I *make* them precise by going low then add some nichrome wire rather than having my kids spend hours binning them. You need crazy values sometimes anyway.

Sounds like, here, you’re saying even 1 bit would do. Did some research and…
Check out picrel! Looks like 1-bit DACs are actually better quality than your old multi-bit DAC idea!
Eye opener for me. Anyway, yeah, so all you need is 1 GPIO pin, and no ladder network snd you should be all set.
