In the beginning I wanted to invent the "perfect control system"

The two O2 valves with controller

More details (hopefully) soon ;-)
Started four years ago, finished also the main controller, but put the project on hold.
By experience of more than 100 CCR dives, I believe diving "by hand" than "fly by controller" is safer.

Maybe I will have an simple additional "Set point based injector" f.x. for 1.3 ppO2..... lets see.
