Stephan,

both resisters are 10ohm 1/4W r1 cool r2 HOT


I am puzzled still  by only that

Hello,
Back to your first circuit board (without inductors and replaced bulbs with 10 ohm 2 watt resistors). Measured c1 and c2, c3 and c4 in steady state. C1 & C2 are paralleled, C3 & C4 are in series. OK, the Paralled caps are 11.59 volts. C3 is connected to ground measures 3.51 volts and C4 measures 8.08 volts. Humm.  Turned on circuit switching.. measures the same. Placed a OSCOPE on caps. C1 lead always connects to ground, measures NO Chopped waves at all. Of course C2 did by about 5 volts peak to peak. What bothers me is that C4 is always lower then C3. Actually if left for a while, C3 will turn negative while C3 is positive - adding them up gives paralleled c1 & c2 voltage.

SO... maybe the inductance 'peaked' or distroyed my 50 volt caps...  going to order new ones, maybe about 8 this time, and keep the resistors in the circuit with no inductance.

Very strange... never seen a cap actually reverse it's self while slowly discharging.

Hi People,

Stephan,
I made two of the 8ohm+2-1ohm 10ohm resisters, and somemore scope shots.

Hi People,

Here is a photo...

Okay, Dr. Spark,
now with the diode and the 2 x 10 Ohm resistors,
things have changed.

You now have around 1.2 Volts at 10 Ohms= 0.12 Amps
input current.
That means you have around 10 Volts x 0.12 Amps= 1.2 Watts of input
from your battery.
Now you burning up at R1: (1.2 Volts) ^2 / 10 Ohms= 0.144 Watts of heat power.

Now at the output you have , when we fold and integrate the waveform
around 2.5 Volts at 10 Ohms, that means we get a heat power there of
(2.5 Volts) ^2 / 10 Ohm= 0.625 Watts.

So now you see, why one resistor burned almost up,
when you used just only 0.25 Watts types.
The R1 only comsumes 0.144 Watts , thus it is just lightly warm
and is lower than the rated 0.25 Watts.

But R2 burns almost up, cause it gets 0.625 Watts, which is more than twice
the rated 0.25 Watts...

But all in all the input power is much higher than the output power.

Please try it again with
R1= 1 Ohm and
R2= 100 Ohm.

Many thanks.

Regards, Stefan.
