RESONANCE EFFECTS FOR EVERYONE TO SHARE

[duff]

I don't have anything of real significance to report. I have been refining what I have and trying a few variations.

I found that changing the wire size of the primary resulted in an increase in volts out and the resonant frequency decreased.

Changing the wire size from #28 to #24 resulted in the voltage output going from 4.521VDC to 4.705VDC across RL.

Wire: #24
Turns: 93
Height: 2.185", 55.5mm
Inductor OD: 3.15", 80mm
Inductance: 520uH
Resistance: 1.97Ω

F= 196.6KHz
C = .00118uF
V_Capacitor = 155 Vpp
V_out 4.705 V_DC
Z_in = 138.6Ω


I tried adding 4 taps to the bottom of this inductor with 7 turns between taps. What I found is that the voltage output across RL dropped as I moved up the taps, and the impedance increased meaning my inductor was too short.

Since I'm out of #24 wire I'll have to order some more which will take a few days. I have some #10 magwire but that would be a drastic change in inductor size.

Replacing RL (66.6Ω) with a 100ma lamp results in the lamp burning a full brightness. Something to note about using lamps is the resistance changes with current.

Resistance  Votage Drop   Current
                   Across Lamp
2.65Ω           0.0                  0
9.158Ω         0.4579V         50ma
23.35Ω          2.335V           100ma
25.09Ω         2.760V           110ma

Because basically the SG output of 50 Ohm is loaded by a series resonant circuit that is further loaded by the transformed bulb or your transformed 66.6 Ohm resistance, the big mismatch seems to come from the 50 Ohm that is in series with the coil:  if you consider the loaded Q like (2pi*f*L1)/(R_L1+R1+50)  then you get Q=1056.43/59.1=17.8 and this is loaded further by the transformed load of 66.6 to your value of 2.5, agree?

Yes, that sounds logical to me.

Hi everyone,

I know things have been quiet for some days now but don't think the topic is dead. What we are doing at this time is re-evaluating the direction the research is going to take.

Once that has been done we will let you know by posting the new test results.

Thanks for all your support and interest.

       Please checkout some of Tesla's work.  Below is a post I made couple of days ago.  The second half is a quote from Tesla under questioning from some lawyer.  If you learn to couple your load and allow the waves to go undamped you should be good to go. 


    The simple charging of a capacitor can run with gain.  Tesla told us how a loong time ago.   Charge her up slow.  Let her go fast.   Make sure things oscillate a bit from your hammer blow.  Mother nature remembers.  What SM was doing is no different.  Charge up the cap.  Dump her into a  helical resonator.  Tap the current so you don't screwup the primary oscillations.  You can throw an arrow at a target or you can invest it into pulling a string on a bow.  Which is the biggest bang for the  buck/target.

Yes; I charged the condenser with 40,000 volts.  When it was charged full, I discharged it suddenly, through a short circuit which gave me a very rapid rate of oscillation.  Let us suppose that I had stored in the condenser 10 watts.  Then, for such a wave there is a flux of energy of (4 x 104)2, and this is multiplied by the frequency of 100,000.  You see, it may go into thousands or millions of horsepower.

Thanks for the input sparks

Pun intended ... I hope you don't mind. We will get to it soon.

Thanks for sharing
