If you know the number of turns on your coil, you can get a good approximation of the inductance from any of a number of websites that do the calculation for you.
I'm sure there is one better suited to your coils, but this is a start:
e.g.   http://hyperphysics.phy-astr.gsu.edu/hbase/electric/indsol.html

Hi Vortex1. I don't think that will work. From what I understand Jorge is using pancake coils,
not long solenoids. Also Jorge has said he has pancake coils connected in series for his primary, if I understood
correctly, plus other pancake coils stacked on that for secondaries.  It won't be easy to calculate his primary
inductance. Measuring the inductance would be much easier for his setup.
P.S. I have the same blue LC meter that you recommended and I find it works quite good as well.
All the best...

Jorge, it should be quite simple for you to get a fairly ballpark measurement of your
battery current, as I mentioned previously. I saw in another video of yours that you have a
multimeter. See the attached diagram on how to connect your multimeter to measure the current
being drawn from your battery pack. This will measure the average current, which is close enough
to get a reasonable idea of how much current your circuit is drawing. Use the 10 amp scale to start
because you are probably drawing more than 200 mA, and you don't want to blow a fuse in your meter
if it has one, or otherwise damage your meter.
Note: You need to plug your red meter probe into the probe jack that is marked '10A'.
The 10A scale will not be really accurate, but it is a good place to start to see approximately how much
current you are drawing from your battery pack. You can then reconfigure the probes and meter to measure
DC volts, and measure the battery terminal voltage while your multivibrator circuit is running.
If you have any questions feel free to ask.
Without doing this basic measurement of battery current and battery terminal voltage while the circuit is running,
it is hard to estimate how your circuit is performing.
All the best...

Hi Void

Yes it may be difficult, I was hoping to find a good calculator that was better suited to his pancake style coils, but couldn't.

re: AFAIK the LC200A was the best bang for the buck back a few years ago when I bought it.
It suits my needs.
There may be better ones today. I was looking for decent accuracy for the home experimenter on a budget, and I wanted a zeroing capability, and a case, not open board. You can get the same device cheaper as an open board unit w/o power supply.

Some of the better looking meters of that time had far worse accuracy or no accuracy spec. I was looking in the under $40 class. Today the game may have changed.

Ok, i made the test with my yelow multimmeter and the result was:     INPUT VOLTAGE = 5.12 VOLTS X 0.08 = 0.4096 WATTS


This result is somewhat erratic BECAUSE MY HAND MADE SOME "INTERFERENCE" IN THE CIRCUIT THAT IS VERY NEAR OF THE PANCAKE COILS, IS "SOMETHING RARE" ...!


THE TEST WAS WITH THE QUADRIFILAR PANCAKE COIL, I HAVE THREE PICUP COILS WITH THREE BULB LEDS, TWO BULBS ARE OF 3 WATTS AND THE OTHER BULB LED IS TWO WATTS, A FRIEND OF MINE SELL ME, HE TOLD ME THE SPECIFICATIONS OF THE LED BULBS.
SALUDOS JORGE

Hi Skycollection. Thanks. Ok on your input measurements, that is interesting. Your pancake coil setup seems to be
working quite efficiently then, assuming the current measurement is ballpark. Your LED lights are probably not
running much near full brightness however (unless you have over unity ). Can't really tell the actual brightness
when just viewing the LED lights in a video. Measuring output power accurately on LED lights is tricky
when you are driving them with an AC signal. I think you said your LED lights are designed for 12 VDC. If you have a
power supply that you can set to 12 VDC, you can connect the LED lights to it and compare the brightness of your LED
lights at 12 VDC compared to how bright they look when being run by your circuit. When LED lights are driven with pulses
I think they can appear brighter than if they are driven by the same power level at DC. Just my impression, I could be wrong
about that.   Anyway, your coil arrangement seems to working very well, so good job on that!
All the best...
