This is known as a Colpitts oscillator and I soldered this up last night after dinner. To my surprise it worked on the first try! With the component values I used it oscillates between 0.7-2.8V at a frequency of 1.28 MHz.

Nice! I haven’t played around with analog stuff as much as I would like, but I’m curious what was the impetus for building this oscillator? Are you doing electronic synth stuff?
1.28 MHz is about 100x over the limit humans are capable of hearing, so it’s unlikely this is for a (musical) synth :)
I’m also curious! Been thinking of making a synth myself even though I don’t know the first thing about doing so haha It’ll be a fun learning experience if I do!
Dude me too! If you ever do please post it here, I’d love to follow your process!
