it would be important that loops in cores not be conductive; and hence spaced... if your ferrites are conductive; I assume some ceramics aren't.

Okay Every time I see a schematic like laser saber's and TK's I go rewatch the video... the foil connections are not part of the higher inductance coil.

Which means, given 2 coils, and 2 foils, and 1 coil not connected to a foil at all... means the other coil is the only one connected.


THe fist foil is cut, and it is attached to a wire that goes deep into the coil, and is somewhat not near any other wire... then the primary which is from 2 long leads...


someone said my picture was a joke... I don't know what your source is for the schematics but they're still not correct...

Cool! 

You connect 100farad small super capacitor and it will run for days on one charge but the light intensity is low

Looks nice Itsu... you are off to a good start I think. You can already see one thing: your mosfet isn't really switching at all, the Drain is staying at Battery voltage, yet you have oscillation bursts and the beginnings of a sinus signal. Do you have the larger inductance on the 34063 side? If not.... try it. Also try sticking an NPN transistor in there instead of the mosfet. B=G, C=D, E=S.

The schematic in that nice format is, I think, originally verpies's work, and it has gone through some changes, as you see. My last version is still working strong, drawing about 10 mA, making the approved waveforms, humming the ferrite, but the LEDs still go out when I pull the power.

Yes, i was wondering what that MOSFET/Transistor is doing there as all the symptomes (oscillations, blinking leds, humming transformer) can be seen without it switching, so i guess these symptomes are not what we looking for.

I swapped the transformers severall times and ended up with the larger (i have 1:3) inductance at the 34063 side to come up with this present signal
In the other situation (larger inductance at the inverter side) i have mainly evenly spread higher frequency pulses which give no reaction at all on pin13.
I will use transistors as well in the next tests.

I followed your testing with the 4069 only (no 34063, no coils) using the FG as input on pin 13 and could recreate those same signals, only my supply voltage needed to be more (between 3.5 - 4V) to get these same results.

When i receive my pot cores, i will double check on the winding/construction of the coil/foil as like d3x0r says, it could be constructed wrongly now as i have it (like in the diagram).

hi Menofather,

Since you are able to understand Akula words better than us why not you try to replicate the device and then show us where we had done wrong.
I will be happy to listen to you after your successful replication."I am still learning"

Because you replicating, I working on other divices and I not have that wire. I not beleave that here enouch information to replicate me sucsesffuly, but others belive and replicating and maybe more know how 14 ping generator work and in electronic. They bulded that schematic, so them easily something change, I not build that schematic, so me harded make this schematic. If somebody not like building how I advicing, then can not build.
