I have a new one going together this evening. Just spoke to Brad about it. Im using a 6mm OD ferrite toroid(input choke off a small cfl circuit board) and starting with 2t by 2t and will step up the turns if necessary incase of operational issues. The reason for beginning with 2 turns is to try and get the operating freq up to where we would need to be to get the core freq to resonate. The 3904 will operate up to 300mhz. Smoky said in a recent post about getting the core into saturation. So smaller core, easier saturation. Especially with the small amounts of power we are dealing with.

Windings will be 30awg. Very short wires so low resistance. Putting on a square of RS circuit board.

Good for you. Those little toroids work quite well.
You may want to consider other transistors though. MPSA18, BC337-25, perhaps even MPSH10 for your higher frequencies.
Also don't forget about my 6-Pad JT design for circuit board:

Nice.

Thanks, Ill try some different transistors.

I don't post garbage but speaking of garbage, how is the "resonant Joule Thief" cumming along? Anything exciting to post?

So in harmony and each is contributing, not like mostly on this forum, more clear it can't be!

Yes Cavity resonance would seem a path to results.

here is a very simple Cavity resonance device which has always tickled My Fancy.

Instead of the stupid worn-out Joule Thief ad nauseam, I suggested a project for a circuit that is purpose-designed to drain a battery of as much energy as possible, and also keep a LED lit at a certain minimum brightness. Nobody said anything, just blank stares. How about an egg dropping competition then?

MileHigh

I already have that circuit--the Cool Joule.

It will pull the battery down to less than 150mV.
It will run for up to a year on a full 1.5v AAA battery,while recharging a second.
For a higher light output from the LED,simply remove battery 2.

A very simple circuit.
L1 and L2 cannot be hooked up the wrong way around,as the circuit dose not rely on inductive coupling between L1 and L2 to operate. Each coil must be hooked to the specific
connections on the circuit though.

@ PW

Dose this look like it operates using the miller capacitance effect?

That's great, promoting a fake "resonance" device with a fake clip from a group of people that are universally recognized as fake scam artists.

Miles
Go Back to your Canadian scam promo's ,

here we have cavity resonance doing things it should not do in an ICE ,*1 HP per 2 CC's displacement.
Utilizing resonance to do this,[something you were clueless about yet felt the need to holler BS and call
Brad an idiot.

One Man's BS is another mans Curiosity ...
cavity resonance needs further investigation !

Just ask the Bug with a specifically designed cavity fist that Knocks photons out of orbit causing a 9000 C
biological sonoluminescent event .

Oh is he a proven scammer too ??

your credibility here [cavity resonance ] is non existent.

To be Clear ...I hold Witts in complete contempt .

not so ..this claim about cavity resonance and the things which are truly possible .

The Bug Pings a cavity and gets 9000 C from water .

Ultrasound pinging a cavity ......?

Wow wee, if you put air into a cylinder under pressure it helps you get more air into the cylinder and therefore you can put more fuel into the cylinder for a bigger bang. That's really amazing out-of-the-box thinking that the PTB don't want you to know about. But the actual engine itself, the pistons, the valves, the camshaft, the crankcase, the ignition, etc, has absolutely nothing whatsoever to do with resonance.

And then you roll out the pistol shrimp for the 30th time - which has nothing to do with resonance.

But the actual engine itself, the pistons, the valves, the camshaft, the crankcase, the ignition, etc, has absolutely nothing whatsoever to do with resonance.

The below linked paper is from the era where indepth research started on diesel engine's.
Once they started to understand what was going on within the engine itself,large advancements where made,and today the diesel engine can be found in race car's,where there performance is up there with the gasoline engine of the same cubic size.

High performance diesel engine's are common place today,and in the future i see them surpassing todays gasoline engines in performance and efficiencies.

As you will see in this paper from 2002,research and results are found and given on the cavity resonance inside the motors cylinder. The cavity in this case is the bowl found in diesel piston's,where resonance of this cavity plays a vital roll in engine efficiency and performance. These resonant frequencies are at the human audible range-between 10 and 20 KHz.

There is also a lot of information out there about the resonant vibration's of the ICEs cylinder wall's,and this also plays a vital roll in heat dissipation,and efficiencies.

Back when i was doing my trainee ship,there was very carful calculations made on the cooling fins of the two stroke air cooled engine,so as they did not go into resonance during the engines rev range. In the early day's,cooling fin's use to break off cylinders for no reason at all--or so they thought. But it was later found that some that were of the right size and shape-in relation to engine vibration,would go into resonance,and reach an amplitude that high,they would just break off--much the same as the wine glass reaching an amplitude where it can no longer hold the amount of built up energy.

Anyway,back to internal resonance of the ICE.

Once resonance is achieved, the standard laws that govern EM "THEORY" no longer fully apply. In electrical circuits, resonance separates the dielectric/voltage component from the magnetic/amperage component. When this happens, you are into a new electrical paradigm in which what was operating largely as a closed system begins to operate as an open system, interacting much more readily with the local electrostatic environment. Similar open system shifts occur when mechanical systems or parts thereof begin to operate at resonance.

No, that's complete nonsense and you don't have the slightest clue what you are talking about.

Dear Bob,

You naughty boy, you can't post this kind information without getting first permission, min. 5 copy and stamp, 3-6 month's waiting, this from the flying Upper-Totem-Pole.

And Right, you see, with in only 5 min. a negative reaction, Red-Card!!

WITTS, Ainslie .............. all crazy, according our balcony chicken / nickname.

Thanks, Johan

P.s. Fast jets are flying with slow burning Diesel fuel, the better LNG we let, because bad mixture with TMA, science slaves.

MileHigh · « **Reply #1303 on:** March 30, 2016, 08:49:50 PM »

It's worthwhile to point out the truth, and reject wishful thinking and fantasy talk. We are adults and not children watching a cartoon. WITTS and Ainslie are fantasy junk, and the WITTS organization is just a front for sucking money out of people. Posting your resonance fantasies and stating them like they are true facts is simply ridiculous. It's the same reason that people spend $100 on a flashlight that supposedly "never needs recharging" and in reality it doesn't work. It looks like Orbo Girl has stopped posting her weekly updates for her cell phone that "never needs recharging." At least have the courage to speak the truth among yourselves. If you make a claim that is out of the ordinary then prove it.

The "Red Card" should be the "Red Truth Card." Forget your MIB fantasies. I played the truth card, this is not the Flintstones.

Really? You apparently didn't even read the results of your Google book search.

Yeah, when the fuel mixture explodes inside the cylinder, the burned gasses create pressure waves at resonant frequencies which causes an undesirable "diesel knock." This causes the engine block walls to vibrate causing noise radiation.

They are studying ways of understanding and reducing or eliminating this problem by putting pressure transducers inside the cylinders and recording the undesirable pressure waves associated with the combustion process.

So resonance in the combustion chamber is undesirable. It causes excessive noise and certainly if the walls of the engine block are taking on added vibrational stresses that's can't be a good thing. If you could eliminate that resonance, then the energy that causes the noise and vibrates the walls of the engine block could be directed towards pushing on the pistons instead.
