Self Sustaining Steam engine with auto temp input
This steam engine is self sustaining up to 145 units, All you need to do is input the desired boiler temp you want and let the very simple microcontroller's and pid's do the rest. Remember adding a bigger load to the system will decrease your maximum sustainable temp. So mileage will vary on your application. I hope this will help on your journey into steam engines.
Like always free to use but if you use it in your builds and post them I wouldn't mind being referenced.
Enjoy
