Got a working square wave oscillator soldered onto a board now – it’s output seems to be quite hot, but that can be solved later down the line if needs be. Now ideally I would build a VCF and then a triangle wave oscillator to slowly modulate the VCF. And then do it all again 2 more times.

Once the VCF and triangle oscillator are operational, replicating them should not be difficult – maybe an afternoons work? I hope to get the filter down today, the triangle oscillator can wait until tomorrow.

[written 4 days before gallery install, meant to be posted then. how funny it is, seeing myself thinking that I can realistically design and make a VCF and triangle wave oscillator in that time, when it took every ounce of my being to build just two square wave oscillators in time]
