That's one way to look at things :P

What's your favorite MCU?

potent stream

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.

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?

These little heating pads don’t get as hot as I hoped DX

#

They hit like 100F max without touching anything, and don’t seem to draw the full 1A they’re supposed to at 5V

late fulcrum
#

I guess you could sandwich one in insulating material and see if it reaches a higher temperature, but that way lies unintended combustion

delicate stream
#

Not sure why it wouldn’t draw the specified 1A…

late fulcrum
#

It could be a PTC device that self-regulates. If so, it might draw the specified current in a cold enough environment

hmm

tardy badger

#

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

tardy badger

I don’t see why it would be unreasonable to cut a fan/filter hole

rapid geode

yeah

#

plastic may well be fine. im just used to everything being 1/8" steel

#

haha

tardy badger
#

Not sure how large you need

#

That thing is $80 but fairly sizable

rapid geode
#

12x16 x 8-10 inches deep is about right.

#

yeah too shallow

rapid geode
#

you need the back plate, rails, the drive is 6" deep and it needs 2" in front of it

fierce prawn
#

Is the hole enough for a cherry 3 pin switch

rapid geode
#

you need to answer my question first

fierce prawn
#

Its cardboard

rapid geode
#

that was not the question

#

haha

fierce prawn
rapid geode
#

ok. then you need a fairly precise 14mm square hole

#

15mm is too big

fierce prawn
#

Which is 1.56 cm

rapid geode
#

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

rapid geode
#

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

fierce prawn
#

Would super glue hold it more firm

rapid geode
#

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 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

delicate stream
#

Gonna connect to 12V and see if it catches fire chaos

late fulcrum
#

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)

delicate stream
#

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

late fulcrum
#

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.

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.

edgy apex
#

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. šŸ™‚

is mind-reading tech that good yet

raw jasper
#

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

can anyone tell me what cable's being used here to connect the bluefruit circuit board to the tft gizmo display?

tardy badger

The connector on the bottom with the black and red wires is the battery connector

#

It’s just bolted directly to the Bluefruit, the gizmo comes with m3 standoffs soldered to it, so the ā€œcableā€ would be the M3 screws that hold them together.

The 2-pin connector at the bottom of the gizmo is an amplifier output to connect to a speaker. šŸ”Š

  // 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)

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.

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.

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.

#

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

ebon dew
#

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

ebon dew
#

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

fair summit
#

Right, two minutes is typical, so feel free to return another time with something else.

ebon dew
#

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..

static flare
#

Ah, okay

#

cool!

ebon dew
#

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. šŸ˜‰

#

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.

#

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.

#

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.

ebon dew
# brazen wyvern Almost started a fire

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.

ebon dew
raw jasper
#

On the other hand, I may be better at unplugging things when I see smoke :P

ebon dew
#

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.

#

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.

acoustic pawn
#

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

ebon dew
#

@brazen wyvern What board did it happen with?

elfin bridge
# brazen wyvern

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.

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.

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.

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

fair summit
#

have to be afk, but interesting observations

violet parcel
#

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

delicate stream
violet parcel
#

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

Yeah

ebon dew
#

oh i thought the camera moved from left to right afterwards like someone was holding it. yeah that would be dizzying to watch.

rapid geode
#

but the general principle is, faster feed relative to spindle rotation means less rubbing, means less heat

rapid geode
ebon dew
#

cutting vs rubbing, makes sense for friction heat creep on the sidewalls.

rapid geode
#

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.

ebon dew

kinda getting deep into material science and physics at that point.

i'll stick with the bloops from my FDM for now. CNC is a whole different world.

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

rapid geode
#

i sold it, but it seems im getting it back soon. not finalised yet

#

nice

ebon dew
#

we don't have a cnc topic would this stuff normally be in robotics?

rapid geode
#

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?

ebon dew
#

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.

rapid geode
#

yeah. a cnc and a printer are virtually identical machines

ebon dew
#

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...

rapid geode
#

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

#

šŸ˜›

ebon dew
#

well they sell stepper motors and stuff to make your own. i suppose that would just fit under robotics.

rapid geode
#

yeah

#

i have the ipad displayport kit meant for this machine

ebon dew
#

Adafruit doesn't sell 3D printers anymore either. They sell some filament.

rapid geode
#

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

ebon dew
#

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.

rapid geode
#

but no machines

ebon dew
#

i had no idea there were so many people here with CNC's

rapid geode
#

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

ebon dew
#

i don't think i would have gotten into 3d printing as likely if there wasn't a support channel here for it.

rapid geode
#

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

ebon dew
#

i've seen people make dremel attachments for their 3d printers

#

Ender now makes a swappable head with laser cutter for the S1 Pro.

rapid geode
#

i advise against combining machine uses

#

cnc dust, chips, oils, will make the machine unusable as a printer in a big hurry

ebon dew
#

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.

rapid geode
#

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.

rapid geode
#

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 šŸ˜›

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.

The tide pod challenge was a fake challenge that a handful of people took seriously and ended up in the news

#

ChatGPT doesn’t 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

brazen wyvern
#

Dan was complaining convincing people to stop trusting ChatGPT.

#

this reminds me efforts to convince people to stop eating tide pods.

delicate stream
#

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

late fulcrum
#

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.

delicate stream
#

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

raw jasper
#

I don't think people "assume" anything about how chatgpt works

brazen wyvern
#

people tried to post ChatGPT on stackexchange lol

late fulcrum
#

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."

raw jasper
#

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

delicate stream
late fulcrum
#

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.

The intriguing thing is that this was a very technical person, with real world experience with machine learning and allied technologies.

#

It reminds me of the discussion around some other past (fin)tech fads, that now happen to be mostly dead.

late fulcrum
#

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 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.
