I'm currently working on putting together the PLL circuit from Stan's patent. Here are the outputs that I'm getting so far. More to come!!!

Have you replicated the Stephen Meyers 3 phase , I am not good enough with this sim , or my comp is too slow to sim it .
Hardkrome has the VIC with PLL , no news of him yet .
-
Iv have built it in my simulation program but cant get the results that they show in the patent. The only way Ive gotten the waveform like in the patent is by a totally different circuit.
-
Plz post a pic of the circuit and what it shows .
-
its a pretty simple circuit, heres a screen shot of it.

was the dielectric value of tap water and conductivity considered when modeling the capacitor? i've found this to be the largest problem in achieving a resonant-charging waveform in an actual setup.
-
Yeah wheres the parrallel resistor , put something like 20-200 k
-
you can put a 10k, 20k or whatever value resistor in parallel with C1 and nothing changes. You still get the "Ringing" effect.

more like 10 ohms and i'm sure this will change the effect ???
-
yea a 10 ohm resistor changes it back to a basic sine wave.

I did the follower haithar .
Take 2 stainless spoons , take my multimeter .
Take tap water , add a bunch is salt , shake water , insert spoon and I was still getting 10+ k ohms

I'm also working on another circuit that will Auto-Tune to the resonant frequency of it's load. So far I'm getting good results in my simulation program. Here's a screen shot of one output from one setup, as you can see it also has the "Ringing" effect.

Looking very good, guys!
We have many options to get resonance with like 1khz. If we size the cap bigger and the coil smaller or vica versa.
I have a question: Stan said that the L must be higher then C. Why?

yes with a multimeter. but try a 12V battery connected to an ampmeter and then to the spoons. after a few seconds the current will rise heavily.
my tube cell was in the mega ohm range when measuring but pulled an amp easily at 12V (tap water).

dankie
You got that reading because the multimeter don't test over 1v so water still behave as a capacitor.
