BTW npub16mtxp68k8c3p2sj0wzhagt3kd8ywkvzlkfyt3vrx9cahzfz000vs8dpnwy (npub16mt…pnwy) I'm working on a new version of my Portable CO2 monitor with the goal being that it's easier to hand assemble and uses even lower cost parts:
CH32V003 MCU (~20 cents)
ST7735 160x80 color LCD $1
SCD40 sensor ($10-12)
