Pick three sensors: the one you want to build with, a second you'd be glad to work with, and a reach from Mr. Reasy's advanced bench. Pairs are set from these picks. Every sensor below prints a number. The meaning is yours.
Submitting opens a GitHub Issue with your picks already filled in. That rehearses the Issues you'll leave in the silent rounds, and it gives us the GitHub username your team repo needs.
The sensor you most want to build the piece around. From the browser or the shelf.
A different one you'd be glad to work with. Also from the browser or the shelf.
From the advanced bench. Lent out only after a simple sensor already works in the browser.
