This video, via casperelectronics, takes a look at DIY synth building and building an oscillator from scratch. And controlling your synth with a watermelon:
Video Summary:
Learn how to make a variety of simple but flexible oscillators (tone generators) using a breadboard and just a few inexpensive parts. This video has been created with newbies in mind, but should still offer some useful info and novel tricks for more experienced builders.

I need an OMSynth!! 🙁
no need to frown 😉 The OMSynth will be available soon enough.
Awesome. How soon is soon? How much etc?
And do you have any tips for building this stuff without one?
cd40106 , the basis for so many noise maker synths
only more common is the 555
it is a pity with all the DIY though that no chip maker has brought out something like curtis chips or a sn76477 design
