Hi HM,

WELL DONE, DUDE!
Welcome to the club of alternator animals!
Now you see why we are happy with the alternator
and why we continue to replicate these results with
a non moving solution.

Thank you guys ;)
Here are some other waveforms I got today
Modulation @ 41khz
look at the harmonics on top they are oscillating at about 1mhz :o

it looks like you're getting ringing. hrmmm, play with the pots more, does your circuit contain diodes like in the lawton pdf? also, do you have a 800 to 1000 ohm and 220 ohm resistor driving the fet? im not sure why you havent already hit harmonics.

is it touchy to the regulation or not? if its so touchy you can hardly even set it then the caps across the rotor is bad or not connected properly. i cant wait to get my fets again and rebuild the circuit, waiting on my fets still.

hi hydro
the circuit is exactly as per the beta version http://ionizationx.com/index.php?topic=140.0
pots are not touchy at all.
I have 2 caps 10,000uf electrolytics on the rotor

What should the harmonics frequency on top be when in resonance?

The only difference are the 2 cap of 10.000uf...
I use one of 1000 and Hydro does it with 470.
Maybe worth to try a different cap on the rotor?

i dont even think i've ever seen a 10,000uf cap, where did you get that thing the army???? lol, if thats 10,000uf then thats a cap id like to get my hands on, hrmmm, 450uf discharges very fast so does 1k caps, but when you get to 3 and 4k and on up those things are like batteries or sumin..

i wouldn't think the problem would be in the cap, i don't know.. but i know if i get this harmonics wave and stevie gets it,,, you should be able to also!

Stevie, can you confirm that you did get the squarewave similur to whats in the picture? and did it have harmonics at the top??? thats what i seen...

Hydro,

i confirm the wibbeling and wobbeling on top of the squarewaves .
There should be some picks of me on this forum that confirms this.

Hi guys, there are harmonics on top. I was not seeing them on top of the square wave because I was modulating to hi @ 41khz.
So I lowered the Modulation to 2khz (the lowest your circuit will go). and wollllaaa. they are now showing up !!
