Kronos -- an ESP32 Powered watch
it will have an IR transmitter so it should be able to control other projects i make, an IMU so it can do rough step tracking and and the unit I'm using has a magnetometer so it could also be used as a compass, and finally the most important part of the watch the clock it is able to do up to 100ths of a second which would be useful for a stopwatch and keep the time really accurately.

Started brainstorming what features that I would want.
Here is a list of features and components that should be able to do the things that i want them to do. first I'm needing an RTC (Real Time Clock) so i can keep time crazy idea right. The chip that i found to do this is the RV-8803-c7 which can keep time up to 100ths of the second.
Secondly i was thinking of getting a 9-axis IMU (Internal Measurement Unit) so i can do some rough step tracking and with the magnetometer in the unit i should even be able to get an app that is a compass.
The next feature that i was thinking of adding was Bluetooth and Wi-Fi so that's the reason that i picked an ESP32-S3-MINI. Those are the main things that i think I'm going to add unless i find some other things that i should add to the watch.
