Russ - firstly on the diode, pretty well anything would be fine. I normally use something like a 1N4148. It's maybe a fine point - most of the time it'll work fine without the extra diode.
If you find you need such a big cap in the edge detect, then the transition-time of your input signal is too slow. The standard 555 can pull 10mA fine, and stretches to 200mA with things moving a bit slower - see the data sheet at http://www.ti.com/lit/ds/symlink/lm555.pdf for details. The output transition time is around 100ns - should be fast enough to run a much smaller edge-trigger cap, since you're only loading the first 555 with around a milliamp up or down.
I suspect that on your Hall-effect device, the output transition was somewhat slower. If you want it quicker, then either buy one with a schmitt trigger on the output or put one in yourself (you can also use an extra 555 as a schmitt trigger, which is a bit sneaky but they are cheap). I'll draw a circuit for this if you want it.
Rather than use the old 555, I actually use the Micrel MIC1455 and 1457. These are surface-mount SOT23-5 devices, with better specs than the 555 for most things and need fewer components around them. The board gets much smaller, so less pick-up of the high electromagnetic fields you're going to have when the machine is running. For edge-detect, I'm using 100pF.
Hello all.
Ive been looking to buy some COP's just like the ones John Rohner uses on his NGE. the Weapon X coils, same coils that was included in the "popper kit" displayed here. These coils are rated at 80-100k volts.
I Think they are a bit expensive and im looking for alternatives or cheaper ,used Weapon X coils.
Someone know where i could get my hands on 8 coils at a reasonable price?
Been looking at "Dragon fire" COP's but they are only rated at 42k volts.
Any idea what kind of energy that would be released in a "spark" ( 4 sparks at 100k volts) ?
Regards Janne Ström
Russ - an excerpt from a circuit that uses an astable 555 to drive a monostable. This is from an LTspice simulation. I hope this helps. I built this circuit using the Micrel parts and it works fine.Janne - may I respectfully suggest that you wait until after Dec 11th before deciding to use the same design as John Rohner? So far I know of nobody who admits to having seen his design working. At least if you try what Russ is doing you know what to expect.Quote from woody0068 on December 5th, 2012, 12:56 PM Hello all.

I was considering going on my own dime just to see their booth, I'm hoping someone here can go and give some good feedback and maybe video.Quote from element 119 on December 4th, 2012, 02:23 AM 1 week to go (Dec. 11) for the supposed big unveiling of Inteligentry NGE motors at the Power-Gen show.
Sterling said he is not going, so I’m wondering if anyone in here is planning on going?
Some doubt has been raised that any working motors will be at the show!
element 119
I have my doubts too... I mean, there's a million excuses like "the venue wouldn't allow it for safety reasons" or whatever. I really hope they break through to mainstream, not for their benefit, but everyone else. What's the best outcome of this show though? Making national nightly news?
Hmmmmm, I just checked the Power-gen website because i wanted to see first hand myself, but when i looked up Inteligentry NGE motors, their not even registered to be there...hmmm , makes you wonder don't it?
Check for PTP Licensing, their licensing subcompany. It's still there...Quote from ken black on December 6th, 2012, 09:33 AM Hmmmmm, I just checked the Power-gen website because i wanted to see first hand myself, but when i looked up Inteligentry NGE motors, their not even registered to be there...hmmm , makes you wonder don't it?
Yeah, found them.Quote from Badger on December 6th, 2012, 09:51 AM Check for PTP Licensing, their licensing subcompany.

It would be nice to have some trusted feedback on what is going on with their NGE.
Also if you can maybe get some video or pictures of the setup. :)
Please let us know if you do go!
element 119
In the Papp explosion, instead of using a spark to ionise the air, he used a hot Tungsten wire. As soon as enough air between the plates was ionised enough to conduct electricity, the capacitor charge across the plates produced the pop. This method doesn't have the same reliability of timing as a spark, so wouldn't be so good for an engine. You may be able to get the timing better by circulating a bit of the gas through a heater unit and blowing the hot gas across the spark gap. Using Tungsten (melting point over 3000°C, if I remember rightly) means you can get the gas-stream to at least 1000°C and nicely conducting. Maybe some problems with turbulence if the engine is running fast, but use enough pressure and it should work.

Hello all, well my 350 volt, 3300 uf caps came in today 10 of them, very good price, so when I get some time, I will be experimenting.:D

A closer look at the Americium 241 button from a smoke detector.
The Americium 241 button seems to be a standard product found in a large verity of smoke detectors.
This button will generate a positive electrostatic surface charge on the bucket.
The design of the smoke detector must be radiation failsafe even if abused.
The Americium 241 buttons seems safe to install in the bucket.
The button is small but powerful. More than one button will fit inside the bucket.
Opinions are welcome.
Have funQuote from Jeff Nading on December 8th, 2012, 10:12 AM Hello all, well my 350 volt, 3300 uf caps came in today 10 of them, very good price, so when I get some time, I will be experimenting.:D
Don't forget to completely discharge the caps before putting any fingers near them,
just to be on the safe side...........

“Similarly, atoms which exhibit alpha particle emission (which generally involves strong interaction between nucleons), are capable of being utilized. Although alpha decay is normally slow and have half-lives which are longer due to electrostatic barriers that make it difficult for alpha particles to escape, the present invention utilizes periodic discharges of electrical energy which speed up the escape of alpha particles and permit the reactions to be utilized effectively in the method of the present invention.”
ELECTRON MOBILITY IN DENSE HE GAS
A.F. Borghesani
Experiments on the mobility of electrons in dense helium gas elucidated how localized electron states develop when the gas density gas is increased. Up to 77 K, the density dependence of the mobility clearly shows that the formation of electron bubbles is a continuous phenomenon.
Localization of electrons in bubbles also appears at high temperatures if the density is so large that the free energy of the localized state is negative enough.
Percolation and hydrodynamic models have been devised to explain the continuous transition from high mobility states to low-mobility states.
It is shown that density-dependent, quantum multiple scattering effects modify the energy of the nearly free electron in a way that can be accurately described by heuristically modifying the kinetic theory prediction.
