A whole other kind of atomic clock!

I’m being a lil tricky; this only works for like 20 seconds. the LCD peripheral’s super low current draw means I can coast by on residual charge in the filtering caps before the gadget dies. I plan to put a tiny solar cell on here, but thought this was fun when I saw it :)

I mean not necessarily! I’m not saying dialup days were better, just that our expectations today are biased toward something that only a commercial operation can deliver — and the tradeoffs required for that lead to a different internet than we’d have if we made different choices

yes mastodon has its issues, I can’t upload photos sometimes, and it’s not the most reliable. on the other hand: “going online” once involved trying again after a busy signal. We’ve made tradeoffs to get to the world we live in now; this is a chance to ask if they were worth it.

I LOVED THAT SERIES SO MUCH! What a show. Immediately after I was hungry for more from him so I watched Annihilation, highly recommend if you haven’t seen it.

I put Sensor Watch developers through something similar to this: to fit location in 32 bits, we store latitude and longitude as a whole number of centidegrees.

ah this isn’t After Dark, it’s just black solder mask and white silkscreen… the beige area is plain FR4 where I’ve stripped away the soldermask. (for this prototype, black will be purple, but I’ll do it with matte black mask if this first test works)

the OSH Park preview doesn’t show it all, but I know how the layers work; this is gonna be dope.

trying to send out a prototype design tonight, and hated the placement of my debug test points: front and center, at the top of the gadget. Only place they fit. Luckily I was able to art my way into a solution.

Here’s that A163W. It’s a handsome looking watch! https://twitter.com/cybertool/status/1586828274046468097

Two more Casio watches confirmed working with the Sensor Watch board swap: @cybertool found it working with the stainless steel A163W, and @shogookamoto breathed new life into a vintage W-31 (which it seems Casio started manufacturing in 1984?!) https://twitter.com/shogookamoto/status/1586726204694228993

I recall that there was low level support added for passing in partial refresh commands in the initializer, but I’m not sure if any of the drivers implemented this. I did a grayscale mode in CircuitPython for the 4.2" displays way back when, but never tackled partial refresh.

I need to update that page; backers are all fulfilled, and we’re hoping to get the preorders out by Christmas.

new profile pic and all that. The old one is like a year old, and I don’t nearly have time to straighten my hair these days. Point is, if you plan to run into me at Hackaday Supercon next weekend, this is me now.

I remember the first time I saw the Sensor Watch work. It was such a thrill to see this humble object do so many things. I so deeply wanted to share that with other folks, and no matter how many times I see this moment, it always fills me with joy. https://mobile.twitter.com/MohitBhoite/status/1586507767572930560

there’s one last very fun bit of functionality. The “free” pin next to TX was unused; in my design, it breaks out the L21’s emergency backup power pin. Adding a coin cell here should let the microcontroller’s real-time clock keep ticking, even when the main battery is dead :)
(original)
Replying to @josecastillo
The differences:
• A3 is PA06 instead of PA04. PA06 wasn’t broken out on the SAM D21 Feather, but on the L22 it’s an opamp pin, so we want it.
• AREF is PA04 instead of PA03, again, because PA04 is an opamp pin and PA03 isn’t. With this… https://mastodon.social/@joeycastillo/109250180107512798(original)
Replying to @josecastillo
admittedly I had a big assist from Adafruit here; the L21 Feather is _very_ similar to the Feather M0 Basic. The pinout is mostly the same, which should keep things simple; all the differences have to do with three analog pins. CC-BY-SA design files here: https://github.com/joeycastillo/feather_low_energy

I would recommend it highly! Super lightweight, intuitive and powerful; heats up fast and works with a ton of USB-C power supplies I have sitting around the house. Strong buy.

not a big brag, just a small point of pride: I designed all of the boards plugged into this featherwing quadrupler. What can I say? Sometimes my requirements are Oddly Specific.

There was some gnashing of teeth over a poorly soldered joint on the USB port, but a couple of once overs with the new Pinecil got me back in business. That green LED means we have bootloader!

Stoked to assemble one of these tonight! 🐘MicrochipMakes@twitiverse.com SAM L21 in an 🐘adafruit@mastodon.cloud FeatherWing form factor. Shiny purple boards by 🐘oshpark@twitiverse.com; in my head I’m calling this Feather Low Energy, for the L21’s low power powers :)

You should be able to search for @joeycastillo@mastodon.social on any Mastodon server; the instances are all connected (with some limited exceptions), so even if we’re on different servers, you can follow me and I can follow you.

If anyone is interested in how to mirror from Mastodon to Twitter, I’m using this tool. Pretty simple: you log in with both services, flip a switch and the posts flow. (my experience so far is that there’s a slight lag before it shows up on birdsite) https://crossposter.masto.donte.com.br
(original)
I’ll be honest. I neglected to prepare for this moment because I really didn’t think he’d do it. Now it seems he did, so here’s the plan: I’m posting this from Mastodon. Posts will mirror to Twitter for a time; then at some point, they won’t. Handle in username; follow me there.
(original)
a little conversational tic I’ve adopted: when thanking someone at like a post office or a coffee shop, instead of saying “I appreciate it” I say “I appreciate you.” it’s a small change. but it reminds me to center the human in an interaction, rather than the thing.

If anyone working @Apple is reading this, this is a major regression in MacOS Ventura that will break a lot of people’s products (including my Sensor Watch). A change to Finder has broken the common workflow of dragging UF2 firmware files to mass storage devices. Plz to escalate. https://twitter.com/aallan/status/1585371496046014464

I think the thing is, since they’re using their own counterfeit chip for the quartz movement, as well as their own counterfeit board, and their own counterfeit LCD, there’s no need to abide by the pin assignments on the original; they can just go with whatever’s easiest to route.
(original)
Replying to @AlpenglowInd and @clovis_cormoran
FWIW I knew yours was legit when the LCD worked. While the counterfeiters are pretty thorough, none that I’ve seen have cared enough to clone the LCD segment mapping; this means the fakes tend to display gibberish when the Sensor Watch board is swapped in. https://twitter.com/josecastillo/status/1425884054310768649

Little bit of the same gadget if it keeps selling, little bit of a new gadget if I can get the chips. also I’ve had a little bit of interest from folks who want to buy the displays standalone.

I keep coming back to this idea constantly. In college (photojournalism) all of us just had our photo blogs, and we kept up with each others’ work in Google Reader. Idyllic. And it worked seamlessly, for so many non-technical folks! Still I don’t know how to get there from here.

Come to think of it, that’s a great idea for a learn guide: LCD FeatherWing Christmas light controller :)
(original)
today I took a leap of faith and submitted a purchase order for more LCDs; then this evening I received a purchase order for 100 more LCD FeatherWings. It’s one thing for a gadget to work; another for a product to work. Here in Q4, I’m daring to hope that the business might work.
