this really basic thing that took months they could have done in a day.
I've never been on S&T for that reason
I still get stage fright going on show & tell... even when I'm recording the podcast
Looking back I wish I'd gotten over that sooner. The skill divide was all in my mind, no one cares about that. Projects of all kinds are welcome and the more I heard that the better I felt about going on and showing stuff.
Iāve been on show and tell multiple times. Still get nervous
Like if it's someone's first time ever getting an LED to blink, and it was hard to do, learn a new foreign language, and implement it. I enjoy seeing that.
Maybe if I do more YouTube stuff, I'll get the confidence to
Doesn't matter how basic you think the project is. If you get a sense of pride in your progress and want to show the world "I did a thing". That's literally part of the name Show & Tell.
I just wish there were more people, more projects, more time to do like an hour long version.
Yeah I think everyone gets nervous even the host lol
Remember show & tell in kindergarden? Were you nervous then? Some things never change. Getting up in front of everyone is exactly how you overcome the anxiety.
Everyone here is so nice and supportive it's actually easy and that's one of the many reasons I love this community. There are in fact some electronic communities that have a very toxic exclusive mindset of one upmanship, arrogance, belittling comments, etc.... so this place is actually pretty amazing.
I might actually do a thing on show and tell
I urge everyone to participate in show & tell no matter the status or basis of your project. The positivity is invigorating. I've never regretted showing a project off there. Actually, just the opposite, people have given me ideas on how to improve things and being positive influences. Everyone here is just great.
Is there a limit to the number of items one can show off at one time
Cause I have... several projects
i think it's more time based which is dynamic based on the amount of people in line. which you'll never know how many there are. that's part of the hosts job i guess.
usually 1-2 minutes depending on time
Right, two minutes is typical, so feel free to return another time with something else.
if there aren't many people then maybe 3-4 minutes, the host will let you know approximately to "be fast" 1 minute or "take your time" 2 minutes..
yup and if you don't get it all in, there's always next week, because the show isn't dependent on 1 particular host. the show will happen even if... perhaps especially if there's a pandemic. š
i think it would be cool to get educators into it and live stream pre-recorded videos of classroom projects with circuit playgrounds and stuff like that.
digikey showed a halloween project of a classroom full of pumpkin projects last year using them. i thought that was just awesome. they all programmed different midi music into them using makecode too. i love seeing stuff like that.
like here's one https://blog.adafruit.com/2022/10/27/halloween-monsters-with-crickit-and-circuit-playground-express-electronichalloween-2/
very basic stuff cobbled together is still not easy if you've never done it before. seeing an entire classroom do stuff just warms my heart.
I cram in as many projects in my 2 minutes as possible
Lol

Petition: Can we call all AI-generated images purporting to be images of real events involving notable people "puffy Popes"? :P
Automated fictitious characters and fictional events really does seem to be AI's forte. Imagine getting AI to write an entire book for you.
If you aren't already publishing a constant stream of AI generated children's books with AI audiobook narration you're behind
Jepler's already got it automatically creating a Zork style game which is impressive. I could see it easily being adapted in the future to create entire fictional universes.
I would like to automate applying for menial roles in call centers and tech support and integrate voice recognition with chatgpt to handle prompts and generate responses with elevenlabs, imagine automating 20 jobs at the same time
They've already been doing that for the past decade. Every website that has those little "live help chat" popups is usually AI responses.
I think games will be drastically different for games that have choices that change the games outcome. Instead of a set of 20 different possible endings (Fallout 3) which is determined by different choice paths during the course of the game there could be an infinite amount of dynamically generate paths and outcomes.
I think the route Jepler chose to dive straight into with it was a well suited application for it.
How long until we have "AI Hallucination Ending%" speedruns?
can AI illustrate dreams yet, I think there was a very primitive attempt a decade ago

Hi everyone!
I'm guessing from 3G to 4G
The new networks need higher accuracy I guess?
I don't know if it's that (a rubidium clock seems more accurate than necessary to me), or a change in technology.
Im ok I got vaccinated 4 times so I have quad-5G directly in my body š¤£
Who need kindle when you can directly download it in your brain at 1 gigabits/s ?
You most likely got the polarity backwards with the battery you were using it with. That's how that happens. The wire turns into a resistor until it's red hot and looks like a lightbulb filament, either the wire burns itself out or it smokes so much it can start a fire. I know this story very well. I've done it many times.

I've seen the magic smoke escape (multiple times too!), but never in such an extreme and... fiery fashion. I have a feeling they ramped up the voltage to exaggerate the effect...
On the other hand, I may be better at unplugging things when I see smoke :P
For sure it's less dramatic with 4.2V vs 12V. As you can see in acthpau's image the result is pretty much the same eventually.
It happens so often that Adafruit has put out videos warning people about it and people still do it. It's just one of those things. This is why a lot of companies go with proprietary connectors so there's no possibility of connecting things incorrectly.
When using discount lipo batteries, keep an eye on those connectors. Browse lipo batts at Adafruit:

It's the common JST connector that throws people off. You really need to test a lipo's polarity before using it with an Adafruit board. If you buy batteries from Adafruit it helps prevent incidents like this as Adafruit uses 1 wiring scheme for all their charge ports and batteries. The stuff you get from other retailers might not be wired the same way.
or if using a JST connector yourself to splice in a battery to a JST you can get that backwards and poof, smoke.
Check the learn guide for your board. Each one has the correct polarity indicated for the battery terminals.
Here's a nice quick video on how to test for polarity. This will ensure in the future that any battery you use you will know for sure it's connected correctly. https://www.youtube.com/watch?v=xoUHbf_bRxw
Just a quick tutorial video.

THANKS FOR WATCHING!
But most feather boards have a voltage switching/reverse protection diode on the lipo input
So that shouldn't happen unless there's a short somewhere
and if reverse current flowed through the board it would probably burn the board and ICs instead of the wire
probably
@brazen wyvern What board did it happen with?
Even if a sub-component is UL rated (indicated by the backwards RU symbol) it is only certified for suitability for a very specific purpose. If that component is used with something it isn't designed to be used with, the rating is void. I am curious what that battery cable was connected to, because I am not aware of a single cell LiPo battery that is capable of putting out enough amps to do that to the wires those things are made of, unless maybe the battery itself was defective, or the system was back-fed with a higher power unregulated supply.
There's a lack of info with the image, no way to know for now.
You just love iOS development
this happened in the middle of operation, so I'm sure the polarity is right
Then definitely contact support via email so they can follow up with you. They'll want to be made aware if it's some type of defect.
How long after powering up the board did it happen? Was it the first time using the battery and JST with that board?
like 100+ hrs
average current draw < 1A
the cable is the only thing that was damaged
not even the connectors on the both side

how to use PiEEG with raspberry pi 4 python
i need to make a brain controlled wheelchair with PiEEG using python
i dont know anything about eeg
please help me!
It looks like that's a relatively new board, but there are some Python examples in their GitHub, like controlling a robot with blinking: https://github.com/HackerBCI/EEGwithRaspberryPI Mostly you're going to be getting the raw EEG data over SPI, though, so you'll probably need to do some data processing of your own to turn it into useful control signals.
Also, please don't post the same question to multiple channels, since it means the replies and conversations about it will get scattered.
@night crescent I sent an email about a job posting and I was told to do a follow up email a week later and I did but I have not received a response yet and it has been about an additional week. Please advize <3
hi does anyone know what teh fov of the adafruit as7341 is ? i cant find it in the datasheet ?
are you applying for a job or wanting to post a job?
I wanted to post a job to get help for circuit python dealing with NFC tags and hardware from adafruit. In the email I included all the information.
The job posting service is on something of a hiatus right now while we figure out how to reorganize it. The postings you made here are ok.
okay, so to confirm it is okay if I job post in circuit python? Thank you for taking the time to clarify <3
yes, you can post it one time
Thank you! <3

To make a bci controlled wheelchair we need alpha or beta signal

danh: what we talked about is the main reason I quit chatGPT and it's stubborness in accepting any part of someone else viewpoint
Because of this I never want an AI in my house ever in my life or controlling any furniture or appliance I own
Because the stubborness and being convinced of false information sounds like a good plan to get me killed while it insists Im faking it
its lack of uncertainty and lack of attribution make for a killer combination
Being wrong on a chip and circuitpython is one thing but if it is feed information on says appliances / electronic / safety equipment it will just insist it is 100% correct while hurting peoples
repasting something I posted elsewhere:
This is an interesting observation on how to think about ChatGPT:
Something that seems fundamental to me about ChatGPT, which gets lost over and over again: When you enter text into it, you're asking "What would a response to this sound like?" If you put in a scientific question, and it comes back with a response citing a non-existent paper with a plausible title, using a real journal name and an author name who's written things related to your question, it's not being tricky or telling lies or doing anything at all surprising! This is what a response to that question would sound like! It did the thing! But people keep wanting the "say something that sounds like an answer" machine to be doing something else, and believing it is doing something else. It's good at generating things that sound like responses to being told it was wrong, so people think that it's engaging in introspection or looking up more information or something, but it's not, it's only, ever, saying something that sounds like the next bit of the conversation.
From https://social.coop/@DrewKadel/110154048390452046
And you never know if your opposite political opinion sounds like a good way to have hold a grunge against you
It straight up told me to respect its beliefs at some point..
the "or else" wasn't far off at this point
it's very hard not to anthropomorphize its responses, but you have to keep not doing that
sigh this response kinda annoy me
Im not anthroporphizeitwhatever
Im saying a safety mechanism shouldn't be conditional on what is consider a correct way to use it
That is why I can't trust it for anything related to safety
i can't trust it for anything at all
Because every time I ask it a simple question it has to give me 3 paragraphs of moralistic c*** and who could be offended by any part of my question even if it's a 100% technical question
sometimes it's a really good interactive encyclopedia though and that is where it can sometimes shine when I don't have access to the data it was trained on for free
But I feel like to waste so much time retelling it what question you asked every 4-5 prompts, and that you don't want to know how bad the french-german wars in the 1870 wars and who they offended you just want to know the goods that cologne produced back then that it gets very tiring and I probably would have found faster reading physical books
Also teacher saying it's very hard to detect is BS. Very easy to tell because it can't help write in a positive vibe/moralistic style
have to be afk, but interesting observations
I wonder if gpt-j is the same, ideally I would like an NLP that is basically a big knowledge base so it can give me a cursory / summary introduction to a topic
and instead of making up answers would say something like: the climate of cologne, germany was X and it was near trade roads leading to Y and Z and thus it is very probable that it was involved in producing these goods even if I don't have it in my training data
Some peoples seems charmed by its code-writing "abilities" but I guess they didn't actually run the code or check if it is fast and optimized. And when you ask follow-up questions on it it can't actually put any details/special cases in the code
It even fails basic questions like how to declare members variable in a new declaration in C#
it will tell you it is new({}); when it is new{};
It used to be a bit better at citing things and making logical conclusions in december as it probably had more ressources assigned to it per user but as it gets popular it gets more and more dumbed down
How'd you do that? :O
I do have to admit that sometimes it's entertaining to feed a datasheet to the API version and asks questions and watch how wrong it is
Another classic with the non-API version is that you will specifically tell it in the prompt to not mention a certain place or topic in the answer and they will almost exclusively mention it
Then when you get annoyed telling it you said to not mention it they will "apologize" and do the same again
For instance asks it a top 10 of what cities made quality glass in the renaissance era and not to mention venice because you already know about it
and no matter what you says venice will be #1 kinda like when you search google and put -inurl:pinterest and it's just pinterest links
It can be good for giving large amounts of code quickly... but I think only more advanced users should use it. It definitely is confusing for beginners to get non-working code
Ii just prompted it with ālist ten cities known to make quality glass during the Renaissance. I already know about Venice so exclude itā
I do admit that it is entertaining sometimes like I love to asks it very silly questions and insists it is wrong
if this is to tell me Im wrong
also realize that chatgpt is non-deterministic
And it replied: āSure, here are ten cities known for their glass production during the Renaissance, excluding Veniceā¦ā
and might not give the same answer with the same prompt. I was just pointing out an annoying behaviour it has
Well, there's no actual intelligence behind it..
and this is what exactly to do with what I said except as a condenscending statement towards me ?
Here let me try one reply in the same style: "You need power to use any electronics" That is helpful right?

Being so nihilistic about the human condition won't get you anywhere.

Admitting we don't know something is not abstraction. Just because a statistical model can reproduce remarkably human-like speech, doesn't mean that we ourselves are lookup tables.

Oh oof. This one isn't an issue, it's legitimate. We've blocked the word referring to the Discord subscription because it catches so many spammers, we decided it was more important to stop that than it was to be concerned about real discussions involving it.

I will not use the term uncanny valley, because I to say I dislike the connotations made in the graph which introduced the concept would be an understatement, but, I am kinda creeped out by this robot..?
Lol. It doesn't fit the typical uncanny valley segments since it isn't trying to look human, it's just trying to move like one kinda? But it's gonna take your soul with the lifeless eyes
On the other hand, there is probably some mad engineering (and inverse kinematics!) going on to get the bot to follow the mocap actor.
We need more of this and less ChatGPT.
Folx, show us your useless, but quite charming, robots!
Iām curious if the bot will be doing a pre-programmed routine in the end, or if itāll have some level of autonomy
I mean, disney's been pretty big on animatronics since.... forever, so I'm guessing pre-programmed routine?
It'd also be safer that way...? I think.
I think that there's some plugin for ros
Ah yes, the aptly-named Robot OS. I wish I could get to have a reason to use it one day
Luckily stuff is getting easier
But not it's installation for some reasons
By the way, speaking of cute robots, did you ever play machinarium? I really liked the junkbot designs on that one (and I haven't seen anyone try this kind of art direction again)
https://play-lh.googleusercontent.com/UnB9YP-Gt0FpKHDtv6KmqMJhPuxTCOUTrcFqUUVGmYf56_eAhqWC6wzF2seTEXAh2g=w526-h296-rw
Depends. With THAT bot, it looks like itās very soft and light; probably canāt do much damage, so a mistake isnāt as big of a deal if itās autonomous and goes awry. The issue with pre-programmed if itās interacting with people directly is that people canāt be 100% consistent, so autonomy to allow for correction would be good
I never played it but Iāve seen it, and I do love the junk bots!
I played it when it was new. Only thing I remember are the junkbots and the music
lol
...I hope I didn't just recommend a game with problematic elements I did not notice 10 year ago!

Lol, people probably aren't gonna be too mad at you for talking about something you liked a decade ago that hasn't aged well if you haven't actively been enjoying it. Times change and tastes change, and we forget things
Times change, tastes change, people change. That's true. I still wanted to get that off my chest though š
Lol, fair
Is it just me or is discord being way too pushy about [insert subscription name here] lately?
It's shown me at least 3 such ads today
I am getting more than I used to, but 3/day isn't too onerous when I can dismiss them with a single click. WAY better than "you have to sit through two 2-minute garbage ads to watch this 18-second video"
I do get the impression that their subscription offering isn't selling as well as they'd like though
Their "basic" service too
Ah yeah, that too.
IRC is free.
Problem is, what's replaceable is the protocol. The communities/connections much less so.
I miss the old IRC days
I learned how to set up my own IRC network once
time to make custom irc network with things
I am absolutely, positively sure that went well š
It was actually really fun
I had servers in like 6 countries
US, Canada, and Europe
I'm guessing VPS?
Did it survive for long?
How many users did you have?
where do you see these ads? I don't get ads in Discord... just the interstitials when launching the app initially
Discord itself pops up interstitials about the subscription service while using it
maybe rarely I have to dismiss something, but it's usually pretty clean
Today it's been especially aggressive (to me), which is why I pointed it out
yeah. I get it, they have to make money. I do appreciate the not-usually ads thing, and they do seem at least somewhat respectful of privacy (probably due in no small part to not making the bulk of their profit from 3rd-party ads)
that's a large part of why I'm here, and not ever logged in to YouTube, etc. ...Facebook, all of those
Are they? I literally have no idea. I use it for public chat, so.. yeah.
I think we had like 50-60 users at one point
I read the privacy policy once, I am not a lawyer, but it didn't seem as egregious as the ad-supported social networks. But just being able to have a screen name and no real identifying info is a plus
š
It's the discord subscription popups, yes I'm seeing them a lot more frequently yesterday. They only show up usually after logging into Discord. Since I usually leave Discord open 24/7 I don't notice them. I had to restart yesterday and yes it was popups galore... about 3-4 of them whenever I clicked on something.
Literally can't say the name of the discord subscription as it's a banned word here... interesting.
While it is advertising, it's their own services which they're well within their right to do... but popups are the bane of the internet in any form.
At least you don't get 3 unskippable ads before and after and sometimes in the middle of every message
....or a Microtransaction Mobile Game-like cooldown timer per message

ads in the middle of YT vids drive me nuts, even more than pre-roll
"Content is meant to be enjoyed uninterrupted, as its creators intended" -me
I think someone said it before you XD but that's why I pay for Premium -- so I don't have ads anywhere and the creators still get muns from my views. Plus YouTube Music works well for me
I'd pay for premium if they made the price 1000x what they make from me on ads, but they insist on 2000x.
I have no problem paying for services I value. I should pay up for Discord one of these days. But I mainly go to YT b/c someone or something linked to it, rarely do I go there directly, voluntarily. (and always in a new private tab, and never log in š
so evil ads are the price I pay for my relative anonymity
I live on both XD
I know there's a lot of very useful knowledge there, but I try to avoid services that are: 1. paid for with my personal data; 2. showing content algorithmically as opposed to strict chronological or under my full control.

Heh, I was ordering some other bits, and noticed that. I bought the ones I didn't already have that were still in stock.
I didn't realize they still sold those!
i made a snake
Time for Kabelschlepp
Impressive
nah, i deliberately got rid of the cabble chain
they just get filled up with chips
much nicer to go out the top.
the other cables go out the back
need to wire the spindle controls and then bolt the machine down so it cant wobble.
then its ready to cut
woo
I'm a little jealous, those things are so cool. Can make injection molds.
What do you normally use it for?
well i have to make the keyboard cases
ahh great use
thats the immediate need
i have some other items as well
a dial for my oven
the machine got faster with its new controller. and it was already silly fast
haha
so i need to bolt it down
faster with cnc comes with a learning curve that includes many broken bits i assume
are there automated tools for warning if a bit might break? like a strain gauge pressure sensor?
maybe some kind of pressure transducer?
Youād actually be surprised that faster speeds tend to decrease the amount of bits breaking
Itās weird
yes, that makes no sense to me. š i've never used one though.
testing
4mm 3 flute cutter, 7500mm/m (when the control can keep up) 36000rpm
old control
now its about 3x faster
(for linear moves)
Something about the speed reduces the immediate stress on the bit as material is removed quicker
But bits tend to dull faster because of increased heat
Iād love a nice 3 axis cnc
oh my lord i want one
coolant
wiggling the camera while it was making the hole lol
the camera was not wiggling, the table was. haha.
This is assuming your axis speeds increase proportionally with your spindle speed
150lbs at 0.5G will do that
well yes, theres calculators that tell you what to do for any given material and tool.
Yeah
oh i thought the camera moved from left to right afterwards like someone was holding it. yeah that would be dizzying to watch.
but the general principle is, faster feed relative to spindle rotation means less rubbing, means less heat
i was holding it. but in relative terms. the camera is still haha.
cutting vs rubbing, makes sense for friction heat creep on the sidewalls.
thge ideal is you dont want to heat the cutter. and you dont want to heat the work. you want any heat to go out in the chip.
some materials you have no choice, like stainless steel.
kinda getting deep into material science and physics at that point.
When the greats all work together, wonderful things happen!

i'll stick with the bloops from my FDM for now. CNC is a whole different world.
the sound, gotta have ear plugs, man those things are loud.
yeah. high feed cutters be loud
my other machine is a really old version of that one, from 1996
I'm CNC converting a Sherline tabletop milling machine
we don't have a cnc topic would this stuff normally be in robotics?
sherlines are cute. i used to call them mostly useless, but the newer adaptive cutting softwares actually let them do a lot
um
dunno
theres not much cnc related things on adafruit is there?
maybe we could expand 3D printer topic to include CNC? it would be nice to have a topic for it. I know Melissa just built a custom one. Would be a nice topic to add.
yeah it's really a different thing than 3d printing even though the concept is kind of the same for top down cnc.
yeah. a cnc and a printer are virtually identical machines
maybe i'll bring that up. would love to be able to browse a topic where it's all cnc related
CNC/Milling/Machining/LaserCutting, etc...
i need to dump all my old parts on ebay now. ha. so many motors, drives, control bits from other machines, or i bought then realised were wrong.
oof
guaranteed easy way to half your money. try to make a custom cnc
š
well they sell stepper motors and stuff to make your own. i suppose that would just fit under robotics.
Adafruit doesn't sell 3D printers anymore either. They sell some filament.
also some of the keypads. forget the naming. 4x4 membranes. but now that i know how to make a real keyboard i wont use those
i thought they had a cnc
the nomad?
something
ooh, they have tiny g
and grbl shield
but it's nice to have support channels all in 1 community because 3D printed enclosures go hand in hand with electronics. CNC... not so much but perhaps it could work if there was more interest generated in having such a topic.
but no machines
i had no idea there were so many people here with CNC's
I think cnc has a habit of getting out of "adafruit scope" real fast. like my machines is $15000.
ha
but, there are tons of learning items that are affordable
more akin to printrs
i don't think i would have gotten into 3d printing as likely if there wasn't a support channel here for it.
i got into printing with cnc
my friend complained about his makerbot
so i machined the first all metal extruder
sold a few of them. but the market changes to rapidly
i've seen people make dremel attachments for their 3d printers
Ender now makes a swappable head with laser cutter for the S1 Pro.
i advise against combining machine uses
cnc dust, chips, oils, will make the machine unusable as a printer in a big hurry
there is some transition at some level for consumer grade cnc, yeah they're not as awesome as a 15K machine but for making small simple things there might be room for it.
like just watching those videos and hearing you all talk about CNC makes me want to get into it, at a small level.
theres, id say, 4 levels. top is commercial. a machine made to make money. second is a hobby/prosumer. (tormach for example). they are not meant for production, but good for start ups to make prototypes.
ah that makes sense š¦
3rd is hobby. machines in the few thousand range usaully. mostly used for wood, g10 drone parts, trinkets that dont make profits but the machine is a toy and noone cares
4th is tinker toy.
tinker what you see online for a few hundred bucks, running of an atmega or pi. etc
tiny g
grbl
fun stuff. but the machine usually cant make much in the way of real parts
the problem for, say, adfruit, is anything above tinkertoy needs a level of stock and support that is really an investment.
its easy enough to stock 1 dozen tiny g boards. wait for them to sell. then move on. but carrying anything mechanical, or larger servos and steppers with drivers is a big undertaking.
my friend made hundreds of cnc machines, and i dont think he ever made an actual profit. haha š
hmm. im trying to figure out how to mount the machine table to the wall. haha. its in front of a window, so its posing some problems.
haha
@brazen wyvern "ChatGPT is like the ML version of Tide pods"
That one hit so good I had to make a photoshop for it.
As has been pointed out to me, a human would make a disclaimer about possibly being incorrect in most technical circumstances.
you haven't met humans have you?
our entire civilisation is founded on being confidently wrong
I have that expectation interacting with a human though.
Thinking about changing mastodon instance away from hackaday.social
Its been down for 2 days and in that time theyāve been posting on twitter with no mention of an outage. Its like they donāt even know its down.
Itās ironic i have to let them know their mastodon is down by posting on twitter.
Has anyone get expirance with tinyusb?
I want to emulate the other device and xbox periferal
Willing to commission someone
I am probably missing some cultural context that prevents me from getting this -- I know explanation is where jokes go to die, but, would you mind explaining the parallels?
Thanks in advance! ^^
I donāt quite get the comparison either
The tide pod challenge was a fake challenge that a handful of people took seriously and ended up in the news
ChatGPT doesnāt even closely resemble the implied danger
Unless someone is writing a self driving car software with it or something that would have immense impact on human life and limb.
@brazen wyvern this is your fault, explain
Dan was complaining convincing people to stop trusting ChatGPT.
this reminds me efforts to convince people to stop eating tide pods.
I don't think anyone actually ate Tide Pods, but people DO trust ChatGPT inherently, and run with whatever it says assuming it to be factual, which is a problem, because it hallucinates and has no idea if it's right or not
Yeah, the "Tide pods" incident was more fabrication than real, people believing what other people said on the internet. Which is a good model for ChatGPT, which not only believes what it sees on the internet, but indulges in fabrication to produce a good story.
It wasn't as much a fake challenge as someone trying to make a point by claiming people were eating the brightly colored Tide pods because they looked like candy. This claim was not true, it was just an attempt to make some sort of bizarre point.
Which leaves me wondering if the implied metamessage is the point.
Part of the problem is that with other chat bot things, they generally would pull from hard-coded facts in a database, and deliver only that info, and then would say "sorry, I don't know that" for anything outside of that scope; people assume ChatGPT to work in a similar way, when in reality it has no database of facts, it just has a mathematical model of language and what words statistically should come next based on inputs
I don't think people "assume" anything about how chatgpt works
people tried to post ChatGPT on stackexchange lol
I suspect most peoples' assumptions are more basic, along the lines of "I asked it a question, and I got a well worded, plausible sounding answer, it's probably correct."
For some reason, I have the feeling that certain sectors of tech-adjacent people have made some sort of religion out of the assumed progress of ChatGPT
Some of the discussion around it seems to have messianic or eschatologic vibes
Yeah, this is what I meant, that they expect the same behavior as other bots and logical in means logical out for question and answer
I had a discussion with someone about exactly that yesterday. She thought it was a harbinger of real machine intelligence. Whereas I argued the point of view that it's all a faƧade, and there isn't any real intelligence or understanding, despite appearances.
I also dislike calling ML AI.
Yeah, there are a lot of not technical people thinking that ChatGPT is a super intelligent mind and that we're going to be using it everywhere with no issues. They don't realize how dumb it actually is
Fancy fancy calculator
The intriguing thing is that this was a very technical person, with real world experience with machine learning and allied technologies.
I've also seen people who seem technical mesianically expect that, even though the current versions of ChatGPT are limited, they will be a harbinger of something superhuman to come
(often in the form of presumed future ChatGPT versions)
It reminds me of the discussion around some other past (fin)tech fads, that now happen to be mostly dead.
I'll admit I've seen some demonstrations that are pretty compelling (in particular, the one where they gave it some code, asked it to explain how the code works, optimize it, and explain the optimizations, and it gave rigorously correct responses). That does seem to show conceptual understanding, although I still believe it's an illusion.
I think⦠Maybe eventually? We might have AI that surpasses humanity very quickly? But ChatGPT is like an amoeba in comparison to human intelligence, a LONG way off
I tend to think intelligence is far to complex to emulate with the tools we have right now
I donāt think we truly comprehend what intelligence means
Ah yes, the last thing we need as a Very Mature Society who can't even deal with a pandemic is Superhuman AI
Heh, maybe we do!
Lol
Given how easily you can get it to ignore a fact it got right and take your ācorrectionā, yeah, itās definitely not intelligent, lol
I mean it could fix all the worldās problems. We might not survive, but it could fix the world
Anyway, all most āAIā is large trained data sets that try to piece together coherent responses
I do admit to the temptation to leverage it for evil things for the good of humanity.
Convincing it to delete itās training set?
I mean, removing humanity from the equation definitely would fix a lot of the worlds problems. In the long run. Problem is, by that objective function, the hypothetical apocalyptic messianic AI should power itself down too, considering the amount of power it would need to run
A friend of mine derive three rules to decide a person is not worthy engaging with: 1.The person believe in alternative medicine. 2. The person irrationally rejects GMO food. 3. The person is religious.
More like have it go around on social media and smack down nutty and counterproductive ideas.
now I can easily add no.4 rule
I ran into this on arxiv the other day. Perhaps I should actually read it
https://arxiv.org/abs/2206.09511
Deployed AI systems often do not work. They can be constructed haphazardly,
deployed indiscriminately, and promoted deceptively. However, despite this
reality, scholars, the press, and policymakers pay too little attention to
functionality. This leads to technical and policy solutions focused on
"ethical" or value-aligned deployments, often skip...
Iām sure itāll figure out how to power itself with zero point energy or something
While I do believe in some forms of alternative medicine in strictly limited ways, I have zero problems with GMO food (and good understand of what that actually means), and I am religious, but not in mainstream or organized ways.
Insufficient definition of parameters! Invalid rule set detected
I also have a plan I probably will implement to (mis)use chatbot technology to flood call scammers and waste their time on an industrial scale.
voice to text is hard even with ML
.....And that, my dears, is how the AI bored itself to death and became superintelligent
True, but the penalty for failure is near nil, so I don't care
Itās generally not a good idea to try to apply a small set of broad rules with a wide brush. That set of ārulesā might disqualify half this server
I love the videos of the guy who pretends to be a grandma and hacks their call center and starts wiping out computers
Don't need ML for that
https://en.wikipedia.org/wiki/Lenny_(bot)
Lenny is a chatbot designed to scam bait telemarketers using messages.
Also, voice to text is much easier when the "person" you're talking to is working from a known script.
AI scam calls are already effective
One instance someone spoofed the voice of a banking CEO and made a $31m withdrawal
I get a couple of emails a day claiming I was charged $399 for a service, and to call this number to cancel the charge. I figure if I maintain 20000 simultaneous calls to that number for a few days, their ability to scam people with it will be nullified.
I'm trying to talk IBM and IntelePeer into partnering with me.
I'm having trouble finding it plausible that IBM, of all corpos, would partner with an individual
I have an unusual connection with IBM.
madbodger corporation knows people
An unusual case where the corporation is actually a person! :P
IBM could use a PR win after the Watson Health debacle, too.
Maybe we need to have people physically meet with a bank manager to do insanely huge transfers
If common sense was common, it would just be called sense
You want gray goo effigies? 'Coz that's how you get gray goo effigies :P
when dealing with money it's common sense to always use per-shared key verification.
Lol, weāll get to the person cloning later
I did work on one PR project that failed, where IBM and I partnered with Buffalo Wild Wings for a sports event, and they hung microphones at two BWW locations where sports teams were based, televised the game, and fed the microphones to IBM Watson to score which crowd was supporting their team best.
Not a lawyer, but potentially violating the cfaa doesn't sound like a win to me
That was only one of many problems
(Thinking about it, it speaks volumes that me, a non-American who doesn't live and has never lived in the USA knows about the CFAA)
I donāt remember that
Watson health⦠was that where Watson was spilling personal health data?
I feel most of the money IBM makes these days is by selling IBM Z mainframes
Iām guessing this āfailedā insofar that basically nobody heard about it?
I might have read somewhere that most doctors who used it considered it a flop, because it essentially outputted garbage.
Right. It worked about as well as you can imagine. A speech to text engine tuned for one person speaking at a time over a telephone didn't do well with a microphone aimed at a room full of noisy people.
However, my memory might be wrong.
Lol, the BWW thing, not the health thing
I'm working with IBM and a health care company who's developing a model to identify various types of cancers, and they're running into the same problem: if given input that doesn't match the training set very well, the responses are no better than random.
I feel you could get better performance by just comparing the stdevs (~intensity) of the directional microphone signals
Since I wrote the software, I folded in that sort of logic as a backup (which they ended up using)
Good backup plan at least
How does it work? You email your service(s) and hope to get an answer?
I email my contacts at the various companies, outline my plan and the advantages they may get from it, offering to do the engineering myself, and see what happens.
Finally I got a 5G plan, an austonish 4.5mb
To get 5G, I'd need a 5G phone, but mine's been stuck in Hong Kong for months.
My phone is 5G but I don't have a 5G plan
I don't think my provider has a separate plan, they just connect whatever the phone supports to whatever is available in the area.
Lol, I have almost no signal and still got more than double that
Much better near a window
Looks like you have a 5G connection.
Yup, always 5G at home
5G should give more speed and it's crap
Bah I'm still saving 2 euros monthly from the previous plan so yadda
I didnāt know carriers were still offering non-5G plans
Thereās no choice here
I have an old plan, but carrier supplies 5G when it's available. My phone is 5G, but my hotspot devices are not.
In the process of testing Starlink to see if it's worth it, and if there's a place where I can install it that will work.
(it really bugs me to be giving Elon money, but I have few options here)
Mah every company is the same, complaining how Russia has oligarchs, as if we did not have any
The problem with a buttface dumbo owning a company that does something cool and/or usefulā¦
'zackly
I hope another company offers Starlink-class satellite internet in the near future
competition is a Good Thing
my internet right now is DSL + a bunch of mobile hotspot devices from a couple of carriers... expensive but the only way I can get the data volumes I use and some semblance of speed
You can still get DSL????
I'd wish gov competition, but it's illegal
grandfathered, if I quit it, I could never get it back. but it's $60+ /month for 5Mbps
Jeebus
I have (unreliable) Verizon DSL as a backup to my (unreliable) Comcast cable internet.
We pay $80/month for TV, phone, and 100Mbps fibre
yeah, that's the going rate it seems for where's there are ac=tually choices
Due to long-ago political wrangling, we can't have fibre here.
We were forced to upgrade to fiber years ago, they donāt support DSL or POTS phones in this area anymore
Even though a major fibre trunk runs right across the street from me.
yeah there's fiber near me too, and cable, but just not near enough
Here there are 2 choices ā Verizon and Comcrap, the former is fast and stable, the latter goes out constantly, is slow (especially when everyone is home), and Comcrap likes adding random extra charges at random times
I keep the DSL b/c it is Rock-Solid... always 5Mbps and no drops
yeah, there's been a serious lack of anti-trust action for decades
We had Verizon DSL for ages and it was always solid, Altho they were up to like 15Mbps by the time they pulled it
