boost from a single 1.5v cell to 5v.
To handle from < 1volt discharged cell too.
Get max out of 1.5 v cell.

There are many nearly perfect boost-
converter ICs to choose from. TI's
TLV61220, works from 0.7V up, to 200mA
out, $0.57, qty 100, six-pin SOT-23.

There's a host of excellent ICs for this
job, but you probably want ready-to-go.
Several Amazon sellers offer these, e.g.
https://www.amazon.com/Comidox-Module-Voltage-Converter-0-9-5V/dp/B07L76KLRY/ref=sr_1_10
There's a little 4-pin IC in a SOT-89-like
package that's popular in these Chinese
designs, but I don't know what it is. They
say it'll start on 0.6V or some such, and
provides good 5V out for Vin down to 0.9V.

Whoa, Legg, you are the main MAN ! Available
from LCSC, for about $0.04 each, qty 100. !!
Datasheet says starts and works from 0.9V up.
Runs at 180kHz, boost switch works to 360mA.
B version runs ext FET. C, D versions 5-pins.
