Well, they are better than the patent schematic for sure, but I'm not entirely convinced they tell the whole story.
It clearly shows the +voltage going to the 47K resistor and all the way up to the + power rail that goes to all the IC chips that's on the board.
Which power rail? 12 volt or 5 volt?
So what I need is an accurate schematic to sim and build boards from. The patent schematic is almost useless.
Nowhere have I seen before a 22K resistor acting as a feedback loop with a small disc capacitor connected to the loop pulled to ground making it an RC filter network.
Then there is the issue of the rectifiers. The only rectifier in the photographs is a single 5 volt jobbie, so I'm guessing all of the driver circuit and even the PLL runs on 5 volts, not 12 or 10 or anything else.
My hunch is this driver circuit is a little more special than the average bear would think, so I want to get it right and have that piece of the puzzle out of the way, so we can focus on the VIC itself. I wouldn't be all that surprised if HMS had a proper driver, his VIC would take off and run just as it is; maybe others too. Probably not mine, but that's another story. I'll cross that bridge when I get there.
A piece at a time Ronnie. The closer we get to having the correct setup, the closer we'll be to actually understanding this beast.
