I began working on this project in earnest back in October (2021) and I've kept a fairly detailed login the source code repository.  I decided to share the project here since it is an evolution of a previous project hosted here on hackaday.io as well.

There's still a lot to do but the project has reached a level of maturity that most of the major components are functional.  The notable exception is a portable power supply (i.e., batteries), but the system is useful without them, and I still need to narrow-down exactly what I want to use in the power supply.

Along with the hardware I'm developing a number of programs to make using and managing the cluster simpler.
