dude once smote a fig tree because he was hungry and it wasn’t fig season. makes no goddamn sense, the guy was unstable. but i bet he was very entertaining.

i was *this close* to slacking my shopmates, “does anyone have a thing that can generate a 60-volt peak to peak square wave on their bench?” but yeah. felt like I should think harder about that question before plugging something i don’t grok into something else I don’t grok. Yet.

OK so this has me thinking now: clearly haptics happen in wearables. my apple watch taps me on the wrist. That linear actuator: is it operating at 3.3 volts? Higher? What’s the highest boosted voltage running on my wrist on any given day? https://twitter.com/josecastillo/status/1483539345009254412

You can usually order stuff one at a time; I just ordered 25 of another chip from here last month. I think either the supply chain craziness has everything turned upside down, or it’s a website glitch — and if it is, it’s a fun one :)

crunchy I imagine, but at this size they’re more like chocolate sprinkles than chocolate chips
(original)
haha wow, sketched out an idea this morning only to discover that while the chip isn’t quite unobtanium, it does have a minimum order quantity of EIGHTY THOUSAND. anyone want to go in on a group buy? 🤪

This is for the Open Book, where I’m trying to make it as easy as possible for folks to hand-solder. The last challenging parts on the board are the resistor arrays and the SOT-25 LDO — both of which I now realize I can get in SOIC variants.

Yep, this is with both pins toggling opposite each other (3V/0V, 0V/3V). It’s all good, this was just to satisfy my curiosity; I had a sense that vibration wasn’t in the cards for a watch add-on, this just helps confirm it.

Replying to @josecastillo
I looked at the data sheet beforehand, and it makes clear that at ±3V, the thing’s only going to move a couple of micrometers. Still, I wondered what that would feel like, and now I know! The sensation of a feather falling gently on another feather, haha. https://www.mouser.com/datasheet/2/400/0909h011v060-2636635.pdf

One down, one to go! I fed a 3V square wave into this piezoelectric vibration motor, and what happened was… not a heck of a lot. If anything the video exaggerates the effect; it feels akin to the flap of a butterfly’s wings or something. tho I admit I don’t find this surprising. https://twitter.com/josecastillo/status/1481801947988602890

Did a little scenic ride around Bed-Stuy this morn to test out a use case for the watch: handlebar thermometer! This is the same watch I’m using for the year-long battery test, btw; I don’t have it sitting on a shelf, this is how I’m simulating normal usage patterns: by using it.

Yea, I would go with Shortcuts. That’s my current method for weighing in; this shortcut lets me log my weight by voice to Siri every morning. But I sense there’s a way to tie a Pythonista output to a Shortcut input, if Pythonista could talk to the scale… https://www.icloud.com/shortcuts/7249c6782c0d47a9bf9fd279584a7e64

after posting about water resistance, @getur asked me if the watch floats. I just had to.

Your question made me say “huh, I wonder!” out loud; it turns out the answer is no, it does not float.

A few years back I was playing with a Bluetooth thermal printer via Pythonista. Wild, even without a Swift app, you can write code on your phone to interface with Bluetooth devices. I bet you could combine that with Shortcuts to get data into Health. 🤔 http://omz-software.com/pythonista/

Anything stashed in the BACKUP registers, too! It should have saved your 12/24 hour preference and custom LED color, if you set one. (currently doesn’t save your world time locations, but that’s in the works)

I mean, I hope not? I’d like to just buy something that works, but it seems like literally none of them are designed to help me watch my weight. They’re all designed to help _them_ watch my weight.

Off top of head, the button idea should work (i.e. if the RTC is running, tie an RTC interrupt to the Alarm button that resets the board). It will definitely require a bootloader change. Thank you for catching this failure mode now! I will work on it.
(original)
Replying to @tahnok
Oof wow, that’s an interesting one. I’ve dropped it hard and had it reset, but the time and most settings are persistent, so it just kept ticking. Dropping it and having it enter bootloader mode is more problematic. I will need to think about this.

Question: a Bluetooth scale that syncs to Apple Health, WITHOUT having to sign up for an account with the device manufacturer. Does something like this exist? This SO answer suggests one (but they require an account now); beyond that, it’s all hacky hacks. https://hardwarerecs.stackexchange.com/questions/10472/cloud-free-smart-bathroom-scales

Last night I threw a Sensor Watch into a washing machine to test its water resistance after the board swap. It went well, but just to be sure, I also took a shower with it this morning. To be clear I think it’s ridiculous to wear a watch in the shower, but I’ll do it FOR SCIENCE! https://twitter.com/josecastillo/status/1482912801240887296

The clock is weird because it’s showing the time in Canberra; I’ve had the Deep Space Network on my mind. also I’m not surprised by this; the mod involves swapping a circuit board, but it’s the same enclosure, same gaskets; there’s no reason it wouldn’t be as WR as a stock F-91W.
(original)
Replying to @josecastillo
Also thrown into the wash: a Sensor Watch. I realize I’ve been coasting on the F-91W’s reputation for water resistance, but I can’t not put it to the test. It survived a quick wash in hot water, an extra rinse, and the spin cycle! Gratuitous campaign link: https://www.crowdsupply.com/oddly-specific-objects/sensor-watch

lol, emptied my backpack to throw it in the washing machine, and while giving it a shake, these fell out. One of the problems with making tiny things: I’m losing track of them all the time.

Maybe I’m doing something similar in the opposite direction here, imagining cars as these feral beasts that roam the streets; it doesn’t even matter who’s behind the wheel.

Replying to @rohansingh
i remember this line a from a few years ago talking about how when driving a car people personify the object. Like, after a collision, you’d likely say “he hit me” and not “he hit my car” (or “his car hit my car”). Not sure if relevant but it just came to mind when you said that.

to be fair, he did pass me again about a mile later, but then I passed him shortly after, making a right turn while he was stopped… at a red light.

why are cars so aggro when most of them are just driving to a red light? Dude honks at me. Runs me out of my lane. Not even nine seconds later I pass him when he’s stopped at a red light.

I’m really curious (but don’t yet know) if all this data is necessary to calculate RA and declination for our purposes. like, I think this library could give me Jupiter’s location in the year 3000. But if I just want data for the next, say, 5 years, can I get away with less math?
