2002 oscillator drone of doom is a beginner electronics project that encompasses the spirit of the 1000 oscillator mega drone but with 6 oscillators, it has a detune knob in the middle so you can detune all of the oscillators and bring them up into crescendos, self assembly is required and also component sourcing however there is a list with links available on the build page.
Here is a build video to take you through the steps of making it - click here
