@cinder wind For when your desk is in the corridor..

[teal river]

Getting to where JP is explaining ortho keyboards vs. non-ortho, about how it's not really harder to learn [or maybe re-learn if you know QWERTY], but I'm afraid to switch from QWERTY because I know I'll still need QWERTY for other machines and other people, so I probably would never be as good at 2 types as I am at just QWERTY

[waxen thistle]

Would love to see these in pin/pin configuration: https://www.adafruit.com/product/5152

Nope, no screaming here. Unless a Lars sneaks into my workshop, then well....all is lost.

[clear matrix]

Lars has no need to sneak. Lars is simply always everywhere.

[teal river]

Can I use Lars to make an Untitled Lars Game?

[lavish patrol]

Worse still, he'll bring Goose with him.

[waxen thistle]

oh dear.

[clear matrix]

Indeed.

[lavish patrol]

Lol

[keen fern]

Is there any reason you could not attach the headers with the pins going under the board? This would keep the square format without having pins hang out.

[teal river]

No reason you can't, just messier with wires crossing each other

Only place we're allowed to panic is at the disco. Or so I've heard.

[lavish patrol]

Lol

[teal river]

I panic everywhere and always

[lavish patrol]

Why am I now thinking of pancakes?

[teal river]

Because you're hungry and pancakes are delicious

@cinder wind The first one is always a dud.

[waxen thistle]

Thanks @haughty quiver for another excellent workshop! Hope all that makeup came off easily last night 🙂

[woeful pond]

@haughty quiver Great points. Thanks for the show

[teal river]

@haughty quiver Are you interested in an Untitled Lars Game becoming a thing? And can I use your face for it?

[lavish patrol]

Great show @haughty quiver 😀

[cinder wind]

[inner spade]

Thanks @haughty quiver. Very creative costume and makeup for today's show.

[haughty quiver]

Right? Thanks @inner spade it's my "human person of this, your Earth" look.

[waxen thistle]

Very convincing.

[haughty quiver]

It's the eyebrows. You humans mostly all seem to have them.

[waxen thistle]

So that's the secret.

[waxen thistle]

rejoices

[lilac tusk]

It could be the goodest bad thing to every happen

[teal river]

This is the point at which I abandon this timeline.

[waxen bough]

Too late for the workshop and maybe this has been pointed out about the ortho keyboard spec. When one thinks about coordinates as x,y, you think horizontal, vertical. But when one thinks about row, column, you thinks vertical, horizontal. The keyboard is row, column (also think about the scan pattern for the pixels)

[sudden slate]

I'll catch up on the stream - picking up family 🙂

Random meta question about the stream: How do you feed the sony camera into your computer to get it into the stream? It plugs in with USB and has a driver or something?

[simple fractal]

today i biked to the gym, did an outdoor workout, biked home. busy

[nova totem]

about 95F (35C) here today which is crazy for us. and still no rain which isn't great

[clever summit]

@smoky island It's a webcam driver - https://support.d-imaging.sony.co.jp/app/webcam/en/

Hi Scott and everyone from Lisbon

[waxen thistle]

Good afternoon all you wonderful waders, snorkelers, and deep divers! 🤿

[teal river]

I walked about 4 miles, MapMyRun on my iPhone stopped recording part way thru, and my Garmin watch apparently forgot the walk in its entirety... screams into pillow

[waxen thistle]

Just got off a work call, hope y'all are doing well.

[teal river]

Ah, no, Garmin did not forget, watch just being dumb and slow

[queen crystal]

[smoky island]

Ah that looks neat, but lists support for only Windows / Mac though.

[waxen thistle]

@rapid hornet What was the deciding factor for the magewell vs. the elgato offerings?

[clever summit]

I use the webcam driver. Works fine except in MS Teams.

[waxen thistle]

That works too 🙂

my laptop seems super slow. which is weird

[waxen thistle]

oooo yes, some pacific nw salmon. i miss that and the crabs from pike place market.

Yup! There'll be an ama on friday next week!

[simple fractal]

not quite Pompeii levels but still

[modern night]

(I was behind on other work and don't have the announcement written yet)

[nova totem]

Yeah the interior of BC has been crazy. Most of ours is staying on the MB/ON border but drifting depending on the wind

[modern night]

It'll be a pinned post on the main page of r/python

[smoky island]

it's less official capacity, but I'm planning to stream at 11am Eastern on CircuitPython day as well.

[waxen thistle]

If you see a blue police box or a british-sounding Asgardian wearing green while in Pompeii....run.

Just don't cross the streams ~Egon.

i work on a python-based GB emulator, if you want to talk more about that. Sounds like a cool project 👍 probably too slow for circuitpython but yeah

[left pier]

BLE Trilaterilation or HAM Radio fox hunt stuff ?

[modern night]

ulab has a lot of the math functions you'll need for those projects

[grand tusk]

ah, math

[queen crystal]

As a game boy cart, you have to embed the nintendo logo for copy protection right?

[modern night]

BLE Trilaterilation is on my shortlist of projects for my home system--do you have a recommendation? (ugh typos)

[teal river]

I'm working on a Game Boy type thing, got one of those nice big Sharp memory displays from JP's Pick of the Week

[left pier]

I worked on a project where we did this... someone else brought the formula, but I think they just googled it, read some research and wrote it up.

[wind spoke]

This is the gameboy gamelink: https://www.youtube.com/watch?v=KtHu693wE9o by stacksmashing.

Unexpectedly in the house !

[modern night]

To a degree I just want to see what I can do with it, if I can manage it. Who know's if I'll be good enough to make it work but it'll be sweet to try

[teal river]

I deleted a sphere

[queen crystal]

PyOCD does use the JLink software, where as OpenOCD talks to the Jlink directly as far as I know.
For my JLink education edition for instance, it will pop up the daily warning window

But I have been enjoying using PyOCD a lot!

[cinder wind]

I already have OCD about Python why do I need PyOCD

[nova totem]

I am with you just kinda want to see what's possible with beacon tracking and location tracking

[simple fractal]

i can't find mine. its in abox under a box next to some other box

i have a number of original jlink and some mini ones.

[limber parrot]

I'm 'adam jones' from yt chat, thanks for the info on these positioning systems, i'm in the research / note taking phase so this is all super useful!

[simple fractal]

i do the same @limber parrot . i collect links with pinboard and then start working

[queen crystal]

Feel like saying "roll my own OCD" is almost like saying "roll my own crypto" 😁

[simple fractal]

not sure what fast means. i used the mini edu jlink to flash nrf feather boards. seemed ok

[timid plover]

is this python code talking through the JLink ?

[teal river]

Hooooonk screech someone almost had an accident

[oblique jay]

Ohhhhh 2 way stops are so bad people always get confused lol

[teal river]

Gotta go fast

[teal river]

People are dumb... All way stops say ALL WAY. People here just don't stop regardless

[oblique jay]

In code I think they call this “problem originates between keyboard and chair” 🤣

[limber parrot]

honestly, this seems like it is exactly what i was hoping for and looking for! Thanks!

[teal river]

Lol, I prefer PEBCAK, Problem Exists Between Chair And Keyboard

[oblique jay]

There we go hahaha I knew there was a better way to say it

[teal river]

"It's hiding"

[oblique jay]

I’m fascinated by how many types of debugging and analysis can be done!! Definitely a bit above my depth for now but I know it’s coming heehee

Getting to know my Analog Discovery 2 will get me working with all sorts of low data flows like that -

[teal river]

There's nothing scarier than when you have a memory leak, and you watch usage jump by about 250MB per second.... even 128GB runs out fast in that case!

[modern night]

Aw I want the glasgow so bad. I'll wait, but I'm looking forward to when the shortage is done

[waxen thistle]

After getting an Analog Discovery 2 at the pre-increased price, a friend of mine sold me their old ADv1. So now I have two portable do-everything devices 🙂

[timid plover]

i vs. {reg}

[oblique jay]

I went ham and got the extra breakouts and the box of learning chips for $50 as well ☺️ totally gonna work thru the xlinx course and am never gonna take parts out of the kit, it’ll be my “build a test thing” kit so I know what to order with some stuff I’m familiar with ☺️

[teal river]

My Adafruit order has arrived :D

[nova totem]

Your adabox?

[teal river]

That actually came earlier, this is just a regular order

brb!

[maiden lily]

yeah weird embedded memory bugs are a huge pain

[nova totem]

or make a random comment or print and hope the memory error goes away 🙂

[balmy tinsel]

So much love for rust. I'm really excited to see where it'll be in another couple years.

[maiden lily]

i think i stayed up til 3 the night before an international flight once looking for a stack corruption bug that turned out to be a space at the end of a max-length string

[modern night]

Rust and fortran are my two languages I want to learn next. But I've said that of fortran for years so who knows if I'll sit myself down and learn any time soon

[timid plover]

if you have a .elf file - objdump -S or -D

oh - you got it

[cinder wind]

I get those instagram messages all the time

[lilac salmon]

I got one of those instagram messages. I don't have an account at instagram.

[maiden lily]

sorry, i'm not paying a ton of attention--is it jumping to an unexpected address or something?

[waxen thistle]

[yay, I'm back. gotta love 6pm phone calls]

[teal river]

USPS: package delivered in/at mailbox
Adafruit box: on front step

[waxen thistle]

I nabbed two sets of most of the breakout boards, adapters, etc. That way I could mirror the setups if I needed it.

And then maaaaaybe a Digital Discovery fell into my shopping cart too during Black Friday

[timid plover]

which memory are you trying to ensure is not being corrupted, Stack, Data, BSS, code?

[waxen thistle]

I didn't get the chip kits or the learning courses they had, though it was tempting

[teal river]

Someone trying to hack Scott D:

[lilac tusk]

Nooo

[oblique jay]

The PPK was supposed to be good enough for me haha but the AD2 was just tooooo good 😊 I wanna circuit bend and do vintage game mod stuff on the side from my main project and needed a scope no matter what, but also really wanna “eat my broccoli” and get a really solid EE foundation to build on so I can work faster 😁

[teal river]

Halt and catch fire

[waxen thistle]

Yep, and the AD2 (and AD1, which is like 99% the same) are excellent value portable units. Their higher end portable units they released earlier this year are intriguing, if a bit cost prohibitive for beginners.

And I nabbed a PPK back in late May when they restocked, since I missed them during the end-of-year restock.

[teal river]

How do you get the not equal sign? I'm used to using !=

[cinder wind]

Do you have another device to compare against? (to check bad RAM)

[timid plover]

anything is possible, but it is rarely the hardware 🙂
do you have a second NRF board?

[teal river]

Hardware problem may not be the most likely solution, but it's the easiest to test!

Fancy font :O

[queen crystal]

font ligatures, some fonts have them

[simple fractal]

or there is some other font that replaced it

[waxen thistle]

like double lowercase ff having the horizontal piece connected between them

[spent way too much time implementing OpenType]

[simple fractal]

i think i use cascadia now

==

https://www.slant.co/topics/5611/~monospace-programming-fonts-with-ligatures

thanks for the ligatures comment. couldnt remember what they are called

[queen crystal]

I personally use Jetbrains' open source Jetbrains Mono font, which includes ligatures: https://www.jetbrains.com/lp/mono/

[waxen thistle]

Don't even get me started about paragraph properties when working on complex script (hebrew, arabic, etc).

You start asking questions like: "Where's the relative-margin-location if it's reading right to left?"

[queen crystal]

Quite a few, wouldn't know how to write all of them!

[simple fractal]

i had an argument with someone looking over my shoulder and complaining about the lack of space btw == and === and whatever.

[waxen thistle]

And thanks @simple fractal for the fonts link, I need to update my programming font -- whole "I need a fresh coat of paint on my life" sort of thing.

[left pier]

I think a whole deep dive could be on code editor themes and fonts ...

[maiden lily]

what are the types for that struct? Maybe a type misalignment?

[timid plover]

assuming the struct is static - and not moving - since it is in the link map

what are the variables immediately before and after - ( but it's not getting trashed - in that pyOCD doesn't report a change )

that was unexpected!

[teal river]

I have no idea what to expect because I have no idea what's going on XD

[timid plover]

did you have a code review that you wanted to do during the stream ?

[maiden lily]

is this what you were seeing before?

i too like to suspect the compiler when i make mistakes. I've never been right

[cinder wind]

here's a dumb question: what's best way to do enums in CircuitPython?

[drifting arch]

@rapid hornet https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/adjustment-of-ram-and-flash-memory << any help?

[teal river]

I have a TFT bonnet that uses GPIO 4, and the LiPo SHIM... Which also uses GPIO 4. What do I dooooo?

[timid plover]

right - need to use the link map 🙂

[left pier]

So.........
I was watching you use the Saleae in some older episodes ... you mentioned your own analyzer project have you had time to think about that all recently ?

[upper sandal]

is that the link ? https://github.com/gamblor21/rp2040-logic-analyzer/

[nova totem]

I had the RP2040 going, and @light stump got it hooked to sigrok

I had it output a CSV that I saved via PuTTy that I could load so a bit clunky

[waxen thistle]

@rapid hornet Is this the magewell you have? https://www.bhphotovideo.com/c/product/1332445-REG/magewell_32040_usb_capture_hdmi_plus.html

awesome, thanks 🙂

[cinder wind]

it's the one I have, but if you don't need HDMI passthrough, audio input/output, or many resolution choices, the $20 HDMI dongle is really close in quality

[left pier]

Hey if you're going to text you have to share your screen with the whole class

[teal river]

Guests :O

[waxen thistle]

I've nabbed one of those dongles via ebay before they were on adafruit's store -- and they're.....well, fine. The Elgato usb capture stick is marginally better. I'm pretty impressed with what Scott is using, looks a lot sharper than the alternatives.

[timid plover]

it does seem like a good idea to use the CPU hardware to help debug the problem - we are still trusting the CPU, right?

[cinder wind]

@rapid hornet is this all before interrupts are enabled? (like no other code can run in spite of the while(true))

[timid plover]

so why was the first word reporting the "*" difference ?

[drifting arch]

@rapid hornet I think the first 8 bytes or something is not 'user memory' but is something internal that the MBR or soft-device uses...

I've never used NRF before this...so I don't know if I'm talking bull 😉

https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/adjustment-of-ram-and-flash-memory

[cinder wind]

yeah the $20 one only does 720p I think. And Scott's Mr HD here

[timid plover]

you are getting close to your hard stop 😦

What are your plan for today?

[smoky island]

Working on some CP7 breaking change updates. First ulab and then looking in the Turtle library

It is customary to import numpy as np.
I think you might want to do import ulab.numpy as np.

That paste problem is odd.

I should get a PDM microphone breakout. The Ukulele project looks like so much fun!

Off to Spanish Fork. I'll have another look at the digital filter later. Thanks!

Maybe I can run it on the FunHouse.

[lilac tusk]

Spanish fork Utah?

[teal river]

Is that near Spanish Spoon?

[lilac tusk]

I wonder how many places in the US are called Spanish Fork

Probably a lot

[teal river]

I never heard of Spanish Fork before this, lol

[upper sandal]

I probably mentioned circup, I use that a lot

[teal river]

Sometimes I think about starting my own town out west and naming it "Philadelphia, PA" but have it in Oregon or something, so it'll be "Philadelphia, PA, OR", lol

[lilac tusk]

Spanish Fork is a city in Utah, south of American Fork

But I wonder now if there are other places have the name Spanish Fork

[teal river]

Why do we have places named with the convention "(nationality) + (utensil)"? XD

[upper sandal]

I mean...

actually when I see "City OR" I think "missing operand"

[lilac tusk]

Lol

[teal river]

XD

[wind spoke]

Did you talk to @opal fulcrum before working on those guide?

[manic vessel]

Try removing the ulab.filter import and see if it runs.

[wind spoke]

I was wondering in the car if there was some trick like import ulab.numpy as numpy

and then do numpy.x rather than ulab.x

[wind spoke]

Now we will see if you have a pulse...

I got mine too, but I dunno how I feel about them being required

[raven hawk]

from what I have read you can get a huge viral load even being vaccinated that will infect tons of people you yourself may not be hospitalized because of immune response

[ionic garnet]

same with me. Got my vaccines. But don't know about passports and all that

[teal river]

Yeah, you could become a carrier with the vaccine, even if you don't get sick... virus scary, staying inside

Haha, those look like those bar shades from the 80s

[raven hawk]

yeah those are funny

[teal river]

Are those two bottom slats empty?

[drifting wyvern]

What a nifty idea

[teal river]

That's pretty wild, I love how they line up

[raven hawk]

what program is ladyada using?

[drifting wyvern]

Eagle cad?

[teal river]

EAGLE CAD

[raven hawk]

cool

[teal river]

I think they said KiCAD is what the rest of the team uses?

[open girder]

limor uses eagle, but some of the team uses kicad and/or eagle or both

[drifting wyvern]

I am very happy now that KiCAD has Eagle import.

[teal river]

Is KiCAD free?

[drifting wyvern]

Yeah open source

[teal river]

Noice

[ionic garnet]

@open girder do you guys have any adaboxes leftover? If so I'll buy a few subscriptions to give to coworkers. I know it's a subscription and that's ok.

[drifting wyvern]

Hey at least those imus are somewhat available. Apparently there are zero BMI150's anywhere and it's been that way for months

[open girder]

@ionic garnet you can sign up now and the next one will be adabox 020, shipping in a few months

for 019, we're out!

[ionic garnet]

yeah I will. I have my own subscription already. Wish I had thought to order more

[raven hawk]

I saw an ad today for PI kit on walmart for $180.00

[drifting wyvern]

Somebody wants macro pads for coworkers? 😁

[light stump]

So far I’ve only gotten the M4 to connect to sigrok, hit a roadblock on the RP2040 with cmake. Also I don’t think my sigrok changes have gotten merged so you still have to compile for yourself. Bleh…

[ionic garnet]

yes. I want them to take the edge computing and circuit python as a change agent seriously.

they're always thinking web, web, web and there's more to life than the web (though darned if I know what it is)!

[drifting wyvern]

I think the nano 33ble also has that

Now that you mention it

And it retails for $20

[open girder]

the part $ is now more than cost of the device

[teal river]

Bomb cost!

[drifting wyvern]

Yeah no kidding

[raven hawk]

I am going to be lazy and use simulink

[drifting wyvern]

I actually have a tool I built for work that depends on that imu in that board

[lilac tusk]

I’m trying to put a community order together for tqfp samd21 by Friday since they show a October 9th shipping date

On Twitter that is

Gotta order a lot to get a decent price to justify the tariffs and whatnot

[drifting wyvern]

That's a higher price than bno085 tbh...

(normally)

Everything is a temperature sensor, just of varying linearity and sensitivity

That one sounds right based on the Arduino servers iirc

[teal river]

The fact that Limor can remember all these part numbers is amazing

[raven hawk]

limor is hilarious

[teal river]

That too XD

[drifting wyvern]

The fact she knows imus (which I kind of know) in addition to everything else she knows (which I don't) is very impressive

Bno085/055 are the same chip different firmware

(basically)

And yeah it's more or less a samd21

[raven hawk]

I have no clue about chips

[teal river]

Chips no more

https://tenor.com/view/this-is-fine-fire-house-burning-okay-gif-5263684

[drifting wyvern]

Bno070/080/085 is when Bosch went to Hillcrest and said "our sensor fusion is not the best, maybe you can do better?"

Meanwhile, I'm here like "who cares about the mag, I'm never gonna use it anyway because it's too noisy"

🤣

[raven hawk]

I wish adadruits website would depricate items that are sold out to not show up on search rankings through ajax

[drifting wyvern]

Oh those modules are hugely expensive. Like, you can get a module with the bno085 (nominally a $15 part), and the module will be $200

[teal river]

I wish we could backorder

[raven hawk]

yay! @open girder

[open girder]

@raven hawk after a search, use the UI to change the results

@teal river yah, backorders would be tough to do right now

[drifting wyvern]

I want a 4 axis gyro. Tell me angular rates in space-time

[open girder]

can order via Digi-Key for example which allows backorders

(for adafruit stuff usually)

[drifting wyvern]

Invensense is pretty blobby

[teal river]

Does Adafruit get as much of my money if I order from DigiKey as if I order direct from Adafruit?

[open girder]

@teal river it works out all the same really, all good 🙂

[drifting wyvern]

Dual footprints...?

Thanks for that uplifting message pt😜

[viral sail]

Thanks @open girder and good night. 🌘

[maiden lily]

might just be with/without central ground pad

[teal river]

Bai! good show!

[ionic garnet]

bye bye

[drifting wyvern]

Key caps with the little pips on them please! (Maybe printable)

[teal river]

The world is doomed and we're all gonna be sitting around just playing with dirt

[ionic garnet]

i need to buy a new car and the inventory is a little scarce!

[drifting wyvern]

Have a good week!

[raven hawk]

yeah I ain't buyign a car anytime soon

[teal river]

Gosh, it's hitting so hard that the used car places around here that normally have 40+ cars only have like 5

[ionic garnet]

it's a company car so company is leasing

[teal river]

I plan to drive my current car until 2034

[drifting wyvern]

Imus are usually picky about how they're soldered, so I'd probably recommend going side by side before sacrificing the ground pad

[ionic garnet]

i don't have a current car. sold it during lockdown

[prime sentinel]

My car is only 13 years old, I'll just keep using it.

[teal river]

What'cha drivin'?

[ionic garnet]

i don't need brand new so i will find things. Want an Acura or Lexis type thing

[teal river]

Nothing wrong with used, just gotta be careful

[prime sentinel]

I'm driving a Lincoln Town Car I bought cheap with low mileage during the 2008 economic crash. I had negotiated mileage for the contract I was working at the time, and that extra $1400/month was a big help.

[ionic garnet]

yup. I'm thinking maybe not even used but leftover 2020 or early 2021 inventory.

[teal river]

Ohhh yeah, that should keep you going for a while if you're not driving a lot and give it the right maintenance :D

[prime sentinel]

Yeah, I like buying fleet duty cars. The previous one I got 500Mm out of, and sold it still running.

[teal river]

Most fleet cars are basically tanks, so even if they've already got high miles, they'll probably just keep running for a long time

[prime sentinel]

They also are generally easy to work on, parts are available and affordable, etc.

[teal river]

Mhmm, all the things that make them good fleet cars also make them good for you cars :D

I've got a 2014 Honda Civic, was new when I got it, and I'm keeping it for a loooong time

[ionic garnet]

i want something like an Acura TLX with Advanced package, SH-AWD and 360+ HP V6 but I'd settle for the 4 cylinder if I must. I can always look at Hondas to get a very similar vehicle. I'd consider used or fleet if they were still excellent. Want the Honda or Toyota lineage (Acura and Toyota) to make the vehicle affordable and reliable. Had amazing luck with Japanese almost-luxury cars

[teal river]

Honda is awesome. Some folks still have Civics and Accords from the 80s that have a couple million miles and are still going strong!

[ionic garnet]

I'll find out the budget and deal parameters next week when I'm at company offsite in California. But yeah, I really want another Honda. 3 of my last 4 cars were Acuras (1 MDX, 2 TLs - one with SH-AWD). Expensive to acquire, but compared to other executive vehicles like BMW, Audi, or Mercedes they are inexpensive to operate and very reliable.

Next week I have to go to my first business offsite since the pandemic. Not ready but it is what it is!

San Francisco here I come!

[teal river]

Woosh!

[grand tusk]

Open up that golden gate!

[raven hawk]

sf shrug

[teal river]

Too far

[raven hawk]

my grandpa buried there

[ionic garnet]

I guess I'm not really scared of the virus anymore. We have a few people coming from Europe and 1 from South America. I like SF because I started a great company based there in 1999. I lived in San Jose but spent a lot of time in the city. We'll actually be in the Santa Cruz mountains

[raven hawk]

most of my family from marin county

[ionic garnet]

direct flight so cuts down on some stress. I'm nervous to fly but as nervous as I expected. Marin is nice.

[teal river]

I shall never fly

[ionic garnet]

No?

[teal river]

Nope

[raven hawk]

but the housing shortage plus fires

[ionic garnet]

I have no choice. Hong Kong, China, Ukraine, Vietnam, Bolivia... all destinations as soon as possible

[teal river]

I can go anywhere without flying... just not fast

[ionic garnet]

Being CTO of global outsourcing company requires a bit of travel, as did my job at Jibo a few years ago

[raven hawk]

you can go by boat

[teal river]

Exactly

[ionic garnet]

I don't do well on cruise ships

[teal river]

Never been on a cruise ship, but I'm fine with motion

[ionic garnet]

i never got sick until on a cruise for more than a day

[prime sentinel]

The trick on cruise ships is to stay in the pool. Your brain is fine with motion if you're already floating.

[raven hawk]

hrm

[teal river]

I want to laugh, but that makes sense

[ionic garnet]

but whale watching or fishing or sailing. Haha about the pool. I'll try it though. Have to cruise at end of the year for my daughter's second take on her wedding. We had a small ceremony here but plan was to get married on a tropical island!

I am SO not ready for THAT

[prime sentinel]

Better than the Ice Hotel, I suppose

[teal river]

The one from that one James Bond movie?

[prime sentinel]

The seasonal one in (I think) Denmark, that's literally made of ice. Only accessible via dog sled or helicopter.

[teal river]

I think that might be the one they used in that movie....

Ah, no, the one they used was in Iceland

[prime sentinel]

I saw a show about the artists invited to build theme rooms. The one from Africa did a beautiful job, but admitted he was pretty much out of his element.

[teal river]

Yeah, Africa isn't known for its tundras, lol

[lilac tusk]

Parts of Wyoming are considered semi-arid tundra lol

Particularly the upper green river basin

[teal river]

Really? TIL

[ebon stratus]

Don’t know how to contact Ladyada so I’m just gonna put it here and see what happens.
Thank you
RE: working design of new neo pixel glasses.
Consider moving the empty space currently below the five rows of pixels, to the top. This way people will have more room to see out the glasses through the top rather than trying to look through the rows. Sliding the glasses down on your nose make it even easier to see above the pixels. You cannot do this if the open space is on the bottom as with your current design. Best Regards.

[river peak]

You can always use the [e-mail] e-mail and they'll send it to where it needs to go. LadyAda doesn't often check Discord so your message isn't likely to be seen here

I need to unplug this macropad. It keeps typing in boxes i don't mean to type in 😁

[clear matrix]

I hate leaving HID projects running. Especially if they light up or make noise. I'm so prone to fidget with it that if it's also doing HID things, I end up typing in random bits all the time. 😄

[teal river]

lol

Gotta have a fidget mode that turns off the HID part

[clear matrix]

OK that's a really brilliant idea.

Which will now be included in every HID thing I design.

DON'T CARE IF OTHERS DON'T FIDGET. YOU GET FIDGET MODE.

[teal river]

https://tenor.com/view/blushing-shucks-aww-gif-4120218

[opaque hearth]

Maybe on the rotary button...?

[clear matrix]

MacroPad rotary encoder switch sounds like a great fidget mode enable/disable button.

Yes that.

(Was already typing, but you typed faster.)

[opaque hearth]

haha

[clear matrix]

(Or shorter. Either way.)

[upper sandal]

like, long press it to enable/disable, otherwise you might click it accidentally too 😛

[opaque hearth]

@teal river coined it: Now known as Figit Mode

[clear matrix]

Eh, as long as it's not doing other things, I'm less likely to fidget with it. But yes, I agree. If I'm creating a fidget-mode, it should allow for fidgeting with the enable/disable button.

[teal river]

Hehe

[grand tusk]

A selection of animal noses are available in our gift shop.

[clear matrix]

Double click maybe.

I was thinking of making the keys require double click because I rotated the MacroPad so the legend on the display is now in groups of 4 in a 2x2 style. Versus the standard 3x4 legend layout.

So you click once, it highlights the matching legend item on the display, and second click sends HID.

(I mean it already highlights it, but that doesn't do you much good if it's the wrong thing.)

I'm really happy with how it looks. Simply trying to make sure it's usable for others.

[upper sandal]

I have a Keybow 2040 that is running a midi code, which just lights up keys when I fidget since I don't have a midi app running. The day I change it to do some hid macros, I'll have so many accidental inputs...

just muscle memory, you know

Question for the end Q&A: with the Qt Py RP2040, you have the bootsel button connected to GPIO for additional functionality and I see that you pass the QSPI_CS signal through a diode. If I wasn’t using bootsel as a user button in Circuitpython would the diode be necessary? I tend to think not but maybe I’m wrong?

So as a noob, I really appreciated this video. It finally makes sense to me.

[lilac tusk]

I actually read the research paper from Disney Innovation Labs about this two years ago

Or no, last year

[woven mirage]

I could use that pull-up resistor explanation for a student

[tribal iris]

I know i get it now

[woven mirage]

Another explanation said electromagnetism could influence a floating pin.

[waxen thistle]

@woven mirage Go ahead 🙂 It's there for everyone to use

If someone enjoys it or learns from it, it's a win all around.

[waxen thistle]

which paper is that?

[lilac tusk]

Let me find it

This is like a gloss over of it

Ah wait it does talk about the receiving/transmitting

[ivory kiln]

Q: about how long do u think the chip over price is gonna last?

[waxen thistle]

I've said it before -- when adafruit loses the top slot for #1 certified open source hardware, we all win.

With everyone else making open source hardware, it raises everyone to better places 🙂

[though it's pretty rad seeing Adafruit still in the top slot]

[nova totem]

And if anyone is thinking of it, getting your hardware certified is not hard. It took me maybe an hour, two most. If I had to do it again it would be way less

maybe the process could be automated. with circuitpython. 😉

[marsh tinsel]

I am LOVING the mistakes and mishaps theme. People always want to be perfect and photoshop their lives, but no one ever learns if they are perfect...

[river peak]

I got some PCBs in today! I didn't measure some footprints right and, uh. some holes were very wrong.

Learning means making mistakes.

[lilac tusk]

My mistake this week is realizing A. I didn’t have the GND pins on the SPI flash fully connected and the SD1/SD2 pins mixed up 😅

[waxen thistle]

I've failed far, far more times than i've succeeded.

[nova totem]

my first real PCB I had the wrong footprint and took me longer then i'll admit to realize what was wrong

[lilac tusk]

So I got RPI-RP2 but nooooo circuitpy when I tried to flash

Whoops

[marsh tinsel]

@nova totem Same. Basically all of my grad school.

Ohhhhhh

I need this

How much is this?

[river peak]

This product is going to... make waves

[lilac tusk]

I have like $200 of free cash flow business wise

Probably more than $200 😂

[waxen thistle]

It's.....not inexpensive. It's probably a nice value for what it provides. But it's not for the timid.

$1,454 for the 4-channel

$994 for the 2-channel

[lilac tusk]

Ah yeah, I need to sell checks math 100 PixelWing matrix at $39.95 a piece

[marsh tinsel]

@lilac tusk - I have reverse wired soooo many things. Blew up my first variable power converter

[lilac tusk]

Not impossible but 100 is a lot to make and sell for a small maker like me

[river peak]

100 is quite a lot

[lilac tusk]

My first run is 25

[waxen thistle]

I still argue if you can get an older Analog Discovery 1 used on the cheap (which is like 95% the same as the AD2), it's the best bang-for-the-buck.

[lilac tusk]

I’m hoping it sell well

[marsh tinsel]

My old prof refused to get rid of any his old analog equipment and now I understand why...

Sorry, the USB Digilent Limor is talking about.

Who knows, maybe I'll find one of these at the flea market and they won't know anything about it (or how to google it)..... 😉

[lilac tusk]

Maybe so!

[river peak]

Sometimes they just don't care, too

[waxen thistle]

So true -- nabbed a Wacom drawing tablet. They just didn't care to test it to charge more. And yes, it did work 🙂

Question for the show: when boards like the ESP32-S2 first come out and are “beta” and still not fully stable— is there a set period of time you have for watching a project for stability ? Hours? Days?

[lilac tusk]

[desert orbit]

❤️

[lilac tusk]

Okay I’ll scroll back

[river peak]

What do you mean by CP library?

[lilac tusk]

Yeah

Thanks Limor and PT! 🙂

[hot frigate]

So I can plug one into a Pi and use it outside of Labview.

[inner spade]

Thanks @open girder!

[lilac tusk]

A big inspiration for me

[hot frigate]

Thanks all!

[river peak]

Ah, I missed the first part of it

[urban gale]

thanks all! g'night

[hot frigate]

I have ditched labview in favor of CP, cause it's so much easier, and the future me doesn't need to learn labview, but can read simple Circuitpython code.

[river peak]

You wanted CircuitPython for the 3231, right?
https://github.com/adafruit/Adafruit_CircuitPython_DS3231

[hot frigate]

Nope, sorry, already using that (3231) project on my printer. The Diligent USB O-scope. Would love a CP library to use with it.

[desert orbit]

it runs linux and can probably handle running a python interpreter, so you could use blinka with it most likely, as long as a board definition got cooked up maybe?

[river peak]

I don't expect that will ever have CP dedicated to it. It's not going to be widespread. However, as @desert orbit mentions, you can probably finangle blinka onto it. And there might be someone out there that'll work the other way for connecting it to a pi and interpreting it with regular Python.

[desert orbit]

i use the mcp2221a all the time on my linux laptops with blinka. 🙂 ❤️

yeah i guess it'd depend what devices it presents to a USB host, if you're thinking about operating it via python/circuitpython using a usb-attached scenario

[hot frigate]

The Compact RIO rigs are the cheap ones, and are expensive. At $895 for it, seems like a cheap alternative for less critical stuff.

[desert orbit]

any device that has host drivers with VISA support are pretty easy to work with in normal python via PyVISA or VXI, actually

so not really circuitpython but it'd be python 🙂

[hot frigate]

I do a lot of it, regularly, with VISA and USB devices.. But, NI stuff is notoriously difficult to work with (for me, at least). Yes, Python is fine.

[desert orbit]

yeah, i learned that lesson a few weeks back during my first adventures trying to control some GPIB instruments (80's HP 3478A dmm and 70's HP 59303A HP-IB DAC) with a cheap NI GPIB-USB-HS from eBay...

spent many hours clicking around in LabView (which is neat? and i can see the appeal? but holy crap building a virtual instrument driver is a zillion clicks!) before I gave up and went right into Python 😂

[hot frigate]

YUP, exactly. I played with the Crayons and gave up.

[desert orbit]

so yea, in a host scenario normal python with PyVISA would probably be your best bet assuming it uses visa.

but it'd be so much more fun to run python on the device and see what kind of cool stuff can be done with direct access to those delicious DACs/ADCs. 😍

[hot frigate]

Python is king. But, labview and NI have their places (HUGE volumes of data, like planes, plane engines, etc...) But, in a small factory, it's much easier to implement things from the Adafruit library. If it breaks, just replace it.

[grim robin]

@nova totem @robust horizon @clear matrix : before I forget completely, here is a link for the code I used to run the kitchen clock : https://github.com/flavio-fernandes/kitchen_clock It also shows more info on the brackets I printed for it. Go circuit python!!!

I'd definitely recommend e-mailing this to [e-mail] about this. They don't often monitor Discord, so it might be a while before they see this. Pushing it over to them via e-mail will get it noticed a lot quicker and more reliably.

[waxen thistle]

Stream is live -- as for the audio, I have it on mute because Lars can't mindcontrol me if I can't hear him. I mean, because I'm on a conference call and still want to watch silently.

[waxen thistle]

Those wire strippers need a set of googly eyes. 👀

then again, googly eyes make everything better.

key lime pie plate. hmmm. pie 🥧

[robust horizon]

highly recommend to 3d print a keyswitch plate.

[waxen thistle]

no flicker, just a tiny bit of shake

[cinder wind]

RP2040 has 23 GPIO pins, so I think the biggest key matrix it could do would be 121 keys (11x11 matrix, so need 11 + 11 == 22 GPIO pins) and you'd still have one GPIO left over for all the neopixels per key

[lavish patrol]

No flicker at this end.

[shell mason]

those custom keycaps totally look awesome too

[robust horizon]

a little bit of sanding will take those right off

[lavish patrol]

I think Lars is training for the Olympics...

[waxen thistle]

[robust horizon]

I think you may need to jumper the neopixel back to the top

[waxen thistle]

+1 silicone wire -- that's some really nice stuff. Not good for breadboarding, but excellent for routing inside project enclosures -- super flexible.

[lavish patrol]

It's flicker-free here.

[cinder wind]

JP, seems like camera vibration on the stream I see (caused by HVAC?) that maybe shows up as flicker on your display?

[waxen thistle]

The stream itself on twitch is a bit laggy & stalls a bit for me -- but that could easily be on my end

[lavish patrol]

It stalled for me just now.

[woeful pond]

the stream on twitch stalled for me also.

[lavish patrol]

[viral sail]

@haughty quiver Is there a limit to the number of keys you can control with a RP2040?

[robust horizon]

When it comes to building layouts, you could create a layout from http://www.keyboard-layout-editor.com/ and then create an svg or dxf with http://builder.swillkb.com/ and then bring that into your modeling program to create the rest of the enclosure.

here's one very similar to John's layout

[robust horizon]

@viral sail as mentioned earlier, somewhat over 100

@viral sail no worries!

[clear matrix]

I want to document this but have no idea where it would make sense to put. I will remember you said that and ask you again when it comes up in the future and I've forgotten the actual numbers.

[cinder wind]

haha no problem. yeah it's exactly not intuitive. is there general learn guide about keyboards in CircuitPython or maybe in the docs about keypad?

[clear matrix]

Not really. The issue is that the info is RP2040-specific.

Which is why I'm not sure where it would fit.

Anyway, thanks for doing the math!

Dinner time here. 🙂

[cinder wind]

ahh I see. I thought you meant about matrix keebs in general

[clear matrix]

I see how it could be generalised. Hmm. Could go in the NeoKey Ortho Snap guide.

[cinder wind]

yeah maybe with a small list of "maximum number of keys for common boards"

[pearl shoal]

Hey @haughty quiver I've been having trouble with the Macropad (AdaBox CP version) when I use your MIDI code... after a while (5 minutes?) it stops sending events. Is this a known issue?

Sorry! I thought you're stream was over... this can wait 🙂

[clear matrix]

Unless you want to do the math on other boards, I think I'll stick with "For example, on the RP2040, you can have...." 😄

[haughty quiver]

@pearl shoal not an issue I’ve seen. I’ll test it later and see which CircuitPython version I’m running in case that is an issue

[pearl shoal]

@haughty quiver if you run your code and have this site open https://www.onlinemusictools.com/webmiditest/

Then rotate the wheel and you'll see the messages

Let it reset a few minutes and it will stop seeing the messages

[haughty quiver]

@pearl shoal i tried that test and it worked fine on that website after five minutes of rest.

[pearl shoal]

Hmm... I'm writing up an issue now per Dan... I'll send you a link

https://github.com/adafruit/circuitpython/issues/5101

[haughty quiver]

would you try it with a midi monitor program to help rule out possible browser web midi stuff?

[pearl shoal]

I started with the OBS-MIDI plugin, so I don't think it's web-usb - it had the same issue

But I'll test with anything you recommend

[haughty quiver]

oh hang on, I didn't realize you were talking about the Ableton code. I just tested the more basic Macropad MIDI code.

if you want, test it with this https://learn.adafruit.com/adafruit-macropad-rp2040/macropad-midi and I'll test the Ableton code

TBH -- the Ableton code is likely overkill for doing OBS switching so you may want to look at that simpler example code. Ableton has a two-way street with the controller, so the Macropad is both sending and receiving MIDI messages in that code.

[pearl shoal]

Ok, I can try with a simpler midi sender - any pointers would be helpful. I just installed MidiView and will let you know if that breaks too

Just stopped

Serial port sttill works

Still sending debug output

[haughty quiver]

I wonder if this is Windows 10 related then if both examples break. I've tested on Mac, iOS and MIDI host synth devices, but not Windows or Linux.

[pearl shoal]

If you could test it on Windows 10 I'd appreciate it - Dan says there are some USB drops he's seen on the RP2040? Perhaps MIDI doesn't recover like Serial/MSD?

[haughty quiver]

Will do. I just tested the Ableton code on that Web MIDI page and it continued working fine after 5 minute rest.

[pearl shoal]

Identical results w/MidiView
