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?
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!
