SSG Scope Shots

[Farmhand]

With a bit more playing around I have noticed that there is a limit to lengthening the coil charge duration reached at an input current of 420 Ma -


at this point the charge battery voltage is at it's highest if I continue to reduce the base resistance the input current keeps rising a bit but the coil charge duration doesn't seem to keep getting any longer and the output current doesn't rise much past 210 Ma ( the ouput current seems to have Risen with the increase in supply voltage 20v to 22v )

Here's my circuit and coil. The coil is a bit strange the only wire I have at the moment is .5mm so I split 1000 feet into 4 wires and wound them together then paralleled 3 wire's for power winding and used one for trigger. There are also three output diodes in parallel 1n4007, the globe is a 12v 2watt.


Since this photo was taken I have increased the magnets to 18.

where to place probes

Hi guys - this may seem silly, but I'm also new to the oscilloscope and just wondering if you can confirm the places in the SSG circuit where I should place my scope's probe-ground and the probe itself.

Do I need to clamp the ground on anywhere or is the little probe-end enough?

I seem to see the same signals when i use the ground or not... or attaching the ground makes a signal i was seeing disappear. Sometimes it also stops the resonance in the coils and I can't get the coils to resonant until i remove the probe. I assume I'm just putting it in the wrong place, or using an incorrect setting. I'm keeping my circuit voltages very low (3.5v - 9v) while learning.

Can someone just provide a list of like, the points to measure across and what they translate to? ie. "probe on Transistor Base, ground on Collector, shows you input voltage" (which is probably wrong i'm just using as an example of what I need). Or, is there a doc or webpage somewhere that already has this ? I've looked... nothing easily spottable to me.

Hi There,
To see the classic "h" waveform place tour probe ground on the emitter of the transistor and the probe its self on the collector of the transistor.

Thank you Lee!

I've attached a pic of the oscilloscope shot with the probe connected as you suggested. This is on my 'Rodini' solid state - which is a bedini SSG circuit with a Rodin Coil in place of Bedini's second ('B') coil, and it easily enters a solid-state resonance mode in many configurations.

So, the oscilloscope is set at 0.1 mS/div, 5.0 V/div. The signal repeats 3 times across the 10 divisions of the screen. Not such an 'H' shape, but the Rodin Coil changes things up.

Hi geminitric, thats an interesting scope shot, i've seen a very similar one here-http://www.energeticforum.com/renewa...sulfators.html

It's good to be able to see that our circuits and devices are working as intended and to see the difference a change can make.

Hi geminitric,
I have a problem with your scope waveform. This is not typical of a solid state oscillation waveform, this is more typical of a driven transistor on a 50/50 duty. The coil is discharging to a voltage much greater that the supply voltage and, if this were solid state, the transistor would re-trigger on the first oscillation below primary voltage after the collapse, therefore not allowing the damped oscillation to occur after the collapse, as seen in your scope shot. Without a clear schematic of your circuit, I can only conclude that this is not the waveform of a self oscillating circuit.

Hi Lee.

I noticed recently that if I connect my very small SSG to the same power supply wires as another SSG or solid state device the small SSG is triggered by the power supply fluctuations. I just flick the switch and it starts. It seems work like a slave at the same frequency, doesn't seem to affect the larger device at all.

This is a shot of the small ssg wave form when triggered by the supply line fluctuations,

This is the supply trace without the second slave SSG turned on

This is the supply trace with both.

The waveform of the SSG triggered by the supply line fluctuations looks very much like the waveform of an SSG triggered by your pulse generator circuit.

Any idea's how this is working? A smaller device doesn't seem to trigger a larger one.

Hi Lee, thanks for the continued input as this discussion is helping me figure out what I'm seeing. I can assure you this is solid-state oscillation; take a look at this vid to see how the device was working at the time that I took those photos.

Also, I'm still using my original circuit, which is available under the Rodin Coil Tests and Replications thread, here:

I am really trying to understand how we translate the scope waveforms into quantifiable energy measurements. Where should I put the probe and ground, to see what is going on at the trigger/input side?

Scope shots while charging to power supply

Here's something I've noticed - the previous waveform we were discussing was occuring while I had my large bank of capacitors on the charge output of the ssg circuit. Now, when I put a battery on to charge, the waveform is more typical of what I believe is to be expected.

Here's a shot of the scope across Collector/Emitter, running off a 12v 7aH battery and with the charge connected back to that battery. I've only seen this work when using a FWBR.

Scope is set to 1 V/div and 20 uS/div.



Is this similar to what you've seen?

[Farmhand]

Hi geminitric, That looks very much like the waveform from my solid state device except for the difference in charge / discharge times. My scope is set to 1/10 and i'm using a 10x probe, SS device operating at 2.7 Khz. 12v battery for input.
