Rhombic Stirling Engine 235 Watt data logging with Arduino

Some big and many small improvements increased output power to 235 Watt.

New Burner, outside cooling fins, improved cooling system and grinding in the Rhombic Drive gearwheels under heat
(which caused excessive friction) are just the bigger changes I made the last time.

A lot of smaller changes and a few bigger (tubular heater/cooler)
are in the planning stage.

When these are successful I will make long-term testruns and efficiency tests.

Designed target power (scaled of GPU-3) was 390 Watt.
Thats the goal I want to come close.

I hope to report new results soon.

I am always happy for comments and suggestions.

Thanks for watching and greetings from Germany
