ive been studying, and studying, and trying to figure out why it failed the first time, I ran across yantzers pages, and some other pages. I think i found my problem. I need a schmidt trigger!!! because i noticed, that his sync pulse looks like mine from the video amp, but my return loop pulse has lots of variations, and amplitiudes. But his looks just like the sync pulse, except the duty cycle is different.


I noticed he used a 3 lead optical pickup that was actually an IC that is a schmidt trigger. I looked up what schmidt triggers are, they take that same noisy variating signal, based on thresholds set by resistors, puts out a clean square wave signal!!! THAT was my problem .

So, i need to get that 4046, and try this approch. I got nothin to loose, except time and maybe anohter 4046. LOLz
