DIY synth “Square Wave Oscillator” with 555 timer [VIDEO]

My second synth project. I was going to try to make a more complicated synth after my first 556 but couldn’t even rebuild the 556 in the same way. I also didn’t know how the 555 operated properly so I thought myself a bit of a charlatan if I didn’t try and single oscillator synth. Emits a theremin type sound. Nice and simple to make… As long as I don’t need to solder yet…
