Title: Build a simple AF Sine Wave Generator.
Post by: ThaDood on July 23, 2020, 0620 UTC

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

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.
