oh! you need to send an empty chunk

[brazen grove]

goodnight

[rapid hornet]

night!

http 1.0 doesn't do chunked responses

which are nice

[cinder wind]

right yes nevermind then 🙂

[rapid hornet]

could be C escaping

[cinder wind]

there's no escaping from C, Scott

[rapid hornet]

I think credentials: include will work if the html page prompts for the password

[cinder wind]

Scott had the actual working solution. I was just peanut gallery

[rapid hornet]

ah, so that should do it

the prompt is caused by the unauthorized response

I think so. was debugging while you went over it...

I did just get put working

[cinder wind]

thanks Tim!

[inner spade]

Thanks!

[rapid hornet]

nice work! thanks for testing this out

[inner spade]

‘Morning.

[grand tusk]

Hello.

[upper sandal]

yeah just add the name

it complains if the directory exists anyway doesn't it ?

hmmmm I would think it shouldn't be able to write to the drive, it's a matter of how it's mounted

C or python they should both use the same VFS

but 🤷

well I posted the link in the wrong channel, bu you found it anyway 😉

[inner spade]

Progress on the RGB matrix fader. Working with various displayio objects and group layers now. Also includes normalization and gamma options.

[upper sandal]

does that work on other screens ?

I don't think we can fade groups currently in displayio or ?

[inner spade]

Yes, designed to work with displayio objects on any screen. It’s adjusting displayio palette contents and object color attributes.

[upper sandal]

nice

[inner spade]

Trying to refactor it now for more general use. All in CircuitPython for now..

Envisioning an internal displayio object/group brightness feature at some point, but that’s a bit beyond my current pay grade.

For now, it’ll become a video mixer -like function.

An object or group can has its own instance, just like the demo’s background and foreground layers.

[upper sandal]

yeah I struggled to find something good

I settled for the python minify-html module and adding my own substitutions

I mean, that is a good minification of an empty page

meh it's valid enough

output = minify_html.minify(
    data,
    minify_js=True,
    minify_css=True,
    remove_processing_instructions=True,
)

that's how I used it

I think that's <??> and stuff

in the readme of the repo there is that mention of python interface:
https://github.com/wilsonzlin/minify-html#get-4
and there is that documentation of configuration options
https://docs.rs/minify-html/latest/minify_html/struct.Cfg.html

ah you have to click the triangle >

in front of the python logo

the readme file uses <details> html tags that I suppose are specific to github, so it's not really markdown

it shows .env at the bottom

ah ok

so is it all server side ? I thought the idea would be to have an API and have all the html/js be on code.circuitpython.org ? Or is it like just a minimal version when you don't have internet access ?

(or safe mode)

reset or boot on purple

oh no on yellow

sorry

purple is UF2

oh

storage.disable_usb_drive() ? or eject the drive from the OS ?

not clear on what "active" means

speaking of mpy files, if you feel like looking at the bundle problem after that
https://github.com/adafruit/circuitpython-build-tools/pull/88

the bundles are broken

the single-file libraries mpy contains the py source instead

https://github.com/adafruit/circuitpython/issues/6500
https://github.com/adafruit/Adafruit_CircuitPython_Bundle/issues/384
https://github.com/adafruit/circup/issues/146

oh haha

git fetch --tags or something ?

the bundle uses the pip version of circuitpython-build-tools

it was updated 2 days ago

but it had not been updated since december

yeah because there was no release of the windows change

apparently I'm the only one who noticed, not sure how to ring the alarm bell on that issue 🤷

Ooh, those are snazzy!

[dim wigeon]

They won’t continue to be the most popular microcontrollers if nobody can buy any… 🤔

[cinder wind]

ladyada now stashes all the precious chips under the mattress where they're safe

[dim wigeon]

I wonder how long it’ll be before someone gives up and writes a cycle-correct Atmel emulator for ESP32 or RP2040 or something.

[wraith thunder]

Adafruit seesaw is a really good concept, why not using attiny to replace MCP2300X fixed function I2C devices?

[sand lotus]

honestly didn't know an expander was available. i'll definitely try to pick one up as my next project will require a lot of I2C sensors.

get a grand central, oh wait lol. this is where we live now.

[viral sail]

Thanks and good night. 🌗

any idea when the esp32-s3 feather will be in? they sold out like hotcakes this week.

very cool techno art event

just realized after desk of lady ada it switched over to chip shortage from 5 days ago and i was talking to the past.

[robust horizon]

wild, that chip proposed by ladyada on the last Great Search can also implement some (limited) programmable logic -- e.g., you can make an output pin be the AND of two input pins, and more.

Thanks JP!

[ionic garnet]

yeah similar here in Sturbridge, MA but our New England weather can change in a split second!

As usual, I told a colleague not to scedule meetings at 4pm on Tuesdays. I told her "that's allocated time for me to spend money"

[haughty quiver]

sorry, didn't see this -- are you asking about how to calibrate it for the specific screen?

[queen sentinel]

Yeah, just wondered if you ran into any issues while setting up the ranges for a particular touch screen and what strategies you used for calibrating 0,0 and max,max.
Thanks, John!

[haughty quiver]

Right on -- I just did a simple stream of printing the values and took a little bit off of the min-max values to use in my remap.

It would be neat to write a calibration script like the Palm Pilot and Nintendo DS used to have

touch four corners and center, let it use those for min-max

[inner spade]

This could be adapted, I think. https://github.com/CedarGroveStudios/Touchscreen_Calibrator

Works with the REPL without a screen, too.

[inner spade]

@smoky island Yes, with a value of displayio.Palette.make_transparent(x) where x is outside if the palette range, it would occasionally cause a hard crash of the Matrix Portal distribution.

Scott mentioned a bug in https://github.com/adafruit/circuitpython/issues/6509#issuecomment-1162369015

Only occasionally.

Likely once in 100 iterations with a value of -60.

But I was messing with the palette contents at the time, so it could be a memory leak-like event.

So that’s good news that you can have multiple transparent colors in a palette. Somehow I missed that lecture day.

Thanks!

[haughty quiver]

ah, yes, perfect! I forgot you had made that, very cool

Isn't it playing tic-tac-toe with itself

[sand lotus]

actually there was a sequel and spoiler alert, joshua gets blown up

to this day one of the hardest things to do with a vocoder is replicate joshua's digital voice. the original settings on the synth were lost in time though people have figured out with a degree of certainty which synthesizer was involved.

[turbid hill]

I just read the wiki article on the sequel

wargames 2 is kinda grade b but does put a modern spin on continuing the story, don't go into it expecting a classic reprisal like the original.

[fast pike]

@cinder wind Nice cube. How did you route the wires out of the cube? Are the panels all secured to the 3d parts without gaps or is there some space to fish the wire out from the center of the cube?

[cinder wind]

There are small cutouts in the 3d-printed parts that let you route the wires. It's a tight fit and kinda fiddly but works. This pic sorta shows it (more pics on the printables.com page)

Basically you wire it up so you have enough slack in the wire length to let you move the panels around as you're screwing them down

Thanks Elias. I find Toggle switched very satisfying.

[ionic garnet]

Honest question: Y'all know I love and openly promote CircuitPython, but if writing an audio app that needed to run fast and efficient, say on RP2040, SAMD51/M4, ESP32-*, would you use C/C++/Arduino, MicroPython, CircuitPython, or even Rust?

My answer: lots of CP, some C/C++/Arduino, and recently Rust.

[lavish patrol]

@cinder wind 👍

Dynobot is not happy...

[ionic garnet]

@haughty quiver Is CircuitPython the right language for an audio app? Subjective I know

[sand lotus]

@haughty quiver the actuator switch used in the TR-808 is still available. https://www.mouser.com/ProductDetail/Alps-Alpine/SKHCBEA010?qs=6EGMNY9ZYDSpiXoBCBNuog%3D%3D

however the lever and key caps might need to be 3d printed, they've been discontinued about a decade.

i think the actuator key lada ada found are a great replacement, you can 3d print or perhaps resin mold new keycaps to replicate the 808 keys.

the only real difference between the one she found and the original is the length and color of the keycap.

if you combine the alps alpine skhcbea010 with some replacement parts you can build an original. expensive but doable. https://syntaur.com/keyboard.php?keyboard=721

that's the magic of open source 😉

[upper sandal]

every board with a stemma-QT port has board.STEMMA_I2C now

[inner spade]

TAPS versus TABS? Would ‘tabs’ create a conflict?

[upper sandal]

it's either an alias to board.I2C or a different port on the QT PYs that have both on different pins

oh yeah we disabled pylint's "consider using f-strings" because not all boards have them, but that's sometimes a good change

I think it might complain about %

also Dan managed to fit f-strings on all boards, but I'm not sure if it's in 7.3.0 or 8

[sick berry]

yeah, it warns you about it

to use the new f-strings (I don't mean they're new)

I think they added it on 1.19

[inner spade]

YW

Appreciate your fix

[sick berry]

lol

[inner spade]

Sometimes just dropping the display brightness to 0.1 works nicely with a camera

Perhaps 0.3? There may be some differences from board to board.

[main flame]

when changing projects from the Adafruit Learn Guide, how do you keep the article text & code snippets in sync with the full code?

As a very specific example, https://learn.adafruit.com/making-a-pyportal-user-interface-displayio/groups#hide-and-show-a-group-3052308-8 has the hideLayer and showLayer functions, but this PR replaces those functions with layerVisibility()

Would this PR require the article text to be updated? Do they just gradually diverge? Something else?

Thanks!

[brazen quail]

Hola from stormy 'rado. :-D

[upper sandal]

yes, named and numbered substitutions

and you can use a dictionary as the other argument

they are kind of necessary for localization for example

[brazen grove]

this is very useful when translating to languages that use different grammar than English and can have things in different order

[upper sandal]

to allow reordering arguments in the template string

**dictionary_name

[brazen grove]

prefix the dict with **

to pass it as keyword arguments

[upper sandal]

I think it works with a literal

[main flame]

does display.height and display.width respect display.rotation? Or do they assume rotation is 0?

[inner spade]

Yes, they respect .rotation

[smoky island]

Thanks everyone! good night! 👋

[sand lotus]

@inner spade so does the TFT featherwing which isn't a bad thing unless you're using a board like the nrf52840 sense that has an on board temp sensor that it'll throw about 10F higher than the real ambient temperature. The temp bias doesn't compensate. I've learned if you're going to use a large TFT don't use it with a board that has on board sensors, better to use SPI or I2C stemma sensors.

pyportal and tft featherwing + feather have the same issue.

[sand lotus]

I actually visited edmund scientific when I was a kid living in NJ. Unlike the amazing catalog they were known for, (like Sears catalog or Toys R Us catalog except for kids science projects). The actual store was more like a weird combination of a military surplus + science and robotics stuff, not what I was expecting but was still impressive. Adabox is definitely similar to some of their science project kits. One of my first memories of Edmund Scientific was a cub scout project using AA battery packs, potentiometer, and motor to make spinning art... very similar to what you'd find on Adafruit. Trust me when I say Adafruit is now 1000x more advanced than Edmund Scientific ever dreamed of becoming but you'll find their name comes up a lot due to 1980's and 90's nostalgia for science and technology learning.

[smoky island]

Getting started now working on the Game & Watch Octopus game on todays stream. Hang out here in the chat and follow along on YT: https://www.youtube.com/watch?v=3ehwI0sY1dU or Twitch: https://www.twitch.tv/foamyguy_twitch

[inner spade]

Yes, I only use external sensors for measurements that are critical to the project. However, one of my projects also uses the on-board temp sensor to reduce TFT backlight brightness and turn on a small fan for cooling the enclosure.

[sand lotus]

oh that's a neat idea and one that is probably what an on-board temp sensor is truly for. i guess it's just the way it's marketed when i bought it thinking it would be an easier built-in way to read ambient temp. yeah i was wrong.

[inner spade]

Very cool. Like Edmund, Adafruit’s catalog is a dream factory full of project ideas. Their learning guides take it to the next level.

[sand lotus]

yup between the learn guides, RSS/blog posts, and hackspace magazine there's always something to keep the noodle groovin

and of course the discord is a constant source of inspiration and learning. lots of cool stuff happening here every day.

oh and can't forget the youtube videos, which i binge watch by category from time to time 😛

oh foamyguy is live now doh. on a saturday?

[clever summit]

Hey Tim and chat.

[inner spade]

Could have some scrolling text that encourages the game player — in Pirate, of course.

[sand lotus]

turn dithering off, unsure if your program has that. dithering is part of what creates some pixelation.

[inner spade]

It’s his usual Twitch stream.

[sand lotus]

i usually don't tune in on sat. had no idea. very cool.

yeah it might look pixelated after a scale but during export disable dithering will clean that up a little

dithering is kind of like anti-aliasing

[clever summit]

I am quite sure I actually played that game at some time in my life.

I still don't understand how you are able to talk and program at the same time.

[inner spade]

Context switching. Something I aspire to develop someday.

[sand lotus]

everyone going ham on the 60% keyboards but i can't live without my numpad and media buttons. like you have a full pc why limit yourself with a tiny keyboard. :/

that would take a long time to get used to

yeah that makes sense... also means you're going to be kinda lost without your keyboard. like going to a school lab and all of a sudden you're typing nosedives to 10wpm 😛

[clever summit]

Using a 60% keyboard is like using only 60% of your brain.

I feel the same for using just one monitor.

Lol

[sand lotus]

lol

sounds like a good way to give yourself tourettes

[inner spade]

Some tentacles could be part of the background then covered by a masking polygon layer (one graphic object) that changes size.

[sand lotus]

would it run faster using a polygon mask that updates its shape through math vs tilegrid icons?

[inner spade]

Each item in the group is indexed , so the list of dictionaries may not be needed

[sand lotus]

"Break your code into sections and use the combination of gc.collect() and printing gc.mem_free() to identify how much memory is used in each section."

not optimizing if it works is how windows os got to be like 10GB 😛

is for a learn guide? yeah beginners aren't going to want to mess with gc

which is me. i've never used it before. i'm learning new stuff.

[inner spade]

Also, given all the retro LCD games out there, documenting your approach to make the octopus game will be applicable to making others.

Very similar to your Winamp project approach.

[sand lotus]

that winamp player is sick. i made a winamp skin back then, fond memories. great player.

[inner spade]

For spritesheets, I usually draw a numbered grid in GIMP then cut and paste into that framework.

Makes it easy to test with just the numbered grid before pasting in the graphics.

[sand lotus]

you can do that with a script in photoshop, unsure about gimp

[inner spade]

Maximum headroom

[inner spade]

Wow. That has the LCD game look!

Some of the games had contrast issues that revealed the display ghosting. That would be a nice optional effect.

Just need numbers

Here’s a seven segment font that could be handy. https://github.com/CedarGroveStudios/SevenSeg_font

I manually created this font. Could easily modify it if needed.

It’s just numbers, punctuation, and hex alpha.

Line 15

[sand lotus]

that looks great cgrover

looks real

[inner spade]

Thanks. Really wanted that bubble LED look.

Was for an HP-35 calculator emulator.

[sand lotus]

is there are size limit to a bdf if i want to make my own?

[inner spade]

Don’t think so. It’s just a text file underneath.

[sand lotus]

the temp display on my tft is like 100 pixels high and looks really pixelated when scaled up.

nice. couldn't find any really large ones. biggest one i could find i think was about 36

yeah i'm going to have to make my own if i want it to look clean really big.

[inner spade]

A large seven segment digit could be built from a sprite sheet.

Then just repeated.

[sand lotus]

just checked and the fonts i'm currently using are BDF

i think cgrovers font is perfect for your game

have a great day, looking forward to seeing how your project shapes up

[inner spade]

Thanks for the stream. Great project! Appreciate the opportunity to learn some new stuff.

[inner spade]

@smoky island Just found gimp->image->configure_grid — hoping that’ll help when editing sprite sheets.

[sand lotus]

The AVR-IoT Cellular pins are staggered. How is that feather compatible, the pins won't line up. Why would they stagger them like that instead of making a straight line of GPIO holes? Would you have to break pins down to each individual pin to solder them in or will a row of pins fit in there even though they're staggered like that? Is there a reason for staggering them like that from a PCB design perspective? I prefer the straight rows of the feather design even if it's only for aesthetics.

[vivid ore]

My guess is that the staggered holes allow for a tighter tolerance with the header pins, considering they do seem to include straight header rows. It may look funky, but if you consider the size of the pins vs the size of the holes, it's actually pretty brilliant in my opinion; they can help align the pins more tightly without any external support or smaller drill sizes.

If the pins themselves have a strict enough tolerance, it may even be possible for the pins to make sufficient contact with the holes to even bypass the soldering step...

Ah, @sand lotus have a look through this: https://www.sparkfun.com/tutorials/114

[sand lotus]

@vivid ore Thank you, that's exactly what I wanted to know. It's just confusing to look at.

[inner spade]

@smoky island Since the tentacle segments all have identical color palettes, would it save memory to use only one palette object to associate with the bitmaps in TileGrid?

Would make it easier to control palette contents when manipulating the collective image, too.

Like when normalizing and adjusting for gamma.

Is the background color overlay in front of the black LCD segments or behind or both? Did they get fancy with those printed layers on the original unit?

Ah the colored layer is on top.
So again, the beauty of CircuitPython is that you can repeatedly tweak the graphics layout and immediately see the results.

You could create layers for the green and blue.

Take the background later, make the backlight color transparent and use it as a layer. No need to create separate color layers.

The color overlay has shadows too.

Thinking about how they manufactured it. The printed color layer appears as foreground with its own shadow. The shadow created a sort of 3-D effect.

Looks very good. Thanks!

@upbeat coral Do you have broadcast announcements enabled?

[shell mason]

was perhaps for the 3d hangout

[upbeat coral]

No. But I did know that there would not be a Ask an Engineer tonight and JP spoke yesterday as though all else was as planned (3d hangout, S&T).

[sand lotus]

i always look forward to watching show & tell even if I don't catch it live.

[hard hollow]

hey folks! if anyone wants to join in, here's ze link to streamyard https://streamyard.com/22bnrtyb27

[sand lotus]

aww so cool, that's like the cute robots from that movie

batteries not included that's it

[opaque hearth]

like a 3D Hangouts in the PM

[sand lotus]

Jayy's robot has the potential to scare me more than lars.

[cinder wind]

What's a Wokman? It doesn't look like it can make stirfry

[nova totem]

mmm stirfry (I really need to eat)

[sand lotus]

it can chop suey samples tho

JP's got it hooked up to soft synths now. watch out.

[inner spade]

@haughty quiver So very cool. Could you use one of the DACs to gate or adjust the recorder's speaker output?

[alpine nova]

i love vcvrack!

[sand lotus]

so liz hacked the motor controller to create a... motor controller with a microcontroller?

[nova totem]

I vaguely recall that fisher price deck

[opaque hearth]

Style points for the big yellow crank!

[inner spade]

@split gazelle Love the aesthetic. Will the capstan-driven tape loop work if the motor runs in reverse?

[sand lotus]

yeah definitely reminds me of that fischer price tape player for some reason

[haughty quiver]

i wanted to use one of the DAC channels for gating it, but couldn't come up with a good way to control the volume pot. Any suggestions?

[split gazelle]

yes! as long as both wheels are in both directions were working

[haughty quiver]

I'd be OK adding a digital pot for volume, too @inner spade

[inner spade]

Might easy to gate by over-biasing the input to the output amplifier post-tape head preamp. Do you have a schematic?

[smoky island]

Great idea using feathers communicating with each other and checking for power in different outlets awesome job John!

[split gazelle]

super cool @nova totem !

[inner spade]

Yeah, might be the best approach. Probably the least invasive.

[haughty quiver]

@inner spade I haven't found a schematic yet. It's a GE 3-5362A

[hazy tiger]

thanks! It was a super simple project and hopefully its helpful! 🙂 Codes up on github: https://github.com/thinklearndo/circuitbreaker

[sand lotus]

would be great for a watch project

[cinder wind]

woohoo!

very cool @nova totem !

[nova totem]

Thanks, managed to get it done faster then I thought, math was not as scary as I thought

[viral sail]

Thanks everyone and good night. 🌑

[alpine nova]

that round display is sweet

[sand lotus]

yeah where can i find that round display?

[upbeat coral]

Thanks to all for sharing with us.

[nova totem]

Thanks, your examples were helpful to get started

[sand lotus]

great show everyone 👋

[alpine nova]

no aae today?

[nova totem]

I found them on aliexpress. I'll look up the name

[dim knot]

​No Ask An Engineer tonight.

[sand lotus]

no

[alpine nova]

ok thx

[hard hollow]

great projects tonight folks! have a good evening 🙂

[smoky island]

Thanks Noe and Pedro and everyone who shared great stuff tonight! 🎉

[cinder wind]

Thanks @hard hollow! Thanks @rocky reef !

[alpine nova]

thanks y’all. those were very inspirational projects tonight

[nova totem]

The round displays are "1.28 inch TFT LCD Display Module Round RGB IPS HD 240x240 Resolution GC9A01 Driver 4 Wire SPI Interface Adapter Board"

[inner spade]

I couldn't either. Sounds like the digital pot may be the best approach.

[nova totem]

There is a community library for the GC9A01 driver that runs the display. The resolution is 240x240 but the corners obviously do not exist

[cinder wind]

you get more resolution with a DAC (most digipots are only 128 pole)

[haughty quiver]

another thought is to use the speaker line out instead of the headphone out, and somehow gate that?

(there's a small speaker built into the case)

[inner spade]

Does VCV rack have the ability to gate audio signals?

[inner spade]

Another on/off gating method would be to light an LED coupled to a photoresistor with a GPIO pin -- to gate the headphone signal.

[sand lotus]

i've never played around with vcv rack but just looking at how big the synth is i'm sure theres a way to gate, i mean just look at the size of that thing ;P

[haughty quiver]

Ah, gate in Rack isn’t my question, it’s about how to have the walkman output gated with hardware

[sand lotus]

decouple the tape head?

that would take too long mechanically if you wanted a high speed gate

a normal gate should be easy with a volume on/off switch controlled through digital or analog out pin.

it would be a straight cut gate, but a gate is a gate.

[inner spade]

@haughty quiver @cinder wind I used a 256-step linear digital potentiometer for an ADSR on a project a couple of years ago. Resolution artifacts didn't seem to be an issue, but I played in a rock band for a few years... Perhaps a logarithmic digital potentiometer could work even better.

[haughty quiver]

that's great, I also love your vactrol gate suggestion 🙂

vactrols always have a nice, syrupy envelope to them 🙂

🥞

[inner spade]

Just the idea of a vactrol feels soothing and organic, doesn’t it?

I suppose you could PWM the LED and smoothing capacitor if you wanted an analog-like response.

[ionic garnet]

Dropping in to say HI @haughty quiver and all you AdaLovelies. I will miss this today. 4 more hours of meetings. Busy day. Some very interesting meetings though. LifeOfACTO

Good afternoon

[lilac tusk]

Dyslexia is great because I’ll be scrolling through twitter, see John Park’s workshop and my brain stops working and goes Pohn Jark’s workshop! It’s great for a laugh every once in a while

[smoky island]

Sometimes I’ll just roll with the dyslexia because my brain has already formulated the sentence wrong. Makes communication extra spicy

Anyway, happy Thursday everyone!

Raspbery Pi Pico W - now in many flavors - chocolate, vanilla, strawberry...

[lilac tusk]

You say strawberry and it makes me think of cloudy with a chance of meatballs

been thinking of a diy solar light around the house. that probably would have helped towards that

[glass stag]

I think I will wait for the Raspberry Pi Pico USB-C.

Been playing with Inkscape today. 👍

[lilac tusk]

Weird.. tried to share a picture of my rp2040 board

[smoky island]

Super cool! I didn't know there was a converter for SVG -> vectorio. Thanks sharing that @cinder wind and JP for showing how to use.

[lavish patrol]

Cool

[shell mason]

https://tenor.com/view/batman-robin-and-im-bat-gif-20652919

[lilac tusk]

Need to let it cool down I guess

[cinder wind]

it's not exactly a SVG, it's more like: a list of x,y points created from an SVG

[lilac tusk]

Either way, JP will probably have some high flying Pico based adventures coming up

[dense marlin]

Thanks for dose guides.

Nice little EuroRack setup.

[grand tusk]

I think you could you make a vactrol with two LEDs?

[sand lotus]

i think it's called an optical switch. opti-... something or other

[shell mason]

https://tenor.com/view/synthesizer-modular-richarddevine-technology-music-gif-13423466

[cinder wind]

Vactrol gates are a great DIY project if you're getting into modular synths. Here's one example https://www.youtube.com/watch?v=8BOnvSQpoGY

[shell mason]

cool Todbot

[sand lotus]

the first step in a DIY sequencer. timed gates are steps in a sequence. 😉

aha, see 🙂

[spiral vale]

late to the party

[shell mason]

https://tenor.com/view/cute-dancing-party-dj-minion-gif-3478410

[sand lotus]

sequencers are a beautiful thing

gate is basically pull_up and pull_down 😛

i still think trying to decouple the tape head with a mechanical piston switch really fast would be oddly satisfying.

[grand tusk]

loose wires

[spiral vale]

dont anger the cassette

[grand tusk]

Someone's phone is ringing.

[shell mason]

CircuitPython Casette player

[sand lotus]

didn't know those kind of optical switches were in synthesizers. cool lesson

[dense marlin]

Are there other cassette players that could be recommended? The GE 3-5362A is not available so wild in Europe.

[sand lotus]

JP's thought all of this out really well.

could use a pcb with some solder. 😉

[tender wolf]

Here’s my WIP Cassette build

[sand lotus]

great demo, you'll get it all sorted out eventually JP. it's coming along nicely.

[cinder wind]

the sound engine causing CircuitPython crashing is so frustrating for me

key yer on? okeyron?

[sand lotus]

What is seesaw? --> "Adafruit seesaw is a near-universal converter framework which allows you to add add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be configured to give a wide range of capabilities"

[tender wolf]

is the gain value implemented like a gate? sounds like it activates after you turn the knob then press the button

that explanation just answered my question

[sand lotus]

I2C = I squared C. Seesaw is a play on the letter C. Easier way for me to remember it.

ohh i'm definitely going to pick up some of those switches when they get stocked!

always look forward to the music stuff JP and Liz are doing lately. really cool stuff.

[cinder wind]

this thing I think https://www.hackster.io/news/retro-audio-player-with-modern-functionality-f6a0b2653d4c

[lavish patrol]

Neat.

[glass stag]

Reel-to-Reel LCD's would be cool. How big do the Adafruit round TFT's get?

[grand tusk]

It's cute!

[sand lotus]

great design!

[grand tusk]

Thanks JP!

[dense marlin]

Thanks, great Show again.

[lavish patrol]

Thanks, @haughty quiver 👍

[viral sail]

Thanks @haughty quiver

[inner spade]

Thanks @haughty quiver !

[smoky island]

Yep, Deep Dive tomorrow evenning. Thanks JP Great Show 🎉

[shell mason]

modern casette drive could have features like if tape get stuck

[haughty quiver]

thank you all for hanging out!

[glass stag]

Great show. Have a good day all.

[dawn iris]

I got there late

😦

[drowsy inlet]

thank you!

[grand tusk]

Thinking about using a watchdog timer to detect stalls in my 3 node RP2040 cluster. I'll have to consider adding the power of W.

[shell mason]

all the fine controls now what maybe in the back in the days was guessing work

[sand lotus]

@dense marlin any casette player with a volume and speed control potentiometer will work as they'll both be electronically controlled.

[dense marlin]

Thanks.

[haughty quiver]

i think Sony TCM-353 may be a good choice for you, seems available on German eBay and has a speed control knob

something to look for in searches is "dictation recorder" or "voice recorder" as they are more likely to have a variable speed switch or pot.

[dense marlin]

Thanks @haughty quiver, I will have a look.

[brazen grove]

there is sound now

[inner spade]

Sounds good on YT

[upper sandal]

H is headers

they actually have a different PCB without the castellations for the headers version

the wifi module's API is apparently under NDA 🤷

[left pier]

👋

[brazen grove]

classic rpi :)

[upper sandal]

I didn't verify that information though, I didn't look at the available docs

[brazen grove]

I will stick to the open source hardware, thank you

[upper sandal]

what they say in the news is:

The network stack is built around lwIP, and uses libcyw43 from Damien George (of MicroPython fame) to communicate with the wireless chip. By default, libcyw43 is licensed for non-commercial use, but Pico W users, and anyone else who builds their product around RP2040 and CYW43439, benefit from a free commercial-use license.

[brazen grove]

for me it's not about how much they are doing — I agree that community-wise they are great — it's about future-proofing my own projects
