Of course I’m still around, except for 1 dosingpump and sometimes a jumping date/time the controller is still working perfectly for me :)
Even the screen is still working after 2 dips in the water and a broken touch cable
My best guess would be that its all somewhat the same in terms of electronics, Just the case is different.
I currently have set up my Eheim feeder with the NPN transistor connected to the feed button.
But once I get my hands on one I can check if the internal circuitry needs 4.5v or if it runs on a lower voltage and the 3rd battery is just there for capacity reasons
Rechargeable are 1.2v generally so that would be 3.6v at full charge and 3.3v when running empty.
As for the eheim, it should work with anything between 2.2v and 3v
