LEAP#185 Building the Böhm Stirling-Technik HB13 Small Bonsai

What has this to do with electronics? Well, nothing (yet), but there's ample scope later;-)

A Stirling engine is a closed-cycle regenerative heat engine with a permanently gaseous working fluid. They are named after Robert Stirling who invented the first practical example in 1816.

Böhm is a small(?) specialist manufacturer from Germany that's taken up a side-line in producing Stirling engine kits. When I first discovered them, I couldn't resist. So here's my build of the Small Bonsai (HB-13).

As always, all my notes and schematics are in the Little Arduino Projects repo on GitHub.
