Hi Robert,
Well, I did not study the motor pictures, I watched only your recent schematic where coil 1 and 2 is shown and read your description on the third coil so I answered accordingly,...

Hi Robert,
Yes, I did not consider the lack of the lamp load may cause damage to the lower MOSFET, sorry.
Would like to ask about the timing of the 3 switches. What I would do as timing is that I...

Hi Robert,
Your coil 3 may form a resonant LC tank circuit with cap bank via the lower MOSFET's drain-source (nanoFarad) capacitance and this may explain why the current meter A3 (652mA) shows...

see answer to question B in my above post.
you can use the usual diode bridge (that include slow speed diodes) for the 50 or 60 Hz down-transformed mains voltage, no need for fast diodes....

Hi Alexscg,
Just connect the control pin (the wiper) to either pin 1 or pin 3 of the pot, does not matter to which. This way you will have a variable resistor from the full pot value down to near...

I believe such single wire AV plug has the "second" wire via a capacitive coupling which is 'structural' i.e. your air core coil is 'open' to the enviroment nearby, making near field EM waves. I...

Hi aaron5120,
I also use Firefox (v19.0.2) and every video from Netica plays nicely as usual. (Just checked with Internet Explorer (I use Windows 7) and no problem with it.)
This is strange indeed...

Hi Netica,
I think you have built an excellent replica of the Fernando force multiplier as far as the available details let it. Unfortunately your measurements show a COP of less than unity if I...

Hi,
That core seems to be good for your task. Have you considered using an audio power amplifier IC? there are some with much higher power bandwidth than the 20kHz audio 'limit' set for Hi-Fi, here...

Hi janost,
Increasing the number of turns is a good idea, and consider making some taps on both coil halfs if you can to have a more flexible test range (matching).
Also if you happen to have some...

Hi T-1000,
What frequency do you want the inverter to operate? If in the wideband audio range then you have to build or buy an audio-type power transformer I am afraid, because the normal laminated...

Could explain how you imagine swapping the core with magnets if you mean that? The best would be again a simple drawing if you do not mind, unfortunately I do not get you what I indicated...
