Video on a oscilliscope

Exploring vector rescanning.

Found this video (it's not mine) but I'm experimenting
using the LZX modular system to do a similar thing.


Input the video signal into the z-input of your scope and supply the X & Y inputs with
ramps.

 The circuit uses a LM1881 IC - Its a video sync separator.

Here is another video using the same idea:
Creating X and Y sawtooth ramp signals from the vertical and horizontal sync pulses.

Schematic is here:
