Today I finished the box, complete with snaps to keep it closed.
Of course, I need to get some foam to create a snugg lining for the RHex, but that should be fairly easy.
Since that did not take very long, I spend the rest of the evening learning how to use templates in C++ to build an encoder library that did not need a huge function with all possible pins listed in it.
I haven’t test run that code on hardware yet, but it compiles, and C++ being what it is I assume that if it compiles, it probably runs well enough.
