I wonder if you’d get better mileage out of a high efficiency 12v brick, and a 5v and 3.3v DC-DC converter? Without changing your hardware out for a NUC or Raspberry Pi, I’m not sure if you can really go lower power. Maybe install a solar panel on your balcony for free electricity lol
They’re also in denial about it making you dumber if you smoke frequently. When I still smoked, it became obvious to me that my thoughts were slower and I’d have trouble finding the right words when I started smoking nearly every night. Took a T break and cut back to weekends only and the problem went away.
