I picked one up just to play with WLED, never done that yet. Erin St. Blaine has a lot of great WLED learn guides.

[waxen bough]

ESP has TWAI (aka CAN) built in, but does this board have the needed pins brought out? Then just attach a CAN level converter (https://www.adafruit.com/product/5708) , instead of i2c->MCP2515 type board.

[vagrant flax]

I would recommend coupling it with the Neopixel BFF driver if you're going to use WLED

[sand lotus]

It shows circuit python in that learn guide in JP's stream but that section does not show up for me in that learn guide...

[vagrant flax]

It will let you draw up to 2 amps for your LEDs without stressing the QT Py's regulator

[vagrant flax]

(and you get a handy JST port for your strip)

[sand lotus]

Maybe only JP has access to some new learn guide where it's included...

[sand lotus]

Good enclosure design. 👍

In the case of the Pico, you'd need something like that if you want to get to the bootloader while plugging it in.

Use a 3D printer for Hot Glue molds... 😉

[lavish patrol]

Hot glue comes in different colors...

You can also get hot glue with glitter in it.

[sand lotus]

Use painters tape and you can fill a hole with hot glue flush, no shaving or sanding needed. It will provide a nice flat surface. Trick from automotive world to DIY your own custom silicone seals.

Good for waterproofing things except 3D prints aren't really waterproof anyway.

Looks like it fits great, like how the headband has a nice outer angle. Did you have to measure your head for that one?

[upbeat coral]

@lavish patrol 👍

[sand lotus]

roll the xacto knife between your thumb and wire. yes you can cut yourself but it's definitely better than shaving the jacket. shaving will definitely cut some of the threadlike wires. rolling between your thumb gives you a better shot at keeping all the wires.

SD card reader and then read only read the card slots ux on small screen what fit on the storagebox cover and only show when it is opened

[vagrant flax]

I took next friday off for Zelda too 😄

[sand lotus]

That's a neat idea. Add switches like a switched hub so you can enable SD cards from a bay.

[upbeat coral]

Attach hinge to accordian style platform inside so that cards in back come up when henge opens

[sand lotus]

Just plug in the entire box and enable the card you want to use via a micro switch.

[shell mason]

Djedevon so hinge could hide wire to screen for example

[sand lotus]

I might try to do that for a special remix. Definitely going to do a community make on that one though.

Have you ever tried using a 3D pen to fill in gaps? I've been thinking about getting one for that purpose.

So might as well just use a soldering iron with some filament..

yeah, RAL would be nice, but the color palette isn't as rich, couldn't find an exact match for the PowerBook grey… (well, the most common, there are like 5 of them)

[sand lotus]

I just post something obviously wrong in discord. People are faster to correct you with the right answer than answering an open ended question most times. Life hack.

[gray obsidian]

I wonder if they'd come and desolder our LEDs if we stopped paying the fees… just like with Photoshop

[mellow arrow]

Indeed. My core code base does self calibration during the smoketest and writes the settings to EEPROM so each board is pre-tuned.

[slow spire]

This is how we feed the AI. 🙂

oh yeah the spelling of "secresy" is old timey

[brazen grove]

that's called "small caps"

[brisk bone]

Hi, joined a bit late, but thanks to 2x I am already "up to date" 😛

[open surge]

peripheral

[brisk bone]

No, no templating yet, but you can expose api and use it from JS

[upper sandal]

oh you don't need jQuery honnestly

[brisk bone]

During my testing prints were the thing that mostly increased execution time

[upper sandal]

I like jQuery, but document.getElementById and fetch are all I use in my http examples

[brisk bone]

I personally prefer document.querySelector, seems more verbose and is pretty much the same an jQuery $()

[upper sandal]

oh yeah that's good too

[brisk bone]

In NeoPixel example

[brazen chasm]

👋🇸🇪

[upper sandal]

in my example code I wrap the handlers in that:

from adafruit_httpserver.status import CommonHTTPStatus
ERROR400 = CommonHTTPStatus.BAD_REQUEST_400

@server.route("/receive", method="POST")
def receive(request):
    try:
        body = json.loads(request.body)
        # do the things
        #
    except Exception as err:
        # show the error if something went wrong
        traceback.print_exception(err)
        with HTTPResponse(request, status=ERROR400) as response:
            response.send("error")

[brisk bone]

I pushed fix for the problem with methods = [POST], the way you did it first time should have worked

Also "segments_keys" in line 65?

[upper sandal]

window.print = console.log

I actually do that in my electron app. I also do all my javascript without semi-colons anymore.
That way switching with python is less painful

[strong acorn]

not python with semicolons? :p

[upper sandal]

I mean... you can

[strong acorn]

I use semicolons in python when I want a convenient sequence of statements in a cut-and-paste REPL one-liner

[upper sandal]

yeah, though the REPL takes returns quite well too

[brisk bone]

It is easy, a parameter for Response constructor

You also have common statuses that you can import in status.py

[upper sandal]

@brisk bone have you thought of something like:

@server.onerror(404)
def handle_404(request):
    ...

to handle errors when they happen outside of a handler (404 in particular when serving static files) or when a handler errors (like a 500 error ?)

[brisk bone]

status=400 won't work, status=BAD_REQUEST_400

[upper sandal]

yeah I did that to respond with an error (I don't need a ERROR400 variable, but it's easier to look at in the rest of the code)

from adafruit_httpserver.status import CommonHTTPStatus
ERROR400 = CommonHTTPStatus.BAD_REQUEST_400

[brisk bone]

yes I was considering that, the problem is that the server does not control responses, and thus is not aware of them, this is due to the chunked response

[brisk bone]

After merging this PR there will be no CommonHTTPStatus but separate Status objects, saving typing

[upper sandal]

and I'll have to update all of my examples to 4.0.0 😛

[brisk bone]

although arguably it might be possible to define custom handlers for errors outside handlers

[upper sandal]

ah I remember the old days when HTML was constantly SHOUTING, I find it exhausting just thinking about it 😉

[left pier]

And blinking and scrolling ...

[upper sandal]

we can plug a handler when catching FileNotExistsError and InvalidPathError (and AuthenticationError)

[brisk bone]

I looked how Flask does it, and it returns a Response, but if you pass a generator as a body it uses chunked encoding, seems logical, but it is more advanced and requires some more knowledge and understanding of Python

[left pier]

Very cool, looks a lot like building WLED in CP.

Good morning ☕

I watched the video from yesterday with the ip connected form to the matrix thingy.

[inner spade]

Hello! ☕️☕️

[sand lotus]

i think the most basic example, at least what i was going for the first time i ever ran http server, was to display temperature from an I2C sensor.

I remember something like that for the original Arduino LCD character display where you could click on dots and download a pre-built sketch.

no idea what website had that available, it was a really nice thing to have available.

WLED is very new comparitively to an Arduino. I have yet to play with it but it does look really cool.

Erin St Blaine uses WLED a lot to beautiful effects.

I don't know what the requirement is but I know it'll run on the original ESP32 or Adafruit's ESP32-V2, non-circuit python.

So you can repurpose them for either WipperSnapper or WLED projects.

Sanitizing variables is very important. Anything outside the bounds of explicit POST attributes should be filtered out to not respond. I know it's just local but having basic security procedures in place will help prevent someone from putting it online and getting shredded.

Well not respond in a way that will allow some kind of injections.

I did see something recent about security related stuff with http server. Someone came in and helped prevent it which was a huge relief to see.

Yeah, GJ MichaelPokusa 👍 Glad someone's got an eye on helping with the basic security because it is after all a server. Even if it's just local it's still a good idea not to be completely naked.

periphery is one that gets me all the time.

i'm really bad at math. did you hear about my PCB screw up?

input the diameter as the radius and ended up with a 19" ring light instead of a 9.5" ring light.

it's huge

pay attention in school kids, you don't want to grow up being bad at math.

[inner spade]

Happy accident? Now you have an excellent camera ring light.

[sand lotus]

already got some stuff coming to turn it into an illuminated lazy susan.

How's the VCO project coming along?

It's pretty much always been width/height since TV's first came out I think. 480p is 640x480 not 480x640 😉

[inner spade]

The revised PCBs are still on a national tour, shipping wise. They come from OSH Park just a 2.5 hour drive from here but the USPS decided to route them three states away.

VCO code is mostly done, just need to tune rotozoom somehow to save memory.

[sand lotus]

It happens sometimes. Distribution centers are weird like that.

like a rotoscope, on a microcontroller?

the teensy is deceptively powerful for its size though

[inner spade]

It would be faster to rent a drop box in Portland and drive there. It’s a beautiful trip past beaucoup waterfalls and such.

[sand lotus]

oof a function with embedded td's.. and this is going to be a basic example? i feel like a beginner is going to look at that and have their eyes glaze over.

depending on how much you order from OSHPark... sounds like you've already thought that one through. it does sound quite practical to prevent stuff from going 3 states away.

would it be practical to start setting up a stylesheet?

oh derp you already have one. why embed it when you can throw them into css

ah ok, yes it's definitely advanced.

sometimes you have to throw it all into the script to get it working before you can start splitting everything out. it's all part of the process.

get it to work first, pretty comes later.

color pickers are generally 2 clicks. first is color then saturation.

you said it was for advanced users and advanced users usually go for the dark themed.

exactly, because eye fatigue.

it's attached to the TR somehow, tr outline?

lol i feel the same way whenever working with tr and td's

and you get everything looking beautiful, perfect... and then load it in another browser and it looks like something from the 1990's

because html is standardized but also all browser manufactures have their own "interpretation" of the standards.

like web serial. chrome is like yey this is cool. Mozilla is like, hard no we're not doing web serial.

take a screenshot, zoom in with gimp 😉

[inner spade]

Is there a way to update the grid elements with the current color value ?

Yes

Thinking about input from multiple tabs and devices.

Would need a manual update button (snapshot)

[sand lotus]

mqtt broker sounds the most compatible method

that's a good idea

things would complicated real quick with web sockets

good session, looking good so far. looking forward to more.

@unkempt shoal the original bus pirate did not (we think) but we could add it to our since circuitpython supports it!

Can always correct silkscreens with notices in product page and especially pretty pins doc. I use pretty pins for every board as my main reference.

Hello

Good afternoon.

[inner spade]

👋

[cinder wind]

I've always wanted to try one of these flexible HUB75 panels with a MatrixPortal https://amzn.to/3VL745f

[inner spade]

I’ll need 16 for a matrix of portals.

[wind spoke]

I am wondering how much power hungry those matrix are, and if you want to power let's say 128x128 pixels, would it be possible to pump enough from a USB-C or there could be a version that request more power with Power Delivery?

[cinder wind]

4A per panel when full on I think. pretty hungry, but yeah you can power them at reduced brightness from USB

[random sand]

So four panels giving you 128x64?

[silent anvil]

It's pronounced "jif"

[wind spoke]

Go for 64x64 panels so that 4 make 128x128.
Also as said, you need to solder two pads to have the additional address for 64 high panels. (it is documented on the learn guide).

[cinder wind]

RIP Twitter API

[wind spoke]

Also, if you want multiple panel, try to order them simultaneously to have more chance to have the same "colour".

128x128 is pico8 resolution... 🙂

[viral sail]

Thanks @haughty quiver

[open surge]

thanks JP!

[inner spade]

Thanks!

[waxen bough]

I don't have a project for it, so though the controller discount is nice, the panels themselves are still out of my "playtime" budget.

[random sand]

Thanks JP, I've ordered parts for three different projects but I'll use this one first to learn CircuitPython.

Hi N&P

What would be preferable, conductive thread of mini wires like these ones?

BTW, yesterday I did a refresh of the sound reactive drum set you folks made with a gemma and a mic, but with a circuitplayground.
This is a proof of concept to show it to the folks from a marching band, and we are probably going to put some lights on the band, with esp32-c3 qt's and the new espnow code.

And yeah, we sowing clases in high school here in Costa Rica, so those skills are pretty common here.

[unreal bay]

try the backing paper from sticky-tape or adhesive labels, it works well for creating smooth surfaces, safely mashed with your finger/tool

didn't do it for lenses, more for home made connector strengthening. good for epoxy as well as hot-glue

[sand lotus]

Making a sound reactive project with a gemma is an accomplishment in itself. Gemma's and Flora's are awesome for wearable projects but the Gemma can run Circuit Python.

[gusty wedge]

This video synth is amazing.

And so ephemeral!

Factory footage or MTV music video from 1995.....

[prime sentinel]

I'm doing it the hard way with an Arduino

[waxen thistle]

There are three different major versions of the Speak n' Spell....

The original with physical buttons.

After that is one that looks like that one, with the soft touch buttons. This had several iterations through the 80s and early 90s.

And recently (as in the last few years), they re-released it -- avoid that one as the LCD is very dim, the case is flimsy, etc

[nova totem]

Real weather is better but does the palette GIF work? Maybe still short.

[tulip canyon]

[sand lotus]

very satisfying

[pseudo lotus]

yeah I think I saw that they had re-released them, but I've not cracked one open. I assume everything has been boiled down to one tiny board now

I liked the old 7 segment displays ones

[proven crow]

Q for the show: Would the RTS line of a CH340 connect directly to RESET on an ATtiny? Or would something else need to go in between? Also, is a pull up resistor required?

It's funny to remember that the screensavers used to be in a retail box on the shelf...

I wonder if you could swap out the built in screensavers from a Roku or something

I was wondering if the can BUS card
can talk to an OBD II port on a car

[robust horizon]

(i2s, oops)

[vagrant flax]

I can't wait for the prop feather!

Is there an ETA for it?

[delicate fractal]

when microcontroller boards say they have, for example, 3 UARTs, does that mean they can do 1.5 bi-directional serial ports? or 3 of them?

[robust horizon]

@delicate fractal usually a UART is a receive + send

[prime sentinel]

UART stands for "universal asynchronous receiver/transmitter" so yes, both directions

[delicate fractal]

RT. I was not thinking about the acronym. duh.

[slow spire]

@open girder How many watts might that QtPY I2S amp be? It sounds great!

Q: Newbie question here but I've played with i2c sensors with Circuit Python, but I understand physical distance is an issue. What would you recommend a newbie look into for reading sensors or controlling things around a body-sized object (i.e. cosplay / human sized props)?

good afternoon folks

[lavish patrol]

Morning/afternoon/evening all.

[haughty quiver]

hello!

[inner spade]

Hello!

[verbal river]

Today I am editing documentation for my hobby project. What has my life become? 🤦‍♂️

[charred lion]

Hello

[lavish patrol]

And of course, topical...

[dusk socket]

great day to learn something

[haughty quiver]

hahaha

[clever summit]

Good Evening JP

[lavish patrol]

Good evening. @clever summit

[clever summit]

🇸🇪 👋

[verbal river]

oh wait today is about envelopes? I may have to stop editing and pay attention.

[ivory flax]

Hi John hope you have a great show today. I need it.

[sand lotus]

Good afternoon

[charred lion]

I'm trying to expand on JP's "Split Ortho Keyboard with TCA8418 Matrix Expanders" project.
What I want to do is create a eight(8) Row by thirty-two(32) Column Ortholinear Keyboard.
My idea is to create four(4) modules of eight(8) Rows by eight(8) Columns.
Each of these modules would be monitored by a TCA8418.
Then these TCA8418s would be connected to a PCA9548 I²C multiplexer.
Then connect the PCA9548 to a RP2040 I²C port. I should be able to almost use JP's code unmodified to make it work.
I want to use one I²C port for keyboard input and use the other I²C port or SPI to run some displays. Maybe a PC Status Monitor built in to the keyboard?

[lavish patrol]

Modulate/demodulate...

[sand lotus]

the new ring effect jepler added will come in handy someday i'm sure.

Sounds like a cool project Evil Dave. Don't forget to add a computer help button.

Thought it was cool the lego's perfectly matched up as an enclosure for it.

The 720p does kinda make me squint to look at the code shared on the screen.

[lavish patrol]

Noice.

[charred lion]

My keyboard layout is designed for Peel & Pook typists. The Alpha pad would be a 5×5 grid plus the Z underneath that.

[sand lotus]

looks like the LCD library has some very helpful built in functions that does most of the things people would want.

[inner spade]

Those displays are handy. Can get a simple project up and running in short order with a character display.

[sand lotus]

Any idea how many of those you could chain via stemma on 3.3V power even with a multiplexer without requiring an external power supply?

Thinking they might be fun to chain a bunch of them.

[charred lion]

I bought 10 of those PCA9548s so I guess I could try some time in the future

[sand lotus]

Don't need to buy right angle pins, those pins are long enough to bend. put it in a metal brake and just bend them yourself. perhaps a vice so they're all symmetrically bent.

[inner spade]

https://www.digikey.com/en/products/detail/cw-industries/CWR-130-24-0203/1122541

[sand lotus]

@charred lion The PCA9548's really are great and super easy to work with once you figure out how. They're awesome multiplexers.

[inner spade]

Nice mix balance with both mics

[lavish patrol]

Can hear bleeps, bloops and John. 👍

[verbal river]

yes 🎶

[sand lotus]

Yes can hear you and the audio nicely.

[charred lion]

I plan on hanging one on each of the RP2040 I²C ports for my keyboard design

[sand lotus]

Instrument out could be a tad louder.

ah there we go, good to go

Being able to see the envelope is a great way to learn/teach how ADSR works.

[verbal river]

uh-oh I may have to add envelope pics to the patch editor for my FM synth module #blameJP

[split gazelle]

This is an excellent explainer on envelopes

[sand lotus]

If you attack at the same time you compress every other instrument that's how you get really hard hits.

[charred lion]

I just wish there was an easy way to have two(2) RP2040s as slaves to a master RP2040.
I guess I could use a RPi Zero as the master to two RP2040 slaves.

[cinder wind]

what did I miss? is anything on fire yet?

[verbal river]

Yes, JP is on fire!

[cinder wind]

if the two secondary RP2040s don't have to send anything back, you can use standard serial (main TX-> secondary1 RX, secondary2 RX) and that can be really fast

[verbal river]

I have a PC app sending commands to an RP2040 over a USB serial connection. Not sure it qualifies as "easy"...

[charred lion]

Well one RP2040 would be sending keyboard input and the other would be controlling any displays built in to it.

[sand lotus]

Awesome synthesizer plus tiny speakers = sad panda noises.

[charred lion]

If I could easily use RP2040s as slaves, imagine a keyboard where multiple parts are handled by different RP2040s

[verbal river]

I think you could do that with a UART connection without much trouble

[cinder wind]

yep

[sand lotus]

After seeing all the DVI projects got me thinking about a quad RP2040 for video output to get it up to higher resolutions. Not sure how it would all mux together though.

There's so much power on the Metro M7 though, there's gotta be a way to plug into its higher clock for higher power stuff?

[inner spade]

Sound was okay.

[verbal river]

Yes I could hear that OK

[lavish patrol]

This project has struck a chord...

[charred lion]

If you could slave the RP2040s using I²C then a PCA9548 multiplexer.

[sand lotus]

An iMX for synthesizer has me really excited.

[inner spade]

synth sound mic is a little hot compared to lav mic

[sand lotus]

that sounds great

[inner spade]

portamento versus bending

[charred lion]

I wonder if you could stack multiple RP2040 feathers and have each one handling different parts of a 100% keyboard.

[sand lotus]

Does synthIO have all the chords you guys were working on with the euclidian chords etc..? Would love to have a way to easily tie into chords.

[vivid ore]

Isn’t that all of the hassle of managing multiple MCUs with none of the advantages?

[charred lion]

I like the idea of using CircuitPhython to program a 100% keyboard but there are just not enough GPIOs on the pico

[lavish patrol]

Can't see it, @haughty quiver 🤔

[vivid ore]

Technically there are if you forego everything else and get creative with the key matrix layout

[charred lion]

I'm more of a "take a existing project and mutate it" type of builder. Some of my best software solutions were accomplished that way.

Retired custom software designer but I worked mostly in the 80s & 90s.

[vivid ore]

I have a preliminary design for it that I never had made, but it had the full 104 keys with 21 gpio iirc

I tried to squeeze it into a 2-layer board, but the routing got REAL funky.

[charred lion]

All I need is for someone to post a design for a RP2040 based 100% keyboard and then I should be able to expand that to my 8×32 Ortho keyboard

[vivid ore]

Oh, that is a lot more keys than a full size though

[cinder wind]

hey @haughty quiver I think the matrix mod is being covered up by your head

[charred lion]

I posted earlier a possible way to do it but I'm not sure if I²C could work for it.

[vivid ore]

Ah, there are ways to do it, but circuitpython’s native key matrix module doesn’t support using expanders in matrices.

[sand lotus]

and voila we have ring modulation

[cinder wind]

keypad does support shift registers (74HC165 etc) but that's about it as far as external expanders

[vivid ore]

In a matrix layout, or only for individual keys?

[cinder wind]

shift registers are one way: out -> in (8 parallel inputs to 1 serial output), so no matrix there

[sand lotus]

ha sounds like azzido da bass, dooms night 😉

[charred lion]

My idea for a 8×32 keyboard is to create four(4) modules of eight(8) Rows by eight(8) Columns.
Each of these modules would be monitored by a TCA8418.
Then these TCA8418s would be connected to a PCA9548 I²C multiplexer.
Then connect the PCA9548 to a RP2040 I²C port.

[verbal river]

"save frequently" - wisdom for the ages

[cinder wind]

I put up a few quick examples of using the new synthio stuff here:

[sand lotus]

Here's dooms night. one of many iconic EDM songs from the early 2000's. a great example of bass synthesis. https://www.youtube.com/watch?v=3cYwggM2UGk

very nice todbot, sounds great for synthwave resurgence for sure.

[lavish patrol]

Almost sounds like it's being played backwards.

[cinder wind]

yeah thanks!, pretty impressive what we can do with just a handful of lines of code

[sand lotus]

yes if attack is long and curved it can sound that way

your handful lines of code are much different than my handful 😉 you, JP, and Liz are so much more advanced than I think any of you give yourselves credit for.

by that i mean far more advanced than myself and most for midi and audio coding. waveform coding is not easy. there's a lot of math involved.

[cinder wind]

yeah the math is frustrating to get your head around. a lot of times I just "cargo cult" it, blindly copying around stuff until it works. hahaha, and then eventually a little understanding happens

[verbal river]

The math is the best part! 😄

[lavish patrol]

This has been fun. 😀

[inner spade]

Amazing progress on the audio/video synths for the M7. Can only imagine what's next.

[cinder wind]

yep, been doing everything on RP2040. It's an M0-class part, so if it can run on it, it'll run on anything better

[sand lotus]

Synthesizers are awesome. Thank you JP for the excellent bleeps and bloops!

[lavish patrol]

Thanks, @haughty quiver 😀

[viral sail]

oh @cinder wind the font I use in my weather station is called "Good Times". The numbers are particularly futuristic looking.

on par with the Nasalization font

[cinder wind]

it's really good

[sand lotus]

I have a 120, 80, and 16 BDF of it if you're interested.

[cinder wind]

very cyber 80s

[sand lotus]

the one i used in the dvi demo is the 16, it scales pretty well.

though with the DVI there's no font that will upscale that drastically without looking blocky

[lilac tusk]

Hello first week in a while that I haven’t worked OT

[sand lotus]

Well you missed an awesome episode if you like synthesizers. Definitely worth watching the YT video, some great lessons on basic synthesizer usage.

[lilac tusk]

Gonna give it a watch this evening

[sand lotus]

The synthIO stuff is going to be amazing, no doubt in my mind.

[sand lotus]

Good evening

[pseudo lotus]

first time catching this stream. I may have to break for a bit for food, how long does it usually run?

I got to submit a couple of those 🙂

It was a lot of fun - Adafruit folks ran really good sprints

[clear matrix]

@pseudo lotus Hello! Thank you for participating. It was successful because of folks' contributions. It was also nice to chat with you in general. 🙂

[pseudo lotus]

Thanks, and thanks for putting up with my peppering of random questions about potential projects 😆

[clear matrix]

Completely worth it. 😄

[pseudo lotus]

Gotta go for a bit, but hope to catch the tail end of the stream. This is an interesting format!

[sand lotus]

Feathers use an LDO for power switching. #help-with-hw would be a good place for that question.

[inner spade]

Generally speaking and when using properly rated batteries and other power sources, Feathers choose the higher voltage source.

[sand lotus]

Pi’s definitely require 2FA to purchase still.

[unreal bay]

Pimoroni have 4gb in stock with international shipping

they dropped at 6pm today

4hrs ago

[sand lotus]

Pimoroni is a good place because Pi’s are British and so is Pimoroni.

If you’re in the US just be prepared for long shipping delays. I got one from them and it took 31 days to arrive.

[brazen grove]

when a function can return a list or nothing, I like to return an empty list instead of None

it still counts as false, but you can iterate over it

[inner spade]

That’s an excellent approach. Thank you.

i was a sinner, and didn't have pre-commit setup

[brazen grove]

[unreal bay]

string formatting with args

failed with no args

i think it wanted %s and i was using "".format() instead, or i wasn't but the sensirion library using python logging was doing that via logger.debug("gibberish".format(nothing))

like this line:
https://github.com/Sensirion/python-i2c-driver/blob/master/sensirion_i2c_driver/connection.py#L143

log.debug("I2cConnection received raw: {}".format(
self._data_to_log_string(result))) # with no result

empty byte array response for i2c command, but not necessarily meant to be

[brazen grove]

the args is an empty list when you pass no args

[unreal bay]

maybe it was the empty list rather than none as you say

thank you! unblocks me for the SEN55 dust sensor

[modern night]

oh that is one fully packed sensor

[unreal bay]

go with the 54 instead, save a quid or two, but had to try them all. (Ikea went with 54, PM+RH/T+VOC, 55 includes NOx)

using twilio for number masking, and sms forwarding. TwiML. Clever. With DynDns your esp32 could respond in some chatgpt manner to a phonecall

You must have seen wippersnapper / adafruit IO adding sms in/out

[modern night]

Good to know. I went with this build: http://www.adafruit.com/wishlists/561851 for my home but have been interested in what else is out there

Twilio is something I'd like to know more about, but it isn't something I've had time to look into

[unreal bay]

add in the scd4x series and you get CO2 for concentration or agri-related. yeah nox=nitrous-oxides. And IO does take inbound SMS feed msgs(pro plan)

or to trigger an action

In the US, you can also send text messages to your phone's email addresses. So if you can send an email from your program, that target the email goes to can be your phone

[modern night]

What hobby circuit python projects have you been playing with lately? (I've been out of the loop 😅 )

Oh very nice! I'll need to go through the vods to catch up on it. That looks like it's got a lot of components I'm interested in

I feel that carting before the horse. I need to fix my environment sensors so the data they record is stored in an easy to use database, but I keep trying to figure out what database before I really know what I need that data for

That color selector for the grid is one of the parts I want to try and use in my home server. That rest api would be cool to see

[smoky island]

https://coloris.js.org/

[unreal bay]

was wanting somewhere to chuck endless data at high rates, not crazy rates, and only show the last 60days or whatever like adafruit do, but long term cold storage for all data past the 60day window (slow to retreive, cheap to store). Also cheap but also ideally backed up. Know anywhere or do I really have to build the project I dont want to?

[modern night]

Sweet! Thank you! I'll explore that (soon ™️ )

[unreal bay]

Thanks @smoky island for everything

[modern night]

My server is completely local, so I don't know about remote servers to manage that unfortunately

Have a good night, thanks for the stream!

[unreal bay]

mosquitto with client doing the backups probably. cheapest 🙂

[modern night]

That does seem like a reliable way to do it that lots of other folks have tried! (I'm just not that familiar with much in that world). If you find one you like that works for you I hope you share your experience! I'm always excited to learn about that world

[smoky island]

About to get started for the morning. Going to work on a REST API for controlling neopixels and dotstars. You can follow along on YT: https://www.youtube.com/watch?v=_GHADsjf2J0 or Twitch: https://www.twitch.tv/foamyguy_twitch

[sand lotus]

Good morning ☕

Went back and watched the beginning of the stream real quick. I'm not sure what REST API is. I don't think I've ever used it. Is it a specific protocol, type of coding, or a framework?

[upper sandal]

it's a HTTP state-less API

as opposed to one that uses a session or a continued connection

[sand lotus]

I just consider them all API's regardless of what protocols or states they use. An API is an API to me. 🤷‍♂️

[upper sandal]

so everytime you trigger or get a thing with a crafted URL, is typically a REST API

[sand lotus]

Something like MQTT I do consider kind of stateful and I use it differently than just get/post http.

ah, I'm used to being an API user instead of creating the actual API. guess there's a difference for the developer creating the API from that perspective.

[upper sandal]

yeah MQTT is clearly not REST

I mean, like everything else there's flexibility in the meaning, I'm not sure if retrieving a time-limited cookie to open a session is still considered REST formally speaking but, you know, it's just words 😉

[sand lotus]

REST uses sessions and cookies?

[upper sandal]

I think the point is that it doesn't

[sand lotus]

so rest is stateless? yeah the semantics of it is confusing sorry. that's why anything called API i treat the same and just figure out a way to work with it.

[upper sandal]

like if you use it by using request on URLs like that, it's typical REST:
http://somedomain/api/{token}/get_list/{listname}
http://somedomain/api/{token}/remove_list/{listname}

[sand lotus]

ah, then most of the stuff i work with is REST lol

good to know

[upper sandal]

yeah

[sand lotus]

might be easier to associate REST with "REqueST"

[upper sandal]

doesn't matter if it uses the URL or header to pass data, that's an implementation detail for the HTTP version, what matters is that each request is technically independent, which makes it much easier to use [than most alternatives], since there's no need for a complex client, using sockets or anything, just call URLs.
So like, a shell script (or a human) using curl can use a REST API

but on the other hand, it's purely client initiated, so there's no getting "push notifications" from the server

hence the need for MQTT or websockets

(or another example, a html form can use a REST API also)

[sand lotus]

I do like curl/get/post. it's super simple to work with most times. no framework needed... however stuff like MQTT does have benefits with built-in buffering to ensure everything goes through.

yes exactly

[inner spade]

G’mornin’ ☕ . Getting a late start here.

[sand lotus]

just tell people they can't have a space. most people are used to required underscores or hyphens instead.

that's going to be a long list of colors

filling with 0 then it won't have memory of last state before power off? maybe a text file with last known values?

[upper sandal]

yeah neopixels don't turn off when the code stops

[inner spade]

Neopixel colors can be set like list elements: pixel[0] = 0x020303 —can the object be read/sliced like a list to read values?

[upper sandal]

if you want to save the state (it can be another API call) you can use NVM, it can definitely fit a neopixel strip buffer

[upper sandal]

yep

but you can not read the pixels, they don't have a bidirectional protocol, you can only read the buffer of what you sent

[sand lotus]

true, if you're running a marque script it'll run again. i'm thinking more of a way to keep a custom pixel art shape like heart without having to re-program it?

i guess that starts getting into some kind of image load almost

[inner spade]

Like in a bitmap image format

[sand lotus]

that's a good idea. depending on the matrix size just treat them as pixels and save to bmp

i mean they're called neopixels so why not

not sure how big of a script you want or the use case but bitmap_saver already has a nice record function in it.
