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
