Don Smith A review...

OK Med, I'm gonna help you with replication, though my core will take about 10 days to arrive at best, it's purchased. The Extended Tesla Bifilar Coil has captured my imagination because my suspicion of the secret sauce with OU is capacitor based, add RF, add HV, add magnetic resonance. The E-TBC seems to operate in that zone and reminds me of a joule-thief/ringer with induced field while current is moving against the opposite way, and the mixed E-TBC reminds of Beardon's MEG, and DS mentioned that too. I can't wait

thanks so much ! there's too many way how we can use this special capa/coil but it's difficult for one person to do all the job, for our time and money plus efforts we have to help each other, take your time,

i did a quick research about the core you're requesting and i found this document http://www.dextermag.com/upload/Dext...nd_Bobbins.pdf, i think it's more better than a TV YOKE , at the first test i suggest you to use the diode in serial for voltage but in parallel to increase the current, try a few turn 4 or 6 for one diode, more turns say 32 turns for example you need about 4 diodes, now how much current they can handle ? if you use HER308 it can handle high current surge.

Hi Med, I am considering acquiring a Hitachi AMCC32, because it has two C cores and spindles because I can't find an economical source for a comparable Yoke. Also you have two diodes in parallel and I would of expected them in series for for increased voltage capacity?

Med in thinking about the input resonant frequency, it sounds that you are determining that on the length of a single "plate" of the E-TBC? Also the input is rectified HV so you mean pulsed DC at this determined frequency, right? Can you please tell us what your P-P voltage is for the L1 side?

Yes it's a pulsed DC, a TV flyback transformer will do the job, L1 coil is still working on electric current, after that this current will just charge the capacitive side of your extended bifilar coil, L1 will oscillate with itself, i don't know the value of P-P voltage in L1 because i don't have a high voltage probe, the measurement inside a ferrite core is difficult than air cored because the magnetic field is confined there, but i think it will work whatever the voltage you are using, remember this is the first step, we need to think about L1 because it's the energy key, if you plan to use more turns in L2 say 4 times more than L1 don't use only one diode! it be damaged immediately, HV diode is better but fast recovery is rare. so the most practical is to use the diodes in serial to get the desired voltage.


i am still confused about other parameters, so we have to test more ...

you are welcome, the mixed E-TBC is two E-TBC connected to work together, nothing is proven about this device until now... only the resonance frequency of it, it resonate at the same frequency as the single E-TBC form the mixed, ok if you have one E-TBC and divide it into two equal parts and after that connect those two part to form the mixed E-TBC, the final device will resonate at the frequency of the first coil before you divide it !

Thanks for the E-TBC fabrication pics Med! Can you please explain your definition of "mixed E-TBC", and could you please show a schematic on how you are hooking up your device to get 100W to light. If you just have hand drawings I would be happy to put them in Visio. Thanks again for all your effort!

the idea behind it is to achieve both electrons spin at real time, if you want to light a 100W bulb just one E-TBC will do the work but we still need other improvement especially the quality of L1 oscillation, tuning is needed but i am still testing and observing ..

here you are the schematic, nothing is special !

any furthers questions are welcome about how to construct this device, the following image show a 100W light bulb at full bright using only one toroidal and 6 turns in L2, caution is needed, the system is really dangerous, especially in the capacitor banks.

[med.3012]

this image show other turns :





and voila !

[med.3012]

another view of the final wire,



now this is the used TV YOKE, the ferrite have to be insulated since it's conductive



this is the first turn,




to be continued ....

[med.3012]

the following image show the connector from bottom.




finally two prepared foils




you need 4 of these connectors so each side has two contact, the final product will be like that after adding an insulator



to be continued ...

[med.3012]

now it's the time to put the cap of this connector as follow:



it's the time to make some effort !




to be continued ...

[med.3012]

at this moment i am using a connectors to connect the conducting wires with foils, it's the best way since they are available and secure a stable connection ...



the first step is to make a small hole in the foils :



connect one side of this connector, prepare your wire for this contact as follow :

some practical aspects :

the following photo show two separated aluminum foils, aluminum is available and relatively cheap, the ribbon used here are off the shelf:



the second image show the used tools :
