Hi all,
First post here.
I have a clock project that I am working on. The movement takes a AA battery, like most analog clocks do.
For this project I am also powering a DC motor with 12v. The power supply is a 12v dc wallwart. I bought a buck converter that transforms 12v down to 1.5v to power the clock so I don’t need a battery.
I am wondering if I could install some sort of rechargeable battery in the clock and run the 1.5v to it - which would power the clock as well as keep the battery charged and in case of a power outage, the clock would continue to run off the rechargeable battery.
I’m sure it couldn’t just be that easy. just hoping it might be accomplished somehow. I know rechargeable AA batteries are usually 1.2v instead of 1.5v so it would probably get overcharged.
Any ideas on something like that?
Thanks
