Build a simple AF Sine Wave Generator.
« 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

“I am often asked how radio works. Well, you see, wire telegraphy
is like a very long cat. You yank his tail in New York and he
meows in Los Angeles. Do you understand this? Now, radio is
exactly the same, except that there is no cat.”
-Attributed to Albert Einstein, but I ripped it from the latest Splatter .PDF March 2025 issue.

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.
