Build a simple AF Sine Wave Generator.

Simple, sweet, and useful. Boomer wanted to see it, especially after he helped me get the values of the RC Filter right. (Saved me a trip of digging through my college text books.)     Go ahead and download and build with leftover parts.  https://archive.org/details/555-timer-adj-af-generator-schematic
I can't decide upon what's worst, young and stupid, or old and chemically dumbed down.

Thank you, that's a circuit like I've never seen in electronic instruction and circuit cookbooks, where you usually get something like a phase shift oscillator, or one with stability locked by the resistance of a light bulb filament.
