as seen on @adafruit Show & Tell: PyCorder air quality monitor! This graph is showing a spike in particulate matter after my roommate sautéed some veggies (an exhaust fan and HEPA filter are clearing the air). Did you know cooking contributes hugely to indoor air pollution? Neat!

(the app still exists, and I still use it, but the GPS tagging is less useful now that we spend almost all of our time at home 🙃)
(original)
Replying to @gennyble
I use an app called Life Cycle which (was) great for categorizing activities with GPS. Tell it your home and office and it’ll track work/life balance; add an Apple Watch to track sleep hours; tell it about favorite haunts and it’ll quantify where you spend time. I find it useful!

Replying to @gennyble
I’ve been into this for years! Used to manually track activities, but I’ve found passive monitoring (fitness trackers, on-device GPS logs) to be most useful. Answers questions like “how well do I sleep / how much am I exercising / is this correlated with less time spent at bars?”

“I am terrible!” Big Boat told the teeny yellow construction trucks.
“No, you are nice!” they told her.
“I am the Biggest Worst Boat that ever lived,” she told the canal workers.
“We like you, Big Boat,” they said. But Big Boat couldn’t hear them. https://defector.com/big-boat-stuck-a-story/

when he said this, fewer than 1,000 people had died of COVID in the US. I wonder if he imagined the body count would reach half a million. I wonder how much money he made in the interim. I wonder if he’s OK with that tradeoff today.
actually, I don’t wonder about that last one. https://twitter.com/josecastillo/status/1242900989545414658

I mean, you’re right: intent should be respected. but in today’s case, many hundreds of Rails developers intended for their work to be shared permissively, but the creators of one XML file intended that file to be shared restrictively. It poisoned the well. that’s my frustration.

Replying to @davidskeck
and the way these conversations go down, it seems like you almost need to consult a lawyer before even glancing at GPL code, which fuels some of my frustration. I just want to make things. https://github.com/zRedShift/mimemagic/issues/4

Replying to @davidskeck
it wasnt my intent to offend people of good faith who believe; my frustration is, I know which things I want to copyleft and I know which things I want to share outright, yet I live in fear of fanatics showing up in a repo telling me my whole life has to conform to their license.
(original)
Replying to @abetusk
Not a RMS thing (though, WTF), and I use BY-SA myself for hardware and documentation. But when it comes to software, it seems like a common occurrence for the incidental use of a config file or a couple of lines of code to bring out the GPL police to break lots of people’s work.
(original)
Replying to @SoopTikoon
Definitely MIT. if someone wants to take code I wrote, modify it & bake it into a product, I’m fine with that. My intent is to share, not to create an obligation. (yes the copyright notice requirement is technically an obligation, but one that’s easy to comply with in good faith)

Please don’t use GPL code in your projects, sure. But also, please don’t release GPL code into the world. Pick a license that lets people do and make and build things, instead of forcing them to deal with pedants who care more about purity than the people using the code.

Heya Greg, I’m curious, did you ever order this board? Wondering what fab house you would use for a board with a fine-pitch BGA like this and if there are any special processes involved. (context: I have a SAML22N idea in my head, but have never worked with this kind of package.)

Thanks Scott! This is probably the next step for me, at the very least seeing how far I can get peeking at the bus in software (tho videos of the Beagle at work look shiny). Super helpful guidance, I appreciate it!

I’m still guessing at the underlying cause though; thought it might be because the main clock (GCLK0) is still only running at 4 MHz, but it’s confusing to set it up because it’s all in Atmel START config files. Gonna take another look tonight when I’m done with day job stuff :)
(original)
Replying to @tannewt
This is helpful; led me to the point I’m at now (I have a 500Hz PWM validating my 48 MHz clock on GCLK2, which I’m feeding the USB peripheral). Running the MSC example, there’s a blip in my logs where my Mac “sees” a device, but it goes straight from ’not mounted’ to ‘suspended’.

Replying to @josecastillo
I know I could ask for help here; truth is, I hate wasting people’s time by not at least trying to figure it out myself first. often I feel I dive deep in order to hone the question I want to ask, only to find the answer was closer at hand than I thought. anyway. to be continued!
(original)
SAML22 TinyUSB update: closer. I think Ladyada was right at Show & Tell the other week: it should “just work” if I can get the project set up correctly. I think the piece I’m missing is getting the chip to run at 48MHz, instead of just having a 48MHz clock for the USB peripheral.

now that might be interesting… could even make the whole EPD driving circuit its own castellated module, like Adafruit’s e-ink friend but sized to fit the book. HMM!

I will say I’m seriously considering moving to 1206 parts for the Pi Pico version of the Open Book, because I recognize it’s definitely more accessible. Alas, the 24-pin, 0.5mm pitch flex connector is the one “expert mode” part I can’t quite refactor out of the design 😖

Replying to @MakeAugusta
Agree with several comments here: fine tweezers, SOIC chips and 0805’s were a sweet spot for me in the beginning. I’d also put a huge emphasis on magnification, even if it’s just strong reading glasses from the drugstore. It was like night and day when I added that to my process.

BTW, mega thanks to @theavalkyrie for her excellent write-up on the SAMD21 clock system! This is the second time I’ve referenced it while working through a challenge; I love the way she explains complex systems in a way that’s both accessible and in-depth. https://blog.thea.codes/understanding-the-sam-d21-clocks/

reasonable TinyUSB progress tonight. fixed my failure to clock the USB device properly; now my laptop can sorta see it, and the blinky light is blinking promising blinks. haven’t yet had it mount as a USB drive but it feels close, like I just need one more night of hacking on it.

It’s a DSO Nano. I will say it definitely has its limitations, but since I don’t (yet!) own a full-featured scope, it’s been a lifesaver. https://www.adafruit.com/product/468

Replying to @tomfleet and @wizardOfRobots
yep. Tho to be clear, it wasn’t melted into place or anything; just a dried and hardened piece of solder that had wandered its way in. came out with a pair of tweezers, no fuss.

Replying to @tablatronix
I did not do a great of a job soldering this connector the other day; had a couple of bridges and reworked it a bit, probably used too much flux. I’m beginning to see the value of investing in an ultrasonic cleaner.

Figured it out! Not as interesting as it initially seemed. Turns out it was a really clever little fleck of solder that wanted to see me squirm: https://twitter.com/josecastillo/status/1373397798821969921
