A project log for Video trigger generator for oscilloscope

This project generates a trigger output for an oscilloscope. It can select which line we want of the video signal (NTSC only).

I finally made this project work after much head scratching.

The result is a stable trigger output for any scope. This version uses common push button switches.

The design could use capacitive switches instead with the Q switch library. To be tried next.
