i sense something different about this watch....... 🤔 #casio #sensorwatch (big big thx to @joeycastillo !!)

@webmontagkiel bis zum 18.9. sollte ich endlich meine #SensorWatch fertig haben, falls es ein Thema für den Webmontag ist.

We're excited to find out how to make the most of your microcontroller from @joeycastillo creator of the #SensorWatch, now at @crowdsupply #teardown23 https://www.crowdsupply.com/teardown/portland-2023/long-talk/making-the-most-of-your-microcontroller #portland #pdx #openhardware

Okay das ist schon ziemlich cool: Sensor Watch https://www.sensorwatch.net/
>A board swap for the classic Casio F-91W wristwatch

@darth ever heard of #sensorwatch

The #SensorWatch is a really nice upgrade to any #Casio F-91W.

Also, I have a cold. Read all about it.

A pretty neat thing #SensorWatch can do is to generate TOTP-codes for two-factor auth.

Yes, I have an app for that on my phone, and that's more convenient (especially with copy-paste between phone and computer), but it could be useful for some important auth that might be needed if I ever lose my phone.

The secrets need to be compiled into the firmware, then the watch need to be disassembled to program it, but it's still neat. 😄

Take it apart, swap the board, and put it back together. Done!

A bit fiddly, but doable.

It's now happily showing the temperature (the reason for it being called Sensor Watch is that you can plug small sensor boards into it), and whatever other features are in the firmware you program it with.

Only downside it that you need to take it apart to plug in USB-cable to flash a new firmware.

#casio #SensorWatch

I have been watching various watch board replacement projects such as GoodWatch and Pluto Watch for years. I have also thought about making my own.

I would have liked to be able to fit an nRF52840 and an LCD-driver and do Bluetooth LE and RFID. But I never got very far.

Then the #SensorWatch showed up on CrowdSupply a year ago. I did not order right away, but now they are in stock and shipping. I ordered a week ago and got it today.

Not exactly the functions I wanted, but still pretty neat.

I’m sick with cough and runny nose, but FedEx just dropped off an oddly specific object …

I think by now I am well over budget in the Fun Electronic Things-department.

@joeycastillo just got my #sensorwatch, now I only have to remember where the watch is! 😎

Can't think of a better way to spend a Sunday morning than #hacking my #Casio F-91W watch and replacing its control board with a #SensorWatch board (https://www.crowdsupply.com/oddly-specific-objects/sensor-watch). 😆
I really do love that someone took the time to design a board compatible with a watch that's been around for 33 years (!!) and that it's open source. That allowed me to compile a custom set of watch faces for the firmware on my board.

So far I have gotten this working with one last piece that is missing. The #sensorwatch faces appear to reset their state when they go into the background. I have not yet found a place to easily store my 8-byte counter value in a persistent manner. I have two options to explore though: the RTC's backup registers and the EEPROM lfs filesystem.

Converted my Casio A159WGE successfully to a sensor watch thanks for making such a great project @joeycastillo very easy to do the conversion. Lots of potential for some fun interfaces when I’ve got a bit more time.

The watch has an ARM chip in it, and could run basically anything an ARM SOC can run. But input/output would be a challenge since the watch is limited basically to three buttons and a limited segment display. The devs provided 'movement' as a default app and framework for handling I/O and giving us a way to quickly develop apps. #sensorwatch #oddlyspecific

First challenge, how does the #sensorwatch firmware work? I am aware that there is a simulator available that can run the watch firmware in the browser, but I have no idea how to build or use it https://joeycastillo.sdf.org/sensorwatch-rc2/watch.html

Dang, sketches didn't show up!

#SensorWatch sketches to maybe turn into a pocket watch with a spring loaded cover and/or vertical actuators for the 3 Casio buttons :)

Second iteration of my #SensorWatch case

With some sketches / beginnings of ideas on the final form

The nerds over at the #SensorWatch discord are working on magic that takes the #F91W towards #grandseiko quartz accuracy. Most impressive!
