So how much power ...

So how much power is this producing?

good job man .... ...

good job man ....leave the noise its gonna be there when we build the damn thing , we will know it is right !!! LOL

what is that ...

what is that ringing

The toroid is what is causing the ringing, so to get the power with a ferric core you get the ringing. Try an air core for no noise.

what can be done about the high pitch squeal?

Lord! My ears are ...

Lord! My ears are bleeding!

very high pith noisy... thats y i fast ff.,,, removed the NOISE!!!! f u want to share from ur heart...

as sekudær coil, I have developed a litzwire thread consisting of 10 x 3 meters copper wire, I reached 95 turns around the ferit core 95 x 10 = 950 rounds. I have no primary yet. well done. the gills to use and get back again.

The sharp noise was ...

The sharp noise was disturbing but, Good Work, man. I'd like to see the schematics. Experiment's my middle name

TIP: record over ...

TIP: record over the original video with your comments.. get rid of that deafening ringing noise.

good video

is that aliasing or does it really make that noise?

putting this ...

putting this outside would help.

so glad i didn't put on my headphones on yet

Sorry but I have to ...

Sorry but I have to agree with everyone else, that high pitch squeal is painful to the ears.

I came hear to pleasure my ears with a resonating circuit :)

play with multiple capacitors to eliminate the noise. Also why have you chosen to put the bulbs in series rather than parallel? You could reduce the voltage needed while drawing the same amount of millamps.

I was thinking ...

I was thinking potting the coil in a resin may reduce or eliminate the sound, but i'm not sure exactly where the sound is coming from.

damn I'd love to ...

damn I'd love to hear and watch it, but ringing is too much :( looks interesting though

The dual of an ...

The dual of an inductor is a capacitor. If you can transform your circuit to use a large (electrolytic) capacitor to form the oscillating circuit, you might get the same result with no sound generation. Another solution to the whistling is to increase the resonant frequency way above human hearing. Of course, these are some of the principles behind ordinary inverters.
