My wife has this clock she loves but it chews through its battery a bit too fast. She has tasked me with converting it to a plug in unit instead. Its normally powered from 1 AA alkaline battery. At first I was just going to ditch the battery all together and use a old phone charger with a lm317 but figured I could maybe keep the battery around in case of power cuts. I drew this out to get started with but I don't know much about this type of thing. Would the following be effective enough for what I need? Is D1 even needed, I feel it may be unnecessary since the battery supply is juts 1.5V.
