I was at Costco today and came across this scale., It's got all the things and was only US$18, so I bought it. For this project, I don't need most of this, so my plan is to swap this in for the electronic-but-not-smart scale that we already had and hope that I can reverse engineer that existing scale for this.

You know how Costco works, so if you are following along and think you might go get one of these for yourself, well, your local Costco might never have had it, or it might have had it for a one-off tiny slice of time.
