My First (Homemade) Analog Synth

I’ve been noodling around with circuit bending recently. It’s pretty fun turning toys into noise-making monstrosities, but you don’t always have the fine control you want, and sometimes it’s just fun to make things from scratch.

I started reading about 555 timers which can be used to generate tones, LFOs, or really run anything that needs a clock. I’m planning on building some step sequencers to add to some of my music toys, but for now, here is my first analog synth. It’s made from just a few parts which cost only dollar or two. It generates a nasty squarewave, but it’s fun lol. I need to figure out how to get other waveforms. Right now I can only modify the duty cycle, and it seems in some “modes” the duty cycle changes with the frequency. I think I can rewire it to be stable, but I’m just learning.

Anyways, here’s a few pics and some audio.

It seems to me that if you play around grounding and “ungrounding” the closest capacitator with a switch you should be able to go from square wave to saw tooth. How high is the output?
