Good Morning Jeremushka,
I was looking at purchasing an AC/DC transformer, I found one, see the following: https://www.aliexpress.com/item/AC-DC-110V-220V-to-3-3V-700mA-2-3W-Switching-Switch-Power-Supply-Buck-Converter/32829978591.html?spm=a2g0s.8937460.0.0.1d582e0ecZHxyR
I understand you may want to build your own, but I figured for the price of the above unit, could be a viable alternative.
