Joule Thief 101

Wow, maar 2 dagen weg en zo een: ......................... Resonance, klasse!

Blanko = Incognito: 122 stemmen, kippies!?

Contributing: + or - = 21 stemmen, Connected

Why so many only blanc / nick without force only reactive, any fundament.

These are comments from the peanut gallery and you can ignore them if you want.  I will not get involved at all in your toroid resonance discussion.  Just my two cents for the heck of it:

The peanut gallery you say
Lets have a look at who the peanut is here.

I am pretty sure that if the base resonant frequency is 3 GHz, then you can only go up in frequency to get a harmonic resonant response, and that itself will be attenuated.  You can't get lower resonant responses, that doesn't make sense.

What did smOKy say?
Quote: most of you do not have fast switching transistors that can hit the 3Ghz mark.So, as I stated before, we look for resonant nodes at lower frequencies.
How do we find them?.

Resonance guru MH--do you not understand this,as it seems very straight forward to me.
If our child on the swing has a resonant frequency,can that frequency be maintained if we only give him a push every 3rd swing,or 4th swing,or 5th swing?,while adding the needed energy to maintain the amplitude of each swing.

The fundamental (no pun) point being that the toroid can only potentially resonate at harmonics above 3 GHz, nothing below 3 Ghz.

The fundamental point is MH--you missed the boat on this one.

End of the peanut gallery - good luck Mr. Resonance Guru.

I thought you were the guru on resonance MH?.
But it seems this one has skipped straight over you head !again!.

The correct timing in an ICE engine is not "resonance" and it has absolutely zero to do with the resonance we are discussing.

Oeps: Sure?

Than why is this 2-stroke: https://www.youtube.com/watch?v=1zDmlOYiaTI

Running with only a pre-ignition from only 1.2mm this rev/min, while a 4-stroke in the same tuning ignite over 30-48 degrees before TDC?

Why we did go (partly) from Cast to Forged pistons?

Is the Fuel explosion a lineair expansion for the piston?

MH Knows the answer to this question , but he's booked up until JULY now .
you'll have to get in line ...no cutting.[Webby already tried sneaking one in ]

ResheeshMHButswammi has been enlightened.. he is a  Much Higher Power now and has no Mortal appendages
so he can't hear you anyway !

Note
he actually may not even be on the planet ATM ,something about a StarTrek sequel and resonating  "Q" into another  dimension..??



however in my ignorance [having not yet attained the enlightenment [can't find the matches ??]]
I am amazed that 3hp per cubic inch  [21--24hp on a 50CC] on a normally aspirated motor with a  cork in the tailpipe
is possible.
