DIY video VCO

Here are some shots of early XR2206 based video VCO experiments, the important thing with video is getting sync pulses from your SPG in to a format that your oscillator circuit wants to sync to, some are fine with narrow pulses some want a nice clean saw wave or for the pulse to hit a certain voltage threshold. This means if you don't have the skills to attempt at modifying whatever SPG or VCO you have chosen you will need sync conditioning circuits to sit in between getting the two to talk nicely.
