@Ren --The Darlington pair works well in this application. My little cheap 2n2222s are still running the CFl well into the second day. The NiMH AA battery pack is hanging in there. I might get one more day out of it. I built a second identical system yesterday but added high ohm pots into the circuit to bias the first 2n2222. This made a huge difference in being able to get the most brightness for the least amount of power.
Happy New Year ---Everyone

Nice Lid. So did the resistance increase brightness AND amp draw?

@ Carl. For the two ignition coils to be out of phase with each other you would probably need a flip flop style circuit. Ive been trying to gather parts for one using PWM. Gotoluc's circuit is like this I think. It flips polarity as well, but that is just a matter of how it is configured. We should be trying that on the coil as well I think

@ Carl. You know that the maximum potential between two equal Tesla coils are when they are 180 degrees out of phase from each other?

Ren......that my be it. I was using 2 ign coils when I got the effect.

The Darlington pair

@Ren --The Darlington pair works well in this application. My little cheap 2n2222s are still running the CFl well into the second day. The NiMH AA battery pack is hanging in there. I might get one more day out of it. I built a second identical system yesterday but added high ohm pots into the circuit to bias the first 2n2222. This made a huge difference in being able to get the most brightness for the least amount of power. The most interesting thing happened when the first system (not attached and 2 ft. away) reacted to adjustments made on the second. One was talking to the other in Tesla language. You could hear it and see it as the frequencies changed.

@ Vortex I am getting the feedback signal from the ignition coil and on the second setup I used a 1/2 strip of aluminum foil around the coil instead of the 33 turn wire. It seems to work just as good. Without that my cheap 2222s will not trigger.

@Ren --I think that a Tesla coil from that web site is a good idea at this point. Either get the plans or the kit for the "Mini".

For those that live in the states can I suggest trying some of these?

Tesla Coils, Plans, Parts, Kits

Im interested in the mini tesla lighting machine. Specs say 12v 300ma input, 40 to 50kv output, which is probably double the output of the ignition coil. Id be interested to see how it is setup.

Also this one Universal High Voltage Modular Power Supply....

The micro mini mite looks good too, probably needs a bit more current considering it comes with a 12v 1.5 ampere step down transformer for 120vac.

Also, something else to consider is this. Does higher output voltage give more light? You would think so yes? So what about voltage multipliers? We are going to need some pretty sturdy diodes for that, but it isnt out of the question....

After reading the postings and experiencing the HORROR of having experiments not replicate because of transistor inconsistencies, I decided to look back at why transistors work in the first place. I found this video posted on Youtube by AllAmericanFiveRadio. It helped me and understand a few things. Specifically how the 2n2222 is working. The video goes into triggering it by touching it with your finger and rubbing you foot on the carpet. It also shows how you can amplify this signal by a resistance between the base and the collector (bias). This is very very basic stuff but important to remember.

YouTube - One Transistor Amplifier Demo

This is what I did next. I built a simple 2 transistor (2n2222s) CFL circuit. It has a 33 turn ( no reason for the number except to honor Mr. Tesla) wire loop around the base of the ignition coil to get a feed back signal for the first 2222. To control the input to the circuit I used an "adjustable step down switching voltage regulator" that dropped the supply power down to 4.5 volts at 20 milliamps ---enough to keep the CFL on dim. The battery source is 8 AA 1.2 volt 2000mAH rechargeable cells. It has been running for 26 hours now and I expect it to run a long long time.
A Very interesting experiment for the little 2n2222. The little engine that could. I'll name him Casey Jr. " I think I can. I think I can. I think I can".

Good for you Lid. You've shown some initiative again and figured out some stuff for yourself

I was going to post this earlier but I never got around to it.

Darlington pairs.

"A typical modern device has a current gain of 1000 or more, so that only a tiny base current is needed to make the pair switch on.

A drawback is a reduction in switching speed, because the first transistor cannot actively inhibit the base current of the second, which makes the device slow to switch off. To alleviate this, the second transistor often has a base resistor of a few hundred ohms[1].

The Darlington has more phase shift at high frequencies than a single transistor and hence can more easily become unstable with negative feedback (i.e., systems that use this configuration can have poor phase margin due to the extra transistor delay).


A Darlington pair can be sensitive enough to respond to the current passed by skin contact even at safe voltages. Thus it can form the input stage of a touch-sensitive switch."

Hmmm. So that is why touching the base of the transistor turns it on.

Take note of the above comment regarding switching speeds. Rembering that the highest voltage potentials in the ignition coil will come with the sharpest on and off we can provide. There is some room for experiments with the above recommendations I feel.

Also note that John Bedinis circuit employs 18k ohms of resistance from the collector of the transistor directly to the base

So perhaps we should experiment with bias resistance on the base of the 2222 and variable resistance between 2n2222 emitter and 2n3055 base. See if it gives us a sharper "off".

Also, maybe we should try another transistor? Aromaz originally had 3 in series didnt he? Perhaps 2n2222 > 2n3055> mjl21194. And for those interested in researching it further check out the "Sziklai pair"

@ Carl. You know that the maximum potential between two equal tesla coils are when they are 180 degrees out of phase from each other?

[hh1341]

@hh1341, maybe your circuit reach oscillation to unhearable frequency

You may be right.

At my age I'd be lucky to hear over 18 kHz .

Carl

You know......... 2 identical sounds will cancel each other out if they are 180 deg out of phase with each other.

@Aromaz, That is very interesting.
If you have time and feel that it is safe to do, can you try the experiment like the picture I post bellow.

I already did. See my posting #9 on:

[sucahyo]

Yes, here is the video:
YouTube - replication of Imhotep Radiant Oscillator - amp at open loop battery terminal

When in closed loop the battery charged at 3mA. Unfortunately I still don't have neon for experiment right now.

BTW, watch out when touching open terminal, always expect some serious shock if you are grounded. I already "tried" it repeatedly, maybe because I use computer power supply and my other hand pivoting on power supply case when turning it on.........

I still don't use car coil yet, but the voltage already painfull enough. Scary to think what it felt touching the HV output of car coil in this circuit.

Inspired by video by Aromaz, I try to measure the current behind a diode. After diode there is always about half the original current, no matter what leg the diode connected to. Either in forward or reverse direction, the current coming trough the diode is always half the original current. The current fluctuate though, so I can not measure precise amount. But this would still mean that diode do nothing to prevent back EMF propagation.

Since the diode reduce the current, the diode in original design may be best put at negative side of the battery, not at positive like currently used.

Another note, the current will be lower if the negative part of amp meter is grounded or touched. Current will be higher when I put the amp meter higher. I don't notice any charging with one wire only.

[Inquorate]

One wire from amp meter

@ Sucahyo - Input current 11mA, one lead from meter to circuit, other lead free, meter showing 1 amp, right?

I'm thinking of gotoluc's series LC tutorial video. The neon lights up when circuit in resonance. Only one leg of neon connected to coil / capacitor join. Other leg connected to one side of alligator clip, other clip unconnected. Neon lights up cause clip wire is aerial.

Perhaps your 1 amp reading was correct, and disconnected meter lead was an aerial, so actual current. Could you share a video of that? Perhaps put neon is series with meter?

Must take note of these 'odd' readings, and investigate anything weird and out of ordinary :-)

[sucahyo]

Experiment with air core coil (8 ohm 0.5 watt speaker spool) after relay coil resulted in lower charging rate. With air core coil in serie current draw is 11ma, during charging voltage is 0.4V plus battery voltage. Without air core coil current draw is 11.5, during charging voltage is 1.5V plus battery voltage.


@Aromaz, That is very interesting.

If you have time and feel that it is safe to do, can you try the experiment like the picture I post bellow. It is a modification of your circuit where coil is added to made it work closer like original Imhotep circuit. It may be able to charge a battery. One thing to be afraid of is the back EMF may damage all the transistor.

[Aromaz]

Video's on line at last:

Part 1: YouTube - Aromaz 027 - Back to basics HV Everywhere Part 1
Part 2: YouTube - Aromaz 028 - Back to basics HV Everywhere Part 2

Not in this video yet; but also had diode on base of 2222 with cathode towards 2222.

Various different frequencies depending on position - A or C and also depending on length of antenna / earth. Another aspect noted is sometimes I have full 2 mm spak on the Anode side - from just 50 cm antenna wire. That is very weird because clearly the 2222 is drawing - pulling -energy from antenna - enough to make 2 to 3 mm spark!!!!
