Finally, a scope shot over the 4700 μF cap and no shunt in the circuit

@ Stefan (hartiberlin) and all interested parties:

I also managed to measure over the 4700 μF cap without any shunt in the circuit (so that the original 160 Hz and about 0.7 mA power consumption at 12 Volt are achieved).

The trick is "AC setting" on the scope to overcome the 12 Volt offset. The spikes are very short, therefore the scope only sees them when measuring at shorter time slices. Only at a high magnification (very short time slice) the true form of the pulse can be see.

The high magnification shot over the 4700 μF cap was done WITHOUT POWER SUPPLY, the circuit is running from the cap.

Many thanks Conrad.

Now we see the real "beef" !

The capacitor is slightly recharged during these spikes when the
voltage spike also goes a bit up.

So there really is a recharge effect during the first interval of the spikes,
but on average the voltage is decreasing, cause the spike voltage area below the
12 Volts line is bigger than the spike area above the 12 Volts line.

So all in all the 12 Volts is decreasing, but very very slowly.

The question is, if the energy drawn in one single spike pulse
and converted to light is higher than the energy drain on the capacitor.

It could be that Lenz law is here violated and that the
induction is putting some voltage back into the capacitor,
so that is really slower discharges than normal.

I really would like to see the same measurements from
Lasersaber, as his latest device seems to put out much
more energy than the other devices presented here from Conrad and
Lidmotor, etc....

If Lasersaber could also show how the cap voltage behaves at his latest
circuit, mabe at his circuit the voltage drop and the voltage rise areas are
almost identical, so that his circuit even needs less current and thus
holds longer the cap charge ?

Now we have to find out, what part of the circuit recharges the cap over the 12 Volts line
in this example and scale this recharge pulse up.

Many thanks.

Regards, Stefan.

Hi Conrad and all,
unfortunately you only showed one zoomed cycle of the spike as it already
begun for a few nanoseconds....

Here in this scopeshot I painted the area green, where the voltage of the
cap is rising ( very left side missing due to your triggering issue..)
and the dropping voltage area in red color, where the cap is loosing
its voltage.

So we have to find out, which part of the whole circuit is
responsible for the green part and maximize this.

This is probably a Lenz law problem to feed the counter induction voltage pulse
right back to the cap at the right time and scale.

If the green area will get bigger than the red area, the cap voltage will
rise and we will have a selfrunning system that will last and must be shut down,
otherwise it will runaway and explode...

Regards, Stefan.

Update, bifilar coil with 4 germanium diodes 1N60, CFL, this time I hope, the right scope shots:

I managed to get the scope shots over the 4700 uF cap a bit better. When I start the single shot measurement several times, eventually the scope triggers a bit earlier and shows the whole pulse. The upper scope shot is with power supply and the lower scope shot is running from the cap after 20 seconds. The pulse deteriorates while the cap slowly discharges.

Notice, the number of 1N60 diodes at the other end of the bifilar coil allows to adjust the power consumption and consequently the brightness of the CFL. With 4 diodes at 1.5 mA at 12 Volt the CFL is rather dim, with 1 diode and 38 mA pretty bright, but still a long way to its full brightness with 200 Volt and 5 Watt.

Frequency went to about 500 Hz with 4 diodes (1.5 mA at 12 Volt).

When I bridge the diodes with two fingers of my hand, the CFL becomes very bright and power consumption shoots up to 200 mA (at 12 Volt).

Greetings, Conrad

Fantastic work being done over here!

Stefan:

I think your idea of the spikes placing a small charge back to the caps is right on the money.  I have seen this a while back with my EB and supercaps charging using nothing but those spikes.  In my opinion, these spikes get "lost" in a battery but the caps store them as usable power.  There may indeed be a way to to maximize this effect and keep the ratio more in our favor.
