Controller V2.0 finished, tested, working and ready to be installed
Since the power consumption of version V1.0 was too high, a new version had to be made before I could install the system.
The transistor is still the same but the power is now regulated using a MAX5033. I have copied the diagram from their datasheet so you can see what the PCB will contain.
I will post a photo soon but for now I can already tell you that the consumption is no longer 20mA like with the LM317 but 2.5mA !!! (yes that is 8 times less). The size of the PCB is now also chosen to fit inside the timer.
