I was messing with this electronics kit that I got several years ago, called Snap Circuits (From Elenco). It's kinda like Legos, but for electronics. It's technically designed to teach kids how electronics systems work, but it's actually really fun to fiddle with.
I found this project in one of the manuals, a tone generator. Part of it used a capacitor followed by a resistor. I extended this to a sequence of decreasing capacity/resistance pairs. I used an antenna coil to slightly modulate the frequency of the output sound (not totally sure how that works actually -- I just kinda messed with it until it sounded good) and a variable resistor to change the frequency manually.
I run a YT channel where I plan on talking about this but that'll come later today (on an edit to this post.) It's kinda hard to describe verbally, so I'm sorry for any ambiguity. But it's cool and fun to mess with.
