You should try the Merlin app. Great for bird ID and connected to The Cornell Lab.

I'm currently working on compiling a bunch of python modules so that it works on riscv, so it should be cheaper hardware than Pi4.
But to install it on a Pi is a 10-minute tops project that will give out amazing data and recordings.
I use it to teach myself what birds are singing in the forest that I live. I found for example that 3 types of tucans come here and I haven't seen any in the previous years.
I also have a circuitpython library that listens to what birds show up, and puts an image (from iNaturalist) so that you can see the birds if you are indoor. (and sometimes I run with the camera to watch them)

Question, related to 👁️ onNPI: Could you include an accurate enough i2c/i3c digitally controlled potentiometer as the shunt resistor in a breakout for the new STM load monitoring chip, or is that prohibitively expensive and would it make more sense at that point to try to use an attiny or something as an i3c/i2c overlord aka seesaw and some cheaper non-i2c digital potentiometer.

For arduino it uses the 700mhz core. But yeah, that is plenty of ram.
sand lotus
It would require someone like Scott. Way beyond my skill level to port a new chip type like that.
gusty wedge
I already have some pre-production "S" boards waiting to come all the way to Costa Rica, as I plan to try this. But no idea on the availability of them.
(you can buy the bare chips, so I am tempted on getting a handful and make a qt-duoS )
sand lotus
Might even require being implemented in Micropython first? That would be an easier route for porting if it was already supported by MP.

I feel an inception moment coming with this usb keyboard stuff. Some usb host feather with usb cable to master programmer (qtpy), acting as HID to a circuitpython device, accepting new files etc via the repl. Maybe safer than just overwriting the CPY flash (the usb qtpy could interrogate the CPY device / code first)
Oh F1 to continue surely made a few people launch their keyboard across the room
sand lotus
It's called on screen keyboard. It has an FN key. 😉
timid plover
back to previous code? ( what should the back button do ? )
gusty wedge
Yeah, an HID remapper in circuitpython would be so cool.
sand lotus
pretty sure that exists as Ducky?
gusty wedge
Yes, I did made a ducky in cpy ages ago. But to read a keyboard on one side and spit it out on the other with keys remapping I think would benefit from today's dive work.
Do we? I'll build one this weekend, then.
yeah the website uses webHID to send the new codes to the microcontroller, so you configure it via web.
sand lotus
Macropad?
I think JP did some stuff with TouchOSC that does some remapping things too.
I have a really old keyboard with media keys that has a back button. That's for web browsing mostly though.
By default most mice with a thumb button is the back button in web browsers.
timid plover
do you want sublime to keep a stack of functions visited ?
gusty wedge
Side comment. I also made an ascii7 keyboard as a joke/gift for a friend. It uses two of the huge mechanical keys in the adafruit store, 1 and 0.

timid plover
is there a list of the endpoints that are involved - ( assuming they are all keyboard endpoints )
sand lotus
I'm not seeing 60fps in youtube settings for your video so likely streaming at 25-30 fps. Youtube's recommended bitrate for 1080p @30fps is 10Mbps.
4000kbps is 4mbps. 😦
hmm hear me out. You're streaming 1080p with 4 Mbps which is half of what YouTube recommends (8 Mbps). So actually raising your bitrate might be the thing to do if you intend to stream in 1080p.
Well it doesn't matter if it's Youtube, Twitch, or StreamYard. 1080p streaming does require a higher bitrate regardless of the streaming platform.
If you used 4Mbps for 720p that would probably work out better but you want to do 1080p which requires a slightly higher bitrate.
unreal bay
Maybe you didn't lick the board enough to reach a safer humidity...
It might be nice to have a flag in settings.toml for Not enabling usb keyboard on boot, so it can be purely used as a game input etc
timid plover
so you are now using the 'print to LED' debug technique - ( maybe a future deep dive could look at what can and can't be called in the start up process )
sand lotus
the lower bitrates you might have seen are for AV1 or H265 codec. if you're using AV1 then sure. H264 requirements a bit higher.
unreal bay
I'd want to disable keyboard immediately as my default to wake a device is hit enter a few times and Ctrl-c, which if done by an unaware user might stop my code.py (ctrl-c in repl?)

unreal bay
listen on all ips not just one
brisk bone
You can't really point to module as type, and that is the case on CPython
rigid crag
port 5000 is common as a "developer mode" port value as it puts it out of the privileged range < 1024
yes, 0.0.0.0 is "listen on all networks"
brisk bone
There is a MDNS example
unreal bay
more future proof, can't remember specifics but had fun with that fixed address issue playing with https servers last year
rigid crag
.local feels like a modern network stack implementation
brisk bone
I will, it is still a draft but I agree it might be useful in docs or example
unreal bay
I got a lets encrypt subdomain setup for 192.168.4.1, so you can get past the browser warning in theory (except your still offline as thats the ESP access point gateway ip) That's where you want to have a non hardcoded ip
brisk bone
MDNS allows setting a custom domain for .local
rigid crag
yes, .local == MDNS
unreal bay
.local = mDNS, or apple bonjour service, (avahi on linux), similar to old netbios days of workgroup/hostname and service resolution. Think can use other suffixes if setup. The devices report services and the port
multicast messages across network advertising services (ip + port + service name)
brisk bone
.dev is now a TLD so sometimes it might overwrite real domains
unreal bay
google I think own .dev, occasionally screwed up a test of mine
rigid crag
so it will send a DNS shaped request out the multicast network address
clever summit

rigid crag

brisk bone
It not a alias, it handles specific path, so not a bug
unreal bay
to be fair, circuitpython was never said to be secure, the password on file browser is a nod to privacy, not security
rigid crag
he's learning the result of how "/home/" and "/home" resolves
unreal bay
brute forcing the password would be painful as the esp is slow, but technically viable. Just disable Web workflow by having no password
rigid crag
most path handlers treat "/home/" as a request for the index.html
brisk bone
No no, the way you did it, those are query params and not url params
In context of httpserver at least
rigid crag
that's a great improvement to the error handling @brisk bone - nice work
i've spent decades routing around this class of errors by having nginx in front of all apps ;)

Yep, coming... Adafruit IO app being built as we speak, very simple functionality for first version, then we pimp it with on-phone sensors etc. Saw Trevor on show+tell demo proof of concept recently.
rigid crag
not for a major version but for anyone assuming in their tests
I wonder if ntfy could be used for that
unreal bay
iOS though first.
android can do proper PWA things, so maybe easier than entering app store
rigid crag
android can do proper PWA things, so maybe easier than entering app store
that's why I mentioned ntfy - it has android, iOS and web clients that are available
unreal bay
you can just use the Adafruit IO Dashboard you design for smaller screens / on mobile. not app level of swish, but effective enough. Or use webhooks/api to interact with feeds
like add a santa hat to faces?
ooh nice, heard about the png feature recently
rigid crag
@unreal bay are you watching using youtube or twitch? Your responses are a good couple of seconds ahead of my youtube stream
not important, just curious
unreal bay
twitch. yeah funny, youtube used to be better. Had noticable few seconds on deep dive. Used to be less intrusive adverts on twitch too. Sometimes linkedin 😄
not sure the scale was exactlty the same either, but hard to tell
forgot about the black borders too, and yeah the 0.75, not as bad as I thought it was at all
ahhh nice
rigid crag
calculate scale at time of file load?
isn't that first isinstance is adjusting the parameter to be an int so that the following code then works
o(offset?)x
rigid crag
the joys of dynamic languages and true/false
this highlights the power of CircuitPython - being able to quickly iterate with debugging visible
wow
current_duration % 2 then increase by a percentage
yes
that version looks like it's reasonable
linear is more friendly to human reaction time
unreal bay
Do we have a filter that does good edge contrast, to maybe make an overlay that was the left or right edge of a previous image (beginning of panorama - stitch on pc)
rigid crag
your modifier may need to be a percentage of the resolution's pixel count
the amount you are moving the overlay being a pixel at a time, for larger screens maybe it's 10 or so
unreal bay
save as png?
jpg?
lol, yep, it should be so easy... makes me remember things like who owned formats back in the day 🤦♂️ drm for the anti-win
yeah segmented processing
looks like we may be talking reasonable possibility https://registry.platformio.org/libraries/bitbank2/JPEGENC

Someone asked about the Adafruit ICN6211 prototype from July that isn't listed in the store yet (for RGB666 displays). Something to keep on your radar that someone is interested in for using with the Pi.
I think phosphate is LifePo, commonly used for solar panel battery banks.
Built in thermistors are nice. Had to deal with needing a battery with thermistor in replacing headphone lipo. Pretty sure it's required for headphones because you're wearing a lipo on your head.
Amazon ring cameras have some kind of scheme where polarity doesn't matter. You can hardwire a 24V power supply and it will somehow accept either polarity and recharge the internal lipo. I just wired one up yesterday and was like "how'd they do that".

You would have to solder 4 noods in series to make them 12V... otherwise you'd burn them out with too much voltage.
sand lotus
Ohh the new longer ones are 12V. That's why. Makes perfect sense now.
haughty quiver
but Power BFF would allow for 5-20V so you'd just need to match things up
sand lotus
darn it, i should have added a few of the longer noods to cart too. there's always next week.

NeoRGB STEMMA doesn't go past 16V actually, so the 12V are probably best bet

@sand lotus I am using the MCP23017 as a keyboard matrix interface for a 61 key manual. There are going to be 3 of them for my organ.

Very nice. MCP23017 is an I2C multiplexer. Multiplexers won't even be needed with I3C. 😉
sterile forge
I just find it very easy to create a 8 by 8 matrix which leaves 3 extra spaces for some kind of switches.
sand lotus
With I3C you'll be able to create an infinite matrix. Think of it like a neopixel strip where every device has its own address and you can chain them to infinity. Problem currently is there aren't chip manufacturers like Espressif, Atmel, Raspberry Pi, STM, etc.. that are integrating I3C yet. When that change occurs the world of microcontrollers will look very different from today.
sterile forge
Actually the MCP23017 is a 16 bits, grouped as 2 8bit ports, port extender. I used the wrong term to describe the function of the chip.

Hi Scott (@rapid hornet), after your stream of February 9, I ordered two Lolin S3 and one Lolin S3 PRO boards via AliExpress. Yesterday they were delivered. Unfortunately the STEMMA/QT qwiic connector on S3 board that I received is not wired as shown in the schematic that Wemos publishes. The wiring also differs from the "standard" qwiic wiring that Adafruit and Sparkfun use. I discovered that the wiring of the +3V3 and GND in the STEMMA/QT qwiic connecter are reversed. I had to use a breadboard to correct it. I also had to use 2 external pullup resistors. Anyway: the Lolin S3 boards have the 2 USB connectors (UART and OTG). That's what you showed in your stream and that's what I wanted to try for debugging.

The adafruit_touch library is designed for adafruit displays. Adafruit_Button relies on drivers from adafruit compatible touch drivers.

It's not so much an issue with power draw as it is the fact that the voltage tolerance is very tight. Over any notable length of cable this becomes an issue.

- The foundation
- The fact that there is a big community

The project I'm playing with uses "GuitarML" which is something that uses "ai" to generate some models to emulate amplifiers and pedals. So what I would like to do is to port the guitarml to work on circuitpython.
So far if you want to add pedals, you need to recompile, and I don't work like that any more. If I want something, I want to just drag and drop a file (or to use the wifi workflow)

Raspberry Pi Foundation documentation is top notch.
Their docs are better than a lot of mainstream chip vendors. I'm quite impressed by the Pi Pico docs.

The pedal is open hardware, and has a git repo, and it's easy to make them. Then you just put a daisy on top and there you go.

Hi Tim and all present
clever summit
🇸🇪 👋
rigid crag
the backend could parse the URI and not pass in the netloc stuff
then it becomes a file like item
the http[s] is the scheme which is part of the netloc (network location)
scheme ":" ["//" authority] path ["?" query] ["#" fragment]
so the backend would only pass in the path to the module class
or your module would only reference the path part of what backend sends
waiting for you to page in the rest of your memory - no worries

Good morning ☕

Grab an old bundle release and take the mpy/folder from there, or are they all latest if v9 compatible?
Or is this an attempt at circup installing older versions
grand tusk
Hey y'all!
unreal bay
I found my custom bundle based libraries didn't identify a version (maybe git copies tho), and just always offered to update them with circup
sand lotus
I spent all last night to this morning updating my Fitbit project from 8.2.2 to 8.2.10. Because of all the nice updates since 8.2.2 it runs much better and I added some new features. I'm tired and might fall asleep.
rigid crag
always nice when version updates do good chaos
run a second terminal to force a circup to the board?
unreal bay
100%, get it out there.
Resolve version issues as a bug later

They say a picture is worth a thousand words. This shows why the Fitbit project has been a very important project to me. https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Boards/espressif/Unexpected Maker Feather S3/3.5 TFT Featherwing/Fitbit API Graph
rigid crag
^^ that's probably why it's referencing only the filename - it will rebuild the path later?
unreal bay
ah good spot
rigid crag
see line 297 - it has a os.join( ... library_path ... )
sand lotus
that's a good point
rigid crag
because it's only using the filename when the library_path is used that solves all the / \ stuff that breaks windows paths

when working with strings - you can put them inside of ( ) and break across lines

also useful for long If Elses like that module_name bit. The Slash is if it's not implicitly supported as a line break otherwise (the syntax)

does it create a new line because it's indented as a different line?

if (

or var3 == "blue"

and expected with broken indented strings or function arguments at matching indent level

I did not offhand, I was looking mostly for the dual encoder. Just a lot of googling and checking the big suppliers
sand lotus
Only the shaft is clear. Would be pretty hard to find one with a completely clear body. 😉
It's rotary encoder with an LED.
unreal bay
os.sep returns \ in windows and altsep = /, so it probably breaks on urls.
altsep fails on other oses
fancy pushing a WIP commit so i can run it on windows? or which branch you on?
no pressure, shout in a bit when ready
grand tusk
About to melt some solder. ⚠️
sand lotus
the spice must flow
rigid crag
all of that seems to be to extract the filename part, split out the extension and then look at that without having to know that it's a URL or a path
maybe say "key" instead of "name" so you know it's a dict key
unreal bay
that's a great idea. naming things can make such a different to the mental overhead of reading / working in the codebase
rigid crag
doing that is a hard requirement for me, just so I can prevent my future self from pain
try running url.parse() on the file reference - it should still return an object that has .path that will let you split out the basename
url = urlparse()
filename = os.path.basename(url.path)
key = ...
that should work for both branches
ugh, so hard to not be able to speak
no - you already have url
what I'm saying is that url.path is either the path of the url or the directory/file of the file
sand lotus
you have to use a variable for an f-string print to work. try print(f"test") and it doesn't like that
so making it default wouldn't make sense in all situations
unreal bay
macro at top of file or something, print hijacking, the ultimate sin 😇
rigid crag
it's all good - I've lived in the world of switching between URI parsing and os path parsing
you did work out exactly what I was trying to say
my past life was build/release for Mozilla
unreal bay
list command had some bad names returned, eg for toml library.
name in loop: toml
dev_meta in loop: {'path': 'E:\\lib\\toml\\', 'mpy': False}
module_name after 1st: toml\
name in init: toml\
path in init: E:\/lib\toml\
ParseResult(scheme='e', netloc='', path='\\/lib\\toml\\', params='', query='', fragment='')
e
path b4: E:\/lib\toml\
directory
file: None
name: toml\
unreal bay
sorry, more bad ones, it gave a trailing slash.
Yeah its called just toml
files Worked, folders didn't
rigid crag
I am thinking that the bug he just fixed will solve for folders also
as it's not using hack/smell if/else
unreal bay
I'm surprised it called the drive a scheme on windows (must be simple colon check to support gopher etc), I'd have thought it's be empty unless passed a file:///e:/ url
rigid crag
that pattern e: is older than windows - was also used for CP/M
unreal bay
CP/M?
grand tusk
USB Host featherwing ready to go.
unreal bay
oh A> maybe
sand lotus
A: and B: drives were reserved for floppys
rigid crag
yea, I have way too many OSs in my brain (CP/M VAX BSD UNIX LINUX)
sand lotus
which is why windows main drive starts at C:
rigid crag
(I'm 60)
rigid crag
yea, for a folder the name (key) would be the basename of the path I guess
I would rather you look for the presence of .mpy or .py and pick file else path
instead of using os.sep which is troublesome on windows
unreal bay
correct, now with fonts in bundle
rigid crag
the reason is on URLs it will be looking at \ if run on windows - would it not?
unreal bay
url wont have trailing slash if its a single module file?
ignore me, only 3/4's of the time got you on screen
sand lotus
USB Host featherwing ready to go.
Interesting soldering technique. Haven't seen that done before. You do risk with repeated use getting a little adhesive in the breadboard holes... better than dropping solder in one though.
I just put the pins in and tack the first and last eyeballing that they're straight. I don't solder them while in a breadboard but I like the idea.
hmm how long of a string would adafruitio accept? 255? if you chunk it you might be able to host an entire circuit python script from an MQTT feed itself. An impractical but interesting idea. 🧐
grand tusk
That breadbord is just for soldering.
sand lotus
I might pick up an extra breadboard just for soldering then. That's a good idea.
rigid crag
I can see why the original code was sniffing the scheme for http
itemSep = "/" if http in scheme else os.sep ??
^^ i.e. replace your hardcoded "/" with a variable that is set based on the environment
unreal bay
Then ask it to uninstall both at once via the web workflow 😉 don't fix it, delete via File manager - thats the advantage of web workflow
Add timeouts later
Yeah makes sense, low default timeout and a nice config option for those with slow connections or large files
rigid crag
default timeout is 300 seconds
default for requests over TCP I believe
that's coming from Click command line parsing (?)
unreal bay
Stream support i guess needs infinite timeout, or waiting for a process to complete
whats a timeout of 0 mean to the audience here?
rigid crag
snickers
unreal bay
it came up in the adafruit IO library
rigid crag
most will say 0 = no timeout, but in reality it ends up waiting forever
sand lotus
no timeout for requests might make sense so it can attempt to reconnect forever. makes sense for wifi.radio, not so much with requests.
unreal bay
Think we have a default timeout, but 0 means until you get your response or 60secs/default. Although in another context, it meant immediately return and update all the backend things with any new info, but don't block waiting for that new info (only accept if already received or ready on the wire)
Set a timeout on the webbackend so we can overload it through command line, use self.timeout everywhere
sand lotus
some people with bad internet or really laggy hops might need a longer timeout. allowing people to specify longer timeouts would help them.
unreal bay
legend, thanks ❤️
rigid crag
this is how Requests in CPython handles timeout now - to have the connect and read work different
If you specify a single value for the timeout, like this:
r = requests.get('https://github.com', timeout=5)
The timeout value will be applied to both the connect and the read timeouts. Specify a tuple if you would like to set the values separately:
r = requests.get('https://github.com', timeout=(3.05, 27))
yea, it's important to split them into different timeouts in complex code
