Hmm how amusing, what bat cave did you get that from? the only bit I know is relevant is the coil resonance, we are really more concerned with transmission waves and harmonics, and static electricity and ferrox resonance, and of course where the energy comes from, any real ideas ?

The answer is within this database if only we could remove all the rubbish and irrelevant clutter from it. This is now a hard ware build forum, with the deepest respect could you please re-post your possible workings of your device else where..(another thread) perhaps.

Many thanks.

What a bullshit, you dont can read he don't sold nothing he has bought !!!

I don't understand what you're saying here, please re phase.

The photo looks like a John Serl rotary magnetic device, I haven't seen one working since the Russians published information and a short film on this device, you really need to see this working before you invest any capital on this machine if indeed it exists as advertised. Again it's an advert and of thread.

It's really a constant battle keeping this tread on track with the constant input of none relevant stories any one any ideas to get and keep this tread on target?

  Itsu:
  Ok, I've tune the device by adding the brand new fets, and the small snubber caps to the fets. While running on a 12v, 7ah battery.
Now the readings show as close as I can get it to the 1/2 ringing frequency. It's at 2.3 and 2.4 divisions, at .5us. So, 2.3 times .5 is 1.15. Calctool give me 869.565KHz.  Correct?
   I don't know if ringing frequency will change if using the 24v PSU instead of the 12v battery but I'll find out soon enough.
I just don't want to burn the new fets, just yet. The voltage readings are running under 200v using the battery.

   However, if I add any other caps like the ones at the 3t coil/cap (other than the 0.47uf), or at the grenade output before the rectifier, the above tuned frequency changes.  So, please let me know if you think that this is ok, or any other suggestions you may have.

Nick,

ok, so if your ringing first top peaks are 2.3 divisions apart at a 0.5us setting, then indeed the time is 1.15us which is 869,6Khz

This ringing frequency should not change when going to 24V, but we are not there yet.

Please give me the value of the cap that causes this halfing of the ringing frequency.

I see the posting at the same time [sorry]@@ maybe start a new topic to discuss this amongst your group if it really seems important ?


to Alien


respect ??


agree to the boundaries ,the purpose ,the goals ...
maybe a moderator ?

I know a guy who knows a guy  [ that sent an Oscope to a fellow here],

that fellow has a lot of experience moderating at another forum [DOG] ,but over here it can be a handful, social graces, between different nationalities , behaviors ,attitudes...etc etc.

maybe the serious builders can set up a spot here ?
a board which either has limited participation or access ? all can view but member participation would be determined by the group??
verpies had pondered this in discussions [how to??]

apologies to the Dog [Dog one]for throwing his name out ,but he is soooo good at what he does [moderating at Russ's place

and the less we trouble our host the better .

maybe just a board that the moderator/manager  can add members to ? serious fellows never break the rules in a group, so really don't need moderation

??

just some thoughts

but mostly gratitude to the fellows here who keep at it...
