This is my sense of power consumption with the new firmware. In theory I’d expect one year battery life with sleep mode disabled, though you’d likely stretch that a fair bit longer if you took it off at night; this assumes wake mode at on-wrist temperature, which eats more power.

It was such a blast chatting with @AlpenglowInd on the Solder Sesh last week! One regret: I misstated the timeline by one year in this clip. @GregDavill’s ARM Watch was December 2020, I started Sensor Watch January 2021 and launched on @crowd_supply 2022. https://youtu.be/txBj8-7Heg4 https://twitter.com/AlpenglowInd/status/1584589191400525825

somehow in the midst of everything else I have going on, I managed to get some new business cards made. If you see me at Supercon next weekend… ask me for a business card :)

Battery test, day 350: 2.73 volts. Old firmware seems well on track to lasting the full year! New firmware seems to be fluctuating around 3.08~3.09 volts, so I’m marking it 3.085 volts at day 245; since it’s 105 days behind the first test, it’ll hit the one-year mark in 4 months.

the desktop edition is also very much free, so you can try it out and see if it works for your purpose: https://www.manager.io

Manager isn’t open source, tho I do find it useful! It has inventory features like the ability to track purchase orders and production runs, but it’s not specifically aimed at electronics manufacturing; it’s more designed for general accounting for a production-oriented business.

I turned 30 some years ago now, and while I’m not sure my advice at this point is good, I’ll share a thing I wish I’d grokked at 29: there’s a time to exchange time for money, and a time to exchange money for time. the moment may come; the trick is knowing when to make the switch

Right yea I’m imagining drawing a wire and having it follow my pencil, with the ratsnest line following until I’m connected — then drawing a neighboring trace close by and having it hug the first trace in accordance with my track spacing / design rules. It makes sense in my head!

Honest question: I want a KiCad plugin that lets me draw traces by hand with a stylus or an Apple Pencil, like I’m old school with a Sharpie and a vat of etchant. Does this exist? I have an oddly round board stuck in my head, and I really want to route it freehand. https://twitter.com/GregDavill/status/1583578821651238912

I’m not going to get all gatekeepy and say “real artists ship”. If shipping product is part of your practice, great; if it’s not, that’s valid too. I will however say this: shipping feels real good.

Updates are one an hour; the color e-paper takes a bit to refresh, so that’s about the quickest I’d want to update it from a UX perspective. This is using a 1500 mAh battery (and the Newt is on 850 mAh); not really scientific, but batteries that feel right-sized for the gadgets.

Low power gadget watch! I recharged both @darianbjohnson’s Newt and @solderedcom’s Inkplate 6COLOR on October 1; twenty days in they’re both still, y’know, doing their thing. Also: two @crowd_supply projects on our fridge!

I heard this on @TPRSource last night and sorta had to pick my jaw up off the floor. This is Republican Mark Dorazio, candidate for Texas House of Reps, describing his uttterly unhinged world view as something to aspire to: “When you look at life, life can be summed up in money.”

There’s a big constraint and a big question in my head before I make my own watch. Constraint: I’d want 2+ year battery life. Question: given the constraint, would it have a dot matrix like the Sharp display, or a custom segment LCD? There are engineering tradeoffs on both sides.

LIS2DW is at the top of my list, not least because I have over 100 of the sensors just sitting here on a reel. It’s definitely a next year project though; there’s 700 temperature sensor boards and 980 Sensor Watch boards still to ship by the end of this year.

A video of the TOTP watch face in action! And as for the rate meter face, thanks to @a2’s brilliant work on the Sensor Watch emulator, you can play with that watch face INSIDE the blog post! https://blog.singleton.io/posts/2022-10-17-otp-on-wrist/ https://twitter.com/dps/status/1582238330262994944

This great blog post by @dps describes putting TOTP keys inside a classic Casio wristwatch! It also includes a whole section on how David wrote his own watch face, a cadence tracker, for Sensor Watch. The verdict? “Both easier and more fun than I expected.”https://blog.singleton.io/posts/2022-10-17-otp-on-wrist/

Thought a lot about it! In fact I’ve had a test design (with the SAM L21) running on a coin cell since… March? April? I’d definitely need more experience w/ industrial design to come up with a case… but it’s something I hope to learn on while working on the Open Book next year.

Twenty eight rubber bands binding twenty eight groups of ten packed sensor boards. The next shipment to Mouser is 50% complete! Next stop: Sensor Watch main boards.

Replying to @dcelectr
They are suuuuper flexy! Also I think I have a hunch why @oshpark’s boards are thicker: their substrate is thick enough to plug into typical flex connectors without a stiffener layer. Which makes it easier to design for, since stiffener would be difficult to do on a shared panel.
(original)
Replying to @josecastillo
I love it when the numbers add up. Printed 280 labels, stuck them on 280 antistatic bags and depaneled 280 sensor boards; now after having packed 277, three of each remain. Everything is accounted for.

Replying to @bateskecom
No bet, no bet! I know exactly the board you’re referring to and it was such a clever use of flex :)
(original)
Replying to @josecastillo
The leftovers. Technically that strip of darker brown across the bottom of each board is a stiffener that adds another 0.1 mm of thickness; either way, so tender it falls right off the bone. https://www.pcbway.com/flexible.aspx

Bet you’ve never depaneled boards like this before! That’s a PCB on a polyimide base just one tenth of a millimeter thin.

This is a great call to action for a spear phishing attack.

Montage: the next 300 sensor boards! @MakeAugusta delivered enough Sensor Watch main boards to fulfill all @crowd_supply backers, but it’s up to me to lovingly place each component on the tiny temperature sensor you receive. (These most excellent flex PCBs are by @PCBWayOfficial)
