I usually use just whatever a product's guide indicates, but is there a particular reason to use I2C over SPI or vice versa?

[cinder wind]

mmm organic compounds

[shell mason]

Lax gas so john need to check gas levels

[inner spade]

SPI: higher data rates, more wires. I2C: fewer wires, gotta know device addresses.

[sand lotus]

Could you use this as a crude breathalyzer?

[teal river]

JP will be safer from Lars gas attacks when this is working

[sand lotus]

That's a good question... is it methane sensitive... for science?

[shell mason]

JP totally feel safer now when MOX Gas sensor is working from Lars gas attacks

[cinder wind]

I think so? It says it measures VOCs and alcohol is a VOC

[teal river]

What's eCO2 specifically vs. CO2?

[cinder wind]

hey @haughty quiver, get drunk for science!

[teal river]

Those paint markers are pretty noxious!

[cinder wind]

datasheet says "eCO2 = equivalent CO2 values for compatibility with HVAC ventilation standards"

[teal river]

Ahh, danke

❓ does it need to be calibrated in some way?

[shell mason]

[teal river]

Voltaic is fun to say

[sand lotus]

It works best when used in conjunction with a temp/humidity sensor MikeP.

"Every room gets a fart monitor!"

[sand lotus]

hmm would this be good for monitoring a 3D printer somehow?

[waxen bough]

Solder vapor fan control? (or 3d printer hood?)

[sand lotus]

i guess the biggest concern would be a hotend melting so a temp sensor IOT probably more useful.

[teal river]

I suppose you could have it outside of an enclosure to tell you if there's a leak from ABS fumes I think? Pretty sure it would detect that

Good show JP!

[cinder wind]

JP is the biggest consumer of StemmaQT cables, and he uses them as picture hangers

[dry marten]

I just dunno if I would bother with the sensor in the enclosure, as you can pretty safely assume that if the printer is running, you're getting fumes

i've got the files downloaded to print this afternoon

[open surge]

I printed one of the enclosures this morning, works great with the v1 too

[teal river]

Ohhh, switch!!!

[sand lotus]

i love the new rate switch

[teal river]

I had put switches on mine, but pre-soldered switch is good!

[sand lotus]

i got 3 of them and 1 of the older style. the switch definitely very very convenient

i use multiple of them for all the batteries in my dragon mask. i needed a lot of little chargers, they're perfect for it.

[teal river]

I got like 20 of the old ones XD

[sand lotus]

got more than needed though because i didn't realize the BFF battery plug was also a recharger. so the qt py has one built in if you get the bff charger.

[teal river]

I have a bunch sitting in a little drawer when I lose or break one XD

I had one that I damaged the USB part so it was nice to have extras

[sand lotus]

the 259 charger also has pass through so you can use the load on usb while you charge it, kinda like a feather charger circuit. the little lipo chargers don't have pass through because it plugs directly into usb.

[teal river]

Pro tip: do not drop laptop while the USB charger is plugged in

[shell mason]

[shell mason]

https://tenor.com/view/residents-torch-gif-19274916

[sand lotus]

the ender S1 pro recommends 1.75mm filament. i see there are slightly larger filament like 2.2mm or something. is there is any scenario where it's possible to use the larger filament or is that specifically for different printers with bigger nozzles?

ohh looks like the sceptre i made

3D printers generally make everything fun

[rocky reef]

https://www.thingiverse.com/make:1063457 - led neon sign

[sand lotus]

that's one heck of a nice torch

[teal river]

It does depend on the printer. A printer marked 1.75 can NOT do 3MM because it just can't fit; but some printers can do multiple sizes

[sand lotus]

ah makes sense, the filament won't even fit through the extruder gears derp.

[tulip canyon]

Thanks everyone, great projects all

[nova totem]

Nice projects everyone

[hard hollow]

Great projects tonight folks!

[proven crow]

Thanks! There's 8 motors, same as last time

[sand lotus]

i was trying to hurry up and finish a project. got it done and joined just as they were shutting it down. 😦

[robust horizon]

bring more 5x5 projects next week y'all! we'd love to see your stuff. don't be shy.

darn @sand lotus now you have to go a whole week without breaking it by adding one more feature 🤣

[sand lotus]

that show and tell lasted 9 minutes. i was 9 minutes late. 😦

this is true, only got half of it working actually. was just some noods.

[teal river]

@proven crow I got mildly distracted and haven't seen your device before, what is it for?

[proven crow]

Battery-powered haptic fidget spinner!

[slow spire]

Interesting! Why 8? For really strong haptics? Or maybe direction?

[teal river]

Ohhh, interesting

[proven crow]

I want the flow of the "spin" to be circular, and 8 ended up being cost effective and still getting the effect in. I sort of guessed with that number but I think it was the right choice!

So the motors turn on and off in sequence, making a spin effect

[cinder wind]

"eventually if you get to bright magenta, it crashes, and that means you've won" -- @robust horizon ahahah!

[slow spire]

Very cool. In my experience it's hard to localize the sensation of a haptic motor, since the whole substrate vibrates. But I haven't put several in a project, yet, so I'm excited to see your progress! Might be interesting to use an accelerometer to measure effect and direction.

[sand lotus]

@proven crow nice pcb design. you're doing great!

[teal river]

Some fancy devices with haptic feedback have vibration dampening between areas to help with the localized sensation

[slow spire]

Cut slots / fins could help

[sand lotus]

makes me extremely sad they're discontinuing the ano encoder wheel. 😦 it really was a great encoder though i've never gotten to use it yet.

i've seen other little wheels like it but not one with a center button. not sure if that would be integral to your design.

[proven crow]

Are they really discontinuing it?

That's such a bummer

[sand lotus]

yes, what's in stock.. or should i say out of stock is it.

if you visit the encoder page on digikey there's an EOL sheet on it

i think the company making them went out of business or go bought out or something

i only have 1, and apparently that's all i'll ever get now

[teal river]

What?! Noooo! I never got one!

[slow spire]

@proven crow @sand lotus Maybe replace encoder with a slippery disk and PCB capacitive touch?

[sand lotus]

but i changed my pcb design to use a joystick instead. if you really need another you can have mine.

[teal river]

WAIT ADAFRUIT STILL HAS THEM

BUY BUY BUY

[sand lotus]

yeah EOL

[haughty quiver]

hahah

[teal river]

Ask an Enjepeer, lol

[proven crow]

I have 3 of those encoders actually from the first batch of the E-Fidget. PCB capacitive touch is actually a great idea @slow spire , but I want it to be in an enclosure so maybe not

[slow spire]

@proven crow Cap touch can be tuned to work through plastic/glass/wood/etc

[teal river]

I have a fresh cup of coffee, ready for the show!

[split gazelle]

I use time.monotonic() in almost every project. Super useful

[teal river]

I need to start using it

[cinder wind]

In my Halloween/Thanksgiving/Christmas lights, I have noticed the loss of precision in time-monotonic() for long-running stuff. I need to switch it over to supervisor.ticks_ms()

[proven crow]

👏

[cinder wind]

(long running meaning on the orders of weeks)

[nova totem]

asyncio all the way (with sleep for delays) but I still have uses for time.monotonic()

[robust horizon]

adafruit_ticks is slightly more subtle to use but avoids the problems todbot mentions.

[teal river]

Question: Can you run into timing issues with time.monotonic() if several things are using it at different intervals?

[robust horizon]

or you can just have your program reset the microcontroller daily

[sand lotus]

yeah time monotonic does kinda get stretched sometimes if it's thinking. my guess is this is what's referred to as clock stretch?

[teal river]

I disappeared around a year ago, before AdaBox disappeared

no, that shouldn't pose a problem

"clock stretch" is normally a term for I2C where the I2C peripheral slows down the bus so it can do its thing. The problem with time.monotonic() is that it's stored as a fixed-size floating point number, and as the uptime gets longer, that floating point must store more "seconds" and fewer "milliseconds". If you only care about second-resolution, it's not a problem

You last purchased this item on March 30, 2022.

[slow spire]

@haughty quiver (when we last bought the RP2040 feather)

Ooooh that looks kinda powerful

Wow -- Product ID #73!

[sand lotus]

looks like a continuum transfunctioner

[tulip canyon]

who blocks the blockers?

[teal river]

Is it totally random signals, or something consistent?

[slow spire]

Ooooh it's in IR jamming mode

"You must watch this pirate broadcast."

[sand lotus]

amazing it can do all that with 1 dip chip

[slow spire]

@haughty quiver https://www.adafruit.com/product/73

IR Blast From The Past

[robust horizon]

I don't see that the code is available anymore (the free link doesn't work) so I don't know if it's "random" or not.

[sand lotus]

maybe the tv-b-gone sent some random signals that repositioned the screen 😛

[cinder wind]

ooo camera framerate does not like the OLED

[split gazelle]

It’s a bop

[teal river]

Good bop

[sand lotus]

😍

[slow spire]

@haughty quiver (to help with OLED videography, maybe add a neutral density filter to camera or otherwise lengthen shutter speed for each frame to about 1/30 sec or longer?)

[cinder wind]

oh that drum key layout looks so cool JP!

[slow spire]

That breadboard's more of a focaccia

[sand lotus]

i encountered the same exact jumping issue on the tr-cowbell 😉

@haughty quiver the PIO feature of rp2040 can also be used to drive more "pwm-like" signals, I did a guide page about it that focused on servos ... https://learn.adafruit.com/intro-to-rp2040-pio-with-circuitpython/advanced-control-servos-with-pio-and-background-writes

[split gazelle]

Oh nice, I thought it was still gone forever

[sand lotus]

i was going to go with this one https://www.digikey.com/en/products/detail/nxp-usa-inc/PCA9685PW-112/2034324

i didn't fix it, neradoc did and he put asyncio in it. completely over my head or i'd offer help.

[teal river]

Question: Favorite wire strippers?

[sand lotus]

the code for tr-cowbell v1.2 has that code in my github if you want to look into it.

[robust horizon]

@teal river Harbor Freight has a similar looking product, but the one in the adafruit store has better construction, a bit heavier, and just works a little better with the wire gages I usually use.

[teal river]

Heavier is better. I'll definitely use them forever

I'm just tired of my Radio Shack pair that needs to be set to each wire size XD

[split gazelle]

Favorite eurorack module?

[robust horizon]

you should keep that radio shack stuff, it's a collectible now

[teal river]

Oh yeah, not getting rid of it! Just not gonna use it XD

Question: What are the step switches exactly?

You should do search for "question" since many of us put that on our questions, lol

[tulip canyon]

Not judging but just wanted to know what you enjoy about Rhino 3d

Self disclosure : I'm a Blender Superfan

[slow spire]

Basically, fairly simple momentary switches that have been popular for "stepping" in synth sequencers

[teal river]

Ahh... I guess my question becomes what "stepping" is for synth XD

[slow spire]

I think they can step through a rhythm loop, one step/beat at a time?

[teal river]

Ohhh...

[tulip canyon]

Thanks JP, I appreciate the answer!

[teal river]

Well loved mouse XD I meant like buttons and switches and stuff, but this is also interesting, lol

[slow spire]

Rhino is about $1000, I think. Fusion 360 is free for hobbyist use; I have a pro licence which is about $500/year. Fusion 360 is on sale right now, for 30% off during "Cyber Week".

I still remember the debut of Lars

[split gazelle]

Did not realize Lars had a foot port 😆

[teal river]

I fear no man, but that thing... it scares me....,

[split gazelle]

Same, it was so hilarious

[cinder wind]

Lars is hilariously creepy

[teal river]

AHHHHHH

[nova totem]

the fact he has lasted so long in lore

[teal river]

https://tenor.com/view/anime-anime-girl-running-anime-running-running-love-live-gif-22710773

[cinder wind]

But what he won't say is that Lars is JP's larval stage

[sand lotus]

the fuggler lol.

[slow spire]

I'm hoping Lars is working behind the scenes to fix the chip shortage, and everything else wrong with 2022.

[robust horizon]

no, he eats the chips to sustain himself

@haughty quiver the image was from "stable diffusion" one of those text-to-image programs. Here's an image that was supposed to be a "blushing plush radish" but I dunno what it is for real

is cute tho

[split gazelle]

Pam’s is the best 🏋️‍♀️

[slow spire]

I think it's offering us a radish flavor gumdrop.

When S-Video was the good input lol

[gray obsidian]

Well if it's B&W you don't need the C from Y/C 😄

[teal river]

[he got my name right, yay!]

[gray obsidian]

S-video is separate Y (luminance) and C (chroma)

[tulip canyon]

CRT love is all about the degauss

[slow spire]

Beat-boxing JP is all you need, really; no step switches needed.

Question: Favorite wire cutters?

[viral sail]

Thanks @haughty quiver . Good night everyone. 🌓

[slow spire]

Definitely these:
https://www.adafruit.com/product/152

[robust horizon]

12 monkeys had some nice monitors .. not sure if that might be what todbot's still is from as well?

[teal river]

I think color CRTs have more electronics and use multiple alignment coils?

[gray obsidian]

Same as composite, just missing the chroma info inside

[teal river]

I have CHP side cutters!

I did mean strippers XD

[slow spire]

RIP Fry's!

[teal river]

I am confused

RIP in pieces Fry's

[teal river]

Ohhh, those are the same as what I have, but I got mine at Radio Shack!

[slow spire]

Oh gee those are posh cutters

[gray obsidian]

If you have a composite output you should be able to send it directly, if you get S-video, you should be able to send Y directly, and it will look sharper as it doesn't draw the color info as hashes over

[teal river]

Flush cutters are best cutters

[sand lotus]

i had some of the spongy handles too, yeah might have been radio shack.

[split gazelle]

Great stream! Thanks @haughty quiver

[teal river]

I'm ordering one of those as well as the other one you held up [or at least a similar one]

[slow spire]

If I had Erem's, I would have to hide them, since my others get stolen and misused

[gray obsidian]

@haughty quiver IIRC you can get either composite or the Y from S-video as input on this PVM. Y will miss chroma so it will look sharper, while composite will have some patterns instead of colors.

Ah eh 🙂

Ok, n8 everyone, 3am here

[clever summit]

👋 🇸🇪

[sand lotus]

but can it scale fonts down? first i've heard about the new font scaling, i'd love to know more about it.

[sharp ivy]

Do you have to load it each time manually? or does it stay on the device and run on each boot?

[inner spade]

Fractional bitmap scaling will be very very useful.

[sand lotus]

drag & drop code iterations FTW. sooo much faster than waiting for a compiler to run.

circuit python is by far the most fun language i've learned yet

[sharp ivy]

How does CircuitPython differ from MicroPython?

[upper sandal]

that's a short question with a long answer

[sand lotus]

best thing i can think of is it's more specialized for microcontrollers in tiny tiny packages.

[smoky island]

https://docs.circuitpython.org/en/latest/README.html#differences-from-micropython

[upper sandal]

the core language is the same, the APIs and style of the APIs differ, the workflow is generally different, though you can use Thonny with CP, there's a few "core" differences too like the VM resetting after code.py runs

[sharp ivy]

Was floored to learn that I didn't need a full Pi to learn/work on a Pico W.

[sand lotus]

scaling fonts with pixelation down is a given, just having that capability now is awesome.

[upper sandal]

it's separate projects with different goals and dev cycles etc.

are you talking about the test I did 20 minutes ago ?

aw the left picture is a little blurry

[sand lotus]

yes

is this going to get rolled into displayio for bitmap fonts to make that easier now?

[upper sandal]

the small one is 0.65 in this one

illegible

[sand lotus]

omg tiny, that's awesome

doesn't matter if it's illegible there's still uses for that

here we go with the old new and the new new lingo 😛

so many new devs helping out lately. bill88t doing some great stuff too. jeplers been on fire. so has scott. like everyone is on a rampage for squashing bugs lately.

[upper sandal]

yeah I made a modification in bitmap label

[inner spade]

We need a fontio module…

[brazen grove]

I thought we had one already

[sand lotus]

oh Jepler might have narrowed down the culprit causing the hard faults on the S3's

[upper sandal]

ugh it's so hard to take a picture of a tiny TFT with a phone 😛

[sand lotus]

umm we have a screenshot library

[upper sandal]

I don't know if I will PR that, it needs more work to fix the position and stuff

[brazen grove]

the idea with fontio is that you load a font that has the size you need already, I think

[sand lotus]

ah true, i have a tft featherwing with built in sd card

[upper sandal]

and of course this has 0 antialiasing

[sand lotus]

yeah dan said someday sd cards might show up as a flash drive. i'd be more inclined to use sd cards when that happens for sure.

it's still super legible though, great job Neradoc

[brazen grove]

if we only could use MTP

[sand lotus]

taking screenshots of my weather station i had to unplug sd, transfer, replug. etc.. worth it though, the bitmap_saver library takes pixel perfect screenshots.

[brazen grove]

if we had mtp, we could use a better filesystem, designed for flash

and no filesystem corruption

[sand lotus]

offloading all QSPI would free up stuff too, would be nice. might eventually see it if UF2's become so big it becomes a necessity.

low priority right now since everything works, if it ain't broke...

[sharp ivy]

I heard a sound… I think it's the sound of a plane flying over my head. 😬

[sand lotus]

in def expand ranges did pycharm add a ... or is that not actual code?

ah collpase, missed that. better safe than sorry.

i would never get that syntax right because a (2,) makes no sense to me

[upper sandal]

yeah parenthesis are just parenthesis, you need a , to make a tuple

[sand lotus]

is there a way to clean that up where if it 1 number the comma is unecessary, it's confusing

[inner spade]

It takes two to tuple 😉

[brazen grove]

you don't actually need the parens for a tuple, it's the comma that makes it

[upper sandal]

note that:

a = 1, 2

is a tuple too

[brazen grove]

you can do x = 1, 2, 3

[sand lotus]

yeah that makes more sense

[brazen grove]

and you can always have a trailing comma

so x = 1, 2, 3, is correct, then x = 1, makes sense

[upper sandal]

well in a function call, the comma has a different meaning, so you need the ()

[brazen grove]

sure, the () makes it the function call

you can have f()

[sand lotus]

yeah it's different if you're trying to make a function out of it

my perspective is just for example/script coding

[upper sandal]

I mean f(1, 2) versus f( (1, 2) )

[brazen grove]

yeah, this is an inconsistency in python syntax

[sand lotus]

the tuple function expects that syntax though

[upper sandal]

yeah basically always put the () around your tuple, the no-parens syntax is like a quirk

the kind of things that kind of makes sense, but should probably be avoided

[brazen grove]

I had enough head scratching over errors where I copy-pasted something from inside a list, and didn't remove the comma, and then wondered why it is a tuple

[upper sandal]

maybe something like a, b = b, a is ok (I mean without the parens on right hand side)

[brazen grove]

which reminds me of another python quirk, a = b = c = 0

[sand lotus]

coming from php i still have a hard time not calling them arrays 😛 the tuple, dict, list naming is a tough switch

like what do you call a multi-dimensional array? a multi-dimensional tuple list?

[brazen grove]

a tuple of tuples

or a list of lists, or a tuple of lists of dicts

[sand lotus]

yeah that's not confusing at all

[brazen grove]

it's precise

and when you don't care, you call them collections

[sand lotus]

probably, still a head scratcher

[brazen grove]

or iterables

[sand lotus]

"i wonder why that doesn't work" is usually followed by a series of prints

[brazen grove]

a closure is a the local namespace of a function that is kept in memory after the function returns, because it returned something that refers to something that was in that scope

you usually find it when you define a function inside another function, and return it

[tall canyon]

the devs at work go "I will set a breakpoint in the debugger and step through it". I go: "I'll add an echo in here" </php>

[brazen grove]

I think it assumes a list of tuples when it finds a list

the original condition had two checks in there

it checked the type of the ranges, and then it checked the type of the first element

you have or in your if instead of and

that's the problem

the if on line 111 should have and

that was the original condition

that condition after or doesn't make sense otherwise

try a non-list

it will error on that condition after or

[upper sandal]

I put the scale thing in that branch (along with a test file in examples):
https://github.com/Neradoc/Adafruit_CircuitPython_Display_Text/tree/test-for-float-scale-label

[inner spade]

Use a different color for each test?

[sand lotus]

wow, lots of examples in there too. Very nice Neradoc. I will definitely look into using that for sure.

[brazen grove]

I feel like the correct way to write this code is to try the nested iteration first, catch the type error, try the other one, etc. without explicitly assuming it's any particular type

this way you could use it with, say, bytearrays or any other iterables that you didn't anticipate

[clever summit]

Isn't exception handling slow in CP?

[brazen grove]

compared to what?

[clever summit]

To an if statement?

In other languages it does alot of processing, like collecting the stack trace and similar things.

[brazen grove]

duck typing

the "big" python now has abstract base classes that let you check whether it's iterable without explicitly checking if it's a list, but I don't think that exists in CP

[brazen grove]

it's not the speed of the if statement you have to worry about here, it's the speed of isinstance

[clever summit]

Sure, but you got what I was asking.

[inner spade]

[:]

[upper sandal]

just [:] it's a Megaman character

[brazen grove]

I really don't.

yes, the "empty" slice is useful for making a copy

or for assigning to the whole list without replacing it

consider this:

a = [1, 2, 3]
b = a
a[:] = [4, 5, 6]
print(b)

it will print [4, 5, 6], whereas if you just did a = [4, 5, 6] it would print [1, 2, 3]

[upper sandal]

man I didn't think it would be so hard to find a picture of a megaman character, though to be fair I didn't know its name

[brazen grove]

eye-burger?

[upper sandal]

see, sideways: [:]

"Telly" as it turns out

well Megaman was on Nintendo

[brazen grove]

yeah, you can assign to slices, it's convenient for inserting additional items in the middle of the list too, because it doesn't have to be the full slice, it will just replace that part of the list with the new values

like a[1:2] = [] would give you [1, 3] from [1, 2, 3]

[upper sandal]

the animation library uses slices to assign to pixels

(some animations do)

(which caused incompatibilities with seesaw.neopixel when it didn't support slices)

[proper prawn]

Tnx Tim. See you tmw. Good night everyone!

[inner spade]

Thanks for the stream!

[brazen grove]

[clever summit]

Btw @smoky island I sent you a DM.

[smoky island]

I am getting started for the morning. Working on updating Blinka DisplayIO API to match the new core API. Follow along on YT: https://www.youtube.com/watch?v=4l8YxZJkBJY or Twitch: https://www.twitch.tv/foamyguy_twitch

[brazen grove]

bonjour

[brazen chasm]

hello Tim. Not having the world cup on in the background??? GO US!

[brazen grove]

flip is basically a refresh when using a double buffer

it swaps the two buffers (flips them)

you probably don't want to go below 2, there were some big changes

but the example you tried works?

if the examples work, then your pygame installation must be working

are you sure the initialization is run before the code that is failing?

flip and update do pretty much the same thing in practice

[sand lotus]

good morning ☕

[brazen chasm]

USA scores one of the strangest goal in history! game's alive. 15 minutes remaining, hope is still alive. (note: sweden is not in it). it seems to be on Fox.

keep ya updated 🙂

[sand lotus]

they're playing the netherlands (who won group A)

[brazen chasm]

good luck

bad news. holland is a lot better team

[brazen grove]

no, flip does update

[brazen chasm]

but its not over

[shell mason]

the box defence USA doom so far

[sand lotus]

netherlands are up 3-1 there's no way US is coming back now

[brazen grove]

must be a Monday

[sand lotus]

they're not playing bad, but not great enough to advance to a quarterfinal. netherlands by far the better team.

i think England vs Senegal is going to be a great match.

i'd kinda hope blinka displayio would have some automated process to keep up with the core. you guys have to manually keep it updated to match?

[brazen grove]

pygame screen is what is returned from setmode

[shell mason]

defence mistakes on this game on US

[brazen grove]

this is precisely why I set out to make my own python game console, making games with desktop python is just too hard

in terms of getting everything working

were there any additional parameters in the set_mode in the examples that worked?

[brazen chasm]

oh well. now we can forget about soccer for another 4 years

[brazen grove]

you have to install that python, but you can have several versions installed

[sand lotus]

possibly one nice thing about having windows and WSL Ubuntu. 2 separate OS's with 2 separate gits and pythons... it's confusing really quick though.

https://tenor.com/view/star-wars-luke-skywalker-bad-feeling-nervous-anxious-gif-4059086

i thought the entire purpose of venvs is being able to customize them to suit whatever needs. i mean there's gotta be a way for developers to switch versions virtually.

[brazen grove]

remember the times when Python was a mature language?

[sand lotus]

still is... for mature audiences only because there can be a lot of mature language used.

[inner spade]

Good morning! Just getting up after a marathon session restoring a vintage guitar pedal (hybrid analog/charge coupled digital). Time to get back to the simple world of coding! 😏

[brazen grove]

statically compiled binary

there are people working on that

but each new release makes them take two steps back

[shell mason]

and one step forward?

[sand lotus]

just the way it goes sometimes you run into unexpected walls that require a really time consuming workaround

[inner spade]

https://github.com/CedarGroveStudios/PCB_Ibanez_FL-9_Flanger/blob/main/docs/new_service_guide/Ibanez_FL9_Service_Guide.pdf

[brazen grove]

but autorefresh is exactly where it's calling flip

[sand lotus]

i do love a good flange

[noble grove]

Hey Tim, does your wife watch Fran Blanche on YT? She has at least a couple episodes about when she used to make FranTone pedals.

[sand lotus]

my favorite flange in a song is from Live's Lightning Crashes

She hasn't done a video about actual guitar pedals for a while.

I've been subscribed to her for years

[clever summit]

🇸🇪 👋

[brazen chasm]

love the pedal hack @inner spade . did you actually make a new PCB? new components/features as well?

[inner spade]

Didn’t make the PCB (yet). Had to reverse engineer it because the available service guide was almost illegible. In the process, I developed a process to duplicate the original hand drawn traces. The biggest issue to making a new PCB is that the bucket brigade delay chip set is no longer available.

[clever summit]

I have been busy getting a well known CircuitPython guy on a podcast. 🙂

[sand lotus]

they really need to relax dynobot, it's too aggressive. it's worst when you're trying to help someone and posting links to circuit python stuff.

my personally coding philosophy is , if it works it works.

[clever summit]

Mine is that I should be able to read my own code in 10 years and still understand how it works.

https://www.youtube.com/watch?v=NSjwghW8fD4

[sand lotus]

oh really. didn't know there was ANY trash.

[clever summit]

There - The JP podcast!

[sand lotus]

ok then, that makes me feel better about dynobots aggressive setting then. good to know. 👍

[clever summit]

People have been begging JetBrains to release a GIT client, as the GIT support in their IDE's are so good.

GUI client*

[sand lotus]

i'm already subscribed to that podcast, yeah i listened to the JP one.

[inner spade]

BTW, there was a little CircuitPython coding needed for the calibration phase of the pedal restoration. Used an AD9833 programmable waveform generator for test tones and sweeps.

[sand lotus]

cgrover you're really modest but the stuff you can do is really advanced. really enjoy hearing about the stuff you're up to.

i appreciate when you share stuff you're up to

[inner spade]

Thanks. There’s always something new to learn.

[clever summit]

Oh, that comment reminds I need to publish more of my 3D prints on printables.com.

[brazen grove]

I wonder if initializing pygame in the update thread instead of the main thread would make it work

but then the regular refresh call would need to tell the thread to do a refresh

[sand lotus]

sounds like threading support will be a necessity in the future?

or i should say, checking for threading at least.

thank you for streaming. have a good weekend.

[clever summit]

Bye peeps!

[inner spade]

Thanks for the stream @smoky island !

[noble grove]

I watch her for archaic technology, just know she talks about pedals from time to time.

[open surge]

good morning

I have a Pico Wiznet with ethernet

[sand lotus]

are you communicating from it?

hopefully you realize this is the broadcast chat topic?

[open surge]

foamyguy is streaming, I'm not talking to myself. 🙂

[sand lotus]

10am on a monday. and again i wasn't notified

actually i was, i just didn't have my tablet open. it doesn't notify me on my phone 😦

didn't even know pico's had ethernet, looked up the wiznet. that's cool. like an ethernet featherwing for a pico.

[teal river]

I too had no notification...

[modern night]

morning all! Hope everyone's well

[sand lotus]

well you could do that with the pico w or qt py too

true, if you wanted to have better uptime ethernet is the only way to go. maybe a bot? you can't do something as extensive as a pihole on a pico, right? that would be kinda awesome if someone got pihole to run on a pico.

however you could probably ddos a pico without much effort lol

i have an example using struct time https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Circuit Python Tips %26 Tricks right at the top

[modern night]

the datetime library?

I think so? the version of datetime in circuit python is very minimal and I don't know if that's due to size constraints

[sand lotus]

if one exists i couldn't find one. i had to come up with that example on my own. it was a **** to do.

would love an implementation in the core for time

[modern night]

I would love to be able to set time from seconds since epoch instead of time_struct

[sand lotus]

because CP is getting online more with wifi stuff epoch is the only way to go, it's the most common standard

[modern night]

yeah with the datetime object--I use it to set the rtc

[sand lotus]

1970 plz

unix epoch matters

[modern night]

I *think* true epoch should always be 1970 to avoid subtle errors, but that might be impossible with the size of an int

[sand lotus]

that's why they did 2000 i think

host to online?

that really messed me up the first time i worked with it. mentioned epoch but kept spitting out 2000. doing anything with time is hard enough, that just made things worse in a way.

well if you're used to working with unix epoch it'll throw you off. for beginners that don't even know it exists it'll be more useful. something to be said about engrained knowledge tripping you up.

[sand lotus]

It’s supported on the Ethernet featherwing. Wasn’t supported on esp32-v2 until recently. Maybe just not supported on the pico yet? Jepler would probably know.

V2 is just adafruits rev2 of the classic esp32. Only ran micropython for like 5 years until WiFi workflow unlocked a door for it to run cp.

I think the huzzah is the v2? I could be wrong.

There are more versions of esp’s than Linux distro now, hard to keep track of.

Gotta take off. have a good day. ☀️

[grand bluff]

Hi Tim and the chat. I'm a bit late.

I wish it was Friday.

Hello

[inner spade]

👋

[drowsy inlet]

Hello * 8!

[open surge]

good afternoon!

[haughty quiver]

hello!

[sand lotus]

https://tenor.com/view/clone-twin-matrix-gif-12594344

When you need to add a bunch of stuff with the same I2C address.

[tacit garnet]

Ppow!

[echo canopy]

Hey 👋🏻

[teal river]

Hiiii

[midnight plinth]

Just what I wanted!

[drowsy inlet]

So is this only necessary when connecting multiple devices with a fixed address, as opposed to a general expander?

[haughty quiver]

correct

[charred lion]

Just bought 10 for use in my mech keyboard

[haughty quiver]

nice!

[cinder wind]

In honor of JP's latest CircuitPython Parsec I had some toggle switches made for him

[haughty quiver]

LOL

thank you @cinder wind

[sand lotus]

7-segment displays conflict with the multiplexer addresses. So there's a caveat to mention.

[charred lion]

Just need 4 more of those 5×6 ortho boards

[inner spade]

A hardware solution. Very nice.

[sand lotus]

I've designed a graphic that shows how it actually works.

even with a conflicting address

[drowsy inlet]

❓ Could this be used as an expander? How are they different if not?
Just trying to understand the difference.

[shell mason]

https://tenor.com/view/eyebrow-hmm-gif-25634245

[charred lion]

Big keyboard 8 rows × 30 columns

[teal river]

Why are most boards limited to one or a few I2C addresses, anyway?

[shell mason]

https://tenor.com/view/mux_and_demux-multiplexer-demultiplexer-circuit-digital-circuit-gif-25734923

[sand lotus]

i2c addresses are built into the actual chip kyoshii, it's part of IC design

[inner spade]

Usually caused by a limited number of available pins on the chip.

[charred lion]

Please state whether this is the PCA9548 or the PCA9548A

[sand lotus]

so to use more than the addresses support by the IC then a multiplexer like this PCA9548 is used.

[shell mason]

i3c

[charred lion]

Can these ve chained together?

[sand lotus]

keep in mind the graphic i posted is per i2c bus and most adafruit microcontrollers support 2 i2c busses so double it 😉

[drowsy inlet]

the page says yes, meaning you could get up to 64 devices:
"In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part."

[sand lotus]

if you use non-conflicting sensors like something that uses 0x20 addresses you can put up to 8 per channel which comes out to something ridiculous like 2048 devices.

such as temp sensors

[charred lion]

2040 devices....... Drool.....

[teal river]

So just a hardware limit of I2C chips?

[inner spade]

Usually. It’s a trade-off of course.

[sand lotus]

most adafruit examples only show 1 sensor per port... but you can chain stemma sensors on each port. so imagine like 8 vemls chained on 1 the veml JP is showing.

[charred lion]

May have to inject additional power if too many devices

[sand lotus]

each port is basically a hub

up to 8 PCA per bus, only 4 if you're using it with something that has a conflicting 0x70 address

i have experience with it!!!

[vivid ore]

8 address options

[charred lion]

So HUB plugged into HUB plugged into HUB and so on and so on

[drowsy inlet]

Other than the fixed address support, how does this differ from an expander?

[charred lion]

Just like chained USB HUBs

[echo canopy]

Do you know the response time to allow between asking a new PCA channel ? I’d imagine a for I loop with all 8 could be to quick without delay ‘

[cinder wind]

The product photos and datasheet show PCA9548A

[sand lotus]

i have tried it... hence the graphic i made

[vivid ore]

Hubs in hubs do work, but might not play well with existing circuitpython libraries

[sand lotus]

yes it's actually the PCA if you look at the title of the product

[teal river]

Someone needs to get many of these and try hubs on hubs on hubs on hubs

[sand lotus]

it only says TCA compatible because it uses the TCA library

[charred lion]

Spamming?

[clear matrix]

Sorry, too many of one character sparks the bot's interest.

You were very excited in that message 🙂

[charred lion]

Ok

[teal river]

I got dinged for trying to type out a quintillion (15 zeros) earlier, lol

[clear matrix]

Unfortunately the bot isn't smart enough to differentiate valid posts from spammers.

[proven crow]

Aww, I just tuned in! Hi and bye all!

[dusk socket]

thanks JP good show

[smoky island]

Thanks JP!

[sand lotus]

multiplexers are invaluable for big 7 segment, 14 segment projects

[haughty quiver]

thanks very kindly!

[teal river]

Good show!

[charred lion]

I have like eight 7 port USB 3.0 HUBs plugged in to the back of my PC. all with independent DC power

[sand lotus]

Here's an example project I'm still working on: https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Boards/espressif/Adafruit Feather ESP32-S2/7-segment Multiplexed Social Media Tracker

[dry marten]

Thanks for the show

[teal river]

Do all of those have more USB hubs plugged into them?

[haughty quiver]

you're welcome!

[inner spade]

Thanks!

[charred lion]

Now I just have to get my parts past Canada Customs without them trying to use the wrong customs code.

[sand lotus]

great price and I needed a few more, this works out well. Thank you JP!

[teal river]

They’re trying to steal your parts to build robots

[haughty quiver]

@sand lotus that's really great info, thanks for the link

[sand lotus]

1 hub kyoshi because i'm only using 10 but plan to expand it in the future.

[charred lion]

The Canadian military are not that smart. I can say that because I used to be in the Canadian Military reserves

[sand lotus]

yes you will need a hub if with these, i think that should be mentioned too beause you do not want to plug the multiplexers into your 2 available I2C busses... they kind of completely take over the buss and don't let anything else really work with it properly.

you want all multiplexers running from stemma hubs, that all feed back into 1 I2C bus on the microcontroller.

[teal river]

I have 3 USB hubs on my main workstation… partly because one has always on ports for things that I never disconnect, and another has switched ports which are great for power cycling things or turning them off when simply not in use, instead of disconnecting

[vivid ore]

They what now?

[teal river]

Oof… well, they’re trying at least

[charred lion]

I used a switched HUB for emergency boot thumbdrive

I'm 63yo

Ack 62yo

[teal river]

You de-aged a year!

[charred lion]

UEFI is set to always boot from USB if possible then GRUB takes over for O/S selection

I don't turn 63 until April

[teal river]

My computer likes trying to boot from CP devices, lol

[charred lion]

CP devices?

[teal river]

CircuitPython

[charred lion]

I have a USB-C case that turns a NVMe SSD unto a USB Thumbdrive

[teal river]

Best portable storage

I have one that doubles as a USB hub!

[charred lion]

Having a switched hub that breaks the USB-C data ports would solve that issue

Extreme Cold Warning just issued. So air temp will go down below -30°C anything above -20°C is T-Shirt weather

What I would love to do is put a RPi inside of a mech keyboard and have the RPi handle the HID before sending it on to the PC

Would be a snap then to put a LCD on it to handle UNICODE or macros without needing an app on the PC

[teal river]

You might be able to squeeze that function into a Pico

[charred lion]

Would work on PC, MAC, Linux, FreeBSD UNIX, etc. I was trained at Denver AT&T Bell Labs in UNIX back in the mid 80s

I figure build the first one using a RPi 4 8GB or wait for the RPi 5 and then use a pico or maybe even a 2040 based board.

My 1st ED Logitec G15 died last year and I bought a Logitech MX845CH with Cherry Blue keys.

I'm old school, all keyboards were basically MX Blue keys back in the 70s & 80s on serial terminals.

And only my cat can complain about the noise of my MX Blues

TTFN...

[teal river]

An 8GB Pi would be waaaaay overkill for a keyboard, lol

[charred lion]

True but then I can swap it out for a smaller and dumber board easily enough. That is what the RPi's are for. Prototype using big then go to cheapest that will work. First PC I used was a S100 IMSAI 8080

[teal river]

Nice

I usually prototype as cheaply as possible

[charred lion]

I think I said that I'm old. I'm also a licensed Amateur Radio Operator.

When I got my licence, we still needed to understand equipment that used tubes.

Now the only plants that make Tubes are in Russia.

Maybe because Tubes are not effected by EMPs

[teal river]

Or they just really like tubes

[charred lion]

They didn't know about EMPs from nukes until they started making transistor based sensors and wondered why they kept crapping out at the worst time.

The tekephone systems in Switzerland were tube based at least until the 2000s

[sand lotus]

alright guys time to take it to general chat, way off topic anyway

[teal river]

Oop

[charred lion]

Sorry... I get started and can't stop sometimes

My fault

[sand lotus]

don't we all, it happens, sometimes a gentle reminder is needed.

[charred lion]

Please jeep reminding me because I KNOW that I will do it again until I die.

TTFN... must go and either add more to my new ADAFRUIT order ir make a 2nd one

Adding more just saves on shipping

I'm gone
