Pluto watch R2

Refresh of the Pluto programmable digital watch from Lukas / carrotIndustries. Cheaply manufacturable in 2019.

Similar projects worth following
The Pluto programmable digital watch is a wonderful project from Lukas / carrotIndustries.
Pluto replaces the PCB of the Casio F-91W with a custom one containing a TI MCU, a digital magnetometer (compass) and a 38 kHz infrared receiver for software updates and communication.

However in 2019 it is no longer manufacturable due to it's magnetometer lack of availability as a standalone component.

This project mainly aims to replace the deprecated MAG3110 chip with the ST-LIS3MDL.
We are also going to try some tricks to make the PCB cheap and easy to get made.

Enjoy this project?

We also added a low power pressure / temp / humidity sensor. More on that soon.

Do you have a link to the original project? Everybody but me seems to know what it was, but I somehow missed it.

Nice!
I was put off by how difficult it was to source the magnetometer for the original Pluto PCB

I really hope you succeed with your project!

We already made the hardware redesign, and ordered the PCBs. Waiting for everything to get there to do the software work.

Thank you!

Yep thanks, we also made some bargains on the manufacturing to lower the costs, we'll see where it takes us. We will write a log as soon as we test the boards.
60 of them are incoming.

I just added the PCB and software repos.

  Are you sure? yes | no
