This is the system architecture overview of the current hardware.
For the last two years I haven't done any work on the project but I'm using the hardware every day.
I have a big list of new features and modifications I want to realize but there is no time to.
I also want to clean up the source code and push it to GitHub but it's still in progress.
At this point, I do not selling the hardware, you can get a PCB on tindie, but I can not promise a fast delivery.
