Once again, as I closed the calculator window open to multiply hexadecimal numbers, I thought "why isn't there a physical calculator for programmers?"
Does anyone know any?
Now the main thing for me is not to get sucked into this trap and start figuring out a circuit on #attiny13, looking for really good looking buttons and low-power indicators, maybe solar cells... NO!

Great, the prototype is breathing. This thermometer (D18B20) seemed to need at least 3.0 volts and I had to use a step-up dc-dc (that thing on the left and below #attiny13) to make it work even with a dead battery at 1.2 volts 😜
I need to find something to make the indicator contrast.
WINSINN low-noise fans arrived, a couple of days early: I practically figured out #attiny13 and now is not the time to redo the 3D printer😜
