![]() This is starting to be the 1337 version of blinky.Block diagrams and explain how these work. Article series for the synth – on modules and theory of operation.Basically Stephen characterized the Zener Diode leakage current!.Plot of IV curve now matches with data sheet. Lower frequencies were really sharp, higher frequencies were flat.The Zener diode was installed to prevent over voltage of the ADC.Zener diode – Zener diodes leak – caused huge calibration issues with synth.Frequency doubles for every ½ volt you put in for the VCO (Voltage Controlled Oscillator).Audio clip of before tuning and after tuning. ![]() Bad pinout designs for ICs can cause unnecessary vias in board layout.
