Huh, I guess it makes sense: he was at Harvard at the same time as Zuck, class of ‘04; Facebook launched four months before he would have graduated. Wild.

wait. what? is it seriously possible Pete Buttigieg was the 287th person on Facebook? (for context: this security researcher is looking through the leak that exposed 533 million Facebook users’ phone numbers, and these are the lowest sequential user ID’s; Mark Zuckerberg is #4) https://twitter.com/mikko/status/1378732263266004994

One output is for the microcontroller, where I can use sleep modes to save power; the other output is for any gadgets I can’t put completely to sleep, like sensors or Neopixels or in some cases a display, if the driver sips more current than I’d like.

Lately I’m extremely partial to the AP7332 voltage regulator. Costs a bit more than my usual go-to LDO, the AP2112K, but for low power projects I appreciate having two outputs that I can control independently. https://www.digikey.com/en/products/detail/diodes-incorporated/AP7332-3333W6-7/2594046

I was sitting here Wednesday night agonizing over what typeface to choose; then I thought “joey, be real: you’re going to reprint all these labels anyway. Pick a font and move on with your life.” Comic Sans was the only logical choice.

workbench glow-up! it was a year ago that I fled the city (and the shop); the bench has been feeling lonely ever since. added louvered panels and bins to organize my parts; also remade my project tracker on a new magnetic whiteboard. Working from the workshop from here on out :)

Meant to share this yesterday but wow is this thread essential reading, especially for parents and soon-to-be parents. The cruxy bit: “Kids whose identities are unsupported have horrible outcomes. Kids whose identities are affirmed have outcomes pretty similar to cisgender kids.” https://twitter.com/JesseThorn/status/1377287133921116160

ok so it seems it made sense at first: 1a was healthcare personnel; 1b was essential workers / 75+; 1c was 65+ / people with comorbidities. by the original definition I should be in phase 2. tho for clarity we could have just called them phases 1, 2, 3 & 4 https://www.cdc.gov/coronavirus/2019-ncov/vaccines/recommendations.html
(original)
I’m not exactly complaining or anything, but is it weird to anyone else that the vaccine is open to everyone born since 1991, and we’re still in phase 1b? like, who exactly is in phase 2? even airline boarding priority makes more sense than this.

Totally! For my part, I keep a handful of SAMD21’s and SAMD51’s on hand in various packages for when inspiration strikes. It’s how I managed to iterate on the PyCorder despite this whole situation…
(original)
just made a leap of faith: ordered 100 chips for the watch. I still don’t have my USB problems solved, but watching Desk of Ladyada, her comments on the chip shortage convinced me to press the button. I’d hate to figure out the software only to discover I can’t ship the hardware.

Like, yesterday I read a deep dive from the Financial Times on the bank effect, and shallow-water hydrodynamics as it relates to trends in container ship hull design, and the whole time I kept thinking “So what you’re trying to tell me is, big boat stuck?” https://www.ft.com/content/171c92ec-0a44-4dc5-acab-81ee2620d3c1
(original)
I think the reason I find this big boat story so fun is that it’s so dang comprehensible. There are no shadowy hackers or vast conspiracies. You can explain it to a 5-year-old. What’s the problem? “Stuck big boat.” How stuck is it? “Boat stuck big.” Any updates? “Big boat stuck.”

my first instinct was to get it stuck in Brooklyn’s Gowanus Canal, but it didn’t make it very far
(original)
this fun project from @en_dash lets you get the big boat stuck anywhere, and it’s actually wild to see the thing at scale. like, here it is parked in the Central Park reservoir, where it looks comparable in size to the Metropolitan Museum of Art. https://evergiven-everywhere.glitch.me

oh also! Note that with regard to the microSD slot, there was a misprint on some of the printed BOMs that were sent out. The Kitspace BOM and the spreadsheet in the repo are fine though. The correct part is Würth Elektronik part 693071010811: https://www.digikey.com/en/products/detail/693071010811/732-3819-1-ND/3124603

Should be fine! The T in this case just means it comes on tape I(nstead of a tray), but if you’re just ordering individual parts for building by hand, that doesn’t make a difference. Let me know if you have any other questions about the build!
(original)
Replying to @florianherrengt
I need to get on that. The demo software is in Arduino and works quite well, but I had started coding some Python-based software for book reading (so folks can see and change the code on their device). I feel a tension between demoing what is, and building what I hope will be.

Replying to @florianherrengt and @the_prepared
Assembling this board, not long; maybe half an hour all told. But figuring out how to design this board? Gosh, a long time; I’ve been hacking on the Open Book in some form or another since 2019.

Replying to @josecastillo
(also to be clear: the “it” in this tweet refers to my design, not the Pi Pico. The RP2040 seems capable of some wild stuff, especially its PIO peripheral. Here I’ve chosen to use it in a design that optimizes for a specific use case; my limitations will not be the same as yours)

Replying to @l0wagner
ooh is there a battery! It’s not mounted in the photos I posted, but I’m pretty stoked about this part. It’s super slim, high capacity and inexpensive on Aliexpress. I arranged the components specifically to be able to fit it at the bottom where it’ll feel balanced in the hand.
(original)
Replying to @josecastillo
Still some work to be done here. I want to explore using larger passive components, to make it easier for beginners to build. And there are still a few tricky parts that I’d like to refactor to make simpler. Anyway. That’s where my head is at with the Open Book right now. /thread

Replying to @josecastillo
…but as the saying goes, “less is more when more is no good”. In cutting down to just 42 parts, it’s both easier to hand-assemble and cheaper to manufacture. The lower the cost, the more accessible it is. And even then, some of these parts are optional depending on the use case.
(original)
Replying to @josecastillo
The Pico version is the one I assembled today, and it’s kind of bonkers: all the parts circled in yellow on the original Open Book (on the left) get replaced by one castellated module with a wide, friendly pitch. It does less, to be sure; there’s no DAC or Feather compatibility…
(original)
Replying to @josecastillo
the original Open Book used a SAM D51, a chip I adore working with. but in an effort to lower BOM cost and simplify assembly, I’m playing with 2 new variants: a full-featured Feather-compatible Open Book ESP32-S2, and a low-cost Open Book Abridged Edition with Raspberry Pi Pico.
(original)
today’s main task is to move back into the workshop — 👋 @the_prepared — but while packing, I figured I’d assemble one last object at home: the Open Book Abridged Edition. It passed its smoke test, and got me thinking I should share a short State of the Book update. (thread; 1/?)
(original)
Replying to @AllenHMowers
Oh wow, honestly, just here on Twitter is probably the best place! I will also probably restock the E-Book FeatherWing before I figure out the other thing, so the waitlist for that one would also ping you when I start to get things together.
(original)
Replying to @AllenHMowers
Thanks for the kind words! I’m actually working on an update I can share today; I’m iterating on a new version of the book based on feedback from folks who have assembled it. The goal is to make it a simpler build, though it may be a few weeks before I’m ready to get boards made.

I’m not currently planning to try to make these at any kind of scale — the watch and the book are the two projects I think I can reasonably put into the world this year — but I’ve published all of the information you would need to build your own here: https://github.com/joeycastillo/pycorder

oh also! The 3D printed case (still a work in progress) was extremely inspired by @stephentherobot’s Open Book build. It had never occurred to me to use the circuit board itself as the front of the device; such a cool idea! https://twitter.com/stephentherobot/status/1366487259915182090
