The heart rate is calculated manually by counting 20 heartbeats and using the timer. Here are a couple (and I recall one other project but I can't remember the name of it right now) open source alternatives for those who aren't trying to fw a proprietary app/closed source system. https://github.com/joeycastillo/Sensor-Watch https://github.com/PegorK/F91_Kepler

There are details on the sensor part here: https://www.sensorwatch.net/docs/sensorboards/ and reference designs here: https://github.com/joeycastillo/Sensor-Watch/tree/main/PCB/S...

Friendly reminder that if you are syncing your clock from marslight instead then remember that Mars, unlike Sol, isn’t always the same distance from us. Those light minute errors could mean you’ll miss the bus home! I’m joking but this is also a real thing. For an example, see this code in the astrolib port used by SensorWatch’s “movement” project: https://github.com/joeycastillo/Sensor-Watch/blob/e8f31beb70...

The Casio watches have a little buzzer and the standard SensorWatch codebase has a modem that uses it to send data: https://github.com/joeycastillo/Sensor-Watch/blob/0ad5fa4733...

Not at all. The reason the easter egg does not appear is this is not actually a Casio Module 593 emulator. It is simply running the compiled sensor watch firmware. So for those words to appear there must be code in the firmware to make it happen. And someone has sent a pull request for it! Unfortunately it was rejected due to trademark concerns. https://github.com/joeycastillo/Sensor-Watch/pull/102 The sensor watch board is not being fully emulated either. The code is compiled to WASM and run directly. Some functionality is missing. Low power states, for example: the emulator freezes if the firmware tries to put the watch to sleep. It would be nice if the sensor watch board could be ported to qemu. I tried to do it only to discover I was a little out of my depth.

Love this project, use it literally every day. Not too long ago I implemented a new interface for defining the TOTP codes from within the source code. Unfortunately that work has invalidated the instructions in this article. It works like this now: static totp_t credentials[] = { CREDENTIAL(2F, "JBSWY3DPEHPK3PXP", SHA1, 30), CREDENTIAL(AC, "JBSWY3DPEHPK3PXP", SHA1, 30), }; https://github.com/joeycastillo/Sensor-Watch/blob/main/movem... I also added user calibration to the pulsometer in order to allow it to be used as an asthmometer. It has already helped save lives. It's also got calibration and thermal compensation features which enhance the watch's accuracy to about 10 seconds per year. It's got a growing community. A lot of people have showed up to hack on the firmware. Recently someone made an endless runner game for the

maybe you're thinking of sensor watch ? it's beat watch face seems to be set to whatever timezone you configure which defaults to UTC : https://github.com/joeycastillo/Sensor-Watch/blob/main/movem...

Joey Castillo’s Sensor Watch project seems to be the only example in this no man’s land. Over 365 days on a single coin cell battery so far. https://github.com/joeycastillo/Sensor-Watch

Sensorwatch has a watch face with iso8601 weeknumber (which I did) https://github.com/joeycastillo/Sensor-Watch/blob/main/movem...

If you're a bit weirded out by the website secret pasting, I made a PR which lets the sensor watch load TOTP secrets from an Aegis export (essentially just a bunch of TOTP URIs): https://github.com/joeycastillo/Sensor-Watch/pull/95 This is the reason I bought the board. It makes me happy not having to use my phone for this.
