Another frustrating day at the job. I needed to find something to compensate the boring and frustrating days in my job, so i started diving into electronics. This was something i learned nearly 15 years ago, while before this education i always fiddled around with electronics for a very long time. I think i started my first electronic experiments in the age of 6 years or so. While always loving digital electronics at the time of my education, i never dived deeper into analog electronics. Sure, i could use Ohm's law, knew basics about semiconductors, but the knowledge to build a synthesizer was not available. So on this day, i started using my favourite search engine to find some circuit ideas, i built them on the breadboard and tried to understand everything that happens in the circuits.
My first oscillator was a simple transistor sawtooth oscillator. No way to use 1V/Oct on this currently, but at least it worked. To get this far, i just pulled my old electronic components around, a fresh beer and some tools to the living room and started this project while watching TV :) I wanted to create a sawtooth oscillator, that doesn't provide a perfect output, you can see this on the rounter shapes of the waveform. I wanted to create a transistor VCO for this, but after those tries, i had to see that the circuit is really unsuitable for a synthesizer oscillator covering several octaves.
